relationship between wind speed and wind power (S nchez 2006). It would seem wise to take this additional uncertainty into consideration when converting wind speed density forecasts to wind
Luzzatto-Fegiz & Caulfield (Reference Luzzatto-Fegiz and Caulfield 2018) developed a two-interface entrainment model for fully developed wind farms to analyse the power output density of wind farms. Their main
Particular attention should be paid to the air density since it significantly affects wind power generation and its accuracy. For example, the BARANI company, [14], concludes that weather
Accurate forecast results of medium and long-term wind power quantity can provide an important basis for power distribution plans, energy storage allocation plans and medium and long-term power generation plans

This study discusses the statistical properties of the wind power density function, particularly the mean power, standard deviation, skewness and kurtosis. The transformation method has been proposed for deriving a theoretical density function of wind power based on the wind speed pdf, such as the Gamma, Weibull and Inverse Gamma pdfs.
The wind power density model is useful for describing the distributions of wind energy at various wind speed values. As discussed above, wind power density is obtained by considering a suitable wind speed density function.
tory (NREL) of the USA. Mean wind power density has advantages over mean wind speed for comparing sites with different probability distribution skewness, because of the cubic nonlinear dependence of wind power on wind speed (see Fig. 11 in reference
The Wind Power Density (WPD) was determined by measuring wind speed at the analyzed location and considering the air density. Wind speed data collected from the meteorological station at a height of 10 m was extrapolated to the turbine hub height (80 m) using the power law to account for altitude variations in wind speed.
Based on the wind power equations discussed above, it can be concluded that the probability density function of the wind speed is very important in determining and evaluating wind energy potential. In fact, the Weibull pdf is among the most popular statistical distributions in the field of wind energy applications.
