With the reform of the energy structure, the types of loads on the energy demand side are becoming more and more diverse.In order to effectively coordinate the source-load-storage supply and demand relationship in the microgrid and improve the multi-energy coupling and multi-energy complementary scheduling capabilities in the microgrid, this paper proposes A joint optimal scheduling method based on energy routers to manage source-load-storage in microgrids.First, establish an energy router source-load-storage energy conversion expansion model considering flexible load participation in scheduling.On this basis, with the minimum daily operating cost as the optimization goal, an optimal scheduling considering the supply-demand relationship of source-load-storage is established.model;secondly, an improved whale optimization algorithm solution strategy based on nonlinear weight factor is proposed, and a typical daily microgrid source-load-storage joint scheduling scheme is obtained;finally, the source-load-storage proposed in this paper is verified by an example.Joint dispatch can improve the consumption capacity of new energy and effectively reduce the daily operating cost.
