Abstract
An exemplary embodiment includes a wind turbine system. The wind turbine system includes a wind turbine generator operable to supply wind turbine power to a utility system. A converter is coupled to the wind turbine generator and the utility system. The wind turbine system also includes a controller comprising an internal reference frame of the wind turbine generator, coupled to the converter, and configured for modulating flow of power through the converter in response to frequency disturbances or power swings of the utility system relative to the internal reference frame.
Claims12
A system for wind farm management, the system comprising:
- a plurality of wind turbine generators operable to supply wind turbine power to a utility system;
- a plurality of converters, each converter coupled to a respective wind turbine generator and the utility system;
- and
- a controller comprising an internal reference frame of the wind turbine generators and configured for modulating flow of power through the plurality of converters in response to frequency disturbances or power swings of the utility system relative to the internal reference frame, wherein the internal reference frame comprises a variable frequency that is equal to a frequency of the utility system during steady state conditions and that differs from the utility system frequency during frequency disturbances wherein modulating the flow of power comprises providing a supplemental input signal (ΔP) configured to increase or decrease power output of the wind farm.
A system for power management, the system comprising:
- a plurality of distributed generation sources operable to supply power to a utility system;
- a plurality of converters, each converter coupled to a respective generation source and the utility system;
- and
- a controller coupled to the plurality of converters, the controller comprising an internal reference frame of the distributed generation sources, coupled to the plurality of converters, and configured for modulating flow of power through the plurality of converters in response to frequency disturbances or power swings of the utility system relative to the internal reference frame, wherein the internal reference frame comprises a variable frequency that is equal to a frequency of the utility system during steady state conditions and that differs from the utility system frequency during frequency disturbances wherein modulating the flow of power comprises providing a supplemental input signal (ΔP) configured to increase or decrease power output of the system.
