摘要：
Grid-Connected Inverter (GCI) is used for energy conversion from a DC source to an AC source. GCI also is the key part in the distributed energy grid-connected system. Sliding mode control (SMC) has good dynamic response, strong robustness, especially for nonlinear systems. This paper presents a new SMC method based on the energy state of the inverter, converting the control target of the circuit from electrical parameter to circuit energy state by establishing the energy model of LCL-type single-phase GCI and analyzing the stability of LCL filter. Simulation results show the effectiveness of proposed control strategy.
