Description

  The present invention relates to a power demand adjustment system and a power demand adjustment device.

  In order to increase the operational efficiency of the power system, it is known to level the load. By shifting the peak of the demand for power consumption to another time zone, the power consumption can be leveled, and as a result, it is not necessary to increase the capacity of the power generation equipment and power transmission / distribution equipment.

  As a method for shifting the peak demand of power to another time zone, a rate plan (TOU: Time Of Use) that changes the electricity rate for each time zone has been introduced. In such a rate plan, an electricity charge is set high during a time period when the power demand is large, and an electricity charge is set cheaply during a time period when the power demand is small. As a result, power demand is induced from an expensive time zone to an inexpensive time zone.

  In recent years, a demand adjustment method called so-called demand response has also been proposed (Patent Document 1). In the demand response, the power demand is adjusted by a necessary amount when necessary based on the power demand state and the supply state. As a method for realizing the demand response, there are a method of finely adjusting an electric charge every hour, a method of paying an incentive to a consumer according to a demand adjustment amount, and a method of directly cutting off a load according to a prior contract content.

  In the prior art described in the above-mentioned document, in order to increase the reliability of demand adjustment, the power amount that can be adjusted by each consumer is collected in advance, and the adjustment that is allocated to each consumer based on the adjustable power amount Calculate the amount.

JP 2009-122485 A

  If the consumer side acts according to the requested power adjustment amount, the peak of power demand can be shifted. However, there is no guarantee that the customer side is aware of the demand for power demand adjustment, and the possibility that the customer side will act according to the request is not necessarily high. In the prior art, a demand adjustment request is made without taking into account any characteristics related to the behavior of each consumer, and therefore the possibility of realizing the request cannot be increased.

  Therefore, an object of the present invention is to provide a power demand adjustment system and a power demand adjustment device that can increase the response sensitivity of each consumer to demand adjustment information for adjusting power demand. Another object of the present invention is to grasp in advance the behavioral characteristics of each consumer based on the power consumption state of each consumer, and transmit demand adjustment information to each consumer according to the transmission conditions according to the behavioral characteristics of the consumer. An object of the present invention is to provide an electric power demand adjustment system and an electric power demand adjustment device that can be used.

  An example of the functional configuration of the demand adjustment server 100 is shown in FIG. Therefore, referring to FIG. 4, the demand adjustment server 100 includes, for example, a consumer behavior characteristic management unit 110, a customer DR preference table management unit 120, a demand adjustment request command generation unit 130, and a demand adjustment request command transmission. Unit 140 and communication unit 150.

  The consumer behavior characteristic management unit 110 corresponds to the consumer behavior characteristic management unit 1C shown in FIG. The consumer behavior characteristic management unit 110 provides each consumer with a plurality of behavior characteristics (for example, a blister compatible type, a troublesome type, a saving type, a comfort-oriented type, an information high sensitivity type, etc.). It is a function to set and manage any one from.

  The behavioral characteristics can be set manually by the customer himself / herself (user himself / herself), or can be automatically set by analyzing the history of power consumption data, or the behavioral characteristics that are automatically set Can also be changed manually by the user.

  In addition, although the case where only one behavior characteristic of a consumer is set is described, the structure which sets a some behavior characteristic with respect to the same consumer may be sufficient. When multiple behavior characteristics with different transmission conditions are set for the same consumer, for example, one of the transmission conditions is selected according to a predetermined criterion, or both transmission conditions are merged. In this case, a new transmission condition may be created.

  The customer DR preference table management unit 120 is an example of a “transmission condition management unit”, and corresponds to the customer DR preference table management unit 1D of FIG. The customer DR preference table management unit 120 includes the contents of the demand adjustment request command distributed to each customer and the transmission conditions (for example, distribution timing, distribution cycle, request granularity, adjustment target device, transmission means, etc.) ) Is set and managed.

  The transmission conditions can be set manually by the user, or can be automatically set according to the behavioral characteristics of the user (customer), or all or part of the automatically set transmission conditions. It can also be changed manually by the user.

