Abstract
To mitigate the use of fossil fuels and continue to attend to the demand for electricity, many countries are investing in wind power. As wind speed is a random variable, the wind speed variation over a period of time can be represented by probability density functions, with the Weibull distribution being the most used. This paper aims to estimate the Weibull distribution parameters by the Ant Colony Optimization Method, a heuristic method widely used in wind energy studies. The implementation was performed using the R language, and the results were compared by statistical tests with those obtained by deterministic methods usually used for this purpose. The statistical tests results, RMSE equal to 0.001692, MAE equal to 0.003701, R2 equal to 0.996033 and the Wind Power Deviation equal to 1.3248\%, showed that the proposed method is effective to estimate the Weibull distribution curve parameters for the analyzed region.
