2. 1. Power System Operation Planning and Wind Power Curtailment : Efficient Methods for Power System Scheduling and Integration Studies of Variable Renewable Energy

   Author : Elis Nycander; Lennart Söder; Mehrdad Ghandari; Robert Eriksson; Germán Morales-España; Benjamin Hobbs; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Variable renewable energy; wind power integration; production cost model; power-based unit commitment; wind power scenarios; Electrical Engineering; Elektro- och systemteknik;

   Abstract : To reduce carbon dioxide emissions, variable renewable energy (VRE) sources are replacing conventional fossil-based power plants for electricity generation. Due to the variability and uncertainty of weather dependent VRE sources, there can be situations when it is not possible to accommodate all the available VRE production, and VRE sources have to be curtailed.

4. 2. On optimal hydropower bidding in systems with wind power : Modeling the impact of wind power on power markets

   Author : Magnus Olsson; Lennart Söder; Stein-Erik Fleten; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydropower; wind power; stochastic modeling; optimization; Electric power engineering; Elkraftteknik;

   Abstract : The introduction of large amounts of wind power into power systems will increase the production uncertainties due to unforeseen wind power production variations. This will have a significant impact on the required balance management quantities. READ MORE

5. 3. 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

6. 4. Wind Power and Natural Disasters

   Author : Jon Olauson; Mikael Bergkvist; Stefan Ivanell; Uppsala universitet; []
   Keywords : Wind power; Natural disasters; Hybrid energy system; Meteorological model; Statistical model; Variability; Wind power integration;

   Abstract : Wind power can be related to natural disasters in several ways. This licentiate thesis gives some background and introduces four papers devoted to two aspects of this relation. The first section looks into how small-scale wind energy converters (WECs) could be used to generate power after a natural disaster. READ MORE

7. 5. Wind Power Integration in Power Systems with Transmission Bottlenecks

   Author : Julija Matevosyan; Lennart Söder; Olav Bjarte Fosso; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind power; hydro power; transmission bottlenecks; stochastic optimization; Electric power engineering; Elkraftteknik;

   Abstract : During the last two decades, the increase in electricity demand and environmental concern resulted in fast growth of power production from renewable sources. Wind power is one of the most efficient alternatives. READ MORE
