Uma análise dos requisitos técnicos mínimos para desempenho de usinas fotovoltaicas de acordo com os procedimentos de rede do ONS.

Abstract

This work aims to conduct a detailed analysis of the technical requirements requested by the National Electric System Operator (ONS). These requirements are essential for photovoltaic plants integrated into the electrical grid to operate in conjunction with the national electrical system without causing oscillations. The study presents the equipment available in the laboratory, which is used for performing certification tests according to INMETRO's Ordinance 140 for photovoltaic inverters. Furthermore, a comparison is made between the requirements requested by the ONS and those established by the National Institute of Metrology, Quality, and Technology (INMETRO) in Ordinance 140/2022. Finally, the necessary adjustments in laboratory procedures to effectively carry out these tests according to the required standards are identified and discussed.
