四川特/超高压电网脆弱度分析及应用

摘要:

在传统电网脆弱性分析基础上，结合特/超高压电网的特点，运用基于复杂网络的结构脆弱性和基于潮流熵 的状态脆弱性理论，对四川特/超高压电网脆弱度进行分析，以此识别四川特/超高压电网的脆弱元件。分析结果表 明: 四川电网具有典型的小世界网络结构特性，同时在不同的运行方式下，四川电网的脆弱节点和脆弱支路会发生转 移，其结果可以为电网的调度运行提供参考。

Abstract:

Based on the vulnerability analysis of the traditional power grid and the features of EHV and UHV power grid，the vulnerability of Sichuan EHV and UHV power grid is analyzed in order to identify the vulnerable components of Sichuan EHV and UHV power grid by using the theory of structural vulnerability based on complex network and the state vulnerability based on power flow entropy． The results show that Sichuan power grid has the typical structural features of small world network，and under the different operating modes，the vulnerable buses and vulnerable branches of Sichuan power grid will shift． The results can provide a reference for the dispatching and operation of power grid．
