Hybrid Renewable and Storage Solutions for Efficient Public Building Energy Management
Abstract This paper presents a smart Energy Management System (EMS) for public buildings integrating photovoltaic (PV) generation and battery storage to enhance energy efficiency and reduce grid dependence. Using HOMER for system design and MATLAB/Simulink for control modelling, the EMS optimizes energy use, prioritizes solar and stored energy, and enables island or grid-connected operation as needed. Simulation results show improved energy efficiency, reliability, and cost savings while reducing carbon footprint. The proposed EMS offers a sustainable, scalable, and cost-effective solution for managing renewable energy variability in public infrastructure.
