Avaliação dos leilões de energia para sistemas isolados brasileiroso caso de Boa Vista (RR)

Abstract

This dissertation aims to evaluate the energy auctions for Brazilian isolated systems, for that, the city of Boa Vista, in Roraima state, was used as a case study. Firstly, this paper examines the resources which can be used in Boa Vista for energy generation, as well as the special requirements that the software must have in order to present reliable results. Among the programs, HOMER was the one with the best results for isolated systems. Second, HOMER and the energy resources available in Boa Vista were used to identify the best configuration of the power plants, in order to reduce the cost of energy and to decrease the greenhouse gas emissions. Finally, the results were compared with the Boa Vista energy auction of 2019, after analysis, the study concluded that the auction achieved the goal to procure energy from different sources, but it did not minimize the emissions. Regarding the energy cost, at the beginning the auction was responsible to reduce the cost of energy, however, in a scenario of high inflation rate, the cost rises and it could even exceed the cost of generation if it had not been carried out.
