2019-09-09T14:16:14+02:00September 6th, 2019|Conference, Power Electronics & Converters, Supergrid Architecture & Systems|

At the closing session, Abdelkrim Benchaib, General Chairman of EPE’20, received the EPE flag, on stage, from Mario Marchesoni, General Chairman of EPE’19, in the presence of Leo Lorenz, President of the EPE association. During this conference, Abdelkrim Benchaib was also elected as a member of the executive committee of EPE ECCE Europe for 4 more years.

Tuning of Droop Parameters Using Virtual Capacitor Control to Improve Voltage Dynamics

2019-09-02T14:59:48+02:00September 2nd, 2019|Publications, Supergrid Architecture & Systems|

This paper proposes a new approach to tuning voltage droop parameters in an MMC-based multi-terminal HVDC system. Using the new degree of freedom offered by the virtual capacitor control, the transient behavior of the DC voltage can be improved without adverse effects on the connected AC grids.

Comparaison and assessment of implementation techniques for dynamics MMC type models

2019-09-02T14:54:06+02:00September 2nd, 2019|Publications, Supergrid Architecture & Systems|

Modeling Modular Multilevel Converters requires a special attention due to the strong associations between the accuracy and the complexity of models on one hand and the accuracy and simulation speed on the other hand. This paper investigates different implementation techniques for MMC models and gives an overview about their development and rapidity.

Effect of the Surge Arrester Configuration in MMC-HVDC Systems under DC and Converter Fault Conditions

2019-06-24T10:24:43+02:00June 18th, 2019|Publications, Supergrid Architecture & Systems|

Different surge arrester configurations are studied for a modular multilevel converter (MMC) in a symmetrical monopole configuration. Each configuration is analyzed under fault conditions including DC side faults and faults inside the converter station. The configurations considered are compared in terms of overvoltages, current levels and energy dissipation.

SuperGrid Institute’s participation in PROMOTioN’s Work Package 9

2019-06-03T18:10:39+02:00May 22nd, 2019|Publications, Supergrid Architecture & Systems|

SuperGrid Institute is proud to have been an active participant in the PROMOTioN project since 2016. This project is part of the European Union’s Horizon 2020 program and is made up of several work packages (WP) that share a common aim: developing meshed HVDC offshore grids that are both cost effective and reliable, through technological innovation. SuperGrid Institute is an active member of several Work Packages, including WP9 whose objective is to develop fault clearing strategies using Hardware-in-the-Loop (HIL) real-time simulation (RTS).

SuperGrid Institute presents a brilliant innovation at CIGRE-IEC 2019 in Japan

2019-06-10T16:39:30+02:00April 24th, 2019|Conference, Supergrid Architecture & Systems|

The Energy Management Control of MMC by SuperGrid Institute was presented in Japan this week at the CIGRE-IEC 2019 Conference on EHV and UHV (AC & DC), generating stimulating discussions about this new technology.

Overview of DC–DC Converters Dedicated to HVdc Grids

2019-02-19T10:05:13+02:00February 19th, 2019|Power Electronics & Converters, Publications, Supergrid Architecture & Systems|

This paper presents an overview of the dc–dc power converters dedicated to HVdc proposing a classification based on their structure. Two large families are established: those which provide galvanic isolation, and those which do not. Several subfamilies are also proposed. An overview of the main HVdc applications that can be targeted with each family is also presented, highlighting the main converter requirements for each application case.

PhD Amjad MOUHAIDALI “Contribution to the modelling of HVDC cables for electromagnetic transient simulations”

2019-02-13T11:02:37+02:00February 13th, 2019|Phd, Supergrid Architecture & Systems|

The integration of new technologies in the electric grids made them more and more complex, and most likely future growth of power grids will be based more on underground cables than overhead lines. One problem here, is that the mathematical model for electromagnetic simulation of power cables still has some shortcomings regarding stability, accuracy and passivity. In this thesis, we evaluate the cable parameters using analytical and numerical methods.
