Summary: The discussion of energy efficiency in steel ladle dispatching has been limited in the existing literature. This paper proposes a solution that takes into account the thermal balance of the ladle and presents a mixed integer linear problem for ladle dispatching. By using advanced mixed integer programming solvers, the problem can be globally solved. The computational results show the impact of the number of breakpoints on the approximation quality and solution time. However, the error doesn't affect the feasibility of the problem significantly. In an experiment conducted with Tata Steel, IJmuiden, operational rules are defined and potential energy savings are discussed. The average steel temperature losses can be reduced by up to 3 degrees Celsius depending on the refractory temperature requirement, which can lead to further savings for steelmakers.

Summary: This paper introduces a new network-constrained unit commitment model, formulated as a mixed-integer linear programming problem with embedded AC-PF constraints, which ensures the UC dispatch schedule within permissible transmission capacity and voltage deviation limits. The proposed model is tested on actual systems and validated against DIgSILENT/Powerfactory package, with detailed results compared to existing literature employing different UC+AC-PF models for the same test systems.

Summary: This paper proposes a model called DPWLPF for optimizing power flow problems in transmission systems. The P-Q decoupling characteristic reduces the coupling between variables and an UVLS method based on DPWLPF is presented. For large systems, DPWLPF outperforms conventional piecewise models.

Summary: This study proposes a method to alleviate errors in the charging/discharging scheduling process of a battery energy storage system (BESS) caused by its nonlinear characteristics. The proposed model, using the special ordered set of type 2 method, effectively reduces the error in charging/discharging energy in comparison to the typical model. The study demonstrates that this method efficiently solves operational problems caused by the nonlinear characteristics of BESS.

Summary: In this paper, a unified mixed-integer linear programming (MILP) solution framework is proposed to mitigate the high computational cost of adaptive robust optimization with a mixed-integer recourse objective in real-world power scheduling. Numerical tests verify the superiority and practicability of the proposed solution framework over the existing decomposition-based solution algorithms.

Summary: The growing demand for electricity and reconstruction in Africa necessitates an effective and reliable energy supply system. The construction of reliable, clean, and affordable microgrids, whether isolated or connected to the main grid, is crucial for addressing energy supply issues in remote desert areas. This paper investigates the establishment of an efficient and cost-effective microgrid in the Djado Plateau of northeastern Niger. The study compares three cases and identifies the second case as the best option in terms of total life cycle cost and independence from the main grid, with a 11.19% lower life cycle cost compared to the first case and a 5.664% lower cost compared to the first scenario of the third case.

Summary: This paper compares two recent studies in the INFORMS Journal on Computing that present mixed-integer linear programming models. Both models have similar formulations, and a detailed comparison is conducted across 10 datasets. Although neither model is superior on all datasets, experimental results suggest that the formulation presented by Rebennack and Krasko is faster.

Summary: This paper aims to develop a rigorous mathematical framework, based on mixed integer programming, for the analysis of the cortical vision prosthesis design problem and the optimal estimation of a prosthesis setup parameters. The simulated examples illustrate the unique capabilities of the proposed strategy in testing the feasibility of the goals of a prosthesis under a set of specified design constraints. Future research should focus on how these electrodes can be safely implanted, and once this is possible, the proposed framework can be applied to decide their optimal locations and excitation currents.

Summary: This paper investigates the optimal power-gas flow (OPGF) problem, considering the nonlinear AC power flow model and nonconvex gas flow model. To address the nonconvexity problem, the concept of successive linearization is introduced and a successive mixed-integer quadratic programming (SMIQP) method is developed. Numerical results demonstrate the effectiveness of the proposed method in terms of accuracy and computational efficiency.

Summary: This paper proposes a method to solve the optimal transmission switching problem (OTSP) by changing the topology of a power grid to improve dispatch. The method uses parallel heuristics to generate candidate solutions and combines them with branch-and-bound (B & B) algorithms. Experimental results show that the method performs well on large problem instances and consistently improves upon off-the-shelf solver performance.
