摘要：在通信受限的情況下如何對低慣量孤島運行的微網同時進行頻率調節和綜合經濟調度，是目前需要解決的難點。建立了含多類型電源虛擬同步機(VSG)的微網調度控制模型，提出了一種集成頻率調節與綜合經濟調度的分布式優化算法，來同時實現微網中的頻率調節和經濟調度。在綜合考慮各類電源 VSG 成本和收益以及微網整體慣量和備用容量需求的基礎上，提出了一個分布式經濟調度問題，該問題最小化了各類型 VSG 參與頻率調節所產生的綜合成本并提高了微網在擾動下頻率的穩定運行能力；在考慮微網逆變器的動態特性的基礎上重構優化問題，利用事件觸發通信在線感知和補償供需失衡，解決了最優調度問題。仿真結果表明，所提方法能夠避免跨時間尺度的層間協調，提高系統的慣量、調頻能力以及經濟性，并增強對短期通信故障的魯棒性。

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
