Summary:To provide a centralized management device capable of flexibly adjusting various performances when calculating an index for controlling to-be-adjusted power to target power.SOLUTION: A central management device MC1 is used for managing a power control device for controlling output power on the basis of an optimization problem using a control index for controlling to-be-adjusted power to target power. The centralized management device MC1 includes: a target power setting unit 11 for setting the target power; adjustment target power detection means (interconnection point power detection unit 12) for detecting the adjustment target power; an index calculation unit 13 for calculating the control index based on the power to be adjusted and the target power; and a transmission unit 14 for transmitting the control index to the power control device. The index calculation unit 13 uses a deviation between the adjustment target power and the target power as an input signal and calculates the control index based on a state equation obtained by converting a first transfer function with the control index as an output signal from a transfer function representation to a state space representation. The first transfer function includes a second transfer function other than a constant and an integral element.SELECTED DRAWING: Figure 2 【課題】調整対象電力を目標電力に制御するための指標の算出時における各種性能を柔軟に調整可能な集中管理装置を提供する。【解決手段】本開示の集中管理装置ＭＣ１は、調整対象電力を目標電力に制御するための制御指標を用いた最適化問題に基づいて出力電力を制御する電力制御装置を管理する集中管理装置ＭＣ１であって、目標電力を設定する目標電力設定部１１と、調整対象電力を検出する調整対象電力検出手段（連系点電力検出部１２）と、調整対象電力と目標電力とに基づいて制御指標を算出する指標算出部１３と、制御指標を電力制御装置に送信する送信部１４と、を備えており、指標算出部１３は、調整対象電力と目標電力との偏差を入力信号とし、制御指標を出力信号とする第１伝達関数を、伝達関数表現から状態空間表現に変換した状態方程式に基づいて、制御指標を算出し、第１伝達関数は、定数以外の第２伝達関数と積分要素とを含んでいる。【選択図】図２
