Distributed Dispatching Method for Intelligent Distribution Network Based on the Multi-node Integration of Energy Microgrid

The demand for power exchange between comprehensive energy microgrids and distribution networks is rapidly increasing with the installation capacity of distributed energy sources within the microgrid. If these two systems remain interconnected only by a single link, it may restrict the spatiotemporal flexibility of comprehensive energy microgrids due to capacity constraints, thereby limiting the integration of clean energy. This paper presents an intelligent distribution network distributed optimization and scheduling method for a multi-comprehensive energy microgrid, where each comprehensive energy microgrid can be interconnected through multiple nodes. This method takes into account various flexible resources on the generation, network, load, and storage sides and their impacts on the scheduling scheme. Case studies on an improved IEEE 33-node system are conducted based on the method proposed in this paper. The results reveal that for comprehensive energy microgrids with high-capacity distributed energy sources, a multi-node interconnection mode can enhance system flexibility and significantly improve the operational efficiency of all participating entities.
