1. A distributed photovoltaic system, comprising:
N first photovoltaic modules each configured to convert solar energy into direct current power;
N energy storage modules; and
N inverters, wherein
N is a positive integer;
output terminals of the N first photovoltaic modules are connected to input terminals of the N energy storage modules in one-to-one correspondence, output terminals of the N energy storage modules are connected to first input terminals of the N inverters in one-to-one correspondence, output terminals of the N inverters are connected in parallel at a joint configured to connect a power grid or load;
the N energy storage modules each are configured to store direct current power obtained through conversion by the first photovoltaic module connected to the energy storage module and supply the stored direct current power to the inverter connected to the energy storage module; and
the N inverters each are configured to convert the direct current power into alternating current power and supply the alternating current power to the grid or load for use.
