Impact of blade structural and aerodynamic uncertainties on wind turbine loads

Offshore wind power has been in the spotlight among renewable energy sources. The current trends of increased ratings and longer blades come together with aim to reduce costs by design optimisation. standard approach deal uncertainties wind-turbine use characteristic values safety factors. This paper focusses on modelling effect structural aerodynamic blades. First, laminate properties are characterised propagated a blade model means Monte Carlo simulation. Wind tunnel measurement data then used define variability lift drag coefficients for both clean rough aerofoil behaviour, which is extrapolate behaviours throughout blade. A stochastic spatial interpolation parameter evolution degradation level. combined variance contribution these two uncertainty sources turbine loads finally defined aeroelastic research aims provide framework understand their effects behaviour.
