  1. 1. Waste-heat Recovery Using Thermoelectricity and Silicon Carbide Power Electronics

    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

  3. 2. Power System Damping - Structural Aspects of Controlling Active Power

    Författare :Olof Samuelsson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics and Electrical technology; controller interaction; mode controllability; mode observability; mechanical equivalent; linear differential-algebraic equations; modal analysis; active power; power system damping; electro-mechanical oscillations; Elektronik och elektroteknik; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. LÄS MER

  4. 3. Variability and variation management in a renewable electricity system -large-scale wind- and solar power deployment in Europe

    Författare :Lina Reichenberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marginal cost of electricity; VRE; variability smoothing; solar power; power systems; renewable energy; wind power; energy systems modelling;

    Sammanfattning : The large-scale deployment of wind and solar power poses challenges to the electricity system by introducing variability on the generation side. To handle these variations, variation management strategies can be employed to ensure that generation meets demand. LÄS MER

  5. 4. On Distributed Balancing of Wind Power Forecast Deviations in Competitive Power Systems

    Författare :Richard Scharff; Lennart Söder; Mikael Amelin; Gerard L. Doorman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; balancing; wind power integration; electricity market; wind power variations; wind power forecast errors;

    Sammanfattning : Wind power generation does, on the one hand, contribute to a less polluting and more sustainable electric power generation mix. On the other hand, the uncertainty and the variability of the power output do challenge the operation of the power system: hourly variations in wind power generation are hardly predictable in a precise way.

  7. 5. Efficient Solid-State Power Amplifiers for RF Power Source Applications

    Författare :Renbin Tong; Dragos Dancila; Jörgen Olsson; Olof Bengtsson; Zoya Popovic; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; back-off efficiency; high efficiency; power source; RF energy; RF measurements; radioisotope production; solid-state power amplifiers; Engineering Science with specialization in Microwave Technology; Teknisk fysik med inriktning mot mikrovågsteknik;

    Sammanfattning : Radio Frequency (RF) power sources are extensively applied in various fields. Radioisotope production, i.e., the production of short-lived radioactive isotopes, for positron emission tomography (PET) is one of the most important applications in the medical and healthcare domains.
