Low Voltage Ride-through in DFIG Wind Generators by Controlling the Rotor Current without Crowbars

open access: yesEnergies, 2014
Among all the different types of electric wind generators, those that are based on doubly fed induction generators, or DFIG technology, are the most vulnerable to grid faults such as voltage sags.

Low-Voltage Ride-Through Algorithm for Grid-Forming Converters

open access: yesIEEE Transactions on Power Electronics
In recent years, the increasing integration of renewable energy sources into power systems has led to significant changes in grid operation. Power electronic converters are primarily used to connect these power plants to the electrical system and, as key components in modern power systems, grid-forming (GFM) converters have emerged to provide the ...

Brain Atrophy Associated With Risk Variant rs10191329 Extends Beyond Multiple Sclerosis

open access: yesAnnals of Neurology, EarlyView.
The risk allele rs10191329*A is associated with disease severity and brain atrophy in people with multiple sclerosis (MS). We investigated the association of rs10191329 with age‐related brain atrophy in a population‐based cohort using 10,308 magnetic resonance imaging (MRI) scans of 4,815 participants aged ≥ 45 years without MS in cross‐sectional and ...

Severe, Non‐apneic Respiratory Dysfunction and Hypoxia following Generalized Convulsive Seizures

open access: yesAnnals of Neurology, EarlyView.
Objective Sudden unexpected death in epilepsy (SUDEP) is a devastating consequence of some generalized convulsive seizures (GCS). Recent work has focused on seizure related apnea as a biomarker of SUDEP risk, frequently without characterizing the adequacy of non‐apneic ventilation or identifying other dysfunctional breathing patterns.
