A project to smooth the integration of renewable power on the grid using large and domestic-scale lithium-ion energy storage systems (ESS) has been launched in northern Germany.
German power firm Avacon and vehicle and energy storage OEM Rolls-Royce are exploring how battery storage combined with solar power can deliver grid stability services, such as frequency regulation.
The firms also aim to increase the rate of households consuming self-generated power.
The project is based on the concept of an ‘energy community’: an initiative that sees households store self-generated solar power in domestic-scale storage systems, with surplus energy fed through to a central, MW-scale ESS.
The project will use an MTU Solutions’ large-scale battery storage system. Its battery management system uses intelligent algorithms to control the interaction between domestic and large-scale battery storage.
MTU Solutions is a subsidiary of Rolls-Royce Royce Holding company.
It’s the second research project the firms are working on together. The other project is testing how battery storage can smooth moderate generation curves and balance PV connected energy on the grid.
