Estudo dos procedimentos de análise e conexão de um sistema fotovoltaico na rede da CPFL

Abstract

The use of renewable energies, such as solar and wind energy, reduces carbon dioxide emissions into the atmosphere and enables the implementation of distributed microgeneration and minigeneration systems in homes, businesses and industries. However, it is only possible to integrate renewable energy sources with the electrical grid with the use of inverters, which are devices based on power electronics. Thus, this research presents an analysis of the implementation of a photovoltaic system in a commercial establishment, operating as distributed microgeneration. To carry out the analyses, the main agents that regulate the Brazilian electricity sector and the regulations that determine the minimum and mandatory requirements for connecting power inverters to the electrical distribution network were studied. To understand the operation of the photovoltaic generation system, a study was carried out about the equipment that make up the system, such as photovoltaic panels, inverter and bidirectional meter. In order to broaden the understanding of the procedures necessary for the operation of an on-grid system, a case study of the CPFL concessionaire was carried out, applying all the procedures described here, demonstrating a significant reduction in the amount paid for the energy bill of the consumer unit studied. Finally, a comparative study of an informative nature was generated between the CPFL, Light, CEMIG and Celesc distributors, on the documentation required at each stage of the process of connecting the system to the network, demonstrating that the operation of distributed micro and mini-generation is extremely important. importance for advancing the diversification of the national electricity matrix.
