Model predictive excitation control for constrained frequency and voltage stabilization

In this paper, a novel controller based on the combination of differential flatness property and model predictive technology for the generator excitation system is proposed. Such controller will maintain the terminal voltage of the generator within physical limits by better utilizing the existing excitation control. This eliminates the need for adding new fast storage. One preliminary real-world system is used to show the effectiveness of the proposed controller, and the results are compared with the performance of earlier proposed high-gain feedback linearizing excitation controller.
