Introduction
• M. DAHBI used The Weibull density function to estimate the monthly power wind density and to determine the characteristics of monthly parameters of Weibull.
• A simulation model established to describe the characteristics of a particular wind turbine.
• The monthly power generated and the monthly operating hours by the wind turbine to be simulated.
• Simulation is performed using Matlab software environment.

Conti…• A.K.Azad analysed the wind speed data statistically using
Weibull distribution to find out wind energy conversion characteristics.
• Two important parameters like Weibull shape factor “k” and Weibull scale factor “c” have been calculated by four methods.
• The probability density function f(x), cumulative distribution function or Weibull function F(x) have been used to describe the best wind distribution between observed and theoretically calculated data.
• six statistical tools used to analyse the goodness of curve fittings and precisely rank the methods.

Weibull Density Function• The wind speed probability density function
• Wheref(v) = the probability of observing wind speed v. c = Weibull scale parameter k = dimensionless Weibull shape parameter.
• Weibull’s cumulative distribution function
