    Nyckelord :Physics; Energy Physics; Energy; Renewable Energy; Wave Power; CorPower Ocean; Point Absorber; Array Modelling; Farm modelling; Fysik; Energifysik; Energi; Vågkraft; Förnyelsebar Energi;

    Sammanfattning : In this thesis, a model has been developed to analyze the behavior of wave energy converter arrays in the frequency domain. This development serves the purpose of establishing an in-house model tool for array modelling for CorPower Ocean. LÄS MER

  3. 2. Frequency Stability of Power Electronic Based Power System with 100% Renewable Energy.

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

    Författare :Abdullah Albalali; [2022]
    Nyckelord :energy storage; frequency control; synchronous generators; distributed power generation; virtual synchronous machine VSM ; PSCAD.; energilagringssystem; frekvenskontroll; synkrona generatorer; distribuerad kraftproduktion; virtuell synkron maskin; PSCAD.;

    Sammanfattning : The modern power system is aiming to progress away from conventional synchronous machine  based power generation towards converter dominated system that leads to extensively high penetration of renewable energy such as wind and PV. This transition of modern power system toward converter based renewable energy comes with new challenges as the conventional synchronous generation is being replaced by converter based power system (CBPS).

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

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

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

    Sammanfattning : 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).

  7. 5. Local energy system - Comparing direct current (LVDC) and alternating current (LVAC)

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Markus Alm; [2020]
    Nyckelord :Local energy system; LVDC; Technology and Engineering;

    Sammanfattning : This thesis uses a case study to compare the viability of using direct current instead of alternating current to supply power to 5 buildings in a local energy system (LES). The case study sought to show how using LVDC instead of LVAC could increase the effectiveness of solar panels (PV), batteries and interconnecting buildings into a local energy system (LES). LÄS MER
