Rosetta Portal System Strength Heat Map - FAQ

The following questions are written from the viewpoint of a proponent intending to connect grid following inverter-based generation resources

What synchronous generation profile was used in the network studies to generate the heat map i.e. maximum or minimum fault levels?
The synchronous generation profile is identical to the one used when undertaking Preliminary Impact Assessments. This aligns with AEMO’s System Strength Impact Assessment guidelines which states that "Fault level calculations should consider an intact network, with the minimum number of synchronous machines online consistent with the system strength requirements"
As such, the heat map represents a minimum fault level scenario.

Is this system strength under normal conditions or contingency conditions (N-1)?
The heat map represents the system strength of a fully intact system under normal operating conditions.

Does this heat map take account of existing asynchronous, committed asynchronous and advanced asynchronous generators?
The heat map is a simplified representation of available fault levels and takes into account existing and committed asynchronous generators only.

Why are some locations showing both as high and low in system strength?
For example, for a 330/132 kV substation the 330 kV is indicating low system strength and 132 kV is indicating high system strength.
This difference arises due to assumptions around projects sizes at different voltage levels. For example, it is assumed a larger size project would connect at a higher voltage level: this leads to a large reduction in Available Fault Level. Conversely, it is assumed a smaller size project would connect at a lower voltage level: this leads to a smaller reduction in Available Fault Level. At locations where there is more than one voltage level, there may be more than one representation of system strength.

If a substation is indicating low system strength does this mean I cannot connect to that substation?
No, this does not mean you cannot connect to a location which is indicating low system strength.

If a substation is indicating high system strength does this mean there is no requirement for a Full Impact Assessment and/or system strength remediation?
No, this does not mean there is no requirement to undertake a Full Impact Assessment (FIA) and/or system strength remediation. Per NER requirements, a Preliminary Impact Assessment is required to be undertaken as part of a connection enquiry response. This in turn will determine the requirement to undertake a FIA.
The outcome of the FIA determines if system strength remediation is required.

There is medium to low system strength at the location I wish to connect my project but I believe this is sufficient under system normal and we can install a transfer trip scheme to disconnect from the grid for contingencies.
The requirement for a remediation strategy due to low system strength will be confirmed following a Full Impact Assessment. A transfer trip scheme may not be an acceptable remediation strategy for your circumstances.
Implementation of transfer trip schemes are subject to (but not limited to) AEMO agreement and approval during GPS negotiation and technical feasibility and/or any technical limitations discovered during functional and/or detailed design phases.
