  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing an example of the privilege information calculation system of the present invention. The privilege information calculation system of the present invention includes a facility usage status measurement device 10, an information storage server 20, and a privilege information calculation device 30. The privilege information calculation system can also be referred to as a privilege information determination system. The privilege information calculation device can also be referred to as a privilege information determination device.

  Here, the privilege information is information representing a privilege given to the electric power user depending on the usage state of the power generation facility or the power storage facility of the electric power user. As privilege information, a point is mentioned, for example. Points are also referred to as “loyalty points” or “rewards points”, but in the following description, they are simply referred to as points. Further, the privilege information may be a value other than points such as a monetary amount, but in the following description, a case where the privilege information is points will be described as an example. That is, the case where the privilege information calculation device 30 calculates points as privilege information will be described as an example.

  The equipment usage status measuring device 10 measures the usage status of power generation equipment and power storage equipment in the homes of power consumers. As examples of the power generation equipment, home power generation devices 45a and 45b described later can be given. Moreover, the below-mentioned storage battery 41 etc. are mentioned as an example of electrical storage equipment. In the following description, a case where the facility usage status measuring device 10 is realized by a HEMS (Home Energy Management System) will be described as an example. Hereinafter, the facility usage status measuring device 10 is referred to as HEMS10. Although one HEMS 10 is illustrated in FIG. 1, the HEMS 10 is provided for each home of a power consumer to whom points are given according to the present invention. In the following description, the description will be made by paying attention to the HEMS 10 of one electric power consumer, but other HEMS (not shown) operate in the same manner as the HEMS 10.

  The information storage server 20 stores the use status of the power generation facility and the power storage facility in the home of the power consumer measured by the HEMS 10.

  The privilege information calculation device 30 calculates points for the power consumer. The privilege information calculation unit 33 is connected to a point server 40 that manages points of a point service (loyalty program) used by electric power consumers. The privilege information calculation device 30 transmits the calculated points to the point server 40. Although one point server is illustrated in FIG. 1, the point server 40 is not limited to one. The power consumer designates in advance one point service from among various point services (for example, a convenience store point service, an airline point service, etc.) that he or she uses. And the privilege information calculation apparatus 30 transmits the point of an electric power consumer to the point server 40 corresponding to the point service previously designated by the electric power consumer. The point server 40 adds the points as points of the power consumer. In this invention, the privilege information calculation apparatus 30 calculates the point of the electric power consumer as a big value, so that an electric power consumer uses the electric power using a power generation equipment or an electrical storage equipment. Therefore, the more power users use the electric power using the power generation equipment and the power storage equipment, the more services they can receive with the point service they are using.

  In the present embodiment, an example will be described in which home power generators 45a and 45b and a storage battery 41 are provided in the home of a power consumer.

The home power generators 45a and 45b are home power generators that have a CO ₂ emission constant smaller than the carbon dioxide (CO ₂ ) emission constant (the emission constant in a time zone other than nighttime) when the electric power company supplies power. is there. Here, the emission constant is a constant for converting electric power into CO ₂ emission. By multiplying the electric power by the emission constant, the CO ₂ emission amount is obtained. Examples of the discharge constant is small household power generator CO ₂ than the discharge constant of the CO ₂ in the power company, there is a home power generator that generates electricity by renewable energy. Furthermore, a household solar power generation device can be given as an example of a home power generation device that generates power using renewable energy. Household solar power generation apparatus or the like, because does not generate CO _2, the discharge constant of the CO ₂ is zero. Hereinafter, it is assumed that the home power generation device 45a does not generate CO ₂ (that is, the CO ₂ emission constant is 0). Also, a home power generation device 45b has a CO ₂ generated during power generation, the discharge constant of the CO ₂ in the domestic power generation device 45b is assumed to be greater than 0. However, it is smaller than the CO ₂ emission constant of the electric power company. As an example of such an in-home power generation device, for example, a home fuel cell cogeneration system can be cited. The domestic power generation devices 45a and 45b supply the generated power to the power supply unit 11 of the HEMS 10.

  In this example, the case where the home power generators 45a and 45b are provided in the home of the power consumer will be described as an example, but only one of the home power generators 45a and 45b is in the home of the power consumer. It may be provided.

