FIG. 6 is a diagram for explaining an example in which the power that the power sales applicant wants to sell is classified into the fourth attribute that is the sales price of the power. Specifically, FIG. 6A shows the first sales price C1 to the sixth sales price C6. FIG. 6 (B) shows the amount of power which has a first sales price C1 to a sixth sales price C6 and which the power sales applicant wants to sell.
In the example shown in FIG. 6, the first selling price C1 is cheaper than the second selling price C2, the second selling price C2 is cheaper than the third selling price C3, and the third selling price C3 is the fourth selling. It is cheaper than the price C4, the fourth selling price C4 is cheaper than the fifth selling price C5, and the fifth selling price C5 is cheaper than the sixth selling price C6.
The display unit 112 displays the amount of power which has the first sales price C1 and which the power sales applicant wants to sell in the first color indicating the first type. The display unit 112 displays the amount of power which has the second sales price C2 and which the power sales applicant wants to sell in the second color indicating the second type. The display unit 112 displays the amount of power which has the third sales price C3 and which the power sales applicant wants to sell in the third color indicating the third type.
In addition, the display unit 112 displays the amount of power which has the fourth sales price C4 and which the power sales desire person wants to sell in the fourth color indicating the fourth type. The display unit 112 displays the amount of power which has the fifth sales price C5 and which the power sales applicant wants to sell in the fifth color indicating the fifth type. The display unit 112 displays the amount of power which has the sixth sales price C6 and which the power sales applicant wants to sell in the sixth color indicating the sixth type.

  In the example illustrated in FIG. 6B, the area of the first color displayed by the display unit 112, the area of the second color, the area of the third color, the area of the fourth color, and the area of the fifth color The ratio between the area of the sixth color and the area of the sixth color has the first sales price C1 and the amount of power that the power sales applicant wants to sell, and the second sales price C2 and the power sales applicants sell The amount of power desired, the third sales price C3 and the amount of power the electric power sale requester wishes to sell, the fourth electric power sale price C4 and the power sale desired person And the amount of power that the prospective seller wants to sell, and the amount of the power that the prospective sales seller wishes to sell, and the fifth sales price C5. Equal to the ratio.

In the example shown in FIG. 1 and FIG. 6, since the display unit 112 is provided in the power trading intermediary system 1, whether the power purchase candidate is the target of the power trading whether or not the power of the type for which purchase is desired. Can be determined more easily than when the display unit is not provided. That is, the power transaction agent system 1 can improve the convenience of the power purchase candidate.
Specifically, in the example shown in FIG. 6, the display unit 112 has the first sales amount C1 and the first sales amount that the power sales candidate wants to sell, and the second sales price C2. And the amount of power of the second type that the electric power sales applicant wants to sell, the amount of electric power of the third type that the electric power sales desirer wants to sell, and the fourth type of electric power The amount of power of the fourth type which has the price C4 and which the power sales desirer wants to sell, and the amount of power of the fifth type which has the fifth sales price C5 and which the power sales desirer desires to sell The power purchase candidate can easily grasp the amount of power of the sixth type which has the sixth sales price C6 and which the power sales candidate wants to sell.

  As described above, in the example illustrated in FIG. 1, when the attribute of power that the power purchase candidate wants to purchase includes a plurality of types, the addition unit 115 of the power that the power purchase candidate wants to purchase Add priorities to multiple types.

FIG. 7 is a view for explaining an example of the priority added by the adding unit 115. As shown in FIG.
In the example shown in FIG. 7, electric power for 81 (= 9 × 9) units (blocks) is stored in the storage battery of the power sales applicant. Specifically, power of 11 units of the fourth type generated by the fourth power generation method (sunlight) P4 and power of 13 units of the second type generated by the second power generation method (thermal power) P2 Power of 8 units of the sixth type generated by the sixth power generation method (biomass) P6, power of 22 units of the first type generated by the first power generation method (hydraulic) P1, and third power generation The power of 27 units of the third type generated by the method (nuclear power) P3 is stored in the storage battery of the power sales applicant.
In the example shown in FIG. 7, the power purchase requester desires to purchase a total of 20 units (blocks) of power, and the desire is input to the processing unit 114. In addition, the priority of the type of power that the power purchase candidate wants to purchase is “sunlight → biomass → hydropower → thermal power → nuclear power”, and the addition unit 115 adds the priority and adds the priority to the processing unit 114. input.
As a result, the processing unit 114 causes the power purchase candidate to generate the fourth type of power of 11 units generated by the fourth power generation method (sunlight) P4, the sixth power generation method (biomass) P6 It is determined that it is desired to purchase six types of power for eight units and purchase of power for one unit of the first type generated by the first power generation method (hydraulic power) P1.
Therefore, the power trade mediation unit 11 can make the trade of power more smoothly than in the case where the addition unit is not provided.

