The functionality of electric power network are continuously challenged by dynamic and diverse disruptions. The vulnerability analysis in the context of resiliency, using complex networks has significantly modified in the past few years, enlighten valuable ideas to examine the structural, topological and constructional behavior of a power transmission network. This network having similarity with graph theoretic approach in accordance with complex graph theory. Vulnerability is assessed in this paper by evaluating betweenness and netability for topological analysis of vulnerability. Undesirable high impact low occurrence events result in disruption of a large power network as well as to the whole grid. Framework of resiliency in this paper is done in conceptual long-term basis and vulnerability assessment approach. Simulation carried out in this paper to realize the assessment of vulnerability using netability. The considered test system is standard IEEE 14 bus system. One FACTS device, namely STATCOM is employed to the system to show the improvement in the steady state bus voltage.

不断变化的动态变化不断挑战着电力网络的功能。在过去的几年中，使用复杂网络对弹性进行脆弱性分析已进行了重大修改，启发了宝贵的思想来研究输电网络的结构，拓扑和构造行为。该网络与根据复杂图论的图论方法具有相似性。本文通过评估脆弱性的拓扑结构之间的中间性和可网络性来评估脆弱性。不良的高影响低发生事件会导致大型电网以及整个电网的中断。本文的复原力框架是以概念性的长期基础和脆弱性评估方法完成的。本文进行了仿真，以利用网络实现对漏洞的评估。所考虑的测试系统是标准的IEEE 14总线系统。一种FACTS器件，即STATCOM被用于该系统，以显示稳态总线电压的改善。
