2. 21. The Impact of Non-synchronous Generation on Power Systems Dynamics

   Author : Harold Chamorro; Mehrdad Ghandhari; Jonas Persson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Due to the increasing integration of Renewable Energy Sources (RES), and the installation of High Voltage Direct Current (HVDC) systems, more power is injected to the AC grid based on power electronic converters. This kind of power injection is called non-synchronous generation in this thesis. READ MORE

4. 22. Bandwidth-reduced Linear Models of Non-continuous Power System Components

   Author : Jonas Persson; Lennart Söder; Liisa Haarla; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linearization methods; frequency analysis; transient analysis; time-domain simulations; eigenvalues; linear analysis; TCSC; Electric power engineering; Elkraftteknik;

   Abstract : Denna avhandling är fokuserad på modellering av elkraftsystemkomponenter och deras representation vid simuleringar av elkraftsystem. Avhandlingen jämför olika linjäriseringstekniker. Dessa tekniker är såväl numeriska som analytiska och används vid linjärisering av ett dynamiskt system. READ MORE

5. 23. Structural investigation and lateral growth of silicon carbide crystals

   Author : Henrik Jacobson; Marek Skowronski; Linköpings universitet; []
   Keywords : ;

   Abstract : Today, most of the electronic device technology is based on Si as a semiconducting material. The demands from the industry of improved performance within smaller devices drives the silicon based devices to the limits imposed by nature and not by technology. To realize these demands new materials like silicon carbide (SiC) must be investigated. READ MORE
