On March 3, 2022, a serious power outage in Taiwan, happened. More than five million households and 500 industrial businesses were affected. Thanks to the SMA battery inverter, however, they were quickly back on the grid and supplied with power. The example clearly shows the importance of storage solutions in grids with an increasing share of renewable energies.<\/strong><\/p>\n

For the island nation of Taiwan, the power outage on March 3, 2022, was one of the most severe since the earthquake on September 21, 1999. A total of 5.49 million households \u2013 nearly 40 % of Taiwan \u2013 lost power. The semiconductor, optoelectronics, petrochemical, and steel industries all suffered disruptions. Financial and economic losses are estimated to be in the tens of billions of Taiwanese Dollars (TWD 10 billion equivalent to around \u20ac300 million).<\/p>\n

Chain reaction in the power grid<\/h2>\n

According to the power plant operator Taipower, on the morning of March 3, 2022, an equipment failure in the Hsinta Power Plant in Kaohsiung made every generator south of a certain extra high voltage substation in Tainan being disconnected from the power grid. Since Taiwan\u2019s entire power grid is interconnected, a malfunction at a single plant can lead to a chain reaction that has repercussions across the island. As a result, the power grid lost a third of its capacity.<\/p>\n

Maintaining grid stability in real time<\/h2>\n

With the help of the SMA Storage Solution including the battery inverter Sunny Central Storage<\/a>, the Taiwan Cement Corporation (TCC) secured frequency regulation backup auxiliary services and prevented worst scenarios by providing the maximum power of 5,000 kW. The SMA Storage Solution discharged to a maximum of 5,000 kW within 300 seconds.<\/p>\n

\"\"<\/a><\/p>\n

At 09:16:24 local time the AFC system reported an instant drop of the grid frequency down to 58.81 Hz. The SMA Sunny Central Storage 2900 discharged the maximum power of 5,000 kW within the shortest time. Only twelve seconds later, the grid frequency increased to 59.52 Hz, as while the discharge power came to decrease.<\/p>\n

Providing safe and stable grids with renewable energies<\/h2>\n

The average service performance measure (SPM) of this energy storage system always exceeded 99% since this storage power plant was in operation in March 2021. Within the high SPM data, the system has already become the highest operating rate and compliance rate of AFC energy storage systems in Taiwan.<\/p>\n\n\t\t
