Battery Storage Supporting Transmission Network

Industry News – November 24, 2021

TenneT and be.storaged are testing how they can use the flexibility potential of battery storage systems for the congestion management in the transmission grid.

Transmission system operator TenneT and EWE subsidiary be.storaged are collaborating on a pilot project that will test support for congestion management in the transmission network through the intelligent interaction of decentralised battery storage systems. As a provider of services relating to the construction and operation of battery storage systems be.storaged will bundle the flexibility potential of different battery storage systems via an agent-based energy management system and transfer it to the Equigy Crowd Balancing Platform. Depending on the respective load flow situation, this enables TenneT to test how the flexibility potential of battery storage systems can support congestion management.

The agent-based decentralized energy management system was developed by be.storaged in close cooperation with the Oldenburg OFFIS Institute for Computer Science. This allows battery storage to be used in more ways than just for limiting load peaks or increasing self-consumption of PV electricity. The local agents connect the individual battery storage systems to form a swarm and the pooled flexibility potential that is still available is transported from be.storaged to TenneT via the Equigy Crowd Balancing Platform. The pilot project would see an agent-based and a blockchain-based platform linked for the first time in order to give small-scale flexibility potentials efficient access to the system service markets, the project partners say.
