Exploiting flexibility of combined-cycle gas turbines in power system unit commitment with natural gas transmission constraints and reserve scheduling

Tao Jiang et al.

Summary: This paper proposes a unit commitment model considering natural gas transmission constraints and reserve scheduling to reduce wind power curtailment and high startup-shutdown cost of conventional generation units. The effectiveness of the proposed model is demonstrated through case studies.

Learning to Solve Large-Scale Security-Constrained Unit Commitment Problems

Alinson S. Xavier et al.

Summary: This paper introduces a novel computational method combining mixed-integer linear programming (MILP) and machine learning (ML) to solve a challenging and fundamental optimization problem in the energy sector. The proposed method not only advances the state-of-the-art for the specific problem discussed, but also in solving discrete optimization problems using ML in general. The techniques presented are expected to be readily applicable for practitioners in the energy sector and adaptable by researchers in other fields dealing with routinely solved challenging operations research problems.
