A Polyhedral-Based Approach Applied to Quadratic Cost Curves in the Unit Commitment Problem
(IEEE, 2016)
This paper presents a new polyhedral approximation for the quadratic cost curve of thermal units for the unit commitment problem. The approximation is tight, can be represented by rational numbers, and its size grows ...
Security-Constrained Unit Commitment Problem including thermal and pumped storage units: An MILP formulation by the application of linear approximations techniques
(Elsevier Science Sa, 2018-01)
This paper presents a new approach for solving Security Constrained Unit Commitment (SCUC) problems based on the application of several linear approximation techniques. Model considers thermal units, transmission constraints, ...

Stochastic Unit Commitment & Optimal Allocation of Reserves: A Hybrid Decomposition Approach
(Institute of Electrical and Electronics Engineers, 2018-09)
The unit commitment is still a widely studied problem, especially when more renewable energy of stochastic character is being added to power systems. This paper proposes a model for weekly planning of systems involving ...
Short-term hydrothermal generation scheduling model using a genetic algorithm
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2003)
A new model to deal with the short-term generation scheduling problem for hydrothermal systems is proposed. Using genetic algorithms (GAs), the model handles simultaneously the subproblems of short-term hydrothermal ...
Day-ahead unit commitment for hydro-thermal coordination with high participation of wind power
(Institution of Engineering and Technology (IET)Tianjin University, 2022)
The variability and uncertainty of renewable resources impose new challenges in the
operational planning related to the unit commitment of generation units. The development
of day‐ahead multi‐period optimal power flow, ...
