Abstract

Microgrids are essential for transforming the global electrical system towards decentralization and modernization, integrating diverse technologies such as renewable energy resources and energy storage systems. Effective management of distributed energy resources is the key to achieving the benefits of microgrids. Consequently, heuristic rules have emerged as a common approach to improve microgrid operation due to their efficiency and real-time decision-making capabilities. This paper proposes an enhancement to an existing heuristic algorithm for operating the battery energy storage system (BESS) in microgrids. The improved algorithm aims to provide better control of voltage magnitude, thus maintaining adequate voltage levels and improving the efficiency of the microgrid. Experimental studies in a real laboratory microgrid, located at the Universidade Estadual de Campinas (UNICAMP), validate the effectiveness of the enhanced proposed algorithm, demonstrating reduced voltage magnitude variations and voltage regulation compared to the original algorithm. The improved algorithm was also tested under different scenarios to evaluate its performance under varying conditions, further demonstrating its robustness and adaptability. (AU)
