Cooperative Voltage Control in AC Microgrids [PDF]

2018 IEEE Conference on Decision and Control (CDC), 2018
This paper proposes a novel control scheme based on the joint use of decentralized Sliding Mode (SM) control and distributed averaging control for cooperative voltage regulation in Alternate Current (AC) microgrids. The considered model of the microgrid includes several Distributed Generation Units (DGUs) interconnected through resistive-inductive ...

Control Strategies for Open-End Winding Drives Operating in the Flux-Weakening Region [PDF]

, 2013
This paper presents and compares control strategies for three-phase open-end winding drives operating in the flux-weakening region. A six-leg inverter with a single dc-link is associated with the machine in order to use a single energy source.

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Robust multi-physics field reconstruction via sparse enclosure temperature measurements for GIL Digital Twin application

International Journal of Electrical Power & Energy Systems
Fast and reliable field reconstruction from sparse sensing is essential for real-time Digital Twin (DT) models, yet it has been overshadowed by the emphasis on fast-forward simulations within the high-voltage apparatus community, despite both approaches ...

Effect of Fe3O4 nanoparticles on positive streamer propagation in transformer oil

AIP Advances, 2016
Fe3O4 nanoparticles with an average diameter of 10 nm were prepared and used to modify streamer characteristic of transformer oil. It was found that positive streamer propagation velocity in transformer oil-based Fe3O4 nanofluid is greatly reduced by 51%
