Abstract: For the physical network, such as power physical network, built cyber network to optimise the regulation and control to constitute cyber-physical system, in order to achieve optimal control of large scale distributed systems, and bring along with virus, hacking, denial of service from the threat of cyber network that may lead to malicious damage in physical system. In this paper, a distributed dynamic model for a class of power systems with data attack is built with the assumption of attack detectability. Dynamic state estimators are presented to detect the attacked data and estimate its original value. Finally, a simulation of 9-bus power system shows the effectiveness of our proposed method.
