  2. 21. Demand Flexibility for the Simultaneous Provision of Multiple Services : Tapping the Potential of Controllable Electric Loads for Frequency Reserves and Energy Arbitrage

    Author : Lars Herre; Lennart Söder; Qiuwei Wu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aggregator; chance constrained optimisation; demand response; de-mand response provider; demand side management; frequency reserves; load control; stochastic optimization; aggregator; riskbegränsad optimering; efterfrågestyrning; leverantör av efterfrågesvar; efterfrågeflexibilitet; frekvensreserver; laststyrning; stokastisk optimering.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Power systems with increasing shares of renewable energy sources require sufficient flexibility sources. One source of flexibility for future power systems is constituted by flexible electric loads. The concept of demand response captures the utilization of demand side flexibility to provide services to the power system. READ MORE

  4. 22. Plasticity of salamander skeletal muscle cells

    Author : Paula Borg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Regeneration is unevenly spread throughout the animal kingdom. Some of the invertebrates have a very high regenerative capacity but the capacity to replace lost or damaged tissues in mammals is limited. READ MORE

  5. 23. Social inhibition and socioemotional functioning in middle childhood

    Author : Kerstin Bengtsgård; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Social Inhibition Overfriendliness; Dysregulation; Socioemotional Functioning; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : Social inhibition, or in lay language "shyness", means a tendency to react with fearful and hesitant behaviors innovel social encounters. Lowinhibition, on the other hand is associated with a capacity to easily approachnovel social situations. However, low-inhibition might co-occur with difficulties in inhabiting undesired socialbehaviors. READ MORE

  6. 24. Ring network design in telecommunications : optimization based solution approaches

    Author : Mathias Henningsson; Jens Clausen; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : When designing a telecommunication network, one often wish to include some kind of survivability requirement, for example that the network should be two-connected. A two-connected network fulfills the requirement that there should be at least two paths with no links in common between all pairs of nodes. READ MORE

  7. 25. Optimization modeling of frequency reserves and inertia in the transition to a climate-neutral electricity system

    Author : Jonathan Ullmark; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; generation expansion planning; frequency reserves; inertia; Energy system modeling; synthetic inertia; frequency control;

    Abstract : The ongoing transition towards electricity production systems that are dominated by wind and solar power challenge both the traditional strategy for meeting a varying electricity demand and the traditional way of controlling the AC frequency of the electricity grid. This work investigates how frequency reserves (FR) and inertia, as well as inter-hourly variation management interact in the transition to a climate-neutral electricity system. READ MORE
