DESIGN OF H∞ STABILIZER FOR POWER SYSTEM BASED ON GA-PSO ALGORITHM

Zhao Jule, Han Guangxin

ABSTRACT:Power system stabilizer (PSS) mainly adjusts the phase of power system and damping compensation by parameter tuning. If the operation point of power system changes, the traditional PSS can’t guarantee the robustness of power system. In this paper, a H∞ stabilizer is designed for the power system, in which the weighting function is optimized by the genetic particle swarm optimization (GA-PSO). Simulation results validate the robustness of the GA-PSO H∞ stabilizer of power system.
