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.
Optimal sizing of a power electronic traction transformer for railway applications
This paper presents a methodology to optimize the sizing of such power converters in order to compare different topologies for a given application. The proposed procedure maximises the efficiency of the converter under a limited volume.

Uncertainty Quantification for the Eulerian-Lagrangian simulation of evaporating sprays
Evaporating sprays can be almost routinely simulated using an Eulerian-Lagrangian approach which relies on a RANS modeling of the continuous phase and a Lagrangian description of the discrete phase, including a turbulent dispersion model to express the effect of turbulent fluctuations within the carrier phase on the spray particles and an evaporation model for the spray droplets.
