Description

The present invention relates to an indirect power trading system for negawatts (power reductions).

Conventionally, an electric power trading system targeting the negawatt electric power trading market is known (see, for example, Patent Document 1 and the like).

In addition, a method of electronically providing a user with a coupon (incentive) that can be used at a physical location (real store) during a demand response event that contributes to the generation of negawatt is disclosed (for example, patent documents). 2).

Japanese Patent No. 5875971 Japanese Unexamined Patent Publication No. 2016-143421

However, since Patent Document 1 targets the electric power trading market, there is a high possibility that profits cannot be obtained in small-lot transactions with a relatively small trading amount. In addition, even if the consumer who wants to sell the negawatt and the consumer who wants to buy make a direct transaction, it is basically necessary to make a transaction for the same time zone, so the negawatt of the consumer who wants to sell is supplied. If there is any difference between the time of day and the time of day when the consumer who wants to buy needs negawatt, there is a possibility that a transaction that benefits both parties will not be completed. In addition, even if it is possible for a consumer who wants to sell negawatts and a consumer who wants to buy negawatts to trade in the same time zone, the transportation cost of electricity is required, so the transportation cost is high in small-lot transactions. There is a possibility that the transaction will not be completed, hindering the merits of both parties.

Further, as in Patent Document 2, it is possible to provide an incentive (for example, points, etc.) to the user and promote the execution of the demand response (generation of negawatt), but it is not possible to promote the transaction of negawatt.

Hereinafter, modes for carrying out the invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an example of a configuration of a demand response system 1 (an example of an electric power trading system) according to the present embodiment. The demand response system 1 includes a power supply company 2, an aggregator 3, and a plurality of consumers 4. Hereinafter, the target to be specifically supplied with electric power from the electric power supply company 2 is the electric device 43 described later installed in the house or facility owned by the consumer 4, but abstractly, the electric power is provided by the consumer 4. It may explain that it is the target of supply.

In the figure, the thick solid line represents the power system, and the thin solid line represents the control / information system. Further, the illustrated consumer 4 is shown in a form representing a plurality of consumers 4, and other consumers 4 have the same configuration. Further, in the figure, various devices (smart meter 41, distribution board 42, electric device 43, cutoff unit 44, interlocking switch 45, etc., which will be described later) installed in the house or facility of the customer 4 and the customer 4 possess. The mobile terminal 46 (described later) is illustrated in a mode included in the consumer 4 for convenience.

The electric power supply company 2 supplies electric power to a plurality of consumers 4. The power supply company 2 includes a power supply management server 21 that manages the power supply and a power plant 22 that generates power.

The power supply management server 21 transmits a demand response control command (DR control command) to the aggregator 3 (demand response management server 31 described later), for example, when there is a possibility that a power resource shortage may occur. The power supply management server 21 is communicably connected to the demand response management server 31 via a predetermined network (for example, an Internet network) or the like.

The power plant 22 generates power by any method, for example, hydroelectric power generation, thermal power generation, nuclear power generation, wind power generation, solar power generation, other types of power generation, or any combination thereof. The electric power generated at the power plant 22 is supplied to each of the plurality of consumers 4 through the power transmission network PL.

The aggregator 3 enters between the electric power supply company 2 and the plurality of consumers 4 and performs demand response control. The aggregator 3 includes a demand response management server (DR management server) 31.

The DR management server 31 (an example of the server) performs various processes related to demand response control. The function of the DR management server 31 may be realized by arbitrary hardware, software, or a combination thereof, and is configured around one or a plurality of server computers including, for example, a CPU, RAM, ROM, I / O, and the like. You can. Hereinafter, the functional configuration of the DR management server 31 will be described with reference to FIG.

The DR management server 31 has, for example, a communication processing unit 311 and a demand response control unit (DR control unit) 312 as functional units realized by executing one or more programs stored in the ROM on the CPU. It includes a management unit 313 and an electric power purchase support processing unit 314. Further, the DR management server 31 includes a storage unit 319 as a storage area defined in an internal storage device (internal memory) such as an EEPROM (Electrically Erasable Programmable Read-Only Memory) or a flash memory, for example.

