Abstract: A power generation system (101) is disclosed. The power generation system (101) includes a variable speed engine (106) and a DFIG (108) coupled thereto. The DFIG (108) includes a generator (112), a rotor side converter (114), and a line side converter (116) electrically coupled to the generator (112). The rotor side converter (114) is configured to aid in operating the generator (112) as motor to crank the variable speed engine (106). The power generation system (101) further includes a PV power source (110) and/or an energy storage device (122) electrically coupled to a DC-link (118) between the rotor side converter (114) and the line side converter (116). A method of cranking the variable speed engine is also disclosed.
