Calculation of Air Density for Wind Energy Systems Use

In recent years, wind farms are being located at mountainous high altitude locations in turkey. nevertheless, most important point to pay attention for those locations are that the air density is lower and this effects the production of wind turbines directly. if the feasibility calculations are not performed in detail on the subject, small effects of air density can create a big loss in long term operational wind farms. in this study, two known methods (i) international standards for calculations and (ii) widely used engineering method are applied on datasets from 126 weathers stations all around turkey and calculations are compared with each other. results show similarities on yearly averages but outlines up to 2% differences in different months of the year.
