3.2. Initialisation Functions

The following standard initialisation functions are available in the controllers module of PYPOWER-Dynamics (listed in alphabetical order):

• CONST
• MULT
• SUM

CONST

Constant value:

Signal/State = Signal_Name = CONST(Value)

Initialises the signal or state variable to a constant scalar Value.

MULT

Multiplier function:

Signal/State = Signal_Name = MULT(Signal_1, Signal_2, ... , Signal_n)

Multiplies an arbitrary number of input signals, i.e. yo = yi1 * yi2 * ... * yin. Input signals can be negative to multiply negative inputs, e.g. SIGNAL = N3 = MULT(N1,-N2) is equivalent to initialising signal N3 = N1 * (-N2).

SUM

Summing function:

Signal/State = Signal_Name = SUM(Signal_1, Signal_2, ... , Signal_n)

Sums (or subtracts) an arbitrary number of input signals, i.e. yo = yi1 + yi2 + ... + yin. Input signals can be negative for subtraction, e.g. SIGNAL = N3 = SUM(N1,-N2) is equivalent to initialising signal N3 = N1 - N2.
