Problems solved by technology

[0005] (1) Some existing technologies can only solve linear optimization problems, but the actual scheduling problem is very complicated, and nonlinear factors need to be considered. Traditional optimization algorithms such as Benders decomposition cannot solve this problem, and some such as particle swarm optimization algorithm can obtain The results can easily converge to a local optimal solution
[0006] (2) The existing technology can only obtain the dispatch instruction at that time after obtaining the information of a dispatch time, and there is no effective solution to the randomness of the new energy unit output and load expectation in the real-time dispatch stage

Abstract

The invention provides a micro-grid group cooperative scheduling method and device, electronic equipment and a storage medium, and belongs to the technical field of micro-grid group cooperative scheduling control. Each micro-grid in the micro-grid group comprises a diesel generating set, a wind generating set, an energy storage device and an electrical load, and an electric vehicle cluster is used as mobile energy storage between the micro-grids. The method comprises the following steps: constructing a micro-grid group collaborative scheduling model; converting the micro-grid group collaborative scheduling model into a corresponding Markov decision process model; optimizing the Markov decision process model by using an SAC algorithm to obtain an optimal strategy model; and outputting a real-time scheduling instruction of the micro-grid group according to the optimal strategy model. According to the invention, collaborative scheduling of the micro-grid group containing the electric vehicle cluster can be realized, and the method has the characteristics of wide compatibility and high adaptability.

Description

technical field [0001] The disclosure belongs to the technical field of micro-grid group coordinated scheduling control, and in particular relates to a micro-grid group coordinated scheduling method, device, electronic equipment and storage medium. Background technique [0002] In the face of large-scale distributed new energy access, the microgrid needs to coordinate the output of various power sources to solve the ensuing problems of power quality, power system operation and control, new energy consumption, and power suppliers. communication among consumers, etc. Microgrid groups can provide corresponding solutions for large-scale power supply, but the power generation and power load of each microgrid are unbalanced. Nowadays, with the development of electric vehicles, the use of electric vehicle clusters as mobile energy storage provides a suitable solution for the coordinated interconnection and energy mutual aid between microgrid groups, which can transfer surplus elec...
