  1. 1. Modeling of Wind Turbines for Power System Studies

    Författare :Tomas Petru; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flicker; fault response; power quality; wind turbine; power system stability; measurements; prediction; verification; grid simulation; modeling;

    Sammanfattning : The power quality impact of wind turbines on the electric grid and the response of the wind turbines to faults in the electric grid are investigated in this thesis. A detailed model of a stall-regulated, fixed-speed wind turbine system capable of predicting the flicker impact on the connected grid is presented and compared with field measurements. LÄS MER

  3. 2. Modeling, Control and Protection of Low-Voltage DC Microgrids

    Författare :Daniel Salomonsson; Lennart Söder; Brian K. Johnsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circuit transient analysis; dc power systems; dispersed storage and generation; load modeling; power conversion; power distribution control; power distribution faults; power distribution protection; power electronics; Electric power engineering; Elkraftteknik;

    Sammanfattning : Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER
