Modeling and Transient Simulation of FACTS in Multi-Machine Power Systems

Jean-Jacques Simond, Basile Kawkabani, Yves Pannatier

The present paper describes the modeling of 3-level Unified Power Flow Controllers (UPFC) with their control systems for studying the steady-state and transient behavior of electrical networks equipped with FACTS devices. The control features of these devi ...

Multi-Agent Approach to Electrical Distribution Networks Control

Sébastien Rumley

A new approach to the configuration and operation of electrical distribution networks is proposed. Traditionally, the medium-voltage part of the electrical grid is operated in a centralized and static manner. In the context of electric sector deregulation ...

Hardware-in-the-Loop Simulation Software for regulator tests and optimization

Jean-Jacques Simond, Philippe Allenbach, Antoine Béguin, Stefan Keller

This paper presents a real-time extension, called SIMSEN-RT, of the simulation software SIMSEN. SIMSEN-RT allows carrying out hardware-in-the-loop (HIL) simulations of power systems using hardware regulators. It can therefore be used to fine-tune regulator ...

New Control Strategy for Three Level NPC Converter Connected to the Grid

Alfred Rufer, Aziza Benaboud

The aim of the present paper is to describe a new control strategy for a three level NPC converter connected to the grid, characterized by its high efficiency. This efficiency is achieved using a square wave modulation or SWM, which has the advantage of a ...

Near infrared absorption and room temperature photovoltaic response in AlN/GaN superlattices grown by metal-organic vapor-phase epitaxy

Nicolas Grandjean, Jean-François Carlin, Eric Feltin, Sylvain Nicolay

We report on intersubband absorption of near infrared radiation in AlN/GaN superlattice structures grown by metal-organic vapor-phase epitaxy. A good correlation between well thickness and absorption peak energy was obtained. One sample shows a photovoltai ...
