| Abstract: | The PV grid-connected inverter hybrid features were analyzed,and the hybrid automata theory was summarized. Based on the hybrid automata model of grid-connected inverter and the design of hybrid controller,a grid-connected control strategy was proposed. Through the Simulink and Stateflow toolbox of MATLAB simulation platform,the correctness and effectiveness of the theory was verified. The simulation results show that the PV gridconnected inverter with the proposed control method can not only achieve normal grid-connected functions,but compensate certain reactive current and harmonic current. |
