摘要

综合电网的输电关系、拓扑结构和运行状态，提出了电力间的概念。根据网络连通性和输电分配，分别定义了传输线和节点的功率间隔。通过对关键传输线的破坏、过载等级联攻击，对选定的关键传输线进行有效性验证。以IEEE 39总线系统为例，对传输线间功率和节点间功率进行了计算和排序;根据排序结果，对这些元素进行攻击，验证这些具有高功率间隔的元素确实是电网中的薄弱环节。利用网络效率函数和潮流熵分别对静态攻击下的稳定性进行验证。验证结果表明，电气元件的功率间隔越大，攻击对电网运行的影响越大。

Power Betweenness Based Identification of Power Grid Critical Links

Synthesizing power transmission relation, topological structure and operational status of power grid a concept of power betweenness is proposed. According to network connectivity and the allocation of power transferring, the power betweenness of transmission line and that of node are defined respectively. Through the cascading attacks such as the breakage or overload on critical transmission lines, the effectiveness validation of the selected critical transmission lines is performed. Taking IEEE 39-bus system as the testing example, the power betweenness of transmission lines and that of nodes are calculated and sorted; according to sorted results, attacks are made on these elements to verify that these elements with high power betweenness are the weak links in power grid indeed. The stability verification under the static attack is performed by network efficiency function and power flow entropy respectively. Verification results show that the higher the power betweenness of electric element is, the greater the attack affects power grid operation.
