African trypanosomes evade the immune system of the mammalian host by the antigenic variation of the predominant glycosylphosphatidylinositol (GPI)-anchored surface protein, variant surface glycoprotein (VSG).

Current-Limiting VSG for Renewable Energy Applications
In this paper, an improved nonlinear controller structure, which inherits both virtual inertia (VI) and current-limiting properties in grid-connected voltage-source converters (VSCs), is proposed. The proposed method inherits the V dc ~ ω droop control for inertia emulation and frequency control, and Q ~ V droop control for AC voltage support.

When multiple Virtual Synchronous Generators (VSGs) operate in parallel in an islanded grid, power and frequency oscillations will occur when one VSG goes offline.

Mapping of VSG similarities in Trypanosoma brucei [PDF]
The protozoan parasite Trypanosoma brucei switches its variant surface glycoprotein (VSG) to subvert its mammalian hosts' immune responses. The T. brucei genome contains as many as 1600 VSG genes (VSGs), but most are silent noncoding pseudogenes. Only one functional VSG, located in a telomere-linked expression site, is transcribed at a time.

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

Research of inverter parallel control based on improved parameter adaptive VSG
Virtual synchronous generators (VSG) technology is widely used in grid-connected and multi-machine parallel control strategies for inverter systems because of its ability to simulate synchronous generators and make distributed power sources also have ...

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

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