由于电动汽车快充过程中产生的功率波动会对配电网运行造成生较大冲击,需要从充电站层面考虑相应的补偿性措施.利用储能系统(ESS)的快速调节特性,本文提出了一种考虑充电负荷特性和风电出力波动的快充站ESS配置方法.ESS的配置不仅可以减轻快充站对配电网的功率波动影响,而且可以提高其经济效益.首先,采用场景法对配电网中的风电进行建模,并根据电动汽车特性和行驶概率,计算出各充电站的充电负荷需求.然后,综合考虑投资成本?维护成本?储能放电收益?弃风成本等因素,以电动汽车快充站ESS全寿命周期总成本最优为目标,建立了优化配置模型.最后,通过数学规划和优化建模软件GAMS对模型进行线性化处理并求解.通过改进的IEEE-69节点系统进行仿真,验证了该模型的可行性和经济性.“,”Fast charging stations play an important role in the use of electric vehicles (EV) and significantly affect the distribution network owing to the fluctuation of their power. For exploiting the rapid adjustment feature of the energy-storage system (ESS), a configuration method of the ESS for EV fast charging stations is proposed in this paper, which considers the fluctuation of the wind power as well as the characteristics of the charging load. The configuration of the ESS can not only mitigate the effects of fast charging stations on the connected distribution network but also improve its economic efficiency. First, the scenario method is adopted to model the wind power in the distribution network, and according to the characteristics of the EV and the driving probability, the charging demand of each station is calculated. Then, considering factors such as the investment cost, maintenance cost, discharging benefit, and wind curtailment cost, the ESS configuration model of the distribution network is set up, which takes the optimal total costs of the ESS for EV fast charging stations within its lifecycle as an objective. Finally, General Algebraic Modelling System (GAMS) is used to linearize and solve the proposed model. A simulation on an improved IEEE-69 bus system verifies the feasibility and economic efficiency of the proposed model.
