摘　　要：为了降低网损,对充换电站的电气接入点和接入工作功率进行了研究,分析了单个和多个充换电站接入配电系统不同电气节点产生的有功损耗的变化规律。针对多个未知运行状态的充换电站接入配电系统某些固定电气节点的情况,提出了一种基于试验设计的电网有功损耗快速估算方法,其能够在准确反映建模所需信息的同时大幅缩减仿真试验次数。以降低有功损耗为目标,对估算所得的模型进行组合优化。In order to reduce the power loss,the electric connected nodes and operation power of charging and swap- ping stations are investigated, and the variation law of the active power loss caused by different electric nodes con- nected with single or multiple charging and swapping stations is analyzed. In view of the fact that a number of stations with unknown operating state are connected to some fixed electric nodes in the distribution system, a fast estimation method of power loss based on DOE（ Design Of Experiment） is proposed, which can not only accurately describe the modeling information, but also significantly reduce the number of simulation tests. A hybrid optimization approach that aims to minimize the power loss is proposed for the estimated charging and swapping station model.
