Description

  The present invention relates to a fee calculation device and a program.

  2. Description of the Related Art Conventionally, there has been proposed a technique for stably maintaining the supply and demand balance of a power network when various types of power sources are connected to the power network (for example, Patent Document 1).

JP 2011-193644 A

Here, among various types of power sources connected to the power network, there are consumers who want to receive power supply limited to a specific type. For example, there are customers who desire to use “electric power generated by a specific power generation method” or “electric power generated at a specific location”. With respect to this specific type of power source, a so-called specific power source may be branded, so that an electric power unit price different from that of other types of power sources may be attached.
On the other hand, if supply is limited and the type of power supply is limited, the supply-demand balance tends to be lost. If the supply and demand balance is disrupted and power supply from a specific type of power supply is insufficient, if power is supplied from another type of power supply, it will be difficult to determine the amount of power and calculate the charge based on the unit price of the power supply. In fact, it was difficult to brand specific power sources.
With the technology described in Patent Document 1, it may be possible to stably maintain the supply-demand balance, but the fee calculation when the supply-demand balance is lost is not taken into consideration. Therefore, the conventional technique has a problem in that even if a different power unit price is assigned for each type of power supply, it is not possible to calculate a charge. The present invention has been made in view of the above points, and provides a charge calculation device and a program that enable charge calculation according to the type of power supply when the type of power supply is limited.

A charge calculation device comprising: a check unit that checks the amount and the amount of power used for each type; and a charge calculation unit that calculates a power charge of the consumer based on a result of the check by the check unit .

  Further, in the charge calculation device according to one aspect of the present invention, the power usage contract information includes at least information indicating a plurality of different types, and the charge calculation unit includes the power usage contract with the amount of power used. The power plant of the second type different from the first type of the plurality of types when the amount of the generated power by the power plant of the first type of the plurality of types indicated by the information is exceeded The amount of the generated power and the amount of used power are collated.

  In the fee calculation apparatus according to one aspect of the present invention, the fee calculation unit calculates the power fee for each type.

  In addition, the charge calculation device according to one aspect of the present invention calculates, for each type, a relative value between the amount of generated power and the amount of power used as a power generation surplus in response to the verification performed by the verification unit. A power generation surplus calculation unit is further provided.

[Embodiment]
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating an example of a configuration of a power charge calculation system 1 according to the present embodiment. The power charge calculation system 1 calculates a charge for power supplied from the power plant PP to the customer CS via the power network N.

[Type of power plant and branding of generated power]
The kind of power plant PP is demonstrated. Various types of power plants PP are determined depending on the power generation method, location, and the like. As an example, the power plant PP01 has a power generation method of “LNG (Liquid Natural Gas) thermal power”. In this case, the type of the power plant PP01 is defined as “power generation method: LNG thermal power”. Further, the power plant PP01 is located at “A city”. In this case, the type of the power plant PP01 is defined as “location: city A”.
As an example, the power plant PP08 has a “hydropower” power generation method. In this case, the type of the power plant PP08 is defined as “power generation method: hydraulic power”. Further, the power plant PP08 is located at “F village”. In addition, the power plant PP08 generates power using the water flow of the “G River” flowing through the F village. In this case, the type of the power plant PP08 is defined as “location: village F river G”.
In addition, the kind of power plant PP shown here is an example, Comprising: As long as a kind can be distinguished between power plants PP, it is not restricted to a power generation system and a location.

Here, there is a customer CS who desires to use “electric power generated by a specific power generation method” or “electric power generated at a specific location”.
For example, in the case where the customer CS01 is a beverage manufacturing factory, there is a case where the beverage sales force can be enhanced by branding the name of the water source of the beverage, which is the raw material of the beverage.
As in the case of the water source, there is a case where the beverage sales power can be enhanced by branding the power supply source used by the customer CS01 for beverage production, that is, the power generation system and name of the power plant PP. is there.
Specifically, when the water source is “F village G river”, the power generation method of the power plant PP is “hydropower”, and the location of the power plant PP is “F village G river”, the customer CS01 By branding that this beverage is from “F Village G River”, the sales power of the beverage may be increased.
In this case, if the customer CS01 is not the power plant PP01 whose location is “A city” but the power plant PP08 whose location is “F village G river”, for example, It can be branded that the beverage is from "F Village G River".
The specific power source to be branded has a higher competition rate when the customer CS purchases it. Therefore, the unit price of the specific power source should be set higher than the unit price of other non-branded power sources. Can do.
In the following description, “power generated by a specific power generation method” and “power generated at a specific location” are also simply referred to as “specific types of power”.

