  1. 11. Microgrid Safety and Protection Strategies

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Aryudha Hartono; [2018]
    Keywords : IB-RES; grid-connected mode; islanded mode; short circuit; IED; directional zero and negative sequence current protection; unbalanced load flow; protection coordination; fault ride-through;

    Abstract : One of the challenging issues with the Microgrid is that the bidirectional power flow providedby the distributed generator (DG) which modify the fault current level. Furthermore, theinverter based-renewable energy source (IB-RES) limits the total fault current contributionto the grid due to its thermal capability. READ MORE

  4. 13. Dimensioning of a Residential Microgrid in Sweden

    University essay from KTH/Skolan för arkitektur och samhällsbyggnad (ABE)

    Author : Joakim Larsen; Tobias Tunestam; [2017]
    Keywords : ;

    Abstract : This project aims to evaluate through simulationsin Simulink whether an average power consuming, 4-personhousehold in Sweden, can be successfully supplied from amicrogrid system powered by solar panels. The goal is to achievea 48 V DC system and examine both its voltage stability and longterm power balance for stationary and transient conditions. READ MORE

  5. 14. The impacts of series compensated EHV lines on distance protection, and a proposed new mitigation solution

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Syed Arif Ullah Shah; [2017]
    Keywords : Series compensation; metal oxide varistor; voltage inversion; current inversion; sub-synchronous oscillation; quadrilateral characteristic distance relay; digital high-pass filter; Seriekompensation; metalloxidvaristor; spänningsinversion; ströminversion; subsynkron oscillation; fyrsidig karakteristiskt distansrelä; digitalt högpassfilter;

    Abstract : Series compensation is extensively applied to the transmission lines to increase the power transfer capability of transmission lines, reduce transmission losses, improve voltage profiles, and improve power oscillation damping and transient stability of power systems. But it modifies the apparent impedance of the transmission lines during fault conditions and might cause the distance protection of transmission lines to encounter directional discrimination issues and reach problems.

  6. 15. Dimensioning of a Residential Microgrid in Sweden

    University essay from KTH/Industriell ekologi

    Author : Joakim Larsen; Tobias Tunestam; [2017]
    Keywords : ;

    Abstract : This project aims to evaluate through simulationsin Simulink whether an average power consuming, 4-person household in Sweden, can be successfully supplied from a microgrid system powered by solar panels. The goal is to achievea 48 V DC system and examine both its voltage stability and long term power balance for stationary and transient conditions. READ MORE
