A multi-stage sequential load restoration method for under-frequency load shedding with electric vehicles participation

open access: yesEnergy Reports, 2023
As a low-cost and high-efficiency distributed energy storage resource, electric vehicles (EVs) play an increasingly prominent role in power system regulation.

Dual-frequency capacitive discharges: Effect of low-frequency current on electron distribution function [PDF]

open access: yes, 2018
In low-pressure dual-frequency capacitive discharges, the effect of the low-frequency current on the electron distribution function (EDF) was investigated through the particle-in-cell simulation with Monte Carlo collision model.

Coordinated control of rotor kinetic energy and pitch angle for large‐scale doubly fed induction generators participating in system primary frequency regulation

open access: yesIET Renewable Power Generation, 2021
This paper presents a control strategy of large‐scale wind‐thermal power joint primary frequency regulation. First, an integrated control strategy is established rotor kinetic energy control and pitch angle control for wind turbine generators ...

Distributed Secondary Control for Islanded MicroGrids - A Novel Approach [PDF]

open access: yes, 2014
This paper presents a novel approach to conceive the secondary control in droop-controlled MicroGrids. The conventional approach is based on restoring the frequency and amplitude deviations produced by the local droop controllers by using a MicroGrid ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

A framework for understanding student drop-out in the further education context [PDF]

open access: yes, 1996
This research represents a systematic investigation and analysis of student drop-out in a college of Further Education. Traditionally, this aspect of post-compulsory education has been under-researched. Colleges are beginning to recognise the benefits of

Communication-less primary and secondary control in inverter-interfaced AC microgrid: An overview [PDF]

open access: yes, 2021
Inverters in microgrids (MGs) face significant challenges during their parallel operations, such as accurate power sharing, deviations in system voltage magnitude and frequency, and imbalance between generation and load demand.

Frequency Coordinated Control Strategy for an HVDC Sending-End System with Wind Power Integration Based on Fuzzy Logic Control

open access: yesEnergies, 2021
Under the background of high wind power permeability, the frequency regulation capability of high voltage direct current (HVDC) sending-end system tends to deteriorate.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
