Projeto, implementação e análise do custo da energia de usina de microgeração com sobredimensionamento do arranjo fotovoltaico

Abstract

Photovoltaic systems have become popular worldwide due to their relatively low acquisition and installation cost, considering the quick financial return. In Brazil, the most popular systems due to the issues mentioned above are those connected to the grid, better known as on grid. Currently, Brazil has reached 10 GW of installed power of its own energy generation systems (Associação Brasileira de Geração Distribuída, 2022) and the tendency is for this power to increase more and more over the years to comply with environmental policies to reduce greenhouse gas emissions into the atmosphere by the year 2050 (UNFCCC, 2022). Therefore, this work aims to present a complete project of a microgeneration plant with a power of 75 kW inverter and 109 kWp in photovoltaic modules connected to the grid, considering the system sizing, project with the concessionaire, executive project, construction and plant commissioning, maintenance planning and system monitoring. Another important point will be the analysis via simulation software on the use of a 100 kW inverter, being classified as minigeneration, in the same plant, considering the aspect of generation and financial return.
