SuperGrid Institute’s project selected for Grid2030
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.
Design of a 1200 V, 100 kW Power Converter: How Good are the Design and Modelling Tools?
During the design of power converter, design mistakes must be avoided, especially for high voltage and high power converters. Simulation tools can be used to help the designers and limit the risks. This presentation will present a design flow approach used to design and validate a 1.2 kV – 100 kW DC-DC converter which was design from die to converter levels and started for a “blank page”. The presentation is organized in four parts. Firstly, the context of the work is introduced. Then, the simulation flow approach used to validate the design is presented. For this part, the presentation will focus on the system level simulation of one inverter, including the power modules. This part will highlight the main limitations of the current simulation tools found by the designers. In the third part, an enhanced approach is proposed to overcome the limitations and the first results are presented Finally, a conclusion will be presented.

Study of Turn-to-Turn Electrical Breakdown for Superconducting Fault Current Limiter Applications
The rational insulation design of a resistive superconducting fault current limiter (r-SCFCL) requires data gathered from experimental setups representative of the final apparatus. Therefore, an experimental study was performed to characterize the electrical breakdown (BD) of liquid nitrogen (LN2) in the peculiar conditions of a quenching superconducting device.
Arc appearance and cathode spot distribution in a long gap high-current vacuum arc controlled by an external axial magnetic field
An experimental study of a high-current vacuum arc (VA) generated between two static CuCr25 contacts spaced 20 or 30 mm apart was conducted to characterize the arc appearance and the cathode spot (CS) distribution.

HVDC protection criteria for transient stability of AC systems with embedded HVDC links
The objective of this study is to propose a methodology for the transient stability assessment of a simple but representative AC grid in case of DC fault. After validation of the methodology, some HVDC link protection criteria are defined in terms of the Critical Time to Return to Operation. These criteria will be helpful for the design of HVDC protection systems or for the sizing of future HVDC links in order to respect the constraints of the existing protection strategies.
SuperGrid Institute committed to the Fête de la Science 2018
An exciting week at SuperGrid Institute with the Fête de la Science 2018! After the open house visits on Saturday the 6th of October, we welcomed students from three high school classes over the following week.
