Enhanced weather modelling for dynamic line rating [PDF]

open access: yes, 2018
Conventional approaches to dynamic line rating (DLR) forecasting provide single point estimates with no indication of the distribution of possible errors. Furthermore, most research related to DLR forecasting deals only with continuous or steady-state ratings while less attention has been given to short-term or transient-state ratings.

Empirical Capital Structure Research: New Ideas, Recent Evidence, and Methodological Issues [PDF]

open access: yes, 2008
Even 50 years after Modigliani/Miller’s irrelevance theorem, the basic question of how firms choose their capital structure remains unclear. This survey paper aims at summarizing and discussing corresponding recent developments in empirical capital ...

Dynamic Matrix Factorization with Priors on Unknown Values

open access: yes, 2015
Advanced and effective collaborative filtering methods based on explicit feedback assume that unknown ratings do not follow the same model as the observed ones (\emph{not missing at random}).

An Enhanced Algorithm for Conventional Protection Devices of Transmission Lines With DTLR

open access: yesIEEE Access, 2021
As the installed capacity of renewable generation continues to increase nowadays to satisfy both emissions and economic requirements, the nature of intermittent generation results in a need to further increase transmission capacity.

Increasing the Utilization of Transmission Lines Capacity by Quasi-Dynamic Thermal Ratings

open access: yesEnergies, 2019
The power grid is under pressure to maintain a reliable supply because of constrained budgets and environmental policies. In order to effectively make use of existing transmission lines, it is important to accurately evaluate the line capacity.
