  1. 16. ASSESMENT OF WIND POWER FORECASTING ERROR FOR GOTLAND

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Simon Rengmyr; [2022]
    Keywords : Wind power forecasting; Machine learning; Numerical weather prediction;

    Abstract : When the wind blows and wind turbine generators harvests the kinetic energy and trans- forms it to electrical power, there is a need for predicting how much power that will be dispatched from the turbines. Even the most perfect computer model with high computa- tional power could not model the beauty of the forces of nature and we must accept some degree of forecasting error in the predicted power output due to the inherently stochastic patterns in the atmosphere.

  3. 17. Comparative Analysis of Energy-Based and Revenue-Based Availability Metrics of Wind Turbines

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : El Mehdi Ouchlou; [2022]
    Keywords : KPI; time-based availability; energy-based availability; revenue-based availability; wind turbine availability;

    Abstract : Different key performance indicators are used to assess various aspects of a wind turbine (performance, reliability, financial aspects…). Availability metrics mainly, time-based and energy-based availability are the main indicators used to monitor and evaluate turbine’s availability performance today. READ MORE

  4. 18. Damping of sub-synchronous control interactions with a STATCOM : Wind farms & series compensated power lines

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Leonardo Alvarez Urrutia; [2022]
    Keywords : Sub-Synchronous Control Interactions; Power Systems; STATCOM; Network Stability; Doubly-Fed Induction Generator; Impedance-Based Stability Analysis;

    Abstract : The power converter is one of the key components in power system applications such as high voltage direct current (HVDC) systems and the grid connection of intermittent sources such as wind and solar power. However, the increased penetration of converter-based generation introduces challenges, such as sub-synchronous interaction between the converter control system and the grid. READ MORE

  5. 19. Survey of Sweden’s installed wind turbine capacity and the country’s ability to handle future turbine decommissioning waste material

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Thanatorn Surawatsatien; [2022]
    Keywords : decommissioning; end-of-life wind turbine; blade material; decommissioned material;

    Abstract : The global market for wind energy is expanding rapidly, and in the last decade, Sweden has constructed thousands of wind turbines. The high installation pace suggests that a similarly rapid decommissioning rate is to be anticipated in the near future, notwithstanding the small number of turbines that have been retired thus far.

  6. 20. Short-term O&M Planning for Offshore Wind Energy

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Miguel de Matos e Sá; [2022]
    Keywords : Offshore wind energy; O M scheduling; optimization; wake effect; weather forecasts; risk analysis; Portugal; WindFloat Atlantic; Havsbaserad vindkraft; planering av drift och underhåll; optimering; wake effect; väderprognoser; riskanalys; Portugal; WindFloat Atlantic;

    Abstract : Significant breakthroughs are currently being achieved for Offshore Wind Energy (OWE), as offshore wind turbines are moving further away from the shore, benefitting from as vaster wind resource availability. On the other hand, the current trends of the OWE industry make new challenges arise. READ MORE
