Description

  The present invention generally relates to a charge system management apparatus and a charge system management system, and more particularly to a charge system management apparatus and a charge system management system for creating an electricity charge system that reflects user demands.

  A user purchases electricity from an electric power company such as an electric power company and pays the price as an electric charge. Currently, various electricity billing systems (electricity billing plans) are prepared, and the user selects the appropriate electricity billing system according to the usage pattern such as the amount of electricity used, the hours of electricity usage, the place of electricity usage, etc. And make a contract with an electric utility.

  There is an electricity rate system in which the electricity rate unit price varies depending on the time zone. For example, in the time zone from 7:00 to 23:00, an expensive electricity rate unit price is set, and in the time zone from 23:00 to 7:00 Cheaper electricity unit price is set. A system has been proposed that presents a user with a message recommending the use of an electric device in a time zone where the unit price of electricity is low based on the actual usage of electricity (for example, Document 1 “Japanese Patent Publication No. 2008”). -202984 ").

  In recent years, depending on an increase in power demand, power generation conditions, and the like, when attention is paid to commercial power, there is a risk of power supply shortage exceeding the power supply amount. In this case, the user needs to refrain from using commercial power, suppress the power demand peak, and prevent the occurrence of insufficient power supply.

  However, the user must select an electricity rate system from the limited electricity rate system determined by the electric power company, and the user may have a peak power demand depending on the content of the selected electricity rate system. There was a case that the action to suppress was restricted.

  For example, in general, even if the user intends to shift the usage time (equipment usage time) of electrical equipment in order to suppress the power demand peak, if the electricity rate system does not match the equipment usage time, an action to suppress the power demand peak It may not be easy to actually execute.

  In addition, the power company wants to suppress the power demand peak as much as possible from the viewpoint of improving the stability of power supply. However, multiple users who use the same electricity billing system often use the same type of electrical equipment, so the power demand peak tends to be high, which is what electric utilities think. It will be contrary.

  The present invention has been made in view of the above-mentioned reasons, and the purpose thereof is a charge system management device that makes it easy to suppress a power demand peak without restricting a user's action for suppressing the power demand peak as much as possible, and a charge. It is to provide a system management system.

(Embodiment 1)
FIG. 1 shows a configuration of a charge system management system of the present embodiment.

  The fee structure management system includes a fee structure management device 1 (hereinafter abbreviated as a management device 1), a user terminal 2, a router 3, and a server 4 as main components.

  The management device 1, the user terminal 2, and the router 3 are installed in a building such as an apartment house, a detached house, an office, a tenant of a building, and the server 4 is installed in a remote location outside. The server 4 is connected to a wide area network 5 such as the Internet. The management device 1 is connected to the wide area network 5 via the router 3. The management device 1 and the user terminal 2 are configured to be able to communicate with each other via a home network 6 configured with a wireless or wired HAN (Home Area Network). Since communication using the Internet, HAN, etc. is well known, detailed description is omitted.

  A user purchases electricity from an electric power company such as an electric power company and pays the price as an electric charge. Usually, the user selects one electricity charge system from a plurality of electricity charge systems (electricity charge plans) prepared in advance by the electric power company, and contracts with the electricity business. FIG. 2 shows an electricity billing system 101 that the user initially contracted. In the electricity billing system 101, an expensive electricity bill unit price [Px1] is set in the daytime time zone [Tx1], and the nighttime zone [Tx2] is cheaper. Electricity unit price [Px2] is set.

  However, even if the user intends to shift the usage time of electric equipment (equipment usage time) to suppress the power demand peak, if the electricity billing system does not match the equipment usage time, the action to suppress the power demand peak actually It may not be easy to execute.

  Therefore, in the present embodiment, the management device 1 presents the user with an electricity billing system that makes it easy to suppress the power demand peak without restricting the action for the user to suppress the power demand peak as much as possible. In addition, the action which suppresses the electric power demand peak by a user is called peak suppression action.

  Hereinafter, the process of presenting the electricity charge system to the user will be described using the flowchart of FIG. 3 and the electricity charge system 102 of FIG.

  The user terminal 2 includes an operation unit 21, a display unit 22, and a communication unit 23, and is configured by any one of a dedicated terminal, a mobile phone, a smartphone, a tablet, and a personal computer. The operation unit 21 includes a user interface such as a touch panel and a switch, and creates instruction information Y1 by a user operation. The instruction information Y1 is information for instructing a specific time zone that is a time zone to which a specific electricity bill unit price is applied.

