摘　　要：针对城市高峰电力负荷大、持续时间短的特点,采用车网互联(V2G)模式,通过电动车集群晚间低谷充电,白天停驶时反馈给电网以支持高峰电力负荷,有利于城市电网削峰填谷,并提高能源利用效率。以带有30 kW.h动力电池的电动车集群集中放电来支持上海地区12 h的800 MW高峰电力为例,通过V2G模式中成本和收益的经济核算,发现电动车主和电网企业都能从V2G模式中受益。与风能、太阳能一样,V2G模式是一种节能、环保、可持续发展的模式。Vehicle-to-grid（V2G） mode is adopted in urban power grid for load shifting due to grid features such as big peak load and short time duration.The electric vehicles charge during night and send power back to grid during peak time in the day.The method can effectively flatten the load curve and improve energy utilization efficiency.Analysis was performed on an electric vehicle fleet with 30 kW·h battery per vehicle in Shanghai district grid which has 12 hours of 800 MW peak load annually.The economic evaluation of costs and profits indicates that both vehicle owners and utilities can benefit from V2G mode.Same as wind power and solar power,V2G is an energy saving,environment friendly and sustainable development energy mode.
