Binary glowworm swarm optimization for unit commitment

Journal 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,

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

, 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,

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

International 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

Unit commitment with transmission constraints in deregulated power market [PDF]

, 2015
As the power industry across the world is undergoing a radical change by separation of transmission from generation activities, scope of competition by bidding or through provision of bilateral transactions in spot markets exists between different market

Work-related moderators of the relationship between organizational change and sickness absence: a longitudinal multilevel study

BMC Public Health, 2020
Background A sizeable body of research has demonstrated a relationship between organizational change and increased sickness absence. However, fewer studies have investigated what factors might mitigate this relationship.

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 ...

Reinforcement Learning for the Unit Commitment Problem

, 2015
In this work we solve the day-ahead unit commitment (UC) problem, by formulating it as a Markov decision process (MDP) and finding a low-cost policy for generation scheduling. We present two reinforcement learning algorithms, and devise a third one.

An effective hybrid decomposition approach to solve the network-constrained stochastic unit commitment problem in large-scale power systems

EURO Journal on Computational Optimization
We propose a novel hybrid method to solve the network-constrained stochastic unit commitment problem. We target realistic large-scale instances including hundreds of thermal generation units, thousands of transmission lines and nodes, and a large number ...

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.
