Performance analysis of wind resource assessment programs in complex terrain

Abstract

In order to provide optimal sitting of wind turbines, a reliable estimate of the wind resource over a given area is required. This paper compared the performance of two models, WAsP and WindSim in predicting the power production of individual turbines. The prediction accuracy is determined as function of wind direction (terrain), turbine spacing and turbulence. Recommendations are made as to the reliability and suitability of these models for different situations.
