Event-based distributed resilient control strategy for microgrids subject to disturbances and hybrid attacks

Abstract

As a typical class of Cyber-Physical Systems (CPSs), microgrids (MGs) are susceptible to malicious cyber attacks and disturbances that can compromise their security and reliability. To address this issue, an event-triggered distributed resilient control method is proposed in this paper to mitigate the impacts of disturbances, FDI and DoS attacks on MGs. The proposed approach employs a piecewise control strategy and utilizes adaptive method to achieve the secondary control objective of MGs. In order to conserve computing and communication resources, an event-triggered mechanism is adopted and its parameter selection is associated with attacks. This design ensures system stability while also eliminating Zeno behavior. By applying Lyapunov stability theory, it can be proven that the algorithm proposed in this paper is capable of achieving the desired control objective. Finally, the effectiveness and superiority of the developed method are demonstrated through simulation examples.
