Relaxations of AC Maximal Load Delivery for Severe Contingency Analysis
Carleton Coffrin, Russell Bent, Byron Tasseff +2
This work considers the task of finding an AC-feasible operating point of a severely damaged transmission network while ensuring that a maximal amount of active power loads can be…
Structure- & Physics- Preserving Reductions of Power Grid Models
Colin Grudzien, Deepjyoti Deka, Michael Chertkov +1
The large size of multiscale, distribution and transmission, power grids hinder fast system-wide estimation and real-time control and optimization of operations. This paper studies…
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 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…
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…
