摘要
为了有效、准确地辨识复杂电网中的脆弱输电线路,本文提出了一种基于结构洞理论的脆弱线路辨识方法。该方法根据N-1安全校验下输电线路分别在拓扑结构和潮流分布上的相关性,衍生出输电线路为节点的双向结构相关性网络和状态相关性网络,进而利用结构洞理论挖掘相关性网络的关键节点,实现复杂电网的脆弱线路辨识。最后,通过对IEEE-39节点算例的测试,验证了本文方法的有效性和准确性。
In order to identify the vulnerable transmission lines effectively and accurately, this paper proposed vulnerable transmission line identification method based on structural hole theory. This method derived bidirectionastructure and state correlation networks respectively taking transmission lines as nodes according to the correspondincorrelations of transmission lines on topology structure and power flow distribution under N-1 security verificatioFurther, the method searched for the crucial nodes based on the structural h ole theory which corresponded to identify thvulnerable transmission lines in complex power grids. Finally, the validity and accuracy of the proposed method werverified by testing on the IEEE-39 bus system.
