Abstract :
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.
