Abstract: A wind turbine includes a rotor comprising multiple blades mounted on a hub, MIMUs mounted on each blade for sensing parameter signals thereof, and a control system. The control system includes a wind speed calculation unit, a wind shear calculation unit, a pitch angle compensation command calculation unit, and a pitch control unit. The wind speed calculation unit is used for calculating wind speeds at the blades based at least on the sensed parameter signals. The wind shear calculation unit is used for calculating a characteristic shear exponent based at least on the calculated wind speeds. The pitch angle compensation command calculation unit is used for calculating pitch angle compensation commands of the blades based at least on the calculated characteristic shear exponent. The pitch control unit is used for adjusting the pitch angles of the blades based on the calculated pitch angle compensation commands.

Abstract: A wind turbine includes multiple blades, multiple Micro Inertial Measurement Units (MIMUs) for sensing parameter signals of the blades, and a control system. The control system includes a blade bending moment calculation unit, a blade bending moment error signal calculation unit, and a pitch angle compensation command calculation unit. The blade bending moment calculation unit is used for calculating blade bending moment values of the blades based at least on the sensed parameters. The blade bending moment error signal calculation unit is used for calculating blade bending moment error signals of the blades based on the calculated blade bending moment values of the blades and multiple blade bending moment commands. The pitch angle compensation command calculation unit is used for calculating pitch angle compensation commands of the blades based on the calculated blade bending moment error signals to adjust pitch angles of the blades respectively.

Abstract: Systems and methods for interfacing a renewable power source to a power grid are provided. A weather condition that may affect the power output of the renewable power source is identified. A potential impact of the identified weather condition on the renewable power source is determined. An output of the renewable power source that is supplied to the power grid is adjusted based at least in part on the determination.
