  2. 1. System-Wide Impacts of Distributed Generation on Power System Operation : Data-Driven Approaches to Addressing the Challenges of Integrating Distributed Generation

    Author : Tin Rabuzin; Lars Nordström; Marjan Popov; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; data-driven modelling; distributed generation; dynamic equivalencing; islanding detection; reduced order modelling; datadriven modellering; detektion av ödrift; distribuerad generation; dynamisk modellering; reducerad ordningsmodellering; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Deployment of distributed generation (DG) is happening at an increasing rate driven by both the need for the reduction of humanity's carbon footprint and economic opportunities. The trend of increasing penetration levels of DG has also introduced interdependence between the responsibilities of system operators and the owners of the generating units. READ MORE

  6. 4. Nyquist Stability Analysis of a VSC-HVDC System with a Distributed Parameter DC-cable Model

    Author : Yujiao Song; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric power transmission; Nyquist stability analysis; VSC-HVDC system; Distributed parameter cable model; Small gain theorem.; Weak AC-grid;

    Abstract : Voltage source converter based high voltage direct current (VSC-HVDC) transmission systems have now been in operation since 1997 as it is a reliable and flexible method of power transmission. This thesis focuses on small signal dynamics of such systems, emphasizing stability properties. READ MORE

  7. 5. Thermal System Analysis : heat transfer in glass forming and fluid temperature-control systems

    Author : Karl Storck; Rolf Karlsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Thermal system analyses are often required, and conducted, in engineering problems in almost all engineering disciplines. The methods employed vary a great deal and must be specially adapted for each situation. Basically, two different methods are used, namely distributed modelling and lumped parameter modelling.
