Ground photovoltaic power station refers to the solar photovoltaic power station connected with the public grid and jointly responsible for the power supply task. The ground photovoltaic grid-connected power station is composed of battery array, grid-connected inverter, photovoltaic special integrated intelligent substation, etc. Photovoltaic array converts solar energy directly into electric energy when there is light, converts direct current into alternating current through grid-connected inverter, and then connects to the public power grid after voltage boost through photovoltaic special integrated smart substation, which jointly undertakes the power supply task.
