Cases 1(a) & 2(a) will not impact the model's operations, and the target constraint will be rendered useless. In most cases that have no energy target and a non-zero value for $C^{value}$, if this cost is too high ($C^{value} >> 0$) or too low ($C^{value} <<0$) can result in either the model holding on to stored energy till the end of the model not storing any energy in the device. This is caused by the fact that when the energy target is zero, we have $E_t = - E^{shortage}_t$, and $- E^{shortage}_t * C^{value}$ in the objective function is replaced by $E_t * C^{value}$, thus resulting in $C^{value}$ to be seen as the cost of stored energy.

The use of reactive power variables and constraints will depend on the network model used, i.e., whether it uses (or does not use) reactive power. If the network model is purely active power-based, reactive power variables and related constraints are not created.

PowerSystems.Service Formulations

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.

Relevant Methods:

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:

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):

\[\text{ActivePowerRangeExpressionUB}_{t} = p_t^\text{th} + r_{s_1,t} + r_{s_2, t} \le P^\text{th,max}\]

similarly if $s_3$ is a ReserveDown service (e.g. Reg-Down):

\[\text{ActivePowerRangeExpressionLB}_{t} = p_t^\text{th} - r_{s_3,t} \ge P^\text{th,min}\]

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 $s$:

\[\sum_{d\in\mathcal{D}_s} r_{d,t} + r_t^\text{sl} \ge \text{Req},\quad \forall t\in \{1,\dots, T\} \quad \text{(for a ConstantReserve)} \\ \sum_{d\in\mathcal{D}_s} r_{d,t} + r_t^\text{sl} \ge \text{RequirementTimeSeriesParameter}_{t},\quad \forall t\in \{1,\dots, T\} \quad \text{(for a VariableReserve)}\]

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.

\[r_{d,t} \le \text{Req} \cdot \text{PF} ,\quad \forall d\in \mathcal{D}_s, \forall t\in \{1,\dots, T\} \quad \text{(for a ConstantReserve)} \\ -r_{d,t} \le \text{RequirementTimeSeriesParameter}_{t} \cdot \text{PF}\quad \forall d\in \mathcal{D}_s, \forall t\in \{1,\dots, T\}, \quad \text{(for a VariableReserve)}\]

StepwiseCostReserve

For each service $s$ of the model type ReserveDemandCurve the following variables are created:

Variables:

Time Series Parameters

For a ReserveDemandCurve PowerSystems type:

| Parameter | Default Time Series Name |

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:

The ServiceRequirementVariable is added as a piecewise linear cost based on the decreasing offers listed in the variable_cost time series. 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.

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):

\[\text{ActivePowerRangeExpressionUB}_{t} = p_t^\text{th} + r_{s_1,t} + r_{s_2, t} \le P^\text{th,max}\]

similarly if $s_3$ is a ReserveDown service (e.g. Reg-Down):

\[\text{ActivePowerRangeExpressionLB}_{t} = p_t^\text{th} - r_{s_3,t} \ge P^\text{th,min}\]

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 $s$:

\[\sum_{d\in\mathcal{D}_s} r_{d,t} \ge \text{req}_t,\quad \forall t\in \{1,\dots, T\} \]

GroupReserve

Service must be used with ConstantReserveGroup PowerSystems.jl type. This service model is used to model an aggregation of services.

For each service $s$ of the model type GroupReserve the following variables are created:

Variables:

No variables are created, but the services associated with the GroupReserve must have created variables.

  • $\text{Req}$ = PowerSystems.get_requirement(service)

Relevant Methods:

  • $\mathcal{S}_s$ = PowerSystems.get_contributing_services(system, service): Set (vector) of all contributing services to the group service $s$ in the system.
  • $\mathcal{D}_{s_i}$ = PowerSystems.get_contributing_devices(system, service_aux): Set (vector) of all contributing devices to the service $s_i$ in the system.

Objective:

Does not modify the objective function, besides the changes to the objective function due to the other services associated to the group service.

Expressions:

No changes, besides the changes to the expressions due to the other services associated to the group service.

