A scientometric analysis on DFIG-based wind energy conversion system research trends

Abstract This paper aims to provide a comprehensive summary of the current research on the global wind energy systems, in particular to Wind Energy Conversion Systems (WECS) with Doubly Fed Induction Generator (DFIG). The analysis is based on the Scopus database from the year 2001 to 2024 and uses multiple methodologies for analysis. During this period, 3,196 documented research papers related to DFIG-based WECS systems were identified. Only one paper was published in 2002, while 324 papers were published in 2018. Among the 22 countries contributing to this field, China, India, and Morocco led with 340, 317, and 131 articles, respectively. However, India demonstrated the best quality of research, with only 9% of its 317 papers classified as low quality, while 97.2% of these papers were considered high quality. Team efforts are prevalent, accounting for 79.32% of the work. The most frequently used journals for publication are the Journal of Renewable Energy with 83 articles, IEEE Transactions on Industry Applications with 52 articles, and the International Journal of Electrical Power and Energy Systems with 50 articles. English was the most commonly used language, reported in 97% of the papers. As a result, this research points out new directions and stimulates further investigations into wind energy research analysis.
