Zusammenfassung:	This paper proposes a novel double-fed induction generator based wind-energy conversion system (WECS), which incorporates a dynamic voltage restorer (DVR) and energy storage system. The DVR is in series with the output terminal of a wind turbine generator (WTG) and parallel to the dc link of the WTG with the ESS. The control scheme of the WECS is designed to suppress wind power fluctuations and compensate grid voltage disturbances, which in turn improve the fault ride through capability and the wind power penetration level. Finally, the performance of this WECS is investigated under various operation scenarios such as symmetrical and asymmetrical grid faults.
