| 摘要: |
| 在对比传统电力系统安全性分析与脆弱性分析的基础上,给出了绝对脆弱性、相对脆弱性及灵敏度脆弱性3种典型脆弱性的分析模型.对脆弱性研究的主要方面,如基于能量函数的电压脆弱性和基于复杂网络理论的结构脆弱性进行了分析.指出由于电网是一个强实时非线性的复杂网络系统,单一从节点的运行状态(电压)脆弱强度进行分析,忽略网络整体连接效应,存在一定误差与失真.而单一从网络结构,不考虑运行状态及网络约束,也与电网实际运行相违背.提出构建考虑系统固有脆弱特性、系统运行参数、风险评估及其他可能脆弱因素的综合脆弱性指标. |

| Abstract: |
| Based on the comparison between the traditional security analysis and the vulnerability analysis for the electric power grid,three typical vulnerability assessment models are presented:absolute vulnerability,relative vulnerability and sensitive vulnerability.The main research aspects,such as the energy function based voltage vulnerability and the complex networks theory based structure vulnerability,are analyzed.It is pointed out that,as a real-time nonlinear complex network system,the vulnerability of elec... |
