  2. 21. 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

  4. 22. Daylighting Systems : Development of Techniques for Optical Characterization and Performance Evaluation

    Author : Annica M. Nilsson; Arne Roos; Claes-Göran Granqvist; Marie-Claude Dubois; Michael Köhl; Uppsala universitet; []
    Keywords : Optical spectroscopy; integrating sphere; ray tracing; light scattering; window physics; Venetian blinds; core daylighting; optical characterization; Teknisk fysik; Engineering Science;

    Abstract : Successful integration of daylighting systems requires the ability to predict their performance for given climates. In this dissertation, a bottom-up approach is applied to evaluate the optical performance of a selection of daylighting systems. READ MORE

  5. 23. Reverse Logistics Systems : an Interorganisational Perspective, Focusing on Paper Recycling

    Author : Maria Huge-Brodin; Sten Wandel; Helén Anderson; Susanne Hertz; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reverse Logistics; Recycling; Paper; Interorganisational; Case studies;

    Abstract : The purpose of the study is to describe and analyse reverse logistics systems. The study is a qualitative case study, and the main case comprise three actors: a supplier of recycled paper; their customer, the paper mill, and the transport provider linking the customer and supplier. Reference cases are recycling electronics and recycling cars. READ MORE
