The present disclosure provides a power control method for a charging station and a power control apparatus and system of a charging station, and belongs to the field of charging station control. The power control method includes: acquiring a power supply capability parameter broadcasted by the energy storage system, a power supply capability parameter broadcasted by the power grid system, and a current power demand broadcasted by each target charging device; calculating a first maximum available power of the charging station based on the power supply capability parameter of the energy storage system and the power supply capability parameter of the power grid system; determining a first power limit of each target charging device based on the first maximum available power of the charging station, the current power demand broadcasted by each target charging device, and a predetermined allocation rule; and broadcasting the first maximum available power of the charging station and the first power limit of each target charging device to each target charging device, so that each target charging device performs power output based on the first power limit, determines whether a sudden drop in a power supply capability occurs, and reduces a power limit of the target charging device to a second power limit when the sudden drop in the power supply capability occurs. In the present disclosure, power grid overload can be effectively avoided.
