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: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
