Grid code compliance
One of the Medium Voltage (MV) skids had a different DC/AC configuration, introducing additional modelling complexity that had to be accurately represented and consistently captured across all studies.
Grid code compliance
One of the Medium Voltage (MV) skids had a different DC/AC configuration, introducing additional modelling complexity that had to be accurately represented and consistently captured across all studies. While the DC side maintained the same number of batteries, the AC active power was curtailed.
Our team pro-actively identified all the input data and OEM RMS and EMT models inconsistency to be able to replicate the plant model accurately to show NESO Grid code compliance. Multiple meetings were held and followed up on every technical detail until a satisfied response and new compatible models were supplied to us.
The plant model was successfully updated and all the required studies were completed to ensure full compliance for – PQ capability, G5/5 , P28. The project is ongoing with the team now finalizing the NESO RMS and EMT dynamic studies.
The Minety BESS project comprises two phases: Phase 1, an existing 99.8 MW installation, and Phase 2, a proposed 49.9 MW extension connecting to the 132 kV network.
The OEM RMS and EMT models provided to the customer for plant-level model development exhibited significant performance and stability issues.
Let's Collaborate deliver resilient, future ready solutions.
