PROBLEM TO BE SOLVED: To provide a distributed power supply system in which surplus power can be surely processed while suppressing device expansion or weight increase.SOLUTION: In the distributed power supply system, a power generation device 20 supplies the same power to a first voltage line 2a and a second voltage line 2b in such a manner that the total power of power from the side of a first connection point P1 to a second connection point P2 through the first voltage line 2a and power from the side of the first connection point P1 to the second connection point P2 through the second voltage line 2b becomes minimum and does not become negative power. A power conversion section 13 provided in an auxiliary power supply device 10 includes: a first power conversion circuit section 13A performing power conversion between the first voltage line 2a/a neutral line 2c and a power storage section 12; a second power conversion circuit section 13B performing power conversion between the second voltage line 2b/the neutral line 2c and the power storage section 12; and power transfer means 16 capable of transferring power between the first power conversion circuit section 13A and the second power conversion circuit section 13B. |
