Subject: [PATCH 019/462] FunctionData refactor intermediate step

The refactor is not done yet and tests are not passing, but to proceed
with the refactor I need to make a decision that I'd like to be able to
easily revert if it ends up being the wrong one. Done so far:
  - Update documentation given FunctionData
  - Update all VariableCosts to refer to FunctionData
  - Update most cost-looking tuples to FunctionData
Not done:
  - `moi_tests` still fail
  - There is still a conflict in the typing of the data stored in
    parameter containers
  - Probably more issues I haven't gotten to in the tests yet

+Load the simulation results into memory for repeated reads. This is useful when loading

+means "variable, expression, etc.":
+  - Requests for an already cached variable at a lesser `count` than already cached do *not*
+    decrease the `count` of the cached variable
+  - Requests for an already cached variable at a greater `count` than already cached *do*
+    increase the `count` of the cached variable
+  - Requests for new variables are fulfilled without evicting existing variables
+
+Note that `count` is global across all variables, so increasing the `count` re-reads already
+cached variables. For each variable, each element must be the name encoded as a string, like
+`"ActivePowerVariable__ThermalStandard"` or a Tuple with its constituent types, like
+`(ActivePowerVariable, ThermalStandard)`. To clear the cache, use [`Base.empty!`](@ref).

Subject: [PATCH 121/462] FunctionData refactor intermediate step

The refactor is not done yet and tests are not passing, but to proceed
with the refactor I need to make a decision that I'd like to be able to
easily revert if it ends up being the wrong one. Done so far:
  - Update documentation given FunctionData
  - Update all VariableCosts to refer to FunctionData
  - Update most cost-looking tuples to FunctionData
Not done:
  - `moi_tests` still fail
  - There is still a conflict in the typing of the data stored in
    parameter containers
  - Probably more issues I haven't gotten to in the tests yet

 PowerSimulations can represent variable costs using a variety of different methods depending on the data available in each device. The following describes the objective function terms that are populated for each variable cost option.

+Load the simulation results into memory for repeated reads. This is useful when loading
+results from remote locations over network connections, when reading the same data very many
+times, etc. Multiple calls augment the cache according to these rules, where "variable"
+means "variable, expression, etc.":
+  - Requests for an already cached variable at a lesser `count` than already cached do *not*
+    decrease the `count` of the cached variable
+  - Requests for an already cached variable at a greater `count` than already cached *do*
+    increase the `count` of the cached variable
+  - Requests for new variables are fulfilled without evicting existing variables
+
+Note that `count` is global across all variables, so increasing the `count` re-reads already
+cached variables. For each variable, each element must be the name encoded as a string, like
+`"ActivePowerVariable__ThermalStandard"` or a Tuple with its constituent types, like
+`(ActivePowerVariable, ThermalStandard)`. To clear the cache, use [`Base.empty!`](@ref).

+# Formulations Introduction
+
+PowerSimulations.jl enables modularity in its formulations by assigning a `DeviceModel` to each `PowerSystems.jl` component type existing in a defined system.
+
+`PowerSimulations.jl` has a multiple `AbstractDeviceFormulation` subtypes that can be applied to different `PowerSystems.jl` device types, each dispatching to different methods for populating the optimization problem **variables**, **objective function**, **expressions** and **constraints**.
+
+## Example Formulation
+
+For example a typical optimization problem in a `DecisionModel` in `PowerSimulations.jl` with three `DeviceModel` has the abstract form of:
+
+```math
+\begin{align*}
+    &\min_{\boldsymbol{x}}~ \text{Objective\_DeviceModelA} + \text{Objective\_DeviceModelB} + \text{Objective\_DeviceModelC} \\
+    & ~~\text{s.t.} \\
+    & \hspace{0.9cm} \text{Constraints\_NetworkModel} \\
+    & \hspace{0.9cm} \text{Constraints\_DeviceModelA} \\
+    & \hspace{0.9cm} \text{Constraints\_DeviceModelB} \\
+    & \hspace{0.9cm} \text{Constraints\_DeviceModelC} 
+\end{align*}
+```
+
+Suppose this is a system with the following characteristics:
+- Horizon: 48 hours
+- Interval: 24 hours
+- Resolution: 1 hour
+- Three Buses: 1, 2 and 3
+- One `ThermalStandard` (device A) unit at bus 1
+- One `RenewableDispatch` (device B) unit at bus 2
+- One `PowerLoad` (device C) at bus 3
+- Three `Line` that connects all the buses
+
+Now, we assign the following `DeviceModel` to each `PowerSystems.jl` with:
+
+| Type      | Formulation |
+| ----------- | ----------- |
+| Network     | `CopperPlatePowerModel`       |
+| `ThermalStandard`  | `ThermalDispatchNoMin` |
+| `RenewableDispatch`  | `RenewableFullDispatch` |
+| `PowerLoad`  | `StaticPowerLoad` |
+
+Note that we did not assigned any `DeviceModel` to `Line` since the `CopperPlatePowerModel` used for the network assumes that everything is lumped in the same node (like a copper plate with infinite capacity), and hence there are no flows between buses that branches can limit.
+
+Each `DeviceModel` formulation is described in specific in their respective page, but the overall optimization problem will end-up as:
+
+```math
+\begin{align*}
+    &\min_{\boldsymbol{p}^\text{th}, \boldsymbol{p}^\text{re}}~ \sum_{t=1}^{48} C^\text{th} p_t^\text{th} - C^\text{re} p_t^\text{re} \\
+    & ~~\text{s.t.} \\
+    & \hspace{0.9cm} p_t^\text{th} + p_t^\text{re} = P_t^\text{load}, \quad \forall t \in {1,\dots, 48} \\
+    & \hspace{0.9cm} 0 \le p_t^\text{th} \le P^\text{th,max} \\
+    & \hspace{0.9cm} 0 \le p_t^\text{re} \le \text{ActivePowerTimeSeriesParameter}_t 
+\end{align*}
+```
+
+Note that the `StaticPowerLoad` does not impose any cost to the objective function or any constraint, but add its power demand to the supply-balance demand of the `CopperPlatePowerModel` used. Since we are using the `ThermalDispatchNoMin` formulation for the thermal generation, the lower bound for the power is 0, instead of ``P^\text{th,min}``. In addition, we are assuming a linear cost ``c^\text{th}``. Finally, the `RenewableFullDispatch` formulation allows the dispatch of the renewable unit to be between 0 and its maximum injection time series ``p_t^\text{re,param}``.
+
+# Nomenclature
+
+In the formulations described in the other pages, the nomenclature is as follows:
+- Lowercase letters are used for variables, e.g., ``p`` for power.
+- Uppercase letters are used for parameters, e.g., ``C`` for costs.
+- Subscripts are used for indexing, e.g., ``(\cdot)_t`` for indexing at time ``t``.
+- Superscripts are used for descriptions, e.g., ``(\cdot)^\text{th}`` to describe a thermal (th) variable/parameter.
+- Bold letters are used for vectors, e.g., ``\boldsymbol{p} = \{p\}_{1,\dots,24}``.

