Risk–Based Admissibility Analysis of Wind Power Integration into Power System With Energy Storage System

open access: yesIEEE Access, 2018
The increasing high penetration of wind power will further increase the uncertainty in power systems, and three key issues should be addressed: 1) determining the maximum accommodation level of wind power without sacrificing system reliability; 2 ...

Equivalent Modeling of Dfig-Based Wind Farms for Sub-Synchronous Resonance Analysis

open access: yesEnergies, 2020
The order of the detailed model of doubly-fed induction generator (DFIG) wind farms are too high and the simulation is difficult. Most of the existing research has used a single-machine equivalent model and clustering aggregation model for equivalence ...

Parent Quality of Life at Two Years Following Their Child's Completion of Acute Lymphoblastic Leukemia Treatment

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Parents of children treated for acute lymphoblastic leukemia (ALL) often experience significant caregiver burden and disruption to their well‐being. While parent quality of life (QoL) during treatment is well characterized, little is known about outcomes during early survivorship.

USER-ORIENTED POWER SYSTEM CONTROL

open access: yesIFAC Proceedings Volumes, 1987
Abstract The aim of power system control is to translate the behaviour of a power system under all operating conditions with respect to time and information in a form to which the operator can respond. Starting by defining the duties and needs of the operator in the different operational states, an attempt is made to list the “user oriented ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
