  1. 1. Temperature Shocks and Price Stability

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Klara Strömberg; [2024]
    Nyckelord :Climate Change; Price Stability; Local Projections; United Kingdom;

    Sammanfattning : This thesis investigates the interplay between temperatures and prices in an advanced economy context. To this end, I estimate the impulse response to a 1°C temperature anomaly on the UK economy. LÄS MER

  3. 2. Machine Learning model applied to Reactor Dynamics

    Master-uppsats, KTH/Fysik

    Författare :Dionysios Dimitrios Nikitopoulos; [2023]
    Nyckelord :Master Thesis; Machine Learning; stability; Energy distribution profiles; Prediction; frequency; decay ratio; Data processing; POLCA-T; Pytorch; testing data; RMSE. ii;

    Sammanfattning : This project’s idea revolved around utilizing the most recent techniques in MachineLearning, Neural Networks, and Data processing to construct a model to be used asa tool to determine stability during core design work. This goal will be achieved bycollecting distribution profiles describing the core state from different steady statesin five burn-up cycles in a reactor to serve as the dataset for training the model.

  4. 3. Battery storage implementation in Sweden and sizing software development

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

    Författare :Santiago Moreano Rojas; [2023]
    Nyckelord :;

    Sammanfattning : Due to the rampant growth of the penetration of renewables into the electrical grids across the world, more challenges appear in the way to assure the optimal operation of the energy system. More particularly, in the case of Sweden, the nuclear power decommissioning tendency and the 100% renewable energy target by 2040, set two strong additional motivations for the rise of issues regarding variability, uncertainty, stability, balancing and quality in the grid.

  5. 4. Method Development & Analysis of Seals using FEM

    Master-uppsats, KTH/Maskinkonstruktion

    Författare :Lovisa Svanborg Östlin; [2023]
    Nyckelord :FEM; guidelines; hyperelastic materials; hyperelastic material models; method development; seals; FEM; riktlinjer; hyperelastiska material; hyperelastiska materialmodeller; metodutveckling; tätningar;

    Sammanfattning : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. LÄS MER

  7. 5. Analys och vidareutveckling av simuleringsmiljö för LFC-reglering inom NBM-programmet

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Marcus Baumann; [2023]
    Nyckelord :Load frequency control; Power system simulator; Nordic Balancing Model; ARISTO;

    Sammanfattning : The control and balancing measures for achieving safe grid operation in the Nordic power grid is becoming increasingly complex with larger penetrations of renewable power, new guidelines aiming to increase digitalisation and automation alongside integration into European balancing platforms. The power grid operators are faced with new challenges for safely operating the grid leading to an increased need for theoretical and practical education. LÄS MER
