  2. 1. Modeling, Control and Protection of Low-Voltage DC Microgrids

    Author : Daniel Salomonsson; Lennart Söder; Brian K. Johnsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circuit transient analysis; dc power systems; dispersed storage and generation; load modeling; power conversion; power distribution control; power distribution faults; power distribution protection; power electronics; Electric power engineering; Elkraftteknik;

    Abstract : Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. READ MORE

  4. 2. Planning Models for Single Wire Earth Return Power Distribution Networks

    Author : Geofrey Bakkabulindi; Lennart Söder; Mikael Amelin; Peiyuan Chen; KTH; []
    Keywords : Rural electrification; power distribution planning; Single Wire Earth Return; distribution power flow; power system modeling; SRA - Energy; SRA - Energi;

    Abstract : The high cost of grid extension to rural areas, often characterized by scattered communities with low load densities, requires the use of low cost electrification technologies to ensure economic viability. In Single Wire Earth Return (SWER) power distribution networks, the earth itself forms the current return path of the single phase system leading to significant cost savings on conductors, poles and poletop hardware compared to conventional systems.

  5. 3. Disruptive power : How distributed energy resources shape organizations and value logics in the future of electricity systems

    Author : Martin Warneryd; Eva Thorin; Ewa Wäckelgård; Dick Magnusson; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The electricity sector faces its largest transformation since its beginning about a century ago. Combinations of ageing electricity networks, removal of fossil supply sources and electrification of industry and transport sectors require vast efforts at all levels of society. READ MORE

  6. 4. On the Benefit of Harmonic Measurements in Power Systems

    Author : Erik Thunberg; KTH; []
    Keywords : Power Quality; Power System Harmonics; Harmonic Distortion; Harmonic Measurement; Harmonic Analysis; Power Distribution;

    Abstract : .... READ MORE

  7. 5. On the hosting capacity of distribution networks for solar power

    Author : Enock Mulenga; Math Bollen; Nicholas Etherden; Luis (Nando) Ochoa; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aleatory; distribution networks; epistemic; hosting capacity; overvoltage; solar power; stochastic; Electric Power Engineering; Elkraftteknik;

    Abstract : The future will bring changes in energy production and consumption that will affect the performance of electricity distribution networks. Electric vehicle charging will increase consumption; the installation of solar photovoltaic (PV) units will increase production. Both will change the energy flow and affect the power quality.
