Abstract: A power reception control method for a power storage element controls element-receiving electric power received by the power storage element in an electric power system for supplying electric energy to a load group including plural power storage elements. The power reception control method acquires differential electric power by subtracting a current value of total transmitted electric power from a maximum value of the total transmitted electric power that is an available amount to be supplied to the entire load group via an electric power supply base point, calculates a degree of priority of the power storage element in accordance with a numerical value indicating a demand of a user, multiplies the differential electric power by the degree of priority to calculate element differential electric power, and adds the element differential electric power to the previous element-receiving electric power so as to update the element-receiving electric power.

Abstract: The power reception control device is configured to: acquire information indicating differential power obtained by subtracting a current value of total transmission power transmitted to an entirety of a load group via a power supply base point, from a maximum value of the total transmission power transmittable to the entirety of the load group via the power supply base point; calculate element differential power of an own power receiving element by multiplying the differential power indicated by the acquired information by a priority of the own power receiving element, the priority indicating a degree to which power reception of the own power receiving element takes priority over power reception of another power receiving element; and control charging-discharging of the own power receiving element based on the element differential power and a charge-discharge schedule of a power system.

Abstract: A charge/discharge control method for a charge/discharge element includes receiving a request value (Pfr) of a frequency adjustment capacity according to a system frequency (f) of an electric power system (10) based on a priority degree (β) and the request value (Pfr) being received, the priority degree indicating a degree at which charging or discharging of an own element (EV1) is prioritized over charging or discharging of another charge/discharge element (EV2, EV3, . . . ), correcting the output property to increase an upper limit value or a lower limit value of an output range as the priority degree (β) is higher, and performing charging or discharging with an output determined based on a deviation (Δf) between the system frequency (f) measured at a connection end to the electric power system (10) and a reference frequency (fref) of the electric power system (10) and the output property after the correction.
