  1. 16. Mean Wind and Turbulence Conditions in the Boundary Layer above Forests

    Författare :Johan Arnqvist; Hans Bergström; Anna Rutgersson; Stefan Söderberg; Søren Larsen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wind power; Forest; Turbulence; Waves; Spectra; Wind model; Atmospheric stability; Vindkraft; Skog; Turbulens; Vågor; Spektra; Modell; Atmosfärisk stabilitet;

    Sammanfattning : As wind turbines have grown, new installation areas become possible. Placing wind turbines in forested landscapes introduce uncertainties to the wind resource estimation. LÄS MER

  3. 17. Frequency Response by Wind Farms in Islanded Power Systems with High Wind Power Penetration

    Författare :Mattias Persson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synthetic inertia; rate of change of frequency; inertia emulation; variable speed wind turbine; frequency control;

    Sammanfattning : The integration of variable speed wind turbines (VSWT) in power systems keep increasing inorder to reduce the emission of green house gases. This increase of power electronic converterinterfaced generation causes a decrease of power system inertia and issues previously existingin power systems tend to become more complicated and new solutions should be evaluated.

  4. 18. Convex Optimal Power Flow Based on Second-Order Cone Programming: Models, Algorithms and Applications

    Författare :Zhao Yuan; Mohammad Reza Hesamzadeh; Mario Paolone; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal Power Flow; Second-Order Cone Programming; Distribution Locational Marginal Pricing; Wind Power; Super Grid; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Optimal power flow (OPF) is the fundamental mathematical model to optimally operate the power system. Improving the solution quality of OPF can help the power industry save billions of dollars annually. Past decades have witnessed enormous research efforts on OPF since J. LÄS MER

  5. 19. Mathematical modelling and methodology for cost optimization of variable renewable electricity integration
