Abstract
Nowadays, transmission system operators require higher degree of observability in real-time to gain situational awareness and improve the decision-making process to guarantee a safe and reliable operation. Digitalization of energy systems allows utilities to monitor the system dynamic performance in real-time at fast time scales. The use of such technologies has unlocked new opportunities to introduce new data driven algorithms for improving the stability assessment and control of the system. Motivated by these challenges, a group of experts have worked together to highlight and establish a baseline set of these common concerns, which can be used as motivation to propose innovative analytics and data-driven solutions. In this document, the results of a survey on 10 transmission system operators around the world are presented and it aims to understand the current practices of the participating companies, in terms of data acquisition, handling, storage, modelling and analytics. The overall objective of this document is to capture the actual needs from the interviewed utilities, thereby laying the groundwork for setting valid assumptions for the development of advanced algorithms in this field.

The authors would like to thank the IEEE TF members involved for their valuable discussions and suggestions during meetings. Moreover, we would like to express our gratitude to all transmission system operators who provided their expertise, know-how and time for participating in the survey voluntarily. It was only thanks to them that it was possible to provide a real insight that greatly assisted the information provided on this document. Finally, the authors also thank the anonymous reviewers for helping us to improve the quality of the final document.
