摘要
为提高电动汽车充电站的经济性,需要结合储能系统对充电站容量进行合理配置。通过调研电动汽车的实际充电数据分析充电站的负荷特性,得知不同规模的充电站应配置不同容量的储能系统。利用惩罚因子,以充电站年净收益为优化目标,在未配置储能和配置储能的情况下分别建立了充电站容量配置模型,并利用数学方法对其进行求解。在某充电站进行了算例仿真,验证了所提配置模型的有效性。
In order to improve the economics of electric vehicle charging stations,it is necessary to reasonably configure the charging station capacity in conjunction with the energy storage system.By investigating the actual charging data of electric vehicles and analyzing the load characteristics of charging stations,it is known that different sizes of charging stations should be equipped with different capacities of energy storage systems.Utilizing the penalty factor and taking the annual net income of the charging station as the optimization target,the capacity allocation model of the charging station is established separately with and without the energy storage configuration,and the mathematical method is used to solve it.Finally,a simulation example is carried out at a charging station to verify the effectiveness of the proposed configuration model.
