1. A power supply-demand adjustment device that performs output distribution by distributing at least a part of procured adjustment power to an adjustment power supply in a power system, the power supply-demand adjustment device comprising:
a processor and a memory storing instructions that, when executed by the processor, cause the processor to:
determine a supply-demand imbalance of the power system including N adjustment power supplies (N is a natural number of 2 or more); and
perform output distribution to M adjustment power supplies (M is a natural number of N or less) among the N adjustment power supplies in accordance with an advantage order of adjustment cost, based on adjustment management information and the determined supply-demand imbalance for each of the N adjustment power supplies, the adjustment management information including an output change rate, a distributed output, and an output limit value,
wherein the output distribution in accordance with the advantage order for each period comprises:
(x) distributing an output to each of the M adjustment power supplies in an increasing direction in ascending order of the adjustment cost, or distributing the output to each of the M adjustment power supplies in a decreasing direction in descending order of the adjustment cost; and
(y) determining a distribution control function for each of the adjustment power supplies in which a first axis represents the distributed output and a second axis represents a distribution target output, wherein the distribution target output is an output distributed in the period, the function being configured such that, regardless of whether the output direction is the increasing direction or the decreasing direction, the distribution target output is reduced in response to a reduction in a difference between the distributed output and the output limit value of the adjustment power supply.
