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 ...
Dynamics and Stability Analysis of a Power System With a PMSG-Based Wind Farm Performing Ancillary Services
(Institute of Electrical and Electronics Engineers, 2014-07)
This work studies the impact on power system dynamics of wind energy conversion systems based on permanent magnet synchronous generators when they perform ancillary services. The ability of modern variable-speed wind ...
Dynamics of feeding behavior: role of hypothalamic and satiety signals
(Springer, 2011)
How are rats, people, and many other omnivores able to regulate food intake both within a meal and over days and weeks? We introduce a homeostatic computational theory for eating regulation whose components can be readily ...
Operation of microgrids with conventional and virtual energy storage systems
(2022)
Distribution systems are now increasingly becoming more active due to the sustainable integration of Distributed Energy Resources (DER). While this has enabled a cleaner and more efficient generation, it has also resulted ...
Short-term synaptic plasticity regulates the level of olivocochlear inhibition to auditory hair cells
(Society for Neuroscience, 2011-10)
In the mammalian inner ear, the gain control of auditory inputs is exerted by medial olivocochlear (MOC) neurons that innervate cochlear outer hair cells (OHCs). OHCs mechanically amplify the incoming sound waves by virtue ...
Sequence features responsible for intron retention in human
(2007)
Abstract
Background
One of the least common types of alternative splicing is the complete retention of an intron in a mature ...
Improving Small-Signal Stability of Power Systems with Significant Converter-Interfaced Generation
(Institute of Electrical and Electronics Engineers, 2020-07-21)
This work presents a hierarchical control strategy to improve the stability of electrical networks with significant converter-interfaced generation (CIG). Due to the lack of inertia of CIG systems, these networks can undergo ...
Effects of vagotomy on cardiovascular and heart rate variability alterations following chronic normobaric hypoxia in adult rabbits
(2018)
Abstract
Background
chronic hypoxia increases basal ventilation and pulmonary vascular resistance, with variable changes in arterial blood pressure and heart rate, but it’s ...
As metamorfoses de rede de poder agroindustrial sucroalcooleira no Estado de São Paulo: da regulação estatal para a desregulação
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia de Produção - PPGEP, 2004-02-19)
Since the thirties, the sugar-cane section from São Paulo expanded as a policy network, where the industrialists, sugar-cane suppliers and the state interests were orchestrated. However, after the section deregulation ...
