Abstract :
The increasing wind power penetration poses significant technical problems for the electric power systems. The intermittent and fluctuant output power of wind generators has a great impact on the power quality and power system stability. On the other hand, the grid-side faults influence the transient processes of wind generators. In this paper, an integrated control strategy is proposed based on the characteristics of directly driven wind turbine with permanent magnet alternator (D-PMA). The D-PMA is incorporated with energy storage system, which smoothes the output power and enhances the low voltage ride-through (LVRT) capability of the wind generator. The effectiveness of the control strategy has been verified in the numerical simulations.
