farms are amongst the biggest makers we construct– vast varieties of towers topped with gradually turning blades. They create megawatts of power from their huge turbines, using up miles of space.
That implies that, as green as they are, they still have an immense effect on the ecology around them, affecting birds, fish, and even the development of kelp and other marine plants.
Managing those turbines is a huge problem. We can’t look at them in isolation as much as we ‘d like to. Instead, we need to consider them as part of a larger system, one that consists of the environment they become part of.
Rather of optimizing those turbines for power generation, we have to be able to manage them to allow moving birds to pass, at the same time making sure marine plants do not impact their moorings which fishing boats don’t harm pylons as they follow shoals of herring and other fish into the farm.
It starts with puffins
The initial incentive for the task wasn’t a digital twin as such, instead it was using AI models to count the puffins on a remote island off the Scottish coast. As SSE Renewables was building a wind farm some 200 miles from a significant puffin reproducing ground on the Island of May, the company wished to know if the turbines were influencing the puffin population.
It’s hard to count puffins; they spend eight months of the year out at sea, going back to coast to reproduce, just laying one egg a year.
A set of electronic cameras near the reproducing burrows capture a live stream of puffin motions, which are fed to an experienced design that can track specific birds, even keeping in mind when they leave and return.
The island is one of the U.K.’s largest puffin reproducing grounds with over 80,000 birds, making it a perfect place to track fluctuations in population and to try to understand if the close-by wind farm is triggering any modifications.
Utilizing AI to count puffins isn’t a digital twin, but it’s one input and one technique we can use to construct a massive model of the environment around a wind farm. No 2 wind farms are the exact same: They utilize different turbine types and are built in different coastal waters and wind patterns.
As an outcome, they’re in different bird migratory patterns and host different types of fish. Any ecological design used as part of a control system requires to be custom for each wind farm.
Handling wind farms in the cloud
Part of the approach that Microsoft and its partner Avanade are taking is to use a wide variety of different sensor types to get an understanding of what is happening around the wind farm, and using that information to build a complex, near-real time view of conditions. The goal is to eliminate slow, manual counting techniques, similar to the puffin counting service presently in usage.
Modern ecological sensing units can be passive, like cameras or microphones, or active, like lidar and radar. That makes them less invasive than utilizing webs to sample fish or sending out in scuba divers to make a count.
A variety of AI-interpreted sensors gets around the constraints that include human intervention, gathering data in all conditions and at all times of day.

Models like this can benefit from cloud scale to run several simulations in parallel at a sped up rate. If a storm is approaching, what will be the result of slowing the turbines, and to what speed?
The outcomes of simulations like these can be compared to actual data, adding an additional feedback loop that lets the team improve their designs, so the next set of results will be more accurate. The information can then be used to train machine learning models to recognize conditions that are likely to cause issues, so appropriate protections can be used.
Working with large, complex systems
This approach will enable SSE to experiment with reducing dangers to migrating birds. For example, they can figure out a maximum blade speed that will enable flocks to pass safely while still generating power. By comprehending the environment around the turbines, it will be possible to manage them better and with substantially less environmental effect.
Simon Turner, primary technology officer for data and AI at Avanade, explained this method as “a free company.” Here, information and AI collaborate to provide a system that is successfully self-operating, one he described as utilizing AI to “care for certain things that you understood that could assist the system to make decisions on your behalf.”
Secret to this method is extending the concept of a digital twin with machine learning and large-scale data. Historical data can be used in addition to real-time data to build models of large, intricate systems, which can broaden out to whole environments.
As Turner notes, this technique can be reached more than wind farms, utilizing it to design any complicated system where adding brand-new components might have a substantial result, such as understanding how water catchment areas work or how hydroelectric systems can be tuned to let salmon pass unharmed on their way to conventional breeding grounds, while still producing power.
There’s another element to the wind farm project that reflects the ethos behind Microsoft’s AI for Earth program: All of the data gathered will be shared outside SSE Renewables and will be readily available to marine and other environmental scientists.
The resulting dataset must be an important resource for preparing brand-new wind farms and for any other continental shelf facilities projects. This includes another feedback path, permitting researchers to add their competence and analysis to the data.
Utilizing existing Azure services
Azure is a perfect platform for this kind of application. Most of the tools needed to build it are already in place: Azure IoT Hub to handle sensing units; Data Lake to process the enormous data storage requirements; and Azure’s AI tooling to develop, test and utilize the resulting models together with its existing Digital Twin product to host and run models.
It’s an approach that’s scalable and versatile adequate to support the differences in between wind farms constructed and operating in different places. As brand-new data points are discovered they can be added to the models, permitting the platform to adjust to new information and to brand-new concerns from the team running the wind farm and managing its ecological effect.
Data will require to be saved for extended periods, as the impact of a wind farm is one that’s years long, so designs require to work over the order of seasons and years, even decades, not just minutes and seconds.
Large scale digital twins like this are the sensible next action in the industrial Web of Things. Microsoft is currently seeing interest from other consumers with complex systems that need tracking and control.
That becomes an advantage for Microsoft itself, as it has a commitment to end up being carbon unfavorable, so it needs to deal with ingenious renewable energy companies to develop new methods to lower its environmental footprint.
There’s another aspect to making use of massive ecological models like this, because their outputs could be shown other systems, for instance providing data for Microsoft’s own precision agriculture platform FarmBeats.
