Wind power stabilises the electricity grid

01.10.2014

Balancing energy from renewable energies

A balanced ratio between the production and consumption is constantly required in electricity grids. To compensate for the unavoidable fluctuations and to ensure the grid frequency of 50 Hertz, network operators require a reliable power reserve, known as control reserve.

The BINE Projektinfo brochure “Stabilising the grid with wind power” (08/2014) presents a new concept as to how wind farms can also participate in future in bidding for control reserve. This will enable a pool of wind farms to provide part of the balancing power required in the German electricity grid.

Wind energy is primarily concerned with minute reserve power. With frequency fluctuations this must be fed into the grid within quarterly hour intervals. Until now the capacity has been tendered on working days for the next day. Scientists have developed new calculation methods to enable pools of wind farms to submit bids. As a second component in the concept, they have tested two methods for verifying the balancing energy actually supplied.

With the introduction of direct marketing, the reform of the 2012 Renewable Energy Sources Act created the general legal prerequisites for wind power’s participation in the bidding process.

However, before the newly developed concept can be used in practice, changes to the existing regulations for the balancing power market are still required. The concept has been developed by staff of the Fraunhofer Institute for Wind Energy and Energy System Technology IWES in collaboration with industrial partners.

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,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
