In response to the reception of the power purchase / purchase request, the facility-specific control unit 107 transmits the power purchase power amount and the power sale power amount during the period from the present to the past one minute to the power related information presentation device 200.
In addition, if only the power purchase is performed in the customer facility 10 from the present to the past one minute, only the purchased power amount is transmitted as a response to the request for the purchased or sold power amount. Moreover, if only the power sale is performed in the customer facility 10 from the present to the past one minute, only the power sale power amount is transmitted as a response to the request for the power sale amount.
Furthermore, if a period of purchasing power and a period of selling power are included in the customer facility 10 from the present to the past one minute, as a response to the request for buying and selling power, the purchased power amount and the sold power Competence is transmitted.
The power amount acquisition unit 202 acquires the purchased power amount and the sold power amount transmitted from each facility-specific control unit 107 as described above as the purchased power amount and the sold power amount of each consumer.

Step S103: Subsequently, the intra-area trading power amount calculation unit 203 calculates an in-area purchased power amount TB that is the total of the purchased power amount for each consumer acquired in step S102.
The intra-area trading power amount calculation unit 203 can obtain the in-area purchased power amount TB according to the following formula 1, where Pb _i is the purchased power amount of the i-th consumer in the 1st to n-th consumers.

Step S104: The intra-area trading power amount calculation unit 203 calculates an in-area power sales amount TS that is the total of the power sales amount for each consumer acquired in step S102.
The intra-area trading power amount calculation unit 203 can obtain the in-area power selling power amount TS by the following formula 2 with Ps _i being the purchased power amount of the i-th consumer in the 1st to n-th consumers.

  Step S105: Next, the coefficient calculation unit 204 derives an in-area effective interchangeable power amount Pv. The in-area effective accommodation power amount Pv is the amount of power that is effectively accommodated in the area at the present time. The in-area effective interchangeable power amount Pv is obtained by selecting a smaller value from the in-area purchased power amount TB calculated in step S103 and the in-area sold power amount TS calculated in step S104. It is done. That is, the in-area effective interchangeable power amount Pv is obtained by the following Equation 3.

FIG. 5 shows an example of the in-area purchased power amount TB, the in-area sold power amount TS, and the in-area effective interchangeable power amount Pv on a certain day (from 0:00 to 23:00). In addition, the figure has shown the example in the case where it is made to output the electric power generated by the solar cell 101 as electric power sales power in each of the customer facilities 10. FIG. In this case, the electric power stored in the storage battery 103 is used in the customer facility 10 and is controlled so as not to be output to the in-area electric power system 3 as electric power sold.
The solar cell 101 performs power generation according to the intensity of sunlight during the day, and does not generate power at night when sunlight is not obtained. For this reason, surplus power can be generated in the solar cell 101 during the daytime. In the figure, the amount of electric power sold in the area TS corresponding to the surplus power increases from around 7:30, reaches a maximum from around 12:00 to around 13:00, and then gradually decreases until about 18:00. A state of “0 kwh” is shown.
On the other hand, since the power of the solar cell 101 cannot be used at night when the solar cell 101 cannot generate power, the purchased power from the commercial power source increases. For this reason, in the time zone from 0 o'clock to about 8 o'clock and from about 18 o'clock to 24 o'clock, the in-area purchased electric energy TB increases. Here, a further increase in the amount of electricity purchased in the area TB from around 3 o'clock to around 6 o'clock is to supply power to a load such as an electric water heater or charge the storage battery 103 using late-night power with a low electricity bill. It depends on. And in the daytime, since the electric power output from the solar cell 101 can be used, the in-area purchased electric energy TB decreases.
In the same figure, the state where the in-area electric power sales amount TS is larger than the in-area electric power purchase amount TB indicates that a part or all of the electric power required as the in-area electric power purchase amount TB in the electric power management area 1 is It can be said that a part of the in-area electric power sales amount TS corresponding to the surplus of electric power generated by the solar cell 101 is accommodated as the in-area effective interchangeable electric energy amount Pv. At this time, the in-area effective interchangeable power amount Pv tends to increase.
On the other hand, the state where the in-area purchased electric energy TB is larger than the in-area electric power sold TS is that, in the electric power management area 1, the electric power purchase consumer uses all the in-area electric power sold TS, and then the electric power management area 1 It can be said that it is in a state of being supplied with insufficient power from outside. At this time, the in-area effective interchangeable power amount Pv tends to be small.

