  2. 1. 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

  4. 2. 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

  5. 3. Efficient Simulation Methods of Large Power Systems with High Penetration of Renewable Energy Resources : Theory and Applications

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system simplification; power system reduction; power system aggregation; power system equivalencing; renewable energy resources; wind power modelling; storage allocation problem; spinning reserve determination; multi-area power system analyses; power system operation and planning; electricity market analysis.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Electrical energy is one of the most common forms of energy these days. Consequently, electric power system is an indispensable part of any society. READ MORE

  6. 4. On Distributed Balancing of Wind Power Forecast Deviations in Competitive Power Systems

    Author : Richard Scharff; Lennart Söder; Mikael Amelin; Gerard L. Doorman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; balancing; wind power integration; electricity market; wind power variations; wind power forecast errors;

    Abstract : Wind power generation does, on the one hand, contribute to a less polluting and more sustainable electric power generation mix. On the other hand, the uncertainty and the variability of the power output do challenge the operation of the power system: hourly variations in wind power generation are hardly predictable in a precise way.

  7. 5. System Studies and Simulations of Distributed Photovoltaics in Sweden

    Author : Joakim Widén; Ewa Wäckelgård; Brian Norton; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaics; Solar energy; Distributed generation; Load modelling; Time-use data; Markov chain; Power flow; Power system; Engineering physics; Teknisk fysik; Teknisk fysik; Engineering Science;

    Abstract : Grid-connected photovoltaic (PV) capacity is increasing worldwide, mainly due to extensive subsidy schemes for renewable electricity generation. A majority of newly installed systems are distributed small-scale systems located in distribution grids, often at residential customers. READ MORE