The electric power network N is supplied with electric power generated by a plurality of power plants PP. If the type of the power plant PP can be selected on the customer CS side for the power supplied from the power network N, the power can be branded according to the type of the power plant PP. In order to implement the above-mentioned power branding, that is, “specific power supply branding”, a supply-demand balance is established between the power generated by a specific type of power plant PP and the power used by the customer CS. Is required.
Here, when the power source is specified, the demand may exceed the supply capacity of the power source. In this case, the supply-demand balance is lost. Therefore, when the supply-demand balance is lost, the supply-demand balance is established by supplying power from a power source other than the specific power source (by performing so-called power mixing).
However, when the power unit price is different between the specific power source and a power source other than the specific power source, it is practically difficult to calculate the power rate when the power mix is performed.
The power rate calculation system 1 according to the present embodiment compares the power generated by a specific type of power plant PP with the power used by the customer CS to avoid the above-described difficulty, thereby Even when different electric powers are mixed, the electric power charge can be calculated. Hereinafter, the configuration of the power rate calculation system 1 will be described.

[Configuration of power charge calculation system 1]
The power rate calculation system 1 includes a power plant side meter MP, a consumer side meter MC, a fee calculation device 10, and an output device 20.

The power plant side meter MP includes, for example, a watt-hour meter, and measures the amount of power generated by the power plant PP. The “amount of generated power” here includes any meaning of an amount obtained by integrating the generated power on the time axis, that is, the amount of power, and an amount of generated power per unit time, that is, power. In the present embodiment, the case where the “amount of generated power” is not “power” but “power amount” will be described as an example.
The power plant side meter MP supplies the charge calculation device 10 with generated power amount information GE indicating the measured amount of generated power.
The power plant side measuring instrument MP is installed for each power plant PP. In this example, there are n power plants PP from power plant PP01 to power plant PPn. n is a natural number. In this case, n power plant side measuring devices MP are installed from the power plant measuring device MP01 to the power plant measuring device MPn corresponding to the power plant PP01 to the power plant PPn.
In the following description, when the power plants PP01 to PPn are not individually distinguished, they are collectively referred to as a power plant PP. Moreover, when not distinguishing individually from power station side measuring instrument MP01 to power station side measuring instrument MPn, it is named generically as power station side measuring instrument MP.

The consumer-side meter MC includes, for example, a watt-hour meter, and measures the amount of power used by the consumer CS. The term “amount of power used” here includes both the amount of power used integrated on the time axis, that is, the amount of power, and the amount of power used per unit time, that is, power. In the present embodiment, the case where the “amount of power used” is not “power” but “power amount” will be described as an example.
The consumer-side meter MC supplies the power consumption amount information UE indicating the measured amount of used power to the charge calculation device 10.
A consumer-side meter MC is installed for each consumer CS. In this example, there are m customer CSs from the customer CS01 to the customer CSm. m is a natural number. In this case, m customer-side measuring instruments MC are installed from the consumer-side measuring instrument MC01 to the customer-side measuring instrument MCm in correspondence with the consumers CS01 to the customer CSm.
In addition, in the following description, when it does not distinguish separately from the consumer side measuring device MC01 to the consumer side measuring device MCm, it is named generically as the consumer side measuring device MC.

The charge calculation device 10 calculates a power charge based on the generated power amount information GE supplied by the power plant side meter MP and the used power amount information UE supplied by the consumer side meter MC. The charge calculation device 10 supplies the calculated power charge to the output device 20 as billing information BI.
The output device 20 outputs the billing information BI supplied from the fee calculation device 10 to the customer CS. Here, the output includes printing, display on a screen, supply of billing information BI via an information storage medium, and supply of billing information BI via a network.

[Configuration of charge calculation device]
A functional configuration of the fee calculation apparatus 10 will be described with reference to FIG.
FIG. 2 is a diagram illustrating an example of a functional configuration of the fee calculation apparatus 10 according to the present embodiment. The charge calculation device 10 includes a generated power amount information acquisition unit 110, a used power amount information acquisition unit 120, a verification unit 130, a charge calculation unit 140, and a power generation surplus calculation unit 150 as functional units. In addition, the fee calculation apparatus 10 includes a power plant information storage unit 160, a contract information storage unit 170, and a power unit price information storage unit 180.

  The generated power amount information acquisition unit 110 acquires the generated power amount information GE from the power plant side meter MP. An example of the generated power amount information GE acquired by the generated power amount information acquisition unit 110 will be described with reference to FIG.

FIG. 3 is a diagram illustrating an example of the generated power amount information GE acquired by the generated power amount information acquiring unit 110 according to the present embodiment. The generated power amount information acquisition unit 110 acquires the generated power amount information GE01 (FIG. 3A). The generated power amount information GE01 is information indicating the amount of generated power of the power plant PP01 measured by the power plant side meter MP01.
Further, the generated power amount information acquisition unit 110 acquires the generated power amount information GE02 (FIG. 3B). The generated power amount information GE02 is information indicating the amount of generated power of the power plant PP02 measured by the power plant side meter MP02.
In the same manner as described above, the generated power amount information acquisition unit 110 acquires the generated power amount information GE from each power station-side meter MP.
That is, the generated power amount information acquisition unit 110 acquires the generated power amount information GE indicating the amount of generated power from the power station-side meter MP that measures the amount of generated power output from the power plant PP.

