    Författare :Arash Edvin Risseh; Hans-Peter Nee; Torbjörn Thiringer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermoelectricity; Power converter; Silicon Carbide; MOSFET; Power management; Thermoelectric generator; Renewable energy; Vehicle; Power electronic; Waste heat; Ultra-low inductance; Power module; Termoelektrisk energiomvandling; Kiselkarbid MOSFET; Effektomvandlare; Förnybar energikälla; Effektelektronik; Spillvärme; Effektmodul; Låg induktiv module; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Energy consumption in the world has increased continuously due to a growing population and increased energy consumption per capita. Moreover, the largest part of consumed energy still comes from fossil sources which in 2016 was more than 130 PWh. 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. 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

  7. 5. Power to gas : Bridging renewable electricity to the transport sector

    Författare :Farzad Mohseni; Per Alvfors; Mats Westermark; Lars Pettersson; Maria Grahn; Björn Frostell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport; renewable electricity; synthetic fuels; energy; power to gas;

    Sammanfattning : Globally, transport accounts for a significant part of the total energy utilization and is heavily dominated by fossil fuels. The main challenge is how the greenhouse gas emissions in road transport can be addressed. Moreover, the use of fossil fuels in road transport makes most countries or regions dependent on those with oil and/or gas assets. LÄS MER
