  1. 1. The Impact of Oil Prices on Carbon Dioxide Emission Levels in Sweden : a time-series regression analysis of Sweden

    University essay from SLU/Dept. of Economics

    Author : Tilde Löfgren Weinebrandt; [2023]
    Keywords : oil prices; CO2 emissions; oil price elasticity; Multiple Linear Regression Model; Sweden; correlation;

    Abstract : Globally, CO2 emissions have increased over the last decades. This trend has been broken in Sweden, where CO2 emissions are declining. Oil is one of Sweden's largest sources of energy, accounting for over 20 % of all energy consumption, and oil combustion is a large source of CO2 emissions. READ MORE

  3. 2. Dynamic Warning Signals and Time Lag Analysis for Seepage Prediction in Hydropower Dams : A Case Study of a Swedish Hydropower Plant

    University essay from Uppsala universitet/Datalogi

    Author : Lovisa Olsson; Julia Hellström; [2023]
    Keywords : hydropower; dam safety; dam monitoring; seepage; prediction models; data-driven methods; artificial intelligence; AI;  linear regression; Support Vector Regression; SVR; Long Short-Term Memory; LSTM;

    Abstract : Hydropower is an important energy source since it is fossil-free, renewable, and controllable. Characteristics that become especially important as the reliance on intermittent energy sources increases. However, the dams for the hydropower plants are also associated with large risks as a dam failure could have fatal consequences. READ MORE

  4. 3. Integration of wind energy into the UK electricity grid and management within the distribution future energy scenarios

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Patrick O'Mahony; [2023]
    Keywords : Wind energy; renewable energy; network development plans; distribution future energy scenarios; electricity networks;

    Abstract : In order to achieve Net Zero emissions in the UK by 2050 and decarbonize the energy sector the integration of increased volumes of additional renewable wind energy is critical. Distribution network operators face challenges in increasing the capacity of this variable source of energy onto the electricity networks. READ MORE

  5. 4. Line Distance Protection in Power Grids with Variable Renewable Energy Sources : An Investigation on Time Domain Distance Protection via Parameter Estimation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ludvig Ringaby; [2023]
    Keywords : Distance protection; Power system protection; Time domain distance protection; Differential Equation Algorithm; Variable renewable energy; IBR; Distansskydd; Skyddssystem i elkraftsystem; Tidsdomän distansskydd; Differentialekvationsalgoritm; Variabel förnybar energi;

    Abstract : Variable renewable energy sources typically connect to the power grid through power electronic interfaces. Increased use of such sources can cause issues for conventional distance protection. READ MORE

  6. 5. Parallel Query Systems : Demand-Driven Incremental Compilers

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Christofer Nolander; [2023]
    Keywords : Query Systems; Parallelism; Incremental Computation; Compiler Architecture; Dependency Tracking; Query system; Parallelism; inkrementella beräkningar; kompilatorer; beroende spårning;

    Abstract : Query systems were recently introduced as an architecture for constructing compilers, and have shown to enable fast and efficient incremental compilation, where results from previous builds is reused to accelerate future builds. With this architecture, a compiler is composed of several queries, each of which extracts a small piece of information about the source program. READ MORE
