EUAA Submission: AEMO Review Of Technical Requirements For Connections – Addendum To Draft Report
Emily Wood | May 23, 2023
‘…The EUAA understands that AEMO is concerned with potential positive feedback loop contingency events, whereby a disturbance happens in the electricity network which triggers some loads to trip, further exacerbating the disturbance and causing additional loads to trip. We further understand through consultation with AEMO, that AEMO are specifically concerned about inverter-based loads (IBL) where they believe the above risk is far more likely to occur, and in areas where there are numerous IBL that could potentially trip.
The proposed rule change as we understand it will require all consumers that meet the proposed new load definitions to perform system strength impact assessments (modelling), requiring engagement of Power Systems Engineers. Our understanding is that many traditional industrial loads will be captured by the proposed new load definitions and be required to undertake modelling. This would impose yet another energy related cost onto Australian industries in an environment where cost increases are all too frequent.
It is the EUAA’s view that a targeted rule change aimed at the particular risks identified by AEMO in relation to IBL is a better option than a rule change that captures many industrial loads which have proven over time to be of no issue…’
