Statistical Analysis of Villonaco Wind Farm Annual Energy Production

The Villonaco Wind Farm is located between coordinates 693030 E 9558392 N and 693526 E 9556476 N in the province of Loja in southern Ecuador. It is the first wind farm in continental Ecuador, with a capacity of 16.5 MW and a location of roughly 2720 m above sea level in rugged terrain, which is especially relevant compared to others wind farms in the global context. This paper presents a statistical analysis of the Annual Energy Production of the Villonaco Wind Farm in the period from 2014 to 2018. In this analysis, actual wind speed and active power values were used, outliers and missing data were identified, and a new methodology was used to complete the missing data. With the complete dataset, an analysis of variance was performed to compare the means of the annual energy production. The results obtained in this study show an error of ±4% compared to the information available on the website of the Agency for Regulation and Control of Energy and Non-Renewable Natural Resources of Ecuador.
