Improved Synchronism In DFIG Wind Energy Conversion System Using SMES Energy Storage

The use of Wind Energy for Electrical Power generation has increased considerably over past few decades and emphasis is continuously given for its integration with power grids. It has been found difficult to keep doubly fed induction generator (DFIG) connected to grid under various dynamic conditions like Fault, etc. One of the most important parameters of the system where wind turbine generators (WTGs) are connected is voltage profile at the point of common coupling (PCC). Superconducting magnetic energy storage (SMES) can improve the dynamic performance of a wind turbine equipped with DFIG during voltage sag and swell events. The converter and the chopper of the SMES unit are controlled using a hysteresis current controller (HCC) and a fuzzy logic controller (FLC), respectively. Detailed simulation will be carried out using MATLAB/SIMULINK software to highlight the impact of the SMES unit in improving the overall system performance under voltage profile.
