1. Grid reinforcing wind generation
Abstract : In this thesis, effects of some grid assisting possibilities that wind turbines could be equipped with, are investigated. The background is that concerns regarding the stability of the already existing power system in the presence of large wind farms have been risen. READ MORE

2. 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.

3. Wind Turbine Characterization by Voltage Source Converter Based Test Equipment
Abstract : In countries where wind power has become a relevant part of the total generated electrical power, transmission system operators (TSOs) have included in their Grid Codes specific technical requirements for interconnection of wind power plants. Some Grid Codes demand specific testing procedures in order to verify the fulfilment for their requirements. READ MORE

4. Grid Code Testing of Wind Turbines by Voltage Source Converter Based Test Equipment
Abstract : Wind energy is expected to play a crucial role in the energy mix in the future society with limited access to fossil fuels. Wind turbines with larger power rating are being installed every year, making possible to extract more energy from wind. READ MORE

5. Fault Behavior of Wind Turbines
Abstract : Synchronous generators have always been the dominant generation type in the grid. This fact affected both planning and operation of power systems. With the fast increase of wind power share in the grid in the last decade, the situation is changing. In some countries wind power represents already a consistent amount of the total generation.
