  1. 11. Increasing the hosting capacity of distributed energy resources using storage and communication

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Nicholas Etherden; Luleå tekniska universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable Energy Generation; Energy Storage; Hosting Capacity; Curtailment; Demand Response; Dynamic Line Rating; Power System Communication; Smart Grid; Technology - Electrical engineering; electronics and photonics; Förnyelsebara energikällor; Energilagring; Acceptansgräns; Kommunikation i kraftsystem; Smarta elnät; Teknikvetenskap - Elektroteknik; elektronik och fotonik; Energy Engineering; Energiteknik; Electric Power Engineering; Elkraftteknik;

    Abstract : The use of electricity from Distributed Energy Resources like wind and solar powerwill impact the performance of the electricity network and this sets a limit to theamount of such renewables that can be connected. Investment in energy storage andcommunication technologies enables more renewables by operating the networkcloser to its limits. READ MORE

  2. 12. Dampening variation in the European Wind Energy System

    University dissertation from Luleå : Luleå tekniska universitet

    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

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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mikael Levin; Umeå universitet.; [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.
