== Overview ==
The dynamic pricing support system according to an embodiment of the present invention adjusts the power price for each time zone according to the power demand for each time zone, thereby performing dynamic pricing that realizes a shift in power demand, so-called peak shift. It is to support. In the present embodiment, the power price is not lowered, but the demand shift is promoted by changing the power price (change of the time zone in which the power is used), and the consumer is compensated by compensating the increase in the power price. Do not increase the burden of. In the present embodiment, the cost for peak shift (hereinafter referred to as adjustment cost) is calculated from the price increase amount and the compensation amount, and support for determining the power price increase amount or the demand amount reduction amount is determined. Do.

== Explanation of peak shift ==
FIG. 1 is a diagram for explaining a peak shift related to power demand. As shown in FIG. 1 (a), the power price (¥ / kWh) in the time zone t3 is cheaper than other time zones, so the power demand (kWh) in the time zone t3 as shown in FIG. 1 (b). ) Is increasing. If the power price at t3 is increased from p1 to p2 as shown by arrow 1 in FIG. 1 (c), the power price p3 at time t1 is cheaper than the power price p2 at t3, and demand Is encouraged to move demand to use power at t1. As shown in FIG. 1 (d), if the movement amount v1 of the demand amount at t3 has moved to t1, the power charge of the consumer is increased to the power demand amount v2 of t3 that has not moved for t3. The burden increases by the amount multiplied by the fraction d1 (= p2−p1), and the price difference d2 (= p3−) between the power price p1 of the t3 before the increase and the power price p3 of the t1 also for the demand destination t1. It is increased by the amount obtained by multiplying p1) by the movement amount v1. That is, the increase amount is calculated by the following equation (E1).

Increase in burden = d2 × v1 + d1 × v2 (E1)
Here, the peak shift is performed without substantially increasing the burden on the consumer by compensating for the increase in the electric power price. For this reason, the compensation amount is higher than the increased burden amount. However, even if the compensation is too high, the incentive for demand movement does not work. Therefore, in this embodiment, an amount obtained by multiplying the amount of demand before the increase in power price by dynamic pricing and the increase in power price is used as the compensation amount. That is, the compensation amount is calculated by the following equation (E2).

Compensation amount = d1 × (v1 + v2) (E2)
In the present embodiment, it is assumed that demand is moved rationally. That is, p3 <p2, and therefore, d2 <d1, thereby increasing the burden amount <compensation amount. This difference becomes the adjustment cost. The adjustment cost is expressed by the following equation E3.

Adjustment cost = compensation amount−burden increase amount = (d1−d2) × v1 (E3)
Therefore, there is no increase in the burden on the consumer, while the adjustment cost acts as an incentive for demand movement for the consumer.

  FIG. 12 is a diagram showing a flow of a price sensitivity creation process. The price sensitivity creation unit 214 performs the following processing for each consumer and each time zone.

  The price sensitivity creation unit 214 (corresponding to the price sensitivity acquisition unit of the present invention) reads out the power price of the time zone from the power price storage unit 231 as the original price (S501), and the demand of the time zone. The amount is read from the demand plan storage unit 232 and used as the original demand amount (S502), and a predetermined step value is set for the price increase Δp (S503). The price sensitivity creation unit 214 reads out the power price for each time zone from the power price storage unit 231 to make a price set (S504), and adds Δp to the power price in the time zone of the price set (S505). The price sensitivity creation unit 214 performs the following processing while the power price in the time zone of the price set is equal to or less than a predetermined maximum amount.

  The price sensitivity creation unit 214 transmits a demand plan prototype request including a price set to each demand planning device 10 (S506), and receives the demand plan transmitted from each demand planning device 10 in response to the demand plan prototype request. Then, the average value of the difference between the demand amount in the received time plan and the original demand amount in the received demand plan is calculated and set as the reduction amount corresponding to the consumer, the time zone, and Δp (S508). ). The price sensitivity creation unit 214 adds the step value to Δp (S509), and also adds the step value to the power price in the time zone in the price set (S510).

