Abstract
The invention provides a multi-element flexible load scheduling method, device and equipment based on controllable margin, and relates to the technical field of power grid scheduling, and the method comprises the steps: calculating the power margin, time margin and energy margin of each flexible load in a target power grid; the flexible load comprises an air conditioning load, an electric vehicle load and an energy storage load; according to the power margin, the time margin and the energy margin of each flexible load, calculating the controllable margin of each flexible load, and screening out a plurality of adjustable flexible loads from all flexible loads of the target power grid; selecting at least one target node and a target flexible load in each target node from the plurality of nodes based on the corresponding relationship between the plurality of adjustable flexible loads and the nodes and the target adjustment power of the target power grid; and obtaining a load scheduling scheme of the target power grid according to the target adjustment power and the operation parameters of each target flexible load. According to the method, the flexible load can be quantified, stable operation of the target power grid is guaranteed, and regulation and control failure is avoided.
