Dimensionamento de um sistema fovotoltaico autônomo baseado nas informações de consumo e irradiância solar durante um ano

Abstract

Residential consumer units bring together the largest quantity of SFV and the largest installed power, with 570 thousand installed systems representing an installed power of 3,644 MW. With the new trend established by the regulatory framework, the need has arisen to enable the insertion of SFCR's into the electrical grid, which originally do not have batteries, however, with the taxation of energy injected into the grid through Law 14,300, together with future increases in electricity tariff, has been sparking interest in batteries with the SFCR. From this, the present work sought to demonstrate the particularities and particular criteria regarding the need to use an autonomous photovoltaic system, as an alternative to the consumption of electrical energy. The research was based on the demand behavior of a single-family consumer unit, from which it was possible to see the energy profile. It was possible to conclude that the technology can be used effectively when sized correctly, and that only the criterion of the largest month becomes the most suitable due to easy proof of electrical energy availability, presenting values higher than the unit's consumption in all The months of the year.
