Notice of Retraction Study of Control Strategy on Small Power Photovoltaic Grid-Connected Generation System

Photovoltaic (PV) grid-connected system is the development trend of photovoltaic systems. According to the PV grid-connected system characteristics, analyzes the PV grid-connected inverter control and maximum power point tracking (MPPT) control strategy based on two-stage power conversion architecture, proposed a novel MPPT control algorithm, presents the design of a photovoltaic grid-connected inverse system based on the digital signal processor TMS320F2407. The experiment results verify that the system can track the maximum power point quickly, the grid-connected current wave achieves our need and the wave of grid-connected current has the same frequency and phase as the utility voltage.