 # [Network Formulations](@id network_formulations)
 
-TODO
+Network formulations are used to describe how the network and buses are handled when constructing constraints. The most common constraint decided by the network formulation is the supply-demand balance constraint. Available Network Models are:
+
+| Formulation      | Description |
+| ----- | ---- |
+| `CopperPlatePowerModel` | Copper plate connection between all components, i.e. infinite transmission capacity |
+| `AreaBalancePowerModel` | Network model approximation to represent inter-area flow with each area represented as a single node |
+| `PTDFPowerModel` | Uses the PTDF factor matrix to compute the fraction of power transferred in the network across the branches |
+
+[`PowerModels.jl`](https://github.com/lanl-ansi/PowerModels.jl) available formulations:
+- Exact non-convex models: `ACPPowerModel`, `ACRPowerModel`, `ACTPowerModel`.
+- Linear approximations: `DCPPowerModel`, `NFAPowerModel`.
+- Quadratic approximations: `DCPLLPowerModel`, `LPACCPowerModel`
+- Quadratic relaxations: `SOCWRPowerModel`, `SOCWRConicPowerModel`, `SOCBFPowerModel`, `SOCBFConicPowerModel`, `QCRMPowerModel`, `QCLSPowerModel`.
+- SDP relaxations: `SDPWRMPowerModel`, `SparseSDPWRMPowerModel`.
+
+All of these formulations are described in the [PowerModels.jl documentation](https://lanl-ansi.github.io/PowerModels.jl/stable/formulation-details/) and will not be described here.

+!!! note
+    Thermal units can include multiple terms added to the objective function, such as no-load cost, turn-on/off cost, fixed cost and variable cost. In addition, variable costs can be linear, quadratic or piecewise-linear formulations. These methods are properly described in the cost function document: TODO. 
+
+
+!!! note
+    The usage of reactive power variables and constraints will depend on the network model used, i.e. if it uses (or not) reactive power. If the network model is purely active power based, then no variables and constraints related to reactive power are created. For the sake of completion, if the formulation allows the usage of reactive power it will be included.
+
+!!! note
+    Reserve variables for services are not included in the formulation, albeit their inclusion change the variables, expressions, constraints and objective functions created. A detailed description of the implications in the optimization models is described in the [Service formulation](@ref service_formulation) section.

+
+**Expressions:**
+
+Each `FlowActivePowerToFromVariable` ``f^\text{to-from}`` and `FlowActivePowerFromToVariable` ``f^\text{from-to}``  is added to the nodal balance expression `ActivePowerBalance`, by adding the respective flow in the receiving bus and subtracting it from the sending bus. That is,  ``f^\text{to-from}`` adds the flow to the `from` bus, and subtracts the flow from the `to` bus, while ``f^\text{from-to}`` adds the flow to the `to` bus, and subtracts the flow from the `from` bus  This is used then to compute the AC flows using the PTDF equation.
+
+In addition, the `HVDCLosses` are subtracted to the `from` bus in the `ActivePowerBalance` expression.

+# [Piecewise linear cost functions](@id pwl_cost)
+
+The choice for piecewise-linear (PWL) cost representation in  `PowerSimulations.jl` is equivalent to the so-called λ-model from the paper [_The Impacts of Convex Piecewise Linear Cost Formulations on AC Optimal Power Flow_](https://www.sciencedirect.com/science/article/pii/S0378779621001723). The SOS constraints in each model are only implemented if the data for PWL is not convex.
+
+## Special Ordered Set (SOS) Constraints
+
+A special ordered set (SOS) is an ordered set of variables used as an additional way to specify integrality conditions in an optimization model.
+
+- Special Ordered Sets of type 1 (SOS1) are a set of variables, at  most one of which can take a non-zero value, all others being at 0. They most frequently applications is in a a set of variables that are actually binary variables: in other words, we have to choose at most one from a set of possibilities.
+- Special Ordered Sets of type 2 (SOS2) are an ordered set of non-negative variables, of which at most two can be non-zero, and if two are non-zero these must be consecutive in their ordering. Special Ordered Sets of type 2 are typically used to model non-linear functions of a variable in a linear model, such as non-convex quadratic functions using PWL functions.
+
+## Standard representation of PWL costs
+
+Piecewise-linear costs are defined by a sequence of points representing the line segments for each generator: ``(P_k^\text{max}, C_k)`` on which we assume ``C_k`` is the cost of generating ``P_k^\text{max}`` power, and ``k \in \{1,\dots, K\}`` are the number of segments each generator cost function has.
+
+### Commitment formulation
+
+ With this the standard representation of PWL costs for a thermal unit commitment is given by:
+
+```math
+\begin{align*}
+ \min_{\substack{p_{t}, \delta_{k,t}}}
+ & \sum_{t \in \mathcal{T}} \left(\sum_{k \in \mathcal{K}} C_{k,t} \delta_{k,t} \right) \Delta t\\
+ & \sum_{k \in \mathcal{K}} P_{k}^{\text{max}} \delta_{k,t} = p_{t} & \forall t \in \mathcal{T}\\
+ & \sum_{k \in \mathcal{K}} \delta_{k,t} = u_{t} & \forall t \in \mathcal{T}\\
+ & P^{\text{min}} u_{t} \leq p_{t} \leq P^{\text{max}} u_{t} & \forall t \in \mathcal{T}\\
+ &\left \{\delta_{1,t}, \dots, \delta_{K,t} \right \} \in \text{SOS}_{2} & \forall t \in \mathcal{T}
+\end{align*}
+```
+on which ``\delta_{k,t} \in [0,1]`` is the interpolation variable, ``p`` is the active power of the generator and ``u \in \{0,1\}`` is the commitment variable of the generator. In the case of a PWL convex costs, i.e. increasing slopes, the SOS constraint is omitted.
+
+### Dispatch formulation
+
+```math
+\begin{align*}
+ \min_{\substack{p_{t}, \delta_{k,t}}}
+ & \sum_{t \in \mathcal{T}} \left(\sum_{k \in \mathcal{K}} C_{k,t} \delta_{k,t} \right) \Delta t\\
+ & \sum_{k \in \mathcal{K}} P_{k}^{\text{max}} \delta_{k,t} = p_{t} & \forall t \in \mathcal{T}\\
+ & \sum_{k \in \mathcal{K}} \delta_{k,t} = \text{on}_{t} & \forall t \in \mathcal{T}\\
+ & P^{\text{min}} \text{on}_{t} \leq p_{t} \leq P^{\text{max}} \text{on}_{t} & \forall t \in \mathcal{T}\\
+ &\left \{\delta_{i,t}, \dots, \delta_{k,t} \right \} \in \text{SOS}_{2} & \forall t \in \mathcal{T}
+\end{align*}
+```
+on which ``\delta_{k,t} \in [0,1]`` is the interpolation variable, ``p`` is the active power of the generator and ``\text{on} \in \{0,1\}`` is the parameter that decides if the generator is available or not. In the case of a PWL convex costs, i.e. increasing slopes, the SOS constraint is omitted.

