摘要
针对电动汽车充电站负荷利用率低,给配电网和变压器造成巨大压力等问题,研究了储能系统的优化配置。从电动汽车无序充电和有序充电两个方面分析了充电站的负荷特性,对充电站的储能容量配置进行了简单的分析探讨,包括储能电池、容量配置以及功率配置并总结了储能配置的优化运行问题。分析可知,在电动汽车充电站合理配置储能系统可以较好地平抑负荷波动,缓解对电网的冲击。
Aiming at the problems of low load use ratio of electric vehicle charging station,causing huge pressure on the distribution network and transformers,this paper researched on the optimal configuration of energy storage system.The load characteristics of the charging station were analyzed from the aspects of disordered charging and orderly charging of electric vehicles.This paper briefly analyzed the storage capacity configuration of the charging station,including energy storage battery,capacity configuration and power configuration,and summarized the problem of optimal operation of the energy storage configuration.The analysis shows that the rational allocation of the energy storage system in the electric vehicle charging station can better suppress the load fluctuation and mitigate the impact on the power grid.
