The invention discloses an energy management algorithm applied to a 10kV charging station. The energy management algorithm comprises the steps of predicting photovoltaic output, other loads of a charging station system and EV load data of a complete scheduling period in the future based on a random forest algorithm and historical data; operating an ESS day-ahead scheduling algorithm, and obtaining an optimal SOC time-sharing distribution strategy of the ESS in the next complete scheduling period; operating the ESS real-time scheduling algorithm at the ESS real-time scheduling operation time point, and configuring the optimal charging and discharging strategy of the residual scheduling time slot for the ESS; carrying out information interaction through handshake operation of the charging pile and the EV, and recording SOC and inbound time information of the vehicle; and optimizing the CP charging power of all scheduling time slots in the time period from the initial state to the full charging state of the EV. According to the invention, a reasonable energy storage power station scheduling strategy and an EV ordered charging strategy are formulated, and limited charging stations are utilized to meet the energy charging requirements of large-scale electric vehicles. Meanwhile, the effects of suppressing the load fluctuation rate and reducing the load peak-valley difference are achieved for the charging station system, and the negative influence on the power system is reduced.

    本发明公开了一种应用于10kV充电站的能量管理算法,包括:基于随机森林算法与历史数据预测未来1个完整调度周期的光伏出力、充电站系统其他负荷与EV负荷数据;运行ESS日前调度算法,获取最优的未来1个完整调度周期ESS的SOC分时分布策略;在ESS实时调度运行时间点运行ESS实时调度算法,为ESS配置剩余调度时隙的最优充放电策略;通过充电桩与EV握手操作进行信息交互,记录车辆SOC、入站时间信息;优化该EV从初始至满充状态时间段内所有调度时隙CP充电功率。本发明制定合理的储能电站调度策略与EV有序充电策略,利用有限的充电站满足大规模电动汽车的充能需求。同时对充电站系统起到了抑制负荷波动率、降低负荷峰谷差的效果,降低了对电力系统的负面影响。