 ## Adding slacks to the model
 
+One of the most common infeasibility issues observed is due to not enough generation to supply demand, or conversely, excessive fixed (non-curtailable) generation in a low demand scenario. 
+
+The recommended solution for any of these cases is adding slack variables to the network model, for example:
+
+```julia
+template_uc = ProblemTemplate(
+        NetworkModel(
+            CopperPlatePowerModel,
+            use_slacks=true,
+        ),
+    )
+```
+will add slack variables to the `ActivePowerBalance` expression.
+
+In this case, if the problem is now feasible, the user can check the solution of the variables `SystemBalanceSlackUp` and `SystemBalanceSlackDown`, and if one value is greater than zero, it represents that not enough generation (for Slack Up) or not enough demand (for Slack Down) in the optimization problem.
+
+### Services cases
+
+In many scenarios, certain units are also required to provide reserve requirements, e.g. thermal units mandated to provide up-regulation. In such scenarios, it is also possible to add slack variables, by specifying the service model (`RangeReserve`) for the specific service type (`VariableReserve{ReserveUp}`) as:
+```julia
+set_service_model!(
+    template_uc,
+    ServiceModel(
+        VariableReserve{ReserveUp},
+        RangeReserve;
+        use_slacks=true
+    ),
+)
+```
+Again, if the problem is now feasible, check the solution of `ReserveRequirementSlack` variable, and if it is larger than zero in a specific time-step, then it is evidence that there is not enough reserve available to satisfy the requirement.
+
 ## Getting the infeasibility conflict
+
+Some solvers allows to identify which constraints and variables are producing the infeasibility, by finding the irreducible infeasible set (IIS), that is the subset of constraints and variable bounds that will become feasible if any single constraint or variable bound is removed. 
+
+To enable this feature in `PowerSimulations` the keyword argument `calculate_conflict` must be set to `true`, when creating the `DecisionModel`. Note that not all solvers allow the computation of the IIS, but most commercial solvers have this capability. It is also recommended to enable the keyword argument `store_variable_names=true` to help understanding which variables are with infeasibility issues.
+
+The following code creates a decision model with the `Xpress` optimizer, and enabling the `calculate_conflict=true` keyword argument.
+
+```julia
+DecisionModel(
+    template_ed,
+    sys_rts_rt;
+    name="ED",
+    optimizer=optimizer_with_attributes(Xpress.Optimizer, "MIPRELSTOP" => 1e-2),
+    optimizer_solve_log_print=true,
+    calculate_conflict=true,
+    store_variable_names=true,
+)
+```
+
+Here is an example on how the IIS will be displayed as:

+
+Note that the IIS clearly identify that the issue is happening at time step 26, and constraints are related with the `CopperPlateBalanceConstraint__System`, with multiple upper bound constraints, for the hybrid system, renewable units and thermal units. This highlights that there may not be enough generation in the system. Indeed, by enabling system slacks, the problem become feasible.

+Finally, the infeasible model is exported in a `json` file that can be loaded directly in `JuMP` to be explored. More information about this is [available here](https://jump.dev/JuMP.jl/stable/moi/submodules/FileFormats/overview/#Read-from-file).

 Templates are used to specify the modeling properties of the devices and network that are going to he used to specify a problem.
 A `ProblemTemplate` is just a collection of `DeviceModel`s that allows the user to specify the formulations
 of each set of devices (by device type) independently so that the modeler can adjust the level of detail according to the question of interest and the available data.

 ## Feedforward
 
-TODO
+The definition of exactly what information is passed using the defined chronologies is accomplished using FeedForwards.
+
+Specifically, a FeedForward is used to define what to do with information being passed with an inter-stage chronology in a Simulation. The most common FeedForward is the `SemiContinuousFeedForward` that affects the semi-continuous range constraints of thermal generators in the economic dispatch problems based on the value of the (already solved) unit-commitment variables.
+
+The creation of a FeedForward requires at least to specify the `component_type` on which the FeedForward will be applied. The `source` variable specify which variable will be taken from the problem solved, for example the commitment variable of the thermal unit in the unit commitment problem. Finally, the `affected_values` specify which variables will be affected in the problem to be solved, for example the next economic dispatch problem.
+
+The following code specify the creation of semi-continuous range constraints on the `ActivePowerVariable` based on the solution of the commitment variable `OnVariable` for all `ThermalStandard` units.
+
+```julia
+SemiContinuousFeedforward(
+    component_type=ThermalStandard,
+    source=OnVariable,
+    affected_values=[ActivePowerVariable],
+)
+```
+
+## Chronologies
+
+In PowerSimulations, chronologies define where information is flowing. There are two types
+of chronologies.
+
+- inter-stage chronologies: Define how information flows between stages. e.g. day-ahead solutions are used to inform economic dispatch problems
+- intra-stage chronologies: Define how information flows between multiple executions of a single stage. e.g. the dispatch setpoints of the first period of an economic dispatch problem are constrained by the ramping limits from setpoints in the final period of the previous problem.
 
 ## Sequencing
 
 In a typical simulation pipeline, we want to connect daily (24-hours) day-ahead unit commitment problems, with multiple economic dispatch problems. Usually, our day-ahead unit commitment problem will have an hourly (1-hour) resolution, while the economic dispatch will have a 5-minute resolution.
 
