To provide a device and a method for conditioning power supply and demand that achieves both reduction in costs and maintenance of the speed of output change while suppressing frequency fluctuations caused by supply-demand imbalance.SOLUTION: A device 10 for conditioning power supply and demand is for performing output allocation of allocating at least a portion of procured conditioning power to conditioning power supply devices in a power system. The device 10 includes an imbalance identifying unit 161 for identifying a supply-demand imbalance of a power system having N conditioning power supply devices and an output allocation unit 152 for performing output allocation according to a merit order of conditioning costs on M units of conditioning power supplies with respect to the M units of conditioning power supplies out of N units of conditioning power supplies on the basis of identified supply-demand imbalance and conditioning management information, which is information representing the output change rate, allocated output, and output limit values for each of the N units of the conditioning power supplies.SELECTED DRAWING: Figure 3 【課題】需給インバランスによる周波数変動を抑制しつつ、調整コストの低減と出力変化速度の維持とを両立する電力需給調整装置及び方法を提供する。【解決手段】調達された調整力の少なくとも一部を電力系統における調整電源に配分する出力配分を行う電力需給調整装置１０であって、Ｎ台の調整電源を有する電力系統の需給インバランスを特定するインバランス特定部１６１と、Ｎ台の調整電源の各々について出力変化速度、配分済み出力及び出力限界値を表す情報である調整管理情報と、特定された需給インバランスとを基に、Ｎ台の調整電源のうちのＭ台の調整電源に対してＭ台の調整電源の調整コストのメリットオーダーに応じた出力配分を行う出力配分部１５２と、を備える。【選択図】図３
