Powerflow (Newton Raphson)

version (7.09 KB) by Orlando Ramirez Barron
The algorithm gets the states (V and Theta) of the electric power system and power flows

The algorithm uses the newton raphson method to obtain the states of the system and also the power injection and flows using the Jacobian matrix (partial derivates of V and Theta). The program has two menus, one to choose the power system to analyze, and another one to show the solutions.

Sir can I get code for three phase newton raphson/backward forward sweep load flow analysis code?

The new version includes more test cases and assumes that the swing bus is bus # 1.
