This paper proposes a methodology for enhancing power systems resiliency byproactively splitting an interconnected grid into small self-sustaining islandsin preparation for extreme events. The idea is to posture the system so thatcascading outages can be bound within affected areas, preventing thepropagation of disturbances to the rest of the system. This mitigation strategywill prove especially useful when advance notification of a threat is availablebut its nature not well understood. In our method, islands are determined usinga constrained hierarchical spectral clustering technique. We further check theviability of the resultant islands using steady-state AC power flow. Theperformance of the approach is illustrated using a detailed PSS/E model of theheavily meshed transmission network operated by PJM Interconnection in theeastern USA. Representative cases from different seasons show that variationsin power flow patterns influence island configuration.