The communication processing unit 311 (an example of the first receiving unit and the third transmitting unit) is a mobile terminal 46 owned by an external device of the DR management server 31, for example, a power supply management server 21 or a consumer 4 through a predetermined network. Various signals (information signals, control signals) are transmitted and received to and from the above. For example, the communication processing unit 311 (first receiving unit) receives the power purchase request (first request signal) described later, which is transmitted from the mobile terminal 46. Further, for example, the communication processing unit 311 (third transmission unit) transmits a demand response request, which will be described later, to the mobile terminal 46 of the consumer 4 in response to the transmission request from the DR control unit 312.

The DR control unit 312 performs demand response control for a plurality of consumers 4 in response to a DR control command received from the power supply management server 21 through the communication processing unit 311. For example, the DR control unit 312 transmits a demand response request (DR request) to all of the plurality of consumers 4. The DR request may include information such as a time zone in which a demand response is required. Further, the DR control unit 312 collects the demand response results for a plurality of customers 4 based on the demand response record information (DR record information) received from the mobile terminal 46 of the customer 4 through the communication processing unit 311. .. Further, the DR control unit 312 transmits information regarding the collected demand response results to the power supply management server 21 via the communication processing unit 311.

As will be described later, the point management unit 313 is given to each of the plurality of consumers 4 according to the amount of power reduction (negawatt) due to the execution of the demand response (specifically, it is defined for each customer 4). It manages the identification information to be provided, for example, points (virtual consideration different from money) given in a manner associated with a user ID (Identification) or the like. For example, the point management unit 313 performs a process of registering (storing) the latest point information received from the mobile terminals 46 owned by each of the plurality of consumers 4 in the storage unit 319 through the communication processing unit 311. As a matter of course, the point information 3191 stored in the storage unit 319 includes the point information of each of the plurality of consumers 4, and each point information is the identification information (user ID, etc.) defined for each of the plurality of consumers 4. ) Is stored in the form associated with it.

The electric power purchase support processing unit 314 receives the electric power of the consumer 4 from the mobile terminal 46 of the consumer 4 through the communication processing unit 311 in response to the electric power purchase request and the electric power purchase end notification (both described later). Perform processing to support purchase. For example, the electric power purchase support processing unit 314 transmits information regarding the electric power purchase amount included in the electric power purchase end notification to the electric power supply management server 21 via the communication processing unit 311. As a result, the electric power supply company 2 reflects the electric power purchase amount by using the points in the usage fee of the consumer 4, that is, the electric power supply company 2 subtracts the electric power purchase amount by using the points from the usage fee. The consumer 4 can indirectly purchase electricity with points. In other words, the electric power purchase support processing unit 314 performs a process of pretending that a part of the electric power supplied from the electric power supply company 2 to the consumer 4 is purchased by using points.

Further, the electric power purchase support processing unit 314 uses the communication processing unit 311 to calculate information (point electric power conversion stored in the storage unit 319) for calculating the value of points when purchasing electric power (point electric power conversion value). The value information 3192) is transmitted to the mobile terminal 46.

The point power conversion value information 3192 stored in the storage unit 319 may be updated. In this case, the electric power purchase support processing unit 314 transmits the updated data to the mobile terminal 46 every time the point electric power conversion value information 3192 is updated.

Returning to FIG. 1, a smart meter 41, a distribution board 42, an electric device 43, a cutoff unit 44, and an interlocking switch 45 are provided in the house or facility owned or exclusively owned by the customer 4. In addition, the consumer 4 possesses the mobile terminal 46.

The smart meter 41 is a watt hour meter provided on a power line (internal line) drawn into the house from the power transmission network PL. The smart meter 41 measures the amount of electric power used from the power transmission network PL to the electric device 43 via the distribution board 42. Further, the smart meter 41 has a built-in communication device (not shown), and supplies information (power usage information) regarding the power consumption for each predetermined period (for example, 30 minutes) via a predetermined network, for example. It is transmitted to the management server 21. Similarly, the smart meter 41 also uses, for example, a local network in the home (WiFi (registered trademark) network) or a predetermined short-range communication means (for example, Bluetooth (registered trademark) or NFC (Near Field Communication) communication). The power usage information is transmitted to the mobile terminal 46 via the mobile terminal 46.

