摘要

提出了一种具有非线性负载的重复控制器控制单相微电网变换器系统。选择常规RC (CRC)和添加在命题控制器中的4k±1阶谐波RC (4Ä±1阶RC)作为控制器，实现微电网直流侧与负载之间的功率平衡、单位功率因数、零误差电网电流跟踪其参考。此外，4k±1 RC比CRC具有更快的网格电流误差收敛速度。最后，以具有非线性负载的4k±1 RC控制单相微电网变换器系统为例，验证了该方法的有效性和优越性。

Ak±1-order harmonic repetitive controller for single-phase micro-grid power converter system with nonlinear loads

This paper proposed the repetitive controller (RC) controlled single-phase micro-grid power converter system with nonlinear load. Conventional RC (CRC) and 4k±1-order harmonic RC (4Ä±1 RC) added into a propositional controller are chosen as the controllers to achieve micro-grid power balance between dc-side and load, unit power factor, and zero-error grid current tracking its reference. Moreover, 4k±1 RC has faster grid current error convergence rate than CRC. Finally, a simulation example of 4k±1 RC controlled single-phase micro-grid power converter system with nonlinear load is provided to verify its effectiveness and advantageous.