In the example shown in FIG. 1, the third type of power (for example, the power generated by the third power generation method (nuclear power) P3) is included in the power that the power sales applicant wants to sell, and the third type If there are a plurality of power purchase applicants who wish to purchase power from the power source, the processing unit 114 sends the power purchase applicant having the highest priority to the third type among the plurality of power purchase applicants. , Assign a third type of power.
Therefore, the power trade mediation unit 11 can suppress the possibility that traffic of the third type of power will not be established.

FIG. 8 is a flowchart for explaining an example of processing by the processing unit 114.
In the example illustrated in FIG. 8, in step S1, the processing unit 114 determines that the fourth type of power (for example, the power generated by the fourth power generation method (sunlight) P4) corresponds to the power that the power sales applicant wants to sell. It is determined whether it is included. If the electric power sales applicant wants to sell includes electric power of the fourth type, the process proceeds to step S2. If the power sales applicant wants to sell does not include the fourth type of power, the routine shown in FIG. 8 is ended.
In step S2, the processing unit 114 determines whether or not there is a first power purchase candidate and a second power purchase candidate who desire to purchase the fourth type of power. If there is a first power purchase requester who wants to purchase the fourth type of power and a second power purchase requester, the process proceeds to step S3. If the first power purchase requester and the second power purchase requester who desire to purchase the fourth type of power do not exist, the routine shown in FIG. 8 is ended.

In step S3, the processing unit 114 adds the second power purchase candidate to the fourth type power and the priority assigned to the fourth power type by the first power purchase candidate. It is determined whether or not there is the same priority. When the priority given to the fourth type of power by the first power purchase applicant is equal to the priority given to the fourth power by the second power purchase candidate , And proceeds to step S4. When the priority given to the fourth type of power by the first power purchase applicant is not equal to the priority given to the fourth type of power by the second power purchase candidate Ends the routine shown in FIG.
In step S4, the processing unit 114 sets the amount of the fourth type of power that the first power purchase candidate wants to purchase equal to the amount of the fourth type of power that the second power purchase candidate wants to purchase. It is determined whether or not. If the amount of power of the fourth type that the first power purchase candidate wants to purchase is equal to the amount of power of the fourth type that the second power purchase candidate wants to purchase, the process proceeds to step S5. If the amount of power of the fourth type that the first power purchase candidate wants to purchase is not equal to the amount of power of the fourth type that the second power purchase candidate wants to purchase, as shown in FIG. End the routine

In step S5, the processing unit 114 controls the amount of power of the fourth type that the power sales candidate wants to sell, the amount of power of the fourth type that the first power purchase candidate wants to purchase, and the second power. It is determined whether the sum is smaller than the sum of the amount of power of the fourth type that the purchaser wants to purchase. The amount of power of the fourth type that the electric power sales applicant wants to sell is the amount of electric power of the fourth type that the first electric power purchase candidate wants to purchase, and the second amount of electric power that the second electric power purchase candidate wants to buy If the sum is smaller than the sum of the four types of power, the process proceeds to step S6. The amount of power of the fourth type that the electric power sales applicant wants to sell is the amount of electric power of the fourth type that the first electric power purchase candidate wants to purchase, and the second amount of electric power that the second electric power purchase candidate wants to buy If the sum is greater than the sum of the four types of power, the routine shown in FIG. 8 is ended.
In step S6, the processing unit 114 equally allocates the fourth type of power that the power sales candidate wants to sell to the first power purchase candidate and the second power purchase candidate.
Therefore, the power sales intermediary system 1 can suppress the possibility that sales of the fourth type of power will not be established.

FIG. 9 is a flowchart for explaining another example of processing by the processing unit 114.
In the example illustrated in FIG. 9, in step S11, the processing unit 114 includes the fifth type of power (for example, the power generated by the fifth power generation method (wind power) P5) in the power that the power sales applicant wants to sell. It is determined whether the If the power that the power sales desirer wants to sell includes the fifth type of power, the process proceeds to step S12. If the power sales applicant wants to sell does not include the fifth type of power, the routine shown in FIG. 9 is ended.
In step S12, the processing unit 114 determines whether there is a first power purchase candidate and a second power purchase candidate who desire to purchase the fifth type of power. If there is a first power purchase requester and a second power purchase requester who desires to purchase the fifth type of power, the process proceeds to step S13. If there is neither the first power purchase requester nor the second power purchase requester who desires to purchase the fifth type of power, the routine shown in FIG. 9 is ended.