Further, in the present embodiment, it is assumed that the CO ₂ emission constant when the electric power company supplies electric power differs between nighttime and a time zone other than nighttime. It is assumed that the ratio of thermal power generation is low at night, and the emission constant of the electric power company at night is smaller than the emission constant of the electric power company at times other than night. Moreover, it can be said that the night is a time zone in which the power purchase price is relatively low.

  The storage battery 41 is a battery that can store electricity, and supplies power to the power supply unit 11 of the HEMS 10.

  The HEMS 10 includes a power supply unit 11, a power measurement unit 12, and an information transmission unit 13.

  The power supply unit 11 receives power supplied from an electric power company and supplies the power to devices in the home of the power consumer. The power supply unit 11 also receives supply power from the home power generation devices 45a and 45b. The power supply unit 11 preferentially supplies the power supplied from the home power generation devices 45a and 45b to the devices in the home of the power consumer. At each time point, the power supply unit 11 supplies power from the home power generators 45a and 45b when the power supplied from the home power generators 45a and 45b exceeds the power consumed by the devices in the home. The surplus power out of the power is stored in the storage battery 41. The power supply unit 11 may sell the remaining power stored in the storage battery 41 among the power supplied from the home power generation devices 45a and 45b to the power company. The power supply unit 11 also receives power supply from the storage battery 41 after storage, and supplies the power to household devices. However, in the present embodiment, it is assumed that the time zone in which the storage battery 41 supplies power to devices in the home is set to a time zone other than nighttime. In addition, it is assumed that the time corresponding to the night is predetermined.

  The power measuring unit 12 supplies power (hereinafter referred to as self-consumed power) supplied to devices in the home out of the power generated by the home power generation devices 45a and 45b within a predetermined period for each predetermined period. In addition, power stored in the storage battery 41 (hereinafter referred to as stored power) among the power generated by the home power generation devices 45a and 45b is measured. The power sold is not included in the self-consumption power because it does not correspond to the power supplied to the device in the home. Of the power generated by the home power generation devices 45a and 45b, the power once stored in the storage battery 41 is not included in the self-power consumption.

  Hereinafter, among the electric power generated by the home power generation device 45a, the power supplied to the home appliance is referred to as self-power consumption based on the home power generation device 45a. Of the power generated by the home power generation device 45b, the power supplied to the home appliance is referred to as self-consumption power based on the home power generation device 45b. Moreover, the electric power stored in the storage battery 41 among the electric power generated by the home power generation device 45a is referred to as stored power based on the home power generation device 45a. Of the power generated by the home power generation device 45b, the power stored in the storage battery 41 is referred to as stored power based on the home power generation device 45b. It can be said that these are values representing the usage status of the power generation facility and the power storage facility.

  The power supply unit 11 stores power in the storage battery 41 with power supplied from the power company. However, the time zone in which the power supply unit 11 stores power in the storage battery 41 with the power supplied from the power company is limited to nighttime. In addition, the time slot | zone when the electric power supply part 11 charges with respect to the storage battery 41 with the electric power supplied from the household electric power generation apparatus 45a, 45b may not be restricted to night. Further, as described above, it is assumed that the time zone in which the storage battery 41 supplies power to devices in the home is a time zone other than nighttime. The power that the power supply unit 11 stores in the storage battery 41 with the power supplied from the power company is referred to as night storage power. The power measuring unit 12 also measures the nighttime stored power within a predetermined period for each predetermined period. It can also be said that the nighttime stored power is also a value representing the usage status of the power generation facility and the storage facility.

  Hereinafter, the case where the predetermined period is one month will be described as an example.

  The information transmission unit 13 includes a self-power consumption based on the home power generation device 45a, a stored power based on the home power generation device 45a, and a self power consumption based on the home power generation device 45b for one month in the home of the power consumer. Then, each information of the stored power based on the home power generator 45b and the stored power at night is transmitted to the information storage server 20.

  The power measuring unit 12 and the information transmitting unit 13 are realized by, for example, a CPU (Central Processing Unit) of a computer that operates according to a program for facility usage status measuring apparatus. In this case, the CPU may read the program and operate as the power measurement unit 12 and the information transmission unit 13 according to the program.

  Further, the HEMS 10 displays the power consumption state of the power consumer on the display device (not shown) of the power consumer, or performs optimization control of the operation of each device in the home. Since this is not directly related to the present invention, its description is omitted.

  The information storage server 20 includes a power storage unit 21 and a control unit 22.

