Desafios e Soluções na Manutenção de Sistemas de Armazenamento de Energia em Baterias: Um Estudo de Caso na ISA CTEEP

Abstract

The integration of energy storage into the electrical grid is essential for dealing with the intermittent nature of renewable sources and increasing system reliability. However, Battery Energy Storage Systems face critical challenges related to safety and reliability during their operation and maintenance. Thus, this study investigates failure analyses and preventive maintenance strategies for BESSs, based on global incidents and a case study at ISA CTEEP, one of the largest electricity transmission groups in Latin America. The importance of internal battery temperature management and early detection of thermal events is emphasized, as well as the ongoing need to enhance safety and regulations. Additionally, the use of internal impedance monitoring is proposed as a promising technique for predictive maintenance of these systems. Finally, this work also addresses challenges such as data scarcity and lack of standardization in accident reporting, highlighting the need for comprehensive guidelines to promote the safety and reliability of these systems in the electrical infrastructure. The research aims to contribute to advancing understanding and practices related to these systems, driving their sustainable and secure adoption.
