  2. 6. 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

  4. 7. Wind Power Integration in Power Systems with Transmission Bottlenecks

    Author : Julija Matevosyan; Lennart Söder; Olav Bjarte Fosso; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind power; hydro power; transmission bottlenecks; stochastic optimization; Electric power engineering; Elkraftteknik;

    Abstract : During the last two decades, the increase in electricity demand and environmental concern resulted in fast growth of power production from renewable sources. Wind power is one of the most efficient alternatives. READ MORE

  5. 8. Security of Electricity Supply in Power Systems : Establishing a Global Framework for Assessing Power System Health and Analyzing Outage Statistics in Sweden

    Author : Sanja Duvnjak Zarkovic; Patrik Hilber; Ebrahim Shayesteh; Christina Papadimitriou; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; security of electricity supply; power system health; outage statistics; data analysis; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The primary objective of this thesis is to enhance the security of electricity supply by providing a holistic perspective and introducing a comprehensive framework for assessing power system health. This novel approach aims for a thorough evaluation of the system’s overall performance and well-being, using the physical dimensions of the security of supply as the foundation for a power system health index.

  6. 9. Variability and variation management in a renewable electricity system -large-scale wind- and solar power deployment in Europe

    Author : Lina Reichenberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marginal cost of electricity; VRE; variability smoothing; solar power; power systems; renewable energy; wind power; energy systems modelling;

    Abstract : The large-scale deployment of wind and solar power poses challenges to the electricity system by introducing variability on the generation side. To handle these variations, variation management strategies can be employed to ensure that generation meets demand. READ MORE

  7. 10. On Distributed Balancing of Wind Power Forecast Deviations in Competitive Power Systems

    Author : Richard Scharff; Lennart Söder; Mikael Amelin; Gerard L. Doorman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; balancing; wind power integration; electricity market; wind power variations; wind power forecast errors;

    Abstract : Wind power generation does, on the one hand, contribute to a less polluting and more sustainable electric power generation mix. On the other hand, the uncertainty and the variability of the power output do challenge the operation of the power system: hourly variations in wind power generation are hardly predictable in a precise way.
