Summary:Power systems have been impacted by wildfires in many ways, forcing several utilities to rely on Public Safety Power Shutoff (PSPS) programs to mitigate wildfire risks. A resilient and cost-effective power system expansion planning solution in regions with increased wildfire risk may be achieved by placing new transmission lines while checking their availability given the increasing number of PSPS events. This paper proposes an optimization approach for the expansion planning of a power system under wildfire risk with a compliance check on power flows and system operation limits. The resulting model is a mixed-integer linear programming (MILP) optimization problem. The algorithm and model are assessed on a modified version of the Garver's system, and simulation experiments are performed to validate the effectiveness of the proposed formulation using different High Fire-Threat District (HFTD) Tier Zones.
