3. The system further includes a command unit that outputs control commands for controlling the charging and discharging of the aforementioned storage battery, The apparatus according to claim 1, wherein the amount of power supplied indicated by the adjustment power-related information includes a value calculated using the discharge power indicated by the control command during a certain time period, a reference value of the charging power during a certain time period, the charging efficiency of the battery, and the discharge efficiency of the battery.

4. The apparatus according to claim 1, wherein the amount of power supplied indicated by the adjustment power-related information includes at least a value calculated using the amount of power of charging and discharging of the storage battery measured during a certain time period and a reference value of the charging power during that time period.

5. The apparatus according to claim 1, wherein the amount of power supplied indicated by the adjustment power-related information includes a value calculated using the power of charging and discharging the battery measured during a certain time period, a reference value of the charging power during a certain time period, the charging efficiency of the battery, and the discharging efficiency of the battery.

6. The apparatus according to claim 1, wherein the amount of power supplied indicated by the adjustment power-related information includes at least the integrated value obtained by accumulating the discharge power of the storage battery, calculated using the frequency deviation, over a certain time period.

7. The apparatus according to claim 1, wherein the amount of power supplied indicated by the adjustment power-related information includes a value calculated using at least the discharge power of the battery calculated using the frequency deviation, a reference value of the charging power for a certain time period, the charging efficiency of the battery, and the discharge efficiency of the battery.

8. The apparatus according to any one of claims 1 to 7, further comprising a power supply calculation means for calculating the power supply of the storage battery during a predetermined time period such that the power supply available for each of the multiple time periods constituting the transaction period is substantially the same.

9. The aforementioned power supply calculation means is: The apparatus according to claim 8, which calculates the power that can be supplied from the storage battery during a predetermined time period by performing a calculation using the upper limit capacity information of the storage battery, the length of the time period, and information indicating the length of time from the start of a certain time period to the start of a predetermined time period.

10. The aforementioned power supply calculation means is: The apparatus according to claim 8, which calculates the power that can be supplied from the battery during a predetermined time period by performing a calculation using the upper limit capacity information of the battery, the length of the time period, the discharge efficiency of the battery, and information indicating the length of time from the start of a certain time period to the start of a predetermined time period.

11. The apparatus according to claim 8, wherein the power supply calculation means further sets the power indicated by the upper limit output information of the storage battery to the available power supply if the calculated power exceeds the power indicated by the upper limit output information of the storage battery.

12. A method implemented by the processor, The steps include: obtaining adjustment capacity-related information indicating the amount of electricity supplied from a storage battery during a certain time period to which a predetermined time period belongs, at a time prior to the start of that predetermined time period among several time periods that can constitute a trading period in the electricity trading market; A method comprising the step of calculating a reference value for the charging power of the storage battery during a predetermined time period, based on the amount of power supplied indicated by the adjustment power-related information for a certain time period and time information indicating the length of the predetermined time period.

13. A program for causing a processor to perform the method described in claim 12.
