摘要： 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.

摘要： A power reception control method for a power reception element controls element-receiving electric power received by the power reception element in an electric power system for supplying electric energy to a load group including plural power reception elements via an electric power supply base point. 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 the electric power supply base point, multiplies the differential electric power by a degree of priority of the power reception element to calculate element differential electric power, adds the element differential electric power to the previous element-receiving electric power, and subtracts an electric power correction value based on the element-receiving electric power so as to update the element-receiving electric power.

摘要： A charge-discharge control system according to an aspect of the present invention is a charge-discharge control system in which each of a plurality of charge-discharge elements autonomously controls charging-discharging, and the charge-discharge control system includes: an external control device that broadcasts a control signal to the charge-discharge elements that perform charging-discharging; and an authentication device that permits charging-discharging of each of the charge-discharge elements. The charge-discharge elements having received the control signal transmit, to the authentication device, a permission request signal for requesting permission for charging-discharging, which is based on the received control signal. The authentication device having received the permission request signal determines whether the permission request signal is a permission request signal based on the control signal received by the charge-discharge elements, and the authentication device connects a power line for performing charging-discharging to the charge-discharge elements if the authentication device determines that the permission request signal is the permission request signal based on the control signal received by the charge-discharge elements.

摘要： 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.

摘要： A charge-discharge loss reduction device includes a power reception control device that controls power received or discharged by power receiving elements included in a load group, in a power system that supplies electric energy to the load group including the power receiving elements via a power supply base point. The power reception control device is configured to change a priority of an own power receiving element using a charge-discharge state 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.

摘要： 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.
