摘要/Abstract

摘要： 为了提高智能电网中电力光传输网的抗毁性，基于复杂网络理论对南京市江北区电力光传输网进行随机性攻击和选择性攻击实验仿真，根据仿真结果给出提高电力光传输网抗毁性的方法.在随机性攻击实验中分析了单个节点失效对网络连通性能的影响，并对枢纽节点进行了筛选，得到需要重点保护的枢纽节点.在选择性攻击中，提出了网络效率相对损失率优先攻击和实时介数优先攻击策略，并从连通能力、网络效率和网络效率相对损失率三方面进行抗毁性评价.实验结果表明，电力光传输网对实时介数优先攻击的抗毁性最差，由此提出了一种重要节点评估与保护方法以提高电力光传输网的抗毁性，并仿真验证了该方法的可行性和有效性.

Abstract: In order to improve the invulnerability of electric power optical transmission network in the smart grid, experimental simulations of random attacks and selective attacks on electric power optical transmission network in Jiangbei District of Nanjing City are carried out based on complex network theory. A method of improving the invulnerability of the network is proposed according to the simulation results. In the experiment of random attacks, we investigate the impact of single node failure on network connectivity and screen the hub nodes, and get the hub nodes that need to be protected. In selective attacks, two kinds of attack strategies are proposed, namely, network efciency relative loss rate frst attacks and real-time betweenness frst attacks. The invulnerability of the network is evaluated from three aspects including connectivity, network efciency, and network efciency relative loss rate. The experimental results show that the electric power optical transmission network has the worst invulnerability to real-time betweenness frst attacks. On this basis, an important node evaluation and protection method is proposed to improve the invulnerability of electric power optical transmission network, and the feasibility and effectiveness of the proposed method is verifed by the example simulation.

Key words: electric power optical transmission network, smart grid, complex network, invulnerability, important nodes evaluation
