I have created a code to build the Y matrix. The problem is that I've noticed that the funtion outputYmatrix does not calculate the Y in all nodes in my case... someone knows why?

import numpy as np import pandas as pd import sqlite3 import re import psse35 import psspy import pssarrays

psspy.psseinit()

_i = psspy.getdefaultint() _f = psspy.getdefaultreal() _s = psspy.getdefaultchar()

psspy.case(r'CASE.sav')

psspy.outputymatrix(i,i,_i,0,r'outYmatrix.txt') f = open(r'outYmatrix.txt') listaY = [] for lines in f: if lines.startswith(' ZERO') or not lines.strip(): break else: listaY.append(re.split('[,\n]',lines))

conn = sqlite3.connect(':memory:') cursor = conn.cursor() cursor.execute('CREATE TABLE YMATRIX (IBUS INT, JBUS INT, Yreal real, Yimag real)') conn.commit() [cursor.execute(f'INSERT INTO YMATRIX VALUES ({item[0]},{item[1]},{item[2]},{item[3]})')for item in listaY]

df = pd.readsql('SELECT * FROM YMATRIX ORDER BY IBUS, JBUS',conn).setindex('IBUS') df['Y'] = df.Yreal + 1j*df.Yimag df = df.astype({'Y':str}) df2 = df.resetindex().groupby([df.index, 'JBUS'])['Y'].aggregate('first').unstack().fillna('(0+0j)') Ymatrix=df2.tonumpy(complex)

print(Ymatrix.shape) print(Ymatrix)
