Energy scheduling system and method for multiple integrated energy communities based on source-load matching degree

Abstract

The invention discloses a multi-integrated energy community energy scheduling system and method based on a source-load matching degree. The system comprises a management center and a plurality of integrated energy communities, and electric energy interaction and information interaction are carried out between the integrated energy communities, and between the integrated energy communities and the management center. The management center enables the comprehensive energy communities to carry out power interaction system supply and demand balance according to a source-load matching strategy; when the electric energy interaction among the integrated energy communities still cannot meet the load demand, the management center purchases electricity from the power grid; the management center establishes a matching index to realize quick docking between vacant communities and surplus communities in the same time period, so that communities with high transmission loss ratio due to less interaction energy are eliminated, and information circulation is reduced; with the purpose of minimizing the scheduling cost of a single integrated energy community and the interaction cost of multiple integrated energy communities, the solved optimal scheduling result can effectively reduce the total operation cost of the integrated energy communities, and benefit balance among the subjects is considered while the subjects pursue the maximum benefit.

Description

technical field [0001] The invention relates to the technical field of market energy distribution, in particular to a multi-comprehensive energy community energy scheduling system and method based on source-load matching degree. Background technique [0002] Energy Internet construction is an important measure to seek a resource-saving and environmentally friendly sustainable development path. It makes possible the parallel development of cold and hot electricity in the region, and the collaborative optimization between production and supply. The park-level integrated energy service provider is one of its typical applications. . At present, due to the advantages of flexibility, efficiency, cleanliness and environmental protection, and multiple interactions, the penetration rate of distributed energy in modern energy systems continues to rise. The production and consumption methods of user-side electric energy in traditional parks have also been changed, using user terminal ...

AI Technical Summary

Problems solved by technology

[0005] Most of the existing research optimizes the resources in the community from the perspective of a single comprehensive energy service provider, which lacks the consideration of the energy sharing model among the subjects of the comprehensive energy service provider, and does not consider the sources of different subjects in the pursuit of multi-subject energy interaction. The problem of load matching degree is not conducive to the optimal allocation of resources in the integrated energy system
