Abstract

This contribution discusses and compares different control techniques for damping undesirable electromechancial oscillations in power systems by means of power system stabilizer and Series / Shunt FACTS controllers. The linearized model of the power system is derived with FACTS controllers and the problem of small signal stability enhancement is formulated as an optimization problem to maximize the damping ratio of critical electro mechanical modes in the power system. Particle swarm optimization (PSO) technique is applied to tune the controller parameters of the PSS and FACTS controllers. The following FACTs controllers are taken for analysis (i) Static Var Compensator (SVC) (ii) Static Compensator (STATCOM) (iii) Thyristor Controlled Series Capacitor (TCSC) (iv) Unified Power Flow Controller (UPFC) .
