Abstract: With the increasing interconnection of regional microgrid (MG), the full utilization of energy and stable operation of the system have become the current research hotspots. Meanwhile, the optimal coordination of energy in multiple MGs under stable operation has become a highly challenging problem. Taking into account the diversity and complementarity of energy sources within the system, this paper proposes a multi-microgrid (MMG) energy complementation model by fully considering the flexibility characteristics of the supply side, and puts forward a real-time optimization dispatch control strategy based on the model. This strategy takes a completely new approach, based on the characteristics of different types of energy, dividing the dispatch process into two parts to coordinate the energy interactions among multiple MGs, and then determining the optimal dispatching scheme for each part to ensure the autonomous stable operation of individual MG while maximizing the self-sufficiency of the MMG system. At the same time, a case study was conducted on the IEEE 33 node model. Simulation results show that the proposed control strategy achieves the full integration of renewable energy in the MMG system, reduces system operating costs, and achieves the optimal coordination of energy in MMG systems.
