Abstract
Over the last few years, the criticality of energy infrastructures has faced numerous global challenges. These include natural, human, process-based, and undesired events. There are many attempts conducted by scholars, practitioners, research centers, and academic institutes to introduce various frameworks and approaches to assess and improve the system reliability, maintainability, and resilience of energy infrastructure. The main goal of this chapter is to provide an overview of system safety, reliability, maintainability, and resilience frameworks of energy infrastructures that have been published in the past decades. In addition, it is essential to determine and analyze the common aspects of energy-critical infrastructures, the present challenges, and possible opportunities for future research directions. In this sense, an in-depth investigation is conducted using statistical metadata analysis. This subject discusses frontier directions and development trends to reveal the research status. Finally, a bibliometric study is undertaken to ascertain the most productive and influential researchers, research centers, and hotspot fields.
