Dual-channel Dynamical Event-Triggered Load Frequency Control under Attack for Wind Power Systems with Multiple Time-varying Delay

In order to stabilize a multi-time-delay interconnected wind power system, a dual-channel dynamic event-triggered load frequency control scheme is proposed, considering network attacks in this paper. Firstly, this paper designs load frequency control of wind power system incorporating the effect of time-varying delay both in the states and control input. Secondly, in order to reduce the occupancy of communication bandwidth, a novel transmission scheme with two asynchronous event triggers network channels has been designed. Further, a malicious bounded time-delay deception attack model is proposed to enhance the security. By constructing a discrete-type Lyapunov-Krasovskii functional, stability criteria with H

performance index are established. Finally, numerical examples are presented to demonstrate the effectiveness of the proposed control method.
