Increased energy demand due to rapid industrialization, environmental concerns with fossil fuel-based generation, decreasing fossil energy resources, overloading of the transmission grids and deteriorating technical performance are the motivations for the integration of small decentralized renewable generation units (DG) and the conversion of existing energy. Optimizing the technical advantages of a DG placement is a well-known challenge for Distribution System Operators (DNOs) for DGs based on fossil and renewable energy resources, but renewable DG systems have several challenges in the network quality characteristic of renewable DG systems, as electricity loads react more sensitively to PQ disturbances and the penetration of renewable energies as well as non-linear loads, it spreads in the power distribution in grids.) Technologies are becoming inevitable due to the ongoing reform in traditional distribution networks through the integration of renewable energies. This article contains a comprehensive analysis of the challenges of network quality in the network integration of renewable DG systems and the current state of research on corresponding mitigation techniques, theoretically emphasizes all the decisive challenges in network quality associated with the network integration of renewable energies, and, secondly, creates a MATLAB model of distribution line with STATCOM. Observing various fault and adding rectifier load on line with and without STATCOM we can conclude the benefit of STATCOM. The high penetration of renewable energies and techniques for reducing power quality are also demonstrated by the simulation of a grid-integrated PV-based DG system in MATLAB / Simulink. This article is believed to be very useful for academics and industry professionals to understand existing PQ challenges, PQI techniques, and future research guidelines for renewable energy technologies.
