To assist in understanding the capability of smart meters, the South Australian Energy Minister formally requested AEMO to run a trial testing this capability. The trial tested, via a simulated response, the technical capabilities and communication protocols for smart meters to be used in such a way that may support power system security in rare circumstances. This report provides an overview of the technical capabilities for consideration in regulatory reforms.
This report shares AEMO’s preliminary findings on the behaviour of DER devices 'plugged' into the electricity grid during disturbances, and proposes the development of improved DER performance standards and DER dynamic models to facilitate secure, reliable, and affordable operation of a high DER energy system. This is an area of significant learning internationally, and understanding will evolve over time.
The Electric Power Research Institute (EPRI) undertook a supplementary independent, technical review, directionally supporting the findings in AEMO’s report (which was titled "DER Response to Disturbances" during development).
This report resulted from AEMO’s interest in effectively orchestrating the high levels of distributed energy resources (DER) in our networks to deliver a more productive and efficient power system. AEMO engaged the Electric Power Research Institute (EPRI) to undertake research about international experiences on:
- The best incentives and approaches to encourage active and dynamic market participation of DER.
- The development of tariffs, subsidies, connection requirements other mechanisms to encourage load shifting and active DER market participation. Further discussion on the key insights from this report can be found in the Renewable Integration Study (RIS) International Review.
AEMO engaged the Electric Power Research Institute (EPRI) to identify and explore international experiences in managing system-wide issues related to high penetrations of rooftop PV. There was particular interest in the implementation of dynamic PV feed-in management for small-scale rooftop systems (e.g.1-10 kW) and of distribution connected commercial systems (e.g. 30-100 kW). The review included details on implementation or trials of feed-in management, including:
- Technology selection (communication protocols, communication pathways, customer devices)
- Means of coordination, and
- Drivers for implementation.
