Power curve correction A ridge situation with a negative shear profile could be significantly improved with the correction procedure. No correction Correction 100(Experimental/CFD) 77 96 AEP (GWh/y) for a turbine on a ridge with and without power curve correction
Conclusion Calculation of the AEP involves many disciplines, describing complex physical phenomenon. Consequently, a simple calculation procedure can not be set up. Basic cases show that CFD is clearly more accurate than linear methods. Important issues • Grid resolution • Roughness description • Climatology description; frequency distribution vs. time-series • Power curve correction
