Analytical Computation of the Sensitivity Coefficients in Hybrid AC/DC Networks
Mario Paolone, Willem Lambrichts
In this paper, we present a model for the analytical computation of the power flow sensitivity coefficients (SCs) for hybrid AC/DC networks. The SCs are defined as the partial derivates of the nodal voltages with respect to the active and reactive power in ...
2024Unified Harmonic Power-Flow and Stability Analysis of Power Grids with Converter-Interfaced Distributed Energy Resources
Modern power distribution systems are experiencing a large-scale integration of Converter-Interfaced Distributed Energy Resources (CIDERs). Their presence complicates the analysis and mitigation of harmonics, whose creation and propagation may be amplified ...
EPFL2024Harmonic Power-Flow Study of Hybrid AC/DC Grids with Converter-Interfaced Distributed Energy Resources
Mario Paolone, Yihui Zuo, Andreas Martin Kettner, Johanna Kristin Maria Becker
As the share of Converter-Interfaced Distributed Energy Resources (CIDERs) in power distribution systems increases, hybrid AC/DC distribution systems are drawing more interest. Indeed, CIDERs usually rely on DC power and hybrid AC/DC grids with few Network ...
IEEE2023Dynamics 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 ...
2023DC 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 Verlag2023Multiobjective Vector Modulation for Improved Control of NPC-Based Multi-Source Inverters in Hybrid Traction Systems
The concept of a multi-source inverter (MSI) based on NPC topology was recently introduced for hybrid-electric powertrains to connect several dc sources to the traction load in a single conversion stage without magnetics. This work proposes a new modulatio ...
2022Distributed Scheme for Line Overload Mitigation With Linearized AC Power Flow
The transmission overload after a disturbance poses significant security risk to the power system. Once it happens, an efficient remedial action must be taken to relieve the line overloads as quickly as possible. The line overload mitigation problem become ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Experimental Validation of the Real-Time Control of an Electric-Vehicle Charging Station
Jean-Yves Le Boudec, Mario Paolone, Sherif Alaa Salaheldin Fahmy, Roman Rudnik
The high penetration of electric vehicles (EVs) charging stations (CSs), together with the progressive availability of distributed energy resources, increases the risk of grid overloading and power-quality degradation. Real-time control has been advocated ...
IEEE2021Smooth Power Direction Transition of a Bidirectional LLC Resonant Converter for DC Transformer Applications
The bidirectional LLC resonant converter operated at fixed switching frequency is a preferable candidate for a true dc transformer that does not actively control the power flow. This is due to its naturally stiff voltage ratio regardless of the imposed loa ...
2020Service Restoration Strategy in Active Distribution Networks
In the last decade, the massive penetration of Distributed Generators (DGs) has brought significant technical challenges to all the aspects related to the planning and operation of distribution networks. Thus, smart grid concept has evolved as a new operat ...
