  2. 6. Hydropower plants and power systems : Dynamic processes and control for stable and efficient operation

    Author : Weijia Yang; Per Norrlund; Urban Lundin; Christophe Nicolet; Uppsala universitet; []
    Keywords : ;

    Abstract : As the largest global renewable source, hydropower shoulders a large portion of the regulation duty in many power systems. New challenges are emerging from variable renewable energy (VRE) sources, the increasing scale and complexity of hydropower plants (HPPs) and power grid. READ MORE

  6. 9. Cost-efficient integration of variable renewable electricity - Variation management and strategic localisation of new demand

    Author : Viktor Walter; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexibility measures; Energy system modelling; smart energy systems; variation management strategies; variable renewable electricity;

    Abstract : The aim of this work was to improve our understanding of how wind power and solar photovoltaics (PV) can be integrated into the European electricity system in a cost-efficient manner. For this, a techno-economic, cost-minimising model of the electricity system is refined for a number of case studies. READ MORE

  7. 10. Orchestrating emerging digital ecosystems : investigating the establishment of an open data platform in the Swedish public transport industry

    Author : Hosea A. Ofe; Johan Sandberg; Jonny Holmström; Henrik Wimelius; Anna Ståhlbröst; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Digital platform ecosystem; platform establishment; emerging ecosystems; orchestrating; control; coordination; generating network effects; creating value; capturing value; attracting users; data- och systemvetenskap; computer and systems sciences;

    Abstract : Digital platforms are affecting most contemporary organizations as they mediate an increasing range and number of interactions in their ecosystems. While the discourse on digital platform ecosystems has gained in interest over the years, it often revolves around dominant global firms and how they utilize their control over governance and architecture configurations to exercise power in shaping trajectories.
