Abstract: As a novel form of distribution network organization, flexible interconnected microgrid clusters possess advantages such as high utilization efficiency, low energy consumption, and flexible regulation and control. However, microgrid clusters under traditional droop control face issues such as inter-grid frequency decoupling, high operational costs, and ambiguous control over inter-grid transmission power. Therefore, this paper proposes a distributed coordination control strategy for microgrid clusters with intelligent soft switches for flexible interconnection. Firstly, a two-tier coordination control framework for microgrid clusters is established. The upper tier facilitates inter-grid power exchange and cost information sharing through intelligent flexible switches, while the lower tier coordinates the flexible and economic allocation of output power among distributed energy resources (DERs) based on marginal cost information. Secondly, the Gossip consensus algorithm is introduced to accelerate global information sharing based on its concurrent information dissemination characteristics. Subsequently, a distributed coordination control method for microgrid clusters is proposed, which achieves stable and reliable operation of the clusters by controlling power flow through inter-grid intelligent flexible switches and allocating power within the grid based on marginal costs among DERs. Finally, a simulation model of flexible interconnected microgrid clusters is established using MATLAB/Simulink, validating the effectiveness and applicability of the proposed control strategy.
