A COMPOSITE NONLINEAR CONTROLLER FOR POWER SYSTEMS WITH STATIC SYNCHRONOUS COMPENSATORS UNDER EXTERNAL DISTURBANCES
Keywords:Backstepping control, STATCOM, generator excitation, disturbance observer.
This paper concentrates on the design of a composite nonlinear stabilizing state feedback control for power systems with static synchronous compensator (STATCOM) with a combined improved backstepping strategy and nonlinear disturbance approach. The disturbance observer is employed to estimate unavoidably external disturbances. Thus, the resulting controller enables us to successfully not only stabilize the system stability but also reject undesired external disturbances. To indicate the effectiveness and superiority of the developed process, numerical simulation results are given to show that the proposed composite control law can improve dynamic performances, rapidly suppress system oscillations of the overall closed-loop dynamics, and outperform a conventional backstepping control technique despite the presence of inevitably external disturbances