  The control unit 22 stores information received from the HEMS 10 in the power storage unit 21 or transmits information stored in the power storage unit 21 to the privilege information calculation device 30 in response to a request from the privilege information calculation device 30. To do.

  The power storage unit 21 includes, for each power consumer, a power consumer ID, self-power consumption based on the monthly power generation device 45a, self-power consumption based on the monthly power generation device 45b, This is a storage device that stores information on the stored power based on the monthly power generator 45a, the stored power based on the monthly power generator 45b, and the monthly stored power per month.

  FIG. 2 is an explanatory diagram schematically illustrating an example of information stored in the power storage unit 21. The power consumer ID is an ID (Identification) assigned to each power consumer. Moreover, the self-power consumption based on the domestic power generation device 45a for one month notified from the information transmission unit 13 of the HEMS 10 every month, the self-power consumption based on the home power generation device 45b for one month, Information on the stored power based on the home power generation device 45a, the stored power based on the home power generation device 45b for one month, and the stored power for one month at night is stored in the power storage unit 21 by the control unit 22.

  The privilege information calculation device 30 includes a privilege information calculation unit 33.

And the privilege information calculation part 33 is the self-power consumption based on the domestic power generation device 45a, the self-power consumption based on the home power generation device 45b, the stored power based on the home power generation device 45a, and the home power generation for each power consumer. Based on the stored power based on the device 45 b and the night-time stored power, a point of power consumers for one month is calculated and transmitted to the point server 40.

  The privilege information calculation part 33 is implement | achieved by CPU of the computer which operate | moves according to a privilege information calculation program, for example. In this case, the CPU may read the privilege information calculation program and operate as the privilege information calculation unit 33 according to the program. The privilege information calculation program may be stored in a computer-readable recording medium.

  Next, the process progress of this embodiment is demonstrated. FIG. 3 is a sequence diagram showing an example of processing progress of the privilege information calculation system of the present invention.

  The privilege information calculation system performs the following operation for each predetermined period.

  During one month, the power supply unit 11 of the HEMS 10 receives the supply power from the home power generation devices 45a and 45b, the supply power from the storage battery 41, and the supply power from the power company, Supply power to other devices. At this time, the power supply unit 11 preferentially supplies the power supplied from the home power generation devices 45a and 45b to the devices in the home. As described above, when the power supplied from the home power generators 45a and 45b exceeds the power consumed by the home appliances, the power supply unit 11 supplies power from the home power generators 45a and 45b. The remaining power is stored in the storage battery 41. The power supply unit 11 may sell the remaining power stored in the storage battery 41 among the power supplied from the home power generation devices 45a and 45b to the power company. The power supply unit 11 stores, in the storage battery 41, power that can be stored in the storage battery 41 among the power supplied from the power company at night.

  Then, the power measuring unit 12 includes self-power consumption based on the home power generation device 45a for one month, self-power consumption based on the home power generation device 45b for one month, and power storage based on the home power generation device 45a for one month. The power, the stored power based on the domestic power generation device 45b for one month, and the stored power for one month are measured (step S1).

  In some cases, the storage battery 41 is not provided in the home of the power consumer. In this case, the power measuring unit 12 sets the stored power based on the home power generation device 45a for each month, the stored power based on the home power generation device 45b for each month, and the stored power for the night of each month to zero.

In addition, there is a case where the home power generation device 45a (the home power generation device that does not generate CO _2. For example, the home solar power generation device) is not provided in the home of the power consumer. In that case, the power measurement unit 12 sets the self-power consumption based on the home power generation device 45a for each month and the stored power based on the home power generation device 45a for each month to zero.

In addition, there is a case where the home power generation device 45b (home power generation device with generation of CO _2. For example, home fuel cell cogeneration system) is not provided in the home of the power consumer. In that case, the power measuring unit 12 sets the self-power consumption based on the home power generation device 45b for each month and the stored power based on the home power generation device 45b for each month to zero.

  And the information transmission part 13 is the self-power consumption based on the home electric power generation apparatus 45a for one month which the electric power measurement part 12 measured at the end of a predetermined period (the end of the month in this example), the home for one month Information on the self-consumption power based on the power generation device 45b, the stored power based on the home power generation device 45a for one month, the stored power based on the home power generation device 45b for one month, and the night power storage power for one month Then, the information is transmitted to the information storage server 20 together with the power consumer ID (step S2).

