Proposta de projeto e estimativa de regimes de operação de sistema fotovoltaico isolado para suprimento de cargas auxiliares em subestação de transmissão de energia elétrica. 2023. 60 f. Trabalho de Conclusão de Curso (Bacharelado em Engenharia Elétrica) - Escola de Engenharia Elétrica, Mecânica e de Computação, Universidade Federal de Goiás, Goiânia, 2023.http://repositorio.bc.ufg.br//handle/ri/24181This study is based on the dimensioning of an isolated photovoltaic system (SFV) for the supply of energy to feed loads of auxiliary services of a substation as the main scope to be achieved for the work. In order to reach the desired objective, as a methodology, a case study was carried out in a substation in the municipality of Trindade, in the State of Goiás. In order to guarantee the supply of energy to the auxiliary loads for a longer period of time, the design of an energy storage system based on lead-acid batteries. As a result, it was possible to observe that the implementation of the photovoltaic system guarantees an additional source of redundancy to feed the auxiliary loads, contributing to the continuous operation of the substation protection and operation system.porAcesso AbertoSistemas de armazenamento de energiaSistema fotovoltaico isoladoServiços AuxiliaresBateriasBESSEnergy storage systemsIsolated photovoltaic systemAuxiliary servicesEnergy storageBatteriesTCC
