1. Power-generation, Power-electronics and Power-systems issues of Power Converters for Photovoltaic Applications
Sammanfattning : 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. LÄS MER
2. Power Measurement Techniques for Nonsinusoidal Conditions. The Significance of Harmonics for the Measurement of Power and other AC quantities
Sammanfattning : The increased application of power electronics and other non-linear loads makes it necessary to re-evaluate the measuring techniques used in the power system, and the measuring problems these loads cause. An instrument utilising digital sampling techniques has been built and evaluated at the Swedish National Testing and Research Institute (SP). LÄS MER
3. Voltage Support of Transmission Grids Using Resources Located in the Underlying Lower Voltage Networks : Unlocking the Potential of Distributed Generation Reactive Power Capabilities
Sammanfattning : The path to sustainable, fossil-free future leads to inevitable energy transition towards renewable energy sources. A part of this transition includes replacement of conventional transmission system connected power plants with distributed renewables plants such as wind power. LÄS MER
