2. 6. Control of Wave Energy Converters in arrays

   Author : Simon Thomas; Jens Engström; Mikael Eriksson; Jan Isberg; Erland Strömstedt; Axel Bochert; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Abstract : One way to lower the levelized cost of energy for wave power plants and paving so the way for commercial success, is to increase the power absorption by use of advanced control algorithms. This thesis investigates the influence of the generator inertia, the generator damping and the layout on power absorption and presents a new model free strategy of controlling wave energy converters.
