Title of Experiment | Pure simulation test: frequency stability assessment of renewable-based systems using SI and FFR support from converter-based resources |
Research Infrastructure | DTU |
Experiment Realisation | Simulation: IEEE 9 bus system with converter-based resources (CBR) (wind, PV, battery, etc.) as replacements for SGs is implemented in digital real-time simulator. CBRs are equipped with SI/FFR control based of specifications of grid codes. Different disturbances such as load increase or SG trip are carried out to evaluate ROCOF and frequency deviation of the system with SI/FFR in services. A delay can be added to emulate the communication latency. Comparison of SI/FFR based on different grid codes for frequency stability improvement. The interaction of SI/FFR of converters with SGs is also considered. |
Experiment Setup (concrete lab equipment) | Pure simulation in RTDS |
Experimental Design and Justification | The pure simulation aims to evaluation frequency stability with SI and FFR support from converter-based resources in terms of ROCOF and frequency deviation. It can be a reference for a comparison with the PHiL simulation |
Precision of equipment and measurement uncertainty | PB5-based RTDS racks Time step of simulation: 50-60 µs |
Storage of experiment data | Data is collected on run time of simulation in CSV extension file and stored at a local PC |
