Análise da viabilidade econômica da substituição de um sistema de geração a diesel por um sistema de armazenamento de energia via baterias em uma microrrede

Abstract

As a consequence of the restructuring that electrical systems have undergone over the years, the use of microgrids has been boosted, along with the development of applied technologies. Energy storage systems using batteries have become allies capable of boosting this implementation, bringing several benefits to the systems in which they are inserted, such as possibilities of energy management, decoupling between generation and consumption through the displacement of load peaks and ease of integration with distributed generation systems. The present work aims to realize an economic analysis of the replacement of non-renewable energy sources in a isolated microgrid by an energy storage system with batteries. The microgrid in question is composed of wind and solar photovoltaic energy sources, however, due to the intermittency of such generating sources it is necessary to provide a third energy source to supply the demand in adverse conditions to generation. The simulation using the software HOMER Pro, where the cases were analyzed using Diesel generation and energy storage by batteries, the economic unfeasibility of carrying out the replacement for the parameters defined on this occasion was proven.
