The paper presents an automatic power management system (PMS) designed for the on-line operation of an experimental low voltage microgrid equipped with two power supplies, a kW-class fuel cell (FC) and a photovoltaic (PV) module emulator, along with a 100- ...
The paper introduces an advanced multilevel-based power converter structure for flexible power management of future electricity networks. The structure is then analysed so that appropriate control approaches are proposed in order to overcome technical chal ...
Using a finite element (FE) model of the electrical machine in a grid solver enables us to take the machine nonlinearities into account with great precision in the simulation of a complete system. Three methods are usually used for linking the grid and FE ...
This paper introduces a microelectronic emulation approach for high-speed power system computation. First, the problems of existing power system simulators are detailed. This shows that microelectronic emulation is a possible solution for the speed problem ...

This paper presents a decentralized control strategy for the autonomous (islanded) operation of parallel connection of two distributed generation (DG) units. The DG units are electronically interfaced to the host grid at the same point of common coupling ( ...
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 ...
Power Electronics is expected to become a major component in the field of the global electric power management, as it is already today within most of electric power applications like variable speed drives or other conventional user applications. From the e ...
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 ...
This paper proposes, for the first time, the investigation of the SG-FET small slope switch based on a hybrid numerical simulation approach combining ANSYS (TM) Multiphysics and ISE-DESSIS (TM) in a self-consistent system. The proposed hybrid numerical sim ...
