Abstract
AbstractIn the wind energy sector, the yearly energy production is often calculated using a constant value of air density based on the location's annual average value. As a result, the correction necessary in assessing daily, monthly, or seasonal wind power density (WPD) owing to air density is typically neglected in current literature. Therefore, the present study assessed the WPD due to variations in air density. Indian offshore region is considered as a study area. Further, wind speed, air density and temperature data are taken from the latest ERA5 reanalysis. The findings show that the WPD is higher by 5% as determined by when the air density adjustment is taken into account. Seasonal results show that during summer, WPD has a maximum variation of about 7–8% and a minimum variation of about 2–5.5% during winter.KeywordsWind power densityStandard air densityReal air densityERA5India
