1. 6. 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

3. 7. Where the Wind Blows : the socio-political geography of wind power development in Finland, Norway and Sweden

   Författare :Johanna Liljenfeldt; Örjan Pettersson; Kerstin Westin; Olof Stjernström; Peter Schmitt; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; wind power; planning; land use; participation; power relations; energy justice; mixed methods; Finland; Norway; Sweden; Social and Economic Geography; kulturgeografi;

   Sammanfattning : This thesis analysis the planning process for large-scale wind power development in Finland, Norway and Sweden. The aim is to explore the emerging power relations and socio-economic dynamics of the negotiation, planning and realization of this new development. LÄS MER

4. 8. Wind-turbine harmonic emissions and propagation through a wind farm

   Författare :Kai Yang; Åke Larsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy; Electric power system; Wind power; Power quality; Power system harmonics; Electric Power Engineering; Elkraftteknik; Energy Engineering; Energiteknik;

   Sammanfattning : The increasing demand for sustainable energy is one of the driving forces behind the increasing use of wind power by means of wind-turbines in electric power systems. Modern wind turbines commonly employ variable-speed-generator technology associated with a power-electronic converter as part of the grid connection. LÄS MER

5. 9. Locating Wind Power Policy : The Mechanics of Policy Subsystem Interactions

   Författare :David Newell; Simon Matti; Sverker Jagers; Charlotta Charlotta; Erik Hysing; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; policy analysis; policy implementation; advocacy coalition framework; network management; wind power; renewable energy; Political Science; Statsvetenskap;

   Sammanfattning : This dissertation investigates the drivers behind political decision-making and the policy outcomes resulting from political decisions. It is proposed that in policy processes where political decisions are made at multiple levels or across multiple policy subsystems, policy outcomes can be understood in terms of the mechanisms (i.e. LÄS MER

7. 10. 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
