1. 6. Flexibility from local resources: Congestion management in distribution grids and carbon emission reductions

   Författare :Nima Mirzaei Alavijeh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexibility; local energy system; local flexibility market; emission abatement strate- gies; congestion management; distribution system operator;

   Sammanfattning : Flexibility from local energy systems has been discussed as a facilitator for the transition towards a more carbon-neutral energy system. Two use cases of this flexibility are congestion management in electricity distribution networks, and an individual-driven reduction of carbon footprints. LÄS MER

3. 7. Operation, Monitoring, and Protection of Future Power Systems: Advanced Congestion Forecast and Dynamic State Estimation Applications

4. 8. Reliability in performance-based regulation

   Författare :Torbjörn Solver; Lennart Söder; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Performance-Based Regulation; Distribution System; Power System Reliability; Monte Carlo Simulations; Quality of Supply; Electric power engineering; Elkraftteknik;

   Sammanfattning : In reregulated and restructured electricity markets the production and retail of electricity is conducted on competitive markets, the transmission and distribution on the other hand can be considered as natural monopolies. The financial regulation of Distribution System Operators (DSOs) has in many countries, partly as a consequence of the restructuring in ownership, gone through a major switch in regulatory policy.

5. 9. Asymptotics of Eigenpolynomials of Exactly-Solvable Operators

   Författare :Tanja Bergkvist; Boris Shapiro; Andrei Martinez-Finkelshtein; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; exactly-solvable; eigenpolynomials; zero distribution; asymptotics; MATHEMATICS; MATEMATIK; matematik; Mathematics;

   Sammanfattning : The main topic of this doctoral thesis is asymptotic properties of zeros in polynomial families arising as eigenfunctions to exactly-solvable differential operators. The study was initially inspired by a number of striking results from computer experiments performed by G. Masson and B. Shapiro for a more restrictive class of operators. LÄS MER

7. 10. Security in Physical Distribution Networks - A Survey Study of Swedish Transport Operators

   Författare :Luca Urciuoli; Teknisk logistik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antagonistic threats.; supply chain security; cargo security; physical distribution security; transportation security; cargo theft; Quantitative Risk Assessment;

   Sammanfattning : The objective of this study is to understand what factors influence the security of physical distribution networks. Thereafter it aims to bring to light what security measures exist today to enhance security and finally how to determine the profitability of security investments. LÄS MER
