  In the present embodiment, it is assumed that an upper limit of the amount of power that can be consumed in each time zone is set as a whole at a plurality of bases, and no more can be used. In the present embodiment, the plurality of bases are homes in a region where power consumption is restricted, or homes that subscribe to a power consumption management system.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

  FIG. 1 is a block diagram showing a configuration example of a power consumption management system according to an embodiment of the present invention. The power consumption management system 100 includes a server 2 and a plurality of terminals 1 connected to a network. The terminal 1 is installed in each home. The user makes a power reservation by accessing the server 2 using the terminal 1.

  FIG. 2 is a diagram illustrating a functional configuration example of the terminal and the server according to the embodiment. The terminal 1 includes a reception unit 11, a display unit 12, an input unit 13, a storage unit 14, a power consumption amount acquisition unit 15, and a transmission unit 16.

  The receiving unit 11 receives reservation screen information indicating a reservation screen for the user to reserve power from the server 2. In addition, the receiving unit 11 receives from the server 2 reservation impossible information indicating that the power input by the user cannot be reserved. Further, the receiving unit 11 has reservation fee information indicating a reservation fee charged when a reservation indicated by the reservation information is made, and a usage fee charged for power consumed when the reservation indicated by the reservation information is executed. The usage fee information indicating is received from the server 2. The receiving unit 11 sends the received reservation screen information, reservation impossible information, reservation fee information, and usage fee information to the display unit 12. The receiving unit 11 sends the received reservation impossible information to the storage unit 14.

  The display unit 12 displays a reservation screen based on the reservation screen information. Further, the display unit 12 displays on the reservation screen that the power input by the user cannot be reserved based on the reservation impossible information. Furthermore, the display unit 12 displays the reservation fee and the usage fee for the power reservation input by the user on the reservation screen based on the reservation fee information and the usage fee information.

  The input unit 13 accepts a power reservation from the user. The user inputs a power reservation on the reservation screen displayed on the display unit 12 via the input unit 13. The input unit 13 generates reservation information by associating a user ID for identifying the terminal 1 with information indicating the input reservation, and sends the reservation information to the transmission unit 16. Further, the input unit 13 sends the generated reservation information to the storage unit 14.

  The storage unit 14 stores the reservation information received from the input unit 13. Further, when the storage unit 14 receives the reservation impossible information from the receiving unit 11, the storage unit 14 deletes the corresponding reservation information. Therefore, the storage unit 14 stores only reservation information that can be reserved.

  The power consumption amount acquisition unit 15 acquires power consumption amount information indicating the power consumption amount in the home where the terminal 1 is installed during the reserved time period of the reservation information stored in the storage unit 14. For example, a watt hour meter is provided for each power source (outlet) and electrical device, and the power consumption amount acquisition unit 15 periodically acquires the power consumption amount from each watt hour meter, and associates the acquired date with the user ID. To generate power consumption information. The power consumption amount acquisition unit 15 sends the acquired power consumption amount information to the transmission unit 16.

  The transmission unit 16 transmits the reservation information to the server 2. Further, the transmission unit 16 transmits the power consumption information to the server 2.

  The server 2 includes a transmission unit 21, a reception unit 22, a management unit 23, and a storage unit 24.

  The transmission unit 21 transmits the reservation screen information stored in the storage unit 24 to the terminal 1. The transmission unit 21 transmits the reservation impossible information to the terminal 1. The transmission unit 21 transmits reservation fee information and usage fee information to the terminal 1.

  The receiving unit 22 receives reservation information from the terminal 1. The receiving unit 22 receives power consumption information from the terminal 1. The receiving unit 22 sends the received reservation information and power consumption information to the management unit 23.

  The management unit 23 refers to the reservation management table in which reserved reservation information stored in the storage unit 24 is registered, and determines whether or not the reservation indicated by the reservation information received from the reception unit 22 is possible. When it is determined that the reservation is possible, the management unit 23 registers the reservation information in the reservation management table. Details of the method for determining whether reservation is possible and the method for registering reservation information will be described later.

  If the management unit 23 determines that the reservation is possible, the management unit 23 calculates a reservation fee and a use fee of the reservation indicated by the reservation information. Details of the calculation method of the reservation fee and the usage fee will be described later. The management unit 23 causes the transmission unit 21 to transmit reservation fee information indicating the calculated reservation fee and usage fee information indicating the usage fee. On the other hand, when it is determined that the reservation is impossible, the management unit 23 causes the transmission unit 21 to transmit the reservation impossible information.