  The control unit 22 includes self-power consumption based on the home power generation device 45a for one month, self-power consumption based on the home power generation device 45b for one month, stored power based on the home power generation device 45a for one month, Each information of the stored electricity based on the domestic power generation device 45b for one month, the nightly stored power for one month, and the power consumer ID are received from the information transmitting unit 13. Then, the control unit 22 self-power consumption based on the home power generation device 45a for the month, self-power consumption based on the home power generation device 45b for one month, and power storage based on the home power generation device 45a for one month. Each information of electric power, electric power stored based on the domestic power generation device 45b for one month, and electric power stored for one month at night is stored in the electric power storage unit 21 in association with the electric power consumer ID (step S3). .

  And the privilege information calculation part 33 of the privilege information calculation apparatus 30 is for every predetermined period (for example, every month beginning), the electric power user ID of each electric power user, and the domestic power generator for the predetermined period of the past. Information of the self-power consumption based on 45a, the self-power consumption based on the home power generation device 45b, the power storage power based on the home power generation device 45a, the power storage power based on the home power generation device 45b, and the night time power storage power from the information storage server 20 Obtain (step S4). In this example, the predetermined period closest to the past means the target period for the previous month. Specifically, the privilege information calculation unit 33 requests the information storage server 20 for each piece of information for the previous month. Upon receiving this request, the control unit 22 of the information storage server 20 reads the requested information from the power storage unit 21 and transmits it to the privilege information calculation device 30. And the privilege information calculation part 33 is the electric power user ID of each electric power user, the self-power consumption based on the domestic power generation device 45a last month, the self-power consumption based on the home power generation device 45b last month, the home of last month Each information of the stored power based on the internal power generation device 45a, the stored power based on the domestic power generation device 45b last month, and the last night's stored power is received from the information storage server 20.

  Next, the privilege information calculation unit 33 sets the point indicating the usage level of the power generation facility and the power storage facility last month for each power consumer, the self-power consumption based on the home power generation device 45a last month, and the home power generation last month. Calculations are made based on the self-consumption power based on the device 45b, the stored power based on the domestic power generation device 45a last month, the stored power based on the domestic power generation device 45b last month, and the night stored power last month (step S5).

The process of step S5 will be specifically described. The privilege information calculation unit 33 selects one power consumer ID from the power consumer IDs of each power consumer received in step S4. Here, let Z ₁ [kWh] be the self-power consumption based on the domestic power generation device 45a last month corresponding to the selected power consumer ID. Also, let Z ₂ [kWh] be the stored power based on the domestic power generation device 45a last month corresponding to the selected power consumer ID. Further, let W ₁ [kWh] be the self-power consumption based on the domestic power generation device 45b last month corresponding to the selected power consumer ID. The stored power based on the domestic power generation device 45b last month corresponding to the selected power consumer ID is defined as W ₂ [kWh]. Further, the stored power of last month corresponding to the selected power consumer ID is V [kWh]. The privilege information calculation part 33 calculates the point (it is set as P) of the electric power consumer which the selected electric power consumer ID shows by calculating the formula (1) shown below.

P = ((Z ₁ + Z ₂ ) * discharge constant A
+ (W ₁ + W ₂ ) * (discharge constant A−discharge constant B)
+ V * (discharge constant A−discharge constant C))
* Point conversion constant
Formula (1)

  However, when the calculation result of Expression (1) is negative, the privilege information calculation unit 33 sets P = 0.

The emission constant A is an emission constant of CO ₂ in a time zone other than nighttime of the electric power company. The emission constant B is a CO ₂ emission constant of the domestic power generation device 45b. The emission constant C is a CO ₂ emission constant at night of the electric power company. The discharge constants A and C may be determined individually for each electric power company. Also, the discharge constant B may be determined individually according to the home power generation device 45b. For example, the discharge constants A, B, and C are stored in the power storage unit 21 for each power consumer ID, and the privilege information calculation unit 33 performs the discharge constants A, B, and C for each power consumer ID in step S4. C may be acquired from the information storage server 20.

The point conversion constant is a constant for converting the CO ₂ emission reduced by using the power generation facility and the power storage facility into points. Points are determined by multiplying the reduced CO ₂ emissions by a point conversion constant. The point conversion constant may be different for each point server 40. In that case, for example, the point conversion constant corresponding to the point service designated in advance by the power consumer is stored in the power storage unit 21 for each power consumer ID, and the privilege information calculation unit 33 performs power consumption in step S4. A point conversion constant for each consumer ID may be acquired from the information storage server 20.

