Ensuring the continuous stability of the electricity grid is posing increasing technical challenges for the grid operators. One possibility is to use large-scale battery storage systems to compensate for temporary fluctuations between the supply and demand. The new BINE-Projektinfo brochure entitled “Modular battery storage system supplies balancing energy” (12/2017) presents the large-capacity M5Bat storage system in Aachen.
The interaction of five different battery systems based on lithium-ion or lead-acid is being investigated there on a large scale. The system participates in regular trading in the electricity market for system services. After one year of operation the initial results are now available.
Testing technology and business models
The large-scale storage system has six strings in which various lithium-ion batteries are installed, and four strings with lead-acid batteries. The scientists are using this modular design to test the interaction of the different battery systems.
Each of the strings can be individually controlled and regulated. Lithium-ion batteries are more suitable for short-term power storage and output, while those with lead-acid are more suitable for short and medium charging and discharging times.
The research project is focussing on the ageing, technical reliability and service life of the systems as well as on optimised battery management. The large-scale storage system runs fully automatically and is controlled by an external control centre.
It is certified for participation in the balancing energy market. In the event of a sudden power demand in the grid the storage system can immediately supply the required electricity for seconds or minutes in order to keep the grid frequency stable.
The storage system has an output of 5.8 MW with a storage capacity of 5.6 MWh. The output and capacity of the system are roughly equivalent to the electricity consumed by 10,000 households in an hour. The Institute for Power Electronics and Electrical Drives (ISEA) at RWTH Aachen University is conducting the research together with industrial partners.

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
