The invention relates to the technical field of electric vehicle two-way charging piles, in particular to a small-granularity optimization scheduling method for a multi-vehicle-pile-unit area emergency power supply system, and the method comprises the following steps: multiplexing a two-way charging pile as an area emergency power supply; when the power grid is powered off, the vehicle pile unit adopts a multi-vehicle and multi-pile networking control strategy to construct a micro-grid to supply power to the transformer area load; a corresponding objective function is calculated according to the real-time energy storage capacity and the power output capacity of each vehicle pile unit, then the proportion of an optimal global power instruction is obtained by using a multi-objective particle swarm optimization method, and the damping coefficient of each vehicle pile unit is dynamically adjusted according to the proportion. Under the brand new scene that the bidirectional charging pile is reused as an emergency power supply, the emergency power supply load can be dynamically distributed to achieve the purpose that the concurrence time of each vehicle pile unit is consistent as much as possible, the purpose that a battery of a certain vehicle pile unit is prevented from being overheated and then network quitting is avoided can be achieved, the number of emergency power supply for multi-machine concurrence network construction is guaranteed, and the power supply efficiency is improved. And the load resistance and impact resistance of the system are improved.

    本发明涉及电动汽车双向充电桩技术领域,尤其是涉及多车桩单元台区应急供电系统的小颗粒度优化调度方法,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;电网停电时车桩单元采用多车多桩构网控制策略构建微电网为台区负荷供电;根据各车桩单元实时的储能量和功率输出能力来计算相应目标函数,进而使用多目标粒子群优化方法获取最佳全局功率指令的比例,并以此动态调节各车桩单元的阻尼系数。本发明在将双向充电桩复用为应急电源的全新场景下,既能动态分配应急供电负荷以实现各车桩单元的并发时间尽量一致的目标,又能实现避免某车桩单元的电池过热而退网的目标,保证多机并发构网应急供电的数量,提高系统的抗负荷抗击能力。
