2. Long-term Voltage Stability in Power Systems - Alleviating the Impact of Generator Current Limiters
Abstract : The main issues in this dissertation are the behaviour of current limiters protecting synchronous generators, and the interactions that occur with other components in the power system during a voltage instability. The importance of these limiters for the voltage stability is shown both in the analysis of small models and in the simulations of larger networks. READ MORE

3. 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

5. Data-driven methods for real-time dynamic stability assessment and control
Abstract : Electric power systems are becoming increasingly complex to operate; a trend driven by an increased demand for electricity, large-scale integration of renewable energy resources, and new system components with power electronic interfaces. In this thesis, a new real-time monitoring and control tool that can support system operators to allow more efficient utilization of the transmission grid has been developed. READ MORE
