PROBLEM TO BE SOLVED: To easily change discharge priority of power supply equipment without requiring electric work.SOLUTION: A distributed power supply system comprises: first power supply equipment for supplying power to a load through a first connection point; second power supply equipment for supplying power to the load through a second connection point; a first current sensor for detecting current flowing in a first power supply cable; and a second current sensor for detecting current flowing in the first power supply cable. The first power supply equipment controls power to be output to the first connection point so that a value of current detected by the first current sensor becomes close to a first threshold, the second power supply equipment controls power to be output to the second connection point so that a value of current detected by the second current sensor becomes close to a second threshold differing from the first threshold. When the second power supply equipment supplies power to the load preferentially to the first power supply equipment, the second threshold is set to be a value smaller than the first threshold, when the first power supply equipment supplies power to the load preferentially to the second power supply equipment, the first threshold is set to be a value smaller than the second threshold.SELECTED DRAWING: Figure 1 |
