  1. 1. Assembling the Smart Grid : On the Mobilization of Imaginaries, Users and Materialities in a Swedish Demonstration Project

    Författare :Anna Wallsten; Harald Rohracher; Jonas Anshelm; Vasilis Galis; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Smart grids; demonstration projects; translations; sociotechnical imaginaries; material participation; users; Smarta elnät; demonstrationsprojekt; översättning; sociotekniska föreställningar; material participation; användare;

    Sammanfattning : Influential actors refer to smart grids as a revamped version of the energy systemwhen they argue for alternative energy pathways, and assign demonstration projects with the task of turning prospects about the future into functional configurations. This thesis explores notions of the smart grid future that are implicitly conveyed in Swedish smart grid strategy and planning documents. LÄS MER

  3. 2. Energy efficiency measures in the built environment - some aspects to consider in Sweden

    Författare :Mattias Gustafsson; Björn O. Karlsson; Mats Rönnelid; Louise Ödlund; Jan-Olof Dalenbäck; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; primary energy; energy efficiency; district heating; building regulations; electric meter; low-voltage distribution networks; electric vehicles; primärenergi; energieffektivitet; fjärrvärme; byggregler; elmätare; elnät; elfordon; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : The traditional energy system as we know it today will change in the future. There is a worldwide concern about the global warming situation and there are different actions implemented to limit the consequences from, mainly, the use of fossil fuels. LÄS MER

  4. 3. Increasing the hosting capacity of distributed energy resources using storage and communication

    Författare :Nicholas Etherden; Joao A Peças Lopes; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Systems; Renewable Energy; Energy Storage; Hosting Capacity; Curtailment; Power Utility Automation; IEC 61850; Smart Grid; Elkraft; Förnyelsebara energikällor; Energilager; Acceptansgräns; Produktionsnedstyrning; Kraftsystemsautomation; IEC 61850; Smarta elnät; Electric Power Engineering; Elkraftteknik;

    Sammanfattning : This thesis develops methods to increase the amount of renewable energy sources that can be integrated into a power grid. The assessed methods include i) dynamic real-time assessment to enable the grid to be operated closer to its design limits; ii) energy storage and iii) coordinated control of distributed production units.

  5. 4. Increasing the hosting capacity of distributed energy resources using storage and communication

    Författare :Nicholas Etherden; Sami Repo; Luleå tekniska universitet; []
    Nyckelord :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; Förnyelsebara energikällor; Energilagring; Acceptansgräns; Kommunikation i kraftsystem; Smarta elnät; Energy Engineering; Energiteknik; Electric Power Engineering; Elkraftteknik;

    Sammanfattning : 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. LÄS MER

  7. 5. A Needs-Based Approach towards Fostering Long-term Engagement with Energy Feedback among Local Residents

    Författare :Aram Mäkivierikko; Fredrik Gröndahl; Olga Kordas; Hossein Shahrokni; Paula M. Bögel; Cristian M Bogdan; KTH; []

    Sammanfattning : In order to reach the current climate goals, energy consumption needs to decrease in all sectors, including households, which produce 20% of the European emissions. However, it is difficult to increase residents’ engagement in their household electricity consumption as it is an ‘invisible’ form of energy, the monetary incentives are often too small and environmental incentives are not very effective.
