  • active Power management of multihybrid fuel cell supercapacitor Power Conversion System in a medium voltage microgrid
    IEEE Transactions on Smart Grid, 2012
    Co-Authors: Amin Ghazanfari, Mohsen Hamzeh, Hossein Mokhtari, Houshang Karimi
    Abstract:

    This paper proposes a hierarchical active Power management strategy for a medium voltage (MV) islanded microgrid including a multihybrid Power Conversion System (MHPCS). To guarantee excellent Power management, a modular Power Conversion System is realized by parallel connection of small MHPCS units. The hybrid System includes fuel cells (FC) as main and supercapacitors (SC) as complementary Power sources. The SC energy storage compensates the slow transient response of the FC stack and supports the FC to meet the grid Power demand. The proposed control strategy of the MHPCS comprises three control loops; dc-link voltage controller, Power management controller, and load current sharing controller. Each distributed generation (DG) unit uses an adaptive proportional resonance (PR) controller for regulating the load voltage, and a droop control strategy for average Power sharing among the DG units. The performance of the proposed control strategy is verified by using digital time-domain simulation studies in the PSCAD/EMTDC software environment.

  • a grid connected photovoltaic Power Conversion System with single phase multilevel inverter
    Solar Energy, 2010
    Co-Authors: Sabri Camur, Birol Arifoglu, Ersoy Beser
    Abstract:

    This paper presents a grid-connected photovoltaic (PV) Power Conversion System based on a single-phase multilevel inverter. The proposed System fundamentally consists of PV arrays and a single-phase multilevel inverter structure. First, configuration and structural parts of the PV assisted inverter System are introduced in detail. To produce reference output voltage waves, a simple switching strategy based on calculating switching angles is improved. By calculated switching angles, the reference signal is produced as a multilevel shaped output voltage wave. The control algorithm and operational principles of the proposed System are explained. Operating PV arrays in the same load condition is a considerable point; therefore a simulation study is performed to arrange the PV arrays. After determining the number and connection types of the PV arrays, the System is configured through the arrangement of the PV arrays. The validity of the proposed System is verified through simulations and experimental study. The results demonstrate that the System can achieve lower total harmonic distortion (THD) on the output voltage and load current, and it is capable of operating synchronous and transferring Power values having different characteristic to the grid. Hence, it is suitable to use the proposed configuration as a PV Power Conversion System in various applications.
