Description

  The present invention relates to a power saving determination system and a power saving determination method for determining whether or not power saving has been achieved based on measurement of power consumption of a consumer and recognition of behavior of a customer member.

  On hot days in summer, ordinary people stop outside their air conditioners (hereinafter referred to as “air conditioners”) and go out to gather in cool places such as commercial facilities and public facilities. There is known a power saving method for reducing power consumption in a general household. Such a power saving method is called “cool share”. Currently, national organizations, local public organizations, electric power companies, etc. are conducting public relations activities through various media and calling for participation in cool shares for ordinary households.

  In addition to the above-mentioned call, in order to realize participation of many people in ordinary households in the cool share, some method or system for strengthening incentives for ordinary household people to participate in the cool share is necessary. Conceivable.

  In this regard, Patent Document 1 discloses the following method. That is, according to the description of this gazette, the power company wants customers to cooperate in power saving (power saving) by e-mail, the time zone in which they want to cooperate in power saving, and a specific restaurant in that time zone If you make a reservation for a meal, etc., you will be notified that you will receive a special treatment service at the restaurant, etc., and in response, two or more of the members of the customer will make a reservation at the restaurant, etc. If the user goes out to eat at the restaurant or the like during the time zone specified in (1), the amount of power used by the customer during that time zone is reduced, and power saving is realized.

  The browsing PC 9 is a general personal computer owned by, for example, a customer, and is provided in, for example, a customer's home. The browsing PC 9 is connected to the Internet, for example. The member of the consumer can access the web server 8 using the browsing PC 9 and browse the web page for notifying the above-mentioned designated time and designated location. A terminal device such as a smartphone can be used instead of the browsing PC 9.

  Hereinafter, the power saving determination process performed by the power saving determination system 1 having such a configuration will be described with reference to FIGS. 2 to 5. For convenience of explanation, the power saving determination process is divided into a power usage measurement / recording process, a visit information generation process, and a determination process.

  FIG. 2 shows the power consumption measurement / recording process. The power consumption measurement / recording process is a process related to the measurement of the power consumption by the smart meter 2 and the recording of the power consumption by the power consumption recording device 6. In the power usage measurement / recording process shown in FIG. 2, first, the smart meter 2 measures the power usage of the consumer (step S11). Subsequently, the smart meter 2 generates measurement information including the identification information of the smart meter 2, the power usage information indicating the power usage amount of the consumer, and the measurement time information indicating the measurement time. (Step S12).

  Subsequently, the power amount recording device 6 receives the measurement information transmitted from the smart meter 2 (step S13). Subsequently, the power amount recording device 6 extracts identification information, power usage amount information, and measurement time information of the smart meter 2 from the received measurement information. And the electric energy recording apparatus 6 records electric power consumption information with a measurement time information on a recording medium about the consumer specified by the identification information of the smart meter 2 (step S14). The processes in steps S11 to S14 are repeated every predetermined time (for example, 30 minutes).

  FIG. 3 shows the visit information generation process. The visit information generation process is a process related to reading of information from the IC card 3 by the card reader 4, generation of visit information, and transmission of visit information by the communication PC 5.

Here, the premise of the visit information generation process will be described first. That is, the consumer member has received the IC card 3 from the system administrator in advance. Further, a member of the consumer operates the browsing PC 9 to access the web server 8 and browses a web page published by the system administrator. For example, the following items are described in the web page.
(1) To request cooperation for power saving (2) Designated time (3) Designated location (4) Go to the designated location at the designated time, and let the card reader read the information on the IC card at the time of payment for product purchase Receiving power saving judgment (5) Stopping the air conditioner at the customer's house when going out, and rewarding accordingly when power saving is achieved

FIG. 4 shows an example of a web page.
The member of the consumer who browsed the web page and formed an incentive for power saving brings out the IC card 3 to go to the designated place at the designated time. Before leaving the customer's home, the customer's members stop electrical devices that consume a relatively large amount of power, such as an air conditioner at the customer's home, and do not need to be in operation while they are out. Stopping such electrical equipment while going out greatly reduces the amount of electricity consumed by the consumer while going out, and as a result, it will be possible to obtain rewards (points). Can be easily recognized. This recognition is considered to contribute to the formation of a reliable incentive to realize power saving. And the member of the consumer who went out goes to the counter of the said department store in order to purchase goods in the department store which is a designated place, and to make a payment.

