Abstract

As global energy demand increases and awareness of the environmental impacts of fossil fuels grows, the development of renewable energy sources such as Solar Power Plants (PLTS) becomes crucial. However, the intermittent nature of solar energy requires efficient energy storage systems. Batteries, specifically LithiumIon (Li-Ion) and Lead Acid types, become vital components in optimizing the utilization of solar energy. This research aims to design, build, and test the charging and discharging systems for Li-Ion and Lead Acid batteries using PLTS as the source, to gain a deep understanding of the characteristics of both types of batteries and to develop a system that can optimize their performance. The integration of power electronics technology and control systems will be implemented to enhance system efficiency. Based on testing and analysis, Li-Ion batteries show significant advantages over Lead Acid batteries for PLTS applications. Li-Ion has higher charging efficiency, greater depth of discharge, longer cycle life, faster charging times, and higher energy density. Li-Ion also performs more stably at high temperatures and, despite the higher initial cost, offers better economic value in the long term due to lower cost per cycle. This research is expected to make a significant contribution to the development of renewable energy storage technology, particularly in PLTS applications. The findings from this study can serve as a reference for practitioners and researchers in selecting and optimizing battery systems for future renewable energy applications.

Review

This research addresses a critically important area within renewable energy, focusing on the efficient storage of solar energy for Solar Power Plant (PLTS) applications. The authors undertake the design, construction, and testing of charging and discharging systems for two prominent battery technologies—Lithium-Ion (Li-Ion) and Lead-Acid—using PLTS as the energy source. This practical approach aims to gain a comprehensive understanding of each battery type's characteristics and to develop optimized systems for their performance within this context. The timely investigation into effective energy storage solutions underscores the paper's relevance in the face of increasing global energy demands and the intermittency of renewable sources. The study's findings provide a compelling comparative analysis, clearly demonstrating the significant advantages of Li-Ion batteries over Lead-Acid alternatives for PLTS applications. Specifically, Li-Ion batteries exhibited superior charging efficiency, greater depth of discharge, extended cycle life, faster charging capabilities, and higher energy density. Furthermore, their stable performance at elevated temperatures and better long-term economic value, despite a higher initial cost, are critical considerations highlighted by the research. The abstract notes the implementation of power electronics and control systems to enhance efficiency, suggesting a robust methodological foundation for these findings. These detailed comparisons offer valuable insights for system design and battery selection in renewable energy systems. Overall, this research promises to be a significant contribution to the field of renewable energy storage technology, particularly for PLTS applications. Its strength lies in its practical, hands-on approach (design, build, test) and its direct comparative analysis of two key battery types against multiple performance metrics. While the abstract effectively outlines the benefits of Li-Ion, further elucidation in the full paper regarding the *specifics* of the integrated power electronics and control system implementations, and detailed quantitative economic analysis beyond "cost per cycle," would undoubtedly enrich the study. Nevertheless, the findings offer a robust reference for practitioners and researchers in optimizing battery systems for future renewable energy endeavors, making this a highly relevant and impactful work.
