Application of Photovoltaic Generation for Harmonic Distortion Mitigation in a Microgrid

Facing the rapid evolution that the electrical system has gone through, with the massive and growing insertion of inverter-based generators, the inclusion of renewable energy sources in the electrical system has allowed us to investigate the possible functionalities of these generators in different situations. In this scenario, the application of photovoltaic generators used as an active filter has been shown a promising solution for mitigating harmonics on the grid. Thus, emphasizing the multifunctionality of these generators. In this paper, we present an analysis of the application of a photovoltaic generator as an active filter for harmonic mitigation. We analysed the harmonic distortion caused by non-linear loads inserted in a medium voltage microgrid to evaluate the filter operation. The results presented illustrate the use of the inverter-based DG in the mitigation of harmonic distortion in the grid, showing the importance of the multifunctionality of DG in modern distribution networks.
