Intelligent Energy Management System for Microgrids using Reinforcement Learning

Abstract

This paper investigates the application of Quantum Machine Learning (QML) for optimizing energy storage systems in renewable energy microgrids. Using Quantum Boltzmann Machines (QBMs), we demonstrate significant computational speedup and enhanced storage capacity, leading to improved integration with renewable energy sources, higher energy efficiency, and greater stability in microgrid operations. Our study shows that the QML-based approach achieves a computational speedup of 63% compared to classical optimization methods, with a 16% increase in storage capacity, enabling more efficient energy management. The integration of renewable energy increased from 60% to 70%, leading to a reduction in carbon emissions of approximately 1,200 metric tons of CO2 annually. Additionally, energy efficiency improved to 92.7%, with voltage fluctuations reduced to ±3% compared to ±6% in classical approaches. Statistical analysis confirms the significance of these improvements, with t-statistics for computational speedup and energy efficiency of 7.23 and 4.56, respectively, with p-values less than 0.001 and 0.002. These findings suggest that QML can play a pivotal role in enhancing the sustainability and efficiency of renewable energy microgrids. The implications of this study extend to broader adoption of renewable energy sources and more effective energy storage solutions. Future research should focus on exploring different QML architectures, scalability, and real-world implementation in various microgrid configurations. This study paves the way for a more sustainable and efficient energy future through the advanced optimization of energy storage systems using quantum-based approaches.
