New Intelligent AVR Controller Based on Particle Swarm Optimization for Transient Stability Enhancement

摘要

In this work, we present a new intelligent control scheme to enhance the transient stability of multi-machine power system based on the generator automatic voltage regulation system. The algorithm consists on the estimation of the best parameters of voltage regulators to minimize an objective function. Particle swarm optimization and genetic algorithm methods are used to get the best performance of regulation systems. The control performances damp significantly oscillations and improve the stability of the system after a given disturbance which enhance the transient stability and obtain a new improved critical clearing time (CCT). The results are very promising and could be validated in practice.
