摘　　要：多微网孤岛划分对辅助多微网并离网运行协调控制策略、提高多种运行模式下电压稳定水平具有重要意义。基于戴维南等效的电压稳定裕度,提出一种新孤岛划分方法,利用CIGRE中压网络进行算例分析;结果表明,新划分方法在电压稳定性、负荷保留量等指标均优于传统方法。Island partitioning of multi-microgrids is significant in assisting coordinated control strategies of multi-microgrid islanding and reconnecting to the main grid, and in improving voltage stability under various operating modes. Based on Thevenin equivalent voltage stability margin, this paper presents a new method for island partitioning which uses the CIGRE MV network for example analysis. The results indicate that the new partitioning method is superior to the traditional method in the respects of voltage stability, allocated load inventory, etc.
