Design and Optimization of a PVsyst-Based Hybrid Energy System for Grid Demand Reduction

Abstract

This research highlights the design of hybrid Photovoltaic-Battery Energy Storage System (PV-BESS) for sustainable energy solutions. The study focuses on designing reliable hybrid systems for Universiti Teknologi MARA (UiTM) Campus, aiming to reduce grid power demand. Using PVsyst software, it analyzes system design and performance. Through PV and BESS components optimization, the research study aims to determine the value of PV-BESS coupling within the framework, helping to make energy supply more sustainable and resilient. The research on optimizing photovoltaic (PV) and battery energy storage systems (BESS) in Malaysia’s commercial buildings demonstrated significant improvements in energy efficiency and reliability. By adjusting the PV panel tilt angle to 10 degrees with the Building Integrated Photovoltaic (BIPV) system, the design achieved consistent energy outputs and a performance ratio (PR) of 0.755, indicating efficient energy conversion. The system effectively utilized high global horizontal irradiation, with peak energy output in March. Integrating lithium-ion batteries addressed intermittency issues and enhanced sustainability. These findings provide a valuable benchmark for future PV-BESS studies in commercial buildings, offering insights into system optimization and performance.
