Load flow analysis in power system network incorporating statcom: A comparison of the direct and indirect algorithm of the newton- raphson method

Abstract

This paper presents load flow analysis and the mathematical steady-state modeling of Static Synchronous Compensator (STATCOM) to study its effect on the power system network. More precisely, we propose a new approach method so-called direct algorithm and then compare it with the indirect algorithm in testing cases: IEEE 5-bus, IEEE 14-bus, and IEEE 30-bus systems. We compare the accuracy, the number of iterations and the computational time. The simulation results show that the direct algorithm is effective in terms of accuracy, speed of computation and various practical applications.
