“…In [43], an attackresilient event-triggering mechanism was proposed for a nonlinear DC microgrid system subject to intermittent DoS attacks where the DoS frequency and DoS duration were characterized in the stability criterion. As compared to [43], the system modeling in our proposed approach is different and moreover importantly both current sharing and voltage regulation in the DC microgrid are considered. The stability analysis approach in our paper is different from [44].…”

In this paper, the problem of distributed event-based control of large scale power systems in presence of denial-of-service (DoS) cyber attacks is addressed. Towards this end, a direct current (DC) microgrid composed of multiple interconnected distributed generation units (DGUs) is considered. Voltage stability is guaranteed by utilizing decentralized local controllers for each DGU. A distributed discrete-time event-triggered (ET) consensus-based control strategy is then designed for current sharing in the DGUs. Through this mechanism, transmissions occur while a specified event is triggered to prevent unessential utilization of communication resources. The asymptotic stability of the ET-based controller is shown formally by using Lyapunov stability via linear matrix inequality (LMI) conditions. The behavior of the DGUs subject to DoS cyber attacks are also investigated and sufficient conditions for secure current sharing are obtained. Towards this end, a switching framework is considered between the communication and attack intervals in order to derive sufficient conditions on frequency and duration of DoS cyber attacks to reach the secure current sharing. The validity and capabilities of the presented approach is confirmed through a simulation case study.INDEX TERMS Distributed event-based control, denial-of-service (DoS) cyber attack, DC microgrid, current sharing, asymptotic stability, consensus-based control, linear matrix inequality (LMI).

Measuring resiliency of smart grid systems is one of the vital topics towards maintaining a reliable and efficient operation under attacks. This paper introduces a set of factors that are utilized for resiliency quantification of microgrid (MG) systems. The level of resilience (LoR) measure is determined by examining the voltage sag percentage, the level of performance reduction (LoPR) as measured by percentage of reduction of load served, recovery time (RT), which is the time system takes to detect and recover from an attack/fault, and the time to reach Power Balance state (Tb) during the islanded mode. As an illustrative example, a comparison based on the resiliency level is presented for two topologies of MGs under an attack scenario.

“…To improve the utilization of network resources, event-triggered control strategies have been developed, for instances, [21] constructed an event-based sampling strategy, in which the control input was updated only at a bunch of discrete time instants; [22] considered the nature of digital information and proposed a novel event-triggered mechanism (ETM) with periodic sampling behaviors. These approaches have inspired a massive amount of outcomes [23][24][25][26][27] and the reference therein. In recent years, great efforts have been made to improve the ETMs.…”

We address the resilient event-based control of nonlinear cyber-physical systems subject to deception attacks. In particular, an improved Takagi–Sugeno (T-S) fuzzy model is employed to solve the mismatch problem between the fuzzy system and fuzzy controllers. From the attacker's point of view, we construct a novel queuing model to depict the intermittent behaviors of deception attacks. Then, a resilient event-based communication scheme is proposed, which is dynamically switched with different attack modes. The idea is to appropriately reduce the number of triggers according to the severity level of attacks, which can further save network resources. By using piecewise Lyapunov functional methods, we find a solution to the co-design of fuzzy controllers and event-triggering parameters while the concerned system is guaranteed to be exponentially stable. Finally, we apply the proposed approaches to a mass–spring–damping system, where the effectiveness is well verified.
