Abstract
Wind resource assessment, especially for regions with complex terrain, is one of the most essential topics for wind energy development. In this paper, a novel method based on on-site measurement coupled to computational fluid dynamics (CFD) simulations is proposed to reproduce the spatial variability of wind speed distribution over the region with complex terrain. The on-site measurement data of wind speeds are adopted in the data fusion for wind speed distribution estimation and reproduction, combined with the simulation results of CFD. Next, a case study on wind resource assessment for a wind farm in complex terrain, located in Hebei Province, China was done. One year wind measurements with anemometers on three different sites were performed adopting the proposed approach. A cross-validation of the results of the proposed method against on-site wind speed measurement data indicates a good agreement. The results show that the approach proposed have reproduced a wind resource map with high resolution and the wind speed estimations for one spot within the wind farm are with a root-mean-square error of 0.399 m/s, which is qualified for wind farm planning in complex terrain.