(Z ₁ + Z ₂ ) in the formula (1) is electric power obtained by the domestic power generation device 45a without generating CO ₂ . Therefore, (Z ₁ + Z ₂ ) * emission constant A represents the CO ₂ emission amount reduced by utilizing the domestic power generation device 45a and the storage battery 41.

Further, (W ₁ + W ₂ ) is electric power obtained by the home power generation device 45b. Therefore, (W ₁ + W ₂ ) * (emission constant A−emission constant B) represents the CO ₂ emission amount reduced by utilizing the home power generation device 45b and the storage battery 41.

Further, V is electric power generated at night by an electric power company and stored in the storage battery 41. At night, the rate of thermal power generation is lower than in non-night time periods, and the power generated at night can be stored and used in non-night time periods to reduce CO ₂ emissions. Therefore, V * (discharge constant A−discharge constant C) represents the CO ₂ emission amount reduced by using the electric power generated at night and stored in the storage battery 41.

Equation (1) means that points are calculated by multiplying the sum of CO ₂ reduction amounts by a point conversion constant. Value of about Z ₁ home power generation device 45a is utilized is increased, as the domestic power generation device 45b is utilized, the value of W ₁ is increased. Further, as the storage battery 41 is _utilized, the value of Z _{2, W} 2, V increases. Therefore, the greater the extent to which the home power generation devices 45a and 45b and the storage battery 41 are used, the greater the amount of CO ₂ emission reduction. As a result, the point calculated by equation (1) also increases.

  If the privilege information calculation unit 33 calculates a point for the selected power consumer ID, the privilege information calculation unit 33 selects an unselected power consumer ID and similarly calculates the point. The privilege information calculation unit 33 repeats this process until there is no unselected power consumer ID, and when there is no unselected power consumer ID, the process ends step S5.

  After step S5, the privilege information calculation unit 33 transmits, for each power consumer ID, the point calculated in step S5 with respect to the power consumer ID and the power consumer ID to the point server 40 (step S6). . In step S6, the point server 40 serving as a point transmission destination is a point server corresponding to a point service designated in advance by the power consumer represented by the power consumer ID. For example, when a certain power consumer designates a point service of a certain convenience store, the privilege information calculation unit 33 uses the power consumer ID and points of the power consumer as the point service of the convenience store. To the point server that manages the points.

  The point server 40 accumulates points each time a power user purchases a product or receives a service from an administrator of the point server 40 (for example, a convenience store or an airline). . When the point server 40 receives the power consumer ID and the points transmitted by the privilege information calculation unit 33 in step S6, the point information 40 is added to the point of the power customer indicated by the power customer ID. Add the points received from. The power consumer can receive various services (for example, discounts on product prices) from the manager of the point server 40 using the points stored in the point server 40.

  In the above example, the case where step S4 is executed at the beginning of the month and step S2 is executed at the end of the month is shown. However, the timing for executing the processes of steps S2, S4, etc. within the predetermined period is as described above. It is not limited to examples.

  According to the present embodiment, not only when a product is purchased from a manager of the point server 40 or a service is provided, but also when the power generation facility or the storage facility is utilized, the point server 40 accumulates the product. Points increase. And the point which is added becomes large, so that the use degree of a power generation facility or an electrical storage facility is large, and it can receive more services from the administrator of the point server 40. Therefore, it is possible to give an incentive to use power generation facilities and power storage facilities to power consumers.

  Specifically, the value of the point calculated in step S5 increases as the household power generation devices 45a and 45b and the storage battery 41 are used more. Therefore, incentives can be given to power consumers according to the extent to which the domestic power generation devices 45a and 45b and the storage battery 41 are utilized. For example, an incentive to utilize the domestic power generation devices 45a, 45b and the storage battery 41 is given to power users who did not own the home power generation devices 45a, 45b and the storage battery 41, and the diffusion of these facilities is promoted. Can reduce the power shortage.

  Further, in the above example, the calculated point increases as the nighttime stored power V increases. Therefore, incentives that contribute to power generation suppression at the electric power company in a time zone other than nighttime can also be given to electric power consumers.

Moreover, in this embodiment, since the point according to the extent to which the power generation equipment and the power storage equipment is used is calculated every predetermined period, the incentive to use the power generation equipment and the power storage equipment is continuously given to the power consumer. Can be given. As a result, the present invention can contribute to the realization of a low-carbon society (a society with low CO ₂ emissions).

