  2. 1. Steady State Operation and Control of Power Distribution Systems in the Presence of Distributed Generation

    Author : Ferry Viawan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distance protection; stochastic assessment; voltage dip; line drop compensation; distribution systems; on-load tap changer; overcurrent protection; sensitive equipment; voltage dip immunity; voltage control; short circuit; reactive power control; pilot protection.; protection coordination; protection; Distributed Generation; losses;

    Abstract : In this thesis, the impact of distributed generation (DG) on steady state operation and control of power distribution systems is investigated. Over the last few years, a number of factors have led to an increased interest in DG schemes. DG is gaining more and more attention worldwide as an alternative to large-scale central generating stations. READ MORE

  7. 5. Maximizing the integration of wind power in distribution system

    Author : Shemsedin Nursebo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distribution system; integration issues of wind power; cost benefit analysis.; frequency of tap change; active management strategies;

    Abstract : The global installed capacity of wind power has shown a significant growth, from just 24 GW in 2001 to 283 GW in 2012. This trend is expected to continue for some years to come. Hence a significant amount of wind power needs to be connected to the electric power system. READ MORE
