1. A resource distribution method in a smart grid system that includes a plurality of devices in a plurality of stages, comprising steps for:

  • calculating available resources for each device based on a budget and price data at each stage;

    calculating reference resources for each device based on historical data including resource consumption at previous stages;

    determining reserved resources for each device based on the available resources and the reference resources for each device;

    comparing the determined reserved resources with required resources for each device; and

    classifying the devices based on results of the comparison wherein each device is classified into an S-device with surplus resources if the determined reserved resources are more than the required resources for said each device, and into a D-device with deficiency resources when the determined reserved resources are less than the required resources for said each device, the D-device being one of a non-shiftable device, a controllable device and a shiftable device; and

    calculating a resource bargaining unit (RBU) if a total amount of the surplus resources satisfies all non-shiftable D-devices and satisfies minimum requirements of all controllable D-devices, whereinthe RBU is iteratively distributed to all D-devices, anda size of the RBU at a k-th iteration of each stage is determined as being the smaller one between a minimum value of a gap that is between the required resources and currently allocated resources for each device, and a value of the total surplus resources at the k-th iteration divided by a number of D-devices of which the required resources are not satisfied, k being a positive integer.
