Accelerating Level-Value Adjustment for the Polyak Stepsize
Anbang Liu, Mikhail A. Bragin, Xi Chen +1
The Polyak stepsize has been widely used in subgradient methods for non-smooth convex optimization. However, calculating the stepsize requires the optimal value, which is generally…
Data-Driven Two-Stage Distributionally Robust Dispatch of Multi-Energy Microgrid
Xunhang Sun, Xiaoyu Cao, Bo Zeng +3
This paper studies adaptive distributionally robust dispatch (DRD) of the multi-energy microgrid under supply and demand uncertainties. A Wasserstein ambiguity set is constructed t…
Robust Co-Optimization of Distribution Network Hardening and Mobile Resource Scheduling with Decision-Dependent Uncertainty
Donglai Ma, Xiaoyu Cao, Bo Zeng +4
This paper studies the robust co-planning of proactive network hardening and mobile hydrogen energy resources (MHERs) scheduling, which is to enhance the resilience of power distri…
Proactive Robust Hardening of Resilient Power Distribution Network: Decision-Dependent Uncertainty Modeling and Fast Solution Strategy
Donglai Ma, Xiaoyu Cao, Bo Zeng +4
To address the power system hardening problem, traditional approaches often adopt robust optimization (RO) that considers a fixed set of concerned contingencies, regardless of the…
