Development of energy resilience research landscape using bibliometric analysis

Energy resilience has recently gained interest in both scientific and policy domains since it helps energy infrastructure withstand environmental impact and contributes to sustainable socio-economic development. Various definitions of energy resilience make it difficult for researchers to identify relevant research topics, research trends, and relationships among topics that suggest areas for collaboration. This study uses bibliometric analysis to develop energy resilience research landscape containing aforementioned information. Search term: energy OR power W/2 resilien* was used to extract bibliometric information from Scopus database. Four Bibliometrix tools, namely Word Growth, Trend Topics, Co-occurrence Network, Co-citation Network were used to develop the research landscape. Most relevant research topics were power grid-related topics, power system resilience against climate change and disasters, and topics often discussed with energy resilience, e.g., reliability and energy efficiency. Trendy research topics were microgrid, power system resilience, reliability, renewable energy, and critical infrastructure. Research topics can be divided into four clusters, namely overarching themes, resilience during disruptions, resilience during normal operations, and technologies contributing to energy resilience, with connections of topics within and between respective clusters. Four distinct definitions of energy resilience were derived from the four clusters in the research landscape and integrated into a comprehensive definition. Research topics identified in the landscape and their relationships synchronize well with global trends and policies. The evidence-based research landscape can facilitate research prioritization, research collaboration, and translation of research into policy and practice.