 Depending on your problem, it is common to use a 2-day look-ahead for unit commitment problems, so in this case, the Day-Ahead problem will have: resolution = Hour(1) with interval = Hour(24) and horizon = 48. In the case of the economic dispatch problem, it is common to use a look-ahead of two hours. Thus, the Real-Time problem will have: resolution = Minute(5), with interval = Minute(5) (we only store the first operating point) and horizon = 24 (24 time steps of 5 minutes are 120 minutes, that is 2 hours).
+
+## Simulation Setup
+
+The following code creates the entire simulation pipeline:
+
+```julia
+# We assume that the templates for UC and ED are ready
+# sys_da has the resolution of 1 hour:
+# with the 24 hours interval and horizon of 48 hours.
+# sys_rt has the resolution of 5 minutes:
+# with a 5-minute interval and horizon of 2 hours (24 time steps)
+
+# Create the UC Decision Model
+decision_model_uc = DecisionModel(
+    template_uc,
+    sys_da;
+    name="UC",
+    optimizer=optimizer_with_attributes(
+        Xpress.Optimizer,
+        "MIPRELSTOP" => 1e-1,
+    ),
+)
+
+# Create the ED Decision Model
+decision_model_ed = DecisionModel(
+    template_ed,
+    sys_rt;
+    name="ED",
+    optimizer=optimizer_with_attributes(Xpress.Optimizer),
+)
+
+# Specify the SimulationModels using a Vector of decision_models: UC, ED
+sim_models = SimulationModels(
+    decision_models=[
+        decision_model_uc,
+        decision_model_ed,
+    ],
+)
+
+# Create the FeedForwards:
+semi_ff = SemiContinuousFeedforward(
+    component_type=ThermalStandard,
+    source=OnVariable,
+    affected_values=[ActivePowerVariable],
+)
+
+# Specify the sequencing:
+sim_sequence = SimulationSequence(
+    # Specify the vector of decision models: sim_models
+    models=sim_models,
+    # Specify a Dict of feedforwards on which the FF applies
+    # based on the DecisionModel name, in this case "ED"
+    feedforwards=Dict(
+        "ED" => [semi_ff],
+    ),
+    # Specify the chronology, in this case inter-stage
+    ini_cond_chronology=InterProblemChronology(),
+)
+
+# Construct the simulation:
+sim = Simulation(
+    name="compact_sim",
+    steps=10, # 10 days
+    models=sim_models,
+    sequence=sim_sequence,
+    # Specify the start_time as a DateTime: e.g. DateTime("2020-10-01T00:00:00")
+    initial_time=start_time,
+    # Specify a temporary folder to avoid storing logs if not needed
+    simulation_folder=mktempdir(cleanup=true),
+)
+
+# Build the decision models and simulation setup
+build!(sim)
+
+# Execute the simulation using the Optimizer specified in each DecisionModel
+execute!(sim, enable_progress_bar=true)
+```

 # Definitions
 
+## A
+
+* *Attributes*: Certain device formulations can be customized by specifying attributes that will include/remove certain variables, expressions and/or constraints. For example, in `StorageSystemsSimulations.jl`, the device formulation of `StorageDispatchWithReserves` can be specified with the following dictionary of attributes:
+```julia
+set_device_model!(
+    template,
+    DeviceModel(
+        GenericBattery,
+        StorageDispatchWithReserves;
+        attributes=Dict{String, Any}(
+            "reservation" => false,
+            "cycling_limits" => false,
+            "energy_target" => false,
+            "complete_coverage" => false,
+            "regularization" => false,
+        ),
+    ),
+)
+```
+Changing the attributes between `true` or `false` can enable/disable multiple aspects of the formulation.
+
+## C
+
+* *Chronologies:* In `PowerSimulations.jl`, chronologies define where information is flowing. There are two types of chronologies. 1) **inter-stage chronologies** (`InterProblemChronology`) that define how information flows between stages. e.g. day-ahead solutions are used to inform economic dispatch problems; and 2) **intra-stage chronologies** (`IntraProblemChronology`) that define how information flows between multiple executions of a single stage. e.g. the dispatch setpoints of the first period of an economic dispatch problem are constrained by the ramping limits from setpoints in the final period of the previous problem.

 ## D
 
-* *Decision Problem*: A decision problem calculates the desired system operation based on forecasts of uncertain inputs and information about the state of the system. The output of a decision problem represents the policies used to drive the set-points of the system's devices, like generators or switches, and depends on the purpose of the problem. See the [Decision Model Tutorial](op_problem_tutorial) to learn more about solving individual problems.

 ## E
 
 * *Emulation Problem*: An emulation problem is used to mimic the system's behavior subject to an incoming decision and the realization of a forecasted inputs. The solution of the emulator produces outputs representative of the system performance when operating subject the policies resulting from the decision models.
 
+## F
+
+* *FeedForward*: The definition of exactly what information is passed using the defined chronologies is accomplished using FeedForwards. Specifically, a FeedForward is used to define what to do with information being passed with an inter-stage chronology in a Simulation. The most common FeedForward is the `SemiContinuousFeedForward` that affects the semi-continuous range constraints of thermal generators in the economic dispatch problems based on the value of the (already solved) unit-commitment variables.

 ## H
 
 * *Horizon*: The number of steps in the look-ahead of a decision problem. For instance, a Day-Ahead problem usually has a 48 step horizon. Check the time [Time Series Data Section in PowerSystems.jl](https://nrel-sienna.github.io/PowerSystems.jl/stable/modeler_guide/time_series/)

 ## R
 
 * *Resolution*: The amount of time between timesteps in a simulation. For instance 1-hour or 5-minutes. In Julia these are defined using the syntax `Hour(1)` and `Minute(5)`. Check the time [Time Series Data Section in PowerSystems.jl](https://nrel-sienna.github.io/PowerSystems.jl/stable/modeler_guide/time_series/)

+## S
+
+* *Simulation*: A simulation is a pre-determined sequence of decision problems in a way that solving it, resembles the solution procedures commonly used by operators. The most common simulation model is the solution of a Unit Commitment and Economic Dispatch sequence of problems.
+
+* *Solver*: A solver is a software package that incorporates algorithms for finding solutions to one or more classes of optimization problem. For example, FICO Xpress is a commercial optimization solver for linear programming (LP), convex quadratic programming (QP) problems, convex quadratically constrained quadratic programming (QCQP), second-order cone programming (SOCP) and their mixed integer counterparts. **A solver is required to be specified** in order to solve any computer optimization problem.

+
+* *Template*: A `ProblemTemplate` is just a collection of `DeviceModel`s that allows the user to specify the formulations of each set of devices (by device type) independently so that the modeler can adjust the level of detail according to the question of interest and the available data. For more information about valid `DeviceModel`s and their mathematical representations, check out the [Formulation Library](@ref formulation_intro).