  The generated power amount information GE will be described more specifically. The power plant side meter MP associates the power plant ID, the measured time (time stamp), and the measured power amount and supplies the generated power amount information GE to the charge calculation device 10. Here, the power plant ID is identification information uniquely assigned to each power plant PP. The generated power amount information acquisition unit 110 extracts the power plant ID from the acquired generated power amount information GE, thereby identifying which power plant PP indicates the generated power amount of the generated power amount information GE. . For example, if the power plant ID of the acquired power generation amount information GE is “PP01”, the power generation amount information acquisition unit 110 is information indicating the power generation amount of the power plant PP01. Identify it.

  Further, the generated power amount information acquisition unit 110 acquires the generated power amount information GE at predetermined time intervals. In this example, the generated power amount information acquisition unit 110 acquires the generated power amount information GE at intervals of 30 minutes. In the specific example shown in FIG. 3A, the generated power amount information acquisition unit 110 acquires the power plant ID “PP01”, the time stamp “2016: 09: 01: 15: 00”, and the generated power amount “5000 kWh”. . Here, the power plant ID “PP01” indicates that the generated power amount information GE is information about the power plant PP01. The time stamp “2016: 09: 01: 15: 00” indicates that the measured date and time is 15:00 on September 1, 2016. The generated power amount “5000 kWh” indicates that the measured generated power amount is 5000 kWh.

In this example, the power plant side meter MP initializes the measured power generation amount to 0 kWh for each metering cycle. Specifically, when the power plant side meter MP measures the amount of generated power at intervals of 30 minutes, the integrated value of the generated power for 30 minutes is measured as “generated power amount”, and the generated power amount information GE Is generated. When generating power generation amount information GE, the power plant side measuring instrument MP initializes the integrated value to 0 kWh and performs the measurement for the next 30 minutes.
Note that the power plant side measuring instrument MP does not measure the integrated value by initializing the integrated value when generating the generated electric energy information GE, but instead calculates the difference between the previous measured value and the current measured value. May be weighed as

  In the example shown in FIG. 3A, the integrated value of the generated power for 30 minutes from 14:30 to 15:00 on September 1, 2016 is “5000 kWh” for the power plant PP01. The integrated value of the generated power for 30 minutes from 15:00 to 15:30 on the same day is the generated power amount “4500 kWh”. The integrated value of the generated power for 30 minutes from 15:30 to 16:00 on the same day is the generated power amount “4800 kWh”.

  In the example shown in FIG. 3B, for the power plant PP02, the integrated value of the generated power for 30 minutes from 14:30 to 15:00 on September 1, 2016 is the generated power amount “10000 kWh”. The integrated value of the generated power for 30 minutes from 15:00 to 15:30 on the same day is the generated power amount “9800 kWh”. The integrated value of the generated power for 30 minutes from 15:30 to 16:00 on the same day is the generated power amount “9900 kWh”.

Returning to FIG. 2, the power plant information storage unit 160 stores power plant information PI. An example of the power plant information PI will be described with reference to FIG.
FIG. 4 is a diagram illustrating an example of the power plant information PI stored in the power plant information storage unit 160 of the present embodiment. In the power plant information storage unit 160, a power plant ID and a power plant type are associated with each other and stored as power plant information PI. This power plant type includes the power generation method of the power plant PP and the location of the power plant PP. Specifically, the power plant information storage unit 160 stores a power plant ID “PP01”, a power generation method “LNG thermal power”, and a location “A city” in association with each other for the power plant PP01. .
Similarly, in the power plant information storage unit 160, a power plant ID “PP02” and a power generation method “crude oil thermal power” and a location “A city” are generated for the power plant PP02, and a power plant ID “PP03” is generated for the power plant PP03. The system “city gas thermal power” and the location “B city” are stored in association with each other.
The power plant information storage unit 160 stores power plant information PI for the other power plants PP in the same manner as described above. For example, in the power plant information storage unit 160, the power plant ID “PP07”, the power generation method “hydraulic power” and the location “F village” are generated for the power plant PP07, and the power plant ID “PP08” is generated for the power plant PP08. The method “hydraulic power” and the location “F village G river” are stored in association with each other.

  Returning to FIG. 2, the used power amount information acquisition unit 120 acquires the used power amount information UE from the consumer-side meter MC. An example of the used power amount information UE acquired by the used power amount information acquisition unit 120 will be described with reference to FIG.

