Develop and deliver a software tool called LPNORM for designing resilient distribution grids to support meeting the MYPP goal and DOE major outcome of a "10% reduction in the economic costs of power outages by 2025." This tool is a novel combination of existing and new capabilities. LPNORM will allow users to import distribution and communication models, specify extreme weather events, specify resiliency criteria, and verify design solution quality with trusted power flow solvers.
