摘　　要：随着电动汽车用户数量的增加,研究电动汽车差异化行为特性对高比例新能源配电网的影响具有重要意义。通过蒙特卡洛法对电动私家车负荷特性进行建模,同时提出电动公交车在3种差异化行为特性、补能模式下的负荷特性模型;以网损和充换电站成本最小、光伏消纳最大为目标,建立了含分布式电源以及不同种类电动汽车充换电站的配电网协同规划模型,采用yalmip工具箱结合cplex求解器进行求解,旨在规划差异化电动汽车充换电站容量以解决电动汽车类型比例不同时的规划问题。最后,通过改进的IEEE 33节点配电系统算例验证了所提模型的有效性。With the increasing of electric vehicle users,it is of great significance to study the impact of differentiated behavior characteristics of electric vehicles on high proportion new energy distribution networks.The load characteristics of electric private cars are modeled using Monte Carlo method,and the load characteristic models for electric buses are proposed under three differentiated behavioral characteristics and energy replenishment modes.A collaborative planning model for distribution networks with distributed power sources and different types of electric vehicle charging and swapping stations is established with the goal of minimizing network loss and charging and swapping station costs,maximizing photovoltaic consumption.The yalmip toolbox and cplex solver are used to solve the problem,aiming to plan the capacity of differentiated electric vehicle charging and swapping stations to solve the planning problem when the proportion of electric vehicle types is different.Finally,the effectiveness of the proposed model is verified through an example of an improved IEEE33 node distribution system.
