Leveraging Predictions in Power System Voltage Control: An Adaptive Approach
Wenqi Cui, Yiheng Xie, Steven Low +2
High variability of solar PV and sudden changes in load (e.g., electric vehicles and storage) can lead to large voltage fluctuations in the distribution system. In recent years, a…
Flow-CDNet: A Novel Network for Detecting Both Slow and Fast Changes in Bitemporal Images
Haoxuan Li, Chenxu Wei, Haodong Wang +9
Change detection typically involves identifying regions with changes between bitemporal images taken at the same location. Besides significant changes, slow changes in bitemporal i…
Fast and Reliable Contingency Screening with Input-Convex Neural Networks
Nicolas Christianson, Wenqi Cui, Steven Low +2
Power system operators must ensure that dispatch decisions remain feasible in case of grid outages or contingencies to prevent cascading failures and ensure reliable operation. How…
Convex Restriction of Feasible Sets for AC Radial Networks
Ling Zhang, Daniel Tabas, Baosen Zhang
Many problems in power systems involve optimizing a certain objective function subject to power flow equations and engineering constraints. A long-standing challenge in solving the…
