摘　　要：基于柔性互联的微电网集群作为一种新型配电网组网形式,具有高利用效率、低能耗、灵活调控等优势。但传统下垂控制下微网群存在网间频率解耦、运行成本偏高、网间传输功率控制模糊等问题,因此该文提出一种面向智能软开关柔性互联的微网群分布式协调控制策略。首先,建立了微网群双层协调控制架构,上层通过智能体柔性开关实现网间功率交换与成本信息共享,下层根据边际成本信息协调各分布式电源出力灵活经济分配。其次,引入Gossip一致性算法,基于其信息并发传播特性来加速全局信息分享过程;进而提出一种微网群分布式协调控制方法,通过网间智能体柔性开关控制功率流向与网内各分布式电源按边际成本分配功率的特点,实现微网群稳定可靠运行。最后,通过MATLAB/Simulink建立基于柔性互联微网群的仿真模型,验证了所提出控制策略的有效性和适用性。As a novel form of distribution network organization,flexible interconnected microgrid clusters possess ad-vantages 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 coordi-nation 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 flexi-ble 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 ap-plicability of the proposed control strategy.
