An Overview on the Reliability of Modern Power Electronic Based Power Systems

Renewable energy resources are becoming the dominating element in power systems. Along with de-carbonization, they transform power systems into a more distributed, autonomous, bottom-up style one. We speak of Smart Grid and Microgrid when distributed energy resources take over. While being a means to improve technical and financial efficiency,...

Future energy systems and the protection of the electrical grid

One of the main research topics inside this thesis will be on what the effect will be on the present protection scheme when distributed generation units are extensively implemented inside the distribution system. The application of distributed generation will have an impact on the present protection scheme. This because the distributed...

Novel Topology of Saturated-core Fault Current Limiter

Increasing levels of fault currents in utility grids are expected to result in mechanical and thermal overstresses of different power system components. To cope with these increased levels, expensive upgrades and replacements of currently employed Circuit Breakers might be required in the near future. Fault Current Limiters (FCLs) are expected...
