1. Evaluation of OPAL-RT Simulator through Simulation of Microgrid with High Penetration of DER
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/ElektricitetsläraSammanfattning : This thesis was written in collaboration with the department of electrical engineering at Uppsala University. It evaluates and tests the potentials and limitations of using the OPAL-RT simulator as a tool for designing and developing control strategies used in microgrids with a high penetration of distributed energy resources.

2. Local Voltage Control in Converter Based PV Generation
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : As the world is trying to rid itself of its dependence on fossil fuels, the need for renewable energy is rapidly increasing. In the power distribution network (DN), this takes the form of distributed generation (DG) from renewable sources, such as photovoltaic (PV) power production. LÄS MER
3. Oscillations in a complex sunspot: From theory to data
Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

4. Local voltage control in a low voltage grid with high photovoltaic penetration
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. LÄS MER
5. A Radical Restructuring of Development Aid : From Liberal Justice to “From each according to their ability, to each according to their needs” Assessing the Failures of Development Aid and Providing A New Normative Alternative
Kandidat-uppsats, Uppsala universitet/Statsvetenskapliga institutionenSammanfattning : In this paper I will argue for the need for a change of norms in the global governance system in regards to development aid. I argue that liberal norms of justice and distribution of wealth have a negative effect on development aid practices. This study is a normative political theory and the material researched is relevant literature sources. LÄS MER
