7 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 7

8 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 WTG.sav WTG generic_type3_1.dyd run_case.p WTG generic_type3_1.chf Vt Pg Qg.pdf Data Command file to run simulation Simulation results C:\upslf*\samples\WTG generic models\wtg Type 3\Case 1 8

10 Sample cases 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 10

15 repc_a power plant controller model # Regulate the to-bus (bus 4): #repc_a 5 "WTG TERM" "1 " 4 "WF LOW 2" : #1 / 15

17 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" "1 " : #1 mva=111. def Default parameters for regc_a only (for WTG type 3 & 4). 17

18 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) * wt1g 5 "WTG TERM " 0.60 "1 " : #1 mva= def wt1t 5 "WTG TERM " 0.60 "1 " : #1 def 18

19 Interactive addition WTG models (or other models) Use edds table to interactively add models 19

20 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 20
