Taking a closer look at electricity consumption with the help of artificial intelligence

- EN - DE
Non-intrusive load monitoring (NILM) can be used to analyze which devices in a household are currently consuming electricity without having to install separate measuring instruments on all consumers. Emir SinanoviÄ, a university assistant in the Smart Grids working group at the Institute of Networked and Embedded Systems, now wants to link this analysis with a large language model that works in a similar way to ChatGPT.

-A kettle shows a different power consumption curve to a fridge. Non-intrusive load monitoring can be used to calculate which appliance is currently in operation based on various parameters," explains Emir SinanoviÄ. He now wants to combine this analysis with a large-language model that provides information about existing consumption and predictions about future trends. This makes sense for several areas of application: -Many users do not want to interpret data themselves and would benefit from having better prepared information at their disposal. For example, older people who live alone could be supported by informing relatives about deviations in everyday electricity consumption that could indicate that something has happened to the person.

In order for a large language model to learn, it needs a lot of data. Real data is available, for example, in the form of pools from Austria and Italy. In addition, researchers in the Smart Grids working group have already been working on hardware and algorithms for mini-computers that are attached directly to the household’s electricity grid and used to query and deliver data quickly and at a high frequency. Emir SinanoviÄ, who took up his post in December, can now build on this.

For Emir SinanoviÄ, it goes without saying that data protection is particularly relevant in this sensitive area. -How to ensure that private data remains secure will also be the subject of my work," he reports. In addition to private households, the technology could also be highly relevant for companies, which would also have more information about their energy consumption available in this way and could thus increase their energy efficiency.

Emir SinanoviÄ has been interested in smart grids for a long time. Alongside his bachelor’s degree in information technology, he worked in software development for web applications at Lakeside Park. This was followed by a Master’s degree in Information and Communications Engineering, which he completed in 2023. His Master’s thesis supervisor Wilfried Elmenreich is now also the supervisor of his doctoral project. Emir SinanoviÄ was already introduced to technology as a pupil in the computer science subjects at the commercial academy in Klagenfurt: The enthusiastic computer gamer not only wanted to use IT, but also to develop it himself. -Just programming wasn’t enough for me either. That’s why I was glad to have found the bachelor’s degree course in information technology, which combines software and hardware," he explains. -The fact that I can now delve even deeper into the subject as part of a dissertation is a great pleasure. I’m learning a lot more along the way - and I can only benefit from that."

Do your parents understand what you are working on?

In principle, yes, but if I were to go into detail, anyone who isn’t a specialist would probably find it difficult to understand the technical terms or connections.

What’s the first thing you do in the office in the morning?

Switch on my laptop and then grab a cup of coffee and a glass of water.

Who do you think is the greatest scientist in history and why?

Every scientist contributes to expanding the knowledge of mankind with his/her work and that is something great.

What makes you angry?

Injustice.

And what calms you down?

Standing on top of a mountain and enjoying the peace and quiet and the view.

Do you really go on vacation? Without thinking about your work?

Yes, it’s very easy for me.

What are you afraid of?

Not being able to do all the things I have planned before the time comes to leave the earth.

What are you looking forward to?

With reference to the last question, exactly the things I still have planned. But there are too many to list here.
