Energiewende meets Industrie 4.0

DC-INDUSTRIE overview

The German Federal government supports companies and research institutions in developing innovative technologies that support reaching the international climate targets. Specifically, the Energy Research Programmes of the Federal Ministry for Economic Affairs and Energy, focus on the large industrial and manufacturing base in Germany. Since October 2019, 39 partners - 33 of which are companies and 6 research institutes - have been working on seamless, efficient integration of renewable energy (e.g. solar panels on factory roofs) and storage devices for balancing power supply and demand in factories. The focus of DC-INDUSTRIE2 is the direct current supply of an entire production hall, after the direct current supply of a production cell had already been realized in DC-INDUSTRIE since 2016. The DC infrastructure will be realized and rigorously tested in nine model plants and transfer centres at various partners. They range in power levels up to approximately 2 MW.
The predecessor project DC-INDUSTRIE (2016 – 2019, with 27 partners) laid the groundwork for the power supply of industrial plants via a smart, open DC grid. The partners collaborated to implement the energy transition in industrial production achieving up to 80% reduction of feed-in power and a total recovery of braking energy in four model applications at the industrial partners.


In short, DC-INDUSTRIE provides: 
1.    An open system
2.    Efficient integration of renewable energy
3.    Lower energy consumption
4.    Reduced feed-in power
5.    Increased system availability

DC-INDUSTRIE at Hannover Fair 2021

Direct current plays a key role in the future industrial power supply. With direct current, more energy efficiency and energy flexibility can be realised in industrial production. In the DC-INDUSTRIE2 direct current project and its predecessor project DC-INDUSTRIE, more than 40 partners from industry and research have been working since 2016 to implement the energy transition in industrial production. This is how the industrial energy system of the future, a DC-based smart grid for industry, is being created. (German only)

SPS Connect 2020 | On the way to the DC factory

In the lecture, the manufacturer-independent industrial direct current network (DC network) of DC-Industry will be presented as a solution for the upcoming challenges of industrial energy supply. With DC-Industry, a consortium of well-known electrical engineering manufacturers and users from the automotive and mechanical engineering sectors wants to prepare the way for the DC factory, in which all energy is exchanged via a DC grid. In this way, industrial production can be made more energy-efficient and flexible across all sectors through direct current. (German only)

Direct current plays a key role in the future industrial power supply. Direct current (DC) can be used to achieve greater energy efficiency and energy flexibility in industrial production. In the DC-INDUSTRIE2 direct current research project and the predecessor project DC-Industry, research has been conducted since 2016 with companies from industry and research institutes on the direct current supply of a production cell or production hall (German only).

Video: Energiewende meets Industrie 4.0

ZVEI is developing grid management options for the future with its partners in the DC-INDUSTRIE project. The motto: Energiewende meets Industrie 4.0. Direct current plays a key role in the future industrial power supply. So will renewable energies, energy storage and a two-way power supply that converts alternating current into direct current and vice versa. The goal is a flexible, efficient and open smart grid. The animation of the DC-INDUSTRIE project shows what the energy supply of tomorrow will look like, what grid management will have to do and what actually happens to the surplus electricity at the weekend.

Quick check: Bidirectional power supply

A central AC/DC converter supplies all load areas of the factory with direct current. In this way, the overall energy efficiency of the system increases and the rectifiers in the units can be saved. The energy supply in the factory's DC network is not a one-way street: energy feedback into the AC network is also possible.

Quick check: Renewable energies

The DC grid enables easy integration of photovoltaic cells and other renewable energy sources. Conversion losses are reduced; synchronisation with a three-phase AC grid is not necessary.

Quick check: energy storage

Energy storage is easier to integrate into the factory DC grid with lower conversion losses. This ensures production stability in case of AC grid failure and better balancing of peak loads.

Quick check: grid management

The decentralised grid management is new. It ensures optimal energy exchange between the plants and brings more stability to the industrial power grid.

Quick check: Robot production | Industrial robots

The dynamic energy demand of robot production benefits from the distributed energy storage in the DC grid. In addition, the high proportion of recuperative energy provided by the industrial robots can be fed back into the system and used.
