  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. Planning and Operation of Large Amounts of Wind Power in a Distribution System

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

    Abstract : The global installed capacity of wind power has shown a significant growth, from 24 GW in 2001 to 370 GW in 2014. The trend shows that an increasing capacity of wind power is being connected to the electric power system. READ MORE

  5. 3. Voltage Stability Simulations Using Detailed Models Based on Field Measurements

    Author : Daniel Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacity limits; field measurements; dynamic load models; on-load tap-changer control system; voltage stability; simulations;

    Abstract : This dissertation deals with voltage stability simulations, including dynamic load models, on-load tap-changer control system dynamics and generator reactive power output capacity limits. The simulations are based on sequential solving of ordinary load flow cases augmented with dynamic models. READ MORE

  6. 4. 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

  7. 5. Efficient Integration of Distributed Generation in Electricity Distribution Networks - Voltage Control and Network Design

    Author : Ingmar Leisse; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coordinated Voltage Control; Distributed Generation; Electricity meter; PV; Wind Power; Distribution Network;

    Abstract : Distributed generation (DG), i.e. generation connected to the low and medium voltage distribution network (DN), has been increasing a lot during recent years. Thus the traditional assumption of a unidirectional power flow and a voltage decrease along the distribution feeders is no longer valid in all operation conditions. READ MORE
