  2. 6. Power-generation, Power-electronics and Power-systems issues of Power Converters for Photovoltaic Applications

    Author : Björn Lindgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power systems; bang-bang control; shading tolerance; power quality; photovoltaic; embedded generation; current control; solar power generation;

    Abstract : The thesis deals with issues related to solar energy systems, or more specifically, the electric systems of photovoltaic (PV) installations. Initially aspects of planning and estimating the performance of a PV-installation are considered. READ MORE

  4. 7. Automating Power Quality Analysis

    Author : Emmanouil Styvaktakis; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pattern classification; expert systems; induction motors; power system transients; voltage dips; power system faults; power quality; Kalman filtering; power system monitoring; transformer saturation; short time Fourier transform;

    Abstract : The increased requirements on supervision, control, and performance in modern power systems make power quality monitoring a common practise for utilities. Large databases are created and automatic processing of the data is required for fast and effective use of the available information. READ MORE

  5. 8. 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

  6. 9. Probabilistic security management for power system operations with large amounts of wind power

    Author : Camille Hamon; Lennart Söder; Louis Wehenkel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power systems; wind power; probabilistic security management; chance-constrained optimal power flow; monte-carlo; importance sampling; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Power systems are critical infrastructures for the society. They are therefore planned and operated to provide a reliable eletricity delivery. The set of tools and methods to do so are gathered under security management and are designed to ensure that all operating constraints are fulfilled at all times. READ MORE

  7. 10. 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
