纯电动快递配送车V2G削峰填谷经济效益分析

Economic Analysis of Electric Express-delivery Vehicles Providing V2G Service for Peak Shaving and Valley Filling

纯电动快递配送车可作为储能单元提供电动汽车与电网互动(Vehicle-to-Grid,V2G)削峰填谷增值服务。以实际V2G充电站为例,在分析影响V2G经济运行因素的基础上,建立充放电投资效益分析模型。考虑分时电价和循环寿命,测算电动汽车不同电池类型参与V2G的成本和利润,并对比不同电池价格下和不同峰谷运行模式下的收益率。结果表明,通过响应分时电价,纯电动快递配送车具有明显的V2G经济效益,不同电池容量配比影响V2G收益率,电池容量并非配置越多收益越大。所得结果可为纯电动快递配送车V2G经济效益测算提供一定依据。

Electric express-delivery vehicles can be used as energy storage unit to provide V2G service,participating in peak shaving and valley filling for power system.Taking an actual V2G charging station as an example,an investment benefit analysis model of charging and discharging for electric vehicle was established based on the analysis of the factors affecting the economic operation of V2G.Considering time-of-use price and cycle life,the cost and profit of different battery types participating in V2G of electric vehicle were calculated,and the rate of return under different battery prices and different peak valley operation modes was compared.The analysis shows that the electric express-delivery vehicle has obvious economic benefits of V2G by responding to time-of-use price.Different battery capacity ratio affects V2G yield,and it is not that the more battery capacity,the greater the profit.The result provides a certain basis for economic benefit calculation of electric express-delivery vehicle providing V2G service.