Also, bonus information calculation unit 33, by multiplying the point conversion constant CO ₂ emissions have been reduced by utilization of power generation equipment and storage equipment, calculates a point (see Equation (1)). Then, the manager of the point server 40 provides more services to the power consumer in accordance with the added points. Therefore, in the CO ₂ emission trading, it can be considered that the manager of the point server 40 is reducing the CO ₂ emission by the point calculated by the privilege information calculation unit 33.

  In addition, the privilege information calculation part 33 may calculate a point by calculation of the following formula | equation (2), without using the discharge | emission constant and point conversion constant shown to Formula (1).

P = ((Z ₁ + Z ₂ ) + (W ₁ + W ₂ ) + V) * point conversion constant
Formula (2)

That is, the points may be calculated directly without obtaining the CO ₂ reduction amount. The point conversion constant in equation (2) is a constant for converting electric power directly into points.

In this embodiment, when the privilege information calculation unit 33 calculates the points of each power consumer, the stored power is uniformly used regardless of whether each power consumer owns the storage battery 41 or not. Instead, the points may be calculated. In this case, Z ₂ = W ₂ = 0 in Formula (1) and Formula (2).

  In this case, the power measurement unit 12 does not have to measure the stored power based on the domestic power generation device 45a for one month and the stored power based on the domestic power generation device 45b for one month in step S1. As a result, the information transmission unit 13 does not transmit the information on the stored power based on the domestic power generation device 45a for one month and the stored power based on the domestic power generation device 45b for one month to the information storage server 20 in step S2. It's okay. Furthermore, the control unit 22 does not have to store in the power storage unit 21 the information on the stored power based on the domestic power generation device 45a for one month and the stored power based on the domestic power generation device 45b for one month in step S3. . Further, the privilege information calculation unit 33 does not acquire the information on the stored power based on the home power generation device 45a for one month and the stored power based on the home power generation device 45b for one month from the information storage server 20 in step S4. It's okay. Even in this case, it is possible to give an incentive to the power consumer to utilize the domestic power generation devices 45a and 45b.

  Moreover, the privilege information calculation part 33 may calculate a point, without using night electricity storage power uniformly irrespective of whether each electric power user owns the storage battery 41 or not. In this case, V = 0 may be set in Expression (1) or Expression (2). Further, in this case, it is not necessary to perform measurement of nighttime stored power, transmission of nighttime stored power to the information storage server 20, and the like. In this case, the time zone during which the storage battery 41 supplies power may not be particularly limited. Even in this case, it is possible to give an incentive to the power consumer to utilize the domestic power generation devices 45a and 45b.

Further, the privilege information calculation unit 33 calculates points without using self-power consumption uniformly regardless of whether or not each individual electric power consumer owns the home power generation device 45a or the home power generation device 45b. May be. In this case, Z ₁ = W ₁ = 0 in Formula (1) or Formula (2). In this case, the self power consumption based on the home power generation device 45a, the self power consumption based on the home power generation device 45b, transmission to the information storage server 20, and the like do not have to be performed. Even in this case, an incentive to utilize the storage battery 41 can be given to a power consumer.

  Moreover, in said embodiment, a privilege information calculation system calculates a point using the information of the electric power generation amount for the predetermined period (for example, one month) in the domestic power generation device 45a or the home power generation device 45b. Also good. For example, the power generation amount for one month in the home power generation device 45a is T [kWh]. Further, the power generation amount for one month of the home power generation device 45b is U [kWh]. In this case, the privilege information calculation part 33 of the privilege information calculation apparatus 30 should just calculate the point P by calculation of Formula (3) shown below.

P = (T * emission constant A
+ U * (Emission constant A-Emission constant B)
+ V * (discharge constant A−discharge constant C))
* Point conversion constant
Formula (3)

  In this case, the power measurement unit 12 of the HEMS 10 measures the power generation amount for one month of the home power generation device 45a and the power generation amount for one month of the home power generation device 45b. In this case, power is not sold from the power consumer to the power company. The HEMS 10 transmits information on the power generation amount for one month of the home power generation device 45a and information on the power generation amount for one month of the home power generation device 45b to the information storage server 20, and the information storage server 20 sends the information. The mode of storing may be the same as in steps S2 and S3. Further, the privilege information calculation unit 33 acquires information on the amount of power generation for one month of the home power generation device 45a and information on the amount of power generation for one month of the home power generation device 45b from the information storage server 20, It may be the same as S4. Alternatively, the points may be calculated using one of the information on the amount of power generation for one month of the home power generation device 45a and the information on the amount of power generation for one month of the home power generation device 45b. If the former information is used and the latter information is not used, U = 0 may be set uniformly. When the latter information is used and the former information is not used, T = 0 may be set uniformly. Further, as already described, the points may be calculated without using the nighttime stored power uniformly.

