  2. 16. 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

  4. 17. Falls, fear of falling and falls self-efficacy among adults with multiple sclerosis

    Author : Elizabeth Peterson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Occupational therapy; multiple sclerosis; falls; fear of falling; falls self-efficacy; injury prevention;

    Abstract : Although falls are a major cause of morbidity and mortality among older adults and increasingly recognized as threat to the wellbeing of people living with chronic neurological conditions, fall prevention research involving people with multiple sclerosis (MS) is just emerging. The overall aim of this thesis was to generate new knowledge about fear of falling (FoF), fall-related injuries, and falls self-efficacy among middle aged and older adults with MS to inform development of occupational therapy interventions.

  5. 18. Spatio-temporal probabilistic forecasting of solar power, electricity consumption and net load

    Author : Dennis van der Meer; Joakim Widén; Jan Kloppenborg Møller; Uppsala universitet; []
    Keywords : ;

    Abstract : The increasing penetration of renewable energy sources into the electricity generating mix poses challenges to the operational performance of the power system. Similarly, the push for energy efficiency and demand response—i.e. READ MORE

    Abstract : The need to integrate the rapidly growing share of variable renewable energy sources in the power sector requires solutions that are capable of mitigating the intermittent nature of these sources. They are expected to constitute the backbone of the electricity generation system in the coming years in order to reach ambitious goals in terms of energy security and reduction of environmental impact.

  7. 20. Dynamic Thermal Rating for Improved Utilization of Wind Farm Export Systems : A Methodology for Improving Load Profile Estimation of Wind Farm Export Transformers

    Author : Zhongtian Li; Patrik Hilber; Tor Laneryd; Stefan Ivanell; Nguyen Nga; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic thermal rating; wake effect; turbine availability; transformer lifetime; transformer aging; dynamisk termisk klassificering; väckningseffekt; turbintillgänglighet; transformatorlivslängd; transformatoråldring; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The power system components connected to renewable energy sources, such as transformers, are often oversized and conservatively loaded. The design of transformers normally ignores the intermittent nature of the connected renewable energy sources (e.g. solar, wind). READ MORE
