On Mixed-Integer Programming Formulations for the Unit Commitment Problem

open access: yesINFORMS journal on computing, 2020
We provide a comprehensive overview of mixed-integer programming formulations for the unit commitment (UC) problem. UC formulations have been an especially active area of research over the past 12 years due to their practical importance in power grid ...

Unit commitment based on modified firefly algorithm

open access: yesMeasurement + Control, 2020
Optimization technologies have drawn considerable interest in power system research. The success of an optimization process depends on the efficient selection of method and its parameters based on the problem to be solved. Firefly algorithm is a suitable

A novel heuristic optimisation algorithm for solving profit-based unit commitment for thermal power generation with emission limitations

open access: yesInternational Journal of Sustainable Energy, 2022
The profit-based unit commitment is a maximisation problem, which consists of the revenue minus costs subject to related constraints. However, with increasing concerns for the global warming, environmental limitations must also be observed. The objective

Stochastic Unit Commitment in Low-Inertia Grids [PDF]

open access: yesIEEE Transactions on Power Systems, 2019
In this paper, the Unit Commitment (UC) problem in a power network with low levels of rotational inertia is studied. Frequency-related constraints, namely the limitation on Rate-of-Change-of-Frequency (RoCoF), frequency nadir and steady-state frequency ...

Employee Attributions of the Why of HR Practices: Their Effects on Employee Attitudes and Behaviors, and Customer Satisfaction [PDF]

open access: yes, 2007
The construct of Human Resource (HR) Attributions is introduced. We argue that the attributions that employees make about the reasons why management adopts the HR practices that it does have consequences for their attitudes and behaviors, and ultimately,

Binary glowworm swarm optimization for unit commitment

open access: yesJournal of Modern Power Systems and Clean Energy, 2014
This paper proposes a new algorithm-binary glowworm swarm optimization (BGSO) to solve the unit commitment (UC) problem. After a certain quantity of initial feasible solutions is obtained by using the priority list and the decommitment of redundant unit,
