چکیده
Abstract In order to further optimize the output current harmonic suppression effect of photovoltaic grid-connected inverters, a composite control strategy LCL type inverter is proposed. This combines proportional complex integral (PCI) and repetitive (RC) in parallel, draws block diagram, introduces transfer function, designs PCI RC parameters. Prove that compound can reduce harmonics, achieved purpose reducing steady-state error fundamental frequency. And adopts new strategy, which helps save cost system. By building MATLAB/Simulink simulation platform establishing PCI+RC model inverter, comparison results shows compared with PI+RC total distortion rate reduced by 25.77. %, significantly improving quality current.
