Pumps as Turbines (PATs) coupled with Self-Excited Induction Generators (SEIGs) as an alternative energy generation method have been the subject of significant research in recent years. This paper presents a bibliometric analysis of the evolution of PAT-SEIG technology as an alternative energy generation source. An analysis of a comprehensive dataset of peer-reviewed journal articles, conference proceedings, and patents related to PAT-SEIG systems, using advanced bibliometric techniques and PRISMA to identify key research themes, influential authors, the growth of the field and patterns of collaboration, and changes in research focus over time. Over a publication period of 32 years, a total of 949 documents were reviewed using the PRISMA checklist, resulting in the selection of 77 documents for analysis. The findings indicate an increasing interest in PAT-SEIG technology, with an impressive annual growth rate of 9.45%. However, gaps have been identified which provide areas for further studies. These include the PAT prediction methods, voltage and frequency fluctuations in SEIG, and the overall efficiency of the PAT-SEIG system. The study provides insights into the current state of research and highlights areas that require further investigation as a way of contributing to the advancement of the technology.