  The demand adjustment request command generation unit 130 is an example of a “demand adjustment information generation unit”, and corresponds to the demand adjustment request command generation unit 1E illustrated in FIG. The demand adjustment request command generation unit 130 generates a command for requesting adjustment of power consumption at a consumer. The demand adjustment target value is input to the demand adjustment server 100 by an operator of the power system or the like. The demand adjustment server 100 generates a demand adjustment request command for each customer according to the demand adjustment target value. The demand adjustment amount is calculated for each consumer based on, for example, prior contract details or past power consumption.

  The demand adjustment request command transmission unit 140 is an example of a “demand adjustment information transmission unit”, and corresponds to the demand adjustment request command transmission unit 1F illustrated in FIG. The demand adjustment request command transmission unit 140 sends the demand adjustment request command generated for each consumer to each consumer so as to satisfy the transmission conditions defined in the customer DR preference table T14 (described later in FIG. 9). introduce.

  The communication unit 150 is a function for the demand adjustment server 100 to communicate with the other servers 110 to 140 and the customer side devices 200 to 202.

  Returning to FIG. 3, another configuration of the demand adjustment device 10 will be described. The demand value collection server 101 is an example of a “power consumption information collection unit”, and corresponds to the demand value collection unit 1A illustrated in FIG. The demand value collection server 101 has a function of acquiring data on the total power consumption of the consumer from the demand value management apparatus 202 via the communication network 40 and storing it in the consumer information server 103. The total power consumption data is data of the total power consumption (Wh) at the consumer at regular time intervals such as 1 minute, 15 minutes, and 30 minutes.

  The consumer information server 103 collects the contract related data of each consumer, the actual data of the electricity charges of each consumer, the actual data of the power consumption of each consumer, and the demand adjustment related data of each consumer. It is a device to manage according to. The contract related data includes, for example, a customer identification ID, a location, contract power, an applicable charge plan, and the like.

  The actual data of the electricity bill includes, for example, the total amount of electricity bill, the basic fee, the metered fee, etc. every month. The actual power consumption data includes, for example, actual value of total power consumption data at a consumer, data for each unit of power consumption (Wh) for each device, total monthly amount, and the like. The demand adjustment related data includes, for example, various management tables such as data of the DR preference table T14 of each consumer.

  The communication server 102 is a device that transmits and receives data to and from the consumer device monitoring control device 200 and the consumer input / output device 201 on the consumer side via the communication network 30.

  The apparatus configuration on the customer side will be described. On the consumer side, for example, a consumer device monitoring control device 200, a consumer input / output device 201, a demand value management device 202, and a plurality of electrical devices 21 to 26 are provided.

  The customer equipment monitoring control device 200 can constitute a “customer side management device” together with the customer input / output device 201 and the demand value management device 202. The consumer equipment monitoring control device 200 receives a demand adjustment request command from the demand adjustment server 100 installed on the utility provider side via the communication network 30. The consumer side management apparatus 200 switches ON / OFF of the electrical devices 21 to 26 on the consumer side or changes a set value (for example, temperature, operation time, etc.) according to the contents of the received command.

  Therefore, the consumer equipment monitoring control device 200 manages a demand adjustment control table (not shown), which is data associating the contents of the demand adjustment request command with the control contents of the consumer side electrical equipment. A consumer (specifically, a user of the consumer) sets a demand adjustment control table in advance via the consumer input / output device 201. The demand adjustment control table is control data for changing the set value of the electrical device according to the content of the command, such as turning off the air conditioner when receiving the demand adjustment request command.

  Moreover, the consumer equipment monitoring control apparatus 200 manages the operation state value and set value of the electrical equipment on the consumer side. The operating state value of each electric device on the consumer side is acquired by the consumer device monitoring control device 200 directly from each electric device or via a measuring device provided in each electric device, for example. .

  The user can output data managed by the consumer device monitoring control device 200 via the consumer input / output device 201.

