V2G(Vehicle-to-Grid,电动汽车与电网互联)技术的应用可以实现电网与车主的双赢.从电网角度,可以发挥削峰填谷、平抑新能源功率波动、延缓电网升级改造等作用;从用户角度,在满足用车的要求下可获取附加效益.随着电动汽车的推广和新能源并网规模的发展,V2G技术得到更多的关注.然而,V2G技术的发展仍然面临规模化互动、运营、调度等技术及经济性问题.因此,从V2G技术发展的现状出发,重点阐述V2G技术在新能源并网中的作用和应用模式;并对V2G技术在新能源并网中的充放电策略、电池寿命预测以及综合价值进行了探讨.V2G技术在新能源并网中的推广应用不仅可以提升新能源并网利用率,还可进一步提升电动汽车的减排效果.
Application of Vehicle-to-Grid Technology in New Energy Grid Connection
The application of V2G(Vehicle-to-Grid)technology can achieve a win-win situation for both the grid and the vehicle owner.From the grid's perspective,it can achieve peak shaving and valley filling,smooth out new energy power fluctuations and delay grid upgrades;from the user's perspective,additional benefits are gained in meeting the requirements of the vehicle.With the promotion of electric vehicles and the development of the scale of new energy grid connection,V2G technology has received more attention.However,the development of V2G technology still faces technical and economic issues such as scale interaction,operation and scheduling.Therefore,from the current situation of V2G technology development,the role and application mode of V2G technology in new energy grid connection was focused on,and the charging and discharging strategy,battery life prediction and comprehensive value with V2G application in new energy grid were also discussed.It shows that V2G technology can not only improve the utilization rate of new energy grid connection,but also further improve the emission reduction effect of electric vehicles.
