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: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
