Abstract

This paper concentrates on performance evaluation and comparison of CONVENTIONAL CONTROLLERS such as Mechanically Switched Capacitor (MSC), Load Tap Changer (LTC), Power System Stabilizer (PSS), and FACTS CONTROLLERS such as Static Var Compensator (SVC), Thyristor Controlled Series Capacitor Power Oscillation Damper (TCSC POD) controller and Unified Power Flow Controller (UPFC) in mitigating CHAOS driven instabilities such as voltage and angle instabilities. The CHAOS is triggered by the nonlinearities associated with high gain fast excitation system of automatic voltage regulator (AVR) and shunt capacitors. The instability problem is explored by invoking bifurcation theory. Bifurcation diagrams of steady state as well as periodic solutions are plotted. From the bifurcation diagrams, the existence of various bifurcation points such as, Hopf Bifurcation (HBF), Saddle Node Bifurcation (SNB) and Period Doubling Bifurcation (PDB) are identified. With the use of tools of nonlinear dynamics, voltage collapse points, chaotic solutions due to period doublings and CHAOS divergence points are unearthed. Comprehensive comparisons of the effectiveness of the controllers are presented from the point of view of delaying HBF, SNB and increasing the loadability limit.
