Abstract
After establishing a design environmental condition (, S) for a wind turbine blade, and engineering a coefficient of lift and a corresponding optimum blade tip speed ratio (TSR) that maximizes annual energy production of the wind turbine when operating under the design environmental condition, determining a site-specific condition (, S, S) that changes a wind loading condition on the blade compared to the design environmental condition, and providing an add-on device () for the blade that maximizes annual energy production of the wind turbine under the site-specific condition by changing the coefficient of lift and optimum TSR of the blade. Site specific conditions may include reduced RPM () for noise curtailment and/or specific mean wind speeds (S, S). The add-on device may include a flap () and/or vortex generators ().
