Improved Load Frequency Control Design for Interconnected Power Systems

Energies
Managing frequency stability in modern interconnected power systems is a critical challenge, particularly under continuous load variations and increasing system complexity.

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

FEBS 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.

HDE-CGWO-Based Optimal Load Frequency Control for Nonlinear Power Systems

Energies
In modern power-system load frequency control (LFC), proportional–integral–derivative (PID) controllers are widely used because of their simple structure and ease of implementation.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

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

FEBS 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.

Blinded by the load: attention, awareness and the role of perceptual load. [PDF]

, 2014
What is the relationship between attention and conscious awareness? Awareness sometimes appears to be restricted to the contents of focused attention, yet at other times irrelevant distractors will dominate awareness.

Analysis of the Impacts of the Interaction Between Frequency-Dependent Loads and Virtual Inertia Control in an Isolated Microgrid

IEEE Access
Inverter-dominated microgrids are highly sensitive to disturbances owing to their low inertia. The accepted solution is to provide virtual inertia for frequency support.

Enhanced load frequency control: incorporating locational information for temporal enhancement

IET Generation, Transmission & Distribution, 2019
With the increasing penetration of renewables in power systems, frequency regulation is proving to be a major challenge for system operators using slower conventional generation, and alternative means to provide faster regulation are being actively ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Using electric vehicle fleet as responsive demand for power system frequency support [PDF]

, 2013
Based on conventional car driving patterns, it has been recognized that typically a car remains stationary for 95% of the time, only being driven on the road for the remaining 5% of that time on average.
