2. 1. Wind power wake modelling : Development and application of an actuator disc method for industrial utilization

   Author : Nikolaos Simisiroglou; Stefan Ivanell; Thorsten Lutz; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wind power; Offshore wind farm; Wakes; Actuator Disc Method ACD ; Computational Fluid Dynamics CFD ; Reynolds Average Navier–Stokes RANS ; WindSim; PHOENICS;

   Abstract : As a wind turbine extracts energy from the wind it creates a region downstream where the wind velocity is decreased and the urbulence intensity is increased, this region is commonly called the wake region. Today’s wind farms include a large number of wind turbines position in tight layouts. READ MORE

4. 2. Expansion Governance of the Integrated North Seas Offshore Grid

   Author : João Gorenstein Dedecca; Paulien M. Herder; Rudi A. Hakvoort; Amineh Ghorbani; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Union; expansion planning; governance; HVDC; myopic optimization; North Seas; offshore grid; offshore wind; simulation;

   Abstract : The expansion of offshore power transmission and generation in the North Seas of Europe is accelerating rapidly. This is due to several drivers, including the decarbonization and reform of the European power system, and innovations in offshore wind and high-voltage direct current transmission. READ MORE

5. 3. 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

6. 4. A Novel Oil-immersed Medium Frequency Transformer for Offshore HVDC Wind Farms

   Author : Mohammad Kharezy; Per Olof Hedekvist; Yuriu Serdyuk; Thomas Hammarström; Karsten Backhaus; RISE; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; prototype design methodology; finite element analysis; HVDC insulation design; medium frequency transformer; Wind energy; DC-DC power converters;

   Abstract : In this project, a design of an oil type medium frequency transformer for offshore wind farm applications is proposed. The design is intended for applications when series coupling of the output of the DC/DC converters of the wind turbine on their secondary side is done to achieve a cost-effective high voltage solution for collecting energy from offshore wind parks.

7. 5. Broadening Horizons : The FMECA-NETEP model, offshore wind farms and the permit application process

   Author : John Ohlson; Bo Carlsson; Håkan Thorstensson; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cumulative impact; risk; offshore wind farm OWF ; FMECA; kumulativa effekter; risk; havsbaserad vindkraft; Miljövetenskap; Environmental Science;

   Abstract : Abstract  The permit application process for offshore wind farms (OWF) in Sweden conceivably requires a comprehensive and transparent complement within risk management. The NETEP framework (covering risks concerning navigation, economics, technology, environment and politics), based on a futures planning mechanism (STEEP) has consequently been brought forward as a structure for the application of FMECA (Failure Mode, Effects, and Criticality Analysis) methodology to the permit application process of the Swedish offshore wind farm sector.
