As the demand for increased energy harvesting grows, wind turbine rotor diameters and blade lengths have been expanding. This, however, comes with rising manufacturing and transportation costs. Additionally, the non-recyclable nature of carbon fiber presents an environmental challenge. Consequently, there is a pressing need for innovative approaches in the design of large-scale wind turbine blades. The objective of this invention is to present a novel methodology for the design and fabrication of inflatable horizontal axis wind turbine blades. This approach incorporates critical geometrical and structural features, such as varying twist angles, trailing edges, and load-bearing structural components. The invention also outlines a robust, tested manufacturing process utilizing PVC-coated fabrics, resulting in blades that are significantly lighter and more energy-efficient. This proposed methodology is applicable to any wind turbine airfoil. For illustrative purposes, the NREL S822 airfoil is used as an example in the design and manufacturing of the inflatable blades

The invention provides a method for controlling noise of wind turbines in a windfarm. Measured weather data measured noise data are obtained (O_WND) from a plurality of sensor nodes arranged at different positions in relation to the windfarm. Further, weather conditions (O_W_WT) are obtained at least at one wind turbine, e.g. from sensors/predictors in the wind turbine. The noise and weather data from the sensor nodes and wind turbine(s) along with distances (D) between at least some of the wind turbines and at least some of the sensor nodes are used to train a learning algorithm. Further, the learning algorithm is used to predict noise (P_N) at a position of one of the sensor nodes based on measured or predicted weather conditions at the windfarm.

Further, changing mode of operation (C_M_O) of one or more wind turbines of the windfarm based on the predicted noise at the point of interest, especially if the predicted noise exceeds a noise limit for the point of interest P_I. The method allows compliance with noise limits e.g. by slightly re-orienting one or more wind turbines to reduce noise, if it is predicted that a noise limit is exceeded, and this only costs a slightly lower than optimal energy generation in a limited time period.

A system and method reduce vibrations in a blade mounted on a hub of a wind turbine rotor when the rotor is in a limited yaw capacity state with a defined allowable yaw sweep. An allowable yaw sweep is defined for the limited yaw capacity state. A sensor in communication with a controller monitors for vibrations in the blade with the rotor at an initial yaw position. Upon detection of vibrations, the controller determines a yaw sweep sector that is within and less than the allowable yaw sweep and issues a command to a yaw system to yaw the rotor in a continuous back and forth manner in the yaw sweep sector. The controller continues to monitor for vibrations in the blade during or after the continuous yawing of the rotor and stops the continuous yawing of the rotor when the blade vibrations reduce to below the threshold level.
