PROBLEM TO BE SOLVED: To make it easier to control electric energy that an electric power supply company estimates for a power storage device.SOLUTION: A charge/discharge instruction device comprises: an acquisition part which acquires charging state information showing a charging state of power storage devices for each electric power system in which a plurality of power storage devices which charge/discharge electric power are connected based on charge/discharge instruction; a demand forecast calculation part which calculates demand forecast information for each system based on temporal changes of the charging state information of a power storage device connected to an electric power system out of electric power systems; a chargeable/dischargeable electric energy calculation part which calculates chargeable/dischargeable electric energy for each electric power system as chargeable/dischargeable electric energy for each system based on acceptance/rejection information showing, in the case where a charge/discharge instruction is output, whether or not the power storage device accepts charge/discharge of electric power based on the charge/discharge instruction and the charging state information; a charge/discharge instruction generation part which generates a charge/discharge instruction showing a charging/discharging amount of each power storage device based on demand forecast information for each system and chargeable/dischargeable electric energy for each system; and a charge/discharge instruction output part which outputs the charge/discharge instruction to the power storage device.SELECTED DRAWING: Figure 1

    【課題】蓄電装置に対して電力供給事業者が想定した電力量の制御を行いやすくする。【解決手段】充放電指示に基づいて電力を充放電する蓄電装置が複数接続される電力系統毎に、蓄電装置の充電の状態を示す充電状態情報を取得する取得部と、電力系統のうちのある電力系統に接続される蓄電装置の充電状態情報の時間変化に基づいて、系統毎需要予測情報を算出する需要予測算出部と、充放電指示が出力された場合に当該充放電指示に基づく電力の充放電を当該蓄電装置が受け入れるか否かを示す諾否情報と、充電状態情報とに基づいて、電力系統毎の充放電可能な電力量を系統毎充放電可能電力量として算出する充放電可能電力量算出部と、系統毎需要予測情報と、系統毎充放電可能電力量とに基づいて、それぞれの蓄電装置の充放電量を示す充放電指示を生成する充放電指示生成部と、充放電指示を蓄電装置に出力する充放電指示出力部とを備える充放電指示装置。【選択図】図1