  Each time the management unit 23 receives the power consumption information from the reception unit 22, the management unit 23 calculates the accumulated power consumption by adding the power consumption indicated by the power consumption information, and stores it in the reservation management table stored in the storage unit 24. Let When the reserved time period ends, the management unit 23 determines whether the accumulated power consumption exceeds the reserved amount based on the reservation management table. When it is determined that the reserved amount has been exceeded, the management unit 23 calculates the excess power amount exceeding the reserved amount, and stores it in the reservation management table stored in the storage unit 24. On the other hand, if it is determined that the reserved amount is not exceeded, the management unit 23 determines whether the accumulated power consumption is insufficient for the reserved amount based on the reservation management table. When it is determined that the reserved amount is insufficient, the management unit 23 calculates the unused power amount that is insufficient for the reserved amount, and stores it in the reservation management table stored in the storage unit 24.

  When the management unit 23 determines that the reserved amount is exceeded, the management unit 23 may transmit the calculated excess power amount or excess information indicating that the power consumption amount exceeds the reserved amount to the terminal 1. In this case, the display unit 12 of the terminal 1 displays a screen indicating that the excess power amount or the power consumption amount exceeds the reserved amount based on the excess information received by the reception unit 11. Thereby, the user can know that the amount of power consumption has exceeded the reserved amount, and can expect a reduction in the amount of power consumption.

  Further, the terminal 1 may include a power source control unit that controls the power supply (outlet) or the power supply of the electric device. When the receiving unit 11 receives the excess information, the power supply control unit shuts off the power supply (outlet) or electric power supply corresponding to the excess information. Thereby, when the power consumption exceeds the reserved amount, the increase in the power consumption can be forcibly stopped. That is, power can be consumed as reserved.

  When the reserved time period ends, the management unit 23 charges the user of the terminal 1 based on the reservation management table stored in the storage unit 24. At this time, a reservation fee and a usage fee are charged for the power consumption for the reservation. Regarding the excess power amount, in addition to the usage fee, an amount larger than the reservation fee (for example, twice the reservation fee) is charged. That is, a penalty is imposed when the power consumption exceeds the reserved amount. Thereby, it can be expected that the user performs the power consumption activity as scheduled. For unused electric energy, only the reservation fee is charged. In addition, a user who has not reserved power can use power only with a usage fee, but cannot use power when the upper limit of the amount of power that can be consumed in the time period is exceeded. Alternatively, when the upper limit of the amount of power that can be consumed during the time period is exceeded, a usage fee that is higher than the reservation fee plus the usage fee when making a reservation is charged. As a result, the user can reserve only the necessary amount of electric power, and can expect other power consumption to be suppressed as much as possible. Therefore, the power consumption behavior of the user at each base is further suppressed.

  The charging method may use a method of prompting payment by notifying the user of the fee, such as calculating a fee based on the reservation management table and transmitting an email indicating the fee to the terminal 1, You may memorize | store in the memory | storage part 24 and use systems, such as automatic withdrawals, such as a credit card and a financial institution. Further, only the fee exceeding the usage fee, such as a reservation fee or penalty fee, may be charged, and the usage fee may be collected by the electric power company.

  The storage unit 24 stores a reservation management table. In addition, the storage unit 24 stores other information necessary for processing of the terminal 1 such as reservation screen information.

  FIG. 3 is a diagram illustrating an example of a reservation screen according to the embodiment. The example of FIG. 3 is a reservation screen for reserving 2011/08/01 power, which is displayed on the display unit 12 of the terminal 1 whose user ID is “001”. The user makes a power reservation on an hourly basis for each electrical device on the reservation screen. In the example of FIG. 3, the user has input a reservation for using “Living Air Conditioner” at a set temperature “26 ° C.” from 12:00 to 17:00. At this time, a reservation fee of 5 yen and a usage fee of 100 yen are displayed for this reservation. In addition, the user inputs a reservation for using “bedroom air conditioner” from 00:00 to 08:00 at a set temperature “28 ° C.”. At this time, a reservation fee of 4 yen and a usage fee of 120 yen are displayed for this reservation. Further, the user inputs a reservation for using the “washing machine” from 13:00 to 14:00 on the “washing course”. At this time, a reservation fee of 1 yen and a usage fee of 50 yen are displayed for making this reservation. Here, various settings can be input for an electric device with different power consumption settings, but it is also possible to input only the time zone used for each electric device.

