Hello, community!

I am building some automation Python script and I need to change the MW output of the machine during time-domain simulation. I know I need to use the psspy.change_gref() API to do that. But the problem is that I do not know what is the initial GREF value so I could scale it properly in order to get the desired MW output. The initial GREF value depends on various governor parameters, such as the droop R value. Hence, I am searching for an API that can get me the initial GREF.

I found that I can read it as a VAR variable, but every governor model has different vars, so this is not practical at all.

Does anyone know an API that can readily provide what is the current GREF value?

Thanks! Nikolay
