Abstract: Firstly, this paper introduces the operational principle and performance characteristic of photovoltaic cells, and describes the equivalent circuit and mathematical model. Secondly, this paper introduces several traditional MPPT control algorithms. Based on the maximum power of the fast track process and stability, an improved intermittent scan method is designed to implement the maximum power output in the photovoltaic grid-connection generation system and improve system performance and maximum power point tracking speed. Finally, this dissertation analyses the targets of grid-connected inverter control and studies the control strategies.
