[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.
