Abstract :
This paper examines the effects of noise on the adaptive damping of low-frequency oscillations in power systems. Recursive extended least squares (RELS) is incorporated in a self-tuning adaptive controller which uses an enhanced linear-quadratic control algorithm. Simulation results are presented to demonstrate the effectiveness of the controller in a noisy power system environment. These results demonstrate that recursive extended least squares (RELS) can be beneficial to adaptive damping by determining colored noise parameters in addition to system parameters
