The wind turbine technology has developed rapidly as one of the most mature Renewable Power Generation Technologies. With the advances of power electronic technology, Permanent Magnet Synchronous Generators (PMSGs) have increasingly drawn the interest of wind turbine manufacturers. The increased asset utilization,facilitates the penetration of renewable sources and improves the flexibility, reliability and efficiency of the grid, Superconducting Magnetic Energy Storage (SMES) technology has been progressed SMES technology has the potential to bring real power storage characteristic to protect consumer’s loads from the grid voltage fluctuations during various fault conditions. This project analyses the performance of the PMSG wind turbine under fault conditions by mitigating the voltage fluctuations by making use of SMES based DVR and its design is based on simple PI control method to compensate voltage sags. The performance of the Superconducting Magnetic Energy Storage is validated through simulations using MATLAB SIMULINK and the results reveals that the SMES can be a useful alternative DC source for the DVR.