  The adjustment cost calculation unit 217 sums the demand amounts stored in the demand plan storage unit 232 for each time zone to obtain an original total demand plan (S521). The total amount of demand for each time zone included in the original gross demand plan is called the original demand. The adjustment cost calculation unit 217 reads the power price for each time zone from the power price storage unit 231 to make a price set (S522), and adds the target increase to the power price of the price set corresponding to the reduction time zone (S523). .

  The adjustment cost calculation unit 217 transmits a demand plan prototype request including a price set to each demand planning device 10 (S524), and receives a demand plan from each demand planning device 10 (S525). The adjustment cost calculation unit 217 totals the demand amounts for each time zone for the demand plan received from each demand planning device 10 to obtain a new total demand plan (S526). The total amount of demand for each time zone included in the new total demand plan is called new demand. The adjustment cost calculation unit 217 calculates v2 by subtracting the new demand amount in the reduction time zone from the original demand amount in the reduction time zone (S527), and multiplies the target increase by v2 to obtain a burden increase amount (S528).

  The adjustment cost calculation unit 217 reads the power price in the time zone and the power price in the reduction time zone from the power price storage unit 231 for each time zone in which the new demand is larger than the original demand (S529). The read power price difference is set to d2 (S530). The adjustment cost calculation unit 217 sets the difference between the new demand amount and the original demand amount as v1 (S531), and adds an amount obtained by multiplying d2 by v1 to the burden increase amount (S532).

  The adjustment cost calculation unit 217 calculates the adjustment cost by subtracting the increased amount of burden calculated as described above from the compensation amount calculated by the compensation amount calculation unit 216 (S533).

== Screen example ==
FIG. 14 is a diagram illustrating an example of a screen displayed on the support device 20. The screen 61 displays a graph 611 in which the demand amounts stored in the demand plan storage unit 232 are tabulated for each time zone. About the demand amount of the time slot | zone exceeding the predetermined maximum value, you may change and display a color, a width | variety, etc. The screen 61 includes a pull-down list 612 for selecting a reduction time zone, and a text box 613 for inputting a target reduction amount. When a time zone is selected in the pull-down list 612, a target reduction amount is input in the text box 613, and the button 614 is pressed, the reduction value input unit 215 stores the amount of demand reduction from the price sensitivity storage unit 233. The smallest amount of price increases larger than the target reduction amount is acquired as the target increase amount, and the compensation amount calculation unit 216 calculates the compensation amount by the above-described equation E2. In addition, the adjustment cost calculation unit 217 calculates the adjustment cost by the process of FIG. 13 described above. Then, the target reduction amount 621 input to the text box 613, the target increase 622 acquired by the reduction value input unit 215, the compensation amount 623 calculated by the compensation amount calculation unit 216, and the adjustment cost calculation unit 217 calculated A screen 62 including the adjustment cost 624 is displayed.

== Example of effects ==
As described above, according to the dynamic pricing support system of the present embodiment, the compensation amount is obtained by multiplying the original demand (v1 + v2) in the reduction time zone (t3 in FIG. 1) by the target increase (d1). Therefore, by paying this compensation amount to the consumer, the burden on the consumer is avoided, while the power price (p2) in the reduced time zone after the increase is less expensive ( If t1) exists, an incentive to move demand to t1 can be activated.

  Further, when the revenue source corresponding to the drop in the revenue price (d1-d2) due to the demand shift from t3 to t1 becomes the adjustment cost, the adjustment cost is output as shown in the screen 62 in FIG. Therefore, the price setter can determine whether or not to adjust the price while comparing the adjustment cost by setting the power price related to dynamic pricing with the power generation cost.

  In the present embodiment, since the target increase amount is determined from the target reduction amount using the price sensitivity, it is possible to easily determine a reasonable price in dynamic pricing. In addition, since the price increment can be determined according to the price sensitivity of the consumer, it is possible to make a reasonable price adjustment.

  In the present embodiment, the price sensitivity can be investigated while making an inquiry to the demand planning device 10. Therefore, accurate price sensitivity can be obtained. Further, since the target increase amount can be obtained from the target reduction amount according to the accurate price sensitivity, it is possible to rationally determine the increase amount of the power price in the dynamic pricing.
