my question is about Python with Psse
I should run the playback model in Psse, but I can not. At first, I add the playback model like below: (psspy.addmodellibrary('path\plbvfu1_v33.dll')) in command window of the psse. But, I got the INVALID ACTIVITY error. I don't know anything about the python. is it important for working with psse? Thank you.
