How to modulate the governor or exciter of generator in PSS/E for dynamic simulation?
I am kind of new in PSS/E but here is my question:
I have a single machine infinite-bus, how can I modulate the governor or exciter of machine with a sin wave when I am doing dynamic simulation?
I found out that change_gref can change the value of the element of the GREF (governor reference). But I am not sure if I can use it to modulate the governor with sin wave.
Here is my python script:
