    Abstract: In the case of limited communication, how to carry out frequency regulation and comprehensive economic dispatch of microgrids operating in low inertia islands at the same time is a difficult point to be solved. In this paper, a microgrid dispatch control model establishment of virtual synchronous generator (VSG) a distributed optimization algorithm integrating frequency regulation and integrated economic scheduling is proposed to realize frequency regulation and economic dispatch in microgrid at the same time. A distributed economic dispatching problem that based on a comprehensive consideration of the costs and benefits of VSG of various power sources and the overall inertia and reserve capacity requirements of microgrids, minimizing the comprehensive cost caused by various VSG types participating in frequency regulation and improves the stable operation capability of microgrid under frequency disturbance. The optimal dispatch problem is then solved by considering the dynamic characteristics of microgrid inverters, the optimization problem is reconstructed, and bying event-triggered communication online perception and compensation for supply and demand imbalances. The simulation results show that the proposed method is able to avoid interlayer coordination across time scales, improve the inertia, frequency regulation ability and economy of the system, and enhance the robustness to short-term communication faults.
    Key words: virtual synchronous generator; frequency regulation; economic dispatch; distributed optimization algorithm; isolated island microgrid
