21. Electrical System of a Wave Power Plant
Sammanfattning : Wave energy is a renewable energy source with a large potential to contribute to the world's electricity production. There exist several techniques to convert the energy in the ocean waves into electric energy. The wave energy converter presented in this thesis is based on a linear synchronous generator. LÄS MER
22. Multilevel Power Converters with Smart Control for Wave Energy Conversion
Sammanfattning : The main focus of this thesis is on the power electronic converter system challenges associated with the grid integration of variable-renewable-energy (VRE) sources like wave, marine current, tidal, wind, solar etc. Wave energy conversion with grid integration is used as the key reference, considering its high energy potential to support the future clean energy requirements and due the availability of a test facility at Uppsala University.

23. Energy from Ocean Waves : Full Scale Experimental Verification of a Wave Energy Converter
Sammanfattning : A wave energy converter has been constructed and its function and operational characteristics have been thoroughly investigated and published. The wave energy converter was installed in March of 2006 approximately two kilometers off the Swedish west coast in the proximity of the town Lysekil. LÄS MER
24. Hydrodynamic Modeling of the Energy Conversion from Ocean Waves to Electricity
Sammanfattning : Research within wave energy conversion has seen a large increase during the last years. Several concepts are now taking the final steps towards commercialization. LÄS MER
25. Wind Power - Added Value for Network Operation
Sammanfattning : This dissertation deals with the investigation on different value added properties of variable speed wind turbines (VSWT) that stem from the flexible controllability of converter interfaced wind turbines (WT). Improvements in voltage and transient stability of a nearby grid, small-signal stability improvement on the power system, frequency control support for the network operation, as well as thetechnical and the economic issues related to the reactive power ancillary service provision, are among the issues covered.
