Investigation of PV-Battery System Integration with Sports Facility Building : Comparative Analysis of Energy Management Strategies

Sammanfattning

This study evaluates the cost-effectiveness of integrating a battery energy storage system (BESS) with a grid-connected photovoltaic (PV) system at Rocklunda sports facility in Sweden. Unlike other commercial or residential buildings, the Rocklunda sports facility is dedicated to sports and recreational activities, leading to higher electricity demand due to energy-intensive operations such as heating and cooling systems, lighting, ventilation, and ice rink maintenance. Therefore, this study focuses on integrating a BESS with an existing grid-connected PV system to evaluate the economic feasibility of three operational strategies; price arbitrage, peak shaving and self-consumption. The study begins with a qualitative literature review to establish theoretical frameworks and derive key equations for cost, revenue, and net present value (NPV) analysis. Subsequently, a quantitative methodology is applied, using MATLAB to simulate energy management strategies and Excel to evaluate economic performance. Then, a sensitivity analysis was conducted to evaluate how variation in PV generation, electricity price and battery capacity affect the economic feasibility of the system. Based on current battery and electricity market prices, the analysis reveals that price arbitrage is the only viable energy management strategy at the moment for the Rocklunda sports facility.
