Our team recently published an international journal paper titled Empirical Study of Decentralized Group-Based Battery Energy Management (DBEM) for PV-Battery Nanogrid Systems in Islanded Mode. This study introduces DBEM as an efficient and sustainable solution for managing heterogeneous battery groups.
Key Highlights #
-
Introduction of DBEM: The paper presents a Decentralized Group-based Battery Energy Management (DBEM) system aimed at optimizing battery management in nanogrids, addressing challenges related to varying battery capacities and states of charge.
-
Prototype Development: A DBEM prototype system was developed at Kasetsart University Sriracha Campus, Thailand, featuring three islanded nanogrids equipped with 3.25 kWp PV arrays and 1200 Ah, 48 V battery groups, including both lead-acid and lithium-ion batteries.
-
Empirical Study: Over four years, empirical studies were conducted to assess the efficiency and effectiveness of the DBEM system in maximizing battery efficiency and lifespan nder real-world conditions.
-
Real-time Management: The DBEM system organizes batteries with similar characteristics into groups managed by a centralized controller, optimizing the charging and discharging processes in real-time, which significantly improves energy efficiency.
-
Key Findings: The results demonstrate that the DBEM system not only enhances energy efficiency but also prolongs battery lifespan, showcasing its potential for improving the performance of photovoltaic-battery systems in islanded nanogrids.
