Abstract :
This paper presents a strategy for single phase photovoltaic grid-connected control. After proposing the structure and math model of the system. briefly analyses maximum power point tracking algorithm and quasi-sliding mode control principle. Finally introduces the quasi-sliding mode grid-connected control simulation. The simulation results show that: (1) Photovoltaic grid-connected system mode based on quasi-sliding mode control is able to realize inverting power factor closing to 1, (2) The system has the advantages of fast dynamic responsiveness and good steady tracking performance. Thus the feasibility and practicability of the system design are verified.
