| Abstract | This study evaluates the feasibility of implementing photovoltaic (PV) and energy storage systems to achieve Nearly Zero Energy Buildings (nZEBs) status for a cluster of buildings at the Mae Moh Training Center, Thailand. Using the Generalized Reduced Gradient method, three scenarios were analyzed: full-area installation, individual building optimization, and group optimization with energy storage. The full-area installation proved inefficient with only 24% PV utilization. Individual building optimization offered the shortest payback period of 3.17 years and 42% electricity reduction. Group optimization with energy storage emerged as the most comprehensive solution, achieving 75% PV utilization and 50% grid electricity reduction with an 8.67-year payback period for the optimal configuration of a 136 kW PV system and 100 kWh storage system. This approach best aligns with nZEB principles, offering balanced energy management and operational flexibility. The study demonstrates the potential of integrated PV and storage systems in achieving nZEB status. |
