Armazenamento de energia em clientes do grupo A com microgeração FV

Abstract

Given the high cost of energy tariffs for Group A clients during peak consumption hours, there was a recognized need for solutions that could meet consumption during these times more economically. Therefore, the storage of energy combined with photovoltaic microgeneration is a potential solution to consider. In the course of the work, various scenarios were explored, considering alternative solutions such as diesel to meet consumption more cost-effectively. To conduct a more comprehensive analysis, a study was conducted with two consumer units having significantly different peak consumption profiles. This aimed to determine whether the scenarios with potential solutions would be equally viable or not. Using consumption data from the consumer units, it was possible to dimension both photovoltaic solar systems and battery banks, along with diesel generators, allowing for a comparative analysis. Simulations were performed using software such as PVSyst, and financial analyses were conducted using Excel. In conclusion, it was observed that energy storage systems are not yet feasible for all consumption profiles. For consumer units with low energy consumption during peak hours, these systems proved to be viable and competitive with diesel generators for the same purpose. However, in cases of high consumption, energy storage is still not economically viable.
