Modeling a WTG or PV plant in PSLF

Need the customary two files: *.sav and *.dyd files read *.sav file read *.dyd file initialize run May want to have an additional *.dyd file with only WTG data of interest

read *.sav file read *.dyd file 1 read *.dyd file 2 initialize run Can always edit and existing dyd file to add a new plant


Sample cases in PSLF

Sample cases included in c:\upslf*\samples\WTG generic models may serve as an initial point toward setting up a wind power plant model

Use as is or with minor modifications to simulate a SMIB system

Copy data into an existing dyd file Use WTG data in a separate dyd file to be used in conjunction with other dyd file

Inclusion of WTG models in dyd file

Invoke models using the “def” option in the dyd file (this loads default values when the dyd is read) *

regc_a 5 "WTG TERM" 0.600 "1 " : #1 mva=111. def

• “Default” parameters for regc_a only (for WTG type 3 & 4).

Interactive addition WTG models (or other models)

Use edds table to interactively add models


Modeling a WTG or PV plant in PSLF

To run a simulation with a wind or photovoltaic plant, only the generator/converter model, regc_a, is required. Of course, the dynamic functionality of the plant would be absent in this case, but: May want to build a given plant incrementally beginning with only regc_a If having initialization problems or other issues where a given

wind plant is suspect: turn off all plant components except regc_a to isolate problem