+# [Read results](@id read_results)
+
+Once a `DecisionModel` is solved via `solve!(model)` or a Simulation is executed (and solved) via `execute!(simulation)`, the results are stored and can be accessed directly in the REPL for result exploration and plotting.
+
+## Read results of a Decision Problem
+
+Once a `DecisionModel` is solved, results are accessed using `ProblemResults(model)` as follows:
+
+```julia
+# The DecisionModel is already constructed
+build!(model, output_dir = mktempdir())
+solve!(model)
+
+results = ProblemResults(model)
+```
+
+The output will showcase the available expressions, parameters and variables to read. For example it will look like:

+
+Then the following code can be used to read results:
+
+```julia
+# Read active power of Thermal Standard
+thermal_active_power = read_variable(results, "ActivePowerVariable__ThermalStandard")
+
+# Read max active power parameter of RenewableDispatch
+renewable_param = read_parameter(results, "ActivePowerTimeSeriesParameter__RenewableDispatch")
+
+# Read cost expressions of ThermalStandard units
+cost_thermal = read_expression(results, "ProductionCostExpression__ThermalStandard")
+
+# Read dual variables
+dual_balance_constraint = read_dual(results, "CopperPlateBalanceConstraint__System")
+
+# Read auxiliary variables
+aux_var_result = read_aux_variable(results, "CumulativeCyclingCharge__HybridSystem")
+```
+
+Results will be in the form of DataFrames that can be easily explored.
+
+## Read results of a Simulation
+
+```julia
+# The Simulation is already constructed
+build!(sim)
+execute!(sim; enable_progress_bar=true)
+
+results_sim = SimulationResults(sim)
+```
+
+As an example, the `SimulationResults` printing will look like:
+
+```raw
+Decision Problem Results
+┌──────────────┬─────────────────────┬──────────────┬─────────────────────────┐
+│ Problem Name │ Initial Time        │ Resolution   │ Last Solution Timestamp │
+├──────────────┼─────────────────────┼──────────────┼─────────────────────────┤
+│ ED           │ 2020-10-02T00:00:00 │ 60 minutes   │ 2020-10-09T23:00:00     │
+│ UC           │ 2020-10-02T00:00:00 │ 1440 minutes │ 2020-10-09T00:00:00     │

+┌─────────────────┬───────────┐
+│ Name            │ Emulator  │
+│ Resolution      │ 5 minutes │
+│ Number of steps │ 2304      │
+└─────────────────┴───────────┘
+```
+
+With this, it is possible to obtain results of each `DecisionModel` and `EmulationModel` as follows:
+
+```julia
+# Use the Problem Name for Decision Problems
+results_uc = get_decision_problem_results(results_sim, "UC")
+results_ed = get_decision_problem_results(results_sim, "ED")
+results_emulator = get_emulation_problem_results(results_dcp)
+```
+
+Once we have each decision (or emulation) problem results, we can explore directly using the approach for Decision Models, mentioned in the previous section.
+
+### Reading solutions for all simulation steps
+
+In this case, using `read_variable` (or read expression, parameter or dual), will return a dictionary of all steps (of that Decision Problem). For example, the following code:
+
+```julia
+thermal_active_power = read_variable(results_uc, "ActivePowerVariable__ThermalStandard")
+```
+will return:
+```
+DataStructures.SortedDict{Any, Any, Base.Order.ForwardOrdering} with 8 entries:
+  DateTime("2020-10-02T00:00:00") => 72×54 DataFrame…
+  DateTime("2020-10-03T00:00:00") => 72×54 DataFrame…
+  DateTime("2020-10-04T00:00:00") => 72×54 DataFrame…
+  DateTime("2020-10-05T00:00:00") => 72×54 DataFrame…
+  DateTime("2020-10-06T00:00:00") => 72×54 DataFrame…
+  DateTime("2020-10-07T00:00:00") => 72×54 DataFrame…
+  DateTime("2020-10-08T00:00:00") => 72×54 DataFrame…
+  DateTime("2020-10-09T00:00:00") => 72×54 DataFrame…
+```
+That is, a sorted dictionary for each simulation step, using as a key the initial timestamp for that specific simulation step.
+
+Note that in this case, each DataFrame, has a dimension of ``72 \times 54``, since the horizon is 72 hours (number of rows), but the interval is only 24 hours. Indeed, note the initial timestamp of each simulation step is the beginning of each day, i.e. 24 hours. Finally, there 54 columns, since this example system has 53 `ThermalStandard` units (plus 1 column for the timestamps). The user is free to explore the solution of any simulation step as needed.
+
+### Reading the "realized" solution (i.e. the interval)
+
+Using `read_realized_variable` (or read realized expression, parameter or dual), will return the DataFrame of the realized solution of any specific variable. That is, it will concatenate the corresponding simulation step with the specified interval of that step, to construct a single DataFrame with the "realized solution" of the entire simulation.
+
+For example, the code:
+```julia
+th_realized_power = read_realized_variable(results_uc, "ActivePowerVariable__ThermalStandard")
+```
+will return:
+```raw
+92×54 DataFrame
+ Row │ DateTime             322_CT_6      321_CC_1  202_STEAM_3   223_CT_4  123_STEAM_2    213_CT_1  223_CT_6  313_CC_1  101_STEAM_3  123_C ⋯

 In a typical simulation pipeline, we want to connect daily (24-hours) day-ahead unit commitment problems, with multiple economic dispatch problems. Usually, our day-ahead unit commitment problem will have an hourly (1-hour) resolution, while the economic dispatch will have a 5-minute resolution.
 
-Depending on your problem, it is common to use a 2-day look-ahead for unit commitment problems, so in this case, the Day-Ahead problem will have: resolution = Hour(1) with interval = Hour(24) and horizon = 48. In the case of the economic dispatch problem, it is common to use a look-ahead of two hours. Thus, the Real-Time problem will have: resolution = Minute(5), with interval = Minute(5) (we only store the first operating point) and horizon = 24 (24 time steps of 5 minutes are 120 minutes, that is 2 hours).

