Power grid demand side management method and device

The invention discloses a power grid demand side management method and device. The method comprises the following steps: formulating each load control sequence based on a public transformer district of a power grid region; calculating a limit load control curve of the power grid region; obtaining a predicted load curve of the power grid region based on the collected load point data of the load control sequence; calculating a response curve of a response load of the power grid region according to a preset power capacity margin of the power grid region, the predicted load curve and the limit load control curve; and based on a segmented maximum response load strategy and a historical execution scheme of the power grid region, dividing the load control sequence, so that the corresponding load control sequence executes a power supply action associated with the response curve. According to the power grid demand side management method and device provided by the embodiment of the invention, ordered control of control
