Design of Damping of Power System Oscillation usingSTATCOM With Energy Storage

Abstract

The motto of present paper is to find out theenhancement of damping the power system oscillationthrough co-ordinated model of ‘Static SynchronousCompensator’ (STATCOM) situated in shunt withtransmissionline.side.Thisisachieved using a signal estimation technique based on a modifiedrecursive least square (RLS) algorithm, which allows a fast,selective, and adaptive estimation of the low-frequency electromechanical oscillations from locally measured signals duringpower system disturbances. The proposed method is effective inincreasing the damping of the system at the frequencies of interest,also in the case of system parameter uncertainties and at variousconnection points of the compensator.
