Abstract

Cyberphysical systems have achieved rapid development over the past decade due to their widespread applications in various domains, and are typically composed of sensing, communication, computing, and actuation capabilities. However, the communication network of physical security systems may be attacked by cyber attacks, which significantly destroys the performance of the system. Recently, DOS denial-of-service attacks (1) have attracted a lot of attention. In this article, a solution to deal with DoS attacks on the power sharing control system of the electrical energy distribution network, including distributed generation, is presented. So that a time-varying distributed estimator has been used. Based on the feature of service interruption communication duration, the convergent design conditions of observer parameters are obtained using Lebag2 integral theory and average dwell time method. It is also shown that the observer errors converge. Finally, the presented coping method is placed on the virtual impedance control line 3 of the power sharing control system and will neutralize service interruption attacks
