  1. 1. Towards Intelligent Power-System Monitoring: Segmentation, Feature Extraction, and Identification of Underlying Causes

    Författare :Cuong Le; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; harmonics analysis; Power-system monitoring; segmentation; power-system measurement; power quality; event analysis; signal-processing applications;

    Sammanfattning : The increase in size of modern power systems together with the concept smart grid requires advanced monitoring to ensure system availability, reliability, and power quality. The huge amount of available data no longer permits analysis to be implemented manually and centrally. LÄS MER

  3. 2. Global energy transitions : Renewable energy technology and non-renewable resources

    Författare :Simon Davidsson; Mikael Höök; Kjell Aleklett; Björn Sandén; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy transitions; natural resources; renewable energy; sustainable development; growth curves; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Sammanfattning : The global energy system is dominated by the use of fossil fuels. This system suffers from several problems, such as different environmental issues, while the long-term energy security is sometimes questioned. LÄS MER

  4. 3. An agent-based approach to supply side modeling of agricultural and power systems

    Författare :Emma Jonson; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power system transitions; Agent-based modeling; agricultural land-use; Cobweb model; stability; non-equilibrium; price fluctuations; market interaction;

    Sammanfattning : This thesis deals with the modeling of economic systems in the context of agricultural and power systems, and some aspects of the difference between the standard economics equilibrium approach and the agent-based approach. We model the supply side, where agents make decisions on what to produce or in what to invest. LÄS MER

  5. 4. The social power grid : The role of institutions for decentralizing the electricity grid

    Författare :Martin Warneryd; Eva Thorin; Tomas Kåberger; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik; Reesbe företagsforskarskola;

    Sammanfattning : The world’s existing electricity grids face several challenges if they are to continue to provide a stable supply in the future. Aging electricity grids and the massive implementation of renewable sources require a different flexibility and robustness of future grids. LÄS MER

  7. 5. Utilization of local bioresources for transport fuels - System analysis for decision support

    Författare :Muhammad Arfan; Ola Eriksson; Jonas Ammenberg; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System analysis; local bioresources; transportation fuels; LCA; LCC; geography of transitions; Systemanalys; Lokala resurser; drivmedel; LCA; LCC; geografi och om-ställning;

    Sammanfattning : This thesis presents a comprehensive system analysis of the utilization of biowaste and forest industry residues to produce transportation fuels. It explores various aspects such as the constraints to the production system’s value chain development, the utilization of the geographical proximity of biofuel technology innovation system components, environmental impacts, and economic costs.
