A genetic algorithm PSS and AVR controller for electrical power system stability

In this paper genetic algorithm (GA) is applied in order to design a PSS/AVR controllers with the goal of improving both transient stability and voltage regulation of power system under a symmetrical three-phase short circuit fault. A comparison based on simulation is then performed between the proposed approach and the classical controllers (manual control, AVR with no PSS, AVR with PSS). The simulation results with a Single Machine Infinite Bus (SMIB) demonstrate the effectiveness of the proposed approach.
