A power generation system is disclosed. The power generation system includes a doubly-fed induction generator (DFIG) coupled to a variable speed engine and a photo-voltaic (PV) power source. The DFIG includes a generator to generate a first electrical power based at least partially on an operating speed of the variable speed engine. The PV power source may supply a second electrical power to a Direct Current (DC) link between a rotor side converter and a line side converter of the DFIG. The generator and the line side converter are coupled to an electric grid and/or a local electrical load to supply the first electrical power and at least a portion of the second electrical power to the local electrical load.
