The invention relates to the technical field of power systems, and provides a power grid spare capacity-based charging pile power supply method, which comprises the following steps of: calculating the safety capacity of a power grid; setting charging upper limit power for the charging piles connected to the power grid based on the centralized control system; querying the sum of the output powers of all the charging piles to obtain a total charging power, and calculating a total output power according to the total charging power; judging whether the total output power reaches the safety capacity of the power grid; if not, normally supplying power to a plurality of charging piles in the centralized control system, and ensuring that the charging power of the charging piles is smaller than the charging upper limit power; and if so, reducing the charging power of the plurality of charging piles in the centralized control system until the reduced total output power is less than the safety capacity of the power grid. The invention further provides a charging pile power supply device and equipment based on the idle capacity of the power grid and a storage medium. The charging pile is powered on based on the idle capacity of the power grid, the power grid is not impacted, and the application range of the charging pile can be widened.

    本发明涉及电力系统技术领域,提供了一种基于电网闲余容量的充电桩供电方法,包括:计算电网安全容量;基于集控系统为接入电网的充电桩设置充电上限功率;查询所有充电桩的输出功率之和,得到总和充电功率,并根据总和充电功率计算总和输出功率;判断总和输出功率是否达到电网安全容量;若未达到,则对集控系统中的多个充电桩正常供电,并确保充电桩的充电功率小于充电上限功率;若达到,则降低集控系统中多个充电桩的充电功率,直至降低后的总和输出功率小于电网安全容量。本发明还提出一种基于电网闲余容量的充电桩供电装置、设备及存储介质。本发明实施例基于电网闲余容量为充电桩供电,不冲击电网,可以提升充电桩的应用范围。
