Berlin, 05.05.2021 The project partners Ernst Knoll Feinmechanik GmbH, Fraunhofer ISE, Solandeo GmbH, the BVES Bundesverband Energiespeicher Systeme e.V. (Federal Association of Energy Storage Systems) and EDF Distributed Solutions GmbH are working on solutions to improve the integration of energy storage systems in industry in the BMWi-funded "DABESI" project. To this purpose, the dimensioning and operation of different storage technologies are to be investigated for relevant applications and the optimised use of these storage systems in medium-sized industrial companies, taking into account company-specific load profiles.

Storage solutions actively contribute to the energy transition

Energy storage systems offer a variety of options for improving the integration of renewable power generation into the energy system and energy efficiency, thus enabling a stable and at the same time green power supply. However, only a few storage systems have been installed so far, especially in medium-sized industrial enterprises, the central pillar of the German economy. Yet a cost-effective power supply and efficient use of resources are essential for these companies in order to sustainably survive in international competition. One challenge in identifying and realising optimisation potential in this segment, however, is complex and very individual production processes, a wide variety of entrepreneurial framework conditions and numerous regulatory requirements, which often require extensive analysis.

Practical investigation of measurement data and storage models

In five successive project phases, methods of measurement data analysis, models for storage dimensioning, self-learning control algorithms (keyword AI) for storage operation and scalable storage system architectures are investigated or developed and then installed and tested in selected industrial plants.

Based on a combined operation of the electrical storage system for peak load capping and the provision of primary control power, the project developments are intended to optimise the sizing and operational management of the storage system and integrate further use cases - such as uninterruptible power supply, self-consumption increase, price-dynamic load shifting or stabilisation of the local grid.

In parallel, the prototype of a flexibly deployable, modular hybrid energy storage system is being developed, which will combine the respective advantages of lithium and redox flow storage technology. Finally, both the prototype and the control algorithms will be extensively tested in the Digital Grid Lab at Fraunhofer ISE and in a field test.