Returning to FIG.
Step S106: Then, the coefficient calculation unit 204 calculates a first coefficient K ₁ to be used when calculating the power purchase consumer Distribution Amount alpha _b. The first coefficient K ₁ can be calculated by the following equation 4.
K ₁ = Pv / TB (Expression 4)
Equation 4 in terms of the principle was to determine the first coefficient K ₁ by dividing the DENDEN competence TS sales area in area purchased electric power amount TB, Denden competence TS is area purchased electric power amount sale area When larger than TB, the first coefficient K ₁ is “1”.
The first coefficient K ₁ is supplied from the generated power or the storage battery of the solar cell 101 of the power selling customer in the power management area 1 out of the total amount of purchased power purchased by the power buying customer in the power management area 1. The ratio of the amount of power covered by the generated power is shown.
Therefore, the first coefficient K ₁ is an in-area energy self-sustained rate ε that indicates how much of the power required in the power management area 1 is covered by the power output in the power management area 1. Represents. That is, the first coefficient K ₁ = in-area energy self-sustained rate ε.

Step S107: The coefficient calculation unit 204 calculates a second coefficient _{K 2} to be used when calculating the power sale customer Distribution Amount alpha _s. Second coefficient K ₂ can be calculated by Equation 5 below.
K ₂ = Pv / TS (Formula 5)
Formula 5, in terms of the principle was to obtain the second coefficient K ₂ by dividing the area purchased electric power amount TB in area sold denden competence TS, area purchased electric power amount TB is area sold Denden competence If TS is greater than is the operation that the second coefficient K ₂ is set to "1".
The second coefficient K ₂ is the ratio of the amount of purchased electric power used by the electric power purchase consumer out of the total amount of electric power sold by the electric power selling customer to the in-area power system 3 in the electric power management area 1. Indicates.
Therefore, the second coefficient K ₁ indicates the energy in the area that indicates how much the power purchase customer in the same power management area 1 uses (purchases) the power output by the power sale customer in the power management area 1. Represents utilization η. That is, the second coefficient K ₂ = intra-area energy utilization rate η.

FIG. 6 shows the in-area energy self-sustained rate ε (first coefficient K) obtained in correspondence with the in-area purchased power amount TB, in-area sold power amount TS, and in-area effective interchangeable power amount Pv in FIG. ₁ ) and the in-area energy utilization rate η (second coefficient K ₂ ).
The in-area energy self-sustained rate ε is represented by a value obtained by dividing the in-area effective interchangeable power amount Pv by the in-area purchased power amount TB from the system. The in-area energy utilization rate η is represented by a value obtained by dividing the in-area effective interchangeable power amount Pv by the in-area power sale power amount TS.
The electric power generated by the solar cell 101 increases during the day, decreases in the evening or morning other than during the day, and becomes almost zero at night.
For this reason, the energy self-sustained ratio ε in the area increases during the day because much of the purchased power can be covered by the generated power of the solar cell 101 output by the power selling customer during the day, and the generated power of the solar cell 101 increases. Has a tendency to decrease at decreasing nighttime.
Contrary to the in-area energy self-sustained rate ε, the in-area energy utilization rate η decreases during the day because the surplus power generated by the solar cell 101 flows into the system during the day. In the morning and evening, the solar cell 101 Since the generated power or the surplus power of the storage battery 103 is used only in the power management area 1, it tends to increase.

Returning to FIG.
Step S108: profit sharing unit 205 calculates the power purchase consumer Distribution Amount alpha _b. Profit distribution section 205, in the calculation of the power purchase consumer Distribution Amount alpha _b, and acquires the specified power selling electricity unit price and defining purchased electricity power unit price corresponding to the current time from the specified trading electricity unit price storing unit 262. Also, profit sharing unit 205 obtains the first coefficient _{K 1} calculated by the step S106. Further, the profit distribution unit 205 acquires the profit distribution ratio from the profit distribution ratio storage unit 261.
Then, the profit sharing unit 205, the acquired specified purchased electric power cost per as described above, defines power selling electricity unit price, more buying electricity consumers Distribution Amount in Equation 6 below using the first coefficient K ₁ and profit distribution ratio α _b is calculated.

In Equation 6, C _b are defined purchased electric power cost per, C _s is defined power selling electricity unit price. Further, γ _b , γ _s , and γ _e are values of distribution ratios associated with electric power purchase consumers, electric power sales consumers, and electric power companies, respectively, in the profit distribution ratio. For example, as described above, if the value of “1” is associated with a power purchase consumer, “1” with a power sale consumer, and “1” with an electric power provider, respectively, in the profit sharing ratio, (γ _b = Γ _s = γ _e = 1).
The calculation expressed as (C _b −C _s ) in Equation 6, that is, the value obtained by subtracting the specified power sales unit price from the specified power purchase unit price, This is the amount to be distributed among the three electric utilities.
In addition, the calculation expressed as γ _b / (γ _b , γ _s , γ _e ) in Equation 6 is the distribution to the power purchase customers among the power purchase customer, the power sale customer, and the electric power company. Indicates the distribution rate of the target amount.

