摘要
提出考虑多因素的电网关键线路主客观综合辨识方法——从电网拓扑结构以及运行状态角度出发,建立子指标体系,针对以往研究没有深入考虑各个子指标在关键线路辨识过程中地位和作用的问题,利用层次分析法确定各子指标主观权重,利用熵权法确定客观权重,在综合考察主客观权重的基础上,构建关键线路的综合辨识指标。最后利用IEEE39节点系统为例进行分析,与研究成果进行比较,说明该方法的合理性和可靠性。
This paperpresents a subjective and objective comprehensive identification method for power grid critical lines considering multiple factors which is to establish a sub-index system based on power grid topology structure and operational state. In allusion to the problem of past research not considering position and function of each sub-index in identifying critical lines, it uses analytical hierarchy process （AHP） to determine subjective weight of each sub-index and entropy-right method to confirm objective weight. On the basis of comprehensively investigating subjective and objective weight, it constructs comprehensive identification index for critical lines. By taking IEEE39 node system for an example, it analyzes and compares research results, and proves reasonability and reliability of this method.
