1. 1. SECURITY OF SUPPLY DURING THE ENERGY TRANSITION:THE ROLE OF CAPACITY MECHANISMS

   Författare :Pradyumna Bhagwat; Mehrdad Ghandhari Alavijh; Margot P. C. Weijnen; Laurens J. De Vries; Reinier van der Veen; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Adequacy policy; capacity mechanisms; capacity market; investment; energy; agent-based modelling; EMLab-Generation; strategic reserve; security of supply; cross-border effects.; Economics; Nationalekonomi; Energy Technology; Energiteknik;

   Sammanfattning : The push for clean energy has caused a rapid growth of renewables in the electricity supply mix of the EU. Although one would assume that the impact of these technologies is entirely positive, recent research and experience indicate that there is reason for concern namely regarding the security of supply.

3. 2. Interruptible Load as an Ancillary Service in Deregulated Electricity Markets

   Författare :Anh Tuan Le; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reserve generation; least-cost planning.; interruptible load management; optimal power flow; ancillary services; deregulated electricity market; congestion management;

   Sammanfattning : Power companies world-wide have been restructuring their electric power systems from a vertically integrated entity to a deregulated, open-market environment. Previously, electric utilities usually sought to maximize the social welfare of the system with distributional equity as its main operational criterion. LÄS MER

4. 3. Interruptible Load Services in Deregulated Power Market

   Författare :Anh Tuan Le; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; congestion management; deregulated electricity market; ancillary services; optimal power flow; reserve generation; interruptible load management;

   Sammanfattning : Since the nineties decade, many electric utilities world-wide have been under restructuring from vertically integrated functioning to deregulated open-market system. In the erstwhile vertically integrated utilities, the system operator sought to maximize the social welfare with distributional equity (meeting the load at all time) as the main criteria, for the system as a whole.

5. 4. Interactions between carbon and power markets in transition

   Författare :Jörn Constantin Richstein; Mehrdad Ghandhari Alavijh; Margot P.C. Weijnen; Laurens J. de Vries; Remco Verzijlbergh; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EU ETS; carbon market; investment; electricity; agent-based modelling; EMLab-Generation; price floor; price ceiling; price corridor; market stabil- ity reserve; MSR; Energy Technology; Energiteknik; Economics; Nationalekonomi;

   Sammanfattning : In this research, several improvements to the European Union Emissions Trading System (EU ETS) were analysed. The EU ETS is a market for emission allowances and the European Union's main instrument for reducing greenhouse gas emissions (of which CO2 is the main component). 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
