Through PhD theses and collaborative projects, with public as well as private partners, our Unit carries out researches in six main topics

  • SMART GRIDS AND MICRO-GRIDS

    Research in micro-grids mainly focuses on their interaction with external stakeholders. The idea is to see how the regulatory framework as well as the management rules of the micro-grid can impact other actors and can be adapted to reach a global social welfare. To realize such studies, Game Theoretical approaches are used and adapted in a stochastic multi-agent problem formulation.

    Concerning smart grids, different topics are treated going from centralized voltage control in Medium Voltage Distribution Networks to the development of a long-term techno-economic software that analyses solutions aiming at promoting the penetration of PV generation within Low Voltage Networks.

  • Net Zero Energy Buildings and Districts

    A high building or district performance can only be guaranteed by a well-managed and controlled energy system. Hence, our research work in this topic is with the development of scheduling and control algorithm for Energy Management Systems (EMS) models using renewable energy resources and distributed generation units. The EMS models are formulated as optimisation problems and time step programming is used to optimally address their operation and control.

  • Renewable Energies AND STORAGES SYSTEMS

    Both topics are covered by the unit. Concerning renewable energies, the effort is devoted to modeling aspects. In that context, prediction (at different time horizons) tools as well as methods allowing to deal with incomplete or huge databases are implemented and are based on the use of mathematical techniques like ANN, time series, matrix factorization,etc.

    From the storage point of view, their profitability by providing flexibility within an ARP portfolio is investigated. To do so, a medium term multi-markets optimization problem is formulated and adequately incorporates the impact of shorter-term constraints.

  • Wireless Power Transfer Using Resonant Inductive Coupling

    Wireless Power Transfer (WPT) is nowadays a trending research topic, boosted by the continuous progress made in power electronics. Today, high power is generated at high frequencies, paving the way to the implementation of WPT to high power applications, such as the electric vehicle battery charging. Our Unit conducts research to provide adapted and original computational electromagnetic methods for the modeling of WPT coils. In this context, the Finite Element method combined with surface impedance boundary conditions and the Partial Element Equivalent Circuit are employed. Moreover, attention is drawn on the elaboration and on the control of power electronic converters surrounding the coils in order to optimize the transfer performances. Source soft-switching operation and load modulation are implemented for doing so.*

  • Power Electronics for Railways and Space Applications

    Research in power electronics is mainly focused on dc-dc conversion, including hard and soft-switching topologies. The design, optimisation and control problems are treated, considering also the potential offered in terms of mass and power loss reduction by the use of new wide band gap semiconductor (SiC and GaN) devices. The targeted applications are mostly with: auxiliary railway power supplies, switch-mode power supply for space applications, and more recently electric vehicle battery wireless chargers.

  • Modeling of Electromagnetic Devices Using Numerical Methods

    Computational electromagnetics aim at solving numerically the Maxwell equations on geometrical representations of electrical devices, so as to provide local (e.g. field intensity in a particular point of the device) and global quantities (e.g. a current, a voltage or a force), useful for the engineer. Our team conduct advanced research on Finite Element and Integral methods as well (Boundary Element Method, Partial Element Equivalent Circuit method). A particular emphasis is put on:

     

    • Systems operating at intermediate frequencies (from several kHz to several MHz), for Wireless Power Transfer and conducted ElectroMagnetic Compatibiliy (EMC) problems for instance

    • The modeling of the unavoidable uncertainties arising when setting up a model (such as geometrical and material parameters uncertainties)

    • The homogenization of electromagnetic fields in presence of periodical structures such as windings

    • The exploitation of geometrical and material symmetries in the field problems using Group Representation Theory

    • The modeling of non linear materials such as power transformer Fe-Si alloys or ferrite materials
