  1. 21. 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

  3. 22. Analysis of load capacity in the low voltage network for different electricity load scenarios in Hammarby Sjöstad, Stockholm.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Laura Pomares Bleda; [2019]
    Keywords : ;

    Abstract : Sweden’s population is growing rapidly, especially in the southern areas like Stockholm, where the electricity consumption is higher. Therefore, more electricity will need to be transported from north to south, from where it is produced to where it is consumed. The current electric infrastructure, i.e. READ MORE

  4. 23. Charge into the Future Grid : Optimizing Batteries to Support the Future Low-Voltage Electrical Grid

    University essay from Linköpings universitet/Fordonssystem

    Author : Mergim Dushku; Julius Kokko Ekholm; [2019]
    Keywords : Optimization; Electric Vehicle; EV; Stationary Battery System; SBS; LV-grid; Electrical Grid; Peak Load; Voltage Variations; fmincon; Future Grid; Vehicle-to-Grid; Vehicle-to-Home; Photovoltaic; PV; Control Theory; Battery; Smart Charging; Nonlinear Programming;

    Abstract : The increase in electric vehicles and photovoltaic power production may introduce problems to the low-voltage distribution grid. With a higher number of electric vehicles, their accumulated charging power might breach the lowest allowed voltage level of the grid. READ MORE

  5. 24. Power peak reduction and control of automatic sliding doors

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Nicklas Norborg Persson; Per Josefsson; [2019]
    Keywords : Technology and Engineering;

    Abstract : When a sliding door is opened there is a sudden current peak that the electric network is subjected to. As a result of this it is difficult to design a power supply that operates the door with adequate performance while still maintaining a low power rating. READ MORE

  6. 25. Distributed energy resources in Sweden : The challenges faced by market actors that are developing business models

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Niklas Ersson; [2019]
    Keywords : Business Models; Electricity Market; Energy Efficiency; Renewable Energy.; Affärsmodeller; Elmarknad; Energieffektivitet; Förnybar energi.;

    Abstract : The electricity sector has traditionally been constructed for large scale generation and distribution from the high-voltage to the low-voltage network. Transition is however underway; intermittent power generation has become less expensive and nuclear power plants are set to close down. READ MORE
