  2. 1. From Passive to Active Electric Distribution Networks

    Author : Javier Campillo; Erik Dahlquist; Wu Jianzhong; Mälardalens högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active distribution networks; smart grids; smart Meters; real-time pricing; demand-side management; electric vehicles; power systems; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Large penetration of distributed generation from variable renewable energy sources, increased consumption flexibility on the demand side and the electrification of transportation pose great challenges to existing and future electric distribution networks. This thesis studies the roles of several actors involved in electric distribution systems through electricity consumption data analysis and simulation models. READ MORE

  4. 2. Is the Swedish Environmental Goods and Services Industry Green? : Product and production perspectives

    Author : Bozena Guziana; Erik Dahlquist; Eva Thorin; Cecilia Mark-Herbert; Mälardalens högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology sector; Environmental goods and services; Clean technology; ‘Green’ business; ‘Green-green’ business; Production and product related environmental profile; miljöteknik sektor; miljöprodukter och miljötjänster; cleantech; ’gröna’ företag ’green’ business ; ’grön-gröna’ företag ’green-green’ business ; produktions- och produktrelaterad miljöprofil; Environmental engineering; Miljöteknik; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : In most business sectors environmental programs focus on direct, production-related environmental impacts. The design and development of products with reduced environmental impact is considered more difficult. The opposite applies in the environmental technology sector. READ MORE

  5. 3. Topographic Control of Groundwater Flow

    Author : Lars Marklund; Anders Wörman; Shulan Xu; Roy Haggerty; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Groundwater; Modeling; Topography; Spectral analysis; Fourier series; Exact solu-tions; Multi-scale; Grundvatten; Modellering; Topografi; Spektralanalys; Fourier serier; Analytisk lösning; Flerskalig; Hydrology; Hydrologi; Environmental engineering; Miljöteknik;

    Abstract : Gravity is the main driving force for groundwater flow, and both landscape topography and geology distribute the effects of gravity on groundwater flow.  The groundwater table defines the distribution of the potential energy of the water. READ MORE
