Local wake impact on flow conditions
around wind farms are known to affect significantly wind energy
production. We perform here simulations with the WRF model using the Fitch
scheme for a densely exploited complex terrain region in Galicia, in
northwest Spain, with high wind resource. A period of one year is simulated
at 333m horizontal resolution, with a daily
operational forecasting set-up. Power and wind predictions are obtained and
compared with real data provided by the management company. Results show that
WRF yields good wind power operational predictions for this kind of wind
farms, due to a good representation of the planetary boundary layer behavior
of the region and the good performance of the Fitch scheme under these
conditions. Significant wake effects are observed for several kilometers
downwind from the farm especially in the prevailing wind directions
(southwest-northeast). These results show that this method can provide
valuable information, for possible wind farm future locations. |
