Recherche & collaboration
Qu’est-ce qui nous rend unique ?
SuperGrid Institute doit son succès aux personnes qui composent nos différents départements de recherche. Nos équipes viennent d’horizons divers, tant industriels qu’universitaires, et la richesse de leur expérience et de leurs compétences rend l’Institut unique.
Chaque personne apporte une expertise spécifique et ce vivier de connaissances offre aux spécialistes de différents domaines la possibilité de collaborer sur des solutions innovantes pour résoudre des problèmes techniques.
L’Institut bénéficie d’étroites relations de collaboration avec des acteurs de l’industrie et des institutions académiques. Alors que les forces complémentaires de nos partenaires apportent des éclairages et des approches innovantes aux défis techniques, nous développons nos départements de recherche en toute indépendance. Des investissements conjoints publics-privés et des projets de collaboration financent le travail.
Les installations de recherche, les plateformes de test et les laboratoires de pointe de SuperGrid Institute sur les sites de Villeurbanne et de Grenoble sont la clé du succès de nos départements de recherche.

A Comparative Assessment of […] for Modular Multilevel Converter
Thanks to scalability, performance and efficiency, the Modular Multilevel Converter (MMC), since its invention, becomes an attractive topology in industrial applications such as high voltage direct current (HVDC) transmission system.
A Novel Modular Multilevel Converter Modelling Technique Based on Semi-Analytical Models
In this work, a novel dynamic models for MMC is proposed. The proposed models are intended to simplify modeling challenges related to the high number of switching elements in the MMC. The models can be easily used to simulate the converter for stability analysis or protection algorithms for HVDC grids.
Full-selective protection strategy for MTDC grids […] DC circuit breakers
A novel protection strategy for multi-terminal high voltage direct current (HVDC) grids based on the implementation of breaking modules (BM) with both limiting and breaking capabilities will be presented. It incorporates a resistive-type superconducting fault current limiter (SFCL) in series with a mechanical DC circuit breaker (DCCB). The proposed arrangement of BMs allows an intrinsic selective fault identification criteria based on the quenching of the SFCL. The fault current limitation reduces the breaking capability, speed and energy requirements for the DCCB. Furthermore, a continuous grid operation can be assured by adding DC inductors and capacitors, assuring a constant power flow during and after the fault event. In this paper, a primary protection scheme is conceptually described and off-line simulation studies performed in EMTP-RV® are discussed.
