  1. 21. Microgrid Power Control Strategies: Enabling Distributed Energy Resources in Power Systems

    Författare :Jéssica Santos Döhler; Cecilia Boström; Janaína Gonçalves de Oliveira; Irina Temiz; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control strategies; energy storage system; islanding operation; microgrid; multifunctional inverter; ancillary services; unsymmetrical fault.;

    Sammanfattning : As the world continues to deal with the effects of climate change, the need for carbon neu-trality becomes increasingly urgent. To achieve this goal, many countries are exploring the potential of distributed energy resources to reduce their dependence on fossil fuels and transition to renewable sources of energy. LÄS MER

  3. 22. Adding Fuel to the Fire : North-South dynamics in the geographies of transport energy: the case of EU biofuels

    Författare :David Harnesk; LUCSUS; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy geography; geopolitics; territorialisation; climate change mitigation; transport; biofuels; agrofuels; European Union EU ; certification; sustainability criteria; sustainability science; energi; geografi; geopolitik; territorialisering; klimatomställning; transport; biodrivmedel; biobränsle; Europeiska Unionen; certifiering; hållbarhetskriterier; hållbarhetsvetenskap;

    Sammanfattning : Since the 2000s, the European Union (EU) has promoted biofuels for transport to achieve climate change mitigation, and rural development in the global South. In contrast, critiques have argued that biofuel promotion impedes more meaningful mitigation while also resulting in dispossession of land and loss of labour opportunities in the global South.

  4. 23. Charge and Energy Transport in Disordered Organic Semiconductors

    Författare :Hassan Abdalla; Martijn Kemerink; Ronald Österbacka; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Improvement of the performance of organic disordered semiconductors (OSC) is driven by the understanding   of the underlying charge transport mechanisms and systematic exploitation thereof. There exists a multitude of materials and material systems based on polymers and small molecules with promising performance for use in organic light emitting diodes, photovoltaics, organic field-effect transistors and thermoelectrics.

  5. 24. Land Use Conflicts between Agriculture and Energy Production : Systems Approaches to Allocate Potentials for Bioenergy and Agrophotovoltaics

    Författare :Daniel Ketzer; Peter Schlyter; Henrik Ny; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Renewable energies; Geographic Information Systems; Agrophotovoltaics; Participatory technology development; Responsible Research and Innovation; Physical Geography; naturgeografi;

    Sammanfattning : The developments towards a bio-based economy and a renewable energy-based power supply require thorough assessments of feedstocks and frameworks. In the past, political targets for increasing shares of renewable energies for combatting climate change have triggered direct land use changes (LUCs) and even indirect land use changes (iLUCs).

  7. 25. Organic Materials-based Electrochemical Flow Cells for Energy Applications

    Författare :Penghui Ding; Reverant Crispin; Viktor Gueskine; Mikhail Vagin; Brian Seger; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : To meet the 2015 Paris Agreement requirement of limiting global warming to 1.5 °C, the transition from fossil fuels to renewables (solar and wind) necessitates a rapid change of the energy landscape. LÄS MER
