چکیده
This study addresses the output impedance model of LCL-type grid-connected converter considering dead-time effects and digital control delay. The shows that delay will affect accuracy converter, are only equivalent to superimposing a disturbance voltage on original model. derived is verified by comparing it with switching in PSIM simulation environment. harmonic interaction between cluster utility grid modeled analyzed based A combined suppression strategy incorporated into every scheme suppress interaction. Simulation results presented demonstrate correctness analysis effectiveness proposed strategy.
