\(β^t=(1-μ_s^t).((μ_s^t(1+μ_s^t))/(σ_s^t)^2-1)(2)\)
\(α^t=(μ_s^t*β^t)/((1-μ_s^t))(3)\)
The decision to describe the random behavior of wind speeds is selected in a predetermined period of time Weibull PDF. The distribution of Weibull for wind speed \(V^t(m/s)\) in the time interval tm can be expressed as follows [24-25]