Constraints:

A GroupReserve implements that the sum of all reserves of contributing devices, of all contributing services, must be larger than the GroupReserve requirement. Thus, for a GroupReserve service $s$:

\[\sum_{d\in\mathcal{D}_{s_i}} \sum_{i \in \mathcal{S}_s} r_{d,t} \ge \text{Req},\quad \forall t\in \{1,\dots, T\} \]

  • ReserveRequirementSlack:

    • Bounds: [0.0, ]
    • Default proportional cost: 1e5
    • Symbol: $r^\text{sl}$

RampReserve only accepts VariableReserve PowerSystems.jl type. With that, the parameters are:

\[\text{ActivePowerRangeExpressionUB}_{t} = p_t^\text{th} + r_{s_1,t} + r_{s_2, t} \le P^\text{th,max}\]

similarly if $s_3$ is a ReserveDown service (e.g. Reg-Down):

\[\text{ActivePowerRangeExpressionLB}_{t} = p_t^\text{th} - r_{s_3,t} \ge P^\text{th,min}\]

Constraints:

A RampReserve 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 $s$:

\[\sum_{d\in\mathcal{D}_s} r_{d,t} + r_t^\text{sl} \ge \text{RequirementTimeSeriesParameter}_{t},\quad \forall t\in \{1,\dots, T\}\]

Finally, there is a restriction based on the ramp limits of the contributing devices:

\[r_{d,t} \le R^\text{th,up} \cdot \text{TF}\quad \forall d\in \mathcal{D}_s, \forall t\in \{1,\dots, T\}, \quad \text{(for ReserveUp)} \\ -r_{d,t} \le R^\text{th,dn} \cdot \text{TF}\quad \forall d\in \mathcal{D}_s, \forall t\in \{1,\dots, T\}, \quad \text{(for ReserveDown)}\]

NonSpinningReserve

For each service $s$ of the model type NonSpinningReserve, the following variables are created:

similarly if $s_3$ is a ReserveDown service (e.g. Reg-Down):

\[\text{ActivePowerRangeExpressionLB}_{t} = p_t^\text{th} - r_{s_3,t} \ge P^\text{th,min}\]

Constraints:

A NonSpinningReserve implements three fundamental constraints. The first is that the sum of all reserves of contributing devices must be larger than the NonSpinningReserve requirement. Thus, for a service $s$:

\[\sum_{d\in\mathcal{D}_s} r_{d,t} + r_t^\text{sl} \ge \text{RequirementTimeSeriesParameter}_{t},\quad \forall t\in \{1,\dots, T\}\]

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.

\[r_{d,t} \le \text{RequirementTimeSeriesParameter}_{t} \cdot \text{PF}\quad \forall d\in \mathcal{D}_s, \forall t\in \{1,\dots, T\},\]

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:

\[R^\text{limit}_d = \begin{cases} +r_{d,t} \le \text{RequirementTimeSeriesParameter}_{t} \cdot \text{PF}\quad \forall d\in \mathcal{D}_s, \forall t\in \{1,\dots, T\}, \quad \text{(for a VariableReserve)}\]

Constraints:

A NonSpinningReserve implements three fundamental constraints. The first is that the sum of all reserves of contributing devices must be larger than the NonSpinningReserve requirement. Thus, for a service $s$:

\[\sum_{d\in\mathcal{D}_s} r_{d,t} + r_t^\text{sl} \ge \text{RequirementTimeSeriesParameter}_{t},\quad \forall t\in \{1,\dots, T\}\]

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.

\[r_{d,t} \le \text{RequirementTimeSeriesParameter}_{t} \cdot \text{PF}\quad \forall d\in \mathcal{D}_s, \forall t\in \{1,\dots, T\},\]

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:

\[R^\text{limit}_d = \begin{cases} 0 & \text{ if TF } \le T^\text{st,up}_d \\ P^\text{th,min}_d + (\text{TF}_s - T^\text{st,up}_d) \cdot R^\text{th,up}_d \Delta T \cdot R^\text{th,up}_d & \text{ if TF } > T^\text{st,up}_d -\end{cases}, \quad \forall d\in \mathcal{D}_s\]

Then, the constraint depends on the commitment variable $u_t^\text{th}$ as:

\[r_{d,t} \le (1 - u_{d,t}^\text{th}) \cdot R^\text{limit}_d, \quad \forall d \in \mathcal{D}_s, \forall t \in \{1,\dots, T\}\]

