Abstract: A system for controlling a hybrid power generation plant is provided. The system is programmed to receive current conditions at the plurality of power generating assets including a first asset type and a second asset type, determine a forecast for a period of time based at least in part on the current conditions, determine that a first asset of the first asset type of the plurality of power generating assets has an available uprate margin for production of a first amount of active power, determine that a second asset of the second asset type of the plurality of power generating assets has capacity to generate a second amount of reactive power, instruct the first asset to reduce production of reactive power by the second amount and increase production of active power by the first amount, and instruct the second asset to increase production of reactive power by the second amount.

Abstract: A power generation system (100, 200, 300, 400) is presented. The power generation system includes a prime mover (102), a doubly-fed induction generator (DFIG) (104) having a rotor winding (126) and a stator winding (122), a rotor-side converter (106), a line-side converter (108), and a secondary power source (110, 401) electrically coupled to a DC-link (128). Additionally, the power generation system includes a control sub-system (112, 212, 312) having a controller, and a plurality of switching elements (130, and 132 or 201). The controller is configured to selectively control switching of one or more switching elements (130, and 132 or 201) 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.
