Abstract: A method for operating a power generation system is presented. The method includes estimating, by a controller, at least one of a required load and input power of the doubly-fed induction generator for a pre-determined future time duration. The method includes comparing, by the controller, the estimated at least one of the required load and the input power with a corresponding threshold value. Moreover, the method includes transitioning, by the controller, operation of the power generation system from a partial power conversion mode to a full power conversion mode by controlling switching of one or more of a plurality of switches if the estimated at least one of the required load and the input power is less than the corresponding threshold value, wherein the plurality of switches includes a first set of switches coupled to stator winding of the doubly-fed induction generator.
