OCO-S: Online Convex Optimization with Stateful Costs and Sparse Communication
Yiwei Liu, Luwei Yang, Shunbo Lei
We study \textsc{OCO-S}, an online convex optimization setting in which decisions drive a stable dynamical state, losses are incurred along the induced state trajectory, and fi…
Delay-Robust Secondary Frequency Control via Passive Interconnection and Randomized Block Updates
Yiwei Liu, Luwei Yang, Shunbo Lei
This paper studies secondary frequency control in transmission networks subject to communication delays at the cyber-physical interface and limited per-update computation at the co…
Successive Fixing for Large-Scale SCUC Using First-Order Methods
Jinxin Xiong, Yanting Huang, Yingxiao Wang +4
Security-Constrained Unit Commitment is a fundamental optimization problem in power systems operations. The primary computational bottleneck arises from the need to solve large-sca…
Relax-and-Cut for Temporal SCUC Decomposition
Jinxin Xiong, Linxin Yang, Yingxiao Wang +4
The Security-Constrained Unit Commitment (SCUC) problem presents formidable computational challenges due to its combinatorial complexity, large-scale network dimensions, and numero…
