  2. 1. 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

  4. 2. Electromagnetic transformer modelling including the ferromagnetic core

    Author : David Ribbenfjärd; Göran Engdahl; David Jiles; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power transformer; hysteresis; dynamic hysteresis; dynamic magnetization; eddy currents; excess losses; leakage flux; winding model; core model; magnetic measurements; magnetic materials; Electric power engineering; Elkraftteknik;

    Abstract : In order to design a power transformer it is important to understand its internal electromagnetic behaviour. That can be obtained by measurements on physical transformers, analytical expressions and computer simulations. READ MORE
