LT2029 Stability Tender — Grid-Forming BESS & SynCon
grid-forming BESS, Synchronous Condensers and 400 kV NGET connection
The challenge
As part of the LT2029 stability tenders, Field Energy required support to understand how different OEM grid-forming inverter solutions compared against each other before selecting a preferred bidder. Aurora also carried out separate LT2029 submission studies for synchronous condenser options.
What Aurora did
We carried out a side-by-side comparison of three OEM grid-forming inverter solutions, looking at performance under the LT2029 tests for fault contribution, inertia contribution and phase angle jump withstand. We also reviewed the quality of the PSCAD models, supporting documentation and the technical competence of each OEM to support the projects through detailed design.
In parallel, we completed two sets of classical synchronous condenser studies for LT2029 submissions at High Marnham and New Woolavington. The studies required optimisation of the design to maximise fault contribution while staying within the maximum headroom allocated by NGET.
