Nearly 150 people gathered together on Monday the 8th of April to inaugurate SuperGrid Institute’s headquarters. Our HQ is 5,560 square meters of offices and platforms dedicated to developing technologies: to build the electricity transmission network of the future, and to participate in the wide-scale integration renewable energies within the power network.
SuperGrid Institute has been rewarded for its ambitious intellectual property strategy, ranking first of the top 10 patent applicants in the SME category for 2018. Created in 2014, SuperGrid Institute has already filed 50 patent applications, including 16 in 2018 alone.
PhD Loriane DESMARS « Study of electrical and thermal properties of epoxy-anhydride composite materials for high voltage insulation »
The work presented in this manuscript has been motivated by the necessity to develop more efficient electrical insulating materials compared to commercially available ones. An epoxy-anhydride matrix filled with micron sized alumina, often used to produce GIS solid insulators, has been used as a reference for this study.
The main objective of this thesis is to develop a methodology to size PETT topologies, in order to compare them.
PhD Amjad MOUHAIDALI « Contribution to the modelling of HVDC cables for electromagnetic transient simulations »
The integration of new technologies in the electric grids made them more and more complex, and most likely future growth of power grids will be based more on underground cables than overhead lines. One problem here, is that the mathematical model for electromagnetic simulation of power cables still has some shortcomings regarding stability, accuracy and passivity. In this thesis, we evaluate the cable parameters using analytical and numerical methods.
PhD Juan-Carlos GONZALEZ « Transient stability of high voltage AC-DC electric transmission systems »
This thesis addresses the transient stability analysis of hybrid AC/DC electric transmission systems. More precisely two questions sought to be investigated: What is the impact of a DC contingency on AC transient stability? How can we take advantage of the DC transmission systems as control inputs in order to enhance AC transient stability?
SuperGrid Institute is delighted to have signed a framework agreement with the CNAM (Conservatoire National des Arts et Métiers) regarding training and in particular around supergrid and HVDC technologies. This agreement covers lifelong learning, technology research and the provision for scientific and technical proficiency.
PhD Quentin MOLIN « High Voltage SiC MOSFET Robustness study: threshold voltage shift and short-circuit behaviour »
This manuscript is a contribution to reliability and robustness study of MOSFET components on silicon carbide “SiC”, wide band gap semiconductor with better characteristics compared to silicon “Si” material. Those new power switches can provide better switching frequencies or voltage withstanding for example in power converter. SiC MOSFET are the results of approximately 10 years of research and development and can provide increased performances and weight to some converter topology for high voltage direct current networks.
SuperGrid Institute and IMDEA joint forces with the support of REE, and created a consortium. This consortium was selected from more than 80 projects. Through the "Reduced Inertia Transient Stability Enhancement" (RITSE) project, SuperGrid Institute will strive to improve the transient stability of the AC networks by coordinating the use of batteries and HVDC links.
This work proposes a method for the full development, from conception to implementation, of the supervisory control of a multi-terminal HVDC (MT-HVDC) system.