  And if the user tries to make a reservation to use “living lighting” from 18:00 to 23:00, the upper limit of the amount of power that can be consumed in the input time zone will be exceeded. Message cannot be reserved. "

  The power reservation is not limited to the time unit reservation for each electrical device as shown in FIG. 3, but may be reserved for each power source or for each area divided in the home. Also good. Alternatively, reservations may be made on a time basis for each home.

  FIG. 4 is a diagram illustrating an example of a reservation management table according to the embodiment. In the example of FIG. 4, the reservation management table includes a “user ID” that identifies the terminal 1, a “use date” that is a date for using reserved power, and a “use time zone” that is a time slot for which use is reserved. “Reserved power amount” (reserved power amount per hour in parentheses) that is the reserved power amount, and “Cumulative power consumption amount” that is the power amount accumulated from the start of the usage time zone to the present ”,“ Excessive power amount ”that is the amount of power that exceeds the reserved power amount, and“ unused power amount ”that is the amount of power that is insufficient for the reserved power amount. A set of “user ID”, “use date”, “use time zone”, and “reserved power amount” is hereinafter referred to as an entry. Each time the management unit 23 receives reservation information from the reception unit 22, the management unit 23 determines whether the reservation is possible. If the reservation is possible, the management unit 23 registers an entry corresponding to the reservation information in the reservation management table.

  A process in which the management unit 23 registers reservation information in the reservation management table will be described with reference to FIGS. 3 and 4. As shown in FIG. 3, in the terminal 1 whose “user ID” is 0001, reservation information 1 {use date “2011/08/01”, electrical device “living air conditioner (temperature / 26 ° C.)”, use time zone “12: "00 to 17:00"}, reservation information 2 {electric equipment "bedroom air conditioner (temperature: 28 ° C)", use time zone "00:00 to 08:00"}, reservation information 3 {electric equipment "washing machine" (Washing course) ”, use time zone“ 13: 0 to 14:00 ”} and reservation information 4 {electric equipment“ living lighting ”, use time zone“ 18: 0 to 23:00 ”} are input. Suppose. The transmission unit 16 of the terminal 1 transmits the reservation information to the server 2 every time it is input. The storage unit 14 of the terminal 1 stores reservation information 1 to 4.

  The receiving unit 22 of the server 2 sequentially receives the reservation information and sends it to the management unit 23. Each time the management unit 23 receives the reservation information, the management unit 23 calculates a power consumption amount that is assumed when the electric device is used in a usage time period included in the reservation information as a reservation power amount. Specifically, the storage unit 24 stores electrical device information indicating the power consumption per hour assumed when each electrical device is used, and the management unit 23 refers to the electrical device information, The reservation power amount of the reservation information is calculated. For example, the power consumption amount per hour assumed when the electric device “living air conditioner” of the reservation information 1 is operated from 12:00 to 17:00 at a set temperature of 26 ° C. is 250 Wh. Is 250 (Wh) × 5 (hours) = 1250 (Wh).

  When the user reserves power in units of time for each power source, the reserved power amount is the power amount reserved by the user. The same applies to the case where power is reserved in units of time for each area divided in the home, and the case where power is reserved in units of time for each home.

  Here, a method for determining whether or not reservation information can be reserved will be described. When the management unit 23 receives the reservation information from the reception unit 22, the management unit 23 refers to the reservation management table stored in the storage unit 24 and extracts an entry in which the reservation information matches “user ID” and “use date”. Of the entries having the same “user ID” and “use date”, the entries are further narrowed down to entries having a partially or completely identical “use time zone”. Then, the management unit 23 obtains a partial or complete value obtained by adding the reserved power amount per hour of the reservation information calculated by the management unit 23 to the total value of the reserved power amount per hour of the narrowed entries. It is determined whether or not the upper limit value of the power consumption amount in the matching time zone is exceeded. When the upper limit value of the power consumption amount is exceeded, the management unit 23 determines that reservation is not possible for the reservation information. When the upper limit value of the power consumption amount is not exceeded, the management unit 23 determines that reservation is possible for the reservation information.

