Comparison of efficient procedures for hydropower unit commitment
Energy Reports, 2022 This paper explores three new competitive heuristic procedures, which are compared with the mixed integer linear programming (MILP), all used to commit units within a hydroplant to give the maximal electrical production during a study horizon, given the ...

Learning to Solve Large-Scale Security-Constrained Unit Commitment Problems [PDF]
INFORMS journal on computing, 2019 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 linear programming (MIP), sometimes multiple times per day, with only minor ...

Deterministic proxies for stochastic unit commitment during hurricanes
IET Generation, Transmission & Distribution, 2021 Severe weather threatens the reliability of the power supply by damaging the network. In the case of hurricanes, tens of elements may fail, which would lead to power outages.

Prices stabilization for inexact unit-commitment problems [PDF]
, 2013 International audienceA widespread and successful approach to tackle unit-commitment problems is constraint decomposition: by dualizing the linking constraints, the large-scale nonconvex problem decomposes into smaller independent subproblems.

A unit commitment study of the application of energy storage toward the integration of renewable generation [PDF]
, 2012 To examine the potential benefits of energy storage in the electric grid, a generalized unit commitment model of thermal generating units and energy storage facilities is developed.

The Significance of Time Constraints in Unit Commitment Problems
IEEE AccessElectricity market clearing models are crucial for operational and investment planning in modern power systems. Two commonly used models for market clearing are the merit-order and unit commitment models. While the merit-order employs a snapshot approach

Contingency-Constrained Unit Commitment with Post-Contingency Corrective Recourse
, 2014 We consider the problem of minimizing costs in the generation unit commitment problem, a cornerstone in electric power system operations, while enforcing an N-k-e reliability criterion. This reliability criterion is a generalization of the well-known $N$-

Time-Adaptive Unit Commitment [PDF]
IEEE Transactions on Power Systems, 2019 The short-term operation of a power system is usually planned by solving a day-ahead unit commitment problem. Due to historical reasons, the commitment of the power generating units is decided over a time horizon typically consisting of the 24 hourly periods of a day.
