Stabilisateurs synergétiques des systèmes de puissance

Abstract

A new particle swarm optimized robust fuzzy indirect adaptive power system stabilizer is developed based on recently developed synergetic control methodology. Fuzzy systems are used in an adaptive scheme to approximate power system dynamics using a nonlinear model while synergetic control provides for rapid power system oscillations improving therefore transient system stability. Furthermore controller parameters are optimized using a PSO approach to further improve performances. Simulation of severe power system operating conditions is conducted to validate the proposed approach effectiveness while stability is guaranteed via Lyapounov synthesis.
