英国EV-elocity项目对我国V2G项目开展的借鉴与启示

Learning and inspiration of the UK EV-elocity project for V2G research in China

近年来我国在电动汽车领域发展迅速,但当大量电动汽车接入电网时会对电网的稳定性和可靠性构成挑战,而V2G技术可以平衡电网峰谷差和促进新能源消纳,提高电网的灵活性,从而有效缓解大量电动汽车无序接入电网带来的问题。以英国的EV-elocity项目为案例,深入分析了V2G项目的环境价值、电池老化和用户反馈等方面,这些也是目前我国在开展V2G项目中关注相对较少的问题。此外,还简要介绍了我国V2G项目的实施情况,并指出我国V2G研究在项目开展和研究方向层面所面临的问题。最后,针对环境价值、电池老化、用户体验和接受度等方面提出了相关建议,这些建议旨在缩小与发达国家在该技术领域的差距,从而推动我国V2G项目的开展和V2G技术的应用。

In recent years,China has been developing rapidly in the field of electric vehicles,but when a large number of electric vehicles are connected to the power grid,it will pose a challenge to the stability and reliability of the power grid.V2G technology can balance the peak-to-valley difference of the grid and promote the consumption of new energy,improve the flexibility of the grid,and thus effectively al-leviate the problems caused by the uncontrolled access of a large number of electric vehicles to the grid.Taking the EV-elocity project in the UK as a case study,the environmental value,battery aging and user feedback of the V2G project are analyzed in depth,which are also issues that have received relatively little attention in carrying out the V2G project in China at present.In addition,the implementation of V2G projects in China is also briefly introduced,and the problems faced by V2G research in China at the level of project development and research direction are pointed out.Finally,relevant suggestions are made with respect to environmental value,battery aging,user experi-ence and acceptance,which are aimed at narrowing the gap with developed countries in the field of this technology so as to promote the de-velopment of V2G projects and the application of V2G technology in China.