  First, in this embodiment, an electricity bill system 102 is created in which the electricity bill unit price varies in three stages depending on the time zone. The unit price of electricity charges at each stage is [P1], [P2], and [P3] in order from the lowest. And a user operates the operation part 21, and applies the highest electricity rate unit price [P3] (maximum rate unit price [P3]) according to the usage pattern of the electricity which he is going to perform by own peak suppression action. The start time and end time of the specific time zone [T3] which is the time zone are set. For example, the user sets a specific time zone [T3] as a time zone in which he / she intends to refrain from using electricity.

  Furthermore, the user operates the operation unit 21 to set the start time and the end time of the specific time period [T2] according to the electricity usage pattern that the user wants to perform with his / her peak suppression behavior. The specific time zone [T2] is a time zone in which the second highest electricity unit price [P2] is applied. And the time slot | zone to which the lowest electricity bill unit price [P1] is applied becomes other than specific time slot | zones [T3] and [T2]. The electricity billing system to be created may be a system in which the electricity bill unit price fluctuates in two stages or four or more stages. The number of specific time zones set by the user is the number of fluctuations in the electricity bill unit price of the electricity billing system to be created. It is set appropriately according to

  Then, the operation unit 21 generates instruction information Y1 indicating (instructing) specific time zones [T3] and [T2], and the communication unit 23 transmits the instruction information Y1 to the management apparatus 1 via the home network 6. To do.

  Signals exchanged between the management device 1, the user terminal 2, and the server 4 are given in advance to each of the management device 1, the user terminal 2, and the server 4 in order to identify the transmission source and the transmission destination. Identification information (address information, etc.).

  The management device 1 includes a first communication unit 11 (information acquisition unit), a second communication unit 12 (communication unit), and a system creation unit 13.

  The first communication unit 11 has a function of communicating with the communication unit 23 of the user terminal 2 via the home network 6, and the first communication unit 11 receives the instruction information Y <b> 1 from the user terminal 2. (S1). That is, the first communication unit 11 corresponds to an information acquisition unit that acquires the instruction information Y1.

  Here, in order to restrict the time zone in which the specific time zone [T3] can be set, the restricted time zone [Ta] is set in advance. Then, “the time length Tb of the specific time zone [T3] overlapping the restriction time zone [Ta] is equal to or greater than the predetermined value [K1]” is the restriction condition 1 in consideration of the operation of the electric power company. Therefore, the system creation unit 13 of the management device 1 determines whether or not the specific time zone [T3] satisfies the constraint condition 1 based on the instruction information Y1 (the specific time zone [T3 overlapping the constraint time zone [Ta]). The time length Tb is determined to be equal to or greater than a predetermined value [K1]) (S2). Note that, when the user operates the operation unit 21, the user terminal 2 displays information on the constraint condition 1 on the display unit 22 to alert the user.

  Then, if the specific time zone [T3] does not satisfy the restriction condition 1, the system creation unit 13 sends a reset request Y2 for requesting resetting of the specific time zone [T3] from the first communication unit 11 to the user terminal 2. (S3). In the user terminal 2, the communication unit 23 receives the reset request Y2, and the display unit 22 displays a screen that prompts the user to reset the specific time period [T3].

  On the other hand, if the specific time zone [T3] satisfies the constraint condition 1, the system creation unit 13 reflects the specific time zones [T3] and [T2] set by the user and manages the electric power company. An electricity rate system that satisfies the following constraints 2 and 3 provided for consideration is created (S4).

  The constraint condition 2 is “to create an electricity bill system so that an integral value obtained by time-integrating the electricity bill unit price over one day matches a predetermined value determined in advance”. Specifically, an integral value obtained by time-integrating the electricity rate unit price of the electricity rate system 102 over one day (shaded portion in FIG. 4) is an integral value obtained by time-integrating the electricity rate unit price of the electricity rate system 101 over the day. Must match the value (shaded area in FIG. 2). That is, the constraint condition 2 includes an integral value obtained by integrating the electricity rate unit price of the electricity rate system before the change over a day and an integration value obtained by integrating the electricity rate unit price of the electricity rate system after the change over a day. This is a condition for making values coincide with each other.

  The constraint condition 3 is that “the highest unit price [P3] is set to a predetermined minimum unit price or more”.

  The above restrictions 1 to 3 maintain the revenue neutrality of the electric utility as much as possible (even if the electric utility system contracted before and after the fluctuation of the electric utility system) To keep income as constant as possible). Here, the income of the electric power company is an electricity fee paid by the user.

