The invention relates to the technical field of electric pile power grid distribution systems, and discloses an optimization system based on large-scale access of electric piles to an existing power distribution network, the optimization system comprises a power distribution time division multiplexing system, the power distribution time division multiplexing system comprises a community module, and the output end of the community module is electrically connected with a transformer module, the output end of the transformer module is electrically connected with a power distribution room low-voltage switch, the power distribution room low-voltage switch is electrically connected with a power distribution box module, and the output end of the power distribution box module is electrically connected with total current parameters of a phase A, a phase B and a phase C. By arranging the power distribution time division multiplexing system, when there are especially many charging devices, power distribution capacity time division can be achieved on the basis of current capacity overmatching, topology of a power distribution network corresponds to an information node, data acquisition is realized through the Internet of Things, hierarchical optimization decision is realized through edge computing and cloud computing, the charging piles are prevented from influencing power utilization balance, and capacity overmatching without overload is realized on the premise of ensuring safety.

    本发明涉及电桩电网分配系统的技术领域,且公开了基于电桩大规模接入现有配电网的优化系统,包括配电分时复用系统,配电分时复用系统包括有小区模块,小区模块的输出端电连接有变压器模块,变压器模块的输出端电连接有配电房低压开关,配电房低压开关电连接有配电箱模块、配电箱模块的输出端电连接有A相、B相和C相的总流参数,通过设置配电分时复用系统,当充电设备特别多时,配电容量分时可以在当前容量超配的基础上,将配电网络的拓扑对应到信息节点,通过物联网实现数据采集,通过边缘计算和云计算实现分级优化决策,避免充电桩影响电力的用电平衡,并在确保安全的前提下,实现容量超配而负荷不过载。
