Huge Tesla Energy Storage Plus Wind Farm Equals Stabilized Power For Australia – Video
Naturally, such a big system needs to have an appropriate task for operation, and in this case, it will be support for the Hornsdale Wind Farm, which is operated by renewable energy provider Neoen near Jamestown.
The Hornsdale Wind Farm consists 99 3 MW turbines out of 105 planned (315 MW).
As the wind accounts for one-third of the total power mix within the South Australia state (2014-2015 data), there is a need to secure the grid with some reserves.
The Tesla ESS is expected to help solve power shortages, reduce intermittencies, and manage summertime peak load to improve the reliability of South Australia’s electrical infrastructure.
Here is interesting description of 2016 blackout that maybe could have be prevented with more energy storage:
“The AEMO report says three transmission lines were damaged during a September 28, 2016, storm. The storm produced tornadoes with wind speeds up to 260 kilometers (km) per hour. Two of the tornadoes almost simultaneously damaged a single circuit 275-kV transmission line and a double circuit 275-kV transmission line, roughly 170 km apart. The damage to those transmissions lines caused them to trip, which set off a serious of faults that resulted in six voltage dips on the grid in just two minutes.
“As the number of faults on the transmission network grew, nine wind farms in the mid-north of SA exhibited a sustained reduction in power as a protection feature activated,” the AEMO report explains. “For eight of these wind farms, the protection settings of their wind turbines allowed them to withstand a pre-set number of voltage dips within a two-minute period. Activation of this protection feature resulted in a significant sustained power reduction for these wind farms. A sustained generation reduction of 456 megawatts (MW) occurred over a period of less than seven seconds.”
As the wind farms failed, demand was increased for imported power flowing through the Heywood Interconnector, which allows for power flows between SA and Victoria. “Approximately 700 milliseconds (ms) after the reduction of output from the last of the wind farms, the flow on the Victoria–SA Heywood Interconnector reached such a level that it activated a special protection scheme that tripped the interconnector offline,” the report says.”