Step S109: The profit distribution unit 205 calculates a power sale customer distribution amount α _s . The profit distribution unit 205 obtains the specified power purchase unit price C _b and the specified power sale unit price C _s corresponding to the current time from the specified sale power unit price storage unit 262 in calculating the power sale consumer distribution amount α _s. . Also, profit sharing unit 205 acquires the second coefficient _{K 2} calculated by step S107. Further, the profit distribution unit 205 acquires the profit distribution ratio from the profit distribution ratio storage unit 261.
Then, the profit distribution unit 205 uses the specified power purchase unit price C _b , the specified power sale unit price C _s , the second coefficient K _2, and the profit share ratio acquired as described above to The customer distribution amount α _s is calculated.
The calculation expressed as γ _s / (γ _b , γ _s , γ _e ) in Equation 7 is the distribution ratio to the power selling customers among the power purchase customer, the power sale customer, and the electric power company. Show.

Step S110: profit sharing unit 205, a power purchase consumer Distribution Amount alpha _b calculated in the step S108, and stores the power sale customer Distribution Amount alpha _s calculated in the step S109 to the distribution amount storage unit 263.
Through the above processing, the distribution amount storage unit 263 stores the power purchase consumer distribution amount α _b and the power sale customer distribution amount α _s calculated at regular intervals. The power purchase consumer distribution amount α _b and the power sale customer distribution amount α _s stored in this way are used later to calculate an electricity charge for each consumer.

Specifically, the electricity charge for the charge calculation period for one consumer can be calculated as follows. The charge calculation unit 207 (FIG. 3) calculates the electricity charge.
In calculating the electricity rate for a single customer during the rate calculation target period, the rate calculation unit 207 calculates the unit price of purchased power and the unit price of sold power for a certain period of time during the rate calculation target period.

The charge calculation unit 207 calculates the purchased power unit price by subtracting the purchased power distribution amount α _b corresponding to the same fixed period from the specified purchased power unit price C _b corresponding to one fixed time. In other words, the purchased power unit price CB at regular time intervals is obtained by the following formula 8.
CB = C _b −α _b (Expression 8)
That is, the power purchase unit price CB is an amount obtained by reducing the power purchase consumer distribution amount α _b from the specified power purchase unit price C _b .

In addition, the charge calculation unit 207 calculates the power sale power unit price by subtracting the power sale customer distribution amount α _s corresponding to the same fixed period from the specified power sale unit price C _s corresponding to one fixed time. To do. That is, the electric power selling unit price CS for every fixed time is obtained by the following formula 9.
CS = C _s + α _s (Equation 9)
That is, the power selling power unit price CS is an amount obtained by increasing (adding) the power selling customer distribution amount α _s to the specified power selling power unit price C _s . In this way, the power selling customer receives the profit distribution by performing the increase by the power selling customer distribution amount α _s with respect to the specified power selling power unit price C _s .

  In addition, the charge calculation unit 207 multiplies the purchased power amount and the purchased power unit price every fixed time in the charge calculation target period, and accumulates the amounts obtained by the multiplication. The amount obtained by integrating in this way becomes the power purchase fee in the electricity bill.

  In addition, the fee calculation unit 207 multiplies the amount of electric power sold for each fixed time in the fee calculation target period by the electric power sold unit price, and integrates the amount obtained by the multiplication. The amount obtained by integrating in this way becomes a power selling fee in the electricity bill.

Further, the distribution profit Bn of the electric power company when viewed as the unit price of electric power is expressed by the following formula 10.
_{Bn = (C b -C s)} - (α b + α s) ··· ( Formula 10)
That is, the distribution profit Bn of the electric power company is obtained by subtracting the power purchase consumer distribution amount α _b and the power sale customer distribution amount α _s from the distribution target amount.
The charge calculation unit 207 can calculate the distribution profit amount of the electric power company in the charge calculation target period using the distribution profit Bn obtained by the above equation 10 as follows. That is, the fee calculation unit 207 calculates the distribution profit Bn for each fixed time in the charge calculation target period, and integrates the calculated distribution profit Bn for each fixed time. The amount obtained by the integration becomes the distribution profit amount of the electric power company during the charge calculation target period.

