基于复杂网络理论的电力信息物理系统耦合建模方式研究与脆弱性分析

Research and vulnerability analysis of coupling modeling method of cyber-physical power system based on complex network theory

对国内外基于复杂网络理论的耦合建模模型进行了梳理和归纳,基于结构熵指标深入分析不同耦合方式下的系统脆弱性,提出一种删除部分不平衡耦合边的保护策略.实验结果表明,耦合的方式极大程度上影响了系统的脆弱性,选择合适的耦合方式对改善系统脆弱性至关重要.

The domestic and foreign coupling modeling models based on complex network theory are sorted out and summarized for subsequent research and analysis.Based on the structural entropy index,the vulnerability of the system under different coupling modes is deeply analyzed,and a protection strategy is proposed to delete some unbalanced coupling edges.The experimental results show that the coupling method greatly affects the vulnerability of the system,and choosing a suitable coupling method is very important to improve the vulnerability of the system.
