6. Damping of sub-synchronous control interactions with a STATCOM : Wind farms & series compensated power lines
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : The power converter is one of the key components in power system applications such as high voltage direct current (HVDC) systems and the grid connection of intermittent sources such as wind and solar power. However, the increased penetration of converter-based generation introduces challenges, such as sub-synchronous interaction between the converter control system and the grid. READ MORE

8. Evaluation of a Minute Synthesis Irradiation Model for the Frequency Containment Reserve : Disturbance down-regulation market
University essay from Högskolan Dalarna/Institutionen för information och teknikAbstract : With the increase in energy demand, and therefore, in energy generation, new high voltage direct current export links and overseas connections of large amounts of power are being introduced. These new links are subject to possible malfunction or failures, which may causea substantial frequency increase in the power system. READ MORE

9. Magnetic and Dielectric Design of Auxiliary Power Supply for HVDC Applications : A high-frequency transformer with high power transfer capability and high voltage electrical insulation
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : It is anticipated that massive amounts of energy will be transferred long distances via High-Voltage Direct Current (HVDC) links in the future and the prospect of having meshed HVDC grids is envisioned, for example the European super grid. Such a power system would benefit greatly if HVDC circuit breakers could reliably clear faults within the HVDC network. READ MORE

10. Transient Waveform Clustering : Developing efficient data analytics toolchains applying unsupervised machine learning techniques on power quality events
University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Abstract : High Voltage Direct Current (HVDC) transmission systems appropriate for bulk power transfer to meet increasing power demands and ideal for interconnecting power systems with distant renewable sources of energy without any chances of loss synchronism, efficiency, and reliability. The main obstacle is however connected with the DC grid protection where the timely diagnosis of faults is critical to prevent any rapid built-up leading to failure of the power electronic devices.
