JUMILLA CORRAL, Adán Alberto et al. Analysis of the behavior of current harmonic distortion in inverters interconnected to the electrical grid, through the use of experimental design methodology. Rev. cienc. tecnol. [online]. 2023, vol.6, n.1, e239.  Epub Aug 14, 2023. ISSN 2594-1925.  https://doi.org/10.37636/recit.v6n1e239.

In this research work, a study of the behavior of current harmonic distortion was carried out in a load node fed by the public electricity network and by inverters interconnected to the same node. The analysis was developed through an experimental design, using statistical tools such as analysis of variance and complete factorial arrangements, applied to experimental data obtained by configuring a test bench with a common coupling point with the load, where They integrate the powers of the network and renewable systems (photovoltaic), through electronic inverters. The results obtained show that the impact on current harmonic distortion in the load node depends mainly on the type of inverter used and the load connected to the node. In addition, the harmonic flows appear to a greater extent in the supplier's network compared to the harmonics present in the loads connected to the node under study.
