Abstract: Incorporating renewable energy sources (RES), like wind and solar energy, is crucial for combating climate change and promoting sustainability. However, it introduces challenges to power quality (PQ) in distribution systems due to RES output variability, including voltage and frequency fluctuations and harmonics. Distributed flexible alternating current transmission system (DFACTS) devices, like unified power quality conditioner and distributed static compensator, effectively mitigate these challenges when appropriately controlled. Integrating energy storage systems (ESSs) like battery ESS with these devices and controlling them efficiently using traditional, AI-based, or adaptive control algorithms further enhances the mitigation performance of PQ in RES-connected grids. This review highlights PQ issues, categorisation, and mitigation strategies. It also highlights improving PQ in RES-integrated grids by enhancing DFACTS device performance through ESS combination and effective control. This review synthesises PQ enhancement strategies in RES-integrated grids from existing literature to support future research.

Keywords: control technique; DFACTS devices; energy storage system; power quality; renewable energy source.
