Energy and Reserve Management in Interconnected Systems including Electric Railway and Public Power Grids

Mokhtar Bozorg

For historical reasons, the frequency of Electric Railway Power System (ERPS) in central European countries (e.g., Switzerland, Germany and Austria) is different from the frequency of the public power grid. To feed such a low frequency (i.e., 16.7 Hz) syst ...

AC OPF in Radial Distribution Networks - Parts I,II

Jean-Yves Le Boudec, Mario Paolone, Dan-Cristian Tomozei, Konstantina Christakou

The optimal power-flow problem (OPF) has always played a key role in the planning and operation of power systems. Due to the non-linear nature of the AC power-flow equations, the OPF problem is known to be non-convex, therefore hard to solve. Most proposed ...

Cloaking via anomalous localized resonance. A connection between the localized resonance and the blow up of the power for doubly complementary media

Hoài-Minh Nguyên

This paper is devoted to the study of cloaking via anomalous localized resonance (CALR) in two and three dimensions in the quasistatic regime. Two key figures of CALR are (i) the localized resonance and (ii) the connection between the localized resonance a ...

Dielectric elastomer generators that stack up

Herbert Shea, Samuel Rosset

This paper reports the design, fabrication, and testing of a soft dielectric elastomer power generator with a volume of less than 1 cm3. The generator is well suited to harvest energy from ambient and from human body motion as it can harvest from low frequ ...

Impact of a narrow limiter SOL heat flux channel on the ITER first wall panel shaping

Ivo Furno, Benoît Labit, Richard Pitts, Jan Horacek, Federico Nespoli, Cedric Kar-Wai Tsui, Gilles Arnoux

he inboard limiters for ITER were initially designed on the assumption that the parallel heat flux density in the scrape-off layer (SOL) could be approximated by a single exponential with decay length λq. This assumption was found not to be adequate i ...

Power-Thermal Modeling and Control of Energy-Efficient Servers and Datacenters

David Atienza Alonso, Martino Ruggiero, Mohamed Sabry Abdel-Aliem Mohamed, Jungsoo Kim

Recently, the energy-efficiency constraints have become the dominant limiting factor for datacenters due to their unprecedented increase of growing size and electrical power demands. In this chapter we explain the power and thermal modeling and control sol ...

Leader corruption depends on power and testosterone

Samuel Bendahan, John Antonakis

We used incentivized experimental games to manipulate leader power - the number of followers and the discretion leaders had to enforce their will. Leaders had complete autonomy in deciding payouts to themselves and their followers. Although leaders could m ...

Design Methodology for Common-Mode Stability of OTA-based Gyrators

Pierre-André Farine, Cyril Botteron, Gabriele Tasselli, Saeed Ghamari

This paper presents a design methodology for common-mode (CM) stability of operational transconductance ampliﬁer (OTA)-based gyrators. The topology of gm−C active inductors is brieﬂy reviewed. Subsequently, a comprehensive mathematical analysis on the CM s ...

R&D around a photoneutralizer-based NBI system (Siphore) in view of a DEMO Tokamak steady state fusion reactor

Ivo Furno, Alan Howling, Philippe Frédérique Bruno Guittienne, Rémy Jacquier

Since the signature of the ITER treaty in 2006, a new research programme targeting the emergence of a new generation of neutral beam (NB) system for the future fusion reactor (DEMO Tokamak) has been underway between several laboratories in Europe. The spec ...
