Adaptive PSO Based Tuning of PID- Fuzzy and SVC-PI Controllers for Dynamic Stability Enhancement: A Comparative Analysis

The power system is a dynamic system. Satisfactory damping of power oscillations is an important concern when dealing with the rotor angle stability. To improve the damping of oscillations in power systems, supplementary control laws can be applied to existing devices. In this paper, a PID fuzzy controller structure and optimal PI controller of a static Var compensator (SVC) are presented and implemented on single machine infinite bus system for improving the oscillations damping. The parameters of both the PID fuzzy controller and SVC-PI controllers are tuned by the adaptive particle swarm optimization (APSO).
