Abstract
Based on the analysis of structure and common control scheme of photovoltaic grid-connected system, a solar photovoltaic (PV) cell simulation model is built according to the internal structure and output characteristics of PV cell. A control method of photovoltaic MPPT which can track photovoltaic points and the maximum power of photovoltaic cells is expounded. This method can be used to improve the efficiency of photovoltaic cells to the greatest extent. Finally, the principle and control strategy of the photovoltaic grid-connected system are analyzed in detail. According to the instantaneous value control method of grid-connected inverter, some requirements of grid connection with low THD and high power factor are achieved.
