PhD Machine Learning for Energy System State Estimation

Challenge: Transforming the conventional carbon-intensive energy use
Change: AI to turn data into knowledge for efficient systems
Impact: Boosting the sustainable, fair and reliable energy transition

Job description
TU Delft is a top-tier university and is exceedingly active in the field of Artificial Intelligence (AI) with a strong expertise in energy systems. Energy systems are the backbone of our modern society but are becoming increasingly complex and challenging to operate as renewable energy, heating and transport sectors are integrated into the system. It’s crucially important that energy systems are sustainable, reliable and effective, now and in the future.

As part of your 4-year PhD project, you will develop novel graph-based machine learning algorithms for state estimation of energy systems. The scientific challenge is to design a real-time state estimator for an active distribution system considering topological uncertainties. State estimation is an important task where the operator considers very little noisy measurement data to infer the full system state. However, often, the accuracy is used to infer the full state while the true state is seldom known and can only be reproduced in computer simulations. Therefore, you will explore a novel approach investigating graph neural networks and structural information combining with parameter estimation methods. Your PhD research will be in the area of applied data-driven scientific computing combining statistics, time-frequency analysis, low-dimensional model reductions, and other techniques to extract information from data. You will apply self-supervised learning making the information useful for the management and planning of complex energy systems considering foundational models.

You will be hired as a PhD researcher at TU Delft. You will be jointly supervised by Associate Professor Dr. Jochen Cremer (academic supervisor) and Dr. Nuran Cihangir (your company supervisor, Stedin). Recognising the transformational power of AI, TU Delft joins forces with the distribution system operator Stedin. As a member of the Intelligent Electrical Power Grids research group at TU Delft, you will be an affiliated researcher with the ICAI AI for Energy Grids Lab and with Delft AI Energy Lab where we combine ground-breaking AI methods with the reliable theory of the physical energy system. Practically, you will work one day a week at Stedin, where you will be supported by around 5 scientific staff, data scientists and power system experts.

About the department at TU Delft:
The research in the Department of Electrical Sustainable Energy is inspired by the technical, scientific, and societal challenges originating from the transition towards a more sustainable society and focuses on four areas:

• DC Systems, Energy Conversion and Storage (DCE&S)
• Photovoltaic Materials and Devices (PVMD)
• Intelligent Electrical Power Grids (IEPG)
• High Voltage Technologies (HVT)

The Electrical Sustainable Energy Department provides expertise in each of these areas throughout the entire energy system chain. The department owns a large ESP laboratory assembling High Voltage testing, DC Grids testing environment, and a large RTDS that is actively used for real-time simulation of future electrical power systems, AC and DC protection, and wide-area monitoring and protection.

The Intelligent Electrical Power Grid (IEPG) group, headed by Professor Peter Palensky, works on the future of our power system. The goal is to generate, transmit and use electrical energy in a highly reliable, efficient, stable, clean, affordable, and safe way. IEPG integrates new power technologies and smart controls, which interact with other systems and allow for more distributed and variable generation.

Job requirements

At TU Delft we embrace diversity as one of our core values and we actively engage to be a university where you feel at home and can flourish. We value different perspectives and qualities. We believe this makes our work more innovative, the TU Delft community more vibrant and the world more just. Together, we imagine, invent and create solutions using technology to have a positive impact on a global scale. That is why we invite you to apply. Your application will receive fair consideration.

Challenge. Change. Impact!

Faculty of Electrical Engineering, Mathematics and Computer Science
The Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) brings together three scientific disciplines. Combined, they reinforce each other and are the driving force behind the technology we all use in our daily lives. Technology such as the electricity grid, which our faculty is helping to make completely sustainable and future-proof. At the same time, we are developing the chips and sensors of the future, whilst also setting the foundations for the software technologies to run on this new generation of equipment – which of course includes AI. Meanwhile we are pushing the limits of applied mathematics, for example mapping out disease processes using single cell data, and using mathematics to simulate gigantic ash plumes after a volcanic eruption. In other words: there is plenty of room at the faculty for ground-breaking research. We educate innovative engineers and have excellent labs and facilities that underline our strong international position. In total, more than 1000 employees and 4,000 students work and study in this innovative environment.
