Making Wind Power More Efficient

10.06.2003


A University of Ulster researcher has come up with a new method, using Artificial Intelligence techniques, to forecast wind energy more accurately than ever before.


Predicting how fast the wind will blow has always been a major problem for wind farm operators. It is essential that they have some idea of how much electricity they will be able to produce each day based on the strength of the wind.

Energy forecasting has become a critical factor in the efficient generation of power from wind turbines.

Piers Campbell and Dr Kenny Adamson, from the School of Computing and Mathematics, have employed Artificial Intelligence techniques to assess and learn from past wind flow patterns, subsequently predicting energy output up to twelve hours in advance, more precisely than ever before.



Mr Campbell, a researcher at the University, said: “There are forecasting models in existence in the UK and Ireland but they are highly inaccurate due to the fact that they were developed for a Danish market and their application in this country is simply not effective at the moment without further research.

“At present, the techniques that we have developed can forecast how much wind energy will be produced within a 12 percent margin and we hope to reduce that even further, current utility expectations work within a 50% margin of error.

“The need for forecasting is essential in increasing the competitiveness of wind energy as a renewable power source and in assisting integration with conventional power sources. The supply and demand of electricity is balanced in half-hourly trading periods and generators are required to forecast the amount of energy they will supply 3.5 hours ahead of delivery. The system then punishes generators for any imbalance, positive or negative. With such penalties in place, it is obvious how these new techniques are vital in improving the efficiency and cost effectiveness of wind farm operations.”

There are currently seven wind farm sites generating electricity in Northern Ireland, with a further eight in progress. At present, 1.8 percent of Northern Ireland’s electricity comes from renewables such as wind energy but the targets proposed by government aim to increase this to at least 15 percent by 2010.

Mr Campbell believes this is an attainable figure and one that Northern Ireland should be striving to excel: “The main advantage of wind power is that it is much cleaner and less polluting than fossil fuels. Wind energy plants produce no air pollutants or harmful green house gases that contribute to climate change.

“Using AI techniques we can also reduce the time it takes to assess an area for suitability as a wind farm site. Using current methods this can take up to one year but now we can evaluate a site much more quickly, enabling faster development of wind farms throughout the country.

“The technology will also enable developers to predict wind speeds and power output for the next 2 or 3 years rather than simply basing their assessments on the wind speeds measured over a single year.”

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
