【摘要】：考虑DoS攻击对电力信息物理系统的影响,提出一种电力网络控制系统脆弱节点的检测方法和防御策略,采用分布式控制架构设计传感器和RTU的传输路径.通过求解最稀疏矩阵优化问题,提出一种识别并保护电力通信网脆弱节点和边的方法,保证系统实现安全稳定运行.进一步提出一种可以抵御DoS攻击的电力网络控制系统拓扑设计方法,研究系统遭受DoS攻击时能恢复稳定的电力网络控制系统拓扑连接方式.IEEE 9节点系统用于仿真验证,充分验证了算法的可行性和可靠性,并针对该9节点电力网络控制系统,给出了具体的网络攻击防御策略.
[Abstract]:Considering the influence of DoS attack on power information physical system, this paper presents a detection method and defense strategy for vulnerable nodes in power network control system. The distributed control architecture is used to design the transmission path of sensor and RTU.By solving the most sparse matrix optimization problem, a method to identify and protect the weak nodes and edges of power communication network is proposed to ensure the system to operate safely and stably.Furthermore, a topology design method of power network control system which can resist DoS attack is proposed. The topology connection mode of power network control system, which can restore stability when the system is attacked by DoS, is studied for simulation verification.The feasibility and reliability of the algorithm are fully verified, and a specific network attack defense strategy is proposed for the 9-node power network control system.
