  • decentralized method for load sharing and power management in a hybrid single three phase islanded microgrid consisting of hybrid source pv battery units
    IEEE Transactions on Power Electronics, 2017
    Co-Authors: Yaser Karimi, Hashem Oraee, Josep M Guerrero
    Abstract:

    This paper proposes a new decentralized power management and load sharing method for a photovoltaic (PV)-based, hybrid single/three-phase-islanded microgrid consisting of various PV units, battery units, and hybrid PV/battery units. The proposed method is not limited to the systems with separate PV and battery units, and power flow among different phases is performed automatically through three-phase units. The proposed method takes into account the available PV power and battery conditions of the units to share the load among them. To cover all possible conditions of the microgrid, the operation of each unit is divided into five states in single-phase units and seven states in three-phase units and modified active power-Frequency droop functions are used according to operating states. The Frequency Level is used as trigger for switching between the states. Efficacy of the proposed method in different load, PV generation and battery conditions is validated experimentally in a microgrid lab prototype consisting of one three-phase unit and two single-phase units.

  • decentralized method for load sharing and power management in a pv battery hybrid source islanded microgrid
    IEEE Transactions on Power Electronics, 2017
    Co-Authors: Yaser Karimi, Hashem Oraee, Mohammad S Golsorkhi, Josep M Guerrero
    Abstract:

    This paper proposes a new decentralized power management and load sharing method for a photovoltaic based islanded microgrid consisting of various photovoltaic (PV) units, battery units and hybrid PV/battery units. Unlike the previous methods in the literature, there is no need to communication among the units and the proposed method is not limited to the systems with separate PV and battery units or systems with only one hybrid unit. The proposed method takes into account the available PV power and battery conditions of the units to share the load among them. To cover all possible conditions of the microgrid, the operation of each unit is divided into five states and modified active power-Frequency droop functions are used according to operating states. The Frequency Level is used as trigger for switching between the states. Efficacy of the proposed method under different load, PV generation, and battery conditions is validated experimentally in a microgrid lab prototype consisting of three units.

  • An experimental study on vibration isolation performance of weft-knitted spacer fabrics
    SAGE Publications, 2016
    Co-Authors: Chen F, Liu Y, Hu H
    Abstract:

    This paper presents an experimental study on the vibration isolation performance of weft-knitted spacer fabrics under forced harmonic excitation. The weft-knitted spacer fabrics with two different thicknesses were first designed by varying the linking distance of the spacer monofilament and fabricated using an electronic flat knitting machine. Then, their vibration isolation performance was tested under forced vibration condition via sinusoidal sweeps from low to high frequencies. The typical acceleration transmissibility curve and effects of fabric thickness, load mass and excitation Level were discussed in detail. The results obtained show that the thicker spacer fabric has a lower resonance Frequency than the thinner fabric due to lower stiffness, and thus can isolate the vibration at a lower Frequency Level. The results also show that changing the load mass and excitation Level changes the loading conditions of the fabric structure, and thus also changes fabric stiffness and vibration isolation performance due to nonlinear behavior of spacer fabrics. It is expected that this study could provide some useful information to promote the application of weft-knitted spacer fabrics for vibration isolation.Institute of Textiles and Clothin
