Virtual power plant distributed scheduling method and system for assisting climbing

Abstract

The invention provides a climbing-assisted virtual power plant distributed scheduling method and system, and belongs to the technical field of power system operation and scheduling, and the method comprises the steps: obtaining power load information and power distribution network topological parameters, and constructing a hot start linearization power flow model; obtaining distributed resource operation parameters, and constructing a distributed resource physical operation model; based on the hot start linearization power flow model and the distributed resource physical operation model, a virtual power plant optimization scheduling model is constructed by taking the target optimization target as a constraint; decomposing the virtual power plant optimization scheduling model to obtain a power distribution network operation sub-problem and a plurality of virtual power plant operation sub-problems; and solving the operation sub-problems of the power distribution network to obtain an optimal scheduling strategy of the power distribution network, and solving the operation sub-problems of the plurality of virtual power plants to obtain an optimal scheduling strategy of the virtual power plants. The method provided by the invention is applied to the electric power system, and the climbing pressure of the main network electric power system is reduced.
