Title: Digital Twins of Strategic Assets in Power Generation and Transmission
Speaker: Prof. Denis Thibault (Hydro Quebec)
Abstract:
The increasing complexity, aging, and criticality of power generation infrastructures require a paradigm shift in asset management, moving from reactive and experience-based practices toward data-driven, predictive, and prescriptive decision-making. Digital twins have emerged as a foundational technology enabling this transition by coupling physics-based models, advanced analytics, and monitoring data within a common framework.
This keynote presents Hydro-Québec’s research and development vision, scope, and implementation strategy for behavioral digital twins of energy assets, with a particular focus on power generation assets. A digital twin is defined as an evolving virtual representation of a physical asset that integrates high-fidelity simulations, reduced-order models, artificial intelligence, and continuously updated field data to monitor, diagnose, predict, and optimize asset behavior throughout its lifecycle.
The presentation introduces a structured digital twin maturity framework ranging from independent and descriptive models to diagnostic, prognostic, prescriptive, and ultimately autonomous systems. Core enabling components are discussed in relation to operational applications such as anomaly detection, remaining useful life estimation and optimized maintenance. Concrete examples of short- and mid-term implementations are provided, notably digital twins for hydroelectric generating units. The keynote outlines ongoing R&D activities supporting this effort, emphasizing the role of digital twins as a strategic lever for maximizing asset utilization and economically optimizing energy systems.