FIG. 5 is a diagram illustrating an example of the used power amount information UE acquired by the used power amount information acquisition unit 120 of the present embodiment. The used power amount information acquisition unit 120 acquires the used power amount information UE01 (FIG. 5A). The power consumption information UE01 is information indicating the amount of power used by the consumer CS01 measured by the consumer meter MC01.
Moreover, the used electric energy information acquisition part 120 acquires used electric energy information UE02 (FIG. 5 (B)). This power consumption information UE02 is information indicating the amount of power used by the consumer CS02 measured by the consumer meter MC02.
In the same manner as described above, the used power amount information acquisition unit 120 acquires the used power amount information UE from each consumer-side meter MC.
That is, the used power amount information acquisition unit 120 acquires the used power amount information UE indicating the amount of used power from the consumer-side meter MC that measures the amount of used power used by the customer CS.

  The power consumption information UE will be described more specifically. The consumer-side meter MC supplies the consumer ID, the measured time (time stamp), and the measured power amount to the charge calculation device 10 as the used power amount information UE in association with each other. Here, the customer ID is identification information uniquely assigned to each customer CS. The used power amount information acquisition unit 120 extracts a consumer ID from the acquired used power amount information UE, thereby identifying which consumer CS the used power amount of the used power information UE is information about. . For example, when the customer ID of the acquired power consumption information UE is “CS01”, the power consumption information acquisition unit 120 is information indicating the power consumption of the customer CS01. Identify it.

  Moreover, the used electric energy information acquisition part 120 acquires the used electric energy information UE at a predetermined time interval. In this example, the used power amount information acquisition unit 120 acquires the used power amount information UE at intervals of 30 minutes. In the specific example shown in FIG. 5A, the power consumption information acquisition unit 120 acquires the customer ID “CS01”, the time stamp “2016: 09: 01: 15: 00”, and the power consumption “100 kWh”. . Here, the customer ID “CS01” indicates that the power consumption information UE is information about the customer CS01. The time stamp “2016: 09: 01: 15: 00” indicates that the measured date and time is 15:00 on September 1, 2016. The used electric energy “100 kWh” indicates that the measured used electric energy is 100 kWh.

In this example, the consumer-side meter MC initializes the measured power consumption to 0 kWh for each metering cycle. Specifically, when the consumer-side meter MC measures the amount of power used at 30-minute intervals, the integrated value of the power used for 30 minutes is measured as “power consumption”, and the power consumption information UE Is generated. When the consumer-side meter MC generates the power consumption information UE, the consumer-side meter MC initializes the integrated value to 0 kWh and performs the next 30 minutes of measurement.
Note that the consumer-side meter MC does not measure the integrated value by initializing the integrated value when the power consumption information UE is generated, but calculates the difference between the previous measured value and the current measured value. May be weighed as

  In the example shown in FIG. 5A, for the customer CS01, the integrated value of the power used for 30 minutes from 14:30 to 15:00 on September 1, 2016 is the power consumption “100 kWh”. The integrated value of power consumption for 30 minutes from 15:00 to 15:30 on the same day is the power consumption “120 kWh”. The integrated value of power consumption for 30 minutes from 15:30 to 16:00 on the same day is the power consumption “110 kWh”.

  In the example shown in FIG. 5 (B), for the customer CS02, the integrated value of the power used for 30 minutes from 14:30 on September 1, 2016 to 15:00 is the power consumption “10 kWh”. The integrated value of power used for 30 minutes from 15:00 to 15:30 on the same day is the power consumption “9 kWh”. The integrated value of power consumption for 30 minutes from 15:30 to 16:00 on the same day is the power consumption “10 kWh”.

Returning to FIG. 2, the contract information storage unit 170 stores power usage contract information CI. An example of the power usage contract information CI will be described with reference to FIG.
FIG. 6 is a diagram illustrating an example of the power usage contract information CI stored in the contract information storage unit 170 of the present embodiment. The contract information storage unit 170 stores customer ID, power plant type, and contract power in association with each other as power usage contract information CI. Here, the contract information storage unit 170 stores the power plant type and the contract power in association with each contract stage.

Specifically, in the contract information storage unit 170, for the customer CS01, the customer ID “CS01”, the power plant type “F village G river hydroelectric power generation” and the contract power “50 kW” in the contract stage 1 are contracted. The power plant type “F village river not specified hydroelectric power generation” and contracted power “100 kW” in stage 2 and the power plant type “regional unspecified hydroelectric power generation” and contract power “100 kW” in contracted stage 3 are stored in association with each other. Has been.
In addition, the contract information storage unit 170 stores the customer ID “CS02”, the power plant type “regional designation-free hydropower generation” and the contract power “100 kW” of the contract stage 1 and the power generation of the contract stage 2 for the customer CS02. The plant type “no power plant type designation” and the contract power “100 kW” are stored in association with each other.
In the contract information storage unit 170, for the customer CS03, the customer ID “CS03”, the power plant type “no area designation CO2 emission” and the contract power “20 kW” in the contract stage 1, the contract stage 2 The power plant type “no power plant type designation” and the contract power “20 kW” are stored in association with each other.

