| 摘 要： | 将粒子群优化算法(PSO)应用到电力系统无功优化问题的研究中,给出了具体的实施流程。为提高PSO的搜索能力,对PSO进行了改进,在算法中加入了第 3种极值指导粒子搜索方向,并引入了“飞回”策略。对IEEE-30节点系统的仿真计算结果表明了算法的有效性。

| Abstract: | The particle swarm optimization algorithm (PSO) applied to reactive power optimization in power system is introduced in the paper, and the detailed implementing procedure is presented. To improve the search efficiency of PSO, a third extreme is inserted to the iteration formula to indicate the search direction and a "fly back" strategy is proposed. Simulation results of IEEE-30-bus power system show the efficiency of PSO compared with other optimization methods. |
