摘要：This paper proposes a novel scheme to improve the low voltage ride-through (LVRT) capability of the doubly-fed induction generator (DFIG) based wind power (WT). The main problems of DFIG are; its sensitivity to voltage sag in side and the sudden variation in wind speed on the other side, these problems causes the fluctuations in the output power, overcurrent in rotor winding and overshoot in the dc bus voltage. A Hybrid Energy Storage System (HESS) connected in parallel with the rotor side converter of the DFIG, and an adequate control of the HESS are suggested to enhance the DFIG behavior. The simulations is conducting in MATLAB/Simpower system environment, The results show that the proposed scheme can not only enhanced the DFIG behavior under fault, but also smooth the power injected in grid under normal operation with the sudden variation of the wind speed.
