Transient stability enhancement of DC-connected DFIG and its converter system using fault protective device

Journal of Modern Power Systems and Clean Energy, 2017
Transient stability of doubly-fed induction generators (DFIGs) is a major concern in both AC and DC grids, and DFIGs must stay connected for a time during grid faults according to the power grid requirements.
