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

    Författare :Ferry Viawan; [2006]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
