Hi, am trying to model a battery storage to provide primary frequency response in PSSE using CBEST model but am unable to observe any dynamic changes in its output. Will appreciate if i can get some direction.

Model CBESTdoesn't have frequency control loop itself. Pout will be kept constant by the model. The power may be changed either manually or automatically by a separate model.

You can change Pout manually during the simulation by updating VAR(L).

For automatic primary frequency control you need to add a model updating VAR(L) of CBEST, as @Yunzhi Cheng wrote.

You need to add another model to attach to CBEST to change Pref.
