  1. 11. Preparation and performance of energy storage materials and application for recovery of industrial waste heat

    Författare :Weilong Wang; Jinyue Yan; Fredrik Setterwall; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase change materials; Polyethylene glycol; Silicon dioxide; Form-stable; Thermal conductivity; Expanded graphite; Industrial heat; M-TES; ; Chemical energy engineering; Kemisk energiteknik;

    Sammanfattning : Due to the rapid increase of energy consumption and the environmental concerns on climate change caused by the fossil fuel combustion, it becomes a big issue on how to use alternative renewable energy resources to replace fossil fuel and to improve energy utilization efficiency. In Sweden, there are plenty of detached buildings without connection with district heating (DH) network, which use oil to supply the hot water for space heating and tap water. LÄS MER

  3. 12. Towards the design of flexibility management in smart grids : A techno-institutional perspective

    Författare :Cherrelle Eid; Rudi Hakvoort; Weijnen Weijnen; Yashar Araghi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy; electricity; regulation; European Union; distribution networks; balancing markets; distributed energy resources; congestion management; market transparency; European governance; European modes of regulation; regulatory change; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The European policy focus on smart grids implies their development as an indispensable part of the future power system. However, the definition of a smart grid is broad and vague, and the actual implementation of a smart grid can differ significantly, depending on the stakeholders involved. LÄS MER

    Sammanfattning : Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. LÄS MER

  5. 14. Designing Electricity Distribution Network Charges for an Efficient Integration of Distributed Energy Resources and Customer Response

    Författare :Ibtihal Abdelmotteleb; Tómas Gómez; Javier Reneses; Rafael Cossent Árin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; customer response; distributed energy resources; distribution network charges; local flexibility mechanisms; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : A significant transformation has been gradually taking place within the energy sector, mainly as a result of energy policies targeting environmental objectives. Consequently, the penetration of Distributed Energy Resources (DERs) has been escalating, including self-generation, demand side management, storage, and electrical vehicles. LÄS MER

  7. 15. Energy Management in Smart Cities

    Författare :Christian Francisco Calvillo Munoz; Lennart Söder; Alvaro Sanchez; José Villar; Rafael Cossent; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system model; Smart city; Distributed energy resources; Distributed generation; EV; Metro; Energy markets; Planning and operation model; Energy Technology; Energiteknik;

    Sammanfattning : Models and simulators have been widely used in urban contexts for many decades. The drawback of most current models is that they are normally designed for specific objectives, so the elements considered are limited and they do not take into account the potential synergies between related systems.
