EVALUATION OF WIND ENERGY POTENTIAL OF THE BLACK SEA COAST USING CFSR

The quality of the source data (sufficient spatial and temporal frequency) is decisive in the calculation of wind energy. In recent years, specialized data bases are increasingly used for regional assessments of wind potential and wind farm performance forecast. These databases provide the results of averaging the ground observation data, satellite data and mathematical modeling. In this connection, an important task is to verify such data and involvement reanalysis data in wind energy calculations. The work carries out verification of reanalysis NCEP CFSR on measurements of ground stations (Roshydromet network) and data of SODAR at altitudes up to300 m. A detailed comparison of the different wind characteristics that calculated on base of the reanalysis and specialized databases (NASA SSE, NASA POWER) is proposed. Calculation methods of wind speed and repeatability at a predetermined height based on CFSR are described. Region of research is the territory of the Black Sea coast of theNorth Caucasus, which is characterized by rather complex and diverse topography. Map of wind on the Black Sea coast of theCaucasus(height50 m), built using reanalysis data about average speeds allows the researchers to highlight the most productive areas for further detailed investigation. The proposed methodology for calculating wind speed and repeatability at a predetermined height, which based on reanalysis of high spatial resolution can be productively used to evaluate the wind energy potential.
