Identification of Critical Line in Power Systems Based on Flow Betweenness
摘要
Abstract
Power flow betweenness and its application in vulnerable line identification in the power system are presented. Compared with (weighted) betweenness models in which power flow is supposed to be not directional and transferred only through the shortest path, the presented model bases on current operating mode and flow distribution, can effectively reflect and quantify actual effect of each line by“plant-load” pair with a more comprehensible physical background, in which maximum available transmit power between generator and load is also considered. Meanwhile, to reflect the impact of the critical line fault on the power system, analytic hierarchy process (AHP) is presented to evaluate transmission line over-load , voltage-limit , and transient stability level comprehensively. The Evaluation results are more objective and close to power system characteristics. Numeric examples of the CEPRI36 and Gansu power system show critical line identification method proposed in this paper can better reflect the degree of importance of the line in the entire power grid, and the correctness and effectiveness are verified.关键词
