  1. 16. Balancing variable renewable electricity generation using combined heat and power plants, large-scale heat pumps, and thermal energy storages in Swedish district heating systems

    Författare :Svante Monie; Magnus Åberg; Annica Nilsson; Joakim Widén; Magnus Wallén; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating systems; Power-to-Heat; Heat pumps; Combined heat and power; Thermal energy storage; Power balance; Variable renewable electricity; Biomass fuel; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Sammanfattning : The global ambitions to hamper the greenhouse effect has led to ambitious targets for increasing renewable energy use. This, in combination with recent years' vast development of wind and solar power, implies that there will be significant amounts of variable renewable electricity (VRE) in future energy systems.

  3. 17. Solcellssystem i svenska byggnader: Förutsättningar relaterade till lönsamhet och montage

    Författare :Maria Haegermark; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; buildings; economic analysis; roofs; mounting systems; solar photovoltaics;

    Sammanfattning : As a result of decreased solar photovoltaic (PV) system prices, the Swedish PV market has grown rapidly the last few years, with the majority of new capacity installed inbuildings. However, the market is still small and this licentiate thesis therefore aims to help facilitating for a continued positive development by adding to the knowledge about conditions related to PV in Swedish buildings.

  4. 18. Decentralization in the electricity system: At the household, community and city levels

    Författare :Verena Heinisch; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Smart city; Storage systems; Power-to-heat; Optimization; Energy system modeling; Photovoltaic; Decentralization; Community energy; Prosumers;

    Sammanfattning : Recent years have seen a rise in the number of implementations of small-scale generation and storage technologies for electricity and heat at different levels in the energy system. This trend towards decentralization of the system is driven by rapid decrease in technology costs, as well as the intentions expressed by various stakeholders to contribute to a carbon-neutral energy system.

  5. 19. Analysis and Forecasting of Utility-Scale Hybrid Wind and PV Power Parks

    Författare :Oskar Lindberg; David Lingfors; Joakim Munkhammar; Johan Arnqvist; Jakub Jurasz; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-located; probabilistic; forecasting; trading; wind; solar; variability; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Sammanfattning : The increasing share of wind and photovoltaic (PV) power in the electricity generation mix pose challenges in power system management due to their non-dispatchable and intermittent nature. Co-locating wind and PV parks, forming utility-scale hybrid power parks (HPPs), means that the sources can share grid connection, land, permitting procedures as well as operation and maintenance work.

  7. 20. Buildings' Transition to Active Nodes: Assessing the Viability of DC Distribution, PV and Battery Storage

    Författare :Patrik Ollas; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Buildings; Battery storage; Energy management; Solar photovoltaic; Direct current;

    Sammanfattning : Historically, buildings have been passive nodes in the electric grid system with one-way power flows. However, with the recent market development of solar photovoltaic (PV) and stationary behind-the-meter battery storage systems, buildings are now transitioning to active nodes, offering bi-directional power flows.
