For the phenomenon of low frequency oscillation in the AC-DC interconnected system which contains VSC-HVDC, a method based on H∞ loop shaping is proposed to design the additional robust damping controller. The reduced order model of the system and the related oscillation frequency are identified by total least squares-estimation on signal parameters via rotational invariance techniques. The robust damping controller is designed for the reduced order model of the system based on H_∞ loop shaping and normaliz...
