📽️ Interview with Gregor Giebel, Operating Agent of IEA Wind Task 51: “We need the #forecasts because of the wider implications for the energy system. If there’s more than enough wind power in the grid, then prices are going to get down. And if you know that in advance, then we can adjust our behaviour accordingly. I can charge my electric car when the price is low. I can shift my own consumption – for my dishwasher, for example – into the night because consumption is low.”

One of the most exciting developments in the field is #AI. Gregor explains:

“This is a field that didn’t exist five years ago. And what we are seeing is that these forecasts can be run on a much smaller computer in much quicker time. I’ve even heard voices saying, in five years’ time numerical weather prediction as we know it on supercomputers in national weather centres is only used for training the AI models. And with those AI models we can see much quicker turnaround in terms of how much there is coming, but also, we see already better performance than from the classical numerical other prediction models.”

The interview took place last week at DTU Campus #Risø in Denmark during the Task 51 annual meeting. It gathered more than 40 participants. The event was held as a joint workshop with IEA Wind Task 50 – Hybrid Power Plants.

IEA Wind Task 51 is the world’s largest collaborative group on renewables forecasting. The diversity of experts among the participants is really unique, ranging from academics, meteorologists, industry specialists, and end users from around the world. Task Managers are Corinna Möhrlen and Caroline Draxl.

“The unique thing about the collaboration in the IEA Wind task is that, first of all, it’s a global group,” says Gregor. We’re having 12 countries, soon more, and we are having from all different sectors, so from the meteorology all the way to the end users, everyone together in a room, and they share quite openly in the discussions: What the bottlenecks for further implementation, how can we make forecasts better, how can we use the forecasts better, how can we get the most value out of the forecasts?”

A Task 51 workshop on AI will be held during spring next year.
