The invention discloses a scheduling control method and system for a mobile plug-and-play energy storage power station; the method comprises the steps of monitoring the power grid load change rate ofa power grid in the current preset time period; monitoring the position information, the capacity information and the state of charge of all the movable plug-and-play energy storage power stations; determining a grid-connected position wherein the movable plug-and-play energy storage power station needs to be added in the next preset time period; determining a first rescue radius according to theposition of the low-voltage side of the transformer needing to be added with the movable plug-and-play energy storage power station and the load change rate of the power grid, and determining all movable plug-and-play energy storage power stations which can work in the first rescue radius; determining the electric quantity required to be absorbed or transmitted out by the power grid according to the load change rate of the power grid and the current change proportion coefficient; and selecting the movable plug-and-play energy storage power station meeting the demand electricity from all the movable plug-and-play energy storage power stations capable of working, and carrying out electric quantity balance.
