AC Grid Forming by Coordinated Control of Offshore Wind Farm connected to Diode Rectifier based HVDC Link-Review and Assessment of Solutions
This paper reviews a few of the major control solutions for AC grid forming and operation of DR-HVDC based OWFs. Then these solutions are compared based on their approach in solving the major challenges involved.
PhD Etienne OUSS “Characterization of Partial Discharges and Defect Identification in High-Voltage Direct Current GIS”
This thesis aimed to characterize partial discharges in DC gas-insulated substations, and to develop an automatic defect identification tool. The first step of this work was the development of a partial discharge measuring bench. The complete study has been performed in a GIS section, so that the results can be directly applied to industrial equipment.

Models of AC and DC cable systems for technical and economic evaluation of offshore wind farm connection
Accurate cable modeling is a recurrent issue for electric architecture evaluation and design, especially in specific contexts, like offshore wind farms. This paper proposes optimal analytical cable models for the technical and economic assessment of offshore wind generation systems.
Space Charge Measurements for HVDC GIS Spacer using the Thermal Step Method
High voltage direct current (HVDC) technologies are currently emerging to develop new energy transmission networks able to integrate renewable energy sources with remote locations from consumers. Gas Insulated Substations (GIS) have been widely used in alternating current (AC) transmission due to their low footprint and high reliability.
Breakdown Characteristics and Pre-Breakdown Phenomena in Liquid and Boiling Nitrogen with Tape Electrode for r-SCFCL Applications
The rational insulation design of a resistive superconducting fault current limiter (r-SCFCL) requires data gathered from experimental setups relevant for the final apparatus.
A 100 kW 1.2 kV 20 kHz DC-DC converter prototype based on the Dual Active Bridge topology
This article presents the design, the fabrication, and the test of an isolated DC-DC converter for renewable energy applications. The converter is based on the Dual Active Bridge topology and uses silicon carbide power semiconductors and a medium frequency transformer. The design process covers hardware ranging from the semiconductor die to the complete power converter. For the control, a rapid prototyping approach was used. The experimental validation of the 100 kW prototype is presented.
