1. An electric power selling system comprising:

  • a plurality of power generators respectively provided for a plurality of houses, each of plurality of power generators generates electric power; and

    a plurality of voltage conversion devices each of which is connected with a corresponding one of the power generators and a distribution line provided between the houses and which is configured to convert output voltage of the corresponding one of the power generators into variable voltage for electric power selling, the plurality of voltage conversion devices respectively provided for the plurality of houses,wherein the electric power selling system further comprises a transmitter connected with the distribution line, the transmitter being configured to measure voltage of the distribution line and to supply the plurality of voltage conversion devices with an instruction value obtained based on the measured voltage value, andwherein each of the voltage conversion devices has a set of candidate voltage values that respectively correspond to voltage steps of equal voltage amount from a lowest one of the candidate target voltage values, each of the voltage conversion devices selects, when receiving the instruction value, a target voltage value which is higher than and closest to the instruction value and converts the output voltage of the corresponding one of the power generators into the voltage for electric power selling based on the selected target voltage value.
