Abstract	Owing to the numerous non-linear and reactive local loads, the applied grid-tied inverters etc., the quality of power supply of micro-grids becomes a challenging issue need to be highly addressed. As the power quality can significantly affect the secure, stable, effective and economic operation of the micro-grids, the compensation of the harmonic and reactive current in the micro-grids by the use of power quality conditioners and/or advanced control strategies has been highlighted. In this study, the multi-functional grid-tied inverters (MFGTIs) are attempted to interface renewable energy resources and enhance the power quality within the micro-grid. The MFGTIs encompassed with the coordinated control strategy based on the Fryze–Buchholz–Dpenbrock (FBD) theory. Through limiting the harmonic and reactive conductance and susceptance detected by FBD theory, the harmonic and reactive current within the micro-grid can be shared among the MFGTIs in a coordinated and automatic fashion in accordance with their capacities without communication. A set of the experiments based on the micro-grid test-bed are carried out and the results confirm the effectiveness and feasibility of the suggested control strategies.
