Fuel constrained unit commitment
IEEE Transactions on Power Systems, 1992The authors present a generalized method of solving the unit commitment problem with fuel constraints. The fuel-constrained unit commitment problem is decomposed into a linear fuel dispatch (FD) problem and a unit commitment (UC) problem. The FD problem optimizes system fuel cost while satisfying fuel constraints and unit fuel requirements.

Environmentally constrained unit commitment
IEE Proceedings C Generation, Transmission and Distribution, 1992The authors present a short-term unit-commitment algorithm. They include a new function for managing SO/sub 2/ emissions from fossil-fuel-fired generating units. The method uses a Lagrangian-relaxation-based algorithm which offers a new approach for the commitment of realistically sized systems. Emission is considered as a second objective function and

Stochastic unit commitment problem
International Transactions in Operational Research, 2003AbstractThe electric power industry is undergoing restructuring and deregulation. We need to incorporate the uncertainty of electric power demand or power generators into the unit commitment problem. The unit commitment problem is to determine the schedule of power generating units and the generating level of each unit. The objective is to minimize the

Wasserstein Metric Based Distributionally Robust Approximate Framework for Unit Commitment
IEEE Transactions on Power Systems, 2019This paper proposed a Wasserstein metric-based distributionally robust approximate framework (WDRA), for unit commitment problem to manage the risk from uncertain wind power forecasted errors.

2007 IEEE Power Engineering Society General Meeting, 2007
In this paper, a risk-based unit commitment (RBUC) approach for the day-ahead market is introduced. A risk-based economic dispatch, an independent part of the risk- based unit commitment, can be used for the real-time market. This provides for consideration of both economic benefit as well as reliability within a single integrated approach.

Proceedings of the 39th Midwest Symposium on Circuits and Systems, 2002
In this paper, an algorithm based on a heuristic approach has been developed to perform short term unit commitment. The proposed algorithm consists of several reasoning loops to generate a schedule that satisfies all given constraints. The decisions from these loops are based on a partial priority list method and some appropriate heuristic rules.

Which Unit-Commitment Formulation is Best? A Comparison Framework
IEEE Transactions on Power Systems, 2020The Unit Commitment (UC) problem, which determines the day-ahead dispatch of generation units, is one of the critical problems in power systems operation.

Cooperative Coevolutionary Algorithm for Unit Commitment
IEEE Power Engineering Review, 2002This paper presents a new cooperative coevolutionary algorithm (CCA) for power system unit commitment. CCA is an extension of the traditional genetic algorithm (GA) which appears to have considerable potential for formulating and solving more complex problems by explicitly modeling the coevolution of cooperating species.

Unit Commitment With Inertia-Dependent and Multispeed Allocation of Frequency Response Services
IEEE Transactions on Power Systems, 2019Future changes in the generation mix may reduce the overall amount of system inertia. It becomes crucial to provide response services more quickly to secure postfault transient frequency dynamics.
