摘要：This paper proposes a system using a Superconducting Magnetic Energy Storage (SMES) for smoothen the fluctuation power of the wind turbine (WT) injected to electrical grid, and to enhance the behavior of a WT system during the fault. The Doubly Fed Induction generator (DFIG) has two main problems; first, it is very sensitive to voltage variation, because the stator of DFIG is connected directly to the grid, second is the abrupt variation of the wind velocity causes the fluctuations of the WT output power injected into electrical grid. In order to improve the behavior of the DFIG, to protect the power converter and to smooth the output power fluctuations under faults, an adequate SMES system and it�s control are proposed, The simulations are conducted using the proposed control strategy and the traditional control strategy based on MATLAB/Simulink, The results shown the effectiveness of the proposed control.
