This article investigates the event-triggered observer-based output feedback load frequency control (LFC) problem for power systems. To reduce the amount of the transmitted signals, a dynamic event-triggered scheme is proposed by adding an exponential term. Moreover, an adaptive event-triggered scheme is proposed to provide a balance between the control performance and the number of the transmitted signals. Under the proposed schemes, a new model is formulated for the observer-based output feedback LFC system via a time-delay system method. By employing the Lyapunov functional method, sufficient conditions are derived for global asymptotical stability and Lperformance. Then, a controller design method is developed. Finally, two examples are given to illustrate the effectiveness of the proposed schemes.
