"This document is the final report on the project entitled 'Homeland Security Research and Technology Proposal (Optimizing Electric Grid Design Under Asymmetric Threat),' sponsored in part by the U.S. Department of Homeland Security, Office of Domestic Preparedness. This research has developed new optimization models and algorithms, embedded in a graphical user interface with supporting database, to assess the vulnerability of electric power grids to physical attacks by terrorists, and to identify measures to reduce disruptions caused by such attacks. Such measures might include improving security of key infrastructure elements and adding redundant grid capacity. This report consolidates our previous findings and presents our prototypic tool VEGA (Vulnerability of Electric Power Grids Analyzer). We demonstrate VEGA on two U.S. power grids, ERCOT (Electric Reliability Council of Texas) and WECC (Western Electricity Coordinated Council). We also show that there exists sensitive information available from public sources that could be used to plan physical attacks on the power grid."
