TL;DR: In this paper, a reduced-order DFIG model is developed that restricts the calculation to the fundamental frequency component and allows the consideration of the alternating components of the rotor current as well, which is necessary for triggering the crowbar operation.

TL;DR: In this article, the authors summarized the work of the Ad Hoc Task Force on Wind Generation Model Validation, and made recommendations on the path forward for wind turbine generator modeling and model validation, primarily focused on generic models for stability analysis in power system studies.

TL;DR: In this paper, a method for operating at least one wind turbine with a rotor and an electric generator coupled to the rotor for delivering electrical power into an energy distribution system with the aid of a control device ensures that the wind turbine operates within its operating range.

TL;DR: In this article, the effect of the violation of this stability limit during fault on the wind park has been analyzed using sample computations, and a control scheme has been proposed, which on the basis of the voltage dip experienced by the network, reduces the real part of wind park output current with the objective of enhancing the transient stability margin.

TL;DR: In this article, the authors present a comprehensive review of the work done in this field, based on the results obtained by IEC and WECC working groups in the course of their research, which have motivated the publication of the IEC 61400-27 in February 2015.
