Wind energy not limited by technical barriers

22.12.2003


Dutch research has demonstrated that there are no technical barriers to wind energy generating a significant part of the electricity supply. With the appropriate technical measures, possible problems in the electricity grid can be taken care of properly.



Researcher Han Slootweg developed simulation models, which demonstrate how wind energy affects the behaviour of electricity grids in concrete situations. These simulation models can also be used to establish the precise nature and size of any technical measures that might be required.

An initial analysis with the model revealed that there are no technical barriers to wind energy generating a significant part of the electricity supply. Technical measures are available to resolve any unexpected problems that arise. Research has shown that the measures chosen are strongly dependent on the type of wind turbine used and this must therefore be taken into account.


Slootweg first of all developed simulation models for different types of wind turbines. Then he developed models for complete wind parks, in which an entire wind park can be simulated at once. The input for the model consists of data from the type of wind turbine used in the park, the location of the individual turbines within the park and the wind speed.

These simulation models were used by Slootweg to investigate the effect of wind turbines on the behaviour of an electricity grid. To this end, he continually substituted some conventional generators with wind turbines, and then compared how different electricity networks responded to a number of events. For example, he investigated how the electricity grid responded to short circuits and changes in the amount of electricity generated due to generator failure.

The research has provided important insights into the consequences of connecting wind turbines to the electricity grid for the grid’s stability. The behaviour of the electricity grid is to a large extent, determined by the power stations connected to it. Wind turbines differ from conventional power stations, which run on coal, natural gas or nuclear fission, in two fundamental aspects. Wind is the primary energy source of wind turbines and the wind cannot be controlled. Wind turbines also contain different types of generators. As a result of this, wind turbines have a very different effect on the electricity grid from that of conventional power stations.

Han Slootweg’s doctoral research was carried out within the framework of the Energy Research incentive programme. This programme is a joint venture between the Netherlands Agency for Energy and the Environment (Dutch acronym: Novem) and the Social Sciences Research Council of NWO.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
