Summary: This study investigates observer-based predictive event-triggered load frequency control (LFC) for a multi-area power system in a smart grid with electric vehicles (EVs) under denial-of-service (DoS) attacks. By developing an event-triggering scheme based on the observer and presenting a model-based predictive control approach, stability under consideration of long-duration DoS attacks and external disturbances was derived.

Summary: In this paper, a resilient load frequency control (LFC) design method is proposed for multi-area power systems under a new class of time-constrained denial-of-service (DoS) attacks. A time-varying Lyapunov function (TVLF) approach, which is dependent on the attack parameters, is developed to enable a resilient LFC design without compromising system stability and performance. The minimum allowable sleeping period and the maximum allowable active period of the attacked LFC system can be explicitly disclosed. Two simulation case studies are presented to demonstrate the effectiveness of the proposed approach.

Summary: This article proposes two update strategies based on event/self-triggering for control protocols to handle the leader-following consensus in unreliable shared networks against denial-of-service (DoS) attacks. The strategies include a dynamic event-triggered communication scheme to mitigate unnecessary information transfer and a self-triggered communication function to save computation resources. The effectiveness of the proposed strategies and control protocols is verified through simulations.

Summary: This paper develops an adaptive memory-based event triggering resilient LFC approach for multi-area power systems with wind power, considering denial-of-service (DoS) attacks in the communication network. The impact of each DoS attack is evaluated by the amount of continual information loss it causes, and an adaptive memory event triggering mechanism (AMETM) is proposed. A sampling-data LFC model is established based on the proposed AMETM and DoS attacks. The exponential stability criterion and the memory controllers design method are obtained to ensure the proposed memory control scheme can quickly stabilize the LFC system under a longer DoS attack.

Summary: This paper presents a decentralized resilient H-infinity load frequency control (LFC) scheme for multi-area cyber-physical power systems (CPPSs) under DoS attacks. State-feedback controllers are designed using a novel transmission interval-dependent loop functional method to ensure system performance and resilience index. The proposed scheme achieves less conservative H-infinity performance and resilience index for the LFC system.

Summary: This article investigates the resilient control for networked control systems in the presence of denial-of-service (DoS) attacks using a sampled-data and dynamic quantization scheme. A novel dynamic quantization strategy is designed for signal transmissions in the presence of DoS attacks. An estimator is introduced to design control laws and sufficient conditions are provided for the asymptotic stability of the system. An event-triggered communication scheme is also designed to reduce network resource consumption.

Summary: This paper proposes a co-estimation and resilient compensation control framework for multi-area load frequency control (LFC) systems in the presence of false data injection (FDI) attacks and denial-of-service (DoS) attacks. The paper introduces a new DoS attack model and constructs switching impulsive and state observers for estimating the unknown attack signal and system state. The paper also derives a new stability criteria for the LFC systems under DoS and FDI attacks, and develops a co-design method for attack compensation controller, state estimator, and attack estimator. Case studies are conducted to verify the effectiveness of the proposed theoretical results.
