Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Inertia Support Strategy for Wind Turbine Based on Switched Operating Points With Equivalent Time Constant

IEEE Access
The wind Turbine adopts Virtual Synchronous Generator (VSG) control to support grid frequency by releasing their energy reserve. However, the interaction between the maximum power point tracking (MPPT) control and VSG control will weaken their inertia ...

Contribution of Wind Farms to the Stability of Power Systems with High Penetration of Renewables

Energies, 2021
Power system inertia is being reduced because of the increasing penetration of renewable energies, most of which use power electronic interfaces with the grid.

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.

Cost Allocation for Inertia and Frequency Response Ancillary Services

IEEE Transactions on Energy Markets, Policy and Regulation
The reduction in system inertia is creating an important market for frequency-containment Ancillary Services (AS) such as enhanced frequency response (e.g.,~provided by battery storage), traditional primary frequency response and inertia itself.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

FEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Ancillary Services Market Design in Distribution Networks: Review and Identification of Barriers

Energies, 2020
The high proliferation of converter-dominated Distributed Renewable Energy Sources (DRESs) at the distribution grid level has gradually replaced the conventional synchronous generators (SGs) of the transmission system, resulting in emerging stability and

Fuzzy control based virtual synchronous generator for self-adaptative control in hybrid microgrid

Energy Reports, 2022
Maintaining the stability of low-inertia microgrid becomes a key challenge in the presence of high penetration of renewable energy sources. However, in such systems, the virtual inertia values are often fixed constants, and the choice of their values ...
