  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

  4. 2. Modelling interactions between distributed energy technologies and the centralised electricity supply system

    Author : Joel Goop; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy systems modelling; variable renewables; power systems; distributed generation; demand response; electricity storage;

    Abstract : Renewable electricity generators, such as solar photovoltaics (PVs), and variation management technologies, such as battery storage and demand response (DR) systems, can be deployed in a distributed fashion, which can benefit the overall system. Such distributed energy technologies interact with and influence the centralised generation and transmission systems. READ MORE

  5. 3. System Studies and Simulations of Distributed Photovoltaics in Sweden

    Author : Joakim Widén; Ewa Wäckelgård; Brian Norton; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaics; Solar energy; Distributed generation; Load modelling; Time-use data; Markov chain; Power flow; Power system; Engineering physics; Teknisk fysik; Teknisk fysik; Engineering Science;

    Abstract : Grid-connected photovoltaic (PV) capacity is increasing worldwide, mainly due to extensive subsidy schemes for renewable electricity generation. A majority of newly installed systems are distributed small-scale systems located in distribution grids, often at residential customers. READ MORE

  6. 4. Optical modelling of conjugated polymers : from materials to devices

    Author : Nils-Krister Persson; Andy Monkman; Linköpings universitet; []
    Keywords : Spectroscopic ellipsomctry; optical modelling; organic solar cell; conjugated polymer; polyfluorene; polythiophene; copolymer; fullerene blend; photovoltaic device; dielectric function; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Measurements and modelling of theoretical properties of polymer-based photovoltaic devices, PPVDs, are the subjects of this thesis. Modelling refers both to modelling of materials, based on extraction of the dielectric function, and to modelling of devices by computer simulation of the optical electrical field inside PPVDs.
