Abstract
The effects of yaw misalignment on the power curve of a 5-MW reference offshore wind turbine and on the expected annual energy production for wind conditions of offshore sites in UK and Brazil were studied. The goal was to determine a reduction factor to be used as input for new wind farm projects. To achieve the results, Monte Carlo simulations using the open source FAST (Fatigue, Aerodynamics, Structures and Turbulence) code for wind turbine simulation were performed and a stochastic approach was considered for the wind speed and yaw misalignment. Considering the effects of yaw misalignment, an effective power curve for the 5-MW reference offshore wind turbine was obtained. Moreover, the yaw misalignment generated an annual energy production decreasing factor between 3% and 5%.
