Abstract

This work has as main objective to identify and to evaluate the contribution of harmonic injection and power distortion of two residential Consumers (C1 and C2). It was considered that Consumers are inserted in a microgrid represented by a system based on a modified 13-bar IEEE model. Currently, the injection of a Consumer's harmonics cannot be accurately measured, leading to penalizing other Consumers. Therefore, this issue is extremely important, since more non-linear loads and sources are inserted in the system. The amount of harmonics injected into the system and the Consumer's distortion power are calculated individually according to the IEEE 1459-2010 standard. The harmonic distortion index proposed by Anu and Fernandez (2020) is extrapolated and used to determine the contribution of harmonic injection by PV generation systems. Simulations using MATLAB/SimulinkTM validated the methodology adopted, regarding the determination of the responsibility of each Consumer over the harmonics injected into the network.
