Armazenamento de Energia Elétrica em Baterias como serviço: Estudo de caso no eletroposto da Universidade Federal de Lavras

Nowadays, the use of electric energy has undergone a drastic change aiming at greater sustainability and efficiency. Integrating clean and renewable devices and generator sources to support or supplant the existing ones is the new reality. In this work, the well-known storage battery system project with photovoltaic modules is proposed to improve the current electric vehicle charging station located at the Federal University of Lavras. The objective is to turn the system self-sustainable and thereby generating income will pay the maintenance and implementation values. For this, initial calculations were carried out in order to size the components. Then, using the HOMER PRO software were obtained the essential elements of the project. The software allows to measure the financial and technical values of the project year after year throughout the estimated useful life of the system. It was possible to elaborate a more efficient electrical architecture and budget of CAPEX and OPEX for the project. The results show that this project is viable, providing a financial return after 25 years of the estimated useful life, with a total return of the initial financial investment in approximately 1.6 years.
