Student* with Master Thesis (optional) Tensor Decomposition for Power Systems

Who we are ...
Our primary focuses at Fraunhofer IWES are on wind energy and hydrogen technologies. Our institute is home to more than 300 scientists and employees as well as over 100 students from over 30 countries pursuing careers in applied research and development at nine sites. We secure investments in technological developments through validation, shorten innovation cycles, accelerate certification procedures, and increase planning accuracy by means of innovative measurement methods.

This team needs your support ...
You will be part of the »Application Center for Integration of Local Energy Systems« at our site in Hamburg. At present, our team consists of eight research associates and several students. We focus on the modelling and control of decentralized, local energy systems for network integration. One of our main research interests is cross-sector applications with hydrogen systems. On the control side, our current research emphasis is on grid-forming control for the integration of hybrid power plants including large-scale electrolyzes. Besides that, under the lead of the team of our partner University of Applied Sciences Hamburg we are developing a new modeling class, called multilinear models. Become an active member of the team; we are keen to hear your ideas! As an international oriented IWES-team, we highly appreciate an open exchange, whether this be in German or English. Respectful cooperation is also very important to us. You are wondering what you can bring to the team?

What you will do

These duties await you ...
You will dive into tensor decomposition of multilinear models of power systems. Power systems keep increasing in size and complexity, posing a major modelling challenge. When dealing with truly large-scale systems, we can use different approximation techniques, like Kron reductions from graph theory for networks. The aim is to find an approximation of the system of manageable scale while preserving its essential properties. One promising method for power system model approximation is the use of multilinear models which enable major reductions using tensor (multiarray) decomposition methods. Here you can develop model reduction routines for large-scale sparse power networks using tensor decomposition for multilinear models. You also analyse and compare the proposed multilinear tensor decomposition approaches against state-of-the-art techniques, e.g., Kron reduction, in terms of performance and accuracy.

What you bring to the table

What is your background?
Are you currently enrolled in a master's degree program studying Electrical Engineering, Control Engineering, Applied Mathematics, or a related subject? Do you have experience in MATLAB/Simulink or Python and are you fluent in English? Are you ready to delve into mathematical problems, especially the decomposition of tensors? Great! 

What you can expect

What we can offer you ...
We offer various opportunities to join us as a student. Whether it is an internship, where you gain a comprehensive insight into the areas of work, or the role of a student assistant, which is easy to combine with your studies. Are you looking for an exciting topic for your thesis and do you want to delve deeply into a topic scientifically? Together, we will find the right path for you! We know that studying can also be very demanding and requires a certain level of flexibility. That is no problem here, as – in agreement with your colleagues – you can decide flexibly what days and hours to work. Temporarily, you can even work remotely, depending on the job.
