An Adaptive, Multivariate Partitioning Algorithm for Global Optimization of Nonconvex Programs
Harsha Nagarajan, Mowen Lu, Site Wang +2
In this work, we develop an adaptive, multivariate partitioning algorithm for solving mixed-integer nonlinear programs (MINLP) with multi-linear terms to global optimality. This it…
Evaluating Ising Processing Units with Integer Programming
Carleton Coffrin, Harsha Nagarajan, Russell Bent
The recent emergence of novel computational devices, such as adiabatic quantum computers, CMOS annealers, and optical parametric oscillators, present new opportunities for hybrid-o…
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…
Probabilistic - Failure-Identification for Power Systems
Kaarthik Sundar, Carleton Coffrin, Harsha Nagarajan +1
This paper considers a probabilistic generalization of the - failure-identification problem in power transmission networks, where the probability of failure of each component…
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 Topology Design for Disturbance Minimization in Power Grids
Deepjyoti Deka, Harsha Nagarajan, Scott Backhaus
The transient response of power grids to external disturbances influences their stable operation. This paper studies the effect of topology in linear time-invariant dynamics of dif…
Chance-Constrained Unit Commitment with N-1 Security and Wind Uncertainty
Kaarthik Sundar, Harsha Nagarajan, Line Roald +3
As renewable wind energy penetration rates continue to increase, one of the major challenges facing grid operators is the question of how to control transmission grids in a reliabl…
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…
