DER integration and maintaining power system security

The following reports outline analysis on DER integration and maintaining power system security while levels of DER grow:

  • Chapter 7 of the 2020 Electricity Statement of Opportunities discusses the challenges arising across the NEM relating to managing voltage, system strength and inertia in low load conditions. It highlights opportunities for managing the power system during low demand periods including active DER management, load shifting, using frequency control services and transmission voltage control services, and actions to take to mitigate risk including introducing emergency back stop mechanisms and improving DER performance.
  • Quantifying the Minimum operational demand threshold in South Australia, investigating operational challenges that could emerge as South Australia moves to lower levels of operational demand due to increasing growth in distributed PV
  • Contributions to the Renewable Integration Study (RIS) Appendix A, with the development of case studies on DER integration challenges in South Australia.
  • Appendix A of the Final 2020 Power System Frequency Risk Review – Stage 1, which explores the impacts of distributed PV on the operation of emergency frequency control schemes in South Australia in periods with high distributed PV generation.

This work has been conducted in partnership with SA Power Networks, ElectraNet, and the South Australian Government.
