Abstract: 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.

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.

Abstract: A power generation system is provided. The system includes a prime mover for transforming a first energy to a second energy. The system also includes an induction generator operatively coupled to the prime mover and configured to generate electrical power using the second energy. The system further includes an inverter electrically coupled to the induction generator for controlling a terminal voltage of the induction generator during a grid-loss condition. The system also includes a power dissipating device operatively coupled to the inverter for dissipating power generated by the induction generator during the grid-loss condition.
