摘　　要：针对电力系统结构脆弱性问题,利用多指标评价优势,结合Pajek工具识别电网关键节点。首先,基于复杂网络理论,综合考虑电力网络的拓扑特性,建立电力系统结构脆弱性综合评价指标集。其次,在评价方法上,采用模糊综合评价法和CRITIC法分别计算各项评价指标的主、客观权重。最后,提出VIKOR综合评价法来计算各节点权重值并得到重要度排序结果。以IEEE-118系统为例并与其他评价法对比分析,结果表明所提方法有效。Aiming at the problem of power system structure vulnerability, the advantage of multi-index evaluation can be combined with Pajek tool to identify the key nodes of power grid. First of all, based on the complex network theory, considering the power network topology characteristics, structural vulnerability evaluation index system of integrated power system was established. Secondly, in terms of evaluation methods, fuzzy comprehensive evaluation method and CRITIC method were used to calculate the subjective and objective weights of each evaluation index. Finally, combination weighting VIKOR was proposed to calculate the weight value of each node and obtain the ranking result of importance. Taking IEEE-118 system as an example and comparing with different evaluation methods, the results show that this method is feasible.
