Battery for reliability of supply

To avoid blackouts or to enable a black start it is useful for the power grid that parts of it can be disconnected, so-called “islanding”. A battery makes this possible because it can both store energy so that the generation can meet the demand and offer the services which the system needs to run separately from the rest of the power grid. These batteries can, for instance, be used in microgrids (see microgrid solution).

Components & enablers

  • A battery system based on NaNiCl2 batteries, provided with an optimum, smart grid control system and coping with the challenge of supporting multiple tasks.

State of the art in application and research

In TILOS, the battery system proposed supports both stand-alone and grid-connected operation, while proving its interoperability with the rest of micro grid components. Different operation strategies are investigated to define the optimum system integration.

In OSMOSE, a storage operator plans to install batteries in order to provide balancing services. By locating his solution in a network-constrained area, he could contribute at the same time to the management of congestion and by this reduce the costs for the society.

Technology Readiness Level

TRL 5 – development:

TILOS has tested a stand-alone operation, but results from this demo were not found. EMPOWER applied batteries in their microgrid, but did not research battery technology specifically.
