Abstract :
In this work the model of different parts of the wind energy conversion system using doubly-fed induction generator (DFIG) is set up and implemented in PSCAD/EMTDC. The two quadrants DC converter using battery energy storage system is employed for the DC-Link Voltage control in normal and fault operating conditions. To verify the control strategies and Low Voltage ride through (LVRT) capabilities a 600 KW DFIG Wind turbine system under 500 ms short circuit fault is tested. Finally, it is proved that the use of battery energy storage system (BESS) improves the power quality during the normal operation and enhances the turbine security level in the grid connected under fault conditions and quickly brings back the stability of the system.
