A photovoltaic grid-connected system is a device that converts the direct current generated by a solar panel into a sinusoidal alternating current to supply power to the grid, which is actually an active inverter system. The control goal of the photovoltaic grid connected inverter is to control the output current of the inverter circuit to be a stable high-quality sine wave, and the same frequency and phase as the grid voltage. Photovoltaic grid-connected system inverters are classified according to control methods and can be divided into voltage source voltage control, voltage source current control, current source voltage control and current source current control. The voltage source inverter uses a capacitor as an energy storage component, and a large capacitor connected in parallel on the DC input side is used as a reactive power buffer link to constitute a low impedance power supply internal resistance characteristic of the inverter, that is, a voltage source characteristic. Inverter with current source as input mode, the DC side needs to be connected in series with a large inductor as the reactive component to store reactive power, which constitutes the high-impedance current source characteristic of the inverter, and provides stable DC current input, but the serial input is large. Inductance often leads to poor dynamic response of the system. Therefore, most PV grid-connected inverters in the world use voltage source input as the main method.
