The renewables integration via HVDC grids

2021-08-11T17:55:30+02:00October 24th, 2019|Architecture & systèmes du supergrid|

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.

Phd Guilherme DANTAS DE FREITAS “Development of a methodology for DC grid protection strategies comparison”

2021-08-11T17:42:24+02:00October 18th, 2019|Architecture & systèmes du supergrid, Phd|

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....

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

2023-01-31T13:33:14+01:00October 10th, 2019|Architecture & systèmes du supergrid, 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”.

Use of Unbalanced Insulation for the Limitation of Double-Pole Lightning Flashovers in Double Circuit HVDC Overhead Lines

2023-01-31T13:32:29+01:00October 7th, 2019|Tout|

Lightning studies are a critical part of any system involving overhead lines. As HVDC technologies develop, new problems and questions arise regarding the lightning performance of HVDC overhead lines. For instance, the installation of two separate HVDC circuits on the same transmission tower may become a popular alternative for the uprating of old AC lines to take advantage of the already existing Right-of-Ways. Double-pole flashovers may be particularly constraining in double circuit HVDC systems, since they could lead to the loss of both circuits at the same time due to the flashover of both poles of the same polarity having the same amplitude at all times (which is not the most likely case in AC systems). This corresponds to a 100% of loss of transmitted power, which could represent a threat for the system stability. This constitutes the main motivation for this work.