  This completes the description of the preconditions for the visit information generation process. Next, the contents of the visit information generation process will be described. In FIG. 3, when a consumer member approaches the IC card 3 or makes contact with the card reader 4 when making a payment for the purchased product at the register counter of the department store as the designated place, the card reader 4 Is detected (step S21: YES). Subsequently, the card reader 4 reads the identification information of the IC card 3 from the information storage element of the IC card 3 (step S22). Subsequently, the card reader 4 generates visit information and outputs the generated visit information to the communication PC 5 (step S23). The card reader 4 generates the visit information as follows. That is, as described above, the visit information includes the identification information of the IC card 3, the reading time information, and the identification information of the card reader 4. The identification information of the IC card 3 is acquired by reading from the IC card 3. The reading time information is information indicating the time when the card reader 4 reads the identification information from the IC card 3, and this is generated by the time measuring function of the card reader 4. Since the identification information of the card reader 4 is stored, for example, in a storage element built in the card reader 4, it is obtained by reading from the storage element.

  Subsequently, the communication PC 5 that has received the visit information from the card reader 4 transmits the visit information to the determination server 7 provided in the management center (step S24). Subsequently, the determination server 7 receives the visit information transmitted from the communication PC 5, and temporarily stores the received visit information in a storage device provided in the determination server 7 (step S25).

  FIG. 5 shows the determination process. The determination process is a process related to determination of a decrease in consumer power consumption caused by the going out of customer members, which is performed by the determination server 7. The determination process is performed in a time zone where the amount of power used is small, for example, at midnight, when the power system as a whole is viewed. The determination process is performed, for example, in the first midnight time zone after the new visit information is stored in the storage device of the determination server 7. In the determination process shown in FIG. 5, the determination server 7 first reads new visit information from the storage device provided in the determination server 7 (step S31).

  Subsequently, the determination server 7 extracts the identification information of the IC card 3, the identification information of the card reader 4, and the reading time information from the visit information, and identifies the customer who has visited the designated place based on the identification information of the IC card 3. The specified place is specified based on the identification information of the card reader 4 (step S32). That is, step S32 is processing assuming that there are a plurality of consumers and a plurality of designated places. That is, based on the identification information of the IC card 3, one consumer to be processed is specified from among a plurality of consumers. In addition, based on the identification information of the card reader 4, one designated place to be processed is specified from among a plurality of designated places. The following description of steps S33 to S38 will be made for a case where processing is performed for the customer and the specified place specified in step S32.

Subsequently, the determination server 7 acquires the specified time information by reading from the storage device provided in the determination server 7 (step S33).
Subsequently, the determination server 7 determines whether or not a member of the customer has visited the specified place at the specified time (step S34). Specifically, the determination server 7 compares the read time information extracted from the visit information in step S32 with the specified time information acquired in step S33, and the time indicated by the read time information is within the specified time range. Determine whether or not.

  When the time indicated by the reading time information is within the range of the specified time (step S34: YES), the determination server 7 subsequently acquires information indicating the power usage amount of the consumer from the power amount recording device 6. (Step S35). Specifically, the determination server 7 transmits information for identifying a consumer (for example, identification information of the IC card 3) and specified time information to the power amount recording device 6, and visits the power amount recording device 6. Request is made to transmit the power usage information of the consumer at the specified time of the day and the power usage information of the consumer at a predetermined time of the past day. In response to this, the power amount recording device 6 identifies the consumer based on the information received from the determination server 7 for identifying the consumer. Further, the power amount recording device 6 searches the recording medium of the power amount recording device 6 based on the designated time information received from the determination server 7 and the measurement time information recorded on the recording medium of the power amount recording device 6. Then, the power usage information of the customer at the designated time on the day of the visit and the power usage information of the customer at a predetermined time (described in detail later) in the past are acquired. Subsequently, the power consumption recording device 6 stores the power usage information of the customer at the specified time on the day of the visit and the power usage information of the customer at the predetermined time in the past on the recording medium of the power consumption recording device 6. Are transmitted to the determination server 7, and the determination server 7 receives them.

