Approximating the Gomory Mixed-Integer Cut Closure Using Historical Data
Berkay Becu, Santanu S. Dey, Feng Qiu +1
Many operations related optimization problems involve repeatedly solving similar mixed integer linear programming (MILP) instances with the same constraint matrix but differing obj…
An Analysis of Market-to-Market Coordination
Weihang Ren, Alinson S. Xavier, Fengyu Wang +2
The growing usage of renewable energy resources has introduced significant uncertainties in energy generation, enlarging challenges for Regional Transmission Operators (RTOs) in ma…
Market Implications of Alternative Operating Reserve Modeling in Wholesale Electricity Markets
Hamid Davoudi, Fengyu Wang, Yonghong Chen +3
Pricing and settlement mechanisms are crucial for efficient re-source allocation, investment incentives, market competition, and regulatory oversight. In the United States, Regiona…
Assessing Electricity Service Unfairness with Transfer Counterfactual Learning
Song Wei, Xiangrui Kong, Alinson Santos Xavier +3
Energy justice is a growing area of interest in interdisciplinary energy research. However, identifying systematic biases in the energy sector remains challenging due to confoundin…
Compressing Branch-and-Bound Trees
Gonzalo Muñoz, Joseph Paat, Álinson S. Xavier
A branch-and-bound (BB) tree certifies a dual bound on the value of an integer program. In this work, we introduce the tree compression problem (TCP): Given a BB tree T that certif…
Exploiting Instance and Variable Similarity to Improve Learning-Enhanced Branching
Xiaoyi Gu, Santanu S. Dey, Álinson S. Xavier +1
In many operational applications, it is necessary to routinely find, within a very limited time window, provably good solutions to challenging mixed-integer linear programming (MIL…
Decomposable Formulation of Transmission Constraints for Decentralized Power Systems Optimization
Alinson S. Xavier, Feng Qiu, Santanu S. Dey
One of the most complicating factors in decentralized optimization for power systems is the modeling of power flow equations. Existing formulations for DC power flows either have l…
Learning to Solve Large-Scale Security-Constrained Unit Commitment Problems
Alinson S. Xavier, Feng Qiu, Shabbir Ahmed
Security-Constrained Unit Commitment (SCUC) is a fundamental problem in power systems and electricity markets. In practical settings, SCUC is repeatedly solved via Mixed-Integer Li…
