Hello everyone: I want to get the VARS parameter by python after simulation, I've tried to use "psspy.mdlind" but it only can used in traditional machine, not in renewable energy. Can someone tell me how to get REPC model's parameter?

Sincerely, Thanks.

Use API psspy.windmind. See API manaul.

Could I ask what is "Starting VAR index" in this python function? Can I get each second's VARs value?

The API returns the index of the first VAR of the model. After simulation, you can only get the actual value of the VAR, i.e. the value at the end of the simulation.

So, if I add a fault in 1 sec, and clear fault in 0.2sec, final run to 20 sec, I can just get 1 sec's VARs, 1.2sec's VARs, and 20 sec's VARs, is it correct?Can I use "psspy.var_channel" to get the actual value of the VARs?

I've try to use "psspy.var_channel" to get the VARs value. First, I use "psspy.windmind" to get first VAR of the model. Then, I use "psspy.var_channel(status, ident)" to get the VARs value.

Which "status" I just key in the first VAR of the model that I've got by "psspy.windmind", and the "ident" I just key in a space, like ' '. The result of PSS/E just print "Invalid VAR index: <omitted value="">; value must be in the range 1 through 250000 (002502)".