  The customer input / output device 201 is a device for providing information to the user and receiving instructions from the user. The customer input / output device 201 displays, for example, data acquired from the customer device monitoring control device 200, or displays data acquired from the demand adjustment server 100 and the customer information server 103 via the communication network 30. To do. Furthermore, the customer input / output device 201 can also obtain an instruction from a customer (user).

  The consumer input / output device 201 can obtain, for example, the operation state value of each electrical device, the set value of each electrical device, the demand adjustment control table, and the like from the consumer device monitoring control device 200 and display them. Taking the air conditioner 24 as an example, the operating state values of each electric device include an ON / OFF state, power consumption, inlet temperature, outlet temperature, and the like. Examples of the set value of each electric device include a set temperature and a set air volume of the air conditioner 24.

  The customer input / output device 201 can also acquire and display a demand adjustment request command value (including the presence / absence of a demand adjustment command event, a demand adjustment target value, a demand adjustment period, etc.) from the demand adjustment server 100, for example. .

  The customer input / output device 201 can obtain, for example, contract related data, past actual values of electricity charges, past actual values of power consumption, demand adjustment related data, and the like from the customer information server 103 and display them. .

  The customer-related data includes, for example, the location of the customer, the amount of contracted electric power, an applicable fee plan, and the like. The past actual value of the electricity charge of the consumer includes, for example, the total monthly electricity charge, the basic charge, and the metered charge. The past actual value of the power consumption of the consumer includes, for example, the total power consumption, the power consumption for every fixed time for each electric device, the monthly power consumption, and the like. The demand adjustment related data of the consumer includes, for example, data of the DR preference table T14 related to the consumer, behavior characteristic data of the consumer, and the like.

  The customer input / output device 201 can also receive, for example, a correction instruction to the DR preference table T14, a correction instruction to the behavior characteristic data, a correction instruction to the demand adjustment control table, and the like from the consumer (user). The correction instruction (correction data) received from the consumer is written and reflected in a predetermined table.

  The demand value management apparatus 202 measures and manages the total power consumption (Wh) of a consumer at a constant time interval such as 1 minute, 15 minutes, and 30 minutes. The demand value management apparatus 202 outputs these data in response to a request from the demand value collection server 101.

  Since FIG. 4 has already been described, reference is made to FIG. FIG. 5 shows an example of the behavior characteristic priority management table T10. The behavior characteristic priority management table T <b> 10 is a table for managing the priority for each behavior characteristic, and is held in the power demand adjustment apparatus 10. Other tables described below are also held in the power demand adjustment apparatus 10.

  For example, the behavior characteristic priority management table T10 manages the behavior characteristic column C100 and the priority column C101 in association with each other. In this embodiment, examples of consumer behavior characteristics include a saving type, a comfort-oriented type, an information high sensitivity type, a blister type, and a troublesome type. Other behavioral characteristics may be added, or some of the behavioral characteristics listed as examples may be deleted.

  The saving type is a behavioral characteristic that tries to suppress power consumption as much as possible. Reducing users (users; the same applies hereinafter), for example, often see relatively many actions such as turning off the lighting frequently or setting the air conditioning temperature higher.

  The comfort-oriented type is a behavior characteristic that tries to maintain comfort even if the power consumption increases slightly. For example, a consumer who emphasizes comfort has a relatively large number of actions such as operating an air conditioner so that a comfortable room temperature can be obtained regardless of the outside air temperature.

  An information sensitive type is a behavioral characteristic that is highly motivated to collect information and has many activities for acquiring information. The information sensitive consumer has a relatively long time for operating a predetermined electric device such as a television. The predetermined electrical device is an information collection electrical device that has an electrical load that is useful for adjusting power demand, such as a television, and that is useful for collecting user information.

  The bean-responsive type is an action characteristic that responds delicately as needed. The diligent consumer has many actions such as frequent lighting ON / OFF operations or frequently changing the air-conditioning temperature. As a result, it often shows slightly similar behavior to the saving type, but the blame type does not make excessive savings because it responds as necessary.

  The troublesome type refers to a behavioral characteristic that often exhibits the opposite behavior to the blister type. For example, troublesome customers often see behavior such as not changing the air-conditioning temperature according to changes in the outside air temperature, or leaving the television or lighting turned on.

