  2. 1. The Frequency of the Frequency : On Hydropower and Grid Frequency Control

    Author : Linn Saarinen; Urban Lundin; Per Norrlund; Bengt Carlsson; Kjetil Uhlen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydropower; frequency control; governors; power system stability; inertia; primary control; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Variations in the electricity consumption and production connected to the power system have to be balanced by active control. Hydropower is the most important balancing resource in the Nordic system, and will become even more important as the share of variable renewable energy sources increases. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Tribology of self-lubricating polymer composites for hydropower applications

    Author : Maria Rodiouchkina; Jens Hardell; Kim Berglund; Jan Ukonsaari; Michał Wasilczuk; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer composites; hydropower; sliding wear; sliding friction; self-lubricating; transfer layers; material characterization; surface analysis; high contact pressure; low sliding speed; Machine Elements; Maskinelement;

    Abstract : The ongoing global climate crisis and its impacts calls for urgent actions, such as significant reduction of CO2 emissions by introducing more renewable energy. This has led to a rapid integration of variable power sources, such as wind and solar power, into the electricity systems. READ MORE

  6. 4. Insights from modeling renewable electricity systems and developing hydropower models

    Author : Hanna Ek Fälth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; renewables; electricity systems; hydropower; nuclear; modeling; Europe; MENA; transmission; available land;

    Abstract : One strategy for reaching a carbon-neutral electricity system is a large-scale deployment of wind and solar power. However, electricity systems with high shares of wind and solar power rely on other technologies, e.g. READ MORE

  7. 5. Weekly planning of hydropower in systems with large volumes of varying power generation

    Author : Charlotta Ahlfors; Mikael Amelin; Magnus Brolin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydropower; literature review; weekly planning; low carbon operation; maintenance scheduling; preventive maintenance; mixed integer linear programming; dynamic programming; cascaded river systems; value of stored water; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Hydropower is the world’s largest source of renewable electricity generation. Hydropower plants with reservoirs provide flexibility to the power systems. READ MORE
