摘　　要：电动汽车(plug-in electric vehicle,PEV)的大规模接入使得传统配电网的规划方法和模式发生了变化。为此,提出了一种计及PEV负荷的智能配电系统多阶段规划模型及其求解方法。首先,在考虑PEV负荷接入和系统规划可靠性指标要求的条件下,以配电网建设和运行成本最小化为目标,构建了包含变电站、分布式电源(distributed generation, DG)和线路在内的智能配电系统多阶段规划模型;其次,在考虑系统充裕度要求和经济性要求的条件下,提出了一种新的多阶段规划模型求解方法,通过模型简化和倒序运算,实现了智能配电系统多阶段规划模型的快速求解;最后,通过算例验证了所提模型及求解方法的可行性,并且分析了PEV渗透率和充电模式对智能配电网规划结果的影响。The increasing permeation of plug-in electric vehicles (PEVs) has changed the planning method and mode of traditional distribution network. For this reason, this paper proposed a multi-stage planning model and its solution method for intelligent power distribution system, with PEV load considered. Firstly, with PEV load and system planning reliability requirement considered, the model covered substation, distributed generation (DG) and feeder in the intelligent power distribution system, aiming to minimize the cost of system construction and operation. Then, considering system abundance and economic requirements, this paper provided a back-propagation solution method, which realizes fast solution of multi-stage planning through model simplification and back-propagation operation. Finally, this paper verified the feasibility of the proposed model and solution method by numerical examples, and analyzed the influence of PEV permeability and charging mode on the planning results of intelligent distribution network.
