Abstract
Resilience, as a concept, has been recently become a strategic objective for power grids. However, there are still some conceptual unclarities. Resilience is often mistakenly used as a synonym for reliability. A power system can be reliable but not resilient. This paper clarifies this misconception. It discusses resilience definitions, cycle, and states to better understand resilience aspects. It also discusses power grids' new vulnerabilities and sheds the light on both cyber-physical resilience and cyber contingency concepts. Finally, it reviews the strategies used to enhance grid resilience.
