New Outer Approximation Algorithms for Nonsmooth Convex MINLP Problems
Zhou Wei, He-Yi Liu, Bo Zeng
This paper presents a novel outer approximation algorithm for nonsmooth mixed-integer nonlinear programming (MINLP) problems. The method proceeds by fixing the integer variables an…
Leveraging Electric School Buses for Disaster Recovery: Optimizing Routing and Energy Scheduling via Branch-and-Price
Sayed Hamid Hosseini Dolatabadi, Yuchen Dong, Tanveer Hossain Bhuiyan +3
Natural disasters threaten the resilience of power systems, causing widespread power outages that disrupt critical loads (e.g., hospitals) and endanger public safety. Compared to t…
On the Existence of Lagrange Multipliers in Distribution Network Reconfiguration Problems
Rong-Peng Liu, Yue Song, Xiaozhe Wang +1
Distribution network reconfiguration (DNR) is an effective approach for optimizing distribution network operation. However, the DNR problem is computationally challenging due to th…
Two-Stage Robust Optimal Operation of Distribution Networks Considering Renewable Energy and Demand Asymmetric Uncertainties
Zhisheng Xiong, Bo Zeng, Peter Palensky +1
This paper presents a confidence level-based distributionally information gap decision theory (CL-DIGDT) framework for the two-stage robust optimal operation of distribution networ…
