The most recent development in the realm of FACTS equipment and technology is the interline unified power quality conditioner. that improves voltage control at both the grid side and load side bus. When compared to its homologous counterpart, the traditional Unified power quality conditioner, the new FACTS device's effectiveness is evaluated. The research presents a soft computing technique, specifically a fuzzy logic-based controller, for the planned Interline unified power quality conditioner. The proposed control topology's application and usefulness are evaluated, and The proposed control architecture is implemented, tested, and simulated in a MATLAB/SIMULINK environment.
