摘要：The micro-grid system is a typical cyber-physical system. It is not only a combination of physical devices such as power generation, distribution, transmission and consumption, but also a networked multidimensional complex system integrating computing, communication, storage, real-time sensing, dynamic control and energy transmission. Therefore, the security control of the cyber-physical micro-grid system has become a key issue to be studied under the renewable energy development situation. This paper mainly studies malicious time-delay attack (TDA). Firstly, a cyber-physical micro-grid framework with energy storage devices and TDA is presented and a hierarchical control structure is used. Secondly, a new interval time-varying delay stability criterion based on Lyapunov-Krasovskii Functional (LKF) with cubic polynomial of delay is proposed. Finally, the simulation verifies that the proposed delay-dependent stability criterion is less conservative, and the delay margins corresponding to different control parameters are obtained. ? 2023 IEEE.
