Photovoltaic power station structure integrating charging, discharging, storage, replacing functions

The utility model discloses a photovoltaic power station structure integrating charging, discharging, storage, replacing functions. The photovoltaic power station structure comprises a solar device, which converses acquired solar energy into electric energy and DC is output to a photovoltaic combiner box. The photovoltaic combiner box is connected with a DC/DC module through a DC bus, the DC/DC module is connected with an energy storage battery, and the energy storage battery transmits energy to an AC bus through an energy conversion system. The AC bus is connected with a power distribution network and a charger, the charger is connected with a power battery, and the power battery is connected with the AC bus through a grid connected current transformer. The photovoltaic power station structure, based on the storage and discharging functions of a power battery and an energy storage battery, acquires electric energy from the power grid during low-power consumption time and feeds electric energy back to the power grid during peak hours to balance power consumption and make the power grid run smoother.
