11. Frequency response by wind farms in power systems with high wind power penetration
Abstract : The integration of variable speed wind turbines (VSWT) in power systems is increasing in order to reduce the emission of green house gases. This increase of power electronic converter interfaced generation causes a decrease of power system inertia, increasing the risk of load shedding and system frequency instability. READ MORE

12. Design and Control of Long-Pulse High-Power Klystron Modulators
Abstract : The European Spallation Source (ESS) is an under-construction material science research facility in Lund, Sweden, and will upon completion host the most powerful superconducting linear accelerator (linac) in the world. The ESS linac is powered by klystron modulators required to deliver long high-power pulses (pulse amplitude 115 kV/100 A, pulse length 3. READ MORE

13. On the Analysis of DC Network Dynamics of VSC-based HVDC Systems
Abstract : In this thesis, the dc network dynamics of VSC-HVDC systems is investigated through eigenvalue and frequency domain analysis. The eigenvalue analysis has been used to identify the factors that have an impact on the system stability. READ MORE
