Abstract

As the larger error between the dispatch plan of the previous day and the actual operation of the community multi-type energy coupling system, the actual operation cannot be fully meet. A two-stage optimization dispatch method of the community multi-type energy coupling system based on the particle swarm algorithm is proposed in this study. Firstly, the optimal dispatch model of community multi-type energy coupling system on previous day is established. Minimizing the daily operation cost is the objective function. The optimal dispatch curve of community multi-type energy coupling system on previous day is obtained. Secondly, based on the optimal dispatch curve of community multi-type energy coupling system on previous day, an intraday correction model is constructed. The example results show that the proposed model can eliminate the dispatch error of the previous day and realize the optimal operation of community multi-type energy coupling system.
