Decentralized power control and management between the utility grid and the microgrid using series transformerless H-bridge inverter.


Since October. 2014: DAAD PhD scholar at the institute of Energy Conversion and Storage, University of Ulm, Germany.

                                   Major Tasks:
                                           - Development of power generation control method based P/V droop
                                              characteristic for the microgrid DGs in time domain.
                                            - Development of power control strategy of the series transformerless
                                               H-bridge inverter as a series power flow controller between the
                                               microgrid and the utility in time domain.
                                            - Validation of the proposed approaches in frequency domain using
                                               overall power flow algorithm and optimization functions.
                                            - Investigation of the islanding and resynchronization process in case
                                               of short circuit events.
