Coordinated Tuning of Power System Stabilizer Using Decentralized Modal Control (DMC) Algorithm for Oscillation Damping

D. Jayaraj, K. Vijayakumar

Abstract


This paper presents the method for selecting the power system stabilizer (PSS) parameters. Design of local output feedback power system stabilizer using local signal of the generator (e.g. speed or power) is formulated as a decentralized modal control (DMC) problem. Exact model reduction based on modal control theory is proposed to make the determination of PSS parameters highly efficient. Results obtained from the coordinated tuning of the parameters of power system stabilizers equipped on a SMIB system show that exact assignment of the eigenvalues associated with the poorly damped electromechanical modes can be achieved in a very efficient manner.
