Evaluation of Wind Energy and Atmospheric Stability in Edincik

Meteorological conditions significantly influence wind energy production, necessitating careful consideration during the installation of wind turbines to optimize efficiency. It is crucial to evaluate the atmospheric stability or instability, as turbulence within the atmospheric boundary layer markedly affects wind energy generation. This research provides a comprehensive analysis of the impact of meteorological conditions on wind energy production. The results indicate that energy production varies extensively with weather conditions and turbulence levels. By incorporating atmospheric stability, turbulence dynamics, and aerodynamic principles into assessments, a more accurate prediction of energy production can be achieved. This enables improved design and operational strategies for wind farms. For this study, wind data from the European Centre for Medium-Range Weather Forecasts (ECMWFs) was used, along with observational data from a wind turbine located in the Edincik region. This dataset includes measurements at 100 m of wind speed, wind direction, and energy output. Turbulence was quantified using metrics such as turbulence kinetic energy (TKE), horizontal and vertical turbulence intensities, power law expression, and Reynolds decomposition methods. The analysis reveals that lower turbulence intensities and TKE generally correlate with higher energy output, although the rate of turbulence dissipation appears to have a negligible impact on energy production. Generally, lower TKE is associated with increased energy export. Daily variations in turbulence, wind speed, atmospheric stability, and terrain significantly influence energy output. Seasonal changes in turbulence intensity are also observed, primarily due to atmospheric instability and wind shear.
