  1. 1. 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

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

    University essay from Linköpings universitet/Fordonssystem; 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

  3. 3. Optimal Day-Ahead Scheduling and Bidding Strategy of Risk-Averse Electric Vehicle Aggregator : A Case Study of the Nordic Energy and Frequency Containment Reserve Markets

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

    Author : Jacob Dalton; [2018]
    Keywords : ;

    Abstract : The Nordic synchronous grid is facing a number of challenges. The ongoingphaseout of synchronous generation coupled with increased penetration ofintermittent renewable generation is leading to reduced system inertia. READ MORE

  4. 4. Assessing the feasibility of implementing DC-microgrids in addition to USB-C and rooftop PV in households and offices: The Cases of Sweden and Spain

    University essay from KTH/Energiteknik

    Author : Miguel Igual Escriche; [2018]
    Keywords : ;

    Abstract : This Thesis’s frame is the feasibility of DC-microgrids at buildings environment. Nowadays, there is plenty of literature available regarding the benefits of implementing DC at buildings instead of AC as a means of optimizing photovoltaic generation PV on the grounds of minimizing conversion losses, with an overall energy saving of about 5-12% [1] [2].
