Here is my script, not sure why it is not picking up the model.

import time

import psse34

import os,sys

import psspy

import redirect

import glob

import numpy as np

import pandas as pd

timestr = time.strftime("%Y%m%d_%H%M%S")

base_dir = 'C:\Users\Desktop\Load flow'

input_files_dir = 'C:\Users\Load flow\02_sav_case'

output_files_dir = 'C:\Users\Load flow\03_Results'


cwd = os.getcwd()

print ('\nScript running in the working directory:\n%s' % cwd)


_i=psspy.getdefaultint()

_f=psspy.getdefaultreal()

_s=psspy.getdefaultchar()

redirect.psse2py()

psspy.psseinit(80000)


os.chdir(base_dir)

case_name = ['RProponent model)_max_VRR_v1.sav']

suffix = ['High_Load']
