Abstract
This paper presents a new direct active and reactive power control (DPC) controller scheme for a three-phase grid connected voltage source inverter (VSI) based on passivity viewpoint. The proposed method is designed in the framework of port-controlled Hamiltonian system. The proposed method is made up of two parts, one thing is a feedfoward part and the other is a feedback part. The feedforward part is calculated from the model dynamics of VSI. The feedback part is designed to compensate for system uncertainty. The proposed method is verified with simulation and experiment. The simulation uses MATLAB/Simulink and PLECS, and the experiment uses hardware in the loop (HIL) with TI TMS320F28335 DSP. The simulation and experiment results compared with those using direct power control-sliding mode control (DPC-SMC) for the grid connected VSI. The proposed method gives less total harmonic distortions, faster transient response. © 2015 IEEE.
