  2. 21. Spatially explicit electrification modelling insights : Applications, benefits, limitations and an open tool for geospatial electrification modelling

    Author : Dimitris Mentis; Mark I. Howells; Sonia Yeh; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

    Abstract : Developing countries confront the challenge of generating more electricity to meet demands in a sustainable manner. According to the World Bank’s 2015 Global Tracking Framework, roughly 15% of world population (or 1.1 billion people) lack access to electricity, and many more rely on poor quality electricity supplies.

  4. 22. Mathematical modelling and methodology for cost optimization of variable renewable electricity integration

    Author : Caroline Granfeldt; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost optimization; variation management; variable renewable electricity; variable splitting; electricity system modelling; consensus algorithm; Lagrangian relaxation; wind power integration; long-term investment models;

    Abstract : The global production of electricity contributes significantly to the release of carbon dioxide emissions. Therefore, a transformation of the electricity system is of vital importance in order to restrict global warming. READ MORE

  5. 23. Forecasting of Icing Related Wind Energy Production Losses : Probabilistic and Machine Learning Approaches

    Author : Jennie Molinder; Anna Sjöblom; Heiner Körnich; Hans Bergström; Erik Nilsson; Sue Ellen Haupt; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wind energy; Icing on wind turbines; Machine learning; Probabilistic forecasting; Meteorologi; Meteorology;

    Abstract : Icing on wind turbine blades causes significant production losses for wind energy in cold climate. Next-day forecasts of these production losses are crucial for the power balance in the electrical grid and for the trading process, but they are uncertain due to lack of understanding of, and simplifications, in the modelling chain.

  6. 24. Wind turbines over a hilly terrain: performance and wake evolution

    Author : Ann Hyvärinen; P. Henrik Alfredsson; Antonio Segalini; Leonardo P. Chamorro; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; wind turbines; complex terrain; wind-tunnel measurements; Strömningsmekanik; vindturbiner; komplex terräng; vindtunnelmätningar; Engineering Mechanics; Teknisk mekanik;

    Abstract : The aim of this licentiate thesis is to investigate wind-turbines placed in a complex-terrain environment. This is done by studying the flow around small-scale wind-turbine models placed over a landscape model with hills, and by comparing the results with corresponding data obtained over a flat terrain model.

  7. 25. Modern Thermal Power Plants - Aspects on Modelling and Evaluation

    Author : Klas Jonshagen; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; T-Q diagram; Combined cycle; heat- and mass-balance modelling; carbon capture; CO2;

    Abstract : The European Union (EU) has laid down very clear objectives for the reduction of greenhouse gases in the hope that it will prevent or mitigate climate change. Political incentives are used to make the power industry adopt changes in order to reach these EU targets. READ MORE
