  1. 1. Unlocking the Potential of Battery Energy Storage Systems in the Nordic Frequency Regulation Markets : A techno-economic analysis to evaluate long-term profitability

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Theodor Ingman; Henrik von Sivers; [2023]
    Nyckelord :;

    Sammanfattning : As the Swedish power system has increased its shares of production coming from intermittent renewables, the production coming from large rotational units as nuclear, and hydropower, has decreased. Thereby, the power system has become more sensitive to sudden changes between production and consumption of electricity, increasing the risk of disruptions in the electricity grid. LÄS MER

  3. 2. Design and evaluation of a plain MPI-based cluster execution backend for the SkePU 3 skeleton programming framework

    Master-uppsats, Linköpings universitet/Programvara och system

    Författare :Alexander Zeijlon; [2023]
    Nyckelord :SkePU; skeleton programming; algorithmic skeletons; HPC; cluster; parallel programming; MPI; OpenMP; CUDA; Hybrid; NUMA;

    Sammanfattning : SkePU 3 is a framework for parallel program execution that uses higher order functions called skeletons, which provide a layer of abstraction between user code and the parallel implementation it provides through its backends. The backend that enables SkePU to run on an HPC cluster has a slowdown of a factor two. LÄS MER

  4. 3. THE COUPLING OF A DOUBLE QUANTUM DOT TO MICROWAVE PHOTONS

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Mohamed Abrash; [2023]
    Nyckelord :Quantum computing; Qubit; Double quantum dot DQD ; Microwave resonator; Quantum integrated circuits; Sweet spots; Hybrid quantum circuits.; Physics and Astronomy;

    Sammanfattning : In this study, we derive a mathematical description of a double quantum dot (DQD) embedded in a microwave resonator starting from classical electrostatics. DQDs are a promising platform for building quantum computers and have important applications in quantum sensing and the study of light-matter interactions. LÄS MER

  5. 4. Passiva, hybrida och aktiva metoder för att tillgodose och minska kylbehov i ett flerbostadshus med påverkan av klimatförändring

    Master-uppsats, KTH/Hållbara byggnader

    Författare :Niklas Åström; [2023]
    Nyckelord :;

    Sammanfattning : Climate change will have a big impact on the built environment especially relating to indoor climate and energy usage. Higher temperatures and insufficient adaptation to heat can have several negative side effects on occupants. LÄS MER

  7. 5. Dynamic Control, Modeling and Sizing of Hybrid Power Plants : Investigating the optimum usage of energy storage for Fortum’s hydropower

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Klas Lindgren; [2023]
    Nyckelord :Hydropower Plants; Energy Storage Systems; Hybrid Units; Frequency Regulation; Modeling; XGBoost Regression; Vattenkraftverk; Energilagringsystem; Hybridkraftverk; Frekvensreglering; Modellering; XGBoost Regression;

    Sammanfattning : The rapidly evolving Nordic Power System demands enhanced flexibility and robustness in electricity production. The traditional role of hydropower plants in regulating the grid frequency has been challenged by new criteria for dynamic stability, which some units struggle to meet due to their relatively poor dynamic performance.
