| 摘 要： | 概述了电动汽车的功率特性,以蒙特卡洛模拟法仿真电动汽车的充放电行为,建立了电动汽车无序充电和有序充放电的负荷模型。在分时电价机制下,以计及电动汽车接入的微网经济效益最大为目标,制定了优化调度策略。分析比较了电动汽车无序充电和有序充放电对微网优化运行的影响,表明电动汽车有序充放电接入模式不仅对主网起到＂移峰填谷＂的作用,还可以有效提高微网自身的经济效益。

| Abstract: | This paper summarizes the power performance of electric vehicle, simulates its charging and discharging by applying Monte Carlo method and builds the load model of its uncoordinated charging as well as controlled charging and discharging. Based on mechanism of Time of Use（TOU）, the aim of microgrid maximum economic benefit concerned with the access of electric vehicle can be achieved by developing optimal scheduling strategy. In addition, the comparison of the effects on microgrid optimal operation corresponding to uncoordinated charging and controlled charging of electric vehicle indicates that the access mode of controlled charging and discharging not only helps Load Shifting of the main grid but also the economic benefit of the microgrid itself. |
