A power generation system () is presented. The power generation system includes a prime mover (), a doubly-fed induction generator (DFIG) () having a rotor winding () and a stator winding (), a rotor-side converter (), a line-side converter (), and a secondary power source () electrically coupled to a DC-link (). Additionally, the power generation system includes a control sub-system () having a controller, and a plurality of switching elements (, and or ). The controller is configured to selectively control switching of one or more switching elements (, and or ) based on a value of an operating parameter corresponding to at least one of the prime mover, the DFIG, or the secondary power source to connect the rotor-side converter in parallel to the line-side converter to increase an electrical power production by the power generation system. 1100200300400.
