Análise da demanda e consumo de energia elétrica, utilizando séries temporais, no Campus Santa Mônica da Universidade Federal de Uberlândia, MG

Abstract

Society has witnessed an intense technological breakthrough since the Industrial Revolution, which has become more pronounced in the late 1990s and early 2000s and has remained at high levels. This technological advance has accentuated the dependence and demanded, more and more, electric power generation. The paper stresses the importance of the role of higher education institutions (HEIs) as trainers of environmentally conscious citizens for the rational use of natural resources and especially for electric energy. The analysis of the behavior of the use of electric energy, at the Federal University of Uberlândia (UFU) Santa Mônica campus, was carried out based on the records of demand and consumption, considering the classification of installation class A, blue seasonal hour rate. In this work, the data of the historical series for peak hour demand (HP), off-peak hours (HFP), peak hour consumption (HP) and off-peak hour consumption (HFP) were used in the period from January 2004 to December 2017 and also the series of difference between contracted demand and measured in HP and HFP, this period from January 2008 to December 2017. The analysis was based on the time series methodology, in an attempt to identify the best model for understanding of the data behavior. Energy efficiency, linked to the reduction of consumption, becomes relevant under two aspects: i) associated with the conservation of environmental resources and; (ii) linked to management issues, such as improving the quality of expenditures in reducing costs and waste. It is expected that the statistical analyzes, the identification of the models and the notes focused on the energy efficiency regulations, can help the UFU managers in the decision making regarding the contracting and management of electric energy.
