\(k^t=(σ^t/(μ_v^t))^(-1.086)(5)\)
\(c^t=(μ_v^t)/Γ(1+1⁄k^t)(6)\)
\(μ_v^t\) And\(σ_v^t\)  are the mean standard wind deflection deviations in the time segment t. To calculate the output power of wind and solar DGs, continuous PDFs are divided into periods for a specific time frame. In each of them, solar radiation and wind speed are at a certain level. Production of PV and WT array power is controlled by the probability of all possible states for that time.
The average hourly output power of a PV array is related to a specific time segment. \(t(P_pv^t)\)  Which can be calculated as follows: \cite{l2010}
