Galvanically Isolated Modular Converter

Alexandre François Christe

The ever increasing penetration of renewable energy systems in the distribution grids will inevitably require profound changes in the grid infrastructure. One emerging direction, the medium voltage dc (MVdc) grids, is the cornerstone of this work. They are ...

Voltage Control in Active Distribution Networks Under Uncertainty in the System Model: A Robust Optimization Approach

Mario Paolone, Konstantina Christakou

Within the context of ancillary services for Active Distribution Networks (ADNs), application of intelligent control techniques is required in order to achieve specific operation objectives. Despite their differences, most control mechanisms proposed in th ...

The key impact of incorporated Al2O3 barrier layer on W-based ReRAM switching performance

Yusuf Leblebici, Jury Sandrini, Elmira Shahrabi, Cecilia Giovinazzo

In this article, we inspected the bipolar resistive switching behavior of W-based ReRAMs, using HfO2 as switching layer. We have shown that the switching properties can be significantly enhanced by incorporating an Al2O3 layer as a barrier layer. It stabil ...

Locating lightning strikes and flashovers along overhead power transmission lines using electromagnetic time reversal

Mario Paolone, Gianluca Antonini, Reza Razzaghi, Keyhan Sheshyekani

The paper presents a method to identify the location of direct lightning strikes to overhead transmission lines and potential subsequent flashover(s). The method is based on the electromagnetic time reversal theory and relies on the use of a single measure ...

Insulation effect on thermal stability of Coated Conductors wires in liquid nitrogen

Bertrand Dutoit, Bertrand Dutoit

Superconducting wires are not perfectly homogeneous in term of critical current as well as stabilization. In resistive fault current limiter applications this could lead to hot spots if the fault current is only slightly above the nominal current of the de ...

Study and characterization of soft magnetic materials for beam intensity monitors at CERN

Heinrich Hofmann, Silvia Aguilera Murciano

At CERN, the circulating beam current measurement is provided by two types of transformers, the DC Current Transformer (DCCT) and the Fast Beam Current Transformer (FBCT). Each transformer is built based on toroidal cores made from a magnetic material. Dep ...

Can Resistive-Type Fault Current Limiter Operate in Cryogen-Free Environment?

Bertrand Dutoit, Bertrand Dutoit

Superconducting fault current limiters are unique devices that offer fast response to fault without need of an external triggering system. Therefore, they are interesting for industrial use, although their price is high. The principle of the resistive faul ...
