One of the ultimate goals of electric power systems is to “Keep the Light On”; however, ensuring an uninterrupted electricity supply is challenging for such a complex engineering network exposed to various threats. While for decades electric power systems have been designed to possess high levels of reliability to withstand typical threats, recent catastrophic power outages caused by extreme events have highlighted the importance and urgency of enhancing resilience of power system infrastructure. These extreme events consist of natural disasters (e.g., Hurricane Maria of 2017), man-made errors (e.g., Northeast blackout of 2003), and even ever-growing cyber incidents (e.g., Ukraine power grid cyberattack of 2015). At the same time, with the fast deployment of smart grids and increasing involvement of consumers in the power grid operation via information and communication technologies (ICT), cyber security and privacy issue is of a big concern. To achieve a more resilient and secure electric power system, various technical challenges need to be addressed spanning from planning to operation, and involving investment, preparation, prevention, response, mitigation, and recovery. Collaboration among multidisciplinary fields, including power engineering, operation research, computer science, data analytics, communications, and transportation, play an essential role to facilitate the target.
