Based on the analysis of genetic algorithm and particle swarm optimization algorithm, the advantages of these two algorithms are analyzed. The genetic particle swarm optimization algorithm is given, The parameters of the wide area damping controller are optimized by genetic algorithm. A four-machine and two-zone interconnected power system with 150 MW doubly-fed wind farms is simulated. The simulation results show that the designed wide-area damping controller is effective.
