摘　　要：交直流混联电网能够在较大范围内均衡电力系统运行时的潮流,有利于提升新能源大规模接入电网的接入容量及接入范围,是现代电网发展的重要趋势。为分析交直流混联系统的结构脆弱性,避免电网大停电事故的发生,提出一种基于秩和比(RSR)法的电网结构脆弱性分析方法。首先,基于复杂网络结构特性建立脆弱性指标集,其次选用RSR法结合主、客观评价法得到节点脆弱性综合权重值,最后,为验证所提方法的有效性,以EPRI-36节点交直流混联系统为基础算例进行节点脆弱性分析,结果表明该方法具有可行性。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.
