1. 1. Utilizing Energy Storage Applied on Floating Wind Turbine Economics Using a Spot-Price Based Algorithm

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Jim Johansson; [2017]
   Keywords : wind power; wind energy; energy storage; spot-price; CAES; ORES; PHES; BESS; floating wind turbine; semi-submerged; spar-type; tension-leg; intermittent wind;

   Abstract : In this paper, a new algorithm for utilizing energy storage is proposed and applied on floating wind turbine economics. The proposed algorithm’s decision making on storing energy or selling electricity onto the grid is based on the electricity price, which makes it unique and different from similar algorithms.

4. 3. Fluid Structure Interaction Modeling of the Dynamic of a Semi Submerged Buoy

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Shatha Hameed Hajwal; Hamza Zeidan Nasser; [2013]
   Keywords : COMSOL Multiphysics; wave energy converter; Dynamic characteristic; Submerged body; Finite Element method FE ; SDOF; ALE.;

   Abstract : This thesis presents a study of buoy systems for wave’s energy by focusing on the development of a model in which modeling of a wave energy conversation is in operation. Throughout the thesis, the buoyancy and motion of the submerged body has been used to describe the wave-buoy interaction. READ MORE

5. 4. Fluid Structure Interaction Analysis of Planar Buoy

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Rakeshbhai Patel; Muhammad Adnan Hanif; Rajev Kumar Oad; [2011]
   Keywords : ALE; COMSOL Multiphysics; Finite element method; Fluid-structure interaction FSI ; Planar wave energy convertor; Two-phase flow;

   Abstract : Different types of wave energy convertors are being studied using the heave motion of floating bodies to generate electricity. In this thesis, we investigate the interaction of floating buoys from hydrodynamic point of view. READ MORE

6. 5. Fluid-Structure Interaction Analysis for Hydrodynamic Parameters in Semi-Submerged Axisymmetric Buoy

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Mohamed Salim Ramadan; Sorawan Saichua; [2010]
   Keywords : Added mass; Added damping; ALE; COMSOL Multiphysics; Fluid-structure interaction FSI ; Two-phase flow;

   Abstract : The dynamic heave responses of the semi-submerged axisymmetric buoy of two different geometries to the excitations equivalent to impulse excitation technique were represented by mechanical single-degree-of-freedom models. Founded on linear and 2-dimensional potential flow theory, the fluid-structure interactions were modeled and simulated with finite element approach. READ MORE
