  2. 1. Reliability in performance-based regulation

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

    Abstract : 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.

  4. 2. Modelling Ion Cyclotron Resonance Heating and Fast Wave Current Drive in Tokamaks

    Author : Abdul Hannan; Torbjörn Hellsten; Dirk van Eester; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermonuclear fusion; Tokamak; DIII-D; JET; ITER; DEMO; ICRF; ICRH; Fast magnetosonic waves; TTMP; ELD; ICRH; Thermonuclear;

    Abstract : Fast magnetosonic waves in the ion cyclotron range of frequencies have the potential to heat plasma and drive current in a thermonuclear fusion reactor. A code, SELFO-light, has been developed to study the physics of ion cyclotron resonantheating and current drive in thermonuclear fusion reactors. READ MORE

  5. 3. Mean-Variance Portfolio Optimization : Eigendecomposition-Based Methods

    Author : Fred Mayambala; Torbjörn Larsson; Elina Rönnberg; Juma Kasozi; Ann-Brith Strömberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Modern portfolio theory is about determining how to distribute capital among available securities such that, for a given level of risk, the expected return is maximized, or for a given level of return, the associated risk is minimized. In the pioneering work of Markowitz in 1952, variance was used as a measure of risk, which gave rise to the wellknown mean-variance portfolio optimization model. READ MORE

  6. 4. Numerical solution of quasilinear kinetic diffusion equations in toroidal plasmas

    Author : Lars Josef Höök; Torbjörn Hellsten; Thomas Johnson; Jukka Heikkinen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : One of the main challenges for the realization of a working fusion power plant is an increased detailed understanding of kinetic phenomena in toroidal plasmas. The tokamak is a toroidal, magnetically confined plasma device and is currently the main line towards a power plant. READ MORE
