摘要:

文章基于复杂网络理论,将智能电网抽象为由节点、边构成的拓扑网络结构,分别从仿真网络构建和网络攻击仿真模拟两个方面建立了基于复杂网络理论的智能电网网络攻击仿真流程。首先,构建仿真网络并分析仿真网络节点度分布和节点度数累积概率分布情况,得出该网络为无标度网络的结论。其次,进行网络攻击仿真模拟,设置两种攻击情形,分别为针对智能电网全部网络节点进行随机攻击(情形1)和针对智能电网网络中度数大于最大度数80%的节点进行攻击(情形2),通过对比分析两种攻击情形中的网络聚类系数、平均度、平均路径长度的变化特征,得出在对网络聚类系数的降低方面,情形1的作用小于情形2的作用;在平均度变化和网络平均路径长度影响方面,情形1的影响高于情形2。

Abstract:

Based on the complex network theory, this paper abstracts the smart grid into the topological network structure composed of nodes and edges, and establishes the simulation process of smart grid network attack based on the complex network theory from the two aspects of simulation network construction and network attack simulation. Firstly, the simulation network is constructed and the distribution of the node degree and the cumulative probability distribution of the node degree are analyzed. It is concluded that the network is a scale-free network. Secondly, perform network attack simulation and set up two attack cases, namely, random attacks against all network nodes in the smart grid (case 1) and attacks against nodes with a degree greater than 80% of the maximum degree in the smart grid network (case 2). By comparing and analyzing the changing characteristics of the network clustering coefficient, average degree, and average path length in the two attack cases. It is found that the effect of case 1 is smaller than the effect of case 2 in reducing the network clustering coefficient. In terms of the average degree change and the average path length of the network, the impact of case 1 is higher than case 2.
