1. 21. Möjligheter till ökad driftsäkerhet och kostnadseffektivitet i fjärrvärmenät : En simulerings- och optimeringsstudie på Kalmar Energi

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Carl Torstensson; Daniel Nordborg; [2019]
   Nyckelord :District Heating; NetSim; Simulation; Optimization; Bypass; Bottleneck; Differential pressure; DH; Fjärrvärme; Förbikoppling; Flaskhals; NetSim; Simulering; Optimering; Differenstryck;

   Sammanfattning : Since district heating is the most common way of space heatingin Sweden, continual improvements of theefficiency of production and distribution of district heating is crucial. The purposeof this report is therefore to, using Kalmar Energi as an example, study how the production and distribution of district heating is affected by introducing a bypass pipeat a critical point in the network, and to investigate howcost efficiency might be achieved.

3. 22. Models for Life Cycle Cost Estimation of Spare and Wear Parts for Urban Gondola Lift Systems : A Case Study

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

   Författare :András Borhidai; [2019]
   Nyckelord :urban gondola lift; cable car; life cycle cost calculation; spare part; wear part; reserve part;

   Sammanfattning : Urban gondola lift systems are becoming a regular sight rather than a rarity throughout the globe. Authors attribute their increasing popularity to factors such as environmental sustainability, operational reliability and cost efficiency compared to other right-of-way transit solutions. LÄS MER

4. 23. Demand-side flexibility in shopping centres - a case study on Väla shopping centre

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Pontus Svensson; Daniel Iggström; [2019]
   Nyckelord :demand-side flexibility; shopping centre; load control; battery energy storage system; peak power reduction; frequency regulation. ; Technology and Engineering;

   Sammanfattning : Sweden is heading towards an energy system with less nuclear power and more intermittent energy sources. Together with the coming electrification of the transport and industry sector, this challenges the future stability of the Swedish power system. LÄS MER

5. 24. Control of Aggregations of Electric Heaters to Provide Primary Reserves

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Syavash Kazemi Neira; [2019]
   Nyckelord :;

   Sammanfattning : This thesis investigates the potential of aggregations of Thermostatically ControlledLoads (TCLs) in the realm of Demand Response, particularly in the provision of primaryreserves, looking at control strategies for deployment in the Nordics.The work is carried out in collaboration with the Swedish/Norwegian start-up Tibberwho is operating as a digital energy supplier, trading renewable energy and oeringsmart home services to lower their customers' energy cost.

7. 25. Industrial Demand Response in the Primary Reserve Markets : A case study on Holmen’s Pulp and Paper Mill

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Federica Tomasini; [2019]
   Nyckelord :industrial demand response; pulp and paper industry; primary frequency control; stochastic optimization;

   Sammanfattning : This thesis stems from the interest of Holmen group to investigate the opportunitiesavailable for large electricity consumers in the Swedish primary reserve markets.The study performed focuses on one of Holmen's paper mill and it aims at identifyinga load inside the production process that is suitable for providing frequency containmentservices for the grid.
