Abstract
This research presents a prototype intelligent energy system for the Industrial Engineering Building at Rajamangala University of Technology Srivijaya, integrating three core systems: Phase-specific Reactive Power Compensation, Smart Load Routing, and Grid-aware Load Allocation to enhance efficiency, reduce losses, and strengthen electrical system stability. Experimental results demonstrate that Static VAR Generator (SVG) installation in Phase B with high inductive loads improved Power Factor from 0.81 to 0.97 and reduced I²R losses by up to 27.8%. The Plug-and-Play Load Router system reduced inter-phase load imbalance by 28% through small-to-medium load switching with an average response time of 140ms. The Decision Tree model for grid-aware load allocation achieved 88% accuracy in Phase B voltage drop detection, improving voltage stability by 9.6% and enhancing overall Power Factor by an additional 4.3%. Each system is optimized for different load characteristics: SVG suits high unbalanced inductive loads, Load Router excels with continuously varying loads, and Grid-aware Allocation maintains voltage and frequency stability for critical applications. The integrated system architecture enables combined deployment for enhanced performance and sustainable renewable energy expansion capability.
