Method to suppress sub-synchronous oscillation of DFIG-based wind farms based on virtual impedance

Content Provider	IET Digital Library
Author	Ning, Wei Wu, Xi Guan, Ya Jing Chen, Fan
Abstract	This study proposes a novel method that can mitigate sub-synchronous oscillation in the wind farm by adding virtual impedance controller to the rotor side converter (RSC) of doubly-fed induction generator (DFIG). Firstly, the transfer function of RSC is obtained, taking into account the structure of outer voltage loop in RSC and virtual impedance controller. Then, the design procedure of virtual impedance controller is converted into an optimisation problem for maximising the absolute phase of this transfer function at the resonance frequency. Also genetic algorithm is utiliesd to obtain the optimal parameters of controller. Both the frequency-domain analysis of this transfer function and time-domain simulation have validated the effectiveness of this optimal parameters, and the superiority of virtual impedance controller is compared with virtual resistance controller finally.
