摘要
随着电动汽车的发展,充电用户越来越多,同时也出现了一系列问题,尤其是无序充电带来的充电成本高、充电排队时间长和电网负荷安全影响等问题,制约着电动汽车和充电设施的发展。为解决此类问题,文章研究和设计有序充电策略。通过研究电动汽车充电过程数据,分析充电电压、电流、SOC和充电时间的关系曲线,在不同的电价时段和车多桩少情形下制定了合理的中止充电SOC值;为了提高充电站运营效益,针对充电站服务车辆对象的不同,设计了不同充电桩限功率有序充电策略。充电站有序充电策略的实现能够提高运行收益、减低成本,让用户充电时间更合理,提高了充电体验性,使充电站与电网互动,对电网削峰填谷,减小负荷波动率,提高了电网的安全性。
With the development of electric vehicles, there are more and more charging users. Meanwhile, there are a series of problems, especially the high charging cost, long charging queue time and power grid load safety impact brought by disordered charging, which restrict the development of electric vehicles and charging facilities. To solve such problems, this paper studies and designs orderly charging strategy. By studying the charging process data of electric vehicles, the relationship curves of charging voltage, current, SOC and charging time are analyzed, and the reasonable SOC value of stopping charging is formulated in different electricity price periods and the situation of more vehicles and less piles. In order to improve the operation income of charging stations, the power limiting and orderly charging strategies of different charging piles are designed according to the different vehicles served by charging stations. The implementation of charging station orderly charging strategy can improve the operation income, reduce the cost, make the charging time more reasonable, improve the charging experience, make the charging station interact with the power grid, conduct the peak-load shaving, reduce the load fluctuation rate, and improve the security of the power grid.
