    • Nonlinear optimal large-scale structures in turbulent channel flow 
      Article dans une revue avec comité de lecture
      FARANO, Mirko; CHERUBINI, Stefania; DE PALMA, Pietro; ccROBINET, Jean-Christophe (Elsevier, 2018)
      Coherent structures in turbulent shear flows take the form of packets of hairpin vortices reaching the outer region of the boundary layer along with streaks of different size, going from the near-wall to the outer region. ...
    • In Vivo Assessment of Elasticity of Child Rib Cortical Bone Using Quantitative Computed Tomography 
      Article dans une revue avec comité de lecture
      ZHU, Y.; BERMOND, François; PAYEN DE LA GARANDERIE, J.; PIALAT, J.-B.; ccSANDOZ, Baptiste; BRIZARD, D.; PRACROS, J.-P.; RONGIERAS, F.; ccSKALLI, Wafa; MITTON, David (Hindawi, 2017)
      Elasticity of the child rib cortical bone is poorly known due to the difficulties in obtaining specimens to perform conventional tests. It was shown on the femoral cortical bone that elasticity is strongly correlated with ...
    • Direct AC Voltage Control for Grid-Forming Inverters 
      Article dans une revue avec comité de lecture
      QORAI, Taoufik; LI, Chuanyue; OUE, Ko; COLAS, Frédéric; GUILLAUD, Xavier; ccGRUSON, Francois (2019)
      Grid-forming inverters usually use inner cascaded controllers to regulate output AC voltage and converter output current. However, at the power transmission system level where the power inverter bandwidth is limited, i.e., ...
    • Critical clearing time determination and enhancement of grid-forming converters embedding virtual impedance as current limitation algorithm 
      Article dans une revue avec comité de lecture
      QORIA, Taoufik; COLAS, Frédéric; DENIS, Guillaume; PREVOST, Thibault; GUILLAUD, Xavier; ccGRUSON, Francois (Institute of Electrical and Electronics Engineers, 2019)
      The present paper deals with the post-fault synchronization of a voltage source converter based on the droop control. In case of large disturbances on the grid, the current is limited via current limitation algorithms such ...
    • Embedding OLTC nonlinearities in predictive Volt Var Control for active distribution networks 
      Article dans une revue avec comité de lecture
      MORIN, J.; COLAS, Frédéric; DIEULOT, Jean-Yves; GRENARD, S.; GUILLAUD, Xavier (Elsevier, 2017)
      Volatile productions and consumptions generate a stochastic behavior of distribution grids and make its supervision difficult to achieve. Usually, the Distributed Generators reactive powers are adjusted to perform decentralized ...
    • Preparation of new proton exchange membranes using sulfonated poly(ether sulfone) modified by octylamine (SPESOS) 
      Article dans une revue avec comité de lecture
      MABROUK, Walid; OGIER, Lionel; SOLLOGOUB, Cyrille; VIDAL, Serge; DACHRAOUI, M.; FAUVARQUE, J.F (Elsevier, 2011)
      Sulfonated poly(arylene ether sulfone) (SPES) has received considerable attention in membrane preparation for proton exchange membrane fuel cell (PEMFC). But such membranes are brittle and difficult to handle in operation. ...
    • Stochastic Optimization of PQ Powers at the Interface between Distribution and Transmission Grids 
      Article dans une revue avec comité de lecture
      BUIRE, Jérôme; COLAS, Frédéric; DIEULOT, Jean-Yves; GUILLAUD, Xavier (MDPI, 2019)
      This paper addresses the volt-var control of distribution grids embedding many distributed generators (DGs). Specifically, it focuses on the compliance of powers to specified PQ diagrams at the high voltage/medium voltage ...
