Power quality assessment of the interconnection of a microgrid to a local distribution system using real-time simulation. Dyna rev.fac.nac.minas [online]. 2020, vol.87, n.213, pp.28-33.

This article evaluates the impact of the interconnection of a microgrid to a local distribution system on power quality. A real-time simulation was used to carry out the study, applying national and international power quality standards, IEEE 1547 of 2018, IEEE 519 of 2014 and NTC 5001 of 2008. Phenomena of voltage harmonics, current harmonics, flicker and DC injection were evaluated on a microgrid case study. The results show that the interconnection of the microgrid produces a high impact on the current harmonics and the DC injection of the local distribution system, while the flicker phenomena and voltage harmonics have a lower impact.

Keywords : Power Quality (PQ); microgrid; real-time simulation; harmonics; flicker; DC injection.
