Power systems are prone to cascading outages leading to large-area blackouts with significant social and economic consequences. Intentional controlled islanding (i.e. the separation of the system into sustainable islands) is an effective strategy to mitigate these catastrophic events. To ensure a correct separation, nonetheless, it is crucial to de...

Power systems are prone to cascading outages leading to large-area blackouts, and intentional controlled islanding (ICI) can mitigate these catastrophic events by splitting the system into sustainable islands. ICI schemes are used as the last resort to prevent cascading events; thus, it is critical to evaluate the corresponding system risks to ensu...

The most likely cause of a provincial and/or regional blackout1 is sometimes a foreseen extreme incident, such as a severe snowfall, and may result in a cascading disconnection of the provincial supply area from the national interconnected power system. On 8 August 2012, the entire Republic of South Africa experienced a severe cold front, and the E...
