Performance analysis and optimization in renewable energy systems: a bibliometric review

Abstract

This study aims to conduct a bibliometric review of the performance analysis and optimization of renewable energy systems over the past 24 years. Using the Scopus database and the Biblioshiny (Bibliometrix R package), suitable keywords were combined for the articles published between 2000 and 2024, and 138 research papers were analyzed using the PRISMA framework. Of the selected articles, 72% focused on reliability and availability, and 58% focused on optimization techniques. On various aspects analysis was conducted such as annual scientific production, total citations per year, documents and authors citation, highlighted the relevant sources and authors, common key terms, etc. The growing focus on reliability and availability is highlighted in this analysis, indicating advancements in research and ever-more targeted research objectives. All these results help researchers in the future by giving them directions to explore more options to develop more efficient and reliable renewable energy solutions.

Article Highlights

This study highlights the top nations that are contributing to the studies on the reliability and optimization of renewable energy systems. India was found to be the largest contributor, with 100 articles published, followed by China (86 articles) and Iran (35 articles). This reflects India’s rising focus on sustainable energy technology and on upgrading the productivity of renewable energy systems. The study suggests that the global collaboration of countries like India, China, and Iran strengthens the progress in renewable energy studies. Therefore, this trend shows that international partnership is very important as it enhances renewable energy technologies around the world.

The term ‘optimization’ is the most frequently used term, having appeared 51 times. It shows the importance of this term in the research on renewable energy systems. The study identified that scientific publications have increased over time. The highest number of papers were published in 2023, and the lowest number of papers were published between 2000 and 2004. These results show the increasing interest in solving problems related to the performance, reliability, and availability of renewable energy systems. The results also proved that the improvement in technologies and methodologies gives a clear path for the researchers to focus on targeted objectives for their future studies in this domain.

Journals like Energy Conversion and Management play a significant role in publishing papers (7 articles) in this related area. The study also assessed the impact of top authors, institutions, and international collaborations and gave a clear outline of the research environment. Therefore, this analysis of top journals and thorough studies can help researchers and professionals to collect some information for their studies. This shows the important role of journals in sharing knowledge and methodologies for improving renewable energy systems.
