Thyristor-based flexible ac transmission system for controlling the vanadium redox flow battery
(Inst Engineering Technology-iet, 2013-05)
The vanadium redox flow battery (VRB) is a large stationary energy storage system; which presents high-speed response and overload capacity characteristics. The VRB produces a dc voltage between two terminals; so a power ...

LAMDA-HAD, an Extension to the LAMDA Classifier in the Context of Supervised Learning
(World Scientific Publishing Co, 2020-01-01)
This paper proposes a new approach to improve the performance of Learning Algorithm for Multivariable Data Analysis (LAMDA). This algorithm can be used for supervised and unsupervised learning, based on the calculation of ...
Control of a three-stage medium voltage solid-state transformer
(ASTES, 2017-12-07)
This paper proposes the modeling and control of a Solid-State Transformer using a three-stage conversion topology. First, a rectification stage is used, where a three-phase high-voltage AC signal is converted to a DC level; ...

Hierarchical Wide-Area Control of Power Systems Including Wind Farms and FACTS for Short-Term Frequency Regulation
(Institute of Electrical and Electronics Engineers, 2012-11)
In this work a hierarchical scheme is proposed for the coordinated control of conventional synchronous generators, wind farm converters and flexible ac transmission systems. It comprises two levels, namely a fully decentralized ...
Short-Term Frequency Regulation and Inertia Emulation Using an MMC-Based MTDC System
(Institute of Electrical and Electronics Engineers, 2018-05)
The continuous displacement of conventional power plants by converter-interfaced generation systems reduces the system inertia and may lead to a degradation of the frequency stabili-Leon-2757258ty. A supplementary control ...
Neutrophil elastase converts human immature dendritic cells into transforming growth factor-β1-secreting cells and reduces allostimulatory ability
(American Society of Investigative Pathology, 2007-12)
During microbial infection, neutrophils (polymorphonuclear leukocytes; PMNs) activate dendritic cells (DCs). However, early reports illustrated that neutrophil-derived mediators may suppress responses to mitogens. In the ...
