  1. 1. Islanding Detection in Power Systems

    Author : Niklas Stråth; Industriell elektroteknik och automation; []

    Abstract : As the contribution of dispersed or distributed energy resources (DER) to the electric power production increases, the effects on the power system grow more important. As an example a critical situation may arise if protective relays trip a large part of the dispersed generation due to undervoltage at a short-circuit event. READ MORE

  2. 2. Converter Interfaced Distributed Generation - Grid Interconnection Issues

    Author : Fainan Magueed; Chalmers University of Technology; []
    Keywords : VSC; harmonics; LCL-filter; power quality; weak grid; voltage regulation; vector control; strong grid; distributed generation; intentional islanding; L-filter; voltage dips;

    Abstract : Distributed generation (DG) with a converter interface to the grid is found in many of the green power resources applications. In this thesis, the control of a voltage source converter (VSC), as the DG front end, is in focus regarding the power quality problems that could appear at the connection point. READ MORE

  3. 3. Synchrophasor Applications and their Vulnerability to Time Synchronization Impairment

    Author : Muhammad Shoaib Almas; Luigi Vanfretti; Mario Paolone; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Hardware-in-the-loop; phasor measurement units; real-time simulation; time synchronization; wide-area monitoring protection and control.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Recent years have seen the significance of utilizing time-synchronized, high resolution measurements from phasor measurement units (PMUs) to develop and implement wide-area monitoring, protection and control (WAMPAC) systems. WAMPAC systems aim to provide holistic view of the power system and enable detection and control of certain power system phenomena to enhance reliability and integrity of the grid. READ MORE