The power purchase consumer distribution amount α _b is a reduction from the specified power purchase unit price C _{b in the} power purchase unit price, and therefore increases as the in-area energy self-sustained rate ε, which is the first coefficient K ₁ , increases.
When the power sale power increases relative to the power purchase power, surplus power sale power is generated without being available in the power management area 1. Therefore, the state in which the power sale power included in the power purchase power is large is a state in which the customer wants to promote power purchase. Such benefits purchased power consumer Distribution Amount alpha _b is dispensed as the consumer be performed is power purchase power purchase consumer in a high state is increased. Accordingly, it is possible to effectively promote power purchase by notifying the consumer by display in a state where the power sale power included in the power purchase power is increased.

Since the power selling customer distribution amount α _s is an increase from the specified power selling power unit price C _{s in the} power selling power unit price, the higher the in-area energy utilization rate η, which is the second coefficient K ₂ , becomes higher.
When the purchased power increases relative to the sold power, the sold power that can be used in the power management area 1 is insufficient. Therefore, the state in which the purchased power included in the sold power is large is a state in which the customer wants to promote the power sale. If the consumer sells power in such a state where the power sale consumer distribution amount α _s is high, the profit distributed as a power sale consumer also increases. Accordingly, in the present embodiment, it is possible to effectively promote power sale by notifying a consumer by display under a state where the purchased power included in the sold power is increasing.

Intra-area purchased power amount TB, in-area sold power amount TS and in-area effective interchangeable power amount Pv shown in FIG. 5, in-area energy self-sustained rate ε (first coefficient K ₁ ) and in-area energy shown in FIG. The utilization factor η (second coefficient K ₂ ) corresponds to the case where the power generated by the solar cell 101 is output as the sold power. That is, in the description so far, a case where control is performed so that the power generated by the solar cell 101 in the power management area 1 is output as sold power is taken as an example.
However, in this embodiment, the power management area 1 may be controlled so as to output the power stored in the storage battery 103 as the selling power instead of the solar battery 101. When power selling power is output from the storage battery 103, as an example, the storage battery 103 can be operated by the facility-specific control unit 107 in each customer facility 10 as follows.
That is, for example, the storage battery 103 is charged using late-night power in a predetermined time zone at night. In addition, for example, the power stored in the storage battery 103 is output as sold power in a predetermined time zone corresponding to the evening when the power demand increases but the power generated by the solar battery 101 cannot be obtained. In addition, when outputting the electric power accumulate | stored in the storage battery 103 as electric power sales power, for example, when the surplus part arises using the electric power of the storage battery 103 with the load 106 of the consumer facility 10, the surplus part is made into electric power sale electric power. You may make it output, and without supplying the electric power of the storage battery 103 to the load 106, you may make it output to the in-area electric power system 3 as electric power selling power as it is.
In this way, even when the power output from the storage battery 103 is used as the selling power, the relationship among the purchased power amount TB in the area, the sold power amount TS in the area, and the effective interchangeable power amount Pv in the area conforms to FIG. It will be a thing. That is, although illustration is omitted, in the night time zone, the in-area purchased power amount TB is high, whereas the in-area sold power amount TS is low. On the other hand, during the daytime, the solar battery 101 generates power to reduce the amount of purchased power TB in the area, and in the time zone corresponding to the evening, the power stored in the storage battery 103 is used as the electric power for sale. As a result, the in-area purchased electric energy TB is generated. At this time, if the in-area purchased power amount TB is larger than “0” and the in-area purchased power amount TS is higher than the in-area purchased power amount TB, the in-area effective power corresponding to the in-area purchased power amount TB is obtained. An accommodation power amount Pv is obtained. In addition, the energy self-sustained ratio ε (first coefficient K ₁ ) in the area for each time zone is obtained by the calculation of Expression 4 and Expression 5 using the in-area purchased power amount TB and the in-area power sale energy TS for each time period. An in-area energy utilization rate η (second coefficient K ₂ ) is obtained.

In the present embodiment, the electric power generated by the solar battery 101 and the electric power stored in the storage battery 103 may be used in combination to be output as sold power. In this case, for example, the power sale power can be output as follows. That is, under a state where the solar cell 101 can generate power during the day, the surplus power generated by the solar cell 101 without being used by the load 106 is output as sold power. Then, in a state where power generation cannot be performed by the solar battery 101 in the evening or at night, the power stored in the storage battery 103 is output as the sold power.
In the above example, the time zone in which the power generated by the solar battery 101 is output as the selling power is different from the time zone in which the power stored in the storage battery 103 is output as the selling power. However, for example, during the daytime, the power generated by the solar battery 101 and the power stored in the storage battery 103 can be simultaneously output as sold power.