  In the present embodiment, the highest priority “1” is assigned to the blister-compatible type, the next highest priority “2” is set to the troublesome type, the priority “3” is set to the saving type, and the priority “3” is set to the comfort-oriented type. 4 ”is set in advance as the lowest priority“ 5 ”for the information high sensitivity type.

  In this embodiment, for example, the priority of behavior characteristics is set from the viewpoint of whether or not to act based on a demand adjustment request command. For example, since the bean correspondence type is considered to have a relatively high possibility of acting according to the demand adjustment request command, the highest priority is set. The troublesome type is likely not to follow the demand adjustment request directive, and cannot be relied on for demand adjustment. Since troublesome customers have low reliability in terms of demand adjustment, it is necessary to create a demand adjustment request command in consideration of low reliability. Therefore, a low priority is set for the troublesome type. Since the saving type takes consumption behavior with an emphasis on money, for example, if an appropriate incentive is set, it is considered that the demand adjustment request command is followed. Therefore, medium priority is set for the saving type. The reasons for setting priorities for other behavioral characteristics are omitted. However, the above priority setting method is merely an example, and is not limited to the example shown in FIG.

  The consumer behavior characteristic management unit 110 includes two means for setting the consumer behavior characteristic management table T11. One is manual setting means (not shown). The manual setting means can set the value of the behavior characteristic in the consumer behavior characteristic management table T11 according to the input from the user. The manual setting means can also be called a consumer behavior characteristic input setting unit.

  The other is means for automatically discriminating the behavioral characteristics of the consumer using the past data of the consumer's past power consumption data. This automatic discrimination means is shown, for example, as a consumer behavior characteristic determination unit 1B in FIG. 1, and as an automatic setting process flowchart of a consumer behavior characteristic management table in FIG.

  When the manual behavior characteristic setting and the automatic behavior characteristic setting conflict, the consumer behavior characteristic management unit 110 prioritizes the manual setting (user setting).

  FIG. 6 shows an example of a consumer behavior characteristic management table T11 for managing behavior characteristics for each consumer. The consumer ID column C110 stores an identifier for identifying each consumer in the power demand adjustment system. In the behavior characteristic column C111, behavior characteristics corresponding to each consumer are set. Although FIG. 6 shows a case where some customer characteristic is set for all customer IDs, there may be a consumer ID for which behavior characteristics are not set.

  FIG. 7 shows an example of the behavior characteristic determination rule management table T12. Hereinafter, it may be referred to as a rule management table T12. The rule management table T12 manages rules for determining the behavioral characteristics of the consumer based on the history of the consumer's power consumption behavior. For example, the rule management table T12 manages the index column C120, the reference column C121, and the behavior characteristic column C122 in association with each other.

  The index column C120 stores an index used for classification of behavior characteristics. Examples of the index include power consumption fluctuation amount, air conditioning temperature characteristics, TV ON rate, and the like.

  The power consumption fluctuation amount is an average value of the amount of change in power consumption per fixed time. When the power consumption fluctuation amount value exceeds the threshold value (VP_U) set in advance in the reference field C121, it is determined that the customer is the “blister compatible type”. On the other hand, if the value of the power consumption fluctuation amount is below a predetermined threshold value (VP_L), it is determined that the customer is “troublesome”.

  The air-conditioning temperature characteristic is a value of a correlation coefficient between power consumption within a certain time and average temperature. If the value of the air-conditioning temperature characteristic exceeds a predetermined threshold value (RP_U), it is determined that the customer is “comfort-oriented”.

  The TV ON rate is the ratio of the time that the TV is turned on within a certain time. When the value of the TV ON rate exceeds a predetermined threshold value (ONTV_U), it is determined that the consumer is “information high sensitivity type”.

  FIG. 8 shows a customer DR preference reflection rule management table T13 which is an example of the “behavior characteristic-transmission condition management table”. Hereinafter, it may be referred to as a reflection rule management table T13. The reflection rule management table T13 is used to automatically create the customer DR preference table T14 based on the customer behavior characteristic management table T11.

