An improved VSG control method for GFM converters based on backstepping control

Zhejiang dianli
In response to problems such as poor dynamic performance， slow response speed， and significant steady-state errors in conventional virtual synchronous generator （VSG） control when handling power command changes or sudden faults， this paper proposes an ...

A voltage regulation method for active power reserve-based grid-forming photovoltaic inverters

Zhejiang dianli
The increasing penetration of distributed photovoltaic （PV） systems in low-voltage distribution areas has led to growing voltage violations due to source-load mismatch and inadequate reactive power support.

Blocking Variant Surface Glycoprotein synthesis in Trypanosoma brucei triggers a general arrest in translation initiation

, 2009
Background: The African trypanosome Trypanosoma brucei is covered with a dense layer of Variant Surface Glycoprotein (VSG), which protects it from lysis by host complement via the alternative pathway in the mammalian bloodstream.

Trypanosoma brucei TIF2 and TRF Suppress VSG Switching Using Overlapping and Independent Mechanisms. [PDF]

PLoS ONE, 2016
Trypanosoma brucei causes debilitating human African trypanosomiasis and evades the host's immune response by regularly switching its major surface antigen, VSG, which is expressed exclusively from subtelomeric loci.

Transition Towards Inverter-based Generation with VSG Control: Low Frequency Instability Prospective

, 2023
The proliferation of inverter-based resources (IBRs) with conventional control methods can result in significant power oscillations following disturbances. This is due to insufficient inertia and lack of damping with IBRs.

Power stability control of wind-PV-battery AC microgrid based on two-parameters fuzzy VSG

Frontiers in Energy Research, 2023
Virtual synchronous generator (VSG) control addresses the issue of decreasing microgrid standby inertia caused by the rise in wind turbines and photovoltaic (PV) penetration. However, various types of perturbations occur frequently making the traditional

Thin‐Film Transistor Based Active Taxel for Multimode Tactile Perception and Fused Processing

Advanced Science, EarlyView.
Skin serves as the largest‐area organ for human and embodied intelligent robots, providing tactile interaction. An active multimode fused (AMF) artificial skin is developed using standard TFT processes, featuring 2T‐1C taxels with optical and electrostatic capacitive receptors for cross‐modal sensing.

Vertical sleeve gastrectomy reduces blood pressure and hypothalamic endoplasmic reticulum stress in mice

Disease Models & Mechanisms, 2017
Bariatric surgery, such as vertical sleeve gastrectomy (VSG), causes remarkable improvements in cardiometabolic health, including hypertension remission. However, the mechanisms responsible remain undefined and poorly studied. Therefore, we developed and
