Efficient Energy Management of Multi-Microgrids Systems Based on Distributed Cooperative Control in Autonomous Mode

This paper proposes a real-time optimization based on the cooperative distributed MPC framework to achieve economic and energy dispatch for a neighboring multi-microgrids system in off-grid operation. The optimal control strategy can efficiently manage the microgrids plant using the exchanged information among the microgrids. The idea of coordination is adopted to reduce the gap between the power supply and the user demand using the surplus energy from the nearby microgrids, allowing efficient exploitation of the storage system and renewable energy resources, along with reducing the dependency on the controllable distributed generators. The cooperative control (DMPC-EMS) provides a proper tracking for the customer demand with an optimal and economic scheduling A case study is employed to verify the effectiveness of the proposed approach, the results show the reduction of the operating cost while satisfying the consumer comfort and demand compared to the case where the microgrids operated independently with non-cooperative robust MPC optimization . The simulation results illustrate the efficiency of the proposed method.