  The upper limit value of the power consumption amount is stored in the storage unit 24 in association with the date and / or time zone (for example, every hour). The upper limit value of the power consumption amount may be stored in advance in the storage unit 24, or may be acquired from the outside. The upper limit value of the consumable power amount is, for example, a request from a local government in a target area or a request from an electric power company. Or you may determine the upper limit of the power consumption amount between users. Moreover, the upper limit value of the consumable power amount is not actually the maximum value of the consumable power amount. That is, the amount of power is left in preparation for the case where the user consumes power exceeding the reserved amount, or when power is suddenly needed such as in an emergency.

  In the example of FIG. 3, the reservation information 1 to 3 can be reserved. For example, if the management unit 23 determines that the reservation information 1 can be reserved, as shown in FIG. 4, the “user ID” is 0001, the “use date” is 2011/08/01, and the “use time zone” is 12: 00 to 17:00, an entry having “reserved power amount (per hour)” of 1250 Wh (250 Wh) is registered in the reservation management table. Similarly, for the reservation information 2 and 3, entries are registered in the reservation management table.

  When the management unit 23 determines that the reservation information 1 to 3 can be reserved, the management unit 23 calculates each reservation fee and usage fee. Specifically, the storage unit 24 stores a reservation / use fee table in which a reservation fee and a use fee are associated with a date and a time zone, and the management unit 23 refers to the reservation / use fee table to make reservation information. 1 to 3 reservation fees and usage fees are calculated. The management unit 23 causes the transmission unit 21 to transmit reservation fee information indicating the calculated reservation information 1 to 3 and usage fee information indicating the usage fee. When receiving the reservation fee information and the usage fee information, the receiving unit 11 of the terminal 1 sends the reservation fee information and the usage fee information to the display unit 12. Based on the reservation fee information and the usage fee information, the display unit 12 displays the amount of the reservation fee and the usage fee respectively in the column of the reservation fee and the usage fee in the reservation information 1 to 3 on the reservation screen as shown in FIG. indicate.

  If the reservation information 1 to 3 determines that the reservation information can be reserved, the management unit 23 generates reservable information indicating that the reservation information 1 to 3 can be reserved, and causes the transmission unit 21 to transmit it. Also good. When receiving the reservable information, the receiving unit 11 of the terminal 1 sends it to the display unit 12. In this case, the display unit 12 changes a message, a symbol, a symbol, a color change, a character change, or the like indicating that a reservation is possible at the input location of the reservation information 1 to 3 on the reservation screen based on the reservation available information. Is displayed. The management unit 23 may cause the transmission unit 21 to transmit the reservable information, the reservation fee information, and the usage fee information together. In this case, the display unit 12 displays both a message indicating that a reservation is possible, a reservation fee, and a usage fee.

  In the present embodiment, when the management unit 23 determines that the reservation is possible, the management unit 23 registers the reservation information in the reservation management table. However, the present invention is not limited to this, and if the management unit 23 determines that the reservation is possible, the management unit 23 may calculate each reservation fee and usage fee, and first cause the transmission unit 21 to transmit the reservation fee information and the usage fee information. When receiving the reservation fee information and the usage fee information, the receiving unit 11 of the terminal 1 sends the reservation fee information and the usage fee information to the display unit 12. Based on the reservation fee information and the usage fee information, the display unit 12 displays the amount of the reservation fee and the usage fee respectively in the column of the reservation fee and the usage fee of the corresponding reservation information on the reservation screen as shown in FIG. To do.

  The user sees the displayed reservation fee and usage fee and inputs reservation determination information indicating that the reservation has been determined to the input unit 13 when actually making a reservation. The input unit 13 sends the input reservation determination information to the transmission unit 16. The transmission unit 16 transmits reservation determination information to the server 2. The reception unit 22 of the server 2 sends the received reservation determination information to the management unit 23. Upon receiving the reservation determination information, the management unit 23 registers the reservation information corresponding to the reservation determination information in the reservation management table.

  Thereby, the effect which changes a user's action can be anticipated. For example, if the reservation and / or usage charges are high during peak daytime power consumption and the reservation and / or usage charges are low in the evening after the peak of power consumption, the user can make a reservation during peak daytime power consumption. If the displayed reservation fee and usage fee are high, the possibility of changing to an evening reservation is high. Thus, it can be expected that the power consumption at the peak time is dispersed.

  In this way, when the reservation fee and / or usage fee of the “usage time zone” of the reservation information input by the user is high, the user may be presented with a time zone where the reservation fee and / or usage fee is low. . In this case, the management unit 23 determines whether the reservation fee and / or the usage fee calculated by determining that the reservation information can be reserved is higher than a predetermined value (for example, whether the average value of the reservation fee and / or the usage fee is higher). If it is determined that the reservation fee and / or usage fee is lower than the calculated reservation fee and / or usage fee, the management unit 23 specifies recommended time zone information indicating the identified time zone. It is generated and transmitted to the transmission unit 21.

