  2. 16. Novel voltage source converter based HVDC transmission system for offshore wind farms

    Author : Stephan Meier; Hans-Peter Nee; Jan R. Svensson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric power engineering; Elkraftteknik;

    Abstract : Offshore wind farms have recently emerged as promising renewable energy sources. For increasing distances between offshore generation and onshore distribution grid, HVDC transmission systems based on voltage source converters can be a feasible and competitive solution. READ MORE

  4. 17. Simulation of Irregular Waves and Wave Induced Loads on Wind Power Plants in Shallow Water

    Author : Jenny Trumars; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave load; Non-linear wave models; ocean engineering; wind energy converter; perturbation theory; shallow water;

    Abstract : The essay gives a short introduction to waves and discusses the problem with non-linear waves in shallow water and how they effect an offshore wind energy converter. The focus is on the realisation of non-linear waves in the time domain from short-term statistics in the form of a variance density spectrum of the wave elevation. READ MORE

  5. 18. Modeling and analysis of offshore hybrid power parks

    Author : Erik Jonasson; Irina Temiz; Hans Bernhoff; Jon Olauson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : In the past decade, the global share of fossil-based electricity generation has decreased from 67% to 61% in favor of renewable alternatives. To achieve global goals, a continued extensive expansion of electricity generation from renewable energy sources is necessary. READ MORE

  6. 19. Grid Connection of Permanent Magnet Generator Based Renewable Energy Systems

    Author : Senad Apelfröjd; Sandra Eriksson; Frans Dijkhuizen; Uppsala universitet; []
