Electromagnetically Compatible and Virtual Flux DPC Control Techniques for 3-Phase Distributed Generation Fed by Active Rectifier

This paper gives different control mechanisms comparison for active rectifiers fed grid connected 3-phase distributed generation systems from non-conventional energy sources. The control strategies presented here are Direct Power Control, 2 other DPC methods DPC to reduce CM voltage emissions that are EMC-I-DPC and EMC-II-DPC. Another two strategies are also presented with a concept of virtual flux i.e EMC-I-VF-DPC and EMC-II-VF-DPC. MATLAB/Simulink software is used to implement the so called techniques and the parameters like are injected current into electric grid , %Total harmonic distortion of current injected vs. generated power, %Total harmonic distortion of current injected vs DC link voltage (Vdc) and %Total harmonic distortion of current injected vs CM voltages are shown.
