摘要
规模化电动汽车与电网双向有序互动可为电网提供多元化辅助服务、平抑新能源出力和负荷波动,同时电动汽车用户可节省充电成本,并通过向电网提供辅助服务获得收益。介绍了电动汽车与电网双向智能互动的基本概念和发展情况,阐释了电动汽车与电网互动(简称为“车网互动”)的典型应用场景、能量优化管理策略和通信协议标准现状,并针对典型示范项目分析了国内外车网互动的技术思路和主要结论及成效,对比总结了国内外示范项目的特点、经验和局限性。结合我国相关产业与技术发展趋势,针对目前国内试点项目的局限性,从理论研究、商业模式、市场机制等方面给出了我国车网互动技术未来发展的建议。
The bi-directional ordered integration between large-scale EVs(Electric Vehicles) and power grid can provide diversified auxiliary services for the power grid,smooth the fluctuation of new energy output and load,meanwhile,EV users can save charging costs and obtain profits by providing auxiliary services to the power grid. The basic concept and development situation of bi-directional intelligent integration between EVs and power grid are introduced. The typical application scenarios,energy optimization management strategy and communication protocol standard for VGI(Vehicle Grid Integration) are explained. In view of the typical demonstration projects,the technical ideas,main conclusions and achievements of domestic and foreign VGI are analyzed,and the characteristics,experience and limitations of the domestic and foreign demonstration projects are compared and summarized. Combining with the trends of related industry and technology,and aiming at the limitations of domestic VGI pilot projects,some suggestions on the future development of China VGI technology from the perspectives of theoretical research,business modes,market mechanism,and so on,are given.
