The modern power systems are moving towards the future smart grid where increasing penetration of 13 renewable energy sources (RES) and power electronics is expected. While enabling the realization of 14 low-carbon power systems, the high penetration of RES reduces the security margin and resilience of 15 power systems against extreme events and disturbances. Meanwhile, power systems suffer from 16 increased vulnerabilities and security risks due to the growing integration of information and 17 communication technologies (ICT) in this ongoing transformation. As the consequences of power 18 system interruptions can be disastrous, enhancing the security and resilience of power systems with 19 practical methods has become a critical topic for the power industry.