Returning to FIG. 2, the collation unit 130 collates the amount of generated power and the amount of used power for each type based on the power usage contract information CI, the generated power amount information GE, and the used power amount information UE. Specifically, the collation unit 130 acquires the generated power amount information GE from the generated power amount information acquisition unit 110. The verification unit 130 acquires the used power amount information UE from the used power amount information acquiring unit 120. The verification unit 130 acquires the power plant information PI from the power plant information storage unit 160. The verification unit 130 acquires the power usage contract information CI from the contract information storage unit 170.
The collation unit 130 identifies the type of generated power by collating the generated power amount information GE and the power plant information PI. The verification unit 130 identifies the type of power used based on the power usage information UE and the power usage contract information CI. Based on these identification results, the collating unit 130 collates the type of power generated and the type of power used.
The collation unit 130 supplies the collation result to the fee calculation unit 140.

  The charge calculation unit 140 calculates the power charge of the customer CS based on the verification result RC by the verification unit 130 and the power unit price information UP stored in the power unit price information storage unit 180.

FIG. 7 is a diagram illustrating an example of the power unit price information UP stored in the power unit price information storage unit 180 of the present embodiment. In the power unit price information storage unit 180, the power plant ID, the power unit price, and the CO2 emission coefficient are associated with each other and stored as the power unit price information UP. Specifically, for the power plant PP01, a power plant ID “PP01”, a power unit price “24 (yen / kWh)”, and a CO 2 emission coefficient “0.0135” are stored in association with each other. Further, for the power plant PP02, a power plant ID “PP02”, a power unit price “20 (yen / kWh)”, and a CO 2 emission coefficient “0.0187” are stored in association with each other.
Similarly, in the power unit price information storage unit 180, the power plant ID, the power unit price, and the CO2 emission coefficient are stored in association with each other for the other power plants PP.

Here, in the case where the power generation system of the power plant PP is a system that generates power without burning fossil fuel, such as sunlight, wind power, geothermal power, hydraulic power, etc., compared with a system that generates power with combustion of fossil fuel, CO 2 Low emission factor. Here, the customer CS may advertise for a certain product or service that the power used to manufacture / sell the product or provide the service is generated by a specific power generation method. In this case, the power generation method with a low CO2 emission coefficient may have a higher advertising effect than the power generation method with a high CO2 emission coefficient. In this case, even if the unit price of the power generated by the power generation method without fossil fuel combustion is set higher than the unit price of the power generated by the power generation method with fossil fuel combustion, the customer CS Purchase power with a high unit price.
In addition, there is a case where a product or service provided by the customer CS is highly related to a specific area or environment (for example, a river). Here, the customer CS is the power used for the manufacture / sales of the product and the provision of the service is the power generated in a specific region, or generated using the flow of a specific river May advertise that it is electricity. In this case, the higher the relevance between the product or service provided by the customer CS and the region or environment (for example, a river) where power is generated, the higher the advertising effect may be compared to the case where the relevance is low. . In this case, for example, even if the unit price of the power generated using a specific river flow is set higher than the unit price of the power generated without using the specific river flow, the customer CS Buy power with a high unit price.
That is, different power unit prices are set in the power unit price information UP for each type of power plant PP.

The power generation surplus calculation unit 150 calculates a relative value between the amount of generated power and the amount of power used for each type as the power generation surplus according to the collation performed by the collation unit 130.
Specifically, the power generation surplus calculation unit 150 generates power generation surplus information based on the power generation energy information GE supplied by the power plant side meter MP and the power usage information UE supplied by the consumer meter MC. A PGC is generated for each type of generated power. The power generation surplus calculation unit 150 outputs the generated power generation surplus information PGC to the output device 20. Here, the power generation surplus is a relative value between the amount of generated power and the amount of power used. This relative value includes the ratio between the amount of generated power and the amount of power used, and the difference between the amount of generated power and the amount of power used. For example, when the relative value is the ratio between the amount of generated power and the amount of power used, the power generation surplus calculation unit 150 generates the ratio between the amount of generated power and the amount of power used for each power plant PP. Calculate as available power.
That is, the power generation surplus calculation unit 150 calculates, as the power generation surplus, how much surplus power the power generated by the power plant PP has compared to the power used by the customer CS. The fee calculation device 10 generates power generation surplus information PGC indicating the calculated power generation surplus, and supplies the generated power generation surplus information PGC to the output device 20.

In this example, the collation unit 130 acquires the power usage information UE shown in FIG.
(Step S40) The collation unit 130 acquires the power usage contract information CI from the contract information storage unit 170. In this example, the collation unit 130 acquires the power usage contract information CI shown in FIG.
In addition, although the figure shows an example in which step S10 and step S20 and step S30 and step S40 are processed in parallel with each other, the present invention is not limited to this. As an example, step S10 to step S40 may be sequentially processed.
Next, specific operations of the collation unit 130 and the charge calculation unit 140 will be described separately for each case. In the following description, it is assumed that the current time is “September 1, 2016, 15:00”.

