  1. 21. Marginal cost pricing of electricity

    Författare :Göran Edsbäcker; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The discipline is economics and the phenomenon is the power system. The purpose of this system is to produce, transmit and consume electricity in such a way that the sum of consumers' and suppliers' surplus is maximized. This is accomplished by the means of marginal cost pricing. LÄS MER

  3. 22. Variation management for cost-efficient integration of variable renewable electricity

    Författare :Viktor Walter; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexibility measures; Energy storage; Energy system modelling; Renewable Energy;

    Sammanfattning : The aim of this work is to improve our understanding of how wind power and solar photovoltaics (PV) can be integrated into the electricity system in a cost-efficient manner. For this, a techno-economic cost-minimising model of the electricity system is used for a set of case studies. LÄS MER

  4. 23. Towards CO2 efficient centralised distribution

    Författare :Christofer Kohn; Maria Huge Brodin; Mats Abrahamsson; Alan McKinnon; Linköpings universitet; []
    Nyckelord :CO2 emissions; Centralised distribution; Structural change; Shipper; Transport; Trade-off; Interrelationship; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This dissertation treats a topic that has received increasing attention as of late, namely that of the environment and in particular increasing levels of CO2 emissions caused by transport. The aim of the dissertation is to explain how a shipper, through various measures, can reduce transport-related CO2 emissions when centralising a distribution system and how this affects the provision of cost efficient customer service.

  5. 24. Forest-Fuel Systems : Comparative Analyses in a Life Cycle Perspective

    Författare :Lisa Näslund Eriksson; Leif Gustavsson; Antti Asikainen; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest fuels; recovery systems; transportation; cost; primary energy use; CO2 emission; forest-fuel potential; life cycle perspective; Environmental engineering; Miljöteknik;

    Sammanfattning : Forest fuels can be recovered, stored and handled in several ways and these different ways have different implications for CO2 emissions. In this thesis, comparative analyses were made on different forest-fuel systems. The analyses focused on the recovery and transport systems. LÄS MER

  7. 25. The cost of free water : Water resources allocation and use in the Curu Valley, Ceará, northeast Brazil

    Författare :Karin Kemper; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Despite enormous investments in water storage infrastructure over past decades, the Curu Valley in the semi-arid state of Ceara, Northeast Brazil, is subject to increasing water stress. This study explains the current situation in the valley and explores institutional alternatives for the achievement of more efficient water resources allocation and use. LÄS MER
