  2. 6. Power-generation, Power-electronics and Power-systems issues of Power Converters for Photovoltaic Applications

    Author : Björn Lindgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power systems; bang-bang control; shading tolerance; power quality; photovoltaic; embedded generation; current control; solar power generation;

    Abstract : 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. READ MORE

  4. 7. On Distributed Balancing of Wind Power Forecast Deviations in Competitive Power Systems

    Author : Richard Scharff; Lennart Söder; Mikael Amelin; Gerard L. Doorman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; balancing; wind power integration; electricity market; wind power variations; wind power forecast errors;

    Abstract : Wind power generation does, on the one hand, contribute to a less polluting and more sustainable electric power generation mix. On the other hand, the uncertainty and the variability of the power output do challenge the operation of the power system: hourly variations in wind power generation are hardly predictable in a precise way.

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

    Author : Maria Sandström; Erik Dotzauer; Chris Bales; Pei Huang; Björn Laumert; Högskolan i Gävle; []
    Keywords : 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 ;

    Abstract : 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. READ MORE

  6. 9. On optimal hydropower bidding in systems with wind power : Modeling the impact of wind power on power markets

    Author : Magnus Olsson; Lennart Söder; Stein-Erik Fleten; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydropower; wind power; stochastic modeling; optimization; Electric power engineering; Elkraftteknik;

    Abstract : The introduction of large amounts of wind power into power systems will increase the production uncertainties due to unforeseen wind power production variations. This will have a significant impact on the required balance management quantities. READ MORE

  7. 10. Design Aspects of Inductive Power Transfer Systems for Electric Vehicle Charging

    Author : Daniel Pehrman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stray field measurements; shielding; electric vehicle charging; inductive power transfer; full-bridge resonant inverter; finite element method FEM ; series-parallel compensation; coupled inductors; series-series compensation; silicon carbide;

    Abstract : During the last decade the transition towards electric propelled vehicles has had an upswing and electric vehicle (EV) sales has increased steadily. This is much due to legislations on lowering emissions but also due to lower total cost of ownership. READ MORE