[Verification of electric energy (stepwise verification)]
(Step S50) The fee calculation unit 140 calculates the fee for the contract stage 1 for each customer CS based on the verification result RC of the verification unit 130.

Specifically, the collation unit 130 collates the customer CS01 at the contract stage 1 in the power usage contract information CI shown in FIG. In this case, the collation unit 130 identifies that the power plant type at the contract stage 1 of the customer CS01 is “F village G river hydroelectric power generation” based on the power usage contract information CI shown in FIG. Next, the collation unit 130 identifies that the current power consumption of the customer CS01 is “100 kWh” based on the power consumption information UE shown in FIG. Next, the collation unit 130 identifies that the power plant PP of “F village G river hydroelectric power generation” is “power plant PP08” based on the power plant information PI shown in FIG. 4. Next, the verification unit 130 identifies that the current power generation amount of the power plant PP08 is “50 kWh” based on the power generation amount information GE shown in FIG.
Here, based on the above identification result, the collation unit 130 is short of the current power generation amount “50 kWh” of the power plant PP08 relative to the current power consumption amount “100 kWh” of the customer CS01. Is determined.
Moreover, the collation part 130 outputs the collation result RC which shows that the part for "50 kWh" is the electric energy supplied from power plant PP08 among the current electric power consumption "100 kWh" of consumer CS01.
The charge calculation unit 140 calculates the first-stage power charge of the customer CS01 based on the verification result RC of the verification unit 130. More specifically, the charge calculation unit 140 determines that the customer CS01 has used “50 kWh” of the electric power of the unit price “35 (yen / kWh)” supplied from the power plant PP08, and the customer CS01 A charge “1750 yen” is calculated as a one-stage power charge.

(Step S60) When it is determined that the generated power is insufficient in the contract stage 1 of the customer CS01 (Step S60; YES), the collation unit 130 advances the process to Step S70. When it is determined that the generated power is not insufficient in the contract stage 1 of the customer CS01 (step S60; NO), the collation unit 130 advances the process to step S110.
In this example, as described above, the collation unit 130 determines that the current power generation amount “50 kWh” of the power plant PP08 is insufficient with respect to the current power consumption amount “100 kWh” of the customer CS01. doing. Therefore, the collation part 130 advances a process to step S70.

(Step S <b> 70) The fee calculation unit 140 calculates the fee for the contract stage 2 for each customer CS based on the verification result RC of the verification unit 130.

Specifically, the collation unit 130 collates the customer CS01 at the contract stage 2 in the power usage contract information CI shown in FIG. In this case, the collation unit 130 identifies that the power plant type at the contract stage 1 of the customer CS01 is “F village river not specified hydropower generation” based on the power usage contract information CI shown in FIG. Next, the collation unit 130 searches for the power plant PP corresponding to “F village river not specified hydroelectric power generation” based on the power plant information PI shown in FIG. 4, and generates “F village hydroelectric power generation” as a result of the search. The plant PP is identified as “power plant PP07”. Next, the collation unit 130 identifies that the current power generation amount of the power plant PP07 is “100 kWh” based on the power generation amount information GE shown in FIG. Next, the collation unit 130 identifies that the power shortage determined in step S50 is “50 kWh”.
Here, based on the above identification result, the collation unit 130 determines that the power deficiency “50 kWh” of the customer CS01 can be covered by the current power generation amount “100 kWh” of the power plant PP07.
In addition, the verification unit 130 subtracts “50 kWh” borne by the power plant PP08 from the current power consumption “100 kWh” of the customer CS01, that is, “50 kWh” is the power supplied from the power plant PP07. The collation result RC indicating that the amount is present is output.
The charge calculation unit 140 calculates the second-stage power charge of the customer CS01 based on the verification result RC of the verification unit 130. More specifically, the charge calculation unit 140 determines that the customer CS01 has used “50 kWh” of the unit price “32 (yen / kWh)” supplied from the power plant PP07, and the customer CS01 A charge “1600 yen” is calculated as a two-stage power charge.

(Step S80) When it is determined that the generated power is insufficient in the contract stage 2 of the customer CS01 (Step S80; YES), the collation unit 130 advances the process to Step S90. When it is determined that the generated power is not insufficient in the contract stage 2 of the customer CS01 (step S80; NO), the collation unit 130 advances the process to step S110.
In this example, as described above, the collation unit 130 compares the current power consumption “50 kWh” of the power plant PP08 with the current power consumption “100 kWh” of the customer CS01 and the current power of the power plant PP07. It is determined that the amount of generated power was covered by “100 kWh”. Therefore, the collation part 130 advances a process to step S110.

