Statistical Analysis of Wind Speed Profile. A case study from Iasi region, Romania

Abstract

The increased integration of wind power into the electric power systems brings new challenges for effective planning and operation. The Weibull distribution is a widely used distribution, especially for modelling the random variable of wind speed. In the paper, the author presents a comparative analysis of some methods for estimating the Weibull parameters. These methods require historical wind speed data, collected over a certain time interval, to establish the parameters of the wind speed distribution for a particular location. Results for a real-world database, collected from the north-east area of Romania, are presented in a study case.
