Partial discharge localization in power transformer tanks using machine learning methods
Marcos Rubinstein, Hamidreza Karami
This paper presents a comparison of machine learning (ML) methods used for three-dimensional localization of partial discharges (PD) in a power transformer tank. The study examines ML and deep learning (DL) methods, ranging from support vector machines (SV ...
2024Dynamics 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 ...

Mario Paolone, Rahul Kumar Gupta, Sherif Alaa Salaheldin Fahmy
This work presents an optimization framework to aggregate the power and energy flexibilities in an interconnected power distribution systems. The aggregation framework is used to compute the day-ahead dispatch plans of multiple and interconnected distribut ...
2022A VSC-Based BESS Model for Multi-Objective OPF Using Mixed Integer SOCP
This paper presents a new model of voltage source converter (VSC)-based battery energy storage systems (BESSs) that interface with power grids. A VSC-based BESS is made up of a series connection of a VSC, its connecting transformer and a BESS. The VSC allo ...
IEEE2020Partial Discharge Localization Using Electromagnetic Time Reversal: A Performance Analysis
Marcos Rubinstein, Mohammad Azadifar, Hamidreza Karami, Zhaoyang Wang, Ali Ghasemi
In this study, first, a comparison on the application of electromagnetic time reversal (EMTR) and time difference of arrival (TDoA) in partial discharge localization in power transformers is presented. A two-dimensional finite-difference time-domain simula ...
2020Enhanced DAB for Efficiency Preservation using Adjustable-Tap High-Frequency Transformer
Elison de Nazareth Matioli, Armin Jafari, Furkan Karakaya
Efficient DC-DC power-conversion with wide-span voltage-regulation is crucial to a sustainable and robust power electronics system. Dual-active-bridge (DAB) offers straight-forward regulation and its transformer enables voltage step-up/down required for ma ...
2019Minimum Energy Point in Constant Frequency Designs under Adaptive Supply Voltage and Body Bias Adjustment in 55 nm DDC
Andreas Peter Burg, David Ruffieux
In this paper, we describe a systematic low-power design methodology for technologies that offer a strong body factor. Specifically, we explore both the body bias voltage and the supply voltage knobs in order to find the MEP (minimum energy point) for a co ...
IEEE2019Galvanically 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 ...