  Subsequently, the determination server 7 calculates an average value of the power usage amount of the customer at the designated time on the day of arrival based on the power usage information of the customer at the designated time on the day of arrival. Further, the determination server 7 calculates an average value of the power usage amount of the customer for a predetermined time in the past day based on the power usage amount information of the customer for a predetermined time of the past day. Then, the determination server 7 reduces the average value of the power consumption of the customer at the designated time on the day of the visit (hereinafter referred to as “power” "Usage reduction rate"). Subsequently, the determination server 7 determines whether or not the calculated power consumption reduction rate has reached a predetermined reference value (step S36).

When the calculated power consumption reduction rate has reached a predetermined reference value (step S36: YES), the determination server 7 has gone out to go to the designated place at the designated time by the consumer member. Thus, it is determined that power saving has been achieved (step S37).
On the other hand, when the time indicated by the reading time information is not within the range of the specified time (step S34: NO), or when the power consumption reduction rate does not reach the predetermined reference value (step S36: NO), the determination is made. The server 7 determines that power saving has not been achieved (step S38).

  Here, the power consumption of the customer at a predetermined time on the past day is, for example, the customer's power consumption at the same time as the designated time on the same day as the day of visit in the past several years (for example, 3 to 5 years). Electricity consumption. Note that the power usage amount of the consumer at a predetermined time in the past day may be, for example, the power usage amount of the customer at the same time as the specified time for several days before the visit day. Also, instead of the customer's power usage at a predetermined time in the past, for example, the customer's power usage for several hours before the designated time on the day of visit and for several hours after the designated time on the day of visit may be used. Good. Further, instead of the power usage amount of the consumer at a predetermined time in the past day, for example, an average value of the power usage amounts of a plurality of other consumers at the specified time on the day of the visit may be used.

  Further, the system administrator performs the following several tasks related to the execution of the power saving determination process by the power saving determination system 1.

  First, the IC card 3 is given to a consumer who has signed an electricity supply and demand contract. You may make it distribute IC card 3 to all the consumers who have concluded the electric power supply and demand contract, and the power saving judgment by the power saving judgment system 1 among all the consumers who have concluded the electric power supply and demand contract The IC card 3 may be handed over only to a customer who wants to receive it.

  Secondly, some reward is given to the consumer determined to have achieved power saving in the determination process (FIG. 5). For example, 1 point is given to a consumer who has been determined to achieve power saving by visiting a designated place at a designated time. The customer who has accumulated 10 points is given the right to exchange points for goods and the right to receive discounts on electricity charges.

  Third, in order to set a facility or the like as a designated place, a business tie-up contract is concluded with the manager or the like of the facility, and for example, the installation or the like of the card reader 4 is requested to the manager or the like of the facility. In addition, the number of customer members (number of customers) who visited the facility set as the designated place at the designated time is counted based on the visit information, and when this number reaches the predetermined number, You may make it give a certain profit (for example, the right etc. which receive the discount of an electricity bill) etc. to the manager of a facility.

  As described above, according to the power saving judgment system 1, the member of the customer has gone to the designated place at the designated time, and the power usage amount of the consumer at the designated time has decreased to a level below a predetermined standard. Achievement of power saving is recognized and the consumer is rewarded. Thereby, not only an incentive to go out, but also an incentive to reduce the amount of electric power used by the customer who is going out by stopping the air conditioner in the customer's house while going out. As a result, the certainty of realization of power saving in the consumer is increased.

