    Abstract: An uninterruptable power supply (UPS) system for providing power to a load coupled to a utility power source is provided. The UPS system includes a doubly-fed induction generator (DFIG), a rechargeable energy storage system, a first inverter, and a controller in communication with the DFIG and the first inverter. The DFIG includes a stator and a rotor coupled to the load. The stator and rotor are magnetically coupled together. The DFIG generates an auxiliary power output. The first inverter is coupled between the rotor and the rechargeable energy storage system. The controller detects a power disturbance associated with the utility power source and controls the first inverter to provide an excitation input to the rotor in response to the power disturbance. The DFIG provides the auxiliary power output to the load based on the excitation input.

    Abstract: A hybrid power generation system is presented. The hybrid power generation system includes a generator operable via a prime mover and configured to generate an alternating current (AC) power. The hybrid power generation system further includes a first power converter electrically coupled to the generator, where the first power converter includes a direct current (DC) link. Furthermore, the hybrid power generation system includes a DC power source configured to be coupled to the DC-link. Moreover, the hybrid power generation system also includes a second power converter. Additionally, the hybrid power generation system includes an integration control sub-system operatively coupled to the first power converter and the DC power source. The integration control sub-system includes at least one bypass switch disposed between the DC power source and the DC-link and configured to connect the DC power source to the DC-link via the second power converter or bypass the second power converter.
