Power grids are often run near the operational limits because of increasing electricity demand, where even small disturbances could possibly trigger major blackouts. The attacks are the potential threats to trigger large-scale cascading failures in the power grid. In particular, the attacks mean to make substations/transmission lines lose functionality by either physical sabotages or cyber attacks...
Investigation of the cascading failure is of great importance to understanding wide-scale power outages in electrical grids. In the current literature, researchers mainly evaluate the severity of a cascading failure process based on assessing its final damage, e.g., blackout size, to the grid. Generally speaking, the larger the final damage value is, the more severe the cascading process is. However,...
