Hi, I have a code and in every step I should run the psse. So, I want to decrease the time for running. There is any technique for reducing the psse running time? My code is for 3 buses with two generators and it take 3-4 seconds for running. I run my code for 25 seconds. I don't know something that are in my code. For example, I don't know meaning of this: psspy.psseinit(150000) and I don't know its difference with psspy.psseinit(200). Thank you so much.

This is a question about code optimisation. No one can really help without the full code.

The psspy.psseinit() API initializes an instance of PSSE with the number of buses shown in the parenthesis. So psspy.psseinit(150000) reserves enough memory for a 150,000 bus case. On the other hand, psspy.psseinit(200) only reserves enough memory for a 200 bus case. You can read more about the bus size limits in Section 3.3.1 of the PSSE v33 Program Operation Manual.

I would assume psspy.psseinit(200) would run marginally faster than psspy.psseinit(150000), but that's just a hunch. You'd have to test that for yourself.