  The lowest electricity rate unit price [P1] is a predetermined fixed unit price, and the highest rate unit price [P3] and the second highest electricity rate unit price [P2] are variable. The system creation unit 13 selects and sets the highest unit price [P3] and the second highest electricity unit price [P2] from the combinations shown in Table 1.

  That is, the system creation unit 13 reflects the specific time zones [T1], [T2], [T3] set by the user, and the combination of the maximum unit price [P3] and the electricity unit price [P2] from Table 1. To create one or more electricity rate systems that satisfy the constraints 2 and 3. At this point, constraint 1 has already been satisfied.

  Specifically, the system creation unit 13 sets the electricity rate unit price [P1] in the specific time period [T1]. Further, the system creation unit 13 sets the maximum charge unit price [P3] selected from Table 1 in the specific time zone [T3]. Furthermore, the system creation unit 13 sets the unit price [P2] selected from Table 1 for the specific time period [T2]. The system creation unit 13 can create a plurality of electricity rate systems that satisfy the constraints 1 to 3 by changing the combination of the maximum unit price [P3] and the electricity rate unit price [P2].

  Then, the system creation unit 13 causes the first communication unit 11 to transmit the charge system information Y3 including the information on the created electricity rate system to the user terminal 2 (S5). In the user terminal 2, the communication unit 23 receives the charge system information Y3, and the display unit 22 displays information on one or more electricity charge systems. As shown in FIG. 4, the information on the electricity bill system displayed by the display unit 22 is represented in a graph format in which the horizontal axis represents time (time) and the vertical axis represents the electricity bill unit price.

  The user operates the operation unit 21 to select an electricity rate system that suits his / her peak suppression behavior from one or more electricity rate systems displayed on the display unit 22, and selection information for notifying the selection result The communication unit 23 transmits Y4 to the management apparatus 1.

  When the first communication unit 11 of the management device 1 receives the selection information Y4 from the user terminal 2 (S6), the second communication unit 12 sends a change request Y6 for notifying the user's changed electricity billing system to the server 4. Transmit (S7).

  The server 4 is a server managed by an electric power company, and stores contract data for an electricity bill system contracted for each user. The server 4 receives the change request Y6 from the management device 1, and changes the contract data of the user's electricity bill system based on the change request Y6. Thereafter, the user is charged by the electric power company based on the changed electricity billing system.

  In addition, when the electricity bill system displayed on the display unit 22 does not match the user's peak suppression behavior and the user does not select any electricity bill system, the user operates the operation unit 21 to communicate the termination request Y5. Transmission from the unit 23 to the management apparatus 1 In this case, since the first communication unit 11 of the management device 1 receives the termination request Y5 from the user terminal 2 in step S6, the system creation unit 13 discards the created information on the electricity rate system. Then, the system creation unit 13 transmits a reset request Y7 for requesting resetting of the specific time zones [T3] and [T2] from the first communication unit 11 to the user terminal 2 (S8). In the user terminal 2, the communication unit 23 receives the reset request Y7, and the display unit 22 displays a screen that prompts the user to reset the specific time zones [T3] and [T2].

  As described above, since the user himself / herself sets the specific time zone [T3] to which the highest unit price [P3] is applied, the user can easily execute the peak suppression action, and the life when the peak suppression action is executed. Action restrictions are reduced. That is, the electricity bill system presented to the user does not restrict the action for the user to suppress the power demand peak as much as possible.

  Moreover, the electricity bill system presented to the user can maintain the revenue neutrality of the electric utility as much as possible. Furthermore, setting the specific time zone [T3] to which the user himself / herself applies the highest unit price [P3] means that the user himself / herself does not use electricity or uses a small amount of electricity during the specific time zone [T3]. As a result, the certainty that power demand peaks can be suppressed is improved.

  Therefore, the charge system management system using the management device 1 and the management device 1 according to the present embodiment makes it easy to suppress the power demand peak without restricting the action for the user to suppress the power demand peak as much as possible. Can do.

  Moreover, as shown in FIG. 5, the electricity charge system created by the system creation unit 13 can also create an electricity charge system 103 in which the maximum unit price P3 is set in a plurality of time zones. Therefore, the management apparatus 1 can present to the user an electricity billing system that suits the user's various peak suppression behaviors.

  In the present embodiment, the user sets not only the specific time zone [T3] to which the highest unit price [P3] is applied, but also the specific time period [T2] to which the second highest electricity unit price [P2] is applied. ing. However, the user may set only the specific time zone [T3], and the system creation unit 13 may set other specific time zones [T1] and [T2] as appropriate so as to satisfy the constraint condition 2 described above. it can.