  The reflection rule management table T13 manages, for example, the behavior characteristic column C130, the distribution timing column C131, and the transmission means column C132 in association with each other. The behavior characteristics described above are set in the behavior characteristics column C130. In the distribution timing column C131, information indicating the timing at which the demand adjustment request command is to be transmitted to the consumer is set. A means for transmitting the demand adjustment request command to the consumer is set in the transmission means C132.

  In the example of FIG. 8, when “diligent correspondence type” is set in the behavior characteristic column C130, “mail to mobile phone” is set in the transmission means column C132, and “60” is set in the delivery timing column C131. "Until minutes ago" is set.

  When “save type” is set in the behavior characteristic column C130, “call transmission to mobile phone” is set in the transmission means column C132, and “until 60 minutes before” is set in the delivery timing column C131. Has been.

  If “being troublesome” is set in the behavior characteristic column C130, “ambient display” is set in the transmission means column C132, and “until 18:00 one day before” is set in the delivery timing column C131. ing.

  In addition, among the items C141 to C146 of the customer DR preference table T14, predetermined default values are set for items having no item corresponding to the reflection rule management table T13.

  FIG. 9 shows an example of the customer DR preference table T14. The consumer DR preference table management unit 120 manages the conditions regarding the distribution contents and the transmission form of the demand adjustment request command to each consumer as the consumer DR preference table T14.

  The customer DR preference table T14 associates, for example, a customer ID column C141, a distribution timing column C142, a distribution cycle column C143, a requested granularity column C144, a target device column C145, and a transmission means column C146. to manage.

  As a transmission condition regarding the distribution contents and transmission form of the demand adjustment request command, for example, a distribution timing, a distribution cycle, a requested granularity, an adjustment target device, and a transmission unit will be described.

  The distribution timing is a condition related to the time at which the demand adjustment request command is distributed to the consumer, and is set with the start time of the time zone in which the demand adjustment is expected as a reference time. For example, the delivery timing is set in a format of “until Y hours before X days before the reference time” or “until Z minutes before the reference time”. If the time that is the reference for starting demand adjustment is 12:00 on a certain day, the delivery timing is set to “until 18:00 one day before” or “until 60 minutes before”. When the delivery timing has passed, the demand adjustment request command is not delivered to the consumer. That is, the delivery timing indicates the final time when the demand adjustment request command can be delivered to the consumer. The time for starting distribution will be described later.

  The distribution cycle is a condition regarding a time interval when the demand adjustment request command is repeatedly distributed. For example, when the distribution cycle is set to 1 hour, the demand adjustment request command is distributed to the consumers every hour until the time set in the distribution timing comes.

  The requested granularity is a condition regarding the resolution of the demand adjustment request command. Whether the demand adjustment request command is a level at which the total power consumption of the customer is expected to be adjusted (hereinafter referred to as the “customer total adjustment level”), or specific electrical equipment of the customer (air conditioner, electric water heater, etc.) The adjustment of the expected power consumption level (hereinafter referred to as device-specific adjustment level) is shown. In FIG. 9, when “total” is set in the requested granularity column C144, it indicates the consumer total adjustment level, and when “by device” is set, it is the adjustment level by device. Indicates.

  Although not shown in FIG. 9, a column for demand adjustment target values may be provided. The electric energy (target value) expected by the demand adjustment can be ranked in advance, and a value for selecting any one of the ranks can be set in the demand adjustment target value column. For example, a value indicating the selected rank may be displayed together in the requested granularity column, such as “Total 1” and “By Device 3”.

  The adjustment target device is a condition for designating an electric device that is a target of demand adjustment. In the target device column C145, information for specifying an electrical device to be adjusted is set when “by device” is set as the requested granularity.

  In FIG. 9, the target device column C145 is shown as if a single electric device is set, such as “air conditioner” or “water heater”. However, in practice, a plurality of electrical devices can be set together with their priorities, such as “air conditioner 1, water heater 2, television 3”.

