Tesla's 100 MW/129 MW·h lithium battery storage power station was put into operation in South Australia. And on 14th December 2017 and 18th January 2018

Tesla storage battery participated in grid frequency regulation automatically after unit tripping accident in the Victorian Loy Yang power station. This paper firstly analyzes the physical and economic reasons that Tesla storage battery was integrated into Australian power grid. Then the structure and control strategy of battery is introduced. Furthermore

operational status of power grid is introduced after the commission and operation of Tesla energy storage. Also

grid related energy storage technical standards and evaluation hierarchy are suggested. Storage's leverage effect which is applied to partially replace coal-fired generator's primary frequency regulation ability is proposed. New type of ancillary service is developed and profitable making business mode of storage is explored. All the above proposals are lessons which enlighten energy storage and storage-grid integration technologies in China.
