摘　　要：随着新能源大规模接入电力系统,激励电动汽车参与电网调节,挖掘充电负荷的填谷潜力,已成为提升新能源消纳空间的重要手段之一。首先,构建城市公共充电站填谷潜力评估框架,对充电订单进行概率建模,开展基于随机抽样的蒙特卡洛模拟,从而获得表征起始充电时刻的抽样数据结果。然后,提出包含谷期和平期负荷率在内的典型负荷特性指标,引入充电负荷填谷潜力评估参数,开展城市公共充电站的填谷潜力评估。最后,采用某省试点地市的城市公共充电站在不同价格激励下的真实充电订单数据,基于所提方法开展了试点地市所属省份城市公共充电站填谷潜力量化评估。结果表明,模拟的充电负荷和实际负荷走势一致、变化规律与实际情况相似,当该省服务费优惠超过七折后,服务费每降低1折,平均填谷响应约增加2.36万kW,实现了对价格激励的城市公共充电站填谷潜力评估。With large scale integration of renewable energy,motivating valley-filling users to participate in power grid regulation to tap the valley-filling potential of charging loads has become one of the important means to enhance the space for renewable energy consumption.Firstly,an evaluation framework for valley-filling potential of urban public charging stations is built in this paper.Probability modeling is conducted on charging orders,and a random sampling-based Monte Carlo simulation is carried out to obtain the sampling data representing the starting charging time.Then,the typical load characteristic indicators including valley-period and flat-period load rates are proposed,and the charging load valley-filling potential evaluation parameters are introduced to carry out valley-filling potential evaluation of urban public charging stations.Finally,based on the actual charging order data of the urban charging stations in a pilot city under different price incentives,a quantitative evaluation of the valley-filling potential of urban public charging stations is carried out.The results show that the simulated charging load is consistent with the actual load in tendency,and the change pattern is similar to the actual situation.When the service fee discount exceeds 30%,for every additional 10%discount,the average valley-filling response will increase by approximately 23.6 MW.Therefore,the proposed evaluation framework realizes the quantification of valley filling potential of public charging stations.
