2. 1. Combined Electrical Power Generation using Solar and Wind

   Author : Ingemar Mathiasson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave length bands; atmospheric transmittance; energy storage; Wind turbine; wind speed; quantum dots; electrical load.; extinction coefficient; silicon solar cell; solar cell;

   Abstract : The need for systems for renewable electrical power production is enormous worldwide.This applies to systems of varying size and capacity. From small systems for household purposes up to large systems for regional purposes. If possible, all systems should be linked in a common power grid. READ MORE

4. 2. Characterization and forecasting of wind conditions over the Baltic Sea

   Author : Christoffer Hallgren; Erik Sahlée; Julie Lundquist; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; forecasting; low-level jet; lidar; machine learning; mesoscale meteorology; numerical weather prediction; post-processing; reanalysis; sea breeze; turbulence; wind atlas; wind energy; wind power; Meteorologi; Meteorology;

   Abstract : To meet the increasing demand of sustainably produced electricity, the total number of installed wind turbines is rapidly increasing globally. Although onshore installations are dominating, offshore wind power is taking a greater share of the market every year. READ MORE

5. 3. Load and Risk Based Maintenance Management of Wind Turbines

   Author : Pramod Bangalore; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; wind energy.; supervisory control and data acquisition SCADA ; condition monitoring system CMS ; Artificial neural networks ANN ; maintenance strategy; maintenance planning; maintenance management; life cycle cost;

   Abstract : The cost of maintenance is a considerable part of the total life cycle cost in wind turbines, especially for offshore applications. Research has shown that some critical components account for most of the downtime in the wind turbines. READ MORE

6. 4. Load and risk based maintenance management of wind turbines

   Author : Pramod Bangalore; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; condition monitoring system CMS ; optimization; supervisory control and data acquisition SCADA ; maintenance planning; Artificial neural network ANN ; life cycle cost; maintenance management; maintenance strategy; wind energy.;

   Abstract : Wind power has proven to be an important source of renewable energy in the modern electric power systems. Low profit margins due to falling electricity prices and high maintenance costs, over the past few years, have led to a focus on research in the area of maintenance management of wind turbines.

7. 5. Modelling Wind Power for Grid Integration Studies

   Author : Jon Olauson; Mikael Bergkvist; Mats Leijon; Thomas Hamacher; Uppsala universitet; []
   Keywords : Wind power; Wind power modelling; Intermittent renewables; Variability; Integration or renewables; Reanalysis data; Power system studies;

   Abstract : When wind power and other intermittent renewable energy (IRE) sources begin to supply a significant part of the load, concerns are often raised about the inherent intermittency and unpredictability of these sources. In order to study the impact from higher IRE penetration levels on the power system, integration studies are regularly performed. READ MORE
