  1. 1. Network reconfiguration for renewable generation maximization

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Gabriel Malmer; Lovisa Thorin; [2023]
    Keywords : distributed generation; hosting capacity; network reconfiguration; optimal power flow; power distribution; optimization; mixed-integer programming; Technology and Engineering;

    Abstract : Increasing the amount of renewable generation in distribution networks is a fundamental part of the energy transition. Multiple methods exist to increase the hosting capacity in a grid, to allow larger injections of generation and more efficiently utilize existing infrastructure before operational limits are breached.

  3. 2. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
    Keywords : high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

    Abstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE

  4. 3. Automatic overcurrent and leakage current sensing in multiple channel NMES systems

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

    Author : Malin Otter; Bashar Jamal Pati; [2023]
    Keywords : Neuromuscular Electrical Stimulation; Current monitoring; Overcurrent sensing; Leakage current sensing; Embedded systems; Instrumentation amplifier; Neuromuskulär elektrisk stimulering; Strömmätning; Överström detektering; Läckström detektering; Inbyggda system; Instrumentförstärkare;

    Abstract : This report presents the development, implementation, and testing of a current monitor system that is specifically developed for testing a neuromuscular electrical stimulation system (NMES). The NMES system, developed by KTH and its academic and industrial partners Karolinska institute and Matrix Muscle Support, incorporates advanced features aimed at preventing cardiovascular diseases.

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

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Farsad Mansori; [2022]
    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

  6. 5. Short-circuit current detection in electric vehicles

    University essay from Uppsala universitet/Signaler och system

    Author : Max Torbjörner; [2022]
    Keywords : Electric vehicles; Current measurement; Short-circuit; BEV Trucks; BJB;

    Abstract : In recent years the vehicle industries have been making much efforts to reduce the environmentalimpact by switching from the traditional combustion engine to electrification with battery driven electricvehicles. Producing electric trucks requires more batteries and operates at a higher voltage and currentthan commercial electric cars. READ MORE
