Radial movement optimization (RMO) technique for solving unit commitment problem in power systems

Journal of Electrical Systems and Information Technology, 2018
Unit commitment (UC) is one of the nonlinear optimization problems with linear and nonlinear constraints. In this work, radial movement optimization (RMO) is employed to solve the optimal thermal unit commitment problem. Radial movement optimization is a

A Cross-Entropy-Based Hybrid Membrane Computing Method for Power System Unit Commitment Problems

Energies, 2019
The cross-entropy based hybrid membrane computing method is proposed in this paper to solve the power system unit commitment problem. The traditional unit commitment problem can be usually decomposed into a bi-level optimization problem including unit ...

Hybrid Ship Unit Commitment with Demand Prediction and Model Predictive Control

Energies, 2020
We present a novel methodology for the control of power unit commitment in complex ship energy systems. The usage of this method is demonstrated with a case study, where measured data was used from a cruise ship operating in the Caribbean and the ...

The influence of leader-member exchange differentiation on work unit commitment: the mediating role of support climate

Psychologica, 2019
We investigated whether the influence of LMX differentiation (the extent to which the quality of the leader-member relationships within a work unit varies) on work unit commitment is mediated by support climate.

Work-Unit Absenteeism: Effects of Satisfaction, Commitment, Labor Market Conditions, and Time [PDF]

, 2008
Prior research is limited in explaining absenteeism at the unit level and over time. We developed and tested a model of unit-level absenteeism using five waves of data collected over six years from 115 work units in a large state agency.
