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

    Författare :Bozena Guziana; Erik Dahlquist; Eva Thorin; Cecilia Mark-Herbert; Mälardalens högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  2. 2. Sustainability and development impacts of off-grid electrification in developing countries : An assessment of South Africa's rural electrification program

    Författare :Chukwuma Leonard Azimoh; Björn Karlsson; Boaventura Cuamba; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Off-grid electrification; sustainability; solar home system; hybrid mini-grid; renewable energy; technical challenges; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Previous studies have shown that provision of sustainable electricity supply to rural households is essential to bring development to off-grid populations. For this reason, most developing countries put large efforts into rural electrification programs to stimulate development and reduce poverty. LÄS MER

  3. 3. Boosting behavioral change in residential electricity consumption : demand response programs and feedback

    Författare :Cajsa Bartusch; Lars Wester; Monica Odlare; Thomas Porathe; Mikael Larsson; Kajsa Ellegård; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : As part of realizing national and European climate ambitions, it is imperative to bring about increased energy efficiency and consumption flexibility in the residential sector of the Swedish power market. In addition to governmental policy instruments to this end, market-based measures play an important role in making behavioral change in domestic electricity use happen. LÄS MER

  4. 4. From Passive to Active Electric Distribution Networks

    Författare :Javier Campillo; Erik Dahlquist; Wu Jianzhong; Mälardalens högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 5. Current harmonic modeling of aggregated electric vehicle loads in the low voltage grid

    Författare :Georgios Foskolos; Erik Dahlquist; Lennart Söder; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Vehicles; current harmonics; modeling; aggregation; power-exponential functions; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The proliferation of Electric Vehicles (EVs) poses new challenges for the Distribution System Operator (DSO). For example, the rectifiers that are used for charging EV batteries could significantly influence Power Quality (PQ), in terms of harmonic distortion. LÄS MER
