Metodologia de dimensionamento de SFCR para microgeração : um estudo de caso em Várzea Grande-MT

Abstract

The current commitment made by governments around the world to reduce carbon dioxide emissions has contributed to a steep increase in the cost of electricity. In order to contribute to cost reduction, meet environmental requirements, and improve the efficiency of electricity supply, gridconnected photovoltaic systems (SFCRs) have been adopted worldwide. In this scenario, there are still challenges in accurately assessing the energy contribution of SFCRs to determine their technical feasibility in urban areas. Therefore, having mathematical and computational tools that can predict the energy contributions of SFCRs with simplicity and accuracy is of interest to ensure a return on investment for new SFCR units. This work proposes an approach for the sizing and energy contribution assessment of SFCRs through a methodology and computational simulation. A real case study is presented for a 27 kWp SFCR installed in a condominium in the Midwest region of Brazil. The results demonstrate the advantages of sizing SFCRs using an organized methodology and having software for simulation, optimization, and validation of SFCRs, allowing for evaluation of different scenarios, improved system performance, reliability, and assessment of variables that may cause future issues. Additionally, a properly sized SFCR reduces acquisition costs and can delay maintenance and/or component replacement.
