Due to the availability of suitable technologies, a number of battery based energy storage solutions have already been developed, implemented and deployed around the world. However, due to the large scale of penetration of renewable energy sources and unique characteristics of Australian power network, energy storage can also present specific solutions. Although the battery technologies are developing continuously and are becoming highly competitive options, their interactions in an ever growing complexity of microgrid applications need special attention. This paper highlights the opportunities in Australia and also explains the characteristic features of the mobile test system platform and the network structure, which aims to respond the industry's needs while providing training and research facilities.
