This is the general program for solution, it has 4 test cases (the 5, 6 , 9 and 14 IEEE bus systems) but can be accurately used in other power systems, just enter the data in tables , e.g(line & bus). The program computhes the admittance matrix Ybus and computes V and Theta using the Gauss Seidel method, then, the load flows are calculated. At the end, the program will give you a report about the states (V, Theta) and the computed power flows.
