Abstract :
The design and performance of two nonlinear controllers for power systems is explored in this paper. The designs are based on nonlinear discrete-time predictive control and feedback linearizing control, considering a simplified nonlinear single-machine infinite bus (SMIB) power system model equipped with a series-capacitor controller. Simulations are presented for nonideal conditions such as bounded control, the uncertainties in the chosen model parameters, and the presence of inter-area-type persistent disturbances. The results indicate that superior performance can be obtained using the nonlinear predictive controller when compared with the feedback linearizing controller and a standard linear quadratic regulator