  For example, a customer member who has created an incentive to reduce the amount of electricity consumed by a customer at a specified time by going out will stop the air conditioners, etc. in all the rooms of the customer home before going out. All the customers will go out to stop the air conditioners etc. in all rooms. As a result, the power consumption of the consumer can be greatly reduced during the specified time. If many customers take such actions at the same time during the specified time, significant power savings can be realized.

  Moreover, the facility side which sells goods or provides a service can also obtain a profit by a customer member going to the facility etc. which are designated places, shopping, or receiving provision of a service.

  Further, the IC card 3 and the card reader 4 recognize that the consumer member has gone to the designated place, measure the power usage of the consumer with the smart meter 2, and record the measurement result in the power recording device 6 To record the information required to determine whether or not power saving has been achieved by placing a large burden on any of the consumer members, facility managers / workers, power company workers, etc. It can be collected easily. Further, by using the smart meter 2, information indicating the power usage amount of the consumer can be acquired at a short time interval such as 30 minutes, so that the demand at a short designated time such as 12:00 to 15:00, for example. Information indicating the power usage amount of the house can be acquired, and the reduction rate of the power usage amount of the consumer at the specified time can be accurately calculated using this information.

  In the power saving determination system 1 described above, the following modifications or alternative configurations can be adopted.

  First, in the power saving determination system 1, the following alternative configuration can be adopted as a configuration for recognizing the visit to the designated place at the designated time of the customer member using the IC card 3. That is, in the power saving determination system 1 described above, for example, the card reader 4 is placed on a cash register counter of a department store which is a designated place, and the card reader 4 uses the card reader 4 to identify the identification information of the IC card 3 at the time of settlement of a product purchased by a consumer member. Based on the reading time information indicating the reading time of the IC card 3 obtained at this time and read from the IC card 3, it is recognized that the customer member has gone to the designated place at the designated time. Instead of this configuration, for example, when the card reader 4 is placed at the entrance / exit of a department store, which is a designated location, and the customer member enters or exits the department store, the card reader 4 uses the card reader 4 to identify the IC card 3 identification information. 3, based on the reading time information indicating the reading time of the IC card 3 obtained at this time, it may be recognized that the customer member has gone to the specified place at the specified time. This configuration is suitable when a place such as a leisure facility where no settlement is assumed is set as the designated place, or when a transportation facility such as a train or a subway is set as the designated place.

  Moreover, in the power saving determination system 1, the following alternative configurations can be adopted for the configuration relating to the restriction of consumers that are the targets of the power saving determination. That is, in the power saving determination system 1 described above, all customers who have received the IC card 3 from the system administrator are the targets of the power saving determination. Instead of this configuration, when requesting cooperation of power saving by displaying the designated time and designated place on the web page provided by the web server 8, a prior declaration of going to the designated place at the designated time is given. It is good also as a structure which asks a consumer. Specifically, on the web page provided by the web server 8, in addition to displaying the designated time and designated place, a form for inputting advance report information that can identify a consumer such as an electricity supply and demand contract number And a button for sending advance report information. A member of a customer who wants to go to a specified time and a specified location operates the browsing PC 9 to access the web page, inputs pre-report information into the form, and presses the send button (click (Or tap), the prior report information is transmitted from the browsing PC 9 to the web server 8, and further transmitted from the web server 8 to the determination server 7. Then, in the determination process, the determination server 7 identifies the consumer who made the preliminary report based on the prior report information, and sets the consumer as a target for the power saving determination.

  Moreover, in the power saving determination system 1 described above, the designated time and designated place are transmitted to the consumer by the web page provided by the web server 8, but instead, the designated time and designated place are electronically transmitted. It may be communicated to customers by email.

  In addition, the above-described power saving determination system 1 sets a time when the power demand in summer is expected to reach a peak as a specified time, and prompts the user to go to a specified place (for example, a cool share spot) at the specified time. However, this is not a limitation, and the designated time is set as the time when power demand is expected to increase in winter and other periods, or when power supply is expected to be insufficient. It may be urged to go to a designated place at the designated time.
