Power snapshots from smart meters by Siemens provide synchronous grid information with maximum precision from the low-voltage grid, data that can serve as a basis for analyzing these grids in cities and communities.
That’s why developers from Siemens Austria developed the PSSA, with which the smart meters in local grids were equipped. These meters don’t only record energy-use data; they also generate real-time and synchronous displays of voltages in the local grids at points in time that are critical for the grid technology. The accuracy of the data is unprecedented because the load variations of the phases and the ground return conductor are also recorded. This information on the actual conditions in the grid enables grid operators to more efficiently use the available infrastructure. To compensate for power consumption peaks, the operators can for example take load groups like electric heating systems or heat pumps offline without compromising end users’ convenience. The data also can be used to estimate investment costs for expansions of grid infrastructure.
PSSA will be launched on the market before the end of 2012. Siemens smart meters, which are already being used by many customers, can be equipped with this additional function by means of a firmware download without disturbing the validity of the meters’ calibration.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
