DESCRIPTION:Dr. Arthur Favrel\, Hydro-Quebec Research Institute (IREQ) and
  Laval University (Canada)\nAbstract: Hydropower is playing a pivotal role
  in the energy transition by providing clean energy and advanced ancillary
  services to the Electrical Power System (EPS) to compensate for the volat
 ility of wind and solar energy sources. This role requires enhanced operat
 ional flexibility\, which translates to more frequent transient and off-de
 sign operations. In such operating conditions\, hydropower units with reac
 tion turbines sustain various unsteady flow phenomena\, putting at risk th
 e stability and integrity of the hydro-mechanical and electrical component
 s. Prediction of these occurrences is therefore crucial to ensure reliable
  operations while providing ancillary services to the EPS. In the first pa
 rt of this presentation\, various flow phenomena observed in reaction hydr
 o-turbines will be first described and illustrated\, along with their effe
 cts on hydropower unit’s components\, highlighting some of the latest wo
 rks in this field. In the second part\, it will be shown how the occurrenc
 e of flow-induced resonances in full-scale hydropower units can be predict
 ed by combining reduced-scale model tests in laboratories and one-dimensio
 nal hydro-acoustic modelling. Finally\, the detection and characterization
  of such phenomena through data-driven methods in the context of a hydropo
 wer utility will be discussed\, concluding with new research perspectives 
 for hydropower digitalization and flexibility enhancement.\n\nBiography: A
 rthur Favrel is a researcher at the Hydro-Quebec Research Institute in Can
 ada and an Adjunct Professor at Laval University (Canada). He is also an A
 ssociate Editor for the Journal of Fluids Engineering published by the Ame
 rican Society of Mechanical Engineers (ASME). He graduated in mechanical e
 ngineering in 2011 from Université Claude Bernard in Lyon\, France\, and 
 obtained his PhD in 2016 from École polytechnique fédérale de Lausanne\
 , Switzerland. After two years as a postdoctoral researcher at the EPFL La
 boratory for Hydraulic Machines\, he joined Waseda University\, Japan\, in
  2018 as a postdoctoral researcher in the Turbomachinery and Systems Labor
 atory\, where he then became an Assistant Professor in 2019. In his curren
 t function at Hydro-Quebec since 2021\, his research aims to develop digit
 al twins of hydropower units’ components for advanced asset management b
 y combining data-driven methods and physics-based models. He is the author
  and co-author of 25 articles in international journals and 30 conference 
 papers and is a contributor to the IEC Technical Specification 62882 publi
 shed in 2020.