The distribution board 42 branches the extension line into a plurality of branch lines and supplies electric power to each electric device 43 (electric device 43-1 to 43-N) connected to each branch line. The distribution board 42 is provided with a circuit breaker (breaker) for each branch line.

The electric device 43 is installed in the house of the consumer 4, and may be, for example, an air conditioner, a lighting, an IH stove, a floor heating device, or the like. The electrical device 43 includes electrical devices 43-1 to 43-N (an integer greater than or equal to N: 1).

In the figure, each electric device 43-1 to 43-N is connected to a different branch line for convenience. For example, even if a plurality of electric devices 43 are connected to the same branch line through a plurality of outlets. Good.

The cutoff unit 44 is provided in each branch line connected from the distribution board 42 to the electric devices 43-1 to 43-N, and electrically connects each branch line in response to a control command from the interlocking switch 45 described later. It switches to a cut-off state or returns from an electrically cut-off state to an electrically connected state. The blocking unit 44 may be, for example, a mechanical relay, a semiconductor relay, or the like. The cutoff unit 44 includes a cutoff unit 44-1 to 44-N corresponding to each branch line (each electric device 43-1 to 43-N).

The cutoff unit 44 is provided in all the branch lines, but is provided only in a part of the branch lines (specifically, the branch line to which the electric device 43 that uses a relatively large amount of electric power is connected). There may be.

The interlocking switch 45 is communicably connected to the mobile terminal 46, and is provided as a blocking unit 44 (blocking units 44-1 to 44) on the branch line specified by the blocking request in response to the blocking request transmitted from the mobile terminal 46. Send a cutoff command to one or more of -N). As a result, the cutoff unit 44 designated according to the predetermined operation of the user (customer 4) in the mobile terminal 46 electrically cuts off the corresponding branch line. Therefore, the electric device 43 (one or more of the electric devices 43-1 to 43-N) connected to the branch line is not supplied with electric power, and the electric power consumption by the electric device 43 becomes substantially zero. Become. Further, the interlocking switch 45 is one or a plurality of cutoff units 44 (one or a plurality of cutoff units 44-1 to 44-N) provided on the branch line specified by the connection request in response to the connection request transmitted from the mobile terminal 46. ) To send a connection command. As a result, the cutoff unit 44 that has received the connection command returns the electrically cut off branch line to the electrically connected state. The function of the interlocking switch 45 may be realized by any hardware, software, or a combination thereof.

The mobile terminal 46 is an arbitrary terminal that can be carried by the user (customer 4). The mobile terminal 46 is a general-purpose terminal such as a mobile phone, a smartphone, a tablet terminal, or a portable computer. Hereinafter, the functional configuration of the mobile terminal 46 will be described with reference to FIG.

The mobile terminal 46 may be, for example, a stationary terminal such as a desktop computer as long as the same functions described later can be realized.

FIG. 3 is a functional block diagram showing an example of the functional configuration of the mobile terminal 46. The mobile terminal 46 is, for example, a predetermined application (specifically, a processing device mainly composed of a CPU, RAM, ROM, I / O, etc. built in the mobile terminal 46) installed in the mobile terminal 46 (specifically, a processing device mainly composed of a CPU, RAM, ROM, I / O, etc.). Communication processing unit 461, display processing unit 462, demand response execution processing unit (DR execution processing unit) 463 as functional units realized by starting the program) on the OS (Operating System) installed on the mobile terminal 46. , The power reduction amount calculation unit 464, the point granting unit 465, the point management unit 466, and the power purchase processing unit 467 are included. Further, the mobile terminal 46 includes, for example, a storage unit 469 as a storage area defined in a built-in storage device (built-in memory) such as EEPROM and flash memory.

The communication processing unit 461 controls a communication device (for example, a mobile communication module, a WiFi module, a Bluetooth (registered trademark) module, an NFC module, etc.) equipped as standard in the mobile terminal 40, and controls an external device, that is, an aggregator 3. The control signal, information signal, etc. are transmitted and received between the DR management server 31, the smart meter 41, and the interlocking switch 45. For example, the communication processing unit 461 (first transmission unit) transmits a power purchase request (first request signal), which will be described later, to the DR management server 31 in response to a transmission request from the power purchase processing unit 467. Further, for example, the communication processing unit 461 (third receiving unit) receives the DR request transmitted from the DR management server 31.