  Also in this example, as the power generation amount of the home power generation device 45a and the power generation amount of the home power generation device 45b increase, more points are given to the power consumer. Therefore, an incentive to utilize the domestic power generation device 45a and the home power generation device 45b can be given to the power consumer.

Next, a modification of the above embodiment will be described.
In the above-described embodiment, the longer the period during which the power consumer receives the points calculated by the privilege information calculation unit 33, the more the privilege information calculation unit 33 calculates the points for the consumer. May be. That is, the longer the period during which the power consumer receives the points calculated by the privilege information calculation unit 33, the privilege information calculation unit 33 further increases the points in addition to the points calculated in the above embodiment. You may add.

  In addition, when the power consumer owns equipment such as the domestic power generation devices 45a and 45b and the storage battery 41, the privilege information calculation unit 33 may calculate many points for the consumer. . That is, when the power consumer owns equipment such as the domestic power generation devices 45a and 45b and the storage battery 41, the privilege information calculation unit 33 further adds those points in addition to the points calculated in the above embodiment. Points depending on the equipment may be added. For example, the privilege information calculation unit 33 has a power consumer who owns the home power generators 45a and 45b than a power consumer who owns only one of the home power generators 45a and 45b. Even add many points.

  Moreover, in said embodiment, the privilege information calculation part 33 demonstrated as an example the case where the point of the power consumer was transmitted to the point server 40 corresponding to the point service previously designated by the power consumer. . Even if the privilege information calculation unit 33 transmits information recommending point addition to a specific point service among the point services already received by the power consumer to the terminal (not shown) of the power consumer. Good. And the privilege information calculation part 33 transmits the point of the electric power consumer to the point server 40 corresponding to the recommended point service, when the information to the effect of receiving the recommendation is received from the terminal of the electric power consumer. Also good.

  Moreover, in said embodiment, the case where the electric power memory | storage part 21 of the information storage server 20 memorize | stores the information of various electric power received from electric power consumer ID and HEMS10 was shown. Each HEMS 10 may be configured to store a power consumer ID of a power consumer who owns the HEMS 10 and various kinds of power information. FIG. 4 is a block diagram illustrating a configuration example in the case where the HEMS 10 stores a power consumer ID and various types of power information. 4, elements similar to those shown in FIG. 1 are denoted by the same reference numerals as those in FIG. 1, and description thereof is omitted. In the configuration illustrated in FIG. 4, the HEMS 10 includes a power storage unit 15. The power storage unit 15 stores one piece of information of a power consumer among the information shown in FIG. That is, the power storage unit 15 includes the power consumer ID of the power consumer who owns the HEMS 10, the self-power consumption based on the domestic power generation device 45a for one month, and the self power consumption based on the domestic power generation device 45b for one month. Information on power consumption, stored power based on the domestic power generation device 45a for one month, stored power based on the domestic power generation device 45b for one month, and stored power for one month is stored. In place of step S2 (see FIG. 3), the power measuring unit 12 uses self-power consumption based on the domestic power generation device 45a for one month, self-power consumption based on the domestic power generation device 45b for one month, and for one month. The power storage unit 15 may store information on the stored power based on the home power generator 45a, the stored power based on the home power generator 45b for one month, and the night stored power for one month. Each HEMS 10 of each electric power consumer stores information on various electric powers as described above. Then, in step S4, the privilege information calculation unit 33, instead of acquiring information from the information storage server 20, from each HEMS 10 to the power generator ID 45a and the domestic power generation device 45a for a predetermined period in the past. Information on self-consumption power based on power consumption, self-power consumption based on home power generation device 45b, power storage power based on home power generation device 45a, power storage power based on home power generation device 45b, and night time power storage power may be acquired. The other points are the same as in the above-described embodiment.

  Next, the main part of the present invention will be described. FIG. 5 is a block diagram illustrating an example of a main part of the privilege information determination device of the present invention. The privilege information determination device of the present invention includes information acquisition means 81 and privilege information determination means 82.

