Objectives: Power electronic converters are usually utilized for interfacing Distributed Generation (DG) resources to power grids. This paper proposes a novel and simple control technique for connection of DG resources to Three-Phase Four-Wire (3P4W) distribution grids via interfaced converters. Methods: The differential equations of the DG system are established, and then the switching state functions of the grid-interfacing converter are achieved in order to improve the transient response of system and power quality of grid. Results: By means of the proposed approach, the grid-interfacing converter can transfer active power at main frequency from DG resources to grid, and also compensate all reactive, neutral, harmonic and unbalanced load current components with a fast transient waveform. Applications: The effectiveness of the proposed control technique is demonstrated by the simulation studies in MATLAB/Simaulink environment.
