Smart grids that manage electricity demand at the local – microgrid – level may help to reduce the transmission of electricity over long distances to balance regional over- and undersupply. In the GreenCom project, international partners from industry and research develop and evaluate such a "Smart Energy Management System". It will be demonstrated at CeBIT, March 10 – 14, 2014 in Hannover. Visit us in Hall 9, Booth E40.
The surge in the production of electricity from renewable sources increasingly leads to periods of oversupply, in particular during the daytime: When the sun shines, photovoltaic systems – and there are currently over 1 million panels installed in Germany – generate more electric power than can be absorbed in the regional grids. To enable a load balancing between regions, the capacity of wide-area grids needs to be increased significantly.
At times, however, the demand just doesn't exist. On the other hand, in the early evening hours there may be a demand peak that is difficult to satisfy and may even overburden the grid. To reap the full potential of renewable, environment-friendly solar and wind power and to reduce investments in wide-area grids and transportation losses, we need to better balance supply and demand at the local or regional level. This holds in particular for the highly volatile solar power.
In the GreenCom project, co-funded by the European Commission, a consortium from industry and research develops and evaluates a "Smart Energy Management System" for the local level. Private households and businesses are equipped with smart meters and additional networked sensors, e.g. for measuring temperatures. In near real-time, the system collects, aggregates and analyzes the energy consumption data as well as the renewable electricity generated in the neighborhood. On this basis the management system makes short-term (up to four hours) forecasts of local electricity supply and demand.
"The system is also connected to the major electricity-consuming devices in the households. Thus it can control the operation of heat pumps, refrigerators, washing machines or chargers for electric vehicles", explains Ms. Daniela Fisseler, GreenCom project manager at the Fraunhofer Institute for Applied Information Technology FIT.
Currently the partners in the GreenCom project are building a testbed to evaluate a range of application scenarios and to collect data for the analysis of a number of business models. Initial pilot implementations are available and are being extended. In parallel, the project works with the local electricity company to install the system in the households on the Danish isle Fur. There they will test and evaluate the different concepts for local grid management under real-life conditions, involving about 40 normal consumers and consumers that also produce electricity.
The GreenCom project is partially funded by the European Commission under the 7th Framework Programme (FP7 ICT-2011.6.1 Smart Energy Grids). The project consortium includes Instituto Superiore Mario Boella (coordinator), Sensing & Control Systems (SCS), In-JeT ApS, Tyndall National Institute – University College Cork, Actua A/S, EnergiMidt A/S and Fraunhofer FIT.

Longer, more severe, and hotter droughts and a myriad of other threats, including diseases and more extensive and severe wildfires, are threatening to transform some of the world's temperate forests, a new study published in Science has found. Without informed management, some forests could convert to shrublands or grasslands within the coming decades.
"While we have been trying to manage for resilience of 20th century conditions, we realize now that we must prepare for transformations and attempt to ease...
A University of Oklahoma astrophysicist and his Chinese collaborator have found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope.
The discovery of two supermassive black holes--one larger one and a second, smaller one--are evidence of a binary black hole and suggests that supermassive...
A team of European researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece. The study is published today (27 August) in Ocean Science, an open access journal of the European Geosciences Union (EGU).
Though not as frequent as in the Pacific and Indian oceans, tsunamis also occur in the Mediterranean, mainly due to earthquakes generated when the African...
In mountainous regions earthquakes often cause strong landslides, which can be exacerbated by heavy rain. However, after an initial increase, the frequency of these mass wasting events, often enormous and dangerous, declines, in fact independently of meteorological events and aftershocks.
These new findings are presented by a German-Franco-Japanese team of geoscientists in the current issue of the journal Geology, under the lead of the GFZ...
Bacteria do not cease to amaze us with their survival strategies. A research team from the University of Basel's Biozentrum has now discovered how bacteria enter a sleep mode using a so-called FIC toxin. In the current issue of “Cell Reports”, the scientists describe the mechanism of action and also explain why their discovery provides new insights into the evolution of pathogens.
For many poisons there are antidotes which neutralize their toxic effect. Toxin-antitoxin systems in bacteria work in a similar manner: As long as a cell...
