摘要:

为避免大量电动汽车(EV)无序充电对电网安全、经济运行的影响,提出了基于电动汽车入网(V2G)辅助服务的配电网日前调度方法。首先,基于智能电网和物联网的历史及实时信息建立EV充放电模型,并进行EV辅助服务参与者的筛选和分类。其次,建立了考虑V2G辅助服务的 2层配电网最优经济调度模型。上层模型以网损成本、EV用户成本和系统总负荷均方差最小为目标,优化充电站的充放电功率和电压调节设备的工作状态;下层模型以EV的充放电状态转换次数最少和充电站功率与上层优化结果偏差最小为目标,计算每辆参与辅助服务EV的充放电功率。最后,算例系统仿真验证了所提方法的有效性。

Abstract:

In order to avoid the impact of disordered charging of numerous electric vehicles (EVs) on secure and economic operation of power system, a day-ahead scheduling strategy of distribution network considering vehicle-to-grid (V2G) auxiliary service is proposed. Firstly, based on the history and real-time information of the smart grid and Internet of Things, the charging and discharging model of EVs is established, and the selection and classification of EV auxiliary service participants are carried out. Secondly, a bi-level optimal economic scheduling model of distribution network considering V2G auxiliary services is built. The upper level aims at minimizing grid loss cost, EV power cost and system load variance, and optimizes the charging and discharging power of the charging stations and the operating state of the voltage regulating equipment. The lower one is devoted to minimizing the switch time of EV charging and discharging state and the deviation between the charging station power and the upper optimization result, and figures out the charging and discharging power of each EV participant. Finally, the results of the example system verify the effectiveness of the proposed method.
