Resumo: | Wind energy is now one of the most promising energy sources of the world for being clean and abundant. The study of phenomena that are related to changes in atmospheric circulation, such as El Niño, are extremely important for its ability to affect wind generation. In order to explore the possible effect of such phenomena in the winds of the Northeast region of Brazil, a statistical analysis to quantify this effect through the model Generalized Autoregressive Score (GAS) is performed. This allows the modeling of time series for different probability distributions. Thus, the GAS is applied to the wind speed series from the Gamma distribution. The model results showed that El Niño has influence on the behavior of the wind, even though it is small in magnitude. |

O estudo de fenômenos que estão relacionados com alterações na circulação atmosférica, como o El Niño, são de extrema importância pela possibilidade de afetarem a geração eólica. A fim de explorar o possível efeito de tais fenômenos nos ventos da região Nordeste do Brasil, é realizada uma análise estatística para a quantificação desse efeito através do modelo Generalized Autoregressive Score (GAS). Este permite a modelagem de séries temporais para diferentes distribuições de probabilidade. Nesse estudo, o modelo GAS é aplicado às séries de velocidade do vento a partir da distribuição Gama. Os resultados do modelo mostraram que o El Niño possui influência no comportamento do vento, ainda que esta seja pequena em magnitude.Universidade Federal do Rio de Janeiro2017-02-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/783810.11137/2014_2_232_240Anuário do Instituto de Geociências; Vol 37, No 2 (2014); 232-240Anuário do Instituto de Geociências; Vol 37, No 2 (2014); 232-2401982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/7838/6319Copyright (c) 2014 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessLima, Carolina Nascimento NogueiraFernandes, Cristiano Augusto CoelhoFrança, Gutemberg BorgesMatos, Gilson Gonçalves de2017-02-15T17:28:22Zoai:www.revistas.ufrj.br:article/7838Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-02-15T17:28:22Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false |
