摘要
电动汽车的大规模发展对电网来说可谓机遇与挑战并存,无序充电将对电网带来冲击,智能充电则能优化电网的运行。分析不同类型电动汽车的充电行为,通过建立即插即充、夜间充电、智能充电等充电模式下各类电动汽车负荷模型,分析不同充电模式对区域电网负荷特性的影响。结果表明,合理利用电动汽车负荷和储能特性将有助于降低电网最大负荷和峰谷差,平稳负荷,提高电网的设备利用率。
With the popularity of electric vehicles,a large number of charging stations connected to the grid,it will bring large impact for the power, voltage and current of grid. This paper based on several scenarios of charging modes, such as plug and charge, night charging and intelligent charging, the corresponding EV load models have been established. Finally, an analysis is performed for the load characteristics of regional power grid to demonstrate the impacts of different EV charging scenarios. The result showed that using EV load characteristic can reduce maximum load of power grid,stabilize the load and improve equipment utilization.
