  4. Abstract:
  5. Fast growth of wind power generation and its contribution in power systems dynamic performance has highlighted the importance of developing generic models for wind turbines. Following the former efforts, an enhanced version of standard generic wind turbine model is proposed in this article. The enhancements are aimed to make the model applicable for unbalanced Root Mean Square (RMS), short-Term frequency stability, and low-voltage ride-Through (LVRT) studies. Moreover, fidelity of the overall responses of the model is increased. To achieve these goals, five new blocks are designed and added to the base model and three existing blocks are modified. The new blocks are negative-sequence generator/converter model, inertial controller, LVRT controller, dc-link and the Line Side Converter (LSC), and the natural flux models. Responses of the enhanced model are compared with the results of both the base model and a detailed model, and validity of the proposed model is verified by different transient scenarios. © 2010-2012 IEEE
