摘　　要：随着电动汽车的普及,车辆到电网(vehicle to grid,V2G)技术成为实现能源高效利用和电网稳定运行的关键。该文探讨了V2G技术在电网负荷管理中的应用,包括削峰填谷和提供调频/调压服务。通过分析锂电池的最大放电能力,V2G系统能够在电网负荷高峰时提供辅助调度功能,而在负荷低谷时,通过双向电能交换机制,电动汽车可以在电价低时充电,在电价高时放电,从而实现经济效益。该文进一步将V2G车网模型与市场电价耦合,对电动汽车在参与电网服务中的潜在收益和成本进行了详细分析,为V2G技术的商业化和电网的可持续发展提供了理论支持。With the popularity of electric vehicles,vehicle to grid(V2G)technology has become the key to achieving efficient use of energy and stable operation of the grid.This paper discusses the application of V2G technology in power grid load management,including peak cutting and valley filling and providing frequency/voltage regulation services.By analyzing the maximum discharge capacity of the lithium battery,the V2G system can provide auxiliary scheduling function during the peak load of the grid,and at the low load,through the two-way power exchange mechanism,the electric vehicle can be charged when the price is low and discharged when the price is high,thus achieving economic benefits.This paper further coupled the V2G vehicle network model with the market price,and carried out a detailed analysis of the potential benefits and costs of electric vehicles participating in grid services,which provided theoretical support for the commercialization of V2G technology and the sustainable development of power grids.
