Title: Prognostics and Health Management via Recurrent Expansion: Exploring Deeper Representations than Deep Learning

Keynote Speaker:

Dr. Mohamed Benbouzid, IEEE Fellow, IET Fellow, Professor, University of Brest, France


Machine learning applications for prognosis and health management usually face data unavailability, complexity, and drift due to the massive and rapid evolution of data volume,velocity, and variety (3V). Advances in deep learning have brought many improvements in this area, providing generative modelling, nonlinear abstractions, and adaptive learning to meet these challenges. Deep learning aims to learn from representations that provide a coherent abstraction of the original feature space, enabling it to be more meaningful and less complex. However, the data complexity associated with various distortions, such as higher noise levels, remains challenging to overcome. In this context, recurrent expansion algorithms have recently been introduced to explore deeper representations than ordinary deep networks, enabling even better feature mapping. In contrast to traditional deep learning, where abstracting inputs extract meaningful representations, recurrent expansion merges entire deep networks into one, allowing inputs, maps, and estimated targets to be explored as primary sources of learning. These three sources of information provide additional knowledge about their interactions in a deep network.

Furthermore, recurrent expansion provides the ability to investigate the estimated targets of multiple networks and learn significant features, improving its accuracy with each round.

This keynote will provide a general overview of recurrent expansion, its main learning rules, variants, and prospective developments in this context. Case studies on electromechanical systems will be provided to illustrate the effectiveness of recurrent expansion prognosis.

Title: Research Progress of Prognostics and Health Management Technology for Power Conversion System

Keynote Speaker:

Dr. Y. Q. Chen, Deputy Chief Engineer of National Key Laboratory, The No.5 Electronics Research Institute of the Ministry of Industry and Information Technology, China



Power conversion system (PCS), such as electric drive and power supply, is the“Heart” of smart and electric equipment, such as aircraft, high-speed train and automobile and so on. And the reliability of the PCS is very important. There are some defects about the traditional reliability assurance methods based on pre-life prediction and post-failure analysis, such as high cost, low efficiency and poor accuracy. Prognostics and health management (PHM) technology is based on failure physics, which is used to predict and evaluate the reliability of a product in a real environment, and major accidents may be avoided. This report reviews the development status and quality reliability problems of PCS at first. Then, introduces the research progress of the physics of failure for the key devices of PCS. Next, expounds the research progress of the sensing and predication technology for the failure of PCS. At Last, shows the applications cases of PHM technology for the PCS.

Title: Industrial Challenges and Current Research with the Green Energy Transition

Keynote Speakers:

Carl-Maikel Högström, Program Manager, Vattenfall R&D laboratory in Älvkarleby, Sweden

Ryad Zemouri, Data Scientist, Hydro-Québec, Canada


Power grids are changing rapidly, requiring a revision of their architecture, planning and operation to maintain stability and security in a context of increasing variability and uncertainty. This change requires an increase in the number of physical variables to be measured and monitored. In addition, the rapid expansion of renewable energy sources, increasing demand for electricity, and the need to improve grid reliability have necessitated the development of advanced technologies for managing power generation and transmission assets. As a result, the electric power sector is facing several operational challenges. In this presentation, we'll explore the industrial and technological context we face today in the energy sector. What are the challenges and current research with the green energy transition in terms of modeling, experimentation, and deep learning algorithms. Two industrial contexts will be illustrated: the North American context, presented by Hydro-Quebec, and the European context, presented by Vattenfall AB, R&D.
