German energy supplier Avacon and Rolls-Royce are collaborating to test the contribution of battery storage and PV systems to power grid stability.
Based on a field test, the aim is to show how energy communities, PV systems and mtu battery storage – developed by Rolls-Royce – can be intelligently linked to contribute to an efficient energy supply and to stabilise the energy system.
The project is based on the concept of an energy community: local households store electricity they generate themselves from PV systems in home storage units, and surplus energy is also fed into the central mtu large-scale battery storage system.
Speaking at the commissioning ceremony, Lukas Köhler of Rolls-Royce Power Systems said: “We are delighted to be working with Avacon again.
“The intelligent linking of our mtu battery storage system with PV systems and home storage systems, which is to be tested in the project, makes an important contribution to both the energy transition and grid stabilisation. Battery solutions are among our strategic business areas and ensure energy security worldwide.”
Rolls-Royce’s battery solutions consist of modular units for capacity and power and can be flexibly configured to any size, says the company.

The components include integrated battery cabinets and the mtu EnergetIQ intelligent control system. They are used primarily for grid services, energy trading and the integration of renewable energies.
The interaction between home and large-scale battery storage is controlled by means of intelligent algorithms.
On the one hand, this should help to balance out the volatility of PV systems. On the other hand, the project aims to increase the local self-consumption rate to up to 100% at times. This relieves the power grid and increases the overall stability of the system.
Avacon and Rolls-Royce are also collaborating on a second research project. The aim is to use battery storage to moderate generation peaks from PV systems and bring them into line with electricity consumption.
