1. Estimating Photovoltaic capacity using customs data : Model development of the tool NJORD and photovoltaics' characterization and impact on the African continent
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljöSammanfattning : Photovoltaics (PV) is one of the fastest growing power sources in the world in the last twenty years, being the most installed power source in almost half of the world's countries in 2020. Despite this, precise tracking of installations of PV does not exist in most of the world's markets due to PVs unique scalability and modularity. LÄS MER
2. Investigation of coarse-grid CFD approach for nuclear engineering application
Master-uppsats, KTH/FysikSammanfattning : In this thesis, an innovative coarse grid CFD approach is developed that aims toexploit the capabilities of sub-channel codes and CFD methods while overcoming theirlimitations. In the approach, a very coarse mesh is implemented in the CFD softwareOpenFOAM and a new wall treatment, based on the traditional concept of the wallfunction, is applied to the wall boundary conditions of the domain to take into accountthe low resolution of the grid which does not allow to effectively capture the effect of thesolid walls on the thermo-hydraulics of the flow.

3. Ride through Capability of medium-sized Gas Turbine Generators : Modelling and Simulation of Low Voltage Ride through Capability of Siemens Energy's medium-sized GTG and Low Voltage Ride through Grid Codes requirements at point of connection
Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : In order to reduce emissions and achieve sustainable energy systems, renewable energy is increasingly being integrated into the power grid. However, the integration of renewable energy into the grid poses several challenges, including maintaining a stable power supply under changing and unpredictable conditions. LÄS MER
4. Reactive power compensation of the electricity grid with large-scale offshore wind farms in Sweden : Technical capabilities, grid codes and economic incentives
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/ElektricitetsläraSammanfattning : Year 2040 the goal is to have a 100 % renewable Swedish energy system. Svenska kraftnät (Svk) predicts fully decommissioned nuclear power plants and an increased amount of connected wind power plants, especially offshore, year 2045. LÄS MER
5. Power Electronic Enhanced Distribution Transformer : Seamless Voltage Regulation with Extended Functionalities
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : On-load tap changers and static synchronous compensators (STATCOM) are the main components for voltage regulation and power quality optimization in the power system. STATCOMs are used in both industrial applications and utility to stabilize the grid and reduce downtime. LÄS MER
