I want to use an external energy source(could be Battery) to provide transient time power supply during interruption. Can you tell me how should I do and which model I should use here?
Need to know the procedure of using external energy source for certain time in a network
I have used the generator in the load flow with Pgen=0 , and wind Control mode as Q limits based on WPF with Power Factor 1, and with X source=9999
while for the dynamic model, I have used REGCAU1 for the generator model , RECCU1 for the electrical controller, and REPCAU1 for the plant controller.
While REPCAU1 is your most important model since it controls how the energy storage behave under changes in votlage and frequency.
Hi, I find that you set the wind control mode as Q limits based on WPF with Power factor 1. Is it ok to set wind control mode as reactive power limits are specified by QT and QB?
Model the energy storage as a generator in load flow with Pgen=0. Use dynamic model CBEST and change VAR(L) to a proper value during the simulation when you want power supply from the storage. I.e. you control the power with VAR(L).
Thanks for ur guideline. I think it will work but i when i tried by writing the following code psspy.change_plmod_var(ibus=10, id='1', name='CBEST', j=1, rdata=85) output won't come as 85 MW rather it gives 15 MW. Could you please help me with the code? Thanks Sazzad
What data have you given to the generator in load flow and the CBEST model?
for gen----10,'1 ', 0.0 -10.860, 300.000, -300.000,1.02500, 0, 280.000, 1.00000E-4, 2.10000E-1, 0.00000E+0, 0.00000E+0,1.00000,1, 100.0, 270.000, 10.000, 1,1.0000 for CBEST model 10 'CBEST' 1 5.89 0.05 0.60 0.05 2.35 0.47 1.68 1.61 0.23206 0.32 0.21 0.1536 1.01 1.
For CBEST model i have used default data
It will work if you update CBEST parameter IACMAX to 1 and Vmin to -0.21.
