Assessment Framework for Electric Power Systems Under Hypothetical Wind Storm Trajectories

The connectivity of alive portions of the power system network is of prime importance to begin the recovery efforts after the landfall and impact of a storm. In this paper, the modeling of pre-, during, and post-disaster electric power system infrastructure is presented. These models characterize the landfall and impact of a storm. Graph representation is utilized to establish the network properties. Models are used to propose an assessment framework to evaluate the impact of a storm on the overhead power lines in a region. The Puerto Rico electrical power system is taken as an example to present the modeling procedures. Results indicates that our framework effectively estimate the affected lines and circuits due to a wind storm impact. This framework can be used for system planning of future high-impact, low-probability (HILP) events.
