1. A space photovoltaic generation system comprising:

  • a plurality of power generation satellites each having;

    a photoelectric conversion unit for converting sunlight into electric energy;

    a transmission frequency conversion unit for performing frequency conversion of the electric energy provided by the photoelectric conversion unit to a microwave;

    a microwave control unit for controlling at least one of the amplitude and the phase of the microwave output by the transmission frequency conversion unit; and

    a transmitting antenna for radiating the microwave, and a power base having;

    a receiving antenna for receiving the microwave radiated from the power generation satellites; and

    a reception frequency conversion unit for performing frequency conversion of the microwave received at the receiving antenna to one of DC and low-frequency commercial power, wherein the plurality of power generation satellites are placed in space to form a power generation satellite group; and

    wherein a first array antenna having the transmitting antennas of the power generation satellites in the power generation satellite group as element antennas is formed.
