Optimal Layered Defense For Site Protection
Tsvetan Asamov, Emre Yamangil, Endre Boros +2
We present a model for layered security with applications to the protection of sites such as stadiums or large gathering places. We formulate the problem as one of maximizing the c…
Tools for improving resilience of electric distribution systems with networked microgrids
Arthur Barnes, Harsha Nagarajan, Emre Yamangil +2
In the electrical grid, the distribution system is themost vulnerable to severe weather events. Well-placed and coordinatedupgrades, such as the combination of microgrids, systemha…
Resilient Transmission Grid Design: AC Relaxation vs. DC approximation
Harsha Nagarajan, Russell Bent, Pascal Van Hentenryck +2
As illustrated in recent years (Superstorm Sandy, the Northeast Ice Storm of 1998, etc.), extreme weather events pose an enormous threat to the electric power transmission systems…
Optimal Transmission Line Switching under Geomagnetic Disturbances
Mowen Lu, Harsha Nagarajan, Emre Yamangil +3
In recent years, there have been increasing concerns about how geomagnetic disturbances (GMDs) impact electrical power systems. Geomagnetically-induced currents (GICs) can saturate…
Polyhedral approximation in mixed-integer convex optimization
Miles Lubin, Emre Yamangil, Russell Bent +1
Generalizing both mixed-integer linear optimization and convex optimization, mixed-integer convex optimization possesses broad modeling power but has seen relatively few advances i…
Tightening McCormick Relaxations for Nonlinear Programs via Dynamic Multivariate Partitioning
Harsha Nagarajan, Mowen Lu, Emre Yamangil +1
In this work, we propose a two-stage approach to strengthen piecewise McCormick relaxations for mixed-integer nonlinear programs (MINLP) with multi-linear terms. In the first stage…
Extended Formulations in Mixed-integer Convex Programming
Miles Lubin, Emre Yamangil, Russell Bent +1
We present a unifying framework for generating extended formulations for the polyhedral outer approximations used in algorithms for mixed-integer convex programming (MICP). Extende…
Designing Resilient Electrical Distribution Grids
Emre Yamangil, Russell Bent, Scott Backhaus
Modern society is critically dependent on the services provided by engineered infrastructure networks. When natural disasters (e.g. Hurricane Sandy) occur, the ability of these net…
