A PSO-Based Static Synchronous Compensator Controller for Power System Stability Enhancement

Abstract

In this paper Power system stability enhancement through static synchronous compensator (STATCOM)<br />based controller is investigated. The potential of the STATCOM supplementary controllers to enhance the<br />dynamic stability is evaluated. The design problem of STATCOM based damping controller is formulated<br />as an optimization problem according to the eigenvalue based objective function that is solved by a particle<br />swarm optimization (PSO) algorithm. The controllers are tuned to simultaneously shift the lightly damped<br />and un-damped electro-mechanical modes of machine to a prescribed zone in the s-plane. The results<br />analysis reveals that the designed PSO based STATCOM damping controller has an excellent capability in<br />damping the power system low frequency oscillations and enhance greatly the dynamic stability of the<br />power system.