That is, when the amount of power used exceeds the amount of power generated by the first type power plant PP among the plurality of types indicated by the power usage contract information CI, The amount of power generated by the second type power plant PP different from the first type is compared with the amount of power used. In this example, the “first type power plant PP” is the power plant PP of “F village G river hydroelectric power generation”, that is, the power plant PP08. In this example, the “second type power plant PP” is a power plant PP of “F village hydroelectric power generation”, that is, a power plant PP07.
That is, the charge calculation unit 140 collates the plurality of types of power plants PP indicated by the power usage contract information CI step by step based on the contract stage of the power usage contract information CI.

  In step S90 and step S100, the collation unit 130 and the fee calculation unit 140 perform the same operations as the operations in step S70 and step S80 described above, and thus description thereof is omitted.

(Step S110) The fee calculation unit 140 totals the fees calculated in each contract stage. In this example, the charge calculation unit 140 calculates the total charge “3350 yen” for the customer CS01 by adding the charge “1750 yen” at the contract stage 1 and the charge “1600 yen” at the contract stage 2. .

  Here, the charge at each contract stage is a charge calculated for each type of power plant PP. That is, the charge calculation unit 140 calculates the power charge for each type of power plant PP.

(Step S120) The fee calculation unit 140 outputs the calculated total fee and the fee at each contract stage to the output device 20 as billing information BI.
The collation unit 130 and the charge calculation unit 140 output the billing information BI to the output device 20 for each customer CS by repeatedly executing the processes from step S50 to step S120 for each customer CS.

[Verification of electric energy (variation of stepwise verification)]
The operations from step S50 to step S110 described above may be modified as follows. Note that the description of the same operations as those from step S50 to step S110 described above is omitted.

(Step S50-1) The fee calculation unit 140 calculates the fee for the contract stage 1 for each customer CS based on the verification result RC of the verification unit 130.
Here, based on the above identification result, the collation unit 130 is short of the current power generation amount “50 kWh” of the power plant PP08 relative to the current power consumption amount “100 kWh” of the customer CS01. Is determined. When the verification result RC of the verification unit 130 indicates that the generated power is insufficient in the contract stage 1, the charge calculation unit 140 does not calculate the power charge of the contract stage 1. In this case, the charge calculation unit 140 may calculate the power charge of the contract stage 1 as “0 yen”. That is, when the amount of generated power is insufficient with respect to the amount of power used at a certain contract stage, the charge calculation unit 140 does not calculate a charge based on the contract stage.

(Step S60-1) The collation part 130 advances a process to step S70-1, when it determines with the generated electric power being insufficient in the contract phase 1 of the consumer CS01 (step S60-1; YES). When it is determined that the generated power is not insufficient in the contract stage 1 of the customer CS01 (step S60-1; NO), the collation unit 130 advances the process to step S110.
In this example, as described above, the collation unit 130 determines that the current power generation amount “50 kWh” of the power plant PP08 is insufficient with respect to the current power consumption amount “100 kWh” of the customer CS01. doing. Therefore, the collation part 130 advances a process to step S70-1.

(Step S <b> 70-1) The fee calculation unit 140 calculates a fee for the contract stage 2 for each customer CS based on the verification result RC of the verification unit 130.
Here, based on the above identification result, the collation unit 130 determines that the power deficiency “50 kWh” of the customer CS01 can be covered by the current power generation amount “100 kWh” of the power plant PP07. If the verification result RC of the verification unit 130 indicates that the generated power is not insufficient in the contract stage 2, the charge calculation unit 140 calculates the power charge in the contract stage 2.

In step S70 described above, a second-stage power charge is calculated with respect to the remaining power consumption subtracted by the power charge calculation procedure of the contract stage 1 out of the current power consumption of the customer CS01.
On the other hand, in step S70-1 of this modification, a second-stage power charge is calculated for the entire amount of current power consumption of the customer CS01.
Specifically, the charge calculation unit 140 calculates the second-stage power charge of the customer CS01 based on the verification result RC of the verification unit 130. More specifically, when the amount of power used by the customer CS01 is “100 kWh”, the charge calculation unit 140 has a unit price “32 (yen / kWh)” supplied from the power plant PP07 by the customer CS01. It is determined that “100 kWh” of electric power has been used, and the charge “3200 yen” is calculated as the second-stage electric power charge of the customer CS01.

(Step S80-1) The collation part 130 advances a process to step S90-1 when it determines with the generated electric power being insufficient in the contract phase 2 of the consumer CS01 (step S80-1; YES). When it is determined that the generated power is not insufficient in the contract stage 2 of the customer CS01 (step S80-1; NO), the collation unit 130 advances the process to step S110.
In this example, as described above, the collation unit 130 determines that the current power consumption “100 kWh” of the customer CS01 is covered by the current power generation power “100 kWh” of the power plant PP07. Yes. Therefore, the collation part 130 advances a process to step S110.

