Power management of islanded Self-Excited Induction Generator reinforced by energy storage systems [PDF]
, 2018 Self-Excited Induction Generators (SEIGs), e.g., Small-Scale Embedded wind generation, are increasingly used in electricity distribution networks. The operational stability of stand-alone SEIG is constrained by the local load conditions: stability can be

A VSC-based Model for Power Flow Assessment of Multi-terminal VSC-HVDC Transmission Systems [PDF]
Journal of Modern Power Systems and Clean Energy, 2021 This paper puts forward a new practical voltage source converter (VSC) based AC-DC converter model suitable for conducting power flow assessment of multi-terminal VSC-based high-voltage direct current (VSC-MTDC) systems. The model uses an advanced method to handle the operational limits and control modes of VSCs into the power flow formulation. The new

Vagal nerve stimulation therapy: what is being stimulated? [PDF]
, 2014 Vagal nerve stimulation in cardiac therapy involves delivering electrical current to the vagal sympathetic complex in patients experiencing heart failure. The therapy has shown promise but the mechanisms by which any benefit accrues is not understood. In
