Targeted Resilient Zoning for High Impact Events via Multi Circuit Polelines

Abstract

The increasing frequency and severity of High Impact and Low Probability events such as hurricanes and windstorms pose significant challenges to the resilience of electrical power distribution systems, particularly in regions of New England where there is a significant amount of overhead infrastructure in areas where vegetation is predominant. Traditional reliability-focused planning is insufficient to address the systemic vulnerabilities exposed by such extreme events. This paper presents a novel risk based framework for long term resilience planning of active overhead distribution systems, with a specific focus on mitigating the impacts of high wind and hurricane induced outages.
