中文摘要:

      对电动汽车的充放电进行合理控制能够提高电力系统调度的安全性和经济性，也可以大幅降低电动汽车用户的充电成本。需求响应策略是电动汽车有序充放电的关键技术之一，可以解决大规模电动汽车入网所带来的一系列问题，且能提高可再生能源在电网中的消纳比例，是国内外学者广泛研究的课题。首先，阐述了需求响应的相关背景和相应技术；然后，针对需求响应的特性，分别对基于价格和激励需求响应的电动汽车充放电策略进行了分析，并对用于电动汽车充放电的需求响应策略进行了对比；最后，对我国发展用于电动汽车充放电的需求响应提出相关建议。

英文摘要:

      Reasonable control of charging and discharging for electric vehicles（EVs）can improve the safety and economy of electric power system, and significantly reduce charging costs for EV users. The demand response strategy is one of the key technologies for orderly charging and discharging of EVs, which can solve a serious of problems caused by large-scale EVs interfacing with the grid and improve the consumption ratio of renewable energy in the grid. It has been widely studied by scholars at home and abroad.Firstly, the background and technology of demand response are illustrated. Then, aiming at the characteristics of demand response,the price-based and incentive-based demand response strategies are analyzed and compared respectively. Finally, relative suggestions are put forward for the domestic development of demand response for charging and discharging of EVs.
