Stochastic Spatio-Temporal Hurricane Impact Analysis for Power Grid Resilience Studies

This paper develops a spatio-temporal hurricane impact analysis (STHIA) tool to assist power industry stakeholders in quantifying hurricane damage to the power grid. The STHIA model generates stochastic hurricane scenarios based on historical hurricane data, and maps likely outage scenarios to inland distribution components using component-specific structural information expressed by fragility curves. The outage scenarios generated by the STHIA model enable its user to identify potential risks to the power grid in the hours or days leading up to an impending hurricane event. Further, the STHIA model can be used as a contingency planning tool in order to identify grid-hardening measures.
