  • System, method, and computer program product for utilizing a wind park as a variable power system stabilizer
    Patent number: 8618694
    Abstract: System, method, and computer program product for dampening oscillations of the electrical power on a power grid. The system includes a wind park with multiple wind turbines. Each wind turbine includes a rotor, a generator operatively coupled with the rotor for generating electrical power, and an inverter coupling the generator with the power grid to output the electrical power to the power grid. A controller is configured to generate a first control signal to cause the inverter of the first wind turbine to modulate the electrical power output by the first wind turbine for dampening oscillations of one frequency in electrical power on the power grid and to generate a second control signal to cause the inverter of the second wind turbine to modulate the electrical power output by the second wind turbine for dampening oscillations of a different frequency in the electrical power on the power grid.
