  6. 4. Towards efficient modeling and simulation of district energy systems

    Author : Johan Simonsson; Wolfgang Birk; Khalid Atta; Mika Ruusunen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

    Abstract : Dynamic simulation of district energy systems has an increased importance in the transition towards renewable energy sources, lower temperature district heating grids and waste heat recovery from industrial plants and data centers. However, a city-scale, automatically generated and updated simulator that can be used for the whole lifecycle of the plant remains a distant vision. READ MORE
