This article determines the order of the converter controls of a doubly fed induction generator (DFIG) wind system in providing damping to the power system. The control hierarchy was established by using the singular value decomposition (SVD) technique. A power oscillation damping (POD) controller was designed in the rotor voltage magnitude control circuit which was observed to be the best candidate. Simulation studies carried out for a number of disturbance conditions including wind gusts indicate that auxiliary control of rotor voltage provides very good damping to the system even in transiently unstable situations.
