PROBLEM TO BE SOLVED: To provide a distributed-type power supply system for organically operating a system power supply, a storage battery, and an electric car, which, when there is a system power supply, can make power from the system power supply uniform, and which, when there is no system power supply, can organically operate each storage battery and supply power to a load.SOLUTION: The distributed-type power supply system comprises: a bidirectional DC/DC converter 4 for adjusting DC power from a storage battery 5; a plurality of bidirectional charge/discharge devices 7-1 to 7-5 for adjusting the DC power inputted/outputted to and from a plurality of electric cars 6-1 to 6-5; and a bidirectional AC/DC converter 3 for adjusting AC power from a system power supply 1 and DC power from the storage battery 5 and bidirectional charge/discharge devices 7-1 to 7-5. The bidirectional DC/DC converter 4, the bidirectional charge/discharge devices 7-1 to 7-5, and the bidirectional AC/DC converter 3 are organically controlled by a controller 8, and the amount of power supplied from the system power supply 1 is made uniform. When there is no system power supply, power is supplied from each storage battery to a load 20. |
