Storage Heaters as Buffers for Wind Power

15.11.2013
As reported in the latest issue of "Pictures of the Future", Siemens and RWE are planning to use storage heaters to make surplus solar and wind power more usable.

In the RWE Wind Heating project, the two companies have worked together with tekmar Regelsysteme GmbH to equip the storage heating systems in two neighborhoods with smart control devices.



The storage heaters were programmed to charge their heat stores whenever there was too much sunshine or the wind was blowing. The test phase begun in 2011 has shown that the concept is very effective.

State-of-the-art storage heating systems that are appropriately set up for the buildings they heat are energy-efficient, inexpensive, and simple. The units charge the heaters at night using inexpensive power, and release the heat again during the day. However, instead of storing off-peak power at night, the heaters could also act as a temporary store for surplus wind and solar power.

According to energy experts, all of the storage heaters in Germany could potentially store 14,000 gigawatt-hours (GWh) of power each year. By contrast, Germany's pumped-storage electrical power stations have a combined storage capacity of around 40 GWh per year.

An important precondition for the use of storage heaters as buffers for green electricity is the availability of a smart control device for the charging process. This is made possible by the Siemens software DEMS (Decentralized Energy Management System), which generates consumption forecasts based on existing user data. The software then uses these forecasts as well as information about the weather, the current electricity prices, and the amount of storage capacity available to decide when a heat store should be charged. The command is transmitted to the control unit via wireless.

The concept has been tested in residential areas containing a variety of storage heating systems: underfloor heating, separate furnaces, and block storage units. What the residents particularly like about the systems is that they heat the apartments evenly.

Whereas a wind-powered heating system is continuously recharged during the day, conventional storage heaters are very warm in the mornings and cool off toward evening. The task now is to make the system attractive for all users of storage heaters by finding ways in which they can benefit from inexpensive wind and solar power prices.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