 # [`PowerSystems.Service` Formulations](@id service_formulations)
 
-TODO
+`Services` (or ancillary services) are models used to ensure that there is necessary support to the power grid from generators to consumers, in order to ensure reliable operation of the system.
+
+The most common application for ancillary services are reserves, i.e., generation (or load) that is not currently being used, but can be quickly made available in case of unexpected changes of grid conditions, for example a sudden loss of load or generation.
+
+A key challenge of adding services to a system, from a mathematical perspective, is specifying which units contribute to the specified requirement of a service, that implies the creation of new variables (such as reserve variables) and modification of constraints.
+
+In this documentation, we first specify the available `Services` in the grid, and what requirements impose in the system, and later we discuss the implication on device formulations for specific units.
+
+## `RangeReserve`
+
+For each service ``s`` of the model type `RangeReserve` the following variables are created:
+
+**Variables**:
+
+- [`ActivePowerReserveVariable`](@ref):
+    - Bounds: [0.0, ]
+    - Symbol: ``r_{d}`` for ``d`` in contributing devices to the service ``s``
+If slacks are enabled:
+- [`ReserveRequirementSlack`](@ref):
+    - Bounds: [0.0, ]
+    - Symbol: ``r^\text{sl}``
+
+Depending on the `PowerSystems.jl` type associated to the `RangeReserve` formulation model, the parameters are:
+
+**Static Parameters**
+
+- ``\text{PF}`` = `PowerSystems.get_max_participation_factor(service)`
+
+For a `StaticReserve` `PowerSystems` type:
+- ``\text{Req}`` = `PowerSystems.get_requirement(service)`
+
+**Time Series Parameters** 
+
+For a `VariableReserve` `PowerSystems` type:
+```@eval
+using PowerSimulations
+using PowerSystems
+using DataFrames
+using Latexify
+combos = PowerSimulations.get_default_time_series_names(VariableReserve, RangeReserve)
+combo_table = DataFrame(
+    "Parameter" => map(x -> "[`$x`](@ref)", collect(keys(combos))),
+    "Default Time Series Name" => map(x -> "`$x`", collect(values(combos))),
+    )
+mdtable(combo_table, latex = false)
+```
+
+**Relevant Methods:**
+
+``\mathcal{D}_s`` = `PowerSystems.get_contributing_devices(system, service)`: Set (vector) of all contributing devices to the service ``s`` in the system.
+
+**Expressions:**
+
+Adds the `ActivePowerReserveVariable` for upper/lower bound expressions of contributing devices.
+
+For `ReserveUp` types, the variable is added to `ActivePowerRangeExpressionUB`, such that this expression considers both the `ActivePowerVariable` and its reserve variable. Similarly, For `ReserveDown` types, the variable is added to `ActivePowerRangeExpressionLB`, such that this expression considers both the `ActivePowerVariable` and its reserve variable
+
+
+*Example*: for a thermal unit ``d`` contributing to two different `ReserveUp` ``s_1, s_2`` services (e.g. Reg-Up and Spin):
+```math
+\text{ActivePowerRangeExpressionUB}_{t} = p_t^\text{th} + r_{s_1,t} + r_{s_2, t} \le P^\text{th,max}
+```
+similarly if ``s_3`` is a `ReserveDown` service (e.g. Reg-Down):
+```math
+\text{ActivePowerRangeExpressionLB}_{t} = p_t^\text{th} - r_{s_3,t}  \ge P^\text{th,min}
+```
+
+
+**Constraints:** 
+
+A RangeReserve implements two fundamental constraints. The first is that the sum of all reserves of contributing devices must be larger than the `RangeReserve` requirement. Thus, for a service ``s``:
+
+```math
+\sum_{d\in\mathcal{D}_s} r_{d,t} + r_t^\text{sl} \ge \text{Req},\quad \forall t\in \{1,\dots, T\} \quad \text{(for a StaticReserve)} \\
+\sum_{d\in\mathcal{D}_s} r_{d,t} + r_t^\text{sl} \ge \text{RequirementTimeSeriesParameter}_{t},\quad \forall t\in \{1,\dots, T\} \quad \text{(for a VariableReserve)}
+```
+
+In addition, there is a restriction on how much each contributing device ``d`` can contribute to the requirement, based on the max participation factor allowed.
+
+```math
+r_{d,t} \le \text{Req} \cdot \text{PF} ,\quad \forall d\in \mathcal{D}_s, \forall t\in \{1,\dots, T\} \quad \text{(for a StaticReserve)} \\
+r_{d,t} \le \text{RequirementTimeSeriesParameter}_{t} \cdot \text{PF}\quad  \forall d\in \mathcal{D}_s, \forall t\in \{1,\dots, T\}, \quad \text{(for a VariableReserve)}
+```

+**Variables**:

+    - Bounds: [0.0, ]

+
+**Time Series Parameters** 
+
+TODO
+
+**Relevant Methods:**
+
+``\mathcal{D}_s`` = `PowerSystems.get_contributing_devices(system, service)`: Set (vector) of all contributing devices to the service ``s`` in the system.
+
+**Objective:**
+
+TODO
+
+**Expressions:**
+
+Adds the `ActivePowerReserveVariable` for upper/lower bound expressions of contributing devices.
+
+For `ReserveUp` types, the variable is added to `ActivePowerRangeExpressionUB`, such that this expression considers both the `ActivePowerVariable` and its reserve variable. Similarly, For `ReserveDown` types, the variable is added to `ActivePowerRangeExpressionLB`, such that this expression considers both the `ActivePowerVariable` and its reserve variable
+
+
+*Example*: for a thermal unit ``d`` contributing to two different `ReserveUp` ``s_1, s_2`` services (e.g. Reg-Up and Spin):
+```math
+\text{ActivePowerRangeExpressionUB}_{t} = p_t^\text{th} + r_{s_1,t} + r_{s_2, t} \le P^\text{th,max}
+```
+similarly if ``s_3`` is a `ReserveDown` service (e.g. Reg-Down):
+```math
+\text{ActivePowerRangeExpressionLB}_{t} = p_t^\text{th} - r_{s_3,t}  \ge P^\text{th,min}
+```
+
+**Constraints:** 
+
+A `StepwiseCostReserve` implements a single constraint, such that the sum of all reserves of contributing devices must be larger than the `ServiceRequirementVariable` variable. Thus, for a service ``s``:
+
+```math
+\sum_{d\in\mathcal{D}_s} r_{d,t}  \ge \text{req}_t,\quad \forall t\in \{1,\dots, T\}  
+```

These decreasing cost represent the scarcity prices of not having sufficient reserves. For example, if the variable ``\text{req} = 0``, then a really high cost is paid for not having enough reserves, and if ``\text{req}`` is larger, then a lower cost (or even zero) is paid.

+\text{ActivePowerRangeExpressionLB}_{t} = p_t^\text{th} - r_{s_3,t}  \ge P^\text{th,min}
+```
+
+**Constraints:** 
+
+A `StepwiseCostReserve` implements a single constraint, such that the sum of all reserves of contributing devices must be larger than the `ServiceRequirementVariable` variable. Thus, for a service ``s``:

