It examines the definition and operation of the components of a photovoltaic system, characterizes harmonics, models the network, and assesses the impact of resonance on the harmonics generated by inverters used in photovoltaic systems, along with the degree of photovoltaic penetration in the grid. Based on the above, OpenDSS software is used to calculate harmonic flux in the electrical distribution system, and the current, power, and voltage data obtained are processed using a Microsoft tool to enable better visualization and analysis of the results. The study considers two photovoltaic penetration scenarios: 10% and 60%. In both cases, harmonic voltage and current are analyzed under low and high irradiance conditions, observing whether voltage and current values increase or decrease. Furthermore, the behavior of the effective voltage and current is evaluated. The results obtained indicate that the degree of photovoltaic injection influences the presence of current and voltage distortions in a non-standardized manner.Acesso AbertoRessonânciaHarmônicosSistema fotovoltaicosResonanceHarmonicsPhotovoltaic systemsCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::MATERIAIS ELETRICOSTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