  When receiving the recommended time zone information, the receiving unit 11 of the terminal 1 sends it to the display unit 12. Based on the recommended time zone information, the display unit 12 displays a time zone in which the reservation fee and / or the usage fee is lower than the input usage time zone in the column of the usage time zone of the corresponding reservation information on the reservation screen. . Thereby, the effect which changes a user's action further improves.

  In the example of FIG. 3, the reservation information 4 cannot be reserved. If the management unit 23 determines that the reservation information 4 cannot be reserved, the management unit 23 generates reservation impossible information indicating that the reservation information 4 cannot be reserved, and causes the transmission unit 21 to transmit the reservation information 4. When receiving the reservation disabling information, the receiving unit 11 of the terminal 1 sends it to the display unit 12 and the storage unit 14. Based on the reservation impossible information, the display unit 12 indicates that reservation is impossible at the input portion of the reservation information 4 on the reservation screen as shown in FIG. Is displayed. The display based on the reservation impossible information is not limited to the message, but may be a symbol, a color change, a character change, or the like. In addition, when the storage unit 14 of the terminal 1 receives the reservation impossible information from the reception unit 11, the storage unit 14 deletes the reservation information 4.

  Next, a method for calculating the accumulated power consumption, excess power consumption, and unused power consumption will be described. The power consumption amount acquisition unit 15 of the terminal 1 acquires power consumption amount information during the use time period of the reservation information 1 to 3 stored in the storage unit 14, and the transmission unit 16 transmits the power consumption amount information to the server 2. send. When the management unit 23 of the server 2 receives the power consumption information from the reception unit 22, the management unit 23 extracts an entry with a matching “user ID” from the reservation management table stored in the storage unit 24. The management unit 23 identifies an entry including the date and time when “use date” and “use time zone” are associated with the power consumption information among the entries having the same “user ID”. The management unit 23 adds the value of the power consumption indicated by the power consumption information to the value of “cumulative power consumption” associated with the identified entry. In this way, the management unit 23 accumulates and stores the power consumption received in the usage time zone for each entry.

  When the value of “cumulative power consumption” when the “use time zone” of “use date” of each entry ends exceeds the value of “reserved power consumption” of the entry, the management unit 23 It is determined that the amount exceeds the reserved amount. When the value of “cumulative power consumption” when the “usage time period” of “use date” of each entry ends does not exceed the value of “reserved power consumption” of the entry, the management unit 23 It is determined that the amount does not exceed the reserved amount.

  When the management unit 23 determines that the power consumption exceeds the reserved amount, the management unit 23 calculates the excess power consumption by subtracting the “reserved power amount” from the “cumulative power consumption”. Are stored as “excess power” in association with the reservation management table entry. In the example of FIG. 4, the “cumulative power consumption” of the entry whose “user ID” is 0001, “use date” is 2011/08/01, and “use time zone” is 12:00 to 17:00 is 3250 Wh. The “reserved power amount” is 3200 Wh. Therefore, the “excess electric energy” is 50 Wh.

  When the management unit 23 determines that the power consumption does not exceed the reserved amount, the value of the “cumulative power consumption” when the “use time zone” of the “use date” of each entry ends is It is determined whether or not the “reserved power amount” value of the entry is insufficient. If it is determined that the power consumption is insufficient for the reservation, the value of “cumulative power consumption” is subtracted from the value of “reserved power” to calculate the insufficient power consumption, and the entry in the reservation management table of FIG. And stored as “unused electric energy”. In the example of FIG. 4, the “cumulative power consumption” of the entry having “user ID” 0001, “use date” 2011/08/01, and “use time zone” 13:00:00 to 14:00 is 300 Wh. The “reserved power amount” is 400 Wh. Therefore, the “unused electric energy” is 100 Wh.

  Assuming that the current date and time is 13:00 on 2011/08/08, the “user ID” is 0002, the “use date” is 2011/08/02, and the “use time zone” is 12:00 to 17:00. The “cumulative power consumption” of the entry is the power consumption 250 Wh consumed from 12:00 to 13:00. In addition, when the “cumulative power consumption” is not too much or less than the “reserved power consumption”, “−” is displayed in the columns of “excess power consumption” and “unused power consumption” in FIG. Also, “-” is displayed when the use time period has not started.

