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.

Design of a single branch of energy storage submodules con-nected to HVDC systems to support AC grids
Design of a single branch of energy storage submodules con-nected to HVDC systems to support AC grids Abstract The number of HVDC installations is increasing and the decarbonization of power systems makes it necessary to install storage systems. It might become relevant to assess the synergies between both trends by connecting storage systems on the DC side of HVDC systems. The contribution of this paper is to show the feasibility and the design of such a system to provide three different ancillary services: power oscillation damping (POD), fast frequency response (FFR), or wind power oscillation smoothing. The DC storage system consists of a series connection of sub-modules with energy storage devices connected to each sub-module through a DC-DC converter. For the proposed designed methodology, a first simple average model of the DC storage converter is developed to run preliminary EMT simulations to obtain power profiles for the energy storage elements according to the system needs. These profiles are used as inputs for designing the storage system. The design methodology is validated by performing [...]
CO2 Footprint of Medium Voltage DC Solid State Transformer
Power converters are essential for renewable energy integration, and this study uses Life Cycle Assessment to evaluate the environmental impact of a DC Solid State Transformer. The use phase generates the most emissions, which will decrease as electricity decarbonizes. An optimal operating frequency is identified by factoring in carbon tax, with future economic costs of emissions expected to rise.
Methodology to define the arm inductance range in a Modular Multilevel Converter station for HVDC applications based on steady-state and DC pole-to-pole fault
This paper proposes a methodology to define the arm inductance range in modular multilevel converters (MMC) for HVDC applications, considering both steady-state performance and DC pole-to-pole faults. It includes a sensitivity analysis and simplified MMC model for calculating fault currents.
