Stabilization of grid frequency through dynamic demand control

, 2007
Frequency stability in electricity networks is essential to the maintenance of supply quality and security. This paper investigates whether a degree of built-in frequency stability could be provided by incorporating dynamic demand control into certain ...

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Coordinated control between a grid forming inverter and grid following inverters suppling power in a standalone microgrid

Global Energy Interconnection, 2022
Battery energy storage systems, fuel cells, and photovoltaic generators are being adopted in distribution networks to achieve CO2 emission reduction. These power sources require inverters to connect to AC networks.

Predicting the performance of globus monitoring and discovery service (MDS-2) queries [PDF]

, 2003
Resource discovery and monitoring in a distributed Grid environment gives rise to several issues, one of which is the provision of reliable performance and hence, the quality-of-service delivered to Grid users.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Grid-Forming: A Control Approach to Go Further Offshore?

Electricity
Offshore wind farms are increasingly being commissioned farther from shore, and high voltage alternating current (HVAC) transmission systems are preferred because of their maturity and reliability.

Grid-Following and Grid-Forming Control in Power Electronic Based Power Systems: A Comparative Study [PDF]

, 2021
The stability of frequency is at risk with increasing penetration of power electronic converters. In this case, the power grid will lack the moment of inertia to maintain a stable voltage and frequency in the event of a large disturbance.

Evaluating the involvement of autolysosomes in the nuclear translocation of fluorescent proteins

FEBS Open Bio, EarlyView.
Endogenously expressed fluorescent proteins can be degraded by autophagy and transported to cell nuclei via the nuclear pore complex. But in some cell lines, for example, HeLa cells which are positive for immunoreactivity of a receptor ligand, such as UCN I, in cell nuclei, fusion of autolysosome with the nuclear envelope is involved in the nuclear ...

Dynamic Interaction and Stability Analysis of Grid-following Converter Integrated Into Weak Grid

CSEE Journal of Power and Energy Systems
The grid-connected converter with grid-following control (GCC-GFL) for renewable energy sources has a risk of instability when integrated into the weak grid. This paper aims to investigate the dynamic interactions and stability characteristics of the GCC-

Hybrid Voltage-Current Control of Grid-Forming and Grid-Following Inverters

CoRR
Grid-connected inverters are required to operate stably under a wide range of grid conditions. However, conventional grid-following (GFL) control may suffer from instability under weak-grid conditions, while grid-forming (GFM) control may exhibit unstable oscillations under strong-grid conditions.
