In recent years, there has been a change in the way we produce and consume energy, with a significant increase in distributed generation, especially solar and wind. However, these sources are intermittent and do not guarantee constant availability. Given this, there is a need to consider the use of energy storage systems to increase the availability and flexibility of the electrical system. Using energy storage systems may help to balance energy supply and demand, reduce dispatch constraints, and improve the system reliability. Energy storage can also postpone investments in grid expansion. The present work aims to present an evaluation of the financial forecasts of the integration of a storage system together with a photovoltaic system in the distribution grid. For this purpose, we carried out a comprehensive review of the Brazilian energy scenario, including its various sources of energy generation, the constructive aspects of photovoltaic generation systems and the available energy storage technologies. Furthermore, rate modalities and the classification of consumers connected to the National Interconnected System (SIN) were examined. Finally, using the HOMER software, a detailed analysis of the economic perspectives was made, using load profile data from a consumer located in the city of Santa Cruz do Sul, in the state of Rio Grande do Sul, where the most financially viable combination was found using a battery energy storage system and a hybrid photovoltaic system connected to the grid.
