A Three-Stage Procedure for Controlled Islanding to Prevent Wide-Area Blackouts

open access: yesEnergies, 2018
Controlled islanding has been proposed as a last resort action to stop blackouts from happening when all standard methods have failed. Successful controlled islanding has to deal with three important issues: when, and where to island, and the evaluation ...

Constrained spectral clustering based methodology for intentional controlled islanding of large-scale power systems

open access: yes, 2015
Intentional controlled islanding is an effective corrective approach to minimise the impact of cascading outages leading to large-area blackouts. This study proposes a novel methodology, based on `constrained spectral clustering', that is computationally
