1. 6. Learning by modeling energy systems

   Författare :Niclas Mattsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; time slices; GIS; negative emissions; experience curves; BECCS; climate targets; reanalysis; variable renewables; open source; energy system models;

   Sammanfattning : Meeting the 2°C climate target would likely require reducing carbon dioxide emissions from the global energy system to virtually zero within 50-100 years, and within 30-50 years for the 1.5°C target. LÄS MER

3. 7. Mathematical modelling and methodology for cost optimization of variable renewable electricity integration

   Författare :Caroline Granfeldt; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost optimization; variation management; variable renewable electricity; variable splitting; electricity system modelling; consensus algorithm; Lagrangian relaxation; wind power integration; long-term investment models;

   Sammanfattning : The global production of electricity contributes significantly to the release of carbon dioxide emissions. Therefore, a transformation of the electricity system is of vital importance in order to restrict global warming. LÄS MER

4. 8. Analysis and Forecasting of Utility-Scale Hybrid Wind and PV Power Parks

   Författare :Oskar Lindberg; David Lingfors; Joakim Munkhammar; Johan Arnqvist; Jakub Jurasz; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-located; probabilistic; forecasting; trading; wind; solar; variability; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

   Sammanfattning : The increasing share of wind and photovoltaic (PV) power in the electricity generation mix pose challenges in power system management due to their non-dispatchable and intermittent nature. Co-locating wind and PV parks, forming utility-scale hybrid power parks (HPPs), means that the sources can share grid connection, land, permitting procedures as well as operation and maintenance work.

5. 9. Energy Feedback and Demand Response Strategies : Exploring Household Engagement and Response Using a Mixed Methods Approach

   Författare :Anders Nilsson; Maria Malmström; Cajsa Bartusch; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy feedback; demand response; household energy consumption; energy efficiency and conservation; demand flexibility; smart grids; smart homes; Industrial Ecology; Industriell ekologi;

   Sammanfattning : Real-time energy feedback (EF) and demand response using dynamic pricing tariffs (DR) have been suggested as effective intervention strategies to meet the need for increased energy efficiency and demand flexibility in the residential sector. Although previous studies provide some empirical support for the effectiveness of EF and DR, evaluation approaches used in practical experiments and field trials commonly suffer from several methodological shortcomings, preventing deeper of knowledge on the potential and barriers for EF and DR to influence household energy consumption.

7. 10. Techno-economic assessment of wind energy for renewable hydrogen production in Sweden

   Författare :Shahid Hussain Siyal; Mark I Howells; Francesco F Nerini; Alberto Traverso; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

   Sammanfattning : Wind energy deployment has been growing globally. The resource is expected to play an important role in achieving economic and environmental sustainability - depending on its level of availability, economics, and policy.  Sweden has committed to have 20 TWh/year production of onshore wind energy in the national electricity sector by the year 2020.