  FIG. 5 is a flowchart showing an example of the operation of the terminal according to the embodiment. When the user accesses the server 2 using the terminal 1, the receiving unit 11 of the terminal 1 receives the reservation screen information from the server 2 (step S11). The display unit 12 displays a reservation screen based on the reservation screen information (step S12). The user views the reservation screen displayed on the display unit 12 and inputs a power reservation to the input unit 13. The input unit 13 acquires reservation information indicating a reservation of power input by the user (step S13). The storage unit 14 stores reservation information (step S14). The transmission unit 16 transmits the reservation information to the server 2 (Step S15).

  When the reception unit 11 receives the reservation impossible information from the server 2 (step S16; YES), the display unit 12 indicates on the reservation screen that the power input by the user cannot be reserved based on the reservation impossible information. (Step S17). Moreover, the memory | storage part 14 deletes the reservation information corresponding to reservation impossible information (step S18), and a process transfers to step S21.

Information and usage fee information are received (step S19). Based on the reservation fee information and the usage fee information, the display unit 12 displays the reservation fee and the usage fee for the power input entered by the user on the reservation screen (step S20).

  If the reservation screen has not ended (step S21; NO), the process returns to step S13, and steps S13 to S21 are repeated. When the reservation screen is terminated (step S21; YES), the power consumption acquisition unit 15 determines whether or not the use time period of the reservation information stored in the storage unit 14 has started (step S22). If the use time period has not started (step S22; NO), step S22 is repeated. When the usage time period starts (step S22; YES), the power consumption amount acquisition unit 15 acquires power consumption amount information indicating the power consumption amount from each watt-hour meter in the home (step 23). The transmission unit 16 transmits the power consumption information to the server 2 (step S24). If the use time period has not ended (step S25; NO), the process returns to step S23, and steps S23 to S25 are repeated. If the use time period has ended (step S25; YES), the process ends.

The receiving unit 22 receives reservation information from the terminal 1 (step S32). The management unit 23 determines whether or not the power input by the user can be reserved based on the reservation information (step S33). When it is determined that the reservation is impossible (step S33; NO), the transmission unit 21 transmits the reservation impossible information to the terminal 1 (step S34), and the process proceeds to step S38. When it is determined that the reservation is possible (step S33; YES), the management unit 23 registers the reservation information in the reservation management table stored in the storage unit 24 (step S35). Further, the management unit 23 calculates a reservation fee and a usage fee for the reservation indicated by the reservation information (step S36). The transmission unit 21 transmits the reservation fee information indicating the reservation fee and the usage fee information indicating the usage fee to the terminal 1 (step S37).

  If the reservation screen has not ended (step S38; NO), the process returns to step S32, and steps S32 to S38 are repeated. When the reservation screen is terminated (step S38; YES), the receiving unit 22 receives power consumption information from the terminal 1 (step 39). The storage unit 24 adds the power consumption value indicated by the power consumption information received by the reception unit 22 to the “cumulative power consumption” value in the reservation management table (step S40).

  If the use time period has not ended (step S41; NO), the process returns to step S39, and steps S39 to S41 are repeated. When the usage time period has ended (step S41; YES), the management unit 23 determines whether or not the power consumption exceeds the reserved amount based on the reservation management table (step S42). When it is determined that the reserved amount has been exceeded (step S42; YES), the storage unit 24 stores the excess power amount calculated by the management unit 23 in the reservation management table (step S43), and the process proceeds to step S44. On the other hand, if it is determined that the reserved amount has not been exceeded (step S42; NO), the management unit 23 determines whether or not the power consumption is insufficient for the reserved amount based on the reservation management table (step S44). ). If it is determined that the reserved amount is insufficient (step S44; YES), the storage unit 24 stores the unused power amount calculated by the management unit 23 in the reservation management table (step S45), and the process proceeds to step S46. When it is determined that there is not a shortage for the reservation (step S44; NO), the management unit 23 charges the user based on the reservation management table stored in the storage unit 24 (step S46), and ends the process.

  As described above, according to the power consumption management system 100 of the embodiment, the user can know in advance how much power he / she will consume by reserving power, It is possible to suppress the power consumption behavior of users in a plurality of households as targets, and prevent the total power consumption of each household from exceeding a predetermined value.
