Abstract
The high cost of energy production, coupled with the advantages of wind power as renewable and widely available source of energy, has led several countries to establish incentives to
regulate and promote wind power generation. This work proposes the implementation and comparison of two time series analysis methods: Piecewise Aggregate Approximation (PAA) and a PAA plus quantile regression process. The aim is to estimate the minimum amount of extreme cut-in and cut-out events of the wind speed in the power generation process. Brazil has an enormous wind power potential. The diversification of its energy matrix is becoming a necessary challenge nowadays in the commitment of using renewable energy sources. The performance of the two PAA based proposals is tested for to the wind farms of the south and
northeast regions. These locations belong to Brazil’s regions of different geographic and wind characteristics. This endows to also check the proposals robustness under divergent scenarios. The results indicate that the PAA/QR method performed better than the PAA method because it identified a greater amount of extreme values.
