Master Thesis - Physics-Informed Machine Learning for Dynamic Power System Characterization

At the Institute of Climate and Energy Systems Engineering (ICE-1) we focus on the development of models and algorithms for simulation and optimization of decentralized, integrated energy systems. Such systems are characterized by high shares of renewable energies and increasing sector coupling, which leads to high spatial and temporal variability of energy supply and demand as well as a high degree of interdependence of material and energy flows. Our research at the ICE institute aims to provide scalable and faster-than-real-time capable methods and tools that enable the energy-optimal, cost-efficient and safe design and operation of future energy systems.

Your Job

The transition toward renewable and converter-interfaced energy resources is creating increasingly fast and complex dynamics in modern power systems. In this Master’s thesis, you will develop a physics-informed digital-twinning approach to better characterize these dynamics and estimate relevant electrical and control parameters from transient voltage and current data.

Your tasks will include:

• Developing and analyzing representative dynamic simulation scenarios for electrical power systems
• Extending kernel-based Gaussian Process methods for the estimation of electrical and control parameters
• Integrating physical knowledge, such as governing differential equations and physical constraints, into probabilistic kernel models
• Developing and evaluating a physics-informed digital-twinning methodology based on known system parameters and reference simulations
• Assessing the approach with regard to estimation accuracy, uncertainty quantification, numerical robustness, and computational efficiency
• Analyzing and documenting your results and deriving conclusions for the applicability of the developed approach

Your Profile

• Excellent university degree (Bachelor) in field of Data Science or a comparable field i.e. Electrical Engineering, Computer Science/ Engineering, Physics or the like
• Strong mathematical background
• Interest in energy systems, power grids and their components
• Excellent knowledge and experience in programming Python
• Excellent knowledge and experience in machine learning
• Excellent ability for cooperative collaboration
• Very good command of written and spoken English with extensive vocabulary is required (at least B2 level according to the CEFR

), ideally supported by a certificate confirming the language level. Knowledge of the German language is not mandatory but certainly appreciated
