Is there any method to change the generator power output during a dynamic simulation?

For ex: Pout initial = 600 MW, Pout after disturbance = 400 MW

I tried CHANGE_GREF function and INCREMENT_GREF functions. But I do not see any change happened for the power output in the plots.

I assume you have a governor model connected to the generator!?

Yes, WSIEG1 model

Can you show the data for the model?

Change_gref looks like it should work. You could check the associated VAR L+0="referece" to see if it has been changed by your command. And maybe look at the other VARs while you are at it; the change should ripple through the controller to its output. Dave Hodson, Dynamica
