电动汽车发展现状及充电技术研究

摘要

The development of electric vehicles has become world trend, this will cause a great impact on power system operation.Electric vehicle charging control will be an ad-hoc way of operation control system.It not only can reduce the load of the charging hazard, but also can achieve peak load shifting load function, promote new energy consumptive and improve the effectiveness of load dispatch.This paper provides some of research situation in the field of charge control and electricity load.It mainly comprises a model simulation and analysis of charging load, charging control strategy study, prospect of charge control benefits.Moreover, it pointed out the outstanding issues and research directions.%发展电动汽车已经成为当今世界的热潮,这对电力系统的运行将会造成极大的影响.电动汽车充电控制将变成系统运行控制的特定方式,一方面可以减轻充电负荷造成的危害,另一方面也可以实现负荷削峰填谷的功能,促进新能源消纳的作用,提高负荷调度的功效.文章概述了近年来充电控制、充电负荷领域内的一些研究状况,主要包括充电负荷模型的仿真分析、充电控制策略的研究、充电控制效益的展望等方面;另外也指出了尚未解决的问题和可能的研究方向.
