  1. 11. Synergy between Photovoltaic Power Generation and Electric Vehicle Charging in Urban Energy Systems : Optimization Models for Smart Charging and Vehicle-to-Grid

    Författare :Reza Fachrizal; Joakim Munkhammar; Mahmoud Shepero; Joakim Widén; Johan Driesen; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Vehicles; Photovoltaics; Smart Charging; Vehicle-to-Grid; Urban Energy Systems; Load Matching; Self-Consumption; Optimization; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Sammanfattning : Cities are responsible for around 75% of global primary energy use and 70% of global greenhouse gas (GHG) emissions, with buildings and urban mobility being two key contributors. Actions to reduce GHG emissions have been promoted and implemented in many countries in the world. LÄS MER

  3. 12. Power-generation, Power-electronics and Power-systems issues of Power Converters for Photovoltaic Applications

    Sammanfattning : The thesis deals with issues related to solar energy systems, or more specifically, the electric systems of photovoltaic (PV) installations. Initially aspects of planning and estimating the performance of a PV-installation are considered. LÄS MER

  4. 13. Power Grid Resilience to High Impact Low Probability Events

    Författare :Samuel Forsberg; Mikael Bergkvist; Karin Thomas; Lars Nordström; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extreme weather; HILP events; offshore wind; power grid; resilience; vulnerability; Electrical Engineering with specialization in Systems Analysis; Elektroteknik med inriktning mot systemanalys;

    Sammanfattning : The electrification of societies and the decarbonisation of electricity production are changing energy systems worldwide. A fast transition towards the replacement of fossil fuels by intermittent renewable energy sources is expected in the next decades to combat climate change. LÄS MER

  5. 14. Expansion Governance of the Integrated North Seas Offshore Grid

    Författare :João Gorenstein Dedecca; Paulien M. Herder; Rudi A. Hakvoort; Amineh Ghorbani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Union; expansion planning; governance; HVDC; myopic optimization; North Seas; offshore grid; offshore wind; simulation;

    Sammanfattning : The expansion of offshore power transmission and generation in the North Seas of Europe is accelerating rapidly. This is due to several drivers, including the decarbonization and reform of the European power system, and innovations in offshore wind and high-voltage direct current transmission. LÄS MER

  7. 15. Integration of Non-synchronous Generation - Frequency Dynamics

    Författare :Johan Björnstedt; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency control; Frequency dynamics; Frequency response; Non-synchronous generation; Power system; Synthetic inertia; Wind power;

    Sammanfattning : Traditionally the predominant generation has been large synchronous generators providing the system inertia. Nowadays when wind power and other non-synchronously connected units displaces this synchronous generation, the system inertia is reduced. Hence higher rate of change of frequency and larger frequency deviations are expected. LÄS MER
