The global wind and energy sector is currently gathered in Copenhagen for the WindEurope Electric City 2021 event, and as an important player in this field of research, DTU is also taking part.
Green electrification of society requires energy from renewable energy sources. So far, wind is the safest bet on an energy source that can supply the necessary green power. If we are to achieve the European target of a 55 per cent reduction of greenhouse gases and the Danish target of a 70 per cent reduction of greenhouse gases by 2030, the wind power industry has a busy time ahead.
HRH Crown Prince Frederik, who opened the event on 22 November, shares the industry's interest in accelerating the green transition.
"The challenges are big, but so is the potential," as he pointed out.
One new area of development is the digitalization of the huge energy plants that the wind turbines of the future will be based on. Studies by WindEurope show that digitalization is key to making just about everything faster, smarter, and cheaper. And digitalization is a field that DTU is particularly interested in.
Research boosts efficiency
Among other things, DTU conducts research into so-called digital twins, which generate a digital model of a wind turbine via sensors on the physical wind turbine. By collecting data from the physical wind turbine throughout its service life, the researchers gather new insights. Using the digital twin and automated monitoring, the researchers can track and predict the future state of each wing throughout its life cycle. This generates information about each wing's movements, rotations, wear, and fractures, which can be used to optimize the production and maintenance of wind energy systems.
The digital twins of wind turbine blades are being developed in collaboration with, among others, IBM, Siemens SIMCENTER, and a number of SMEs, which are linked to the Danish wind industry.
