  • Dynamic adjustment of power plant output based on electrical grid characteristics
    Patent number: 8704390
    Abstract: Method, power plant, and computer program product for use in controlling power output by a power plant. The power plant includes a wind farm with a plurality of wind turbines, a grid power converter (such as one or more HVDC links), a sensor to measure the frequency of a power grid, and a supervisory controller. The supervisory controller implements a control algorithm that adjusts the power output from the power plant in response to the frequency of the power grid dropping below a first target frequency by changing the pitch of the blades of at least one wind turbine, increasing the level of a portion of the power contributed by at least one wind turbine, or increasing the level of the power output by the grid power converter.
    Type: Grant

  • Reactive power management for wind power plant internal grid
    Patent number: 8121739
    Abstract: A wind power plant comprising a plurality of wind turbine converters coupled to a High Voltage Direct Current (HVDC) converter via an internal grid and a power plant controller. The power plant controller is configured to monitor a voltage of the internal grid, and allocate responsibility for generating reactive power to the HVDC converter and the wind turbine converters to maintain the voltage of the internal grid at a desired voltage.
