摘要：

Microgrid technology can effectively integrate the advantages of new energy and renewable energy generation and provides a novel way for large-scale applications of new energy and renewable energy connecting to grid. PV grid-connected inverter control plays a core and key role in PV interconnected to power grid. First PV grid-connected inverter model is established, which assumes a constant DC voltage, switch states input to avoid the linearization calculation. Based on the linear model, by using the improved virtual flux orientation, a novel decoupling control strategy is proposed for PV grid-connected inverter control to realize the decoupling control of the inverter output power. Finally the simulation result verifies the correctness and validity of this control method.