+- ``R^\text{th,up}`` = `PowerSystems.get_ramp_limits(device).down` for thermal contributing devices
+
+Other parameters:
+
+- ``\Delta T``: Resolution of the problem in minutes.
+
+**Time Series Parameters** 
+
+For a `VariableReserve` `PowerSystems` type:
+```@eval
+using PowerSimulations
+using PowerSystems
+using DataFrames
+using Latexify
+combos = PowerSimulations.get_default_time_series_names(VariableReserve, NonSpinningReserve)
+combo_table = DataFrame(
+    "Parameter" => map(x -> "[`$x`](@ref)", collect(keys(combos))),
+    "Default Time Series Name" => map(x -> "`$x`", collect(values(combos))),
+    )
+mdtable(combo_table, latex = false)
+```
+
+**Relevant Methods:**
+
+- ``\mathcal{D}_s`` = `PowerSystems.get_contributing_devices(system, service)`: Set (vector) of all contributing devices to the service ``s`` in the system.
+
+**Objective:**
+
+Add a large proportional cost to the objective function if slack variables are used ``+ r^\text{sl} \cdot 10^5``. In addition adds the default cost for `ActivePowerReserveVariables` as a proportional cost.
+
+**Expressions:**
+
+Adds the `ActivePowerReserveVariable` for upper/lower bound expressions of contributing devices.
+
+For `ReserveUp` types, the variable is added to `ActivePowerRangeExpressionUB`, such that this expression considers both the `ActivePowerVariable` and its reserve variable. Similarly, For `ReserveDown` types, the variable is added to `ActivePowerRangeExpressionLB`, such that this expression considers both the `ActivePowerVariable` and its reserve variable
+
+
+*Example*: for a thermal unit ``d`` contributing to two different `ReserveUp` ``s_1, s_2`` services (e.g. Reg-Up and Spin):
+```math
+\text{ActivePowerRangeExpressionUB}_{t} = p_t^\text{th} + r_{s_1,t} + r_{s_2, t} \le P^\text{th,max}
+```
+similarly if ``s_3`` is a `ReserveDown` service (e.g. Reg-Down):
+```math
+\text{ActivePowerRangeExpressionLB}_{t} = p_t^\text{th} - r_{s_3,t}  \ge P^\text{th,min}
+```
+
+**Constraints:** 
+
+A NonSpinningReserve implements three fundamental constraints. The first is that the sum of all reserves of contributing devices must be larger than the `RampReserve` requirement. Thus, for a service ``s``:
+
+```math
+\sum_{d\in\mathcal{D}_s} r_{d,t} + r_t^\text{sl} \ge \text{RequirementTimeSeriesParameter}_{t},\quad \forall t\in \{1,\dots, T\}
+```
+
+In addition, there is a restriction on how much each contributing device ``d`` can contribute to the requirement, based on the max participation factor allowed.
+
+```math
+r_{d,t} \le \text{RequirementTimeSeriesParameter}_{t} \cdot \text{PF}\quad  \forall d\in \mathcal{D}_s, \forall t\in \{1,\dots, T\},
+```
+
+Finally, there is a restriction based on the reserve response time for the non-spinning reserve if the unit is off. To do so, compute ``R^\text{limit}_d`` as the reserve response limit as:
+```math
+R^\text{limit}_d = \begin{cases}
+0 & \text{ if TF } \le T^\text{st,up}_d \\
+P^\text{th,min}_d +  (\text{TF}_s - T^\text{st,up}_d) \cdot R^\text{th,up}_d \Delta T \cdot R^\text{th,up}_d & \text{ if TF } > T^\text{st,up}_d
+\end{cases}, \quad \forall d\in \mathcal{D}_s
+```
+
+Then, the constraint depends on the commitment variable ``u_t^\text{th}`` as:
+
+```math
+r_{d,t} \le (1 - u_{d,t}^\text{th}) \cdot R^\text{limit}_d
+```
+
+---
+
+## `ConstantMaxInterfaceFlow`
+
+This Service model only accepts the `PowerSystems.jl` `TransmissionInterface` type to properly function. It is used to model a collection of branches that make up an interface or corridor with a maximum transfer of power.
+
+```@docs
+ConstantMaxInterfaceFlow
+```
+
+**Variables**
+
+If slacks are used:
+- [`InterfaceFlowSlackUp`](@ref):
+    - Bounds: [0.0, ]
+    - Symbol: ``f^\text{sl,up}``
+- [`InterfaceFlowSlackDown`](@ref):
+    - Bounds: [0.0, ]
+    - Symbol: ``f^\text{sl,dn}``
+
+**Static Parameters**
+
+- ``F^\text{max}`` = `PowerSystems.get_active_power_flow_limits(service).max`
+- ``F^\text{min}`` = `PowerSystems.get_active_power_flow_limits(service).min`
+- ``C^\text{flow}`` = `PowerSystems.get_violation_penalty(service)`
+- ``\mathcal{M}_s`` = `PowerSystems.get_direction_mapping(service)`. Dictionary of contributing branches with its specified direction (``\text{Dir}_d = 1`` or ``\text{Dir}_d = -1``) with respect to the interface.
+
+**Relevant Methods**
+
+- ``\mathcal{D}_s`` = `PowerSystems.get_contributing_devices(system, service)`: Set (vector) of all contributing branches to the service ``s`` in the system.
+
+**Objective:**
+
+Add the violation penalty proportional cost to the objective function if slack variables are used ``+ (f^\text{sl,up} + f^\text{sl,dn}) \cdot C^\text{flow}``.
+
+**Expressions:**
+
+Creates the expression `InterfaceTotalFlow` to keep track of all `FlowActivePowerVariable` of contributing branches to the transmission interface.
+
+**Constraints:**
+
+It adds the constraint to limit the `InterfaceTotalFlow` by the specified bounds of the service ``s``:
+
+```math
+F^\text{min} \le f^\text{sl,up}_t - f^\text{sl,dn}_t + \sum_{d\in\mathcal{D}_s} \text{Dir}_d f_{d,t} \le F^\text{max}, \quad \forall t \in \{1,\dots,T\}
+```

+* *Service Formulation*: The model of a service that is incorporated into a large system optimization models. `Services` (or ancillary services) are models used to ensure that there is necessary support to the power grid from generators to consumers, in order to ensure reliable operation of the system. The most common application for ancillary services are reserves, i.e., generation (or load) that is not currently being used, but can be quickly made available in case of unexpected changes of grid conditions, for example a sudden loss of load or generation. A service model needs to follow some requirements to be integrated into operation problems. For more information about valid `ServiceModel`s and their mathematical representations, check out the [Formulation Library](@ref service_formulations).
+
 * *Simulation*: A simulation is a pre-determined sequence of decision problems in a way that solving it, resembles the solution procedures commonly used by operators. The most common simulation model is the solution of a Unit Commitment and Economic Dispatch sequence of problems.
 
 * *Solver*: A solver is a software package that incorporates algorithms for finding solutions to one or more classes of optimization problem. For example, FICO Xpress is a commercial optimization solver for linear programming (LP), convex quadratic programming (QP) problems, convex quadratically constrained quadratic programming (QCQP), second-order cone programming (SOCP) and their mixed integer counterparts. **A solver is required to be specified** in order to solve any computer optimization problem.

