  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

  4. 2. Bandwidth Efficient IPTV Distribution : On Error Resilience and Fast Channel Change

    Author : Ulf Jennehag; Tingting Zhang; Stefan Pettersson; Nikolaus Färber; Mittuniversitetet; []

  6. 4. On Development Planning of Electricity Distribution Networks

    Author : Viktoria Neimane; KTH; []
    Keywords : Electric power systems; electricity distribution; planning; risk management; network optimization;

    Abstract : Future development of electric power systems must pursue anumber of different goals. The power system should beeconomically efficient, it should provide reliable energysupply and should not damage the environment. At the same time,operation and development of the system is influenced by avariety of uncertain and random factors. READ MORE
