  1. 1. Wind power wake modelling : Development and application of an actuator disc method for industrial utilization

    Författare :Nikolaos Simisiroglou; Stefan Ivanell; Thorsten Lutz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wind power; Offshore wind farm; Wakes; Actuator Disc Method ACD ; Computational Fluid Dynamics CFD ; Reynolds Average Navier–Stokes RANS ; WindSim; PHOENICS;

    Sammanfattning : As a wind turbine extracts energy from the wind it creates a region downstream where the wind velocity is decreased and the urbulence intensity is increased, this region is commonly called the wake region. Today’s wind farms include a large number of wind turbines position in tight layouts. LÄS MER

  3. 2. Modelling Wind Power for Grid Integration Studies

    Författare :Jon Olauson; Mikael Bergkvist; Mats Leijon; Thomas Hamacher; Uppsala universitet; []
    Nyckelord :Wind power; Wind power modelling; Intermittent renewables; Variability; Integration or renewables; Reanalysis data; Power system studies;

    Sammanfattning : When wind power and other intermittent renewable energy (IRE) sources begin to supply a significant part of the load, concerns are often raised about the inherent intermittency and unpredictability of these sources. In order to study the impact from higher IRE penetration levels on the power system, integration studies are regularly performed. LÄS MER

  4. 3. Wind power in thermal power systems

    Författare :Lisa Göransson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integration; wind power; variation moderator; PHEV; storage;

    Sammanfattning : AbstractWind power is a key technology in the effort to transform the power system in order to reduce its climate impact. However, the ability of wind power to reduce CO2-emissions depends on the properties of the power system. LÄS MER

  5. 4. Generation Reliability for Isolated Power Systems with Solar, Wind and Hydro Generation

    Författare :Jimmy Ehnberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Generation reliability; Isolated power systems; Wind power; Solar power; Renewable energy; Stochastic modelling;

    Sammanfattning : This licentiate thesis deals with reliability issues for small isolated power systems. The focus is on power systems in remote areas based entirely on renewable energy sources. The sources investigated in this thesis are mainly solar and wind power; stochastic models for these energy sources are presented. LÄS MER

  7. 5. Efficient Simulation Methods of Large Power Systems with High Penetration of Renewable Energy Resources : Theory and Applications

    Författare :Ebrahim Shayesteh; Lennart Söder; Enrique Acha; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system simplification; power system reduction; power system aggregation; power system equivalencing; renewable energy resources; wind power modelling; storage allocation problem; spinning reserve determination; multi-area power system analyses; power system operation and planning; electricity market analysis.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Electrical energy is one of the most common forms of energy these days. Consequently, electric power system is an indispensable part of any society. LÄS MER
