  1. 16. Design and construction of a bidirectional DC/DC converter

    University essay from Uppsala universitet/Elektricitetslära

    Author : Alexander Wallberg; [2019]
    Keywords : Converter; DCDC; Energy storage; Single-phase; Omvandlare; DCDC; Energilager; Single-phase;

    Abstract : A four quadrant general single-phase bi-directional DC/DC converter was designed and constructed for high effect systems. The target application for the DC/DC converter was to be used to transfer energy between different energy storages, a miniature DC power grid and the high voltage AC power city grid. READ MORE

  3. 17. Driftmodellering av saltvattenbatteri för kapning av effekttoppar : för en förskoleverksamhet i Uppsala

    University essay from SLU/Dept. of Energy and Technology

    Author : Hilda Andersson-Gran; Albin Björn; Sonja Winning; Judith Bösenecker; Gunnel Ersdotter; Madeleine Karlberg; David Norell Helmsjö; [2019]
    Keywords : effektbrist; programmering; energilager; elnät; PLC;

    Abstract : There is a power deficit in Uppsala's power grid. Municipal companies have an obligation to contribute with solutions to the power deficit. Skolfastigheter AB have therefore installed an environmentally friendly salt water battery in one of their properties. READ MORE

  4. 18. Photovoltaic Power Production and Energy Storage Systems in Low-Voltage Power Grids

    University essay from Linköpings universitet/Fordonssystem

    Author : Johan Häggblom; Jonathan Jerner; [2019]
    Keywords : electric power; power flow analysis; radial distribution system; low-voltage power grid; forward backward sweep method; photovoltaic power systems; energy storage systems; power factor; elkraft; effektflödesanalys; radiella distributionsnät; lågspänningselnät; forward backward sweep-metod; solcellsanläggningar; energilagringssystem; effektfaktor;

    Abstract : In recent years, photovoltaic (PV) power production have seen an increase and the PV power systems are often located in the distribution grids close to the consumers. Since the distributions grids rarely are designed for power production, investigation of its effects is needed. READ MORE

  5. 19. Optimisation of charging strategies and energy storage operation for a solar driven charging station

    University essay from KTH/Energiteknik

    Author : Jindan Gong; [2019]
    Keywords : Electric vehicle EV ; charging station; decentralized energy resources; linear programming; charging strategies; energy storage; energy system modelling; Elbilar; laddinfrastruktur; distribuerad elproduktion; linjärprogrammering; laddstrategier; energilager; förnybara energisystem;

    Abstract : The Swedish energy sector is undergoing transformational changes. Along with a rapid growth of renewables and a shift towards electromobility, the transformation is expected to bring challenges to the power system in terms of grid instability and capacity deficiency. READ MORE

  6. 20. State-of-the-art DC Current Interruption Concept using SiCMOSFETs

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

    Author : Georgios Papadopoulos; [2019]
    Keywords : ;

    Abstract : The transportation is in transition to the electrification era where the main source of energy for thevehicles is supplied by high energy propulsion batteries with voltages above 400 V. Currently the majority of the batteries are lithium-ion batteries and it is crucial to protect them from shortcircuits in order to ensure the safe operation in case of a vehicle crash or misuse of the vehicle.
