Abstract :
With the distributed power generation systems such as wind becoming more and more widely spread, it takes great risks to the grid. It is required that the wind turbines should remain connected to the grid and actively contribute to the system stability during and after grid faults. This paper deals with taking advantage of energy storage to improve the low-voltage ride-through (LVRT) capability in doubly fed induction generators (DFIG). And simulation results verified the effectiveness of super capacitor (SC) storage in limiting the dc-link voltage fluctuations and improving LVRT capability.
