Operationalise Frequency Scanning
Frequency scanning has the potential to improve assessment throughout the connection process by providing insights into system interactions and control performance.
This workstream will collaborate with industry to identify, test and operationalise practical frequency scanning applications that can be embedded into standard connection assessment practices.
What is this workstream?
The workstream will explore how frequency scanning can be integrated into standard modelling and assessment workflows used by AEMO, Network Service Providers (NSPs), developers, consultants and Original Equipment Manufacturers (OEMs).
The aim is to ensure frequency scanning delivers actionable insights that support connection assessments and model validation activities, rather than remaining a specialist or ad hoc analysis tool.

Why is this work needed?
Connection assessments currently rely heavily on detailed and iterative studies studies to assess inverter-based resource (IBR) interactions and oscillatory behaviour. AEMO's research indicates frequency scanning may help identify potential issues earlier in the connection process, while using existing Electromagnetic Transient (EMT) models.
The Frequency Scanning workstream is focused on translating an existing AEMO-led frequency scanning initiative into a practical and scalable modelling approach that can be used across the National Electricity Market (NEM) connections process.

Objectives
The workstream aims to integrate frequency scanning into standard modelling and assessment workflows by:
- defining how stakeholders can produce, access and use frequency scan outputs
- establishing guidance on how results can be applied to connection assessments, plant performance studies, model validation and controller tuning
- supporting the routine use of frequency scanning to assess system interactions
- ensuring approaches remain practical, scalable and compatible with existing industry processes.
-
Approach
Stage 1: Identify and prioritise applications
Stage 1 will focus on identifying and testing potential frequency scanning applications with industry stakeholders. Expected outcomes include:
- a report outlining all applications explored during the workstream
- findings and technical direction from Focus Group workshops
- recommended pilot applications, including proposed approaches.
Stage 2: Prove and embed
Stage 2 will pilot selected applications on real-world projects before integrating successful approaches into standard modelling and assessment workflows used by AEMO, NSPs and proponents.
