Abstract:According to the grid-connected photovoltaic(PV)system with nonlinearities, uncertainties, heterogeneous characteristics and so on, the hybrid control theory is applied to the design of maximum power point tracking(MPPT) and grid-connected inverter control strategy in this paper. Firstly, the hybrid control theory is introduced and the hybrid characteristics of rid-connected PV system are analyzed. Then, the hybrid control decision of MPPT and grid-connected inverter are respectively designed and control model of rid-connected PV system based on hybrid automata is established. Finally, through the simulation results to prove the model and method is correct and effective. Simulation results show that the control method can achieve MPPT rapidly and grid-connected current tracking power grid voltage accurately.
