  1. 1. 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).

  3. 2. Design of a Future Residential DC Microgrid

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

    Författare :Viktor Andersson; Max Gugolz; [2022]
    Nyckelord :Grid control; grid converter; DC microgrid; buck-boost; PV; MPPT; P O; ESS; SOC;

    Sammanfattning : In the search for environmentally friendly methods to implement renewable energy in the power system residential microgrids have been proposed and proven. The direct current (DC) microgrid topology is a promising implementation of a microgrid system due to the increasing amount of DC-operated loads and production units expected in the near future.

  4. 3. Evaluation of DC Fault Current in Grid Connected Converters in HVDC Stations

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Soham SinhaRoy; [2022]
    Nyckelord :Symmetrical monopole; HVDC LCC and VSC; CTL; MMC; Converter reactor; DC smoothing reactor; DC pole-to-pole fault; Peak factor; SCC; SCR; PSCAD EMTDC;

    Sammanfattning : The main circuit equipment in an HVDC station must be rated for continuous operation as well as for stresses during ground faults and other short circuits. The component impedances are thus selected for proper operation during both continuous operation and short circuit events. LÄS MER

  5. 4. Power Electronic Enhanced Distribution Transformer : Seamless Voltage Regulation with Extended Functionalities

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

    Författare :Nils Johansson; [2022]
    Nyckelord :Hybrid distribution transformer; Power converters; Voltage control; Hybrid power system; Reactive power; Hybrid distrubitionstransformator; Effektomvandlare; Spänningskontroll; Hybrida elnät; Reaktiv effekt;

    Sammanfattning : On-load tap changers and static synchronous compensators (STATCOM) are the main components for voltage regulation and power quality optimization in the power system. STATCOMs are used in both industrial applications and utility to stabilize the grid and reduce downtime. LÄS MER

  7. 5. Model verification and common mode current analysis of grid connected three phase two level converters

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

    Författare :Simon Lindvall; Richard Haraldsson; [2021]
    Nyckelord :active filter; EMC; EMI; converter; common mode; differential mode; shunt active filter; parasitic elements; Technology and Engineering;

    Sammanfattning : In this Master’s thesis an in-depth model of a shunt active filter for high frequency analysis is constructed. The purpose is to enable analysis of higher frequency behavior reaching 1MHz. Using the high frequency model, common mode currents can be simulated. LÄS MER
