英文摘要	The LLCL filter is widely used in grid-tied inverter systems due to its small size, low cost and good attenuation for high-frequency harmonics. However, the LLCL filter resonance phenomenon and the wide range of impedance may compromise the system stability. In order to solve these problems, a coordination control strategy for LLCL-filter-based grid-tied inverter with indirect sliding mode power control and virtual impedance was presented. The LLCL filter design parameter has been carefully adjusted to ensure the system stable operation under a wide range of grid impedance variations. Comparing with the traditional proportional integral control system through simulation experiment, the output current harmonics of grid-tied inverter are analysed. The proposed strategy is feasible with good control accuracy and tracking performance.
