  1. 1. Cold Load Pick-up

    Författare :Evert Agneholm; Chalmers University of Technology; []
    Nyckelord :cold load pick-up; load modelling; field measurements; blackout; power system restoration;

    Sammanfattning : The load behaviour of the industrial and residential sector following different types of outages is dealt with in this dissertation. Data on the power consumption after these outages have been used for deriving models of the cold load pick-up. LÄS MER

    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric power engineering; Elkraftteknik;

    Sammanfattning : The rapid development of wind power technology is reshaping conventional power grids in many countries across the world. As the installed capacity of wind power increases, its impact on power grids is becoming more important. LÄS MER

  4. 4. A hydropower perspective on flexibility demand and grid frequency control

    Författare :Linn Saarinen; Urban Lundin; Bengt Carlsson; Per Norrlund; Evert Agneholm; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; hydropower; frequency control; balancing; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : The production and consumption of electricity on the power grid has to balance at all times. Slow balancing, over days and weeks, is governed by the electricity market and carried out through production planning.  Fast balancing, within the operational hour, is carried out by hydropower plants operating in frequency control mode.
