Open software platform helps to save energy

13.08.2010
Starting 2011, energy suppliers will be obligated to offer variable power prices. A new energy management software platform will enable customers in future to opt for fl exible electricity rates, so that they can purchase power at times when it is available more cheaply.A further advantage is better utilization of the power grid.

Faced with rising electricity and heating costs, more and more consumers are opting to save energy, and now the government is beginning to help them. As from 2011, energy suppliers will be required to offer electricity at variable rates under the German Energy Act (EnWG § 40,3).

The idea behind the new law is simple: variable rates should encourage people to make a conscious effort to control their consumption. This is where the new open software platform will come into its own in future, helping electricity consumers to handle the new fl exible rates and make their energy consumption more intelligent. The OGEMA (Open Gateway Energy Management Alliance) Framework was developed by the Fraunhofer Institute for Wind Energy and Energy System Technologies IWES in Kassel. It is a freely available Java-based, opensource platform for energy management that links both consumers and producers of energy to the control centers of the grid operators and power suppliers. Via a display, customers will be able to monitor a variable electricity price and wait for times when rates are lower in order to start their dishwashers for instance. »Variable rates allow demand for electricity to be steered. When grid utilization levels are low, electricity can be offered at lower rates. This makes it lucrative, for example, for consumers to run their washing machines at night. Flexible pricing is an incentive to gradually shift power consumption to times when there is an oversupply of wind energy. After all, with the growing trend towards to renewable energy sources it is becoming ever more important to adapt one‘s consumption to suit the supply.« That is how Dr. Philipp Strauß, engineer and division director at IWES, explains the concept behind the software.

But nobody really wants to spend time checking up on electricity prices several times a day, which is why the researchers responsible for the OGEMA Framework developed a software program called BEMI (Bidirectional Energy Management Interface) that relieves consumers of this very task. The software automatically controls appliances such as refrigerators, washing machines, heat pumps and air-conditioning. But OGEMA programming is not just the domain of the researchers: True to the principle of other open-source projects such as Linux, all developers are free to design software for the platform, thus implementing their ideas for the automated and more effi cient use of energy. »Currently, there is no open system for the home automation fi eld that enables different manufacturers to develop dedicated apps,« says Dr. David Nestle, IWES group manager, underlining the special feature of the OGEMA Framework.

In order to continue developing the concept and making it better known, the IWES launched the OGEMA Alliance this summer, which a number of companies, such as Mannheim-based energy supplier MVV and solar energy wholesaler Entrason, have already joined. »Our hope is that, within a short space of time, numerous applications will arise to meet the needs of private households and small businesses,« says Nestle. One conceivable innovation is an app that adapts the operation of electrical appliances to the power generation pattern of a household‘s own photovoltaic system or that coordinates individual room heating to suit the consumer‘s daily routine.

At the moment, researchers are working on the fi rst version of the OGEMA-software, which will be available later this year as a gratis download: An fi eld test will be carried out as part of the E-energy projects »Modellstadt Mannheim« and the EU-sponsored SmartHouse/SmartGrid. Initially, the use of the system will be tested in 100 households, with a further fi eld test involving 1500 customers planned for next year.

Im Focus: Significantly more productivity in USP lasers

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:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

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...

Im Focus: Quantum Particles Form Droplets

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...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

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,...