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:

\[r_{s_1,d,t},~ r_{s_2,d,t},~ r_{s_3,d,t},\quad \forall d \in \mathcal{D}, \forall t \in \{1,\dots, T\}\]

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:

\[\text{ActivePowerRangeExpressionUB}_t \le P^\text{max} \\ +\end{cases}, \quad \forall d\in \mathcal{D}_s\]

Then, the constraint depends on the commitment variable $u_t^\text{th}$ as:

\[r_{d,t} \le (1 - u_{d,t}^\text{th}) \cdot R^\text{limit}_d, \quad \forall d \in \mathcal{D}_s, \forall t \in \{1,\dots, T\}\]

\[\text{ActivePowerRangeExpressionUB}_t \le P^\text{max} \\ \text{ActivePowerRangeExpressionLB}_t \ge P^\text{min}\]

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:

\[\begin{align*} & p_{d,t}^\text{th} + r_{s_1,d,t} + r_{s_2,d,t} \le P^\text{th,max},\quad \forall d\in \mathcal{D}^\text{th}, \forall t \in \{1,\dots,T\} \\ & p_{d,t}^\text{th} - r_{s_3,d,t} \ge P^\text{th,min},\quad \forall d\in \mathcal{D}^\text{th}, \forall t \in \{1,\dots,T\} @@ -15,4 +15,4 @@ \end{align*}\]

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:

ThermalGen Formulations

Thermal generation formulations define the optimization models that describe thermal units mathematical model in different operational settings, such as economic dispatch and unit commitment.

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 page.

Note

The use of reactive power variables and constraints will depend on the network model used, i.e., whether it uses (or does not use) reactive power. If the network model is purely active power-based, reactive power variables and related constraints are not created.

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 section.

PowerSimulations.jl

Overview

PowerSimulations.jl is a power system operations simulation tool developed as a flexible and open source software for quasi-static power systems simulations including Production Cost Models. PowerSimulations.jl tackles the issues of developing a simulation model in a modular way providing tools for the formulation of decision models and emulation models that can be solved independently or in an interconnected fashion.

PowerSimulations.jl supports the workflows to develop simulations by separating the development of operations models and simulation models.

  • Operation Models: Optimization model used to find the solution of an operation problem.
  • Simulations Models: Defined the requirements to find solutions to a sequence of operation problems in a way that resembles the procedures followed by operators.

The most common Simulation Model is the solution of a Unit Commitment and Economic Dispatch sequence of problems. This model is used in commercial Production Cost Modeling tools, but it has a limited scope of analysis.

How the documentation is structured

PowerSimulations.jl documentation and code are organized according to the needs of different users depending on their skillset and requirements. In broad terms there are three categories:

  • Modeler: Users that want to solve an operations problem or run a simulation using the existing models in PowerSimulations.jl. For instance, answer questions about the change in operation costs in future fuel mixes. Check the formulations library page to choose a modeling strategy that fits your needs.

  • Model Developer: Users that want to develop custom models and workflows for the simulation of a power system operation. For instance, study the impacts of an stochastic optimization problem over a deterministic.

  • Code Base Developers: Users that want to add new core functionalities or fix bugs in the core capabilities of PowerSimulations.jl.

PowerSimulations.jl is an active project under development, and we welcome your feedback, suggestions, and bug reports.

Note: PowerSimulations.jl uses the data model implemented in PowerSystems.jl to construct optimization models. In most cases, you need to add PowerSystems.jl to your scripts.

Installation

The latest stable release of PowerSimulations can be installed using the Julia package manager with

] add PowerSimulations

For the current development version, "checkout" this package with

] add PowerSimulations#main

An appropriate optimization solver is required for running PowerSimulations models. Refer to JuMP.jl solver's page to select the most appropriate for the application of interest.

PowerSystems has been developed as part of the Scalable Integrated Infrastructure Planning (SIIP) initiative at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL).

Configuring the simulation logger

You can configure the logging level used by the simulation logger when you call build!(simulation). Here is an example that increases logging verbosity:

import Logging
 using PowerSimulations
 simulation = Simulation(...)
-build!(simulation; console_level = Logging.Info, file_level = Logging.Debug)

The log file will be located at <your-output-path>/<simulation-name>/<run-output-dir>/logs/simulation.log.

