摘要
为研究分布式电源接入对配网的影响,建立了包含发电收益最优、有功耗损最低和电压稳定度的多目标优化模型,并运用改进的微分进化算法对接入配网的分布式电源进行整体寻优,该算法将自适应策略融入到传统微分进化算法中,并结合Pareto占优概念将所有代非占优解存储到外部精英存档中。通过对IEEE-33节点的标准配电网算例分析,表明分布式电源的合理配置可使配网电压水平提升、减小有功网损、提升电压稳定指标,且所提模型和算法合理、可行。
Considering the influences of distributed generation on the distribution network,we set up a multi-objective optimization model in terms of power generation benefits,energy loss and voltage stability.An adaptive strategy was added into the traditional differential evolution algorithm.At the same time,we can store dominant elite solutions of all generations into external elite archiving with the Pareto dominant concept.Then improved optimization strategy was used to optimize distributed generation connected to the distribution network.Through analysis of standard IEEE-33 node cases of the distribution network,it shows that optimal configuration of distributed generation can improve voltage level,reduce energy loss and promote voltage stability index.The results verify the rationality of the proposed model and algorithm.
