1. 1. Jämförelse mellan energilagringstekniker, samt dimensionering av batterier och vätgaslagring i off-grid system med solceller : En mjuk multikriterieanalys, samt skapandet av ett dimensioneringsverktyg som tillämpas på befintliga verksamheter

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Vendela Stenholm; Sara Sjödin; [2023]
   Nyckelord :;

   Sammanfattning : Elsystemet måste vara i balans mellan den el som produceras och den el som konsumeras, i varje sekund året om, för att undvika effektbrist. Risken för obalans i elsystemet ökar dock, delvis på grund av en ökad andel förnybar och intermittent elproduktion. LÄS MER

3. 2. A Techno-Economic Case Study of the Implementation of Hydrogen Technology in Connection to a CHP Plant

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Kristina Häggström Wedding; Amanda Kander; [2023]
   Nyckelord :Hydrogen Technology; Electrolyzer; Fuel Cell; Ancillary Services; Electricity Markets; Power Balancing; Balancing Markets; Power to Gas; Power to Power; Combined Heat and Power; District Heat; Heat Utilization; Flexibility; Optimization; Technology and Engineering;

   Sammanfattning : With climate change as the main driving force, the energy system is currently undergoing changes. Both the share of renewable resources used to produce electricity and the overall electrification is increasing. A way to handle the resulting challenges from more intermittent electricity production is by the implementation hydrogen technology. LÄS MER

4. 3. Optimization of battery pack assembly of second life cells to reduce costs

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Akash Prasad Chowdry; [2022]
   Nyckelord :Batteries; second life cells; active cell balancing; lossless cell balancing; off-grid solar; solar home systems; Batterier; second life cells; aktiv cellbalansering; förlustfri cellbalansering; solceller utanför nätet; solcellssystem för hemmabruk.;

   Sammanfattning : Batteries account for 50% of the overall cost of solar home systems (SHS). The battery packs degrade over time and when they reach 70% state of health (SOH), the whole SHS is discarded. In the predominantly rural off-grid context, battery replacements are expensive and impractical. The customers are often dozens of km away from any sales point. LÄS MER

5. 4. Stochastic Optimization of Energy Prosumption Systems : A case study on energy balancing for self-sustainable societies

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

   Författare :Jim Allansson; [2022]
   Nyckelord :Stochastic Optimization; Energy Prosumption; SAA; Linear Programming; Stokastisk Optimering; Energi Prosumption; SAA; Linjärprogrammering;

   Sammanfattning : To achieve a sustainable future fossil electricity is being replaced with renewable, leading to higher uncertainties in electricity production. This has resulted in an incentive for consumers to produce, sell, and store their own electricity, hence becoming prosumers. LÄS MER

7. 5. System Study of the Techno-Economic Potential of a Hydrogen System : A case study of Power to Mobility and Power to Power hydrogen systems, stand-alone or integrated with a CHP

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Lina Forndal; Johanna Greiff; [2022]
   Nyckelord :green hydrogen; Power to Mobility; Power to Power; CHP;

   Sammanfattning : Green hydrogen produced with renewable electricity has gotten more attention during the last years and its different usage areas has been identified as an important part of the transition to a fossil free society. In this project the potential of a stand-alone hydrogen system and a hydrogen system integrated with a CHP, are investigated regarding technical and economic feasibility. LÄS MER
