1. 11. Electric cars for grid services : A system perspective study of V2G in a future energy system of Sweden and a local perspective study of a commercial car fleet

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

   Författare :Isak Søgaard Vallinder; Matilda Carlsson; [2022]
   Nyckelord :Smart charging; V2G; Ancillary services; Energy system modeling; Car Sharing; Sweden; Smart laddning; V2G; Stödtjänster; Energysystemmodellering; Bildelning; Sverige;

   Sammanfattning : One of the biggest challenges of today is to mitigate climate change and adjust our way of living in accordance with sustainability. To reduce the climate impact of the transport sector the electrification of the road transport sector is commonly seen as having a key role to play. LÄS MER

3. 12. Comprehensive Study of Meta-heuristic Algorithms for Optimal Sizing of BESS in Multi-energy syste

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

   Författare :Joakim Ginste; [2022]
   Nyckelord :BESS; Energy arbitrage; Firefly algorithm; Genetic algorithm; Peak shaving; BESS; energiarbitrage; Firefly algorithm; Genetic algorithm; spetslastutjämning;

   Sammanfattning : The question of finding the optimal size for battery energy storage systems (BESS) to be used for energy arbitrage and peak shaving has gained more and more interest in recent years. This is due to the increase in variability of electricity prices caused by the increase of renewable but also variable electricity production units in the electricity grid. LÄS MER

4. 13. Are Carnot Batteries an Alternative to Converting Coal Power Plants? : An open-sourced technoeconomic optimization approach for testing a new niche for Carnot Batteries.

   Master-uppsats, KTH/Energiteknik

   Författare :Vartan Jakob Ahrens Kayayan; [2022]
   Nyckelord :;

   Sammanfattning : As Europe transitions away from coal-fired power plants, there is an opportunity to reshape the electrical infrastructure. Many of the current plans are to make a switch to natural gas, another fossil fuel. Refurbishing existing power plants has several advantages. Components can be put to a new purpose. LÄS MER

5. 14. Estimating CO2 reductions from renewable energy sources : The impact of power system nonlinearities

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

   Författare :Kristoffer Berglund; [2022]
   Nyckelord :CO2 reduction; Dispatch model; Econometric model; Unit commitment; CO2-reduktion; ekonometriska modeller; produktionssimuleringsmodeller;

   Sammanfattning : Replacing conventional generation with renewable generation in power systems is essential for reducing CO2 emissions. It is important to know how effective renewables are in reducing CO2 emissions. Since CO2 reduction cannot be measured directly, different methods have been used to estimate reduction of CO2 emissions. LÄS MER

7. 15. Evaluation of mini-grid versus stand-alone projects: a tool for decision-making on household connections in last-mile rural electrification projects

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

   Författare :Irene Noguera Alonso; [2022]
   Nyckelord :Last-mile rural electrification; isolated from the network; polygeneration; modelling; network design; costs; mini-grid; stand-alone system; investment costs; Sista milen elektrifiering p˚a landsbygden; isolerad fr˚an n¨atverket; polygeneration; modellering; n¨atverksdesign; kostar; minin¨at; frist˚aende system; investeringskostnade;

   Sammanfattning : Electrification of isolated rural areas in developing countries is a key action for the total eradication of energy poverty. A growing number of authors argue that this electrification should be done with distributed energy systems that combine different renewable energy sources, rather than trying to reach these communities with grid extensions.
