Wind turbines are rapidly increasing and some times are disconnected from the grid intentionally or inadvertently and continue to supply local loads. If it was decided to reconnect to the grid, some problems may happen. This paper deals with the reconnection of islanded wind turbines to the grid and proposes a new method to reduce the high current effects of reconnection. The new method is simple and do not need any synchronization devices, especially for asynchronous wind turbines in which synchronizers are not practical. The simulation results done by MALAB affirm the validity of the proposed method.
