Design of an MMC-based grid-forming STATCOM with DC supercapacitors for energy storage KU Leuven
Driven by the energy transition, there is a massive phase-out of synchronous generators and an increase in power-electronic interfaced renewable resources. This increases the voltage and frequency fluctuations due to reduced dynamic reactive power support and system inertia. A possible technological solution to these challenges is the grid-forming STATCOM (GFM-STATCOM), where energy stored in DC-side supercapacitors provides the emulated inertia ...
Identification of mechanisms behind converter-related issues in power systems based on an overview of real-life events KU Leuven
Within modern power systems comprising both power-electronic converters and synchronous generators, a sufficiently high power quality and a stable operation can only be guaranteed if the fundamental mechanisms underlying converter-related issues can be thoroughly understood, properly identified and successfully mitigated. In particular, classifications are regarded as essential tools for the identification of converter-related instabilities and ...
AC/DC hybrid grid modelling enabling a high share of renewables: the Celtic interconnector use case KU Leuven
Evolving power systems, addressing stability needs before it is too late KU Leuven
Power systems are facing fundamental changes in their dynamics due to the introduction of power electronic devices, which are crucial for the energy transition. Adverse interactions have been increasingly reported worldwide indicating that power system's stability needs are not always met. We emphasize that stability at high frequencies should be ensured in a future-proof, scalable and efficient way by guaranteeing that new devices do not ...
Small-Signal Stability Analysis of an MMC-Based Bipolar HVDC Link in Grid-Forming Control Mode KU Leuven
The increased penetration of power electronic devices in the power system has led to power system stability concerns, which could in part be addressed by implementing grid-forming converter control strategies. At the same time, Voltage Source Converter High Voltage Direct Current (VSC HVDC) connections are moving towards bipolar configurations, which have two converters at each end of the link, connected in close electrical proximity at the AC ...
