Nonlinear excitation control of power systems with dynamic loads via feedback linearization

This paper presents a nonlinear control design method for interconnected power systems with induction motors as dynamic loads. To design the controller, a feedback linearization technique is used. The control law is applied through the excitation system of the synchronous generator. The designed controller can provide a stable operation of the systems over a wide range of operating region. In this paper, the designed controller is tested on a single machine infinite bus (SMIB) system with dynamic loads. Simulation results show that the control scheme can improve the stability of the system, regardless of operating points