(Step S110) The fee calculation unit 140 totals the fees calculated in each contract stage. In this example, the charge calculation unit 140 calculates the total charge “3200 yen” for the customer CS01 by adding the charge “0 yen” at the contract stage 1 and the charge “3200 yen” at the contract stage 2. .

[Verification of electric energy (concept of real-time verification)]
Moreover, the collation part 130 and the charge calculation part 140 perform real-time collation with the generated electric energy and the used electric energy by executing each step described above at a predetermined time interval (for example, every 30 minutes).
The concept of real-time collation between the generated power amount and the used power amount will be described with reference to FIG.
FIG. 9 is a diagram illustrating an example of a temporal change in power used by the customer CS and a temporal change in generated power at the power plant PP according to the present embodiment. In this example, the electric power P1 used by a certain customer CS (for example, customer CS01) from 0 o'clock to 24 o'clock changes as a waveform W1 shown in the figure. Further, in this example, the generated power P2 generated by a certain power plant PP (for example, power plant PP08) changes as shown by a waveform W2 shown in FIG. Here, in the period from 0 o'clock to 6 o'clock and the period from 18 o'clock to 24 o'clock, the generated power P2 exceeds the used electric power P1. That is, since the supply is larger than the demand during the period from 0 o'clock to 6 o'clock and from 18 o'clock to 24 o'clock, the electric power used by the customer CS01 can be provided only by the power plant PP08. On the other hand, during a period from 6 o'clock to 18 o'clock at time t, the generated power P2 is lower than the used power P1. That is, since the demand is larger than the supply during the period from 6 o'clock to 18 o'clock, the power used by the customer CS01 cannot be supplied only by the power plant PP08. In this case, the electric power used by the customer CS01 is supplied from a power plant PP other than the power plant PP08 (for example, the power plant PP07).

In this case, the charge calculation device 10 determines the unit price of the power plant PP08 (35 shown in FIG. 7) for the consumer CS01 during the period from 0 o'clock to 6 o'clock and from 18 o'clock to 24 o'clock. Yen / kWh) to calculate the electricity charge.
Further, during the period from 6 o'clock to 18 o'clock time, the unit price of the power plant PP08 (35 yen / kWh shown in FIG. 7) and the unit price of the power plant PP07 (32 shown in FIG. 7) for the customer CS01. Yen / kWh) to calculate the power rate.

[Summary]
As described above, the collation unit 130 according to the present embodiment uses the power usage contract information CI, the generated power amount information GE acquired by the generated power amount information acquisition unit 110, and the use acquired by the used power amount information acquisition unit 120. Based on the power amount information UE, the amount of generated power and the amount of power used are collated for each type. Here, the generated power amount information GE acquired by the generated power amount information acquiring unit 110 indicates the current generated power amount at the timing when the verification unit 130 collates. Further, the used power amount information UE acquired by the used power amount information acquiring unit 120 indicates the current used power amount at the timing when the collating unit 130 collates. That is, the collation unit 130 of the present embodiment collates the generated power amount obtained in real time with the used power amount.

  In addition, a contract is made between the power supplier and the customer CS to supply power by limiting the type of the power plant PP. Here, if the type of electric power to be used, that is, the type of the power plant PP is limited, the supply and demand balance is likely to be lost compared to the case where the type of the power plant PP is not limited. When the supply-demand balance is disrupted while a specific type of power plant PP is supplying power, the customer CS can generate a power plant PP of a type other than the type of power plant PP (for example, power plant PP08) (for example, There is a case where power supply from the power plant PP07) must be received.

Since the collation unit 130 of the present embodiment collates the amount of generated power and the amount of power used in real time, a collation result RC that reflects the disruption of supply and demand balance in real time is obtained. Therefore, since the charge calculation unit 140 calculates the power charge based on the verification result RC of the verification unit 130, it is possible to calculate the power charge that reflects the disruption of the supply and demand balance in real time.
That is, according to the charge calculation device 10 of the present embodiment, it is possible to calculate a power charge that reflects the disruption of supply and demand balance in real time.
According to the charge calculation device 10 of the present embodiment, it is possible to calculate a charge according to the type of power supply when the power supply type is limited.

  In addition, the charge calculation device 10 according to the present embodiment performs step-by-step verification based on a contract stage in power amount verification. In other words, the fee calculation device 10, when the type of power limited by the first stage contract (for example, the power generated in “F village G river”) is insufficient, is the type limited by the second stage contract. The charge of the power (for example, the power generated in “a river in village F”) is calculated. As a result, the charge calculation device 10 causes the balance between supply and demand to be disrupted by limiting the type of power, and even if the customer CS is supplied with power from other power plants PP, Electricity charges can be calculated.

  Moreover, since the charge calculation apparatus 10 of this embodiment calculates an electric power charge for every kind of electric power, it can produce | generate the billing information BL which a consumer CS is easy to understand.
