As part of its research, SuperGrid Institute studies the phenomena of partial discharge under DC voltage. Environmental issues emphasised in the European project PROMOTioN encourage the exploration for possible replacement of SF6 gas and remains a strong component of the study at SuperGrid Institute.

The renewables integration via HVDC grids

The large-scale integration of renewable electricity generation poses both structural, economic and management challenges. Among the major challenges, one can note the grid integration and the routing of this energy from the production units to the consumption poles. Major issues have to be faced like insufficient transmission capability, inertia reduction, stability margins mitigation. The HVDC is not a new idea but it can provide some interesting answers to these challenges. The keynote will list the locks and how they can be addressed by the HVDC grid. Finally, the underlying scientific issues will be discussed.

High Voltage Direct Current (HVDC) grids are considered a promising solution for problems faced by nowadays power system such as: lines congestion, integration of large amounts of renewable power and enhancement of AC system stability. Among the challenges in the deployment of a HVDC meshed grid, the protection of these grids is regarded as one of the most critical. The protection of HVDC grid is challenging not only because the swift transients and fault currents without zero-crossing, but also due to the impact a DC faults can have on the AC system. Several propositions for HVDC grids protection strategies can be found in literature....

SuperGrid Institute at “Fête de la Science”: come and discover the electricity network of tomorrow

2019-10-11T15:37:45+02:00octobre 10th, 2019|Evenement|

The thinking caps are on this week at SuperGrid Institute with the “Fête de la Science” event! Over the last few days the institute has welcomed four classes of high school students who learnt about the work that we do through fun, interactive activities. This Saturday afternoon, we are opening our doors to the public to round of the week in style! Come along and see us!

Ahmed Zama honored with the IEEE “Doctorate Laureate” for his thesis work

2019-10-11T14:56:18+02:00octobre 10th, 2019|Evenement|

Every year the French chapter of IEEE Power & Energy Society (PES), in collaboration with SEE (Society of Electricity, Electronics and Information and Communication Technologies), recognises outstanding PhD theses and hands out the “outstanding engineer of the year” prize at an annual evening ceremony. This Wednesday the 9th of October, Ahmed Zama was honoured with the IEEE “Doctorate Award” for his thesis work on “Modeling and Control of Modular Multilevel Converters (MMCs) for HVDC applications”.