The display processing unit 462 performs processing for displaying various screens on the display unit (for example, a touch panel type liquid crystal display or the like) of the mobile terminal 46. For example, the display processing unit 462 displays an operation screen (DR operation screen) for the user (customer 4) to execute and end the demand response in response to a request from the DR execution processing unit 463. Perform the process of displaying. Further, for example, the display processing unit 462 displays an operation screen (power purchase operation screen) for the user (customer 4) to perform an operation of purchasing power by using the points by the function of the power purchase processing unit 467. Display on the department. Further, for example, the display processing unit 462 has a total value (possession) of the current points associated with the identification information corresponding to the consumer 4 who uses the mobile terminal 46 in response to the request from the power purchase processing unit 467. The value (point power conversion value) when used for power purchase of points) is displayed on the display unit.

In other words, the possessed points are the points (accumulated points) already given to the identification information corresponding to the consumer 4 by the point management unit 466, which will be described later, and are already used for purchasing electric power. Represents the current total value (total value) of points excluding.

When a DR request is received from the DR management server 31 through the communication processing unit 461, the DR execution processing unit 463 executes a demand response in response to a predetermined operation on the mobile terminal 46 by the user (customer 4). Specifically, the DR execution processing unit 463 causes the display unit to display the DR operation screen via the display processing unit 462. More specifically, for example, the display processing unit 462 includes an operation unit for selecting the execution and termination of the demand response on the display unit in response to a request from the DR execution processing unit 463, and an electric device 43 subject to the demand response. A DR operation screen including an operation unit for selecting (43-1 to 43-N) is displayed on the display unit. Each operation unit is realized as, for example, a virtual button icon that can be operated by a touch operation on the surface of the touch panel type liquid crystal display as a display unit. Then, the DR execution processing unit 463 issues a cutoff request according to the operation content of the user (customer 4) on the DR operation screen (for example, the electric device 43 to be the demand response target designated on the operation screen). It is generated and the cutoff request is transmitted to the interlocking switch 25 via the communication processing unit 461. As a result, as described above, the cutoff unit 44 corresponding to the operation content on the DR operation screen electrically cuts off the branch line, so that the electric device 43 (electrical device 43-1 to 43-) connected to the branch line is connected. Power is not supplied to one or more of N), and demand response (reduction of power consumption) is executed.

Further, the DR execution processing unit 463 ends the demand response in response to a predetermined operation on the mobile terminal 46 by the user (customer 4) who is executing the demand response. Specifically, when an operation (end operation) to end the demand response is performed on the DR operation screen, the DR execution processing unit 463 generates a connection request, and the DR execution processing unit 463 generates a connection request via the communication processing unit 461. The connection request is transmitted to the interlocking switch 25. As a result, the interlocking switch 25 transmits a connection command to the cutoff unit 44 in which the branch line is cut off, so that all the electrically cut off branch lines are electrically connected. The demand response ends.

The DR execution processing unit 463 may determine the execution period (for example, end time, etc.) of the demand response according to the operation content on the DR operation screen described above. In this case, when the DR execution processing unit 463 confirms the elapse of the execution period, the demand response is terminated.

The power reduction amount calculation unit 464 calculates the actual demand response, that is, the power reduction amount (negawatt) due to the execution of the demand response during the execution of the demand response. For example, the power reduction amount calculation unit 464 has a history of power usage information received from the smart meter 41 through the communication processing unit 461, and an electric device 43 connected to the cutoff unit 44 (branch line in the cutoff state) in the cutoff state. Amount of power reduction by arbitrarily applying a known method, for example, a method disclosed in Japanese Patent Application Laid-Open No. 2016-1987, Japanese Patent Application Laid-Open No. 2014-178066, Japanese Patent No. 5875971 and the like. May be calculated. For example, the power reduction amount calculation unit 464 may calculate the power reduction amount based on the power usage pattern previously defined by the consumer 4, specifically, the pattern of the electric device 43 or the like used for each time zone. ..

