摘要
Abstract
AC-DC hybrid power grid can balance the power flow during the operation of the power system in a large range,which is conducive to improving the access capacity and access range of large-scale access of new energy to the power grid,which is an important trend in the development of modern power grid.In order to analyze the structural vulnerability of AC-DC hybrid system and avoid the occurrence of power grid outage,a rank-sum ratio(RSR)method was proposed to analyze the structural vulnerability of power grid.Firstly,the vulnerability index set was established based on the structural characteristics of the complex networks.Secondly,the RSR method combined with the subjective and objective evaluation method was used to obtain the comprehensive weight value of node vulnerability.Finally,to verify the validity of the proposed method,AC-DC mixed with EPRI-36 node system node vulnerability analysis based on an example,the results show that the method is feasible.关键词