In step S13, the processing unit 114 adds the second power purchase candidate to the fifth type power and the priority assigned to the fifth power type by the first power purchase candidate. It is determined whether or not there is the same priority. When the priority given to the fifth type of power by the first power purchase applicant is equal to the priority given to the fifth power by the second power purchase candidate , And proceeds to step S14. When the priority that the first power purchase requester adds to the fifth type of power is not equal to the priority that the second power purchase candidate adds to the fifth type of power Ends the routine shown in FIG.
In step S14, the processing unit 114 determines that the amount of power of the fifth type that the first power purchase candidate wants to purchase is greater than the amount of power of the fifth type that the second power purchase candidate desires to purchase It is determined whether or not. If the amount of power of the fifth type that the first power purchase candidate wants to purchase is larger than the amount of power of the fifth type that the second power purchase candidate wants to purchase, the process proceeds to step S15. If the amount of power of the fifth type that the first power purchase candidate wants to purchase is less than the amount of power of the fifth type that the second power purchase candidate wants to purchase, the routine shown in FIG. finish.

In step S15, the processing unit 114 determines that the amount of power of the fifth type that the power sales candidate wants to sell is the amount of power of the fifth type that the first power purchase candidate wants to purchase, and the second power. It is determined whether the sum is smaller than the sum of the amount of power of the fifth type that the purchaser wants to purchase. The amount of power of the fifth type that the power sales candidate wants to sell is the amount of power of the fifth type that the first power purchase candidate wants to purchase, and the second amount of power that the second power purchase candidate wants to purchase If the sum is smaller than the sum of the five types of power, the process proceeds to step S16. The amount of power of the fifth type that the power sales candidate wants to sell is the amount of power of the fifth type that the first power purchase candidate wants to purchase, and the second amount of power that the second power purchase candidate wants to purchase If the sum is greater than the amount of power of the five types, the routine shown in FIG. 9 ends.
In step S16, the processing unit 114 requests that the power seller want to sell so that the amount of power allocated to the first power purchase candidate is greater than the amount of power allocated to the second power purchase candidate. The power of the fifth type is allocated to the first power purchase candidate and the second power purchase candidate.
Therefore, the power sales intermediary system 1 can suppress the possibility that sales of the fifth type of power will not be established.

FIG. 10 is a flowchart for explaining another example of processing by the processing unit 114.
In the example illustrated in FIG. 10, in step S21, the processing unit 114 determines whether or not the power that the power purchase candidate wants to purchase includes a plurality of attributes. If the power purchase requester wants to purchase power includes multiple attributes, the process proceeds to step S22. If the power purchase requester does not include a plurality of attributes in the power purchase request, the routine shown in FIG. 10 is ended.
In step S22, the processing unit 114 determines that the power purchase candidate is the sixth type of power (for example, the sixth region (Kansai region) included in one of the plurality of attributes (for example, the first attribute shown in FIG. 2). 7) power of the seventh type (eg most expensive) desired to purchase the power generated by the AR 6 power plant and included in other attributes (eg, the fourth attribute shown in FIG. 6) of the plurality of attributes Whether or not it is desirable to purchase the If the power purchase candidate desires to purchase the sixth type of power included in one attribute and wants to purchase the seventh type of power included in the other attribute, the process proceeds to step S23. If the power purchase candidate does not want to purchase the sixth type of power included in one attribute, or if the power purchase candidate does not want to purchase the seventh type of power included in another attribute Ends the routine shown in FIG.

In step S23, the processing unit 114 determines whether the power purchase candidate has set the purchase power selection condition to AND. If the power purchase candidate has set the purchase power selection condition to AND, the process proceeds to step S24. If the power purchase applicant does not set the purchase power selection condition to AND, the routine shown in FIG. 10 is ended.
In step S24, the processing unit 114 sells power (for example, expensive power generated by a power plant in the sixth area AR6) where the power sales candidate is the sixth type power and the seventh type power. To determine if you want. If the power sales applicant desires to sell power of the sixth type and also of the seventh type, the process proceeds to step S25. If the power sales applicant does not want to sell the power of the sixth type and the seventh type, the routine shown in FIG. 10 is ended.
In step S25, the processing unit 114 allocates the power of the sixth type and also the seventh type of power to the power purchase candidate.