+# [FeedForward Formulations](@id ff_formulations)
+
+In PowerSimulations, chronologies define where information is flowing. There are two types
+of chronologies.
+
+- inter-stage chronologies: Define how information flows between stages. e.g. day-ahead solutions are used to inform economic dispatch problems
+- intra-stage chronologies: Define how information flows between multiple executions of a single stage. e.g. the dispatch setpoints of the first period of an economic dispatch problem are constrained by the ramping limits from setpoints in the final period of the previous problem.
+
+The definition of exactly what information is passed using the defined chronologies is accomplished using **FeedForwards**.
+
+Specifically, a FeedForward is used to define what to do with information being passed with an inter-stage chronology in a Simulation. The most common FeedForward is the `SemiContinuousFeedForward` that affects the semi-continuous range constraints of thermal generators in the economic dispatch problems based on the value of the (already solved) unit-commitment variables.
+
+The creation of a FeedForward requires at least to specify the `component_type` on which the FeedForward will be applied. The `source` variable specify which variable will be taken from the problem solved, for example the commitment variable of the thermal unit in the unit commitment problem. Finally, the `affected_values` specify which variables will be affected in the problem to be solved, for example the next economic dispatch problem.
+
+### Table of contents

+2. [`FixValueFeedforward`](#FixValueFeedforward)

+
+## `SemiContinuousFeedforward`
+
+```@docs
+SemiContinuousFeedforward
+```
+
+**Variables:**
+
+No variables are created
+
+**Parameters:**
+
+- ``\text{on}^\text{th}`` = `OnStatusParameter` obtained from the source variable, typically the commitment variable of the unit commitment problem ``u^\text{th}``.
+
+**Objective:**
+
+No changes to the objective function.
+
+**Expressions:**
+
+Adds ``-\text{on}^\text{th}P^\text{th,max}`` to the `ActivePowerRangeExpressionUB` expression and ``-\text{on}^\text{th}P^\text{th,min}`` to the `ActivePowerRangeExpressionLB` expression.
+
+**Constraints:**
+
+Limits the `ActivePowerRangeExpressionUB` and `ActivePowerRangeExpressionLB` by zero as:
+
+```math
+\begin{align*}
+&  \text{ActivePowerRangeExpressionUB}_t := p_t^\text{th} - \text{on}_t^\text{th}P^\text{th,max} \le 0, \quad  \forall t\in \{1, \dots, T\}  \\
+&  \text{ActivePowerRangeExpressionLB}_t := p_t^\text{th} - \text{on}_t^\text{th}P^\text{th,min} \ge 0, \quad  \forall t\in \{1, \dots, T\} 
+\end{align*}
+```
+
+Thus, if the commitment parameter is zero, the dispatch is limited to zero, forcing to turn off the generator without introducing binary variables in the economic dispatch problem.

-```
\ No newline at end of file

+
+## Changes on Expressions due to Service models
+
+It is important to note that by adding a service to a Optimization Problem, variables for each contributing device must be created. For example, for every contributing generator ``d \in \mathcal{D}`` that is participating in services ``s_1,s_2,s_3``, it is required to create three set of `ActivePowerReserveVariable` variables:
+
+```math
+r_{s_1,d,t},~ r_{s_2,d,t},~ r_{s_3,d,t},\quad \forall d \in \mathcal{D}, \forall t \in \{1,\dots, T\}
+```
+
+### Changes on UpperBound (UB) and LowerBound (LB) limits
+
+Each contributing generator ``d`` has active power limits that the reserve variables affect. In simple terms, the limits are implemented using expressions `ActivePowerRangeExpressionUB` and `ActivePowerRangeExpressionLB` as:
+
+```math
+\text{ActivePowerRangeExpressionUB}_t \le P^\text{max} \\
+\text{ActivePowerRangeExpressionLB}_t \ge P^\text{min}
+```
+`ReserveUp` type variables contribute to the upper bound expression, while `ReserveDown` variables contribute to the lower bound expressions. So if ``s_1,s_2`` are `ReserveUp` services, and ``s_3`` is a `ReserveDown` service, then for a thermal generator ``d`` using a `ThermalStandardDispatch`:
+
+```math
+\begin{align*}
+& p_{d,t}^\text{th} + r_{s_1,d,t} + r_{s_2,d,t} \le P^\text{th,max},\quad \forall d\in \mathcal{D}^\text{th}, \forall t \in \{1,\dots,T\} \\
+& p_{d,t}^\text{th} - r_{s_3,d,t} \ge P^\text{th,min},\quad \forall d\in \mathcal{D}^\text{th}, \forall t \in \{1,\dots,T\}
+\end{align*}
+```
+
+while for a renewable generator ``d`` using a `RenewableFullDispatch`:
+
+```math
+\begin{align*}
+& p_{d,t}^\text{re} + r_{s_1,d,t} + r_{s_2,d,t} \le \text{ActivePowerTimeSeriesParameter}_t,\quad \forall d\in \mathcal{D}^\text{re}, \forall t \in \{1,\dots,T\}\\
+& p_{d,t}^\text{re} - r_{s_3,d,t} \ge 0,\quad \forall d\in \mathcal{D}^\text{re}, \forall t \in \{1,\dots,T\}
+\end{align*}
+```
+
+### Changes in Ramp limits
+
+For the case of Ramp Limits (of formulation that model these limits), the reserve variables only affect the current time, and not the previous time. Then, for the same example as before:
+```math
+\begin{align*}
+& p_{d,t}^\text{th} + r_{s_1,d,t} + r_{s_2,d,t} - p_{d,t-1}^\text{th}\le R^\text{th,up},\quad \forall d\in \mathcal{D}^\text{th}, \forall t \in \{1,\dots,T\}\\
+& p_{d,t}^\text{th} - r_{s_3,d,t} - p_{d,t-1}^\text{th}  \ge -R^\text{th,dn},\quad \forall d\in \mathcal{D}^\text{th}, \forall t \in \{1,\dots,T\}
+\end{align*}
+```

 # [FeedForward Formulations](@id ff_formulations)
 
-In PowerSimulations, chronologies define where information is flowing. There are two types
-of chronologies.
+**FeedForwards** are the mechanism to define how information is shared between models. Specifically, a FeedForward defines what to do with information passed with an inter-stage chronology in a Simulation. The most common FeedForward is the `SemiContinuousFeedForward` that affects the semi-continuous range constraints of thermal generators in the economic dispatch problems based on the value of the (already solved) unit-commitment variables.
 
-- inter-stage chronologies: Define how information flows between stages. e.g. day-ahead solutions are used to inform economic dispatch problems
-- intra-stage chronologies: Define how information flows between multiple executions of a single stage. e.g. the dispatch setpoints of the first period of an economic dispatch problem are constrained by the ramping limits from setpoints in the final period of the previous problem.
-
-The definition of exactly what information is passed using the defined chronologies is accomplished using **FeedForwards**.

-The creation of a FeedForward requires at least to specify the `component_type` on which the FeedForward will be applied. The `source` variable specify which variable will be taken from the problem solved, for example the commitment variable of the thermal unit in the unit commitment problem. Finally, the `affected_values` specify which variables will be affected in the problem to be solved, for example the next economic dispatch problem.
