POWER DEMAND AND SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a power demand and supply system defining how to divide surplus power and deficient power to charge and discharge each of a vehicle side storage battery and facility side storage battery.

SOLUTION: A facility 20 has: the facility side storage battery 31b as a power supply section P in which one or more target facility charging rate levels are set; an optimum planning section 21c for generating an optimum operation plan of the power supply section P for supplying power to a power load device 30 and calculating a planned total charging amount or a planned total discharging amount to at least one of the facility side storage battery 31b and the vehicle side storage battery 14b; and a priority order deciding section 21d. The vehicle side storage battery 14b is provided as a configuration working as the power supply section P capable of setting one or more target vehicle charging rate levels. The priority order deciding section 21d decides a charging priority order and a discharging priority order for a plurality of levels obtained by combining the target facility charging rate level and the target vehicle charging rate level, based on the setting conditions.
