考虑电动汽车充放电模式灵活性的配电网日前优化调度方法
摘要:在聚合商管理模式下，对大规模插电式电动汽车(electric vehicles, EV)调节容量的高效利用可降低系统运行成本，助力可再生能源(renewable energy resources, RES)消纳。同时，随着EV快速充电设施的普及，相较于慢充而言，快充模式下EV参与电网辅助服务时可能存在更多灵活性，但无疑也考验着电力系统承受能力。为充分利用需求侧灵活性资源，考虑将快速充电概念应用于电动汽车入网(vehicle to grid, V2G)场景中，即考虑双向的快速功率，提出考虑EV充放电模式灵活性的配电网日前经济调度方法，其包含2个模型：考虑充放电模式的EV聚合模型与配电网经济调度模型。通过算例分析验证了该策略可提升EV可调度区域灵活性，并能为配电网经济调度带来可观效益。
Abstract：Under the aggregator management model, efficient utilization of the regulation capacity of large-scale electric vehicles (EV) can reduce system operating costs and facilitate the consumption of renewable energy resources (RES). At the same time, with the popularization of EV fast charging facilities, compared with slow charging, there may be more flexibility for EV to participate in grid auxiliary services under fast charging mode, but it is undoubted that the affordability of the power system is tested. To give full play to the advantages of resource flexibility on the demand side, this paper considers applying the fast charging concept to vehicle to grid (V2G) scenario i. e. considering the two-way fast power, and a day-ahead economic scheduling method for distribution networks considering the flexibility of EV charging and discharging modes is proposed. It includes two models: the EV aggregation model considering charging and discharging modes and the distribution network economic dispatch model. The results show that the strategy improves the flexibility of the dispatchable domain of EV and brings considerable benefits to the economic scheduling of the distribution network.
