  1. 1. Dynamics of Energy Systems - Methods of analysing technology change

    Detta är en avhandling från Environmental and Energy Systems Studies, Lund university

    Författare :Lena Neij; [1999]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; evaluation; market transformation; PV modules; wind power; experience curves; air-distribution; lighting; vintage models; sustainable energy; renewable energy; energy efficiency; Energy; energy system; Energiforskning; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. LÄS MER

    Sammanfattning : This thesis is a study of how energy use and air pollution in Poland, Estonia, Latvia and Lithuania have been affected by the economic transition after 1989. It consists of six articles, which examine three different aspects of these changes. LÄS MER

  3. 3. National Energy System Modelling for Supporting Energy and Climate Policy Decision-making: The Case of Sweden

    Detta är en avhandling från Department of Environmental and Energy Systems Studies, Lund university

    Författare :Anna Krook-Riekkola; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik; climate policy; district heating; TIMES-Sweden; ancillary benefits; energy system models; cross-border trade; energy-economics; soft-linking.; CHP; system analysis;

    Sammanfattning : Energy system models can contribute in evaluating impacts of energy and climate policies. The process of working with energy system models assists the understanding of the quantita-tive relationships between different parts of the energy system and between different time periods, under various assumptions.

  4. 4. Energy Savings Using a Direct Current Distribution Network in a PV and Battery Equipped Residential Building

    Detta är en avhandling från Department of Environmental and Energy Systems Studies, Lund university

    Författare :Patrik Ollas; Caroline Markusson; Mattias Persson; Torbjörn Thiringer; Jan-Olof Dalenbäck; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Direct-Current Distribution; Residential Buildings; Battery Energy Storage System; Battery Modeling; Solar Photovoltaic System; System Performance; Energy Efficiency; Energy Savings; PV Utilisation;

    Sammanfattning : Energy from solar photovoltaic (PV) are generated as direct current (DC) and almost all of today’s electrical loads in residential buildings, household appliances and HVAC system (Heating Ventilation and Air-conditioning) are operated on DC. For a conventional alternating current (AC) distribution system this requires the need for multiple conversion steps before the final user-stage. LÄS MER

  5. 5. Is energy efficiency the forgotten key to successful energy policy? Investigating the Swedish case
