The Project will investigate oscillatory issues in Australia’s national grid and develop tools to identify the root causes of instability and help identify potential solutions.  


Currently, AEMO does not proactively manage oscillatory stability. When oscillatory behaviour is observed, AEMO seeks to resolve it. AEMO has some tools and simulations which can help to address oscillatory stability. However, these tools are not very effective in identifying root causes of oscillatory stability.  


To address the immediate needs of the National Electricity Market (NEM), this project will employ several techniques and will develop various time-domain and frequency-domain analysis tools to identify the root causes of the low-frequency oscillations occurring in the NEM. To this end, time-domain simulations will be used to replicate similar oscillations using simple test systems such as Single-Machine Infinite-Bus (SMIB) and the NEM Power Systems Computer Aided Design (PSCAD) cases 


The Project will aim to: 

  • Reduce or remove barriers to renewable energy uptake by enabling AEMO and TNSPs to proactively identify and respond to oscillatory instability in the NEM. 
  • Increase security and stability in the NEM to support renewable generation growth. 
  • Increase skills, capacity, and knowledge relevant to integrating high penetrations of renewable energy technologies. 

Additional impact

The solutions developed will support grid operators, grid planners, and renewable energy developers to address the current and future small-signal stability issues caused by the increased penetration of renewable resources in the NEM
