"Islanding operation of a community power grid with renewable energy sources and a large battery",
10th International 100% Renewable Energy Confernce (IRENEC 2020), Istanbul Turkey, 4. Jun. 2020, organized as online conference.

To support a concept of a decentralized power grid, the Bordesholm utility company (VBB) recently put a large battery into operation. It has a total capacity of 15 MWh and a maximum power of 15 MW, of which 10 MW are registered for primary control operation.
However, the large battery is also capable of serving as a grid former in island operation. This means that decentralised generators such as photovoltaic (PV) plants (approx. 1.4 MWpk) and a biomass plant (2.4 MW) present there can continue to operate and feed in power.
In a trial in November 2019, the whole community of Bordesholm was supplied with electricity for almost one hour only with the help of decentralised renewable sources and the battery. The transition from interconnected grid operation and the back-synchronisation took place seamlessly and without electricity customers being able to notice the transitions.
