The invention discloses a planning method and device for an electric vehicle charging station, and the method comprises the following steps: obtaining a network frame structure, line parameters and historical loads of a regional power distribution network, and calculating initial candidate nodes of the charging station; correcting the initial candidate nodes of the charging station according to the road network structure to obtain corrected candidate nodes; and the corrected candidate nodes are optimized, and the node to which the maximum value of the comprehensive evaluation index belongs is the optimal arrangement node of the charging station. According to the method, the load limit values of the candidate nodes in the power distribution network are obtained through load flow calculation, sorting is carried out according to the sizes of the load limit values, the initial candidate node sequence is obtained, the initial candidate nodes are corrected through a road network structure and comprehensive evaluation indexes considering safety and economy, and the most ideal charging station layout position is obtained. The method gives consideration to safety and economic operation of the power distribution network, road network constraint and the like, and can fully consider the rationality of the position of the charging station.
本发明公开一种电动汽车充电站的规划方法和装置,包括以下步骤:获取区域配电网网架结构、线路参数以及历史负荷,并计算充电站初始候选节点;根据路网结构对充电站初始候选节点进行修正,得到修正后的候选节点;对修正后的候选节点优化,综合评估指标的最大值所属的节点为充电站最优布置节点。本发明通过潮流计算得出配电网中各候选节点的负荷限值,并按其大小进行排序,得到初始候选节点次序,通过路网结构、计及安全与经济性的综合评估指标对初始候选节点进行修正,得到最理想的充电站布局位置。本方法兼顾了配电网安全以及经济运行、路网约束等,并且能够充分考虑充电站位置的合理性。