The DR execution processing unit 463 performs a process of reducing the power consumption in the house or facility of the customer 4, that is, a process of generating negawatts, regardless of whether or not the communication processing unit 461 receives the DR request. May be good. That is, the DR execution processing unit 463 displays the DR operation screen on the display unit through the display processing unit 462, and causes the blocking unit 44 to display the DR operation screen according to the operation content of the user (customer 4) on the DR operation screen. You may send a cutoff command. In this case, the power reduction amount calculation unit 464 calculates the power reduction amount in a state where the processing for reducing the power consumption is being performed regardless of whether or not the demand response is being executed. Further, the mobile terminal 46 (communication processing unit 461) may be in a mode of acquiring power usage information from the power supply company 2 (for example, the power supply management server 21). In this case, the mobile terminal 46 may acquire the power usage information from the power supply management server 21 via the DR management server 31, or directly connects to the power supply management server 21 and from the power supply management server 21. You may acquire the power consumption information of the smart meter 41.

The point giving unit 465 gives points to the consumer 4 as a consideration (incentive) according to the power reduction amount (magnitude) calculated by the power reduction amount calculation unit 464. Specifically, as described above, the point management unit 466 assigns points to the identification information in a manner of associating the identification information (user ID or the like) defined for each of the plurality of consumers 4. Hereinafter, for the sake of simplicity, giving points to the identification information corresponding to the customer 4 may be described as simply giving points to the customer 4.

The point awarding unit 465 may award points at a constant awarding ratio, for example, awarding 1 point for a power reduction amount of 1 kW. Further, the point giving unit 465 may change the point giving ratio to the power reduction amount according to, for example, the magnitude of the power reduction amount by the demand response, the time zone, the season, and the like. Further, the point giving unit 465 may give a larger number of points as the amount of power reduction increases, for example.

The point management unit 466 stores the points given by the point giving unit 465 as the point information 4691 and manages the point information 4691 (for example, updating the points). Specifically, in the management of the point information 4691 by the point management unit 466, the points P (i) (i: identification for identifying the point grant for each reduction in power consumption). The number. For example, i = 1,2,3, ...) may have an expiration date, and if it is not used within the period up to the expiration date, it will expire, that is, the value will be zero. Further, for example, the value of the points P (i) given by reducing the power consumption each time may be changed according to the elapsed time from the points given, that is, the points themselves may change.

For example, FIG. 4 is an example of a function F (x) that defines a point P (i) given by each reduction in power consumption. With the variable x as the elapsed time from the point assignment, the function F (x) decreases as the elapsed time x from the assignment increases, and becomes zero after a predetermined period (365 days in this example). .. Further, the decrease rate of the function F (x) increases as the elapsed time from the addition increases. For example, the value obtained by multiplying the function F (x) by the coefficient α (> 0) determined according to the magnitude of the power reduction amount may be set as the point P (i) (P (i) = α · F (x)). ). As a result, it is possible to realize the point P (i) whose value decreases with the passage of time from the point grant and the value becomes zero after the lapse of a predetermined period.

The point P (i) given by reducing the power consumption may be in a mode in which either the expiration date or the value fluctuation is applied. That is, the point P (i) may be in a mode in which only the expiration date is provided and the value (point itself) does not change until the expiration date. On the contrary, the value (point itself) of the point P (i) may change according to the elapsed time from the point grant, on the premise that the expiration date is not set.

Returning to FIG. 3, when the point management unit 466 stores the points given by the point giving unit 465 in the storage unit 469, the point management unit 466 provides information (for example, acquisition date) regarding the date and time when the points P (i) are given each time. The point information 4691 may be generated and stored in the storage unit 469 in a manner that can be distinguished from the points P (i) given in the past. As a result, the value of a plurality of points given at different times can be updated ex post facto.

Hereinafter, the processing flow by the DR execution processing unit 463, the power reduction amount calculation unit 464, the point giving unit 465, and the point management unit 466 will be described with reference to FIGS. 5 and 6.

