  1. 1. 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

  3. 2. The Application of a TCSC Controller to Improve the Stability of a Power System With High Penetration of Renewable Energy

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

    Author : Albin Wanhainen; Axel Gomér; [2023]
    Keywords : ;

    Abstract : The goal of this project is to examine how a higher penetration of power electronics-basedforms of power production affects system stability and damping. The project covers howpower system stability can be improved by using a Thyristor Controlled Series Capacitor(TCSC) with Power Oscillation Damping (POD). READ MORE

  4. 3. Data-driven cyberattack detection for microgrids

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

    Author : Jiaying Mao; [2022]
    Keywords : Cyberattack detection; Deep learning network; Microgrid; Smart inverter; Cyber-physical system; Distributed system; Detektering av cyberattacker; Djupinlärning nätverk; Microgrid; Smart växelriktare; Cyberfysiska system; Distribuerade system;

    Abstract : Microgrids are undergoing higher penetrations of renewables and associated power electronics, along with precise and sophisticated control and communication networks. However, such cyber-physical systems might suffer from potential cybersecurity threats and inherent low inertia. READ MORE

  5. 4. Estimating CO2 reductions from renewable energy sources : The impact of power system nonlinearities

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

    Author : Kristoffer Berglund; [2022]
    Keywords : CO2 reduction; Dispatch model; Econometric model; Unit commitment; CO2-reduktion; ekonometriska modeller; produktionssimuleringsmodeller;

    Abstract : Replacing conventional generation with renewable generation in power systems is essential for reducing CO2 emissions. It is important to know how effective renewables are in reducing CO2 emissions. Since CO2 reduction cannot be measured directly, different methods have been used to estimate reduction of CO2 emissions. READ MORE

  6. 5. Small Signal Stability of Power Systems With Increased Converter Based Power Production

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

    Author : Gustav Kjellson; Josefin Gustafsson; [2022]
    Keywords : Small signal stability; Power system stabilizer; Renewable energy; Grid following converters; Grid forming converters;

    Abstract : The aim of this project is to analyze how increasing the share of converter-based power production in a power system affects the small signal stability. The project also aims to stabilize systems using Power System Stabilizers (PSSs), and examine the effect of two different types of power electronic converters: grid following (GFL) and grid forming (GFM).
