    Keywords : Converter Design; Dual Active Bridge; Single Phase Shift Modulation; Extended Phase Shift Modulation; Efficiency Estimation; Konverterdesign; Dual Active Bridge; Single Fas Shift Modulation; Extended Phase Shift Modulation; Effektivitetsuppskattning;

    Abstract : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. READ MORE

  3. 8. Microgrid Protection Strategies for the Swedish Power System

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Zalak Shah; [2023]
    Keywords : Microgrid; Protection; three-phase fault; earth fault; Technology and Engineering;

    Abstract : This thesis mainly focuses on the protection strategies of microgrids for the Swedish power system in the medium voltage distribution system and specifically on the three-phase fault and earth faults protection strategies. For the analysis of both faults, different grid-connected, and islanding operations are simulated using DIgSILENT Power Factory. READ MORE

  4. 9. Fault current injection from Inverter Based Generation in the distribution grid : A case study of distribution grid on the Swedish island of Gotland

    Keywords : Distribution generator; Inverter-Based Distributed Generation; Inverter Based Generation; DFIG; PSCAD; Distribution grid; Overcurrent protection;

    Abstract : This work proposes recommendations for new guidelines for fault current injection on a distribution grid. These guidelines will help improve the transition towards renewable electrical energy generation. READ MORE

  5. 10. BGPcredit : A Blockchain-based System for Securing BGP

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

    Author : Yu Yang Liu; [2022]
    Keywords : blockchain; RPKI; consensus algorithm; border gateway protocol; security; blockchain; RPKI; konsensusalgoritm; border gateway-protokoll; säkerhet;

    Abstract : Due to the absence of appropriate security mechanisms, even the latest version of Board Gateway Protocol (BGP) is still highly vulnerable to malicious routing hijacking. The original problem is that BGP allows router to accept any BGP update message without any extra validation process. READ MORE
