Single-to-Three-Phase Direct AC/AC Modular Multilevel Converters with Integrated Split Battery Energy Storage for Railway Interties

Alfred Rufer, Michail Vasiladiotis, Nicolas Cherix

This paper presents a global hierarchized control method for railway interties based on the direct singleto-three-phase AC/AC Modular Multilevel Converter with integrated split battery energy storage. The power and voltage decoupling between the converter ...

Physical Mechanisms governing Self-Excited Pressure Oscillations in Francis Turbines

Andres Müller

The importance of renewable energy sources for the electrical power supply has grown rapidly in the past decades. Their often unpredictable nature however poses a threat to the stability of the existing electric grid. Hydroelectric powerplants play an impo ...

Primary Voltage Control in Active Distribution Networks via Broadcast Signals: The Case of Distributed Storage

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

In this paper, we consider an active distribution network (ADN) that performs primary voltage control using real-time demand response via a broadcast low-rate communication signal. The ADN also owns distributed electrical energy storage. We show that it is ...

A Cascade Voltage Controller for Three-phase Islanded Microgrids

Alfred Rufer, Behrooz Bahrani

This paper proposes a cascade or multiloop digital control strategy for the voltage regulation of a three-phase islanded single distributed generation (DG) unit microgrid and its dedicated load. The cascade control strategy consists of an inner dq-currents ...

Balancing Control Actions for Cascaded H-Bridge Converters with Integrated Battery Energy Storage

Alfred Rufer, Michail Vasiladiotis

This paper investigates the ways to handle active power components for control and balancing purposes in three-phase Cascaded H-Bridge converters with embedded battery energy storage systems. The split storage elements are interfaced to the converter modul ...

A Multivariable Design Methodology for Voltage Control of a Single-DG-Unit Microgrid

Alfred Rufer, Alireza Karimi, Behrooz Bahrani

This paper proposes a multivariable digital control design methodology for the voltage regulation of an islanded single distributed generation (DG) unit microgrid and its dedicated load. The controller design methodology is based on a family of spectral Mu ...

CoFeed: privacy-preserving Web search recommendation based on collaborative aggregation of interest feedback

Martin Rajman, Vinh Toan Luu, Pascal Felber

Search engines essentially rely on the structure of the graph of hyperlinks. Although accurate for the main trend, this is not effective when some query is ambiguous. Leveraging semantic information by the mean of interest matching allows proposing complem ...

The Facilitation of Mini and Small Hydropower in Switzerland : Shaping the Institutional Framework (with a Particular Focus on Storage and Pumped-Storage Schemes)

Nicolas Crettenand

The electricity sector in Switzerland is undergoing important changes following the liberalisation process and the facilitation of renewable energy technologies. Furthermore, the phasing out of nuclear power will increase the demand for new domestic electr ...

Optimization of electric shunt resonant circuits for electroacoustic absorbers

Hervé Lissek, Romain Boulandet, Etienne Thierry Jean-Luc Rivet

Sound absorption can be achieved in a relatively simple manner with passive or active electroacoustic absorbers. Electroacoustic absorbers are basically loudspeakers, the membrane of which is used as an absorber/reflector of sound, and the electric termina ...

Autonomic SLA-driven Provisioning for Cloud Applications

Karl Aberer, Nicolas Bonvin

Significant achievements have been made for automated allocation of cloud resources. However, the performance of applications may be poor in peak load periods, unless their cloud resources are dynamically adjusted. Moreover, although cloud resources dedica ...
