From now on, it will not take three hours, but ten minutes, before we receive news about the location of clouds over Denmark. And this will help to make even better use of energy from the sun. This is the announcement from the Danish Meteorological Institute (DMI), which has entered into a new collaboration on weather forecasts with Energinet.
A new satellite thousands of kilometers above the ground and artificial intelligence will help deliver faster weather forecasts. And this can help Energinet optimize when to turn on and off power plants in order to balance the electricity grid.
Previously, it took three hours before a forecast about cloud activity was ready, but in future it will take ten minutes, says Irene Livia Kruse from DMI. She is one of the researchers behind the project.
- With the new satellite, we can better see where the clouds are over Denmark. And then we can use artificial intelligence to predict where the clouds are moving, she says.
Can ensure savings
As renewable energy constitutes an increasingly large share of Denmark's total energy production, larger and larger amounts of money are being spent on balancing the electricity grid, writes DMI about the project. Balancing the electricity grid is Energinet's main task. And overall, it can save the Danes some costs that it now has more precise forecasts to work from, Energinet informs Ritzau.
Researcher Irene Livia Kruse elaborates:
- The model we normally use to predict the weather takes several hours to come up with the predictions, because it first has to carry out millions of calculations. It takes three hours to deliver.
In addition, it is not very good at predicting clouds in the right places, and it also lags behind in terms of seeing clouds that can both form and dissolve suddenly, adds Irene Livia Kruse.
- What is new in this model is that it is specifically based on only predicting images from satellites. That is why it is much faster, she says.
The new satellite is in place and in use, but it will be a little while before the predictions based on artificial intelligence are completely ready.
- It will probably be ready at the beginning of next year. It is about getting the entire model up and running operationally, says Irene Livia Kruse.
Energinet is an independent public company under the Ministry of Climate, Energy and Utilities. It owns and operates the Danish energy infrastructure.
