    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

  5. 23. Power control strategies for renewable energy systems : The inverter's role in future power systems

    Author : Sara Anttila; Cecilia Boström; Sandra Eriksson; Lena Max; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy systems; Grid-connection; Inverter; Power control; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Connecting more non-dispatchable renewable energy sources (RESs) will result in a higher power variability and a lower system inertia when the synchronous generators are replaced by inverter-connected RES. Inverter control can be divided in three categories: grid-following, grid-forming (GFM) and grid-supporting. READ MORE
