1. 1. Hosting Capacity Methods Considering Complementarity between Solar and Wind Power : A Case Study on a Swedish Regional Grid

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Emma Andersson; Maja Abrahamsson Bolstad; [2023]
   Nyckelord :hosting capacity; hosting capacity methods; renewable power generation; power grid; power system analysis; complementarity; solar power; wind power; deterministic method; time series method;

   Sammanfattning : The demand for electrical power is growing due to factors such as population growth, urbanisation, and the transition from fossil fuels to renewable energy sources. To be able to keep up with the changes in electricity demand, the Swedish power grid must connect more renewable power generation, but also  increase its transmission capacity. LÄS MER

3. 2. On intermittency in the turbulent asymptotic suction boundary layer

   Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Edoardo Foschi; [2023]
   Nyckelord :Turbulence; turbulent boundary layer; intermittency; numerical simulation; DNS; tripping; suction;

   Sammanfattning : This thesis presents a series of direct numerical simulations (DNS) performed in order to understand the discrepancy in the literature regarding turbulent asymptotic suction boundary layers (TASBLs) at low Reynolds numbers. The hypothesis to be tested is that the main reason for higher turbulence intensities observed in experiments compared to DNS is that the latter exhibits intermittent patches of laminar flow, developing both temporally and spatially.

   Sammanfattning : This thesis explores the integration of hydrogen and battery energy storage systems as a means to enhance the management of wind and solar power in the pursuit of a greener grid. The objective of the study is to identify the potential benefits and challenges associated with hybrid energy storage systems (HESS) and their role in renewable energy integration. LÄS MER

7. 5. Towards Affordable Sodium-Ion Batteries : Mechanochemical Synthesis and Electrochemical Assessment of Iron-Based Fluorophosphate Cathode Material

   Master-uppsats, KTH/Materialvetenskap

   Författare :Ratna Juwita; [2023]
   Nyckelord :Sodium-ion batteries; electrical energy storage EES ; iron oxide; positive electrode; material characterization; electrochemical; discharge capacity.; Natriumjonbatterier; elektrisk energilagring EES ; järnoxid; positiv elektrod; materialkarakterisering; elektrokemisk; urladdningskapacitet;

   Sammanfattning : An urgent transformation from fossil fuels to cleaner energy sources to combat climate change has led to the utilization of renewable energies like solar, wind, and tidal power. However, the intermittency of these sources hinders their wider implementation. To address this, large-scale electrical energy storage (EES) systems are needed. LÄS MER
