基于准PR控制的并网逆变器具有良好的准确性和抗干扰性能，但是电网电压存在的谐波会使并网电能质量变差。为了改善并网电能质量，采用基于准PR控制和PI复合控制的并网逆变器，在MATLAB/Simulink环境下建立了系统的仿真模型，仿真实验的结果表明：采用该控制的并网逆变器可以基本避免电网电压谐波对并网电能质量的影响，实现并网电流与电网电压的同频同相和并网电流的无静差跟踪，具有良好的控制效果。同时省去了对三相电容电流的检测，很大程度上节约了成本。

Abstract——The distributed power generation systems based on the renewable energy sources, such as solar photovoltaic, wind power, geothermal power, have been the focus of the world in the latest years. The grid-connected inverter is important power electronic implements, used to transfer the power from the DPGS to the public grid, and the quality of its output power has been studied a lot. The repetitive control technique based on the internal model principle, can achieve low steady-state tracking error and total harmonic distortion (THD) in AC systems, so it is widely adopted in the inverter systems. However in the practical applications, there are still some issues needs solving when using the repetitive control technique. To suppress the current distortion, a control strategy of fundamental current and harmonics controlled separately is adopted. On the synchronous rotating coordinate, the fundamental component is direct value and the harmonic component is alternating value. Proportion-integral (PI) values above which can achieved output controlJer and proportion resonant (PR) controller are adopted to control the power adjustment and zero error control of harmonic restrain.

Abstract —— In order to improve adaptability for wind power gridconnected converter under non-ideal grid conditions and reduce the harmonic influence, harmonic suppression mechanism for grid-connected converter is depth analyzed and harmonic suppression method and theory is derived. Be limited by complexity of the control system, compound control strategy composed by repetitive controller paralleled with PI controller is proposed for grid-connected converters control in this paper. System stability is analyzed, Geometric representation for repetitive controller stability is shown in figure and Control system difference equation is deduced. Using the proposed control strategy, no difference tracking current control is achieved in the fundamental positive sequence reference frame. The gird current harmonic can be effectively reduced and the converter grid adaptability is improved. The simulation and experimental results verified the effectiveness of the proposed control strategy.
