  1. 11. Dampening variation in the European Wind Energy System

    Author : Lina Reichenberg; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variable renewables; electricity generation; geographic allocation; large-scale penetration of wind power; wind power;

    Abstract : In a future European electricity system, wind power and other variable renewables may constitute a large share of electricity production. This prospect calls for measures to manage the inherent variability of wind power, such as demand-side management, storage, and flexibility of other generation. READ MORE

  2. 12. Energy consumption transition : final household energy consumption in the case of Sweden 1920-2010

    Author : Mikael Levin; Lars-Fredrik Andersson; Ann-Kristin Bergquist; Thomas Pettersson; Bengt Kriström; [2012]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic history; households; energy transition; energy consumption; residential; electrical appliances; Carbon dioxide; emission; ekonomisk historia; Economic History;

    Abstract : This licentiate thesis examines households’ final energy consumption over the long run by measuring their final energy use and examining how structural, institutional and economic factors affected the demand for energy in the residential sector during the period 1920-2010, a period covering the transition from traditional to fossil to renewable energy carriers. I believe that wider understanding of the historical energy transition and energy consumption within the residential sector might help us gain important insights into the long-run development and the factors affecting energy consumption among the households.

    Abstract : The wind power research at the division of Electricity at Uppsala University is aimed towards increased understanding of vertical axis wind turbines. The considered type of wind turbine is an H-rotor with a directly driven synchronous generator operating at variable speed. READ MORE

  4. 14. Energy Consumption and Running Time for Trains modelling of running resistance and driver behaviour based on full scale testing

    University dissertation from Stockholm : KTH

    Author : Piotr Lukaszewicz; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy consumption; Running time; running resistance; driver behaviour; freight; train; energy coasting method; aerodynamic drag; driver model; degree of coasting; slippage; wind; Energy saving; braking ratio; powering ratio; full scale testing; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Abstract : The accuracy in determined energy consumption and runningtime of trains, by means of computer simulation, is dependent upon the various models used. This thesis aims at developing validated models of running resistance, train and of a generaldriver, all based on full scale testing. READ MORE

  5. 15. Electrification of Road Transportation - Implications for the Electricity System

    University dissertation from Stockholm : KTH

    Author : Maria Taljegård; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; highway E39; CO2 emissions; electric vehicle; electric road systems; energy system modelling; variable renewable electricity;

    Abstract : It is incumbent upon the transport sector to reduce its CO2 emissions by replacing fossil fuels with low-carbon alternatives. Suggested strategies include electrification of the road transport sector through the use of electric vehicles (EVs) with static charging, electric road systems (ERS), and the use of electricity to produce fuels.
