1. A power adjustment method in a microgrid connected to an external power supply system and having a power storage unit capable of adjusting an amount of stored power by charging and discharging and a power consumption unit capable of adjusting power consumption of the power, the method comprising:
adjusting transmission and reception of the power by simultaneously controlling the power consumption in the power consumption unit and charge/discharge power in the power storage unit in order to transmit and receive power based on a planned value determined for each planned section to and from the external power supply system,
wherein, in the adjustment, a target value of the power consumption in the power consumption unit is determined at a period of the planned section or a period shorter than the planned section, and the charge/discharge power in the power storage unit is controlled so that a difference between a target trajectory, which is a fluctuation curve of an integrated value of the power transmitted and received to and from the external power supply system in the planned section for realizing the planned value, and an integrated actual value of the power transmitted and received to and from the external power supply system is reduced.
