摘　　要：需求响应的实施改变了用户的用电习惯,同时分布式电源的出力和电动汽车的充电特性具有不确定性,这些因素对配电网重构提出了新的要求。为此,文中计及峰谷分时电价对用电负荷的影响,建立了综合考虑光伏发电系统、风力发电系统出力和电动汽车充电不确定性的配电网重构模型,采用量子进化算法,以运行费用最小为目标函数,对模型进行分时段求解。IEEE 33节点系统测试结果表明,所述方法能够有效计及分布式电源出力等不确定因素和需求响应因素对配电网重构的影响,较好地提高了配电网的运行经济性。The change of electricity using habits of users due to the implementation of demand response,along with the uncertainties of distributed powers output and electric vehicles（EVs）charging has posed new challenges for the distribution network reconfiguration.By referring to the impact of time-of-use（TOU）on the electricity load,a distribution network reconfiguration model with the uncertainties of the solar photovoltaic system,wind power output and EV charging taken into account is developed.Then the quantum evolutionary algorithm is used to solve the model in sub-periods.Finally,the test results on an IEEE 33-bus system show that the proposed approach can effectively improve the operating economy of distribution network by considering the influence of uncertainties of the output of distributed power systems and demand response on the distribution network reconfiguration.
