Question about modeling BESS system
Hi, I am modeling an BESS and with one load and one normal generator, the dynamic parameter of BESS is from jconto's example(using REECCU1 and REGCA1), the others parameter are as below:
//Generator
1,'GENROU',1 6.00 0.05 0.535 0.05 3.33 0.67 1.72 1.66 0.23 0.37 0.21 0.10 1.01 1.02 /
//Exciter

// governor

2,'USRMDL',1,'REECCU1',102,0,5,45,7,6, 0,0,1,0,0, -99.0,99.0,0.0,-0.05,0.05,0.0,1.05,-1.05,0.0,0.05, 0.436,-0.436,1.1,0.9,0.0,0.1,0.0,40.0, 0.02,99.0,-99.0,1.0,0.0,1.82, 0.02,0.0,0.0,0.0,0.0,0.0, 0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0, 100.0,1.0,1.0,0.0, / Electrical Control Model for Utility Scale Battery Energy Storage
The problem I have is as follow:
1.How to adjust the machine parameter used in dynamic simulation? Before adding the exciter the non-disturbance simulation will get flat lines for the monitored variables, but after adding the exciter the initial condition is never OK, and the error message is about state K+2, means the output of the exciter maybe? How could I fix it? (I am also trying to use it in IEEE 9bus system, but the exciter have the same problem also.)
2.If I am going to use the BESS to introduce the active power, is there any difference between (1)changing the Paux in VAR of REECCU and (2) use the plant controller to control active power.
3.If the plant controller is needed, Is there any example or parameter for the plant controller REPCA1, I have tried the parameter in jconto's SMIB_BESS but it seems to have some initial condition problem, or do I mess up some thing?
I am new to PSS/E and python, but any suggestion will be much appreciate!

Thanks for jconto's suggestion it really helps to understand and just to update how I solve the initial condition problem, in my case I have changed the VRMAX and VRMIN for the exciter IEEET1, and also changed the Xd'' to same value in Xsource in the generator GENROU I used, then the initial condition suspect is no longer exist, hope someone who encounter the same problem can solve it also.
