  1. 1. Drop-weight impact tests on reinforced concrete beams

    Master-uppsats, KTH/Betongbyggnad

    Författare :John Abdalnour; Milad Saliba; [2023]
    Nyckelord :;

    Sammanfattning : This master's thesis aimed to investigate the behaviour of reinforced concrete beams under dynamic loading conditions, specifically focusing on understanding shear failure. The study was conducted with KTH Royal Institute of Technology, the Swedish Fortifications Agency, and Tyréns. LÄS MER

  3. 2. Renewables and electrification in Europe, A critical analysis

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Thibault Damas; [2023]
    Nyckelord :Electrification; Renewables; Storage; Flexibility; Transmission; Europe; Technology and Engineering;

    Sammanfattning : Electrification of processes has become the cornerstone of the strategy to decarbonise energy supply, especially in recent years. This study aims to define the main issues underlying the electrification of the European energy mix, especially those caused by an increasing share of intermittent energies. LÄS MER

  4. 3. Supporting Frequency Stability With Batteries in Low Inertia Power Systems

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

    Författare :Sophie-Linn Karlsson; Tim Asking; [2022]
    Nyckelord :Battery Power Support; Fast Frequency Reserves; Frequency Containment Reserves; Inertia; Renewable Energy Sources;

    Sammanfattning : As the share of power electronics-based renewable energy sources increases in power systems, the system inertia provided by conventional generation is reduced. Inertia is an important factor in the grid's frequency stability, and with its reduction comes challenges to ensure the reliability of the grid. LÄS MER

  5. 4. Simulation of a Battery Energy Storage System for Fast Frequency Reserve Support.

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Pathirage Dona Upekha Nimanthi Pathirage; [2022]
    Nyckelord :Energy Storage; Renewable Energy; Battery; Fast Frequency Reserve; Lithium-ion;

    Sammanfattning : Electricity providers has a growing interest in moving towards Renewable Energy Sources (RES) for power generation due to their attractive features. This has caused phasing out of coal, oil and nuclear power plants which use large synchronous generators for power production. LÄS MER

  7. 5. Dynamic Modelling of the Patient Circuit for High Frequency Ventilation

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Samuel Eriksson; [2022]
    Nyckelord :Mechanical ventilation; high frequency ventilation; patient circuit dynamics; parameter estimation; system identification; Mekanisk ventilation; högfrekvent ventilation; patientkretsens dynamik; parameterestimering; systemidentifiering;

    Sammanfattning : Artificial breathing is vital when it comes to treatment of critically ill patients where the natural breathing mechanism is insufficient. With the help of mechanical ventilators, the natural breathing mechanism of the patient can be assisted or even exchanged with the artificial breathing from the machine. LÄS MER
