        abstract = {This paper focuses on the design and implementation of a Unified Power Quality Conditioner (UPQC) integrated with a solar photovoltaic (PV) system to enhance power quality through an Artificial Neural Network (ANN) controller. The proposed ANN controller replaces the conventional Proportional-Integral (PI) controller to achieve superior Total Harmonic Distortion (THD) performance. The solar PV system employs the Perturb and Observe (P&O) technique for Maximum Power Point Tracking (MPPT), which ensures optimal energy extraction even under variable environmental conditions. The system uses p-q theory for the control strategy, enabling the mitigation of voltage and current issues, such as harmonics, sags, and swells. The entire configuration is developed and analyzed using MATLAB/Simulink, allowing for comprehensive modeling and performance evaluation. Simulation results indicate that the ANN-based controller enhances the system's ability to manage power quality disturbances more effectively compared to conventional methods. The proposed UPQC tied solar PV system serves as a robust solution for integrating renewable energy sources into the grid, addressing power quality challenges, and ensuring reliable energy supply in grid-connected applications. This study highlights the potential of ANN controllers in improving the efficiency and stability of renewable energy-based power quality conditioning systems.},
