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. 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

5. 4. 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

6. 5. Design and Evaluation of Heavy Electric Vehicle DC Charging Overcurrent Protection

   University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

   Author : Daniel Buvarp; [2022]
   Keywords : DC charging; overcurrent protection; circuit breaker; simulation; semiconductor;

   Abstract : The vehicle industry must reduce emissions to lessen their environmental impact. Using electric motors for propulsion and batteries for energy storage decreases the pollution and greenhouse gases emitted by heavy commercial vehicles such as trucks and buses. READ MORE
