I am an undergraduate doing a research project on BESS. i used a generator as a conventional machine and used the cbest model with below parameters,

1       PMAX (pu on MBASE)
1.1     OutEff (>= 1) Output Efficiency                                 
0.9     InpEff (<= 1) Input Efficiency                                                                  
1.2     IACMAX (pu)
100     KAVR, AVR gain
0       T1, AVR time constant (sec)
1       T2, AVR time constant (sec)
0.05    T3, AVR time constant (sec) ( >0 )
10      T4, AVR time constant (sec)
1       VMAX, AVR speed limit (pu)
-1      VMIN, AVR speed limit (pu) ( <0 )
0.025   DROOP (pu)

Is it enough to model the bess or do i need to select a model for exciter, governor, stabilizer,..

No other model is needed. The only possible auxiliary models are a stabiliser which will modulate VOTHSG or a compensator model to change the measured voltage.

The active power output is changed manually in the simulation with VAR(L).

Thank you for replying. I'm targeting to achieve frequency regulation with a BESS. Is the cbest model is the only model which i can use for BESS or are there other models too.
