Multimodal AI and ML Applications for Electric Power Systems

The Department of Electrical Power Engineering and Mechatronics at TalTech invites applications for a fully- funded PhD position in the field of AI applications in electric power systems, with a special emphasis on multimodal AI models and their applications in electric power systems. This interdisciplinary PhD position combines artificial intelligence (AI) and modern electric power systems. The primary objective of the research is to investigate and develop multimodal machine learning models capable of processing heterogeneous data sources—specifically time-series sensor readings, visual data (e.g., images and video streams), and unstructured textual documents. As electric power systems undergo digital transformation, the integration and intelligent analysis of such diverse data modalities are increasingly critical for operational reliability, predictive maintenance, system diagnostics, and grid optimisation. The PhD candidate will contribute to developing robust, interpretable, and scalable AI methodologies tailored to the requirements and constraints of power system applications.

This PhD position offers an exciting opportunity to conduct cutting-edge research in the field of AI applications in electric power systems, with a special focus on applying GPT and DL technologies. The research will aim to develop innovative solutions that leverage the power of AI and machine learning (ML) to enhance the efficiency, reliability, and sustainability of electric power systems.

Digital sensors, monitoring systems, and automated control have resulted in electric power systems generating increasingly diverse and voluminous datasets. These include numerical time-series data from sensors and meters, visual input from drones and surveillance systems, and technical documentation in textual form. The ability to jointly analyse these distinct modalities using multimodal AI and ML models opens new avenues for system resilience, adaptive management, and enhanced situational awareness.

This doctoral research seeks to develop and assess advanced AI architectures capable of fusing multimodal data streams for power system monitoring, diagnostics, and control applications. The focus will be on the design, implementation, and evaluation of deep learning techniques—including, but not limited to, multimodal transformers, graph neural networks, and contrastive learning frameworks—that are attuned to the operational context of electrical infrastructure.

The project will include empirical testing on real and simulated datasets, drawn from smart grid components, substation monitoring systems, and operational reports. Emphasis will be placed on the explainability and robustness of the models, especially in mission-critical decision-support contexts.
