  2. 2. Electric Energy Conversion Systems : Wave Energy and Hydropower

    Author : Karin Thorburn; Mats Leijon; Petra Lundström; Uppsala universitet; []
    Keywords : Engineering physics; Ocean wave power; renewable energy; linear generator; farm simulation; Teknisk fysik;

    Abstract : Electric energy conversion is an important issue in today's society as our daily lives largely depend on the supplies of energy. Two energy sources are studied for conversion in the present thesis, ocean waves and hydropower. The work focuses on the generator and the transmission of its output to the electric grid. READ MORE

  3. 3. Modelling and Advanced Control of Fully Coupled Wave Energy Converters Subject to Constraints: the Wave-to-wire Approach

    Author : Liguo Wang; Jan Isberg; Jørgen Hals Todalshaug; Uppsala universitet; []
    Keywords : Ocean wave energy; marine energy converter; wave energy converter; wave energy farm; potential flow theory; linear permanent magnet generator; control strategy; wave-to-wire approach; physical constraints; power generation control.; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Ocean wave energy is a promising renewable source to contribute to supplying the world’s energy demand. The Division of Electricity at Uppsala University is developing a technology to capture energy from ocean waves with a wave energy converter (WEC) consisting of a linear permanent magnet generator and a point absorber.

  4. 4. Modelling Wave Power by Equivalent Circuit Theory

    Author : Ling Hai; Mats Leijon; Rafael Waters; Yongliang Zhang; Uppsala universitet; []
    Keywords : Wave energy; hydrodynamics; electric circuit; electrical analogy; energy absorption; force; system modelling; Simulink; engineering science; renewable energy; Teknisk fysik med inriktning mot elektricitetslära; Engineering Science with specialization in Science of Electricity;

    Abstract : The motion of ocean waves can be captured and converted into usable electricity. This indicates that wave power has the potential to supply electricity to grids like wind or solar power. A point absorbing wave energy converter (WEC) system has been developed for power production at Uppsala University. READ MORE

  5. 5. Wind-wave interaction effects on offshore wind energy

    Author : Ali Al Sam; Strömningsteknik; []
    Keywords : wind-wave; swell; atmospheric boundary layer; marine atmospheric boundary layer; atmospheric turbulence; Large-eddy simulation; actuator line; wind sea; offshore technology; wind energy; wind turbine; aerodynamic;

    Abstract : This thesis is devoted to the investigation of the impacts of fast moving ocean surface waves on the aerodynamics of offshore wind turbines. The impacts of non-locally generated waves (swell) on the Marine Atmospheric BoundaryLayer (MABL) and thereby on offshore wind turbine aerodynamics are studied numerically by using Large Eddy Simulations and the Actuator Line Method.
