4. 3. Spatio-temporal forecasting and optimization for integration of solar energy in urban energy systems

   Författare :Dennis van der Meer; Joakim Widén; Pierre Pinson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forecasting; photovoltaic; electricity use; net load; probabilistic; multivariate; optimization; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

   Sammanfattning : The increasing penetration of non-dispatchable renewable energy sources such as photovoltaic (PV) systems in the electricity generating mix poses challenges to the operational performance of the power system. On the demand side, advanced schemes that increase the flexibility of customer loads and the increase in electrification are set to noticeably alter electricity demand. LÄS MER

5. 4. Hydrological Seasonal Forecasting

   Författare :Kean Foster; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrological seasonal forecasting; seasonal forecast; spring flood; multi-model ensembles; teleconnection patterns; modelling chain;

   Sammanfattning : In Sweden, almost half of the electricity produced comes from hydropower. However, the amount of water in the reservoir catchments is not evenly distributed throughout the year. During the colder months, precipitation usually falls as snow and accumulates into a snowpack. LÄS MER

7. 5. Improved mapping of steel recycling from an industrial perspective

   Författare :Alicia Gauffin; Anders Tilliander; Ichiro Daigo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling rate; lifetime; steel scrap; scrap reserve; dynamic material flow modelling; environmental analysis; greenhouse gas emissions; energy; alloy content; forecasting; backcasting; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : The results from this study show that it is possible to obtain data series on the steel scrap collection based on mass balance model on the crude steel production figures by steelmaking reactor type and additional knowledge on process metallurgy as well as information on inputs and outputs into the reactors with an area correlation coefficient of 0,91 compared to data obtained from trade statistics. Furthermore, the study shows that based on a new method it is possible to calculate the time duration of mass flows on a continuous basis. LÄS MER
