Summary:PROBLEM TO BE SOLVED: To control a power storage device with a temporal margin, so as to prevent stoppage of a solar power generation system, when the solar power generation system charges the power storage device by using the autonomous operation output.SOLUTION: A power controller 300 for controlling a power storage device 200 by means of a power conditioner 100 for converting DC power into AC power includes an acquisition unit 301 for acquiring the value of an intermediate link voltage, i.e., the voltage between a DC/DC converter 101 and a DC/AC converter 102 included in the power conditioner 100, and a control unit 302 for controlling the charging power that is drawn by the power storage device 200 from the power conditioner 100.SELECTED DRAWING: Figure 1 【課題】太陽光発電システムが自立運転出力を用いて蓄電装置を充電する際に、過負荷による太陽光発電システムの停止を防ぐように、時間的なマージンを持って蓄電装置を制御する。【解決手段】本発明に係る電力制御装置３００は、直流電力を交流電力に変換するパワーコンディショナ１００によって充電される蓄電装置２００を制御する電力制御装置３００であって、パワーコンディショナ１００が備えるＤＣ／ＤＣコンバータ１０１とＤＣ／ＡＣコンバータ１０２の間の電圧である中間リンク電圧の値を取得する取得部３０１と、中間リンク電圧の値に応じて、蓄電装置２００がパワーコンディショナ１００から引き込む充電電力を制御する制御部３０２とを備える。【選択図】図１
