Abstract:Based on the review of resilience study, the research value to introduce resilience theory into energy system research is discussed. Then the resilience of energy system is refined and the conceptual framework of energy system resilience is constructed and explained. From the aspects of research object identification, disturbance factors, quantitative assessment methods for energy system resilience, and resilience improvement paths, etc., a research framework for energy system resilience is established. Moreover, the research direction and focus of energy system resilience are discussed. Finally, the possible problems and challenges in future research are proposed. From this article, it is found that the research of energy system resilience has theoretical value and practical significance. However, while the current research mainly focused on the exploration of conceptual framework and assessment indexes, the formation mechanism and dynamic evolution process of energy resilience, the function mechanism of disturbance factors to energy systems remain uncleared. Issues such as the verification and application of the resilience assessment models require in-depth research.
