  1. 1. Evaluation and variability of power grid hosting capacity for electric vehicles : Case studies of residential areas in Sweden

    Författare :Maria Sandström; Erik Dotzauer; Chris Bales; Pei Huang; Björn Laumert; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hosting capacity HC ; Power grid; Electric vehicle EV ; Charging strategies; Power flow simulations; Uncertainty analysis; Hållbar stadsutveckling; Sustainable Urban Development; inget Strategiskt forskningsområde SFO ; no Strategic Research Area SFO ;

    Sammanfattning : Electric vehicles (EVs) are increasing in popularity and play an important role in decarbonizing the transport sector. However, a growing EV fleet can cause problems for power grids as the grids are not initially designed for EV charging. The potential of a power grid to accommodate EV loads can be assessed through hosting capacity (HC) analysis. LÄS MER

  2. 2. Wind Power in Areas with Limited Export Capability

    Författare :Julija Matevosyan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind power; transmission capacity; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Manufacturing engineering and work sciences; Produktion och arbetsvetenskap;

    Sammanfattning : During the last two decades, increase in electricity demand and environmental concern resulted in fast growth of power production from renewable sources. Wind power is one of the most efficient alternatives. LÄS MER

  3. 3. Peak and Power Reduction in Multicarrier Communication Systems

    Författare :Niklas Andgart; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; line driver; Signal processing; Signalbehandling; Telecommunication engineering; power reduction; DSL; DMT; tone reservation; PAR; Peak to average ratio;

    Sammanfattning : Broadband multicarrier communication suffers from a large signal span, causing problems in both wireless and wireline systems. This is commonly referred to as a high peak to average ratio (PAR), and leads to a high power consumption, which is an important limitation in many communication systems. LÄS MER

  4. 4. What have residents got to do with it? : Variations in energy use and energy-related behaviours in single-family houses

    Författare :Carolina Hiller; Jesper Arfvidsson; Thorbjörn Laike; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy use variations; energy-related behaviour; single-family houses; households; residents; multi-disciplinary; field measurements; times-use diaries; energy use over time; load curves; power peaks; energy measurements; residential houses;

    Sammanfattning : To achieve global energy goals, energy use in residential buildings must decrease. The implementation of technical measures is crucial but alone it is not sufficient; residents need to change their behaviour as well. LÄS MER

  5. 5. Multilevel Inverter for Wave Power Conversion

    Författare :Remya Krishna; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : This thesis deals with the electrical system analysis of a Wave Energy Converter (WEC) for the objective of grid connection. The Linear Permanent Magnet Generator (LPMG) is modeled and validated with experimental results. The comparison studies establish that this model is useful for the subsequent system modeling and performance analysis. LÄS MER
