1. A wind turbine comprising a converter which is connected to a generator and injects at least some of the energy generated by the electric generator into an electrical grid, sensors for detecting interference on the electrical grid, and a controller for controlling the converter, wherein the controller is configured to perform a plurality of grid stabilizing functions for counteracting the interference on the electrical grid, to classify the interference, and in the event of detected interference on the electrical grid, to deactivate a portion of the grid stabilizing functions while keeping a remaining portion of the grid stabilizing functions active for counteracting the grid interference as long as interference continues, wherein the classification of the interference is performed using time history of voltage and frequency of the voltage.
