Modeling and investigation of fault ride through capability of variable speed wind turbines

Recent technological improvements on wind energy systems and the incentives provided by the governments have increased the penetration level of wind power into the grid. This phenomenon force the transmission and distribution system operators to revise their grid codes. Moreover, these developments force the wind turbines stay connected to the grid during the disturbances in order to enhance system stability. This work is devoted to the modeling of variable speed wind turbines and the investigation of fault-ride through (FRT) capability of wind turbines for grid integration studies.
