1. The social power grid : The role of institutions for decentralizing the electricity grid
Abstract : The world’s existing electricity grids face several challenges if they are to continue to provide a stable supply in the future. Aging electricity grids and the massive implementation of renewable sources require a different flexibility and robustness of future grids. READ MORE

2. Power-generation, Power-electronics and Power-systems issues of Power Converters for Photovoltaic Applications
Abstract : The thesis deals with issues related to solar energy systems, or more specifically, the electric systems of photovoltaic (PV) installations. Initially aspects of planning and estimating the performance of a PV-installation are considered. READ MORE

3. Modeling, Control and Protection of Low-Voltage DC Microgrids
Abstract : Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. READ MORE

4. Grid-forming wind power plants
Abstract : With growing concerns over climate change, the power system is witnessing an unprecedented growth in electricity generation from intermittent renewable energy sources (RES) such as wind and solar, which are commonly interfaced to the grid by power-electronic converters. However, increasing the penetration level of converter-interfaced generation units reduces the number of synchronous generators (SGs) in the grid that provide system services to support voltage and frequency, either inherently or through mandatory requirements and market products.

5. Modelling Wind Power for Grid Integration Studies
Abstract : When wind power and other intermittent renewable energy (IRE) sources begin to supply a significant part of the load, concerns are often raised about the inherent intermittency and unpredictability of these sources. In order to study the impact from higher IRE penetration levels on the power system, integration studies are regularly performed. READ MORE
