In a groundbreaking study published in the journal *Energies*, researchers have systematically reviewed the integration of lithium-ion battery energy storage systems (LiBESSs) with photovoltaic (PV) systems to power auxiliary services in high-voltage power stations. Led by Sergio Pires Pimentel from the School of Electrical, Mechanical, and Computer Engineering at the Federal University of Goias (UFG) in Brazil, the research offers a comprehensive analysis of the feasibility, benefits, and challenges of this integration, potentially reshaping the future of energy supply in critical infrastructure.
The study, funded by the Brazilian National Electric Energy Agency (ANEEL), meticulously evaluated 803 scientific publications from 2013 to 2024, narrowing down to 107 eligible studies and ultimately selecting five as the most representative. The findings highlight that Li-ion BESSs combined with PV systems significantly enhance reliability, reduce dependence on conventional energy sources, and improve grid resilience, particularly in remote or constrained environments.
“Our analysis reveals that the integration of Li-ion BESSs with PV systems not only optimizes energy use but also provides a sustainable solution for powering auxiliary services in high-voltage power stations,” said Pimentel. “This integration can lead to substantial cost savings and environmental benefits, making it a viable option for the energy sector.”
The research underscores the importance of optimization models and multi-objective strategies for system sizing and operation. Practical case studies included in the review validate the effectiveness of these systems, demonstrating their potential to revolutionize energy management in high-voltage power stations.
However, the study also identifies challenges that need to be addressed, including cost considerations, regulatory frameworks, and performance variability. Pimentel emphasized the need for further experimental validations and pilot-scale implementations to accelerate the adoption of BESS-PV systems. “While the benefits are clear, we must also consider the long-term economic impacts and ensure that these systems are scalable and reliable for widespread use,” he added.
The findings of this systematic literature review could have significant commercial impacts for the energy sector. By reducing reliance on conventional energy sources and enhancing grid resilience, the integration of Li-ion BESSs with PV systems offers a sustainable and cost-effective solution for powering auxiliary services. This research not only provides a roadmap for future developments but also highlights the need for continued innovation and investment in energy storage technologies.
As the energy sector continues to evolve, the insights from this study will be instrumental in shaping policies and practices that promote the adoption of renewable energy solutions. The study’s rigorous methodology and comprehensive analysis make it a valuable resource for researchers, policymakers, and industry professionals alike.