Solver logs

You can configure logging for the solver you use. Refer to the solver documentation. PowerSimulations does not redirect or intercept prints to stdout or stderr from other libraries.

Recorder events

PowerSimulations uses the InfrastructureSystems.Recorder to store simulation events in a log file. Refer to this link for more information.

  1. Follow the instructions at https://nrel.github.io/jade/tutorial.html to submit the jobs. The example below will configure Jade to run each partition on its own compute node. Depending on the compute and memory constraints of your simulation, you may be able to pack more jobs on each node.Adjust the walltime as necessary.

This is caused by the fact that when the energy target is zero, we have E_t = - E^shortage_t, and - E^shortage_t * C^value in the objective function is replaced by E_t * C^value, thus resulting in C^value to be seen as the cost of stored energy.","category":"page"},{"location":"formulation_library/General/","page":"General","title":"General","text":"Case Energy Target Energy Shortage Cost Energy Value / Energy Surplus cost Effect\nCase 1(a) hatE=0 C^penalty=0 C^value=0 no change\nCase 1(b) hatE=0 C^penalty=0 C^value0 penalty for storing energy\nCase 1(c) hatE=0 C^penalty0 C^value=0 no penalties or incentives applied\nCase 1(d) hatE=0 C^penalty=0 C^value0 incentive for storing energy\nCase 1(e) hatE=0 C^penalty0 C^value0 penalty for storing energy\nCase 1(f) hatE=0 C^penalty0 C^value0 incentive for storing energy\nCase 2(a) hatE0 C^penalty=0 C^value=0 no change\nCase 2(b) hatE0 C^penalty=0 C^value0 penalty on energy storage in excess of target\nCase 2(c) hatE0 C^penalty0 C^value=0 penalty on energy storage short of target\nCase 2(d) hatE0 C^penalty=0 C^value0 incentive on excess energy\nCase 2(e) hatE0 C^penalty0 C^value0 penalty on both excess/shortage of energy\nCase 2(f) hatE0 C^penalty0 C^value0 penalty for shortage, incentive for excess energy","category":"page"},{"location":"modeler_guide/logging/#Logging","page":"Logging","title":"Logging","text":"","category":"section"},{"location":"modeler_guide/logging/","page":"Logging","title":"Logging","text":"PowerSimulations.jl will output many log messages when building systems and running simulations.

This is caused by the fact that when the energy target is zero, we have E_t = - E^shortage_t, and - E^shortage_t * C^value in the objective function is replaced by E_t * C^value, thus resulting in C^value to be seen as the cost of stored energy.","category":"page"},{"location":"formulation_library/General/","page":"General","title":"General","text":"Case Energy Target Energy Shortage Cost Energy Value / Energy Surplus cost Effect\nCase 1(a) hatE=0 C^penalty=0 C^value=0 no change\nCase 1(b) hatE=0 C^penalty=0 C^value0 penalty for storing energy\nCase 1(c) hatE=0 C^penalty0 C^value=0 no penalties or incentives applied\nCase 1(d) hatE=0 C^penalty=0 C^value0 incentive for storing energy\nCase 1(e) hatE=0 C^penalty0 C^value0 penalty for storing energy\nCase 1(f) hatE=0 C^penalty0 C^value0 incentive for storing energy\nCase 2(a) hatE0 C^penalty=0 C^value=0 no change\nCase 2(b) hatE0 C^penalty=0 C^value0 penalty on energy storage in excess of target\nCase 2(c) hatE0 C^penalty0 C^value=0 penalty on energy storage short of target\nCase 2(d) hatE0 C^penalty=0 C^value0 incentive on excess energy\nCase 2(e) hatE0 C^penalty0 C^value0 penalty on both excess/shortage of energy\nCase 2(f) hatE0 C^penalty0 C^value0 penalty for shortage, incentive for excess energy","category":"page"},{"location":"modeler_guide/logging/#Logging","page":"Logging","title":"Logging","text":"","category":"section"},{"location":"modeler_guide/logging/","page":"Logging","title":"Logging","text":"PowerSimulations.jl will output many log messages when building systems and running simulations.
