摘　　要：提出了基于杂交粒子群优化算法的分布式可再生能源并网的无功优化算法,从网损和静态电压稳定裕度两个角度出发,构建了含分布式发电系统的配电网无功优化的数学模型。在美国PG&E 69节点配电系统上进行效验。结果表明,该算法收敛性好、精度高;分布式电源并网后能有效降低系统的有功网损,提高电压稳定性,对分布式电源并网运行具有一定的参考价值。Reactive power optimization algorithm in network with distributed renewable energy based on hybrid particle swarm algorithm is proposed in this paper. Power loss and static voltage stability margin are taken into consideration, reactive power opti- mization mathematical model including distributed power generation system is constructed. Hybrid particle swarm algorithm applied for optimal reactive power is evaluated on an American PG＆E 69-bus power system. It is shown that the proposed approach converges to better convergence and precision. Distributed generation resources can effectively reduce the power loss and improve voltage stability. The research provides a reference value for the grid-connected operation of distributed generation resources.
