Power quality is a critical aspect of modern power systems, ensuring reliable and efficient electricity supply to consumers. Power quality issues such as voltage fluctuations, harmonic distortions, and frequency variations can lead to operational inefficiencies, equipment damage, and disruptions in the power supply. This research focuses on the development of a power quality situationing system for power systems using Fuzzy-PI controllers. The proposed system leverages Fuzzy-PI controllers to effectively assess and manage power quality conditions. Fuzzy logic provides a mechanism to model and control complex and uncertain systems, making it suitable for addressing the dynamic and non-linear nature of power quality issues. The Fuzzy- PI controllers combine the benefits of fuzzy logic with Proportional-Integral (PI) control to ensure precise and responsive control actions..
