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

   Författare :Patrik Ollas; Caroline Markusson; Mattias Persson; Torbjörn Thiringer; Jan-Olof Dalenbäck; RISE; []
   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

4. 8. Global energy transitions : Renewable energy technology and non-renewable resources

   Författare :Simon Davidsson; Mikael Höök; Kjell Aleklett; Björn Sandén; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy transitions; natural resources; renewable energy; sustainable development; growth curves; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

   Sammanfattning : The global energy system is dominated by the use of fossil fuels. This system suffers from several problems, such as different environmental issues, while the long-term energy security is sometimes questioned. LÄS MER

5. 9. 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

7. 10. Cost-effective incentives for local electric utilities and industries in co-operation : modelling of technical measures

   Författare :Maria Andersson; Björn Karlsson; Curt Björk; Tomas Kåberger; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system; System cost; Electricity market; Co-operation; Demand-side management; Energy efficiency;

   Sammanfattning : In the Swedish electricity system there is a great potential for increasing the cost efficiency of the electricity use. However, today the economic incentives, offered for instance by existing electricity rates, are too weak to improve the use of the system. LÄS MER
