To systematically evaluate research trends, geographic distribution, technological frontiers, and methodological gaps in hybrid renewable energy systems across 11 Southeast Asian nations.
Conducted a PRISMA 2020 systematic review searching Scopus and Web of Science (2014–2025), yielding 103 verified studies following full-text screening.
Applied qualitative critical synthesis, association-strength keyword co-occurrence mapping, and Kleinberg burst detection alongside standard bibliometrics.
Publication output expanded at a 26.4% log-linear compound annual growth rate (2014–2024), with 58.3% published in 2021–2025, but 5 of 11 countries had zero single-nation studies.
Solar-dominant systems constituted 68.0% of the corpus, battery storage featured in 42.0%, and 58.3% of studies lacked comprehensive sensitivity analysis.
Kleinberg burst analysis identified green hydrogen as the strongest active research frontier, while diesel hybrid bursts have terminated and machine learning applications remain sparse.
