Caracterização de potencial eólico: estudo de caso para Maracanaú (CE), Petrolina (PE) e Parnaíba (PI)

Abstract

In recent years wind energy use is becoming competitive worldwide, making its participation more and more significant in electric power systems. The present paper shows a statistical analysis to characterize the wind potential of Maracanaú – CE, Petrolina - PE and Parnaíba -PI, in the northeastern of Brazil. Statistical analysis allows understanding of the future behavior of the stochastic process associated with the wind speed, aiming to estimate the electricity generation and the capacity factor of wind turbines, wind potential assessment of regions of interest and the impacts associated with operation of electrical systems. This statistical analysis of series of wind speed is performed to detect seasonality patterns and behaviors that may assist in the description of the stochastic process. Average standards with top wind speeds occurred in Parnaíba (10 and 11m / s - best month of the year) followed by Petrolina (8 and 9 m/ s - best month of the year). The regularity of the wind speed makes these regions favorable for the use of wind power
