چکیده

This paper presents the complete modeling and real-time simulation of wind turbine driven doubly-fed induction generator (DFIG) which feeds ac power to the utility grid. For that, two pulse width modulated voltage source converters are connected back to back between the rotor terminals and utility grid via common dc link. It is found that there are so many limitations in the conventional control techniques of DFIG. This paper presents a configuration of a DFIGbased wind Energy Conversion system (WECS) with a battery energy storage system (BESS) in the dc link with a control strategy to maintain the grid power constant. This proposed control strategy then Simulated in Matlab-Simulink. Simulation results show that the proposed strategy can enhance the performance of the DFIG.
