A novel estimation chart method based on capacity value calculated by using energy pattern factor to determine rated wind speed

Abstract

ABSTRACT The nominal rated wind speed is the most important parameter on the energy production of a wind turbine. However, when the literature studies are examined, there are no studies that have formulations directly related to nominal wind speed. Therefore, the aim of this study was to determine the nominal wind speeds that will obtain the maximum power from wind turbines. Nominal wind speeds were determined by analyzing the capacity values that were calculated directly by using the energy pattern factor. Thus, new and practical charts were created for the selection of the wind turbines with the most appropriate nominal wind speed to achieve maximum annual energy production. In the case study, it was observed that the selection of turbines with values below the appropriate nominal wind speeds decreases the annual energy production by 30.1%. This shows how the selection of turbines with the correct and appropriate nominal wind speeds in the areas where the wind energy power plants are planned to be installed is important in a general energy production.
