Predictive event‐triggered H ∞ load frequency control for hybrid power systems under denial‐of‐service attacks

In this study, a novel H ∞ predictive event‐triggered load frequency control has been developed for a hybrid power system with renewable energy sources (RESs) to deal with denial‐of‐service (DoS) attacks, where the DoS duration (the time attack lasts) are boundless. A predictive event‐triggered transmission scheme is built for the multi‐area hybrid power systems under DoS attacks to reduce the load of network bandwidth while maintaining adequate levels of performance. Therefore, an observer‐based predictive controller is developed in the presence of both external disturbances and DoS attacks by formulating the LFC problem as a disturbance attenuation issue. In the proposed method, a hybrid power system with RESs is used to achieve novel and better security strategies. Based on the new model, sufficient conditions are obtained using the Lyapunov stability theory to ensure a stable multi‐area hybrid power system with a prescribed H ∞ performance. Moreover, an algorithm is provided to obtain the control strategy of DoS attacks. Finally, the simulation of a hybrid power system with RESs is presented to demonstrate the effectiveness of the proposed method in dealing with the DoS attacks.
