hi everyone, I'm trying to add a CBEST model in my system,during the dynamics simulation here is the imformation from output bar,could someone help me understand how to resolve it,thanks.


  I   DSTATE(I)    STATE(I)     MODEL             STATE     BUS# X-- NAME --X BASKV  ID
 6460    1.1000       0.0000      CBEST              K+3       2       ESSG   22.800  1

It is better to show the load flow data for the generator and the dynamic data for CBEST.

thanks your reply,here is the dynamics data I set.And the load flow data I only set Pgen into 100MW others parameter I use the default value.

check the limits on that model. that state variable is exceeding some limit in the model
