Abstract
Grid integration is the process of linking distributed energy resources, such as small-scale photovoltaic systems, to the electrical grid. Improving the power quality in the integrated grid of small-scale solar plants requires addressing many technological issues in order to create a secondary distribution network. Thus, this review provides a thorough synopsis of the current state of the art in power quality improvement methods for grid integration, with a focus on PI-Based Reactive Power Control Systems, Flicker Logistic Control Methods, Automated Filtering Mechanisms, Shunt Active Power Filter modules, Integrated Optimization-based AI Technique, and Grid Synchronization Techniques. To help readers better understand how each method contributes to better power quality, the review discusses the pros and cons of each. To further prove that different methods for improving power quality are successful, it offers a comparison study. The evaluation thoroughly assesses how each technique tackles issues like voltage fluctuations, harmonics, and flicker, ultimately leading to a more consistent and dependable power source. In addition to outlining potential avenues for future study and the difficulties inherent in applying different methods to improve power quality during grid integration of small-scale photovoltaic systems, this review offers some recommendations for how this area might be improved.
Keywords: Photovoltaic (PV) power plants, ultra-weak grids, adaptive reactive power control (ARPC), power transfer capability, voltage stability, short-circuit ratio (SCR), grid impedance estimation, sustainable energy systems
