Following a full set of site acceptance tests, the capabilities of this grid-connected microgrid shows promise for future microgrid applications. This white paper presents these results and discusses the future applications for the demonstrated technology.
The GESS, the first Australian system of its type and size, was installed in an industrial estate in northern Melbourne where it provides support to a local end-of-line feeder.
ABB in Australia provided integration technology and design for the AusNet GESS, while Samsung SDI took the role of battery supplier. The fully portable system is housed in six twenty-foot shipping containers and two transportable skids, allowing it to be positioned near to customers.
AusNet studied the effects that embedding the generation source close to the load would have on postponing network investment involved with upgrading feeder lines to support increased loads.
It also investigated:
- The capabilities of grid-connected microgrids to provide peak demand support
- The effect on local system quality and stability that the GESS will provide, such as power factor, voltage support, harmonics, flicker and negative sequence voltage
- The islanding capabilities of the GESS to improve system supply and stability in the case of larger network faults
This whitepaper presents the results of the AusNet GESS study and discusses future grid connected microgrids. Detailed results are available for download from the Microgrid Knowledge White Paper Library.
