FIG. 16 is a flowchart for explaining compensation fee calculation processing S1600.

  As shown in the figure, the compensation fee calculation unit 68 first receives a compensation type (voltage fluctuation compensation, harmonic expansion compensation, voltage flicker compensation, voltage imbalance) from the user via the input device 14 as a subject of fee calculation. Compensation designation is accepted (S1611). Next, the compensation fee calculation unit 68 accepts designation of a period (monthly, yearly, arbitrary period) for which the fee is to be calculated from the user via the input device 14 (S1612). Next, the compensation fee calculation unit 68 acquires the compensation amount upper limit value of the compensation type received in S1611 from the compensation amount upper limit storage unit 65 (S1613).

  Subsequently, the compensation fee calculation unit 68 selects one day during the period accepted in S1612 (S1614), and acquires the compensation amount for the day selected in S1614 of the compensation type accepted in S1611 from the compensation amount storage unit 64. (S1615).

  Next, the compensation fee calculation unit 68 determines whether the day selected in S1614 is a weekday or a holiday based on the calendar information stored in the calendar information storage unit 67 (S1616). If the selected day is a weekday (S1616: weekday), the compensation fee calculation unit 68 obtains the compensation fee by acquiring the weekday unit price table from the unit price table storage unit 66 (S1617). If the selected day is a holiday (including holidays) (S1616: holiday), the compensation fee calculation unit 68 obtains a holiday unit price table from the unit price table storage unit 66 and obtains a compensation fee (S1618).

FIG. 17 shows an example of calculating the compensation fee when the selected day is a weekday, and FIG. 18 shows an example of calculating the compensation fee when the selected day is a holiday. As shown in these figures, the daily compensation fee is the sum of the product of the compensation amount for each hour acquired in S1615 and the compensation fee unit price corresponding to each time acquired from the unit price table for one day. Desired. For example, in the example of FIG. 17, the compensation fee for one day is obtained from the following equation.
Compensation fee for weekdays = q1 x C5 + q2 x C3 + q3 x C2 + q4 x C5 (Formula 1)

In the case of the example of FIG. 18, the compensation fee for one day is obtained from the following equation.
Compensation charge for one day of holiday = q5 x C8 + q6 x C9 + q7 x C8 (Formula 2)

  The compensation fee calculation unit 68 applies a compensation fee corresponding to the portion where the compensation amount exceeds the compensation amount upper limit value of each voltage adjusting device 8 managed by the compensation amount upper limit storage unit 65. Is not added.

  Returning to FIG. 16, the compensation fee calculation unit 68 stores the compensation fee obtained in S1617 or S1618 (S1619).

  Subsequently, the compensation fee calculation unit 68 determines whether there is an unselected day in the period accepted in S1612 (S1620). If there is an unselected day (S1620: YES), the compensation fee calculation unit 68 selects an unselected day in the period accepted in S1612 (S1631), and repeats the processing from S1615 for the selected day. On the other hand, if all the days in the period received in S1612 have been selected (S1620: NO), the process proceeds to S1621.

  In S1621, the compensation fee calculation unit 68 calculates the compensation fee during the target period designated in S1612 by totaling the compensation fees stored in S1619. Then, the compensation fee calculation unit 68 outputs the calculated compensation fee to the output device 15 (S1622).

  As described above, according to the billing method of the present embodiment, the consumer 6 efficiently calculates the compensation fee for compensating for the voltage trouble applied to the transmission and distribution line 5 by using the electric power, Appropriate billing can be done at home.

  Further, according to the charging method of the present embodiment, the compensation fee is individually charged according to the compensation type such as the effective voltage value, voltage fluctuation, distortion rate, voltage flicker, and voltage imbalance rate. It is possible to charge a detailed compensation fee according to the mode.

  Further, according to the billing method of the present embodiment, the information processing apparatus 10 obtains the compensation fee by distinguishing between weekdays and holidays, so that the compensation fee can be appropriately charged according to the actual usage of the customer 6.

  Further, since the information processing apparatus 10 does not charge the compensation fee for the amount exceeding the upper limit of the compensation amount, the information processing device 10 can be prevented from being charged even for the uncompensated amount.

  The embodiment described above is for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes the equivalents thereof.
