在笔者看来，《通知》的发布标志着车网互动从前期的探索研究、局部示范阶段，迈入推进规模化应用 试点落地的新阶段。 车网互动，简言之就是新能源汽车借助充换电设施与供电网络互联互通，实现两者间能量双向流动及信 息交互，其主要形式涵盖智能有序充电、双向充放电（V2G）等。在构建起新能源汽车与供电网络的信 息流、能量流双向互动体系后，车网互动能够充分挖掘车载动力电池的潜力，使其发挥出可控负荷或移 动储能的灵活调节能力。当电网负荷高峰时，新能源汽车可向电网放电，补充电力供应；在负荷低谷 时，车辆则从电网充电，储存电能。 事实上，一些企业早已敏锐捕捉到车网互动领域蕴藏的巨大潜力，并积极投身实践。南方电网先行先 试，于3月28日组织开展国内首次车网互动跨省联动，活动范围覆盖63个城市，超10万辆次新能源汽车 踊跃参与，促进消纳新能源电量50万度，车主也借此获得收益超40万元。特来电牵头或参与超过8个试 点项目，目前正在V2G充放电设施、光储充放一体化充电站、微电网、虚拟电厂等方面加大布局力度。 蔚来汽车与北京电力携手合作，开展"北京市基于新型储能的V2G车网互动协同调控试点项目"的研究， 已在北京通州宋庄地区投运一套蔚来第3 ...
