摘　　要：为科学有效地确定稳控系统布局、精准识别分区断面,提升大规模电网运行的安全性,提出一种基于复杂网络耦合矩阵的电网分区方法。首先,基于电网潮流及无功-电压灵敏度构建电网复杂网络耦合矩阵,以表征有功运行特性和电压控制特性,实现有功、无功权重的双重量化;然后,建立电网分区质量的评价指标,量化分区结构强度、源荷匹配程度和调压控制效果,形成电网区域划分的结构性和功能性评价体系;最后,考虑电网实际运行特性与拓扑结构特征,对复杂网络理论的局部拓展算法进行适应性改进,以实现电网的非重叠最优区域划分。算例分析验证了所提分区方法的优越性和准确性。To scientifically and effectively determine the layout of stability control systems,accurately identify parti⁃tion interfaces,and enhance the operational security of large-scale power grids,this paper proposes a power grid partitioning method based on complex network coupling matrices.First,a complex network coupling matrix is con⁃structed using grid power flow and reactive power-voltage sensitivity to represent active operation and voltage control features for dual-weight quantification of active and reactive power.Next,quality evaluation metrics for grid parti⁃tioning are developed to quantify partition structure strength,source-load matching,and voltage regulation effects,forming a structural and functional evaluation framework for grid partitioning.Finally,considering the grid’s opera⁃tional characteristics and topological features,the local expansion method of complex network theory is adaptively improved to achieve non-overlapping optimal grid partitioning.Case analysis validates the superiority and accuracy of the proposed method.
