In this way, the production of electric energy is encouraged by the use of renewable energies like wind and solar. However, while adding these renewable energy sources to the electrical system, various problems with power quality may arise. However, the majority of the techniques in the literature focus on a particular power quality problem caused by one of the sources. However, because so many diverse renewable energy sources are now being integrated into the distribution system, the problem with power quality is getting worse.Consequently, the topic of power quality is presented in this study. Renewable energy resource-based distributed generators are predominantly gaining a lot of importance due to the advancement in technology and environmental concerns due to the huge demand for power to the utility grid
