Abstract: A power generation system is disclosed. The power generation system includes an engine coupled to a DFIG and a PV power source to supply a solar electrical power to the DFIG (108). The power generation system also includes a controller configured to operate the engine at a first operating speed corresponding to a first determined efficiency of the engine for a first desired level of an engine power in a first operating condition; or operate the engine at a second operating speed corresponding to a desired level of the second electrical power to be absorbed by a rotor winding and a second desired level of the engine power in a second operating condition, wherein the determined first efficiency is substantially close to a first maximum achievable efficiency of the engine. Method of operating the power generation system is also disclosed.
