| 摘要: |
| 为了更好地揭示电力通信网络系统特性，基于社团重叠理论与相依网络模型提出一种更符合实际的电力通信网络系统建模方法。分析了实际通信网的网架结构特点，利用点边图转换以及马尔科夫聚类算法对电力网进行社团划分，进而确定社团重叠节点。依据社团重叠节点和相依网络模型建立通信网模型，进而构建了电力通信相依网络系统层级拓扑结构与耦合关系。对IEEE标准算例搭建对应的电力通信网络，基于信息攻击建立电力通信网失效模型，并依据节点损失比例、负荷损失比例、网络相对效率指标进行抗毁性分析。结果表明随着攻击者攻击方式的改进，攻击对系统造成的破坏越大；网络规模的扩大，能够显著提高网络对随机攻击的耐受力；相对于传统建模方法，所建模型更能体现实际电力通信网的抗毁能力。 |

| Abstract: |
| In order to better reveal the characteristics of the power communication network, a more practical modeling method of power communication network is proposed based on the theory of community overlapping and the model of interdependent network. The characteristics of the actual communication network structure are analyzed, the power grid are divided into communities by point-to-edge community transformation and Markov clustering algorithm, and then the community overlapping nodes are determined. In accordance with the community overlapping nodes and the interdependent network model, a communication network model is established and then the hierarchical topology structure and coupling relationship of the power communication interdependent network system are constructed. A corresponding power communication network is set up for IEEE standard examples, and an improved failure model of the power communication network is established on the basis of information attacks. The invulnerability analysis is performed based on the node loss ratio, load loss ratio, and network relative efficiency index. The results show that the damage to the system caused by the attack is worse with the improvement of the attack method, and the expansion of the network scale can significantly improve the network’s tolerance to random attacks. Compared with the traditional model, the proposed model demonstrates the anti-destructive ability of the actual power communication network with high accuracy. |
