A Closed Time-Reversal Cavity for Electromagnetic Waves in Transmission Line Networks
Mario Paolone, Marcos Rubinstein, Zhaoyang Wang, Reza Razzaghi
A closed time-reversal cavity has been considered a purely theoretical concept whose experimental realization was assumed to be impossible. In this paper, we demonstrate that it is, in fact, possible to realize a closed time-reversal cavity using a network ...
2020Hierarchical Control in Islanded DC Microgrids With Flexible Structures
Giancarlo Ferrari Trecate, Pulkit Nahata, Alessio La Bella
Hierarchical architectures stacking primary, secondary, and tertiary layers are widely employed for the operation and control of islanded dc microgrids (dcmGs) composed of distribution generation units (DGUs), loads, and power lines. However, a comprehensi ...
2020Multi-level high-voltage power supply for dea application
Yves Perriard, Yoan René Cyrille Civet, Morgan Almanza, Lucas Pniak, Lucas Depreux
In order to reap the benefits of Dielectric Elastomer Actuator (DEA) high energy density, the electronics powering the actuator should be as small as possible. Knowing that only a small fraction of the energy delivered to DEAs is effectively converted into ...
2019Galvanically Isolated Modular Converter
The ever increasing penetration of renewable energy systems in the distribution grids will inevitably require profound changes in the grid infrastructure. One emerging direction, the medium voltage dc (MVdc) grids, is the cornerstone of this work. They are ...
EPFL2018Six-Step MMC-Based High Power DC-DC Converter
Drazen Dujic, Stefan Milovanovic
Roth DC collection and transmission grids have enjoyed a lot of popularity lately. In order to successfully take advantage of the benefits offered by DC systems, reliable connection between two networks of different voltage levels has to be obtained. This ...
IEEE2018Voltage Stabilization in MVDC Microgrids Using Passivity-Based Nonlinear Control
Giancarlo Ferrari Trecate, Pulkit Nahata, Andrea Martinelli
This paper investigates the application of passivity-based nonlinear control to the problem of primary voltage stabilization in medium-voltage DC microgrids (MVDC mGs) given by the interconnection of nonlinear distributed generation units (DGUs) and power ...
IEEE2018Medium Voltage DC-DC Converter for Power Collection Links
Nowadays electrical energy generation is an important topic discussed in the society. Since technologies like wind or solar energy generation are most of the time placed far away from the city centres one point to focus on is the transmission of the energy ...
EPFL2017Model-less Measurement-based Computation of Voltage Sensitivities in Unbalanced Electrical Distribution Networks
Mario Paolone, Konstantina Christakou, Mauro Carpita, Carl Emile Mugnier
Within the context of microgrids optimal voltage control, most schemes proposed in the literature either rely on (i) droop-control methods or (ii) methods involving the computation of explicit nodal power set-points as a solution to a given optimization pr ...
Università degli Studi di Genova, Italy2016Static and recursive PMU-based state estimation processes for transmission and distribution power grids
Jean-Yves Le Boudec, Mario Paolone, Lorenzo Zanni, Styliani Sarri
In the operation of power systems, the knowledge of the system state is required by several fundamental functions, such as security assessment, voltage control and stability analysis. By making reference to the static state of the system represented by the ...
