  2. 1. Grid Connected Three-Level Converters : Studies for Wave Energy Conversion

    Author : Remya Krishna; Mats Leijon; Karin Thorburn; Uppsala universitet; []
    Keywords : Wave energy; power converters; control strategies; grid connection; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : This thesis presents an electrical system analysis of a wave energy converter (WEC) for the objective of grid connection. To transfer the enormous amount of power from waves to the load centers, efficient power electronic systems are essential. READ MORE

  4. 2. Off the grid

    Author : Mike Bode; Staffan Schmidt; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; artistic research; visual concepts; situated image; dialogue; ecological and political engagement; off grid living; housing estate suburbia; travel; self-definition; community; institution; isomorphic; lived third space;

    Abstract : Off the grid is an artistic research thesis which puts a Swedish housing estate in a video interview dialogue with homeowners in the Northeastern US through focusing on three topics: travel, self-definition, and community. Based on the situated, visual and conceptual image the project merges seemingly incompatible experiences: eight residents in Husby, an immigrant community outside Stockholm, and eight households not connected to the utility grid, in upstate areas of New England and New York State – and two artistic researchers at University of Gothenburg.

  5. 3. Grid-Connected Voltage Source Converter - Control Principles and Wind Energy Applications

    Author : Jan Svensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind turbine; voltage source converter; voltage angle control; frequency response; vector current control; grid-connected; forced-commutated; measurements;

    Abstract : The thesis focuses on a forced-commutated voltage source converter (VSC) connected to a grid in a wind energy application. The work consists of four parts. The first part addresses the type of electrical system which should be used in a wind turbine. READ MORE

  6. 4. Integration of Battery and Hydrogen Storage with a Grid-Connected Photovoltaic System in Buildings

    Author : Yang Zhang; Jinyue Yan; Jianzhong Wu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic; Grid; Building; Battery; Hydrogen Storage; Operation Strategy; Optimization; Energiteknik; Energy Technology;

    Abstract :     The integration of Photovoltaic (PV) with buildings changes the previous electricity consumers into prosumers. The reduced PV subsidies and the grid stable operation requirements are pushing prosumers from direct exportation to self-consumption of the produced electricity. READ MORE

  7. 5. Solar Variability Assessment and Grid Integration : Methodology Development and Case Studies

    Author : David Lingfors; Joakim Widén; Uwe Zimmermann; Eva Wäckelgård; Tobias Boström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar variability; Photovoltaics; Grid integration; GIS; Distributed generation; Engineering Science; Teknisk fysik;

    Abstract : During the 21st century there has been a tremendous increase in grid-connected photovoltaic (PV) capacity globally, due to falling prices and introduction of economic incentives. PV systems are in most cases small-scale, installed on residential dwellings, which means that the power production is widely distributed and close to the end-user of electricity. READ MORE
