| Abstract: |
| PSO(Particle Swarm Optimization) algorithm is applied to optimize the unit commit-ment of power system. With the principle introduced,the influence of PSO parameter setting on its searching capability and convergence speed is analyzed and then validated by usual test functions. Corresponding mathematic model is built up and used in a three - machine six - bus IEEE power system simulation. Compared with genetic algorithm and chaotic optimization,PSO is better in algorithmic structure,computing time,search area control,convergence speed and so on. The application is effective. |
