        abstract = {Power quality is crucial in three-phase grid-connected solar systems to prevent interruptions and financial losses. The Point of Common Coupling (PCC) is an important location in interconnected energy systems. Power quality that reaches the electrical load connected at PCC is essential for equipment to function properly and prevent damage. For a PV inverter to operate efficiently with fewer harmonic distortions, a suitable grid synchronization strategy must be connected to a capable controller. The study employs fuzzy-based Direct Quadrature control for Pulse Width Modulation inverter control and a Direct Quadrature Phase Locked Loop (DQ-PLL) for grid synchronization. It intends to evaluate how well a fuzzy controller regulates the energy flow, preserves stability, and complies with grid standards in the setting of variable and intermittent renewable energy sources. 
Using MATLAB/Simulink software, this study critically analyzes power quality issues. Total Harmonic Distortion was used as the performance criterion. Using the IEEE 519-2014 standard for harmonic level, the total demand distortion for a fixed resistance-inductive load linked at the point of common coupling is confirmed to be acceptable. Consequently, the findings show that it may be applied successfully as one of the appropriate techniques for incorporating renewable energy into electrical grids, which is dependable with respect to shifts in the dynamics of the power grid.},