  In the present embodiment, the lowest electricity unit price [P1] is a fixed unit price, and the system creation unit 13 combines the highest unit price [P3] and the second highest electricity unit price [P2] in the combinations shown in Table 1. Select from and set. However, the system creation unit 13 can also set the electric power unit prices [P1], [P2], and [P3] by appropriately varying so as to satisfy the above-described constraints 2 and 3.

(Embodiment 2)
FIG. 6 shows a configuration of the management apparatus 1 of the present embodiment. The management apparatus 1 includes a system creation unit 13A, and the process of the system creation unit 13A is different from the process of the system creation unit 13 of the first embodiment. The process of presenting the electricity charge system of this embodiment to the user will be described using the flowchart of FIG. 7 and the electricity charge system 102 of FIG. In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 1, and description is abbreviate | omitted.

  In the present embodiment, the user operates the operation unit 21 to specify the time zone in which the lowest electricity unit price [P1] is applied in accordance with the electricity usage pattern that is going to be performed by the user's own peak suppression behavior. The start time and end time of the time zone [T1] are set. For example, the user considers the time zone that he / she thinks will always use electricity as the specific time zone [T1].

  Then, the operation unit 21 generates instruction information Y11 instructing the specific time zone [T1], and the communication unit 23 transmits the instruction information Y11 to the management apparatus 1 via the home network 6.

  The first communication unit 11 of the management device 1 receives the instruction information Y11 from the user terminal 2 (S11). That is, the first communication unit 11 corresponds to an information acquisition unit that acquires the instruction information Y11.

  Here, in order to constrain the time zone in which the specific time zone [T1] can be set, “the specific time zone [T1] is entirely or partially overlapped with the restricted time zone [Ta]. There is a restriction 4 that must be set so as not to occur. Therefore, the system creation unit 13A of the management device 1 determines whether or not the specific time zone [T1] satisfies the restriction condition 4 based on the instruction information Y11 (the specific time zone [T1] is the restricted time zone [Ta]). (S12). Note that, when the user operates the operation unit 21, the user terminal 2 displays information on the constraint condition 4 on the display unit 22 to alert the user.

  Then, the system creation unit 13A sends a reset request Y12 for requesting resetting of the specific time zone [T1] from the first communication unit 11 to the user terminal 2 if the specific time zone [T1] does not satisfy the constraint condition 4. (S13). In the user terminal 2, the communication unit 23 receives the reset request Y12, and the display unit 22 displays a screen that prompts the user to reset the specific time period [T1].

  On the other hand, if the specific time zone [T1] satisfies the constraint condition 4, the system creation unit 13A reflects the specific time zone [T1] set by the user and satisfies the above-described constraint conditions 2 and 3. A fee system is created (S14).

  The above-mentioned constraints 2 to 4 maintain the revenue neutrality of the electric utility as much as possible even when the electric bill system to which the user contracts changes (the electric utility's revenue before and after the fluctuation of the electric bill). To keep income as constant as possible).

  The lowest electricity bill unit price [P1] is a fixed unit price, and the system creation unit 13A satisfies the above-described constraints 2 and 3, and the electricity bill unit prices [P2] and [P3] and the specific time period [T2]. ] [T3] is set appropriately to create one or more electricity billing systems. The method of setting the electricity unit prices [P2] and [P3] and the specific time periods [T2] and [T3] satisfying the above-described constraints 2 and 3 can be realized using a well-known mathematical method.

  Then, the system creation unit 13A causes the first communication unit 11 to transmit the charge system information Y13 including the information on the created electricity rate system to the user terminal 2 (S15). In the user terminal 2, the communication unit 23 receives the charge system information Y13, and the display unit 22 displays information on one or more electricity charge systems.

  The user operates the operation unit 21 to select an electricity rate system that suits his / her peak suppression behavior from one or more electricity rate systems displayed on the display unit 22, and selection information for notifying the selection result The communication unit 23 transmits Y14 to the management apparatus 1.

  If the 1st communication part 11 of the management apparatus 1 receives selection information Y14 from the user terminal 2 (S16), the 2nd communication part 12 will send the change request Y16 which notifies the electricity bill system after a user change to the server 4. Transmit (S17).

  The server 4 receives the change request Y16 from the management device 1, and changes the contract data of the user's electricity bill system based on the change request Y16. Thereafter, the user is charged by the electric power company based on the changed electricity billing system.

