【摘要】：为获得电力网络结构的本质特性,对IEEE标准测试电网和一系列规模不等、发展历程不同、建设水平各异的实际电网,进行复杂网络典型特性分析和结构脆弱性的模拟仿真。分析电力网络节点度数在对数坐标和半对数坐标下的分布特性,探求电力网络特征路径长度、聚类系数的统计特性及其与网络规模之间的关联关系,基于凝聚算法考察电力网络不同模型下的模块度。所分析的电网不具有无标度特性,小世界特性与网络规模相关,而社团特性明显,表明社团特性是电力网络普适的结构特性。以负荷节点可连接的电源节点比例衡量电力网络的整体性能,考察社团间联络线遭蓄意攻击时网络性能的变化。所分析的电网均表现出脆弱性,进一步验证了社团特性是电力网络结构普适的特性这一结论。
[Abstract]:In order to obtain the essential characteristics of power network structure, the typical characteristics of complex network and the simulation of structural vulnerability are analyzed for IEEE standard test grid and a series of actual power grid with different scale, development process and construction level. This paper explores the characteristic path length of power network, the statistical characteristics of clustering coefficients and the relationship between clustering coefficients and network size, and examines the modularity of different power network models based on the agglomeration algorithm. The structure characteristics of power network are universal. The overall performance of power network is measured by the proportion of connected power nodes. The changes of network performance when the inter-community tie lines are deliberately attacked are investigated.
