全球车网互动标准进展研究及相关建议

Research on the Progress of Global Vehicle to Grid Standards and Relevant Suggestions

在电网“双高”、“双峰”特征及“双碳”目标下,电动汽车与电网互动技术(vehicle to grid,V2G)的落地应用可为电网提供多元化辅助服务、平抑新能源波动,促进能源清洁低碳转型。随着车网互动试点规模不断扩大,相关终端设备与系统平台升级改造任务量大、成本高,亟需研究并完善我国V2G标准体系,对车、桩、网三者间信息与能量互动接口进行标准化设计与规范。首先,文章分析国外相关标准化机构及V2G标准制修订情况,梳理了IEC相关技术委员会、工作组及标准对应情况;其次,按照车、桩、网3个方面分析国内V2G标准化现状;最后,对比分析国内外标准间的优缺点,结合产业与技术发展趋势,提出我国V2G标准体系设计建议。

Under the "double high" and "double peak" characteristics of the power grid and the "dual carbon" goal,the application of V2G technology(Vehicle to Grid) can provide the power grid with diversified auxiliary services and smooth the fluctuation of new energy, promote energy clean and low-carbon transition. With the continuous expansion of the V2G pilot scale, the upgrading and transformation of related terminal equipment and system platforms has a large number of tasks and high costs. It is urgent to study and improve V2G standard system, and to standardize the design of the information and energy interaction interface between the vehicle, charging pile and grid. Firstly, the development and revision of relevant foreign standardization organizations and V2G standards are analyzed, and the IEC technical committees, working groups, and standards correspondence are summarized. Secondly, the current status of domestic V2G standardization in terms of vehicles, charging piles, and grid are analyzed. Finally, the advantages and disadvantages between domestic and foreign standards are analyzed, combined with the development trend of industry and technology, Chinese V2G standard system design recommendations are presented.