  The information acquisition means 81 (for example, privilege information calculation part 33) acquires the information of the electric power generation amount in the electric power user's electric power generation equipment.

  The privilege information determination means 82 (for example, privilege information calculation part 33) determines the privilege information of an electric power user based on the information of the electric power generation amount.

  With such privilege information determination device, an incentive to use the power generation facility and the power storage facility can be given to the power consumer.

  Moreover, the information acquisition means 81 may acquire the information on the amount of power stored in the power storage facility of the power consumer. And the privilege information determination means 82 may determine the privilege information of an electric power user based on the information of the electrical storage amount.

  Moreover, the information acquisition means 81 may acquire the information of the power consumption (for example, self-power consumption) generated by the power generation facility of the power consumer and consumed by the power consumer. And the privilege information determination means 82 may determine the privilege information of an electric power user based on the information of the power consumption.

  Moreover, the information acquisition means 81 may acquire the information of the 1st electrical storage electric power produced | generated by the electric power user's electric power generation equipment, and stored in the storage battery. And the privilege information determination means 82 may determine the privilege information of an electric power user based on the information of the 1st stored electric power.

  Moreover, the information acquisition means 81 acquires the information of the 2nd electrical storage power (for example, night electrical storage power) stored in the storage battery of the electric power consumer with the electric power supplied in the time zone when the power purchase price is relatively low May be. And the privilege information determination means 82 may determine the privilege information of an electric power user based on the information of the 2nd stored electric power.

  Further, the information acquisition unit 81 may acquire information on the power generation type of power, and the privilege information determination unit 82 may determine the privilege information of the power consumer based on the information on the power generation type. In this case, an incentive to use power according to the type of power generation can be given to the power consumer.

  FIG. 6 is a block diagram showing a main part of the privilege information determination system of the present invention. The privilege information determination system of the present invention includes power measurement means 83 and privilege information determination means 82. The privilege information determining means 82 is the same as the privilege information determining means 82 shown in FIG.

  The power measuring unit 83 (for example, the power measuring unit 12) measures information on the amount of power generated in the power generation facility of the power consumer.

  With such privilege information determination system, it is possible to give an incentive to the power consumer to use the power generation facility and the power storage facility.

  In the above-described embodiment, the case where the home is used as the point calculation unit of the power consumer is shown. If management is possible for each unit, a point calculation unit may be condominium, factory, building, company, or the like. Moreover, although the case where HEMS10 was provided for every household was shown in said embodiment, you may provide HEMS10 according to the unit of the electric power user to which not only a household but a point is provided.

  Further, in this case, the power storage unit 21, for each point calculation unit of the power consumer, self-power consumption based on the monthly power generator, stored power based on the monthly power generator, and What is necessary is just to memorize | store the nighttime electrical power stored every month.

  Moreover, in said embodiment, the electric power generated from an in-home power generation device was mentioned as an example of the electric power measured for point calculation. The electric power measured for calculating the points may be electric power generated by an electric power company, or electric power generated in another home, factory, or building.

  The present invention can be applied not only to the use of power generation facilities and power storage facilities, but also to the case where points are added according to the type of power generation such as solar power generation or wind power generation. In this case, electric power users can further maintain incentives for realizing a low-carbon society.

Further, in the above-described embodiment, the case where the time zone in which the storage battery supplies power to devices in the home is a time zone other than the night has been described as an example. When storing electricity of a power generation type with less CO ₂ emissions, such as solar power generation, wind power generation, hydropower generation, etc., in a power storage facility and using that power during non-night time, the storage battery is used as a device in the home. The time zone for supplying power may be at night.

  In addition, in consideration of the incentives of power users who purchase solar power, wind power, hydropower, etc., supplied by electric power companies, etc., even if the unit price is somewhat high, purchase from electric power companies or other companies Even the power stored in the power storage facility may be subject to point calculation according to the acquisition route and the power generation type.

  Moreover, in said embodiment, the time which the electric power supply part 11 stores with respect to a storage battery with the electric power supplied from the electric power company was taken as nighttime. Depending on the power generation type of the power supplied from the power company, when there is less demand than supply and surplus power is generated, the power may be stored in the storage battery in a time zone other than at night. For example, when the electric power supplied from the electric power company is electric power generated by solar power generation and surplus electric power is generated, the electric power may be stored in the storage battery in a time zone other than at night.
