  2. 16. Micro-grids supplied by renewable energy : Improving technical and social feasibility

    Author : Caroline Bastholm; Ewa Wäckelgård; Annette Henning; Frank Fiedler; Kirsten Ulsrud; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural electrification; Electricity access; Decentralized; Off-grid; Photovoltacs; PV-hybrid; Micro-grid; Multi-disciplinary; Sociotechnical; Engineering Science; Teknisk fysik; Energy and Built Environments;

    Abstract : Universal access to electricity stands high on the global agenda and is regarded as essential for positive development in sectors such as health care, education, poverty reduction, food production and climate change. Decentralized, off-grid electrification is deemed an important complement to centralized grid extension. READ MORE

  4. 17. Variability and variation management in a renewable electricity system -large-scale wind- and solar power deployment in Europe

    Author : Lina Reichenberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marginal cost of electricity; VRE; variability smoothing; solar power; power systems; renewable energy; wind power; energy systems modelling;

    Abstract : The large-scale deployment of wind and solar power poses challenges to the electricity system by introducing variability on the generation side. To handle these variations, variation management strategies can be employed to ensure that generation meets demand. READ MORE

  5. 18. The roles of transmission and distribution networks in integrating variable renewable electricity generation

    Author : Joel Goop; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electricity generation; demand-side management; energy systems modelling; power systems; variable renewables;

    Abstract : Emission reduction targets, together with other factors, such as security of supply, are driving the expansion of variable renewable energy sources for electricity generation, mainly solar and wind power. Trading across the transmission grid is an important measure to handle the increased variability and to balance supply with demand. READ MORE

  6. 19. Optimization of low-cost integration of wind and solar power in multi-node electricity systems: Mathematical modelling and dual solution approaches

    Author : Caroline Granfeldt; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variable renewable electricity; Lagrangian relaxation; ADMM; electricity system modelling; variable splitting; capacity expansion; cost optimization; variation management; consensus algorithm; subgradient algorithm;

    Abstract : The global production of electricity contributes significantly to the release of CO2 emissions. Therefore, a transformation of the electricity system is of vital importance in order to restrict global warming. READ MORE

  7. 20. Time-dependent climate impact of short rotation coppice willow–based systems for electricity and heat production

    Author : Niclas Ericsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Fossil fuel use and man-made land use change has increased carbon dioxide (CO₂) levels in the atmosphere, contributing to climate impacts such as global warming. Perennial crops such as short rotation coppice (SRC) willow have received attention because of their potential to sequester carbon (C) from the atmosphere and build up soil organic carbon stocks while producing biomass which can be used to generate energy services.
