Key transmission sections play an important role in the security and stability of power system operation and control. An auto-search algorithm of key transmission sections based on complex network theory was proposed, which lays a foundation for the real-time status monitoring and fast analysis of power grid. This method used transmission betweenness indicators to identify the key transmission lines which are determined by the network topology and flow distribution, and it also combined with complex network clustering algorithm to construct subarea division method which was applied to the transmission sections analysis. Based on the subareas, the sufficiency and necessity problem in the auto-search process was solved through characteristics of transmission sections and its relationship with subareas. At last, key transmission sections were ranked according to the transmission betweenness of the leading line, which overcomes the shortcomings of posteriori auto-search method, that is the requirements of the quantitative analysis of the security and stability margin. The analysis results of CEPRI-36 and certain province system verify the validity of the proposed model and algorithm and the adaptability of large-scale power grid.
