电动汽车是汽车行业未来的发展方向,充电站作为电动汽车的配套服务设施,其建设也在积极进行.通过仿真分析了基于PWM整流+DC/DC变换器拓扑的单台充电机负荷特性,得到其负荷特性数学模型.基于该负荷特性利用数学模型进行分析,对影响充电站负荷的多种随机性因素分别进行了概率建模.在此基础上,利用蒙特卡罗建模方法,综合考虑了充电站负荷的各种随机性因素影响,得到了反应充电站时变性的静态负荷模型并给出了其不同渗透率情况下的日负荷曲线.%The electric vehicle is the future direction of the automotive industry. As the ancillary service facility of electric vehicles, the development of charging station is rapid. Through simulation analysis of single charger's load characteristic based on PWM rectifier + DC / DC converter topology, its mathematical model is obtained. Based on the load characteristics and using the mathematical model, probabilistic modeling of a variety of random factors affecting the charging station loads is carried out respectively. On this basis, using Monte Carlo modeling methods, comprehensively considering the influence of various random factors of charging station load, the static load model reflecting the charging station time-varying characteristics is got and the daily load curves under different permeability are given.
