A load estimating method of a power system and a device thereof are disclosed. According to an aspect of the present invention, the load estimating method of the power system comprises the following steps of: selecting, by a representative value selecting unit, a predetermined number of representative load values from time unit loads of a certain period in the past interval for each distribution line; generating, by a load function generating unit, a daily load function and coefficient for each distribution line by using the predetermined number of representative load values for each distribution line; and storing, by the load function generating unit, at least one of index information, characteristic information, and interpolation method information for each distribution line in association with a corresponding coefficient in a database.
