1. 1. Techno-economic analysis and simulation of low temperature district heating networks

   University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Author : Ilia Iarkov; [2023]
   Keywords : Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

   Abstract : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. READ MORE

3. 2. Possibility for Positive Energy Retrofit in Borlänge

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Daniel Nay Myo Tun; Abideen Olaide Bakare; [2023]
   Keywords : ;

   Abstract : The built environment accounts for 40% of annual carbon dioxide (C02) emissions. Among the total emissions, building operations generate approximately 27% annually. Other than this, building materials, infrastructural materials, and construction (embodied carbon) contribute to an additional 13% annually [1]. READ MORE

4. 3. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Raúl Calvo García; Jose María Marín Arcos; [2023]
   Keywords : Flexible sector coupling FSC ; district heating DH ; thermal energy storage TES ; heat pump HP ; capacity optimization; dispatch optimization; open-access tools; Flexibel sektorkoppling; fjärrvärme; termisk energilagring; värmepump; kapacitetsoptimering; leveransoptimering; verktyg med öppen tillgång;

   Abstract : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.

5. 4. HEAT CONSUMPTION OPTIMIZATION IN 4TH GENERATION DISTRICT HEATING : Study on utilizing low temperature heat sources and heat stored in a house by varying indoor temperature

   University essay from Mälardalens universitet/Framtidens energi

   Author : Simon Karlsson; Farman Farman; [2023]
   Keywords : 4th Generation District Heating; Heat Pumps; Thermal Energy Storage; Optimization; Low Temperature Heat Sources; Thermal Inertia;

   Abstract : 4th generation district heating (4GDH) and varying the indoor temperature to store heat are both important concepts that can make it easier to implement more renewable energy and reduce costs of heating. This study looks at these concepts from a customer perspective using one building and looking at how energy can be stored and the performance of 4GDH. READ MORE

6. 5. Development of an integrated hybrid energy system model for cloud deployment

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Konrad Jackiewicz; [2023]
   Keywords : Heat Pump; Energy System Modelling; District Heating Systems; Smart Energy Systems; Technology and Engineering;

   Abstract : This research paper investigates the technical feasibility, system requirements, performance characteristics, and potential for optimization of an industrial heat pump in a district heating system, using the Modelon Impact platform. The study aims to provide a comprehensive understanding of the benefits and limitations of using cloud-based simulation platforms for the design and analysis of industrial energy systems. READ MORE
