In this paper, a nonlinear static var compensator (SVC) controller is proposed to improve power system voltage stability. A third order nonlinear dynamical description for the SVC system is developed and used in the controller design. Adaptive and robust control techniques are employed to deal with both constant and time varying uncertainties in a power system with SVCs. The effectiveness of the controller...
Various nonlinear control techniques have been applied in power system control. The performance of nonlinear controllers is influenced by the parameter uncertainty and external disturbance. This paper will present a novel approach of robust variable structure control (VSC) based static synchronous compensator (STATCOM) controller design for damping multi-mode electrical-mechanic oscillations. The...
This paper illustrates robust fixed order power oscillation damper design for mitigating power systems oscillations. From implementation and tuning point of view, such low and fixed structure is common practice for most practical applications, including power systems. However, conventional techniques of optimal and robust control theory cannot handle the constraint of fixed-order as it is, in general,...
In the last decade, various nonlinear control techniques have been applied in FACTS controller design. The performance of nonlinear controllers is influenced by the parameter uncertainty and external disturbance. This paper mainly discusses a novel approach of robust variable structure control (VSC) based series FACTS controller design for damping local mode power system oscillations. The VSC-based...
