Abstract

The need to perform a full restart of the Queensland Electricity Network is rare but with the move to more Distributed Energy Resources (DER) the need to have new way to provide restart services is needed.

By utilising DER spread throughout the Queensland Electricity Network away from traditional generation sources, Distributed Restart Zones (DRZ) will be able to provide enough restart services to shorten the time it takes to completely restart the Queensland Electricity Network.

The ability of a DER such as solar, wind, or batteries to provide a restart service is limited to their ability to provide the service when needed. With DRZs, it should be possible to start with one DER in a location and grow the DRZ (Microgrid) to include several different DERs to be able to support each other.

The following research investigates the use of a Battery Energy Storage System (BESS) as the DER to provide the restart service by using a simulated model of a Grid Forming Inverter (GFMI), to create a DRZ modelled on a real-world situation. The response of the inverters is evaluated for suitability of a BESS to provide the restart service with initial results being mixed. Further investigate using a different GFMI control system is needed.
