1. 6. Steady state analysis of HVDC grid in the North Sea with offshore wind power plants

   Författare :Kalid Yunus; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scheduled exchange power; NPV; transmission fee tariff; primary controller; ARIMA; external AC grid connection; secondary supervisory controller; meshed HVDC transmission grid; VSC HVDC; WPP;

   Sammanfattning : In this thesis, some of economical and technical aspects of expanding the HVDC (High Voltage Direct Current) transmission systems in the North Sea are studied at steady state. In the thesis, it is assumed that the expansion of the system is made by connecting WPPs (Wind Power Plants) to the system which is built for power exchange. LÄS MER

3. 7. Grid Integration and Impact of a Wave Power System

   Sammanfattning : Increasing energy consumption and concern for carbon emissions has boosted the demand for renewable energy production. The focus on renewable energy has gained much attention in wind, solar, hydro and wave power generations. Wave power has great potential due to its high energy density but there are challenges as well. LÄS MER

4. 8. Multilevel Inverter for Wave Power Conversion

   Författare :Remya Krishna; Uppsala universitet; []
   Nyckelord :;

   Sammanfattning : This thesis deals with the electrical system analysis of a Wave Energy Converter (WEC) for the objective of grid connection. The Linear Permanent Magnet Generator (LPMG) is modeled and validated with experimental results. The comparison studies establish that this model is useful for the subsequent system modeling and performance analysis. LÄS MER

5. 9. Novel voltage source converter based HVDC transmission system for offshore wind farms

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

   Sammanfattning : 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. LÄS MER

7. 10. Control strategies for various grid conditions in wave energy system

   Författare :Md Imran Ullah; Irina Temiz; Johan Forslund; Cecilia Boström; Deepak Elamalayil Soman; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The imperative goal of reducing carbon emissions and reaching net zero emissions in electricity generation has driven various renewable technologies, including wind energy, solar energy, and wave energy, among others. Even though wave energy is a recent addition to the already existing renewable energy technologies, it offers distinct advantages, such as a high power density and lower inter-annual variability compared to wind energy.
