1. A method for stabilizing disturbances in electric grid currents in a wind turbine energized electric grid, comprising:

  • coupling the stator of a wind driven doubly fed induction generator to the grid;

    coupling the rotor of the doubly fed induction generator to the grid by way of a line side converter, the line side converter comprising a plurality of current conducting electric switches; and

    ,providing the current conducting switches of the line side converter with sufficient current carrying capacity to produce frequency support and increased grid stabilizing currents while providing frequency support and requiring lesser amounts of grid stabilizing currents from the stator of the doubly fed induction generator thereby allowing for increased power producing stator current during disturbances in the electric grid.
