  2. 1. Exploring the future low-carbon electricity system: impacts of nuclear power and demand patterns

    Author : Xiaoming Kan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; net system cost; electricity supply mix; Low-carbon electricity system; variable renewable energy; nuclear power; electricity system cost; demand pattern; energy system modeling;

    Abstract : To achieve the climate goals set by the Paris Agreement, the global electricity system is expected to transition towards a low-carbon electricity system. The future low-carbon electricity system is uncertain regarding both generation and demand. READ MORE

  4. 2. Stability of power systems with large amounts of distributed generation

    Author : Valerijs Knazkins; Lennart Söder; Ian A. Hiskens; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; engineering; electronics and electrical engineering; system science; Elektroteknik; Electrical engineering; Elektroteknik;

    Abstract : This four-part dissertation is essentially concerned with some theoretical aspects of the stability studies of power systems with large penetration levels of distributed generation. In particular, in Parts I and II the main emphasis is placed upon the transient rotor angle and voltage stability. READ MORE

  5. 3. Energy systems studied of biogas : Generation aspects of renewable vehicle fuels in the transport system

    Author : Mimmi Magnusson; Per Alvfors; Umberto Desideri; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; biogas; biomass; energy system; first-generation biofuels; renewable vehicle fuels; second-generation biofuels; supply- and demand-side measures; third-generation biofuels; transport system;

    Abstract : The transport sector is seen as particularly problematic when concerns about climate change and dependency on fossil energy are discussed. Because of this, bioenergy is strongly promoted for use in the transport sector, both on a European level and nationally in Sweden. READ MORE

  6. 4. System-Level Analysis and Design under Uncertainty

    Author : Ivan Ukhov; Zebo Peng; Petru Ion Eles; Jian-Jia Chen; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : One major problem for the designer of electronic systems is the presence of uncertainty, which is due to phenomena such as process and workload variation. Very often, uncertainty is inherent and inevitable. If ignored, it can lead to degradation of the quality of service in the best case and to severe faults or burnt silicon in the worst case.

  7. 5. Selection of Decentralized Control Configuration for Uncertain Systems

    Author : Ali Kadhim; Wolfgang Birk; Thomas Gustafsson; Miguel Castaño Arranz; Torsten Wik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Abstract : Industrial processes nowadays involve hundreds or more of variables to be maintained within predefined ranges to achieve the production demands. However, the lack of accurate models and practical tools to design controllers for such large processes motivate the engineers/practitioners to break the processes down into smaller subsystems and applying decentralized controllers.