First, FIG. 5 shows a series of processes by the DR execution processing unit 463, the power reduction amount calculation unit 464, the point granting unit 465, and the point management unit 466, that is, from the execution of the demand response to the reduction of the power consumption to the consumer 4. It is a flowchart which shows an example of a series of processing until the point is given and the possession point is updated. The process according to this flowchart may be executed, for example, when a DR request is received from the DR management server 31 by the communication processing unit 461.

In step S102, the DR execution processing unit 463 executes the demand response according to the operation content on the above-mentioned DR operation screen. Specifically, as described above, the DR execution processing unit 463 transmits a cutoff request to the interlocking switch 45 according to the operation content on the DR operation screen.

In step S104, the DR execution processing unit 463 records the DR results. Specifically, the DR execution processing unit 463 buffers the power usage information received from the smart meter 41 through the communication processing unit 461 and the information regarding the cutoff unit 44 that is cut off in a memory buffer or the like.

In step S106, the DR execution processing unit 463 determines whether or not to continue the demand response. For example, the DR execution processing unit 463 may determine whether or not to continue the demand response depending on whether or not an operation (end operation) for ending the demand response has been performed on the DR operation screen during the execution of the demand response. .. Further, for example, when the execution period of the demand response is specified according to the operation content on the above-mentioned DR operation screen, the DR execution processing unit 463 continues the demand response depending on whether or not the execution period has elapsed. It may be determined whether or not to do so. The DR execution processing unit 463 returns to step S104 when continuing the demand response, repeats the processes of steps S104 and S106, and proceeds to step S108 when the demand response is not continued.

In step S108, the power reduction amount calculation unit 464 calculates the power reduction amount due to the execution of the demand response this time.

In step S110, the point giving unit 465 calculates the point P (i) given to the consumer 4 by the demand response (reduction of power consumption) this time (hereinafter, referred to as the point P (i) this time). In addition, the point management unit 466 has not yet used the points given to the consumer 4 by the past demand response (reduction of power consumption) (hereinafter referred to as accumulated points P (i)). Is updated according to the elapsed time from the grant.

In step S112, the point management unit 466 adds (accumulates) information about the point P (i) to the point information 4691 this time, and points given to the customer 4 each time calculated and updated in step S110 ( This time, the possessed points of the point information 4691 are updated by the total value of the points P (i) and the accumulated points P (i)).

In step S114, the DR execution processing unit 463 and the point management unit 466 each transmit the DR actual information and the point information to the DR management server 31 via the communication processing unit 461, and end the current processing.

Subsequently, FIG. 6 is a flowchart schematically showing an example of a process (point update process) for updating possessed points by the point management unit 466. The process according to this flowchart may be executed, for example, every predetermined cycle (for example, every 24 hours).

In step S202, the point management unit 466 refers to the point information 4691 of the storage unit 469.

In step S204, the point management unit 466 updates each accumulated point P (i) according to the elapsed time from the granting.

In step S206, the point management unit 466 updates the possessed points of the point information 4691 with the total value of each accumulated point P (i) updated in step S204.

In step S208, the point management unit 466 transmits the point information to the DR management server 31 via the communication processing unit 461, and ends the current processing.

Returning to FIG. 3, the electric power purchase processing unit 467 performs a process of purchasing the electric power supplied to the electric power 4 at the possession point according to the operation content of the user (customer 4) on the above-mentioned electric power purchase operation screen. Specifically, the display processing unit 462 causes the display unit to display a power purchase operation screen including an operation unit for displaying the point power conversion value, an operation unit for executing power purchase at possessed points, and the like.

When a predetermined operation on the power purchase operation screen (that is, an operation on the operation unit for displaying the point power conversion value) is performed, the power purchase processing unit 467 points to the display unit via the display processing unit 462. Execute the process of displaying the power conversion value (point power conversion value display process). Information for calculating the point power conversion value (point power conversion value information 4692), for example, the amount of power that can be purchased per unit point, is obtained from the DR management server 31 (power purchase support processing unit 314) as described above. The point power conversion value information transmitted to the mobile terminal 46 and received by the communication processing unit 461 is stored in the storage unit 469 (point power conversion value information 4692). The point power conversion value may be a constant value as long as the point power conversion value information 4692 is not updated, and may be, for example, according to the time division within a predetermined period (1 day, 1 year, etc.). It may be a variable mode.

