Abstract

Enhancing the resiliency of the electric grid is a major challenge facing the electric regulatory bodies. Beyond the traditional approaches of improving the resiliency such as vegetation management, damage assessment and communication technology, the ever increasing share of Distributed Energy Resources (DER) can be used as a way of modernizing the grid. Strategically placed DER's can be effectively used to reduce the vulnerability of the interconnected system and also, reduce customer outage time. Although connecting the DERs into the traditional electric network can pose technical and regulatory challenges, they can be used efficiently to form smaller standalone grids or micro-grids during hours of emergency and extreme weather scenarios. In this study, we propose a modernized approach for optimally supplying loads using mixed integer linear programming (MILP) under multiple power outages by maximizing the loads assigned to each node. The scope of the problem is further expanded to form a MILP formulation for a three phase electric network taking into account the power balance and operational constraints. A numerical example with a real system is used to illustrate the effectiveness of both the formulations.
