摘要
依据电动汽车用户行驶习惯的概率分布特性,建立了私家车两个时段规模化电动汽车充电负荷模型,进而分析了电动汽车随机充电对配电网产生的影响。以IEEE 33节点配电系统为模型,在不同渗透率下,讨论了电动汽车的随机充电对主动配电网产生的影响。仿真结果表明,随着电动汽车渗透率的增大,电动汽车随机充电对配电网的安全、经济运行影响增大。
According to the probability distribution characteristics of electric vehicles users' driving habits,the two time scale of privates' electric vehicle charging load model was presented,then the influence of electric vehicles with the disordered charging on distribution network was analyzed. An IEEE33-node distribution system was tested as a model. In different permeability,the influence of the random charging of electric vehicle to the active distribution network was studied. The results show that the increasing of the permeability of electric vehicles has more negative influence on the safety and economic operation of distribution network.
