2. 21. Overlay Multicast Networks : Elements, Architectures and Performance

   Author : Doru Constantinescu; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Today, the telecommunication industry is undergoing two important developments with implications on future architectural solutions. These are the irreversible move towards Internet Protocol (IP)-based networking and the deployment of broadband access. READ MORE

4. 22. Synchrophasor based Steady State Model Synthesis of Active Distribution Networks

   Author : Farhan Mahmood; Luigi Vanfretti; Francisco Gonzalez-Longatt; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active distribution networks; phasor measurement units; model synthesis; real-time simulation; hardware-in-the-loop.; Electrical Engineering; Elektro- och systemteknik;

   Abstract : With the increased penetration of distributed energy resources (DERs) at lower voltage levels, distribution networks (DNs) are being transformed into active grids. This has led to a paradigm shift in the operation, planning and control of DNs. READ MORE

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Abstract : In recent decades, communication networks have had a profound effect on society. Wireless communication has affected our lifestyle and altered how humans communicate and the Internet has revolutionized how we access, publish and disseminate information. READ MORE

6. 24. Opportunistic Content Distribution : A System Design Approach

   Author : Sylvia Todorova Kouyoumdjieva; Gunnar Karlsson; Martin May; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The penetration of smart pocket-size devices that provide constant Internet connectivity, such as mobile phones, has significantly changed the way people obtain, view and share information. Content provision is not anymore a prerogative to professionals; individuals are not solely customers, but also act as content generators and distributors. READ MORE

7. 25. Fault location in resonant earthed medium voltage distribution systems

   Author : Md Zakaria Habib; Nathaniel Taylor; Mohamed F. Abdelfattah; Matti Lehtonen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical distribution; Distribution network; Reliability; SAIDI; Fault location; FL; Fault passage indicator; FPI; Compensated neutral; Resonant earthing; Resonant grounding; Petersen coil; Arc suppression coil.; Distributionsnät; Tillförlitlighet; Fellokalisering; FL; Felpassageindikation; FPI; Kompenserat nät; Spoljordat nät; Petersenspole.; Electrical Engineering; Elektro- och systemteknik;

   Abstract : A major challenge in electric distribution systems is to increase the reliability of the electricity supply in an economical way. At the final medium-voltage level in the system, such as 10 kV or 20 kV, a single feeder may supply tens of medium/low-voltage transformers and hundreds of customers, with many branches of lines and cables where faults can occur.
