The result is the industrial energy system of the future, a DC-based smart grid for industry.
As part of the HANNOVER MESSE Digital Edition, a panel discussion entitled "DC-INDUSTRIE paves the way for the industrial DC grid" will be held.

KEBA Industrial Automation Germany GmbH is part of the DC-INDUSTRIE2 research project, which is one of the largest collaborative research projects in Germany with 35 industrial partners, five research institutes and the ZVEI. By the end of 2022, the DC grid concept will be expanded into an intelligent DC supply system suitable for supplying a production hall or large-scale process engineering plants with energy at low cost. The project is funded by the German Federal Ministry for Economic Affairs and Energy (BMWi).
DC technology has many advantages, which are used to meet the requirements of a modern, intelligent industrial power supply network. For example, new energy generation systems such as photovoltaics or energy storage systems can be integrated very easily, since they generate a DC voltage anyway. Furthermore, plant availability increases because a DC grid can react flexibly to disturbances in the AC grid. A DC grid can even actively support the AC grid; this grid serviceability is particularly important in weak grids or with a high proportion of decentralized energy producers such as photovoltaics.
KEBA Industrial Automation Germany GmbH is researching several aspects as part of DC-INDUSTRIE2: Supply units are being built and validated that feed power from the DC grid from the AC grid, with the option of parallel operation and optimized EMC behavior. Servo controllers and drive systems are integrated into the DC grid and supplied with DC. In addition, an active energy storage system will be set up to absorb braking energy, reduce the peak power absorbed from the AC grid and bridge short grid outages. Together with all project partners, the system concept will be further developed to ensure simple and reliable operation of all participants in the DC grid. The components and processes are being tested in nine transfer centers and model plants.
