1. 11. Effect of Surface roughness for Hydro Turbine Step-up Efficiency

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Ermias Beraki; [2018]
   Keywords : Hydropower; Surface roughness; Hydro Turbine; Step-up Efficiency; IEC 62097 standard; Prototype and Model;

   Abstract : The energy produced by the flow of water is known as hydropower. It is an easily accessible and available source of energy in large quantity in the form of, rivers, lakes, streams and runoffs around the world. Hydropower is dependent upon hydrological cycle hence; this beneficial characteristic of hydropower makes it a renewable source of energy. READ MORE

3. 12. Concept Study and Design ofFloating Offshore Wind TurbineSupport Structure

   University essay from KTH/Marina system

   Author : Markus Johannessen; [2018]
   Keywords : ;

   Abstract : There is a need for renewable energy sources that can replace the non-renewable energy sourcesthat we use today. This is on the agenda as one of the United Nations sustainable developmentgoals. Embracing new technologies is addressed as one of the ways of achieving aordable,reliable, sustainable and modern energy for all. READ MORE

4. 13. WAKE INDUCED POWER DEFICIT ANALYSIS ON WIND TURBINES IN FORESTED MODERATELY COMPLEX TERRAIN USING SCADA DATA

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Esma Öztürk; [2018]

5. 14. Airfoil Optimization Through Differential Evolution

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Eddie Nilsson; [2017]
   Keywords : Differential evolution; optimization; airfoil; wind turbine; Technology and Engineering;

   Abstract : This thesis presents the development of a numerical optimization algorithm for airfoils, and how it can be used in design of wind turbine blades. It was found that the developed algorithm successfully improves the goal parameters under given conditions and constraints. READ MORE

6. 15. Quantifying the Shadow Effect between Offshore Wind Farms with Idealized Mesoscale Models and Observed Wind Data

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : David Werner; [2016]
   Keywords : Shadow effect; offshore wakes; atmospheric stability; analog ensemble; wake forecasting; idealized mesoscale modeling; Weather Research Forecast WRF model; downscaling; North Sea; Princes Amalia; Egmond aan Zee;

   Abstract : Two post processing methods for quantifying the shadow effect of the offshore wind farm Princes Amalia (PA) onto Egmond aan Zee (OWEZ) wind farm are analyzed and benchmarked. The first method is the author’s proposed shadow effect determination method (SEDM), which quantifies an offshore wind farm’s shadow effect based on mesoscale WRF (Weather Research Forecast) idealized modeling and the observed frequency of the analyzed site’s wind conditions.
