Power supply system, power supply control device, power supply control method and program in the power supply system

Japanese Patent JP6310728

B2

PROBLEM TO BE SOLVED: To improve reliability in supplying power to a load apparatus, in a power supply system comprising a power supply apparatus for compensating for power to be supplied to the load apparatus.SOLUTION: A DC power supply system 1 supplies power from a DC power supply apparatus 3 to load apparatuses through power supply paths (dendritic power supply path 12 and loop system power supply path 13) as well as supplies power from power supply apparatuses (photovoltaic power generation apparatus 4 and power storage apparatus 7) for compensating for power to be supplied to the load apparatuses to the load apparatuses through the power supply paths. A switch unit is disposed, on a power supply path, at a position dividing a range to which the DC power supply apparatus 3 supplies power with a range to which the DC power supply apparatus 3 does not supply power. A power supply control apparatus 6 controls a power supply range on the power supply path by transmitting a switch control signal CNT to the switch unit to control an open/close state of the switch unit by using the switch control signal CNT.
