Suprimento sustentável de energia de curto, médio e longo prazos para a ilha de Fernando de Noronha utilizando Portfólio de Geração Renovável

Abstract

The objective of this work is to analyze, through a Case Study (CS), alternatives for the sustainable supply of electricity in the short, medium and long term for the island of Fernando de Noronha (isolated system), based on the proposal of a New Renewable Generation Portfolio (NPGR) and the elimination of the current dependence on power generation with diesel oil. To this end, it is proposed to use variable renewable generation as a priority primary source and the use of thermoelectric generation with biofuel as a firm secondary source (energy that can be produced by a given power generation source, without the risk of not meeting contracted amounts of energy), with power available to meet the energy demand. The association of wind, solar photovoltaic and storage generation in the archipelago was considered to allow the maximum possible participation in the composition of renewable primary sources to meet the daily energy demand and the complementarity of a renewable thermal generation base with the use of biofuel in Fernando de Noronha. In this sense, this Final Course Work (TCC) will use as the main indicators of technical-economic feasibility and sustainability, resulting from analyses and simulations, the Levelized Cost of Energy (LCOE) and the volume of Carbon Dioxide (CO2) emissions, among other indicators and concepts. In an innovative way from a methodological point of view, the individualization of each generating unit (“Segmentation by Generating Units”) was used in the analyses and simulations, for each type of source that makes up the portfolio, seeking to improve the representativeness and assertiveness of the results in the proposal of the so-called New Renewable Generation Portfolio (NPGR) for Fernando de Noronha. The “Segmentation by Generating Units” model associated with the use of a simulation application (HOMER PRO) allowed a more precise assessment to meet the “Flexibility” dimension of the electrical system, in addition to meeting the supply (“or products”) criteria “Energy” and “Power” in the formation of the NPGR for Fernando de Noronha.
