Abstract: In this paper the optimization problem of tuning of lead-lag Power System Stabilizer (PSS) for damping of oscillations in single machine infinite bus power system with multiple design requirements is considered. The design requirements are considered as both time domain and frequency domain specifications which are initially specified before designing the PSS. The optimization based linear control design technique is used to determine the optimal controller parameters. The stabilizer contributes to the electro mechanical torque components without affecting the synchronizing torque in the system. The proposed design of power system stabilizer is tested for various disturbance conditions for damping of oscillations while satisfying the design requirements.
