Simulation of the LCL-type Grid-connected Inverter Design Applied to Photovoltaic Power Generation
In order to improve the stability of the out-put power of the grid-connected inverter,a dual-loop con-trol strategy model is established,while the resonance spike problem of the LCL-type filter is suppressed by the method of capacitor series resistance in the passive damping meth-ods.Using MATLAB/Simulink,a PV grid-connected in-verter system model is built for simulation and verification.The results show that the scheme has strong anti-interfer-ence ability,further more,the grid-connected current and grid voltage are basically in phase,to realize the grid-con-nection with unit power factor and has good stability.
