Abstract: For investigating the DFIG-based wind turbine in smart grid; hence, this thesis presents the smart grid of renewable energy aspect, including DFIG wind turbines fault ride-through capability and transient stability improvement. With a device implementation, superconducting fault current limiter (SFCL) by using hightemperature superconductor (HTS) is utilized to improve the fault ride-through capability of the DFIG wind turbines. To describe actual characteristics of the superconductors, thermal subsystem model of the SFCL is applied in this thesis. For improving the fault ride-through capability and transient stability of the DFIG, without the SFCL, the rotor side converter (RSC) controller enhancement, utilizing fuzzy logic voltage regulator, is proposed. Moreover, with increasing of small power plant (SPP) application, the transient stability and fault current reduction of the SPP considering the SFCL recovering times is also demonstrated in this thesis. For reducing the recovery times of the superconductor, a hybrid SFCL consisting the current limiting resistor/reactor (CLR), fast switch, and HTS are utilized for improving fault ride-through capability of the DFIG wind turbines. This thesis also proposes the calculation of current limiting reactance of the hybrid SFCL for enhancing fault ride-through capability of the DFIG wind farm that satisfies grid code requirements. For evaluating the proposed methods to enhance the fault ride-through capability of the DFIGs, the various study cases are examined. As the simulated results on DIgSILENT PowerFactory software, the proposed methods can achieve the fault ride-through improvement meeting the grid code demands.
