This paper proposes a new control strategy for a DFIG operating in an isolated power system, accomplished by a Dynamic Voltage Restorer (DVR) and a Supercapacitor Energy Storage System (SCESS), in order to ride through symmetrical and asymmetrical faults. During faults, the DFIG continues to operate normally, while the active power mismatch is handled by the SCESS. In particular, during asymmetrical faults, the DFIG and the DVR are properly controlled in order to feed the non-faulty phases uninterruptedly. When integrated in a power system with conventional synchronous generators, the proposed control strategy improves the Fault Ride-Through (FRT) capabi ...