FIG. 11 is a diagram for explaining another example in which the power purchase candidate sets the purchase power selection condition to AND. In detail, FIG. 11A color-displays the power stored in the storage battery of the power sales applicant based on the second attribute (the attribute shown in FIG. 3). FIG. 11 (B) displays the electric power stored in the storage battery of the electric power sales applicant based on the fourth attribute (the attribute shown in FIG. 6) by color coding.
In the example shown in FIG. 11, electric power for 81 (= 9 × 9) units (blocks) is stored in the storage battery of the power sales applicant.
More specifically, in the example shown in FIG. 11A, power of 11 units of the fourth type generated by the fourth power generation method (sunlight) P4 and power generated by the second power generation method (thermal power) P2 The power of 13 units of the second type, the power of 8 units of the sixth type generated by the sixth power generation method (biomass) P6, and the first type of power of the first type generated by the first power generation method (hydropower) P1 The electric power for 22 units and the electric power for 27 units of the third type generated by the third electric power generation method (nuclear power) P3 are stored in the storage battery of the electric power sales applicant.

In the example shown in FIGS. 11A and 11B, the power of 11 units of the fourth type generated by the fourth power generation method (sunlight) P4 is expensive power. Of the 13 types of power of the second type generated by the second power generation method (thermal power) P2, 5 units of power is expensive power, and 8 units of power is inexpensive power.
Eight units of power of the sixth type generated by the sixth power generation method (biomass) P6 is inexpensive power. Of the 22 types of power of the first type generated by the first power generation method (hydraulic) P1, 6 units of power is expensive power, and 16 units of power is inexpensive power. Of the 27 types of power of the third type generated by the third power generation method (nuclear power) P3, 11 units of power is expensive power, and 16 units of power is inexpensive power.

In the example shown in FIG. 11, the power purchase candidate wants to purchase 20 units (blocks) of power in total. The power purchaser wants to buy cheap power and does not want to buy expensive power. In addition, the priority of the type of power that a power purchase candidate wants to purchase is "sunlight → biomass → hydropower → thermal power → nuclear power".
As a result, in the processing unit 114, the power purchase candidate is generated by the power of eight units of the sixth type generated by the sixth power generation method (biomass) P6, and by the first power generation method (hydropower) P1. It is determined that the purchase of power of 12 units of the first type is desired.

FIG. 12 is a flowchart for explaining another example of processing by the processing unit 114.
In the example illustrated in FIG. 12, in step S31, the processing unit 114 determines whether or not the power that the power purchase candidate wants to purchase includes a plurality of attributes. If the power that the power purchase candidate wants to purchase includes a plurality of attributes, the process proceeds to step S32. If the power purchase requester does not include a plurality of attributes in the power purchase request, the routine shown in FIG. 12 is ended.
In step S32, the processing unit 114 determines that the power purchase candidate is the eighth type of power (for example, the eighth region (Shikoku region) included in one of the plurality of attributes (for example, the first attribute shown in FIG. 2). The 9th type of power (for example, the most) which is desired to purchase the power generated by the AR8 power plant or which is included in another attribute of the plurality of attributes (for example, the fourth attribute shown in FIG. 6) Determine whether you want to purchase cheap power). If the power purchase candidate desires to purchase the eighth type of power included in one attribute, or purchases the ninth type of power included in another attribute, the process proceeds to step S33. . When the power purchase candidate does not want to purchase the eighth type of power included in one attribute, and the power purchase candidate does not also want to purchase the ninth type of power included in another attribute End the routine shown in FIG.

In step S33, the processing unit 114 determines whether the power purchase requester sets the purchase power selection condition to OR. If the power purchase candidate has set the purchase power selection condition to OR, the process proceeds to step S34. If the power purchase candidate has not set the purchase power selection condition to OR, the routine shown in FIG. 12 is ended.
In step S34, the processing unit 114 determines whether the power sales wish person wishes to sell the eighth type of power or the ninth type of power. If the power sales candidate wants to sell the eighth type of power or the ninth type of power, the process proceeds to step S35. If the power sales applicant does not want to sell the eighth type of power and does not want to sell the ninth type of power, the routine shown in FIG. 12 is ended.
In step S35, the processing unit 114 allocates the power of the eighth type or the power of the ninth type to the power purchase candidate.

  In the example illustrated in FIG. 1, when the processing unit 114 allocates the power that the power sales candidate wants to sell to the power purchase candidate, the billing unit 114A determines the amount and price of the power allocated to the power purchase candidate. And the charge amount for the power purchase applicant is calculated.

As described above, in the example illustrated in FIG. 1, the calculating unit 116 calculates the amount, the attribute, and the type of storage power that the power sales applicant wants to sell.
