摘　　要：随着电动汽车的出现和普及,未来电动汽车充电站作为电力系统的最新负荷,将给电力系统稳定和电力系统需求侧管理带来挑战。针对可双向供电的电动汽车作为电网重要负荷建模,利用数学模型模拟出电动汽车充电与放电时对电力系统的影响。同时以辽宁某运行电动车项目的实际情况进行实验,发现电动汽车入网对中低压配电网的潮流及相关的变压设备具有不同程度的影响。通过理论建模分析结合实际相关测试,提出了电动车对电网潮流及设备的影响规律,为电力系统接纳新能源用电负荷稳定运行提供了重要参考。With the emergence and popularity of the electric car,the future electric car charging stations as the latest load of power system,will bring challenges to power system stability,power system,demand side management. This paper points at tw o- way power supply of the electric car as an important load modeling of the grid,using mathematical model to simulate the electric car charging and discharging effect for power system.At the same time,we make a experiment of running electric vehicle project with the actual situation in Liaoning,and found that the electric car access have different degree of influence of low voltage distribution netw ork and the1 related trends in pressure equipment with. This article combined with the actual tests through the theoretical modeling analysis,put forw ard the trends of electric vehicles for the grid and equipment,and provides an important reference for the acceptance of new energy power load in power system stable operation.
