DC Power Distribution Networks with Direct Current Transformers
The shift towards DC power distribution networks, enabled by power electronics technologies, is changing the nature of electrical power systems. Nowadays, DC power distribution networks can effectively support the high penetration of distributed energy res ...
EPFL2024DC Transformer Impact on Voltage Dynamics in Hybrid AC-DC Power Distribution Networks
Drazen Dujic, Andrea Cervone, Jules Christian Georges Macé, Max Dupont, Renan Pillon Barcelos
AC/DC power distribution networks use various types of power converters to interconnect their buses, active front ends between AC and DC buses, and DC transformers between DC buses. Different active front end control methods, like voltage or power regulati ...
VDE Verlag2023Dynamics analysis for DC transformers integration in hybrid AC‐DC power distribution networks
Drazen Dujic, Andrea Cervone, Jules Christian Georges Macé, Max Dupont, Renan Pillon Barcelos
In AC/DC power distributions networks, power converters are interfacing buses to ensure DC voltage regulation and power distribution. Active front ends are used between AC and DC buses and two typical control schemes that can be implemented are voltage reg ...
2023A Lightweight Device for Energy Harvesting from Power Lines with a Fixed-Wing UAV
Dario Floreano, William John Stewart
Modern UAVs (Unmanned Aerial Vehicles) suffer from restrictions in flight range and time due to battery capacity limitations. One way to overcome these limitations is to harvest energy from overhead power lines. A growing body of scientific literature has ...
IEEE2022Geographically Parameterized Residential Sector Energy and Service Profile
François Maréchal, Luc Girardin, Ivan Daniel Kantor, Hür Ebuzer Bütün, Raluca-Ancuta Suciu
The large share of energy consumption in the residential sector has necessitated better understanding and evaluation of the energy needs in this sector, with the objective of identifying possible pathways for improvement. A series of approaches have been u ...
FRONTIERS MEDIA SA2019Properties of Direct-Time and Reversed-Time Transfer Functions to Locate Disturbances along Power Transmission Lines
Mario Paolone, Zhaoyang Wang, Zhe Chen
The paper discusses specific frequency-domain properties of the electromagnetic time reversal (EMTR) method applied to locate faults and, more in general, disturbances in power networks. Specifically, we investigate the properties of two transfer functions ...
IEEE2019High-Power DC–DC Converter Utilising Scott transformer Connection
Drazen Dujic, Stefan Milovanovic
To obtain a resilient and flexible DC grid, reliable means for interfacing its parts operating under different voltage levels must be ensured. This paper proposes bidirectional, isolated, DC–DC converter designed to connect either high/medium voltage bipol ...
2019Calculation of High-Frequency Electromagnetic Field Coupling to Overhead Transmission Line Above a Lossy Ground and Terminated With a Nonlinear Load
High-frequency electromagnetic fields such as those associated with electromagnetic pulse (EMP) and intentional electromagnetic interference (IEMI) can couple to overhead power lines. Since the height of the overhead power lines can be comparable or even l ...
