Energy region division device and method

The invention discloses an energy region division device and method. The method comprises the following steps: identifying all energy consumption buildings in an area; obtaining load curves for representing consumption levels for at least one kind of energy of each energy consumption building in all energy consumption buildings within a preset time period; determining one or more groups of target load curves in the load curves of each energy consumption building, wherein each group of target load curve is corresponding to one kind of energy, and characteristic parameters of superposed curves of one group of target load curves corresponding to some kind of energy meet a preset value, or any two load curves in one group of target load curves have time sections, the variation tendencies of which are opposite; and determining the region, where one group of energy consumption buildings corresponding to one group of target load curves locate, as one energy region, wherein the energy region is corresponding to at le