For example, FIG. 7 is a diagram showing an example in which the point power conversion value fluctuates according to the time zone of the day. In this example, the point power conversion value fluctuates gradually so that it is relatively high in the daytime and relatively low in the nighttime. Normally, the daytime power is relatively high, but by setting the point power conversion value relatively high in the daytime, the user (customer 4) can have an opportunity to purchase power at a low price. , It is possible to encourage the user to purchase electric power and execute a demand response using the points given to the user. Further, for example, FIG. 8 is a diagram showing an example in which the point power conversion value fluctuates according to the season of the year. In this example, the point power conversion value is highest in summer and fluctuates moderately so that it is relatively low in other seasons. Normally, in summer, the amount of electricity used peaks and the electricity is relatively high, but the point electricity conversion value is set to the highest in summer, so that the user (customer 4) can purchase electricity at a low price. In addition to being able to obtain opportunities, it is possible to encourage users to purchase electricity and execute demand response using the points given to them.

Returning to FIG. 3, when the power purchase processing unit 467 performs a predetermined operation on the power purchase operation screen (that is, an operation on the operation unit for executing the power purchase at the possession point), the power purchase processing unit 467 powers at the possession point. Performs the process of purchasing (electric power purchase process).

Hereinafter, the processing flow of the point power conversion value display processing and the power purchase processing by the power purchase processing unit 467 will be described with reference to FIGS. 9 and 10.

First, FIG. 9 is a diagram showing an example of point power conversion value display processing by the power purchase processing unit 467.

In step S302, the power purchase processing unit 467 refers to the point information 4691 (possession points included in the storage unit 469) and the point power conversion value information 4692 of the storage unit 469. As described above, the point power conversion value information 4692 is stored in the storage unit 319 of the DR management server 31. The point power conversion value information 3192 is received from the DR management server 31 via the communication processing unit 461 and is stored in the storage unit. This is the information stored in 469. Further, as described above, the point power conversion value information 4692 is based on the updated point power conversion value information 3192 transmitted from the DR management server 31 to the mobile terminal 46 when the point power conversion value information 3192 is updated. Will be updated.

The mobile terminal 46 (power purchase processing unit 467) accesses the DR management server 31 via the communication processing unit 461 and stores the point power conversion value information 3192 stored in the storage unit 319. The point power conversion value information 4692 of the part 469 may be updated and the information may be used.

In step S304, the power purchase processing unit 467 calculates the point power conversion value.

In step S306, the power purchase processing unit 467 sends a display request for the point power conversion value to the display processing unit 462. The display processing unit 462 displays the point power conversion value on the display unit in response to the display request. As a result, the user (customer 4) can confirm the point power conversion value (value of the points currently possessed when purchasing power).

Subsequently, FIG. 10 is a flowchart schematically showing an example of the power purchase process by the power purchase processing unit 467.

In step S402, the power purchase processing unit 467 performs a process of displaying the point power conversion value on the display unit via the display processing unit 462. That is, in step S402, the power purchase processing unit 467 performs the same processing as in steps S302 to S306 of FIG. This makes it possible to grasp the amount of electric power that can be purchased at the possession points.

In step S404, the power purchase processing unit 467 determines the power purchase amount and the power purchase schedule (start date and time, period, etc.) according to the operation content on the power purchase operation screen. At this time, the electric power purchase processing unit 467 causes the display unit to display an operation screen for determining the electric power purchase amount and the electric power purchase schedule via the display processing unit 462.

In step S406, the power purchase processing unit 467 transmits a power purchase request (an example of the first request signal) including the purchase amount and the purchase schedule to the DR management server 31 via the communication processing unit 461.

In step S408, the power purchase processing unit 467 starts power purchase according to the determined purchase schedule (start date and time), and uses power based on the power usage information received from the smart meter 41 through the communication processing unit 461. Monitor the amount.

