DER behaviour during disturbances
AEMO has been collecting and analysing data from a wide range of sources to understand DER behaviour in response to power system disturbances. Key findings can be found in:
- Analysing the behaviour of DER during disturbances as part of the 2019 Technical Integration of DER Report.
- Incident report for the Queensland-South Australia separation on 25 August 2018 (Appendix A1)
- Incident report for the Trip of No1 Busbar and No5 transformer at South Pine substation on 26 November 2019 (Appendix A2)
- Incident report for the New South Wales and Victoria Separation Event on 4 January 2020 (Section 8 and Appendix A3)
- Incident report – South Australia and Victoria Separation Event, 16 November 2019 (Section 7)
- Incident report – Victoria and South Australia Separation Event on 31 January 2020 (Section 9 and Appendix A1)
This information has improved AEMO’s ability to anticipate the behaviour of DER in various circumstances. It also contributes crucial input data to inform AEMO’s development of power system models that represent DER behaviour during disturbances, and has informed review of DER performance standards.
This work is being conducted in collaboration with the Australian Renewable Energy Agency (ARENA), Solar Analytics, Wattwatchers, the University of New South Wales, ElectraNet, TasNetworks and Energy Queensland. Key projects include:
- A collaboration between UNSW, ElectraNet, TasNetworks and AEMO, funded by ARENA, to conduct inverter bench testing. Further information on the project can be found here, and the bench testing results can be found here.
- A partnership with Solar Analytics and Wattwatchers on an ARENA funded project on Enhanced Reliability Through Short Time Resolution Data which will improve understanding of DER behaviour during voltage disturbances and resulting dynamic modelling.
- A collaboration with Energy Queensland, providing high speed measurements at various locations in their network.
These collaborations have provided key inputs to AEMO’s power system model development, and informed changes to DER performance standards.
