Resilience Metrics for Integrated Energy Systems: A Review

Extreme catastrophes like hurricanes, earthquakes and floods, as well as cyber and physical threats made by people, have become worse in recent years. These disasters have badly damaged electrical networks, resulting in prolonged outages and the destruction of substations, transmission systems and power generators. To achieve this goal, new approaches to grid management and operation planning are needed. There needs to be a clear definition of how to measure and evaluate resilience so that planning and operating options can be compared and improved. Several definitions, measurements and ways to judge the strength of a power system have been suggested, but none of them are standard. The integrated energy system (IES) is one possible solution to combat bad weather. This paper gives a thorough and critical analysis of existing definitions, measures and assessment methods, as well as suggestions to make clear definitions, measures and assessment methods for power system resilience that are widely used. The paper has also discussed the resilience metrics for IES.