In step S410, the power purchase processing unit 467 determines whether or not to continue the power purchase. For example, the electric power purchase processing unit 467 may determine whether or not to continue the electric power purchase depending on whether or not the period determined in the purchase schedule has elapsed. Further, for example, the electric power purchase processing unit 467 may determine whether or not to continue the electric power purchase depending on whether or not the operation for forcibly terminating the electric power purchase is performed on the electric power purchase operation screen. The electric power purchase processing unit 467 repeats the process of this step when continuing the electric power purchase, and proceeds to step S412 when the electric power purchase is not continued.

In step S412, the electric power purchase processing unit 467 ends the electric power purchase, and determines the electric power purchase amount based on the electric power usage amount information received from the smart meter 41 through the communication processing unit 461. For example, if the amount of electricity used during the electricity purchase period is equal to or greater than the current point electricity conversion value, the amount of electricity purchased by the possessed points is the amount of electricity that can be purchased using all the possessed points (corresponding to the point electricity equivalent value). The points that are determined and associated with the identification information of the customer 4 disappear, and the possession points become zero. On the other hand, if the amount of electricity used during the electricity purchase period is smaller than the current point power conversion value, the amount of electricity purchased is determined by the amount of electricity used during that period, and points associated with the identification information of the consumer 4 are given. The number of points possessed decreases according to the amount of electricity purchased, in a manner in which the elapsed time from the longest is eliminated.

In step S414, the power purchase processing unit 467 transmits a power purchase end notification including information on the power purchase amount by using the possession points to the DR management server 31 via the communication processing unit 461. As a result, the information regarding the amount of power purchased by using the possessed points is transferred from the DR management server 31 to the power supply company 2 (power supply management server 21) as described above, so that the amount of power purchased by using the possessed points is transferred. Can be subtracted from the usage fee of the consumer 4. That is, the consumer 4 can indirectly purchase electric power with points.

The electric power purchase processing unit 467 may directly transmit information regarding the amount of electric power purchased by using the possession points to the electric power supply company 2 (electric power supply management server 21) through the communication processing unit 461.

As described above, in the demand response system 1 according to the present embodiment, the mobile terminal 46 possessed by each of the plurality of consumers 4 is the power reduction amount calculation unit 464 that calculates the power reduction amount of each of the plurality of consumers 4. And, according to the amount of power reduction for each of the plurality of consumers 4, points that can be used as the power purchase cost are given in a manner corresponding to the identification information (user ID, etc.) defined for each of the plurality of customers 4. A point giving portion 465 is provided. In other words, in the demand response system 1 according to the present embodiment, the mobile terminal 46 (demand response execution processing unit 463) has a power reduction amount calculation step for calculating the power reduction amount of each of the plurality of consumers 4, and a mobile device.

It is provided with a power purchase support processing unit 314 that performs processing that pretends that a part of the generated power has been purchased with points. As a result, each consumer 4 can specifically purchase electricity by using the points.

Further, in the present embodiment, the points given by the point giving unit 465 in a manner corresponding to the identification information of the customer 4 become zero in value after a predetermined period of time has passed since the points were given. As a result, the user (customer 4) tries to use the points as soon as possible, so that indirect power trading by using the points can be further promoted.

Further, in the present embodiment, the value of the points given by the point giving unit 465 in a manner corresponding to the identification information of the customer 4 decreases with the passage of time. As a result, the user (customer 4) tries to use the points as soon as possible, so that indirect power trading by using the points can be further promoted.

Further, in the present embodiment, the points given by the point giving unit 465 in a manner corresponding to the identification information of the customer 4 are valued according to the time zone of the day and at least one of the seasons of the year. Changes. As a result, the user (customer 4) is motivated to use the points in a state where the value is relatively high, and indirect power trading by using the points can be promoted.

Further, in the present embodiment, the DR management server 31 includes a communication processing unit 311 (third transmission unit) that transmits a DR request to the mobile terminal 46, and the mobile terminal 46 requests a DR from the DR management server 31. A communication processing unit 461 (third receiving unit) that receives the above, and a DR execution processing unit 463 that reduces the power consumption of the consumer 4 based on the DR request received by the communication processing unit 461. As a result, each consumer 4 can execute a demand response that reduces power consumption in response to a DR request transmitted from the DR management server 31, and acquires points according to the execution of the demand response. Therefore, the demand response can be effectively promoted.
