21. Sizing and optimization of battery energy storage system for wind and solar power plant in a distribution grid : A case study on optimizing the size of the battery for peak shaving and ancillary services
Master-uppsats, Uppsala universitet/Byggteknik och byggd miljöSammanfattning : The increasing demand associated with the growing population poses a challenge to the operation of electricity systems worldwide. The electrification of the transport sector, accelerated electrification of industries and use of power demanding appliances in everyday life has increased the electricity demand significantly.

22. Renewable Microgrid : Design and modelling of a potential microgrid by analyzing the renewable resource at island Östergarnsholm to supply the inhabitants of Herrvik with electricity and fresh drinking water
Master-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : This project is aimed at developing a model for an off-grid microgrid by studying the wind and solar resource at Östergarnsholm, an island to the east of Gotland, Sweden. For the required consumption, a study and analysis of Herrvik’s local demand has been made which is a village close to the island and the possibility for implementing the microgrid to supply electricity to the inhabitants of Herrvik has been examined.

23. Energy storage technologies : A comparative techno-economic analysis with focus on economic value to the customer
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : As the global renewable energy penetration increases, energy storage technologies are being rapidly deployed to compensate for the intermittency and non-dispatchability of variable energy resources. Storage solutions play a crucial role in providing reliability and flexibility, but their growth is subject to a number of barriers. LÄS MER
24. Techno-economic Optimization for Large-Scale Power-to-methane Systems : Techno-economic modeling, design and optimization of a large scale 2.0 TWh/y solar-to-methane plant concept in Australia
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : Industrialized societies are built on the limited, extraordinary dense form of energy that are the fossil fuels: coal, oil, and gas, that became the core driver of the economic growth since the industrial revolution. While most emission pathways highlight the necessity to reach net zero emissions before 2050, there are numerous challenges to the displacement of fossil fuels by renewable energy systems (local conditions, intermittency, raw materials) and applications to the most polluting sectors such as transportation remain a major challenge.

25. Otrygghet på svenska redaktioner. Hat, arbetsbelastning eller utLASning? En översikt av svenska journalisters arbetsmiljö
Kandidat-uppsats, Umeå universitet/Institutionen för kultur- och medievetenskaperSammanfattning : Although the Nordic countries have consistently ranked at the top of the Press Freedom Index for the last decade they aren’t a monolith, untouched by the rise of populism, authoritarianism and its frequent attacks on the press; a scourge of democratic nations during the last vestiges of the 2010s. Nor have their media managed to escape the rocky seas of finding viable market solutions in an increasingly accelerating and expanding digital reality. LÄS MER