  In addition, when the electricity rate system displayed on the display unit 22 does not match the user's peak suppression behavior and the user does not select any electricity rate system, the user operates the operation unit 21 to communicate the end request Y15. Transmission from the unit 23 to the management apparatus 1 In this case, since the first communication unit 11 of the management device 1 receives the termination request Y15 from the user terminal 2 in step S16, the system creation unit 13A discards the created information on the electricity rate system. Then, the system creation unit 13A transmits a reset request Y17 for requesting resetting of the specific time zone [T1] from the first communication unit 11 to the user terminal 2 (S18). In the user terminal 2, the communication unit 23 receives the reset request Y17, and the display unit 22 displays a screen that prompts the user to reset the specific time period [T1].

  As described above, since the user himself / herself sets the specific time zone [T1] to which the electricity rate unit price [P1], which is the lowest electricity rate unit price, is applied, the peak suppression behavior is easily performed. When you do, life and behavior restrictions are lightened. That is, the electricity bill system presented to the user does not restrict the action for the user to suppress the power demand peak as much as possible.

  Moreover, the electricity bill system presented to the user can maintain the revenue neutrality of the electric utility as much as possible. Furthermore, setting the specific time zone [T1] to which the user himself applies the electric power unit price [P1], which is the lowest electric charge unit price, uses electricity in the specific time zone [T1] or uses a large amount of electricity. That is, the user himself / herself declares. Therefore, the certainty which can suppress an electric power demand peak improves except a specific time slot | zone [T1].

  Therefore, the charge system management system using the management device 1 and the management device 1 according to the present embodiment makes it easy to suppress the power demand peak without restricting the action for the user to suppress the power demand peak as much as possible. Can do.

  The management device 1 of each embodiment described above creates an electricity bill system in which the electricity bill unit price varies depending on the time zone. The management device 1 includes a first communication unit 11 (information acquisition unit), a system creation unit 13 (13A), and a second communication unit 12 (communication unit). The 1st communication part 11 acquires the instruction information showing the specific time slot | zone which is a time slot | zone which applies a specific electricity bill unit price. Based on the instruction information, the system creation unit 13 (13A) creates an electricity bill system in which a specific electricity bill unit price is applied in a specific time zone. The second communication unit 12 transmits the information on the electricity rate system created by the system creation unit 13 (13A) to the user terminal 2 (external). And the system creation part 13 (13A) creates an electricity bill system so that the integral value which carried out the time integration of the electricity bill unit price fluctuate | varied with a time slot | zone over a day corresponds with the predetermined value decided beforehand.

  Therefore, the management apparatus 1 can make it easy to suppress a power demand peak, without restrict | limiting the action for a user to suppress a power demand peak as much as possible.

  Moreover, it is preferable that the specific electricity unit price is the highest electricity unit price (maximum unit price [P3]) in one day.

  In this case, since the user himself / herself sets the specific time zone [T3] to which the highest unit price [P3] is applied, the user can easily execute the peak suppression action. Restrictions are lightened. That is, the electricity bill system presented to the user does not restrict the action for the user to suppress the power demand peak as much as possible.

  In addition, the system creation unit 13 (13A) sets a specific time zone [T3] to which the highest electricity unit price (maximum unit price [P3]) is applied in advance (a restricted time zone [Ta]). It is preferable to create an electricity billing system only when it includes.

  In this case, even if the electricity billing system with which the user contracts changes, the revenue neutrality of the electricity utility is kept as much as possible (the electricity provider's revenue before and after the fluctuation of the electricity billing system is kept approximately constant). )

  Moreover, it is preferable that the specific electricity unit price is the lowest electricity unit price (electricity unit price [P1]) in one day.

  In this case, since the user himself / herself sets the specific time zone [T1] to which the electricity rate unit price [P1], which is the lowest electricity rate unit price, is applied, the peak suppression action is easily performed and the peak suppression action is executed. If you do, life and behavior restrictions will be lightened. That is, the electricity bill system presented to the user does not restrict the action for the user to suppress the power demand peak as much as possible.

  In addition, the system creation unit 13 (13A) may set the highest unit price of electricity price (maximum unit price [P3]) within a day to be equal to or higher than a predetermined minimum unit price in the created electricity charge system. preferable.

  In this case, even if the electricity billing system with which the user contracts changes, the revenue neutrality of the electricity utility is kept as much as possible (the electricity provider's revenue before and after the fluctuation of the electricity billing system is kept approximately constant). )

  The fee structure management system includes a management device 1 and a user terminal 2 that communicates with the management device 1. The user terminal 2 transmits instruction information to the management device 1, and the electric power transmitted by the second communication unit 12. Receives information on the fee structure and notifies the user.
