Project Details
Project Description
This project will enhance and commercialise Rezonance, a software platform that enables impedance-based stability analysis of encrypted PSCAD models (i.e. “black-box” inverter models). Rezonance addresses a growing challenge in grid connection and planning studies: the inability to assess control-driven instability or resonance risk when internal model logic is inaccessible.
Developed and validated in two prior ARENA-funded research projects, Rezonance reconstructs the frequency-domain response of IBR models and identifies oscillatory modes, weak-grid interactions, and damping shortfalls, without requiring source code or controller access. The software is delivered as a standalone, offline container suitable for secure use by consultants, TNSPs, and system operators.
This Stage 2 project will transition Rezonance from a validated prototype to a licensable, user-friendly product. Key activities include:
1) Developing advanced signal processing features for nonlinear model scanning
2) Integrating Q/Vm and P/θ analysis aligned with AEMO’s Grid-Forming Inverter Test Framework
3) Adding tuning and “what-if” scenario tools for inverter control design
4) Enabling wide-area multi-bus screening and risk ranking
5) Enhancing the graphical user interface and API for consultant/operator workflows
The project will be delivered by GridZync (a Monash University spinout) in collaboration with Monash, AEMO, a TNSP, and a consulting partner. Each partner will apply Rezonance to real-world models or scenarios to demonstrate its value in planning workflows.
Expected outcomes include:
1) Commercial readiness of the Rezonance tool (TRL 8, CRI 3)
2) Demonstrated use of impedance scanning in practical planning contexts
3) Increased visibility into IBR-driven risk without additional infrastructure
4) Knowledge-sharing outputs including technical case studies and tuning guides
The project directly supports ARENA’s strategic priority to optimise the transition to renewable electricity by addressing a critical stability visibility gap in connection and planning studies.
