  2. 21. Quantitative vulnerability analysis of electric power networks

    Author : Åke J. Holmgren; Torbjörn Thedéen; Lars-Göran Mattsson; Terje Aven; KTH; []
    Keywords : Safety Analysis; vulnerability; homeland security; risk analysis; network; electric power system; blackout; power law; statistical analysis; graph theory; branching process; game theory; Säkerhetsanalys; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Disturbances in the supply of electric power can have serious implications for everyday life as well as for national (homeland) security. A power outage can be initiated by natural disasters, adverse weather, technical failures, human errors, sabotage, terrorism, and acts of war. READ MORE

  4. 22. From data collection to electric grid performance : How can data analytics support asset management decisions for an efficient transition toward smart grids?

    Author : Sylvie Evelyne Koziel; Patrik Hilber; Per Westerlund; Ebrahim Shayesteh; Iordanis Koutsopoulos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asset management; data analytics; data management; distribution system operators; electrical power grid; machine learning; real-world datasets; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Physical asset management in the electric power sector encompasses the scheduling of the maintenance and replacement of grid components, as well as decisions about investments in new components. Data plays a crucial role in these decisions. READ MORE

  6. 24. 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

  7. 25. On Incentives affecting Risk and Asset Management of Power Distribution

    Author : Carl Johan Wallnerström; Rajeev Thottappillil; Patrik Hilber; Ulf Sandberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asset management; correlation studies; incentives; investment planning; maintenance planning; power distribution; reliability analysis; risk management; statistical validation; tariff regulation; vulnerability analysis; weather states; Electric power engineering; Elkraftteknik; Mathematical statistics; Matematisk statistik; Industrial engineering and economy; Industriell teknik och ekonomi;

    Abstract : The introduction of performance based tariff regulations along with higher media and political pressure have increased the need for well-performed risk and asset management applied to electric power distribution systems (DS), which is an infrastructure considered as a natural monopoly. Compared to other technical systems, DS have special characteristics which are important to consider. READ MORE
