摘要
目前,汽车到电网(Vehicle to Grid,V2G)技术正受到人们的广泛关注,这是因为通过V2G,电网效率低以及可再生能源波动的问题不仅可以得到很大程度的缓解,还可以为电动车用户创造收益。本文首先给出了V2G的概念及其可行性评估情况,其次根据应用对象的不同将V2G的实现方法分成四类,综述了V2G涉及的关键问题:智能调度、智能充放电管理、双向充电器以及V2G运行对电池的影响,并且介绍了国内的相关研究情况。最后对V2G涉及的各项先进技术及发展趋势进行总结,并结合我国具体国情提出了相关建议。
At present the V2G （vehicle to grid） technology is drawing people＇s attention, which can relieve the problems of low grid efficiency and renewable energy fluctuation, and also bring EV owners profits. In this paper the concept and evaluation of V2G are firstly described, then the implement method is classified according to different objects. The paper reviews the key problems which are referred to by V2G, such as intelligent dispatching and intelligent charging/discharging management, bi-directional charger as well as the effect of V2G on battery, and introduces the research in China. Finally the key technologies are concluded as well as the developing trends, and some advices are given according to the condition of China.
