JOURNAL OF MODERN POWER SYSTEMS AND CLEAN ENERGY

Abstract
This paper provides an overview of the application potential of artificial intelligence (AI) in power systems and points towards prospective developments in the fields of AI that are promised to play a transformative role in the evolution of power systems. Among the basic requirements, also imposed by regulation in some places, are trustworthiness and interpretability. Large language models, foundation models, as well as neuro-symbolic and compound AI models, appear to be the most promising emerging AI paradigms. Finally, the trajectories along which the future of AI in power systems might evolve are discussed, and conclusions are drawn.

Abstract
This paper examines the effectiveness of various synthetic data generation methods for deterministic wind power forecasting. Specifically, this work evaluates four approaches - Gaussian Mixture Models (GMMs), t-Copula, DoppelGANger, and FCPFlow - by comparing the forecasting performance, measured using Mean Absolute Error and Root Mean Squared Error, of models trained on synthetic versus real datasets. Our findings indicate that statistical methods (such as GMM and t-Copula) achieve notably better performance under limited data availability. However, the deep generative model FCPFlow yields superior results when sufficient training data is available. These findings suggest that the choice of synthetic data generation method should be informed by the specific data availability context.

Abstract
The interaction between humans and AI in safety-critical systems presents a unique set of challenges that remain partially addressed by existing frameworks. These challenges stem from the complex interplay of requirements for transparency, trust, and explainability, coupled with the necessity for robust and safe decision-making. A framework that holistically integrates human and AI capabilities while addressing these concerns is notably required, bridging the critical gaps in designing, deploying, and maintaining safe and effective systems. This paper proposes a holistic conceptual framework for critical infrastructures by adopting an interdisciplinary approach. It integrates traditionally distinct fields such as mathematics, decision theory, computer science, philosophy, psychology, and cognitive engineering and draws on specialized engineering domains, particularly energy, mobility, and aeronautics. Its flexibility is further demonstrated through a case study on power grid management.
