A performance oriented wind turbine model for grid stability studies

A generic model of a wind turbine with a double fed generator for grid stability studies is presented. The model takes-off in the required model performance rather than the physical structure and components of the wind turbine. Analysis shows that substantial reductions in model complexity can be achieved by extending some of the basic assumptions for a grid stability model into model simplifications. In spite of large variation in model complexity, a case study in PowerFactory reveals no significant performance variations when the performance oriented model is compared to a far more complex component-oriented model.
