Advancement in techniques towards power quality improvement in Microgrid system: A comprehensive review

Abstract

Power quality is one of the prime views of modern energy schemes. Renewable-energy-based microgrids offer an attractive solution for improving the power quality of remote or isolated areas while diminishing greenhouse gas discharges. However, incorporating renewable energy origins into the grid can introduce significant challenges, mainly power fluctuations, voltage instability, harmonics, and frequency deviation. Here, a literature-based study has been done on the power quality improvement in microgrid. This review paper analyses 30 literature review papers published between 2018 to 2022, focusing on power quality improvement in recoverable -energy-based Microgrids. It also analyses the different techniques, simulation environments, and controllers used in each research work. Moreover, the advantages and research gaps in the collected research articles are also analyzed. Ultimately, the research gaps identified are also mentioned to assist future researchers in developing a novel and efficient approach for power quality improvement in microgrid-based systems.
