说明：  该仿真模型基于重复控制算法，对逆变器的并网控制进行了详细的仿真，方便熟悉该算法的工作原理及逆变器的工作原理。
(The simulation model is based on the repetitive control algorithm, and the grid-connected control of the inverter is simulated in detail, which is convenient to familiarize with the working principle of the algorithm and the working principle of the inverter.)
