The invention relates to the technical field of electric vehicle two-way charging piles, in particular to a multi-vehicle-pile emergency power supply small-granularity power dispatching and electric vehicle order dispatching method. The method comprises the following steps: multiplexing a bidirectional charging pile as a transformer area emergency power supply; when the power grid is powered off, a multi-vehicle and multi-pile networking control strategy is adopted to construct a micro-grid to supply power to a transformer area load; when the electric vehicle supply outside the station is limited, power distribution among the multiple vehicle pile units is optimized and dispatched according to the arrival time of the electric vehicle outside the station and the real-time power output capacity of each vehicle pile unit in the station; and when the supply of the electric vehicles outside the station is excessive, the arrival time of the electric vehicles is dispatched according to the power supply duration time of each vehicle pile unit. According to the invention, under a brand new scene that the bidirectional charging pile is reused as an emergency power supply, it is ensured that the multi-pile unit has continuous and stable emergency power supply capability for the transformer area, and meanwhile, waiting and congestion caused by inconsistency between the arrival time of the electric vehicle outside the station and the time of exhaustion of the electric vehicle in the station are also avoided.

    本发明涉及电动汽车双向充电桩技术领域,尤其是涉及多车桩应急供电小颗粒度功率调度及其电动汽车派单方法。所述方法包括如下步骤:将双向充电桩复用为台区应急电源;电网停电时,采用多车多桩构网控制策略来构建微电网为台区负荷供电;在站外电动汽车供应有限时,根据站外电动汽车到站时间和站内各车桩单元的实时功率输出能力来优化调度多个车桩单元间的功率分配;当站外电动汽车供应过剩时,按照各车桩单元的供电持续时间来调度电动汽车的到站时间。本发明能在将双向充电桩复用为应急电源的全新场景下,保证多车桩单元对台区具有连续且稳定的应急供电能力,同时也避免了站外电动汽车到站时间与站内电动汽车耗尽电量时间不一致而造成等待和拥堵。
