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.

Possibilities and requirements on operation of future MVDC networks
Possibilities and requirements on operation of future MVDC networks Abstract After high voltage direct current (HVDC) has gained momentum, the same challenges, as the shift to distributed architecture with high renewables integration, are now causing medium voltage direct current (MVDC) to arise for distribution system. Several pilot projects are emerging worldwide to shed to light the advantages of MVDC technology. These networks are typically deployed on a dedicated area with selected composition of loads and sources under limited power. They have a configuration of a so-called soft link, being connection between two medium voltage alternative current (MVAC) networks and having a couple of MVDC nodes with loads and generations. This paper focuses on different MVDC configurations for a representative suburban distribution grid. The goal is to find a technically and economically viable configuration (s) and evaluate the interest of DC technology. A technical economic assessment (TEA) is performed among three networks configurations (full AC, full DC and hybrid MVAC+LVDC) considering qualitative and quantitative key performance indicators (KPI) including converter design, control and protection [...]
Evaluation of the interference effects of HVDC fault on a buried pipeline
Evaluation of the interference effects of HVDC fault on a buried pipeline Abstract HVDC transmission systems have potential effects on buried pipelines in their vicinity. Thereby, significant interferences can arise when a fault occurs on an HVDC overhead line, depending on factors such as the distance between the line and the pipeline, the exposure length, the soil resistivity, and the line configuration. This paper investigates the effects of these parameters on the pipeline’s induced transient overvoltage. Under normal operating conditions, only small current variations occur in the poles, and their electromagnetic field effects are negligible. However, when a pole-to-ground fault occurs, a transient stage lasting a few milliseconds leads to a significant increase in the electromagnetic field. This paper presents a variety of simulation studies obtained using an electromagnetic transients software (EMTP). Simulations were conducted for different HVDC configurations, specifically symmetric monopolar and bipolar setups. The results show that the induced voltage is significantly higher in bipolar configuration, but in both cases, the effects are not negligible. Precautions must be taken to mitigate [...]
