One of the new virtual power plants enables the Munich municipal utility company to run six of its cogeneration modules, five hydroelectric facilities, and one wind-power plant more efficiently and economically than if they were operated separately. The facilities have a combined output of 20 megawatts.
In addition, they can help improve grid stability by making controlling power available in the minute reserve range. Virtual power plants are ideally suited for renewable sources of energy. Since Germany's Renewable Energy Act was amended in January 2012, the associated market subsidy system encourages operators to sell electricity from their virtual power plants directly on the energy markets. As a result of the "energy revolution," the importance of virtual power plants in smart grids is expected to grow.
The distributed energy management system from the energy automation experts at Siemens uses sophisticated information and communications technology to network and combine the various decentralized power producers so that they can be centrally managed. To make this possible, the system processes all of the relevant information, including weather forecasts, current electricity prices, and energy demand. On the basis of this data, the system draws up an operation schedule for all of the associated facilities and monitors its implementation.
The system updates its energy consumption prediction every hour, depending on the weather forecast and the type of day. The operation schedule minimizes the costs of generating electricity and operating the facilities within the virtual power plant network. In doing so, the system takes economic as well as environmental aspects into account.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
