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

    University dissertation from Stockholm : KTH

    Author : Daniel Salomonsson; KTH.; [2008]
    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; TECHNOLOGY Electrical engineering; electronics and photonics Electric power engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik 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

  3. 3. Power System Oscillations - Detection, Estimation and Control

    University dissertation from Department of Industrial Electrical Engineering and Automation, Lund Institute of Technology

    Author : Morten Hemmingsson; Lunds universitet.; Lund University.; [2003]

  5. 5. Planning Models for Single Wire Earth Return Power Distribution Networks

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Geofrey Bakkabulindi; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.