  It is also possible to designate the lowest priority of the device to be adjusted for each rank of the target value for demand adjustment. For example, when three ranks from rank 1 to rank 3 are prepared, “priority 1” is set for rank 3 with a small target value for demand adjustment. As a result, a consumer who is expected to adjust the power demand of rank 3 may stop only the air conditioner or change the set temperature in a specified time zone. In rank 1 where the target value for demand adjustment is large, “priority 3” is set. As a result, a consumer who is expected to adjust rank 3 adjusts not only the air conditioner 1 but also the operation of the water heater and the television. In other words, all electric devices up to the designated priority are subject to adjustment.

  The transmission means is a condition relating to specific means for distributing the demand adjustment request command to the consumer. Examples of the transmission means include e-mail to a personal computer, e-mail to a mobile phone, voice call to a mobile phone, facsimile communication, operation of an ambient display, and the like.

  Here, the ambient display is information output means that allows the user to passively sense information, such as lighting that automatically turns on and off in response to a signal input from the outside. Say.

  The customer DR preference table management unit 120 includes two means for setting the customer DR preference table T14. One is a means for a user to set manually, and can be called a consumer DR preference input setting unit. The other is means for automatically setting the value of each item of the customer DR preference table T14 by using the customer behavior characteristic management table T11 and the customer DR preference reflection rule management table T13. . This means can be called a behavior characteristic reflecting unit. When manual setting and automatic setting conflict, manual setting (user setting) has priority.

  The demand adjustment request command generation unit 130 generates a demand adjustment request command so as to satisfy both the demand adjustment target value and the transmission condition. The demand adjustment target value is given from another system outside the figure or an electric power system operator. The transmission conditions are defined in the customer DR preference table T14.

  The demand adjustment target value includes a target time zone for demand adjustment and a target power level adjustment level (target value level). The target time zone for demand adjustment can be defined by, for example, a start time (Ts) and an end time (Te). For example, start time (Ts) = June 1, 2011 13:00, end time (Te) = June 1, 2011 16:00. The target value level of the electric energy is a rank number corresponding to the target value for demand adjustment, as described above.

  The contents of the demand adjustment request command are the adjustment target device and the target adjustment level. In the target adjustment level, a value indicating the rank of the demand adjustment target value is set. For example, the value for specifying the device to be adjusted is set as follows.

(1) When the requested granularity value in the DR preference table T14 is set to give a customer total adjustment level, “customer total” is set as the value of the adjustment target device.

(2) When the requested granularity value in the DR preference table T14 is set to give the adjustment level of the specific device, the priority level of the target device in the DR preference table T14 is referred to and the target adjustment level value is set. The device type with the corresponding priority is extracted and set as the value of the target device.

  The distribution time Td [i] (i = 1, 2, N) of the demand adjustment request command to each consumer can be set as follows. In the following, the number of distributions is N.

(1) The value of the delivery timing in the DR preference table T14 is set to Y hours before X days before the reference time Ts.
As Td [1], “time Y at X days before Ts” is set.

(2) When the value of the delivery timing in the DR preference table T14 is set to Z minutes before the reference time Ts.
As Td [1], “Z minutes before Ts” is set.

(3) The repeated delivery time is set with reference to the value of the delivery cycle (Tinterval) in the DR preference table T14.
The time after the interval of Td [i] is set as Td [i + 1] (i = 1, 2,...).

  However, if the time of Td [i + 1] exceeds the end time Te, N = i and the setting of Td [i + 1] is cancelled.

  The demand adjustment request command transmission unit 140 distributes a demand adjustment request command generated for each consumer to each consumer by a method determined for each consumer.

  Although some operations have already been described, the outline of the operation of the power demand adjustment system will be described with reference to FIGS.

  FIG. 10 is a schematic flowchart showing the overall movement. First, the power demand adjustment apparatus 10 sets a consumer behavior characteristic management table T11 (S10). An example of step S10 will be described with reference to FIG.

  Next, the power demand adjustment apparatus 10 sets the consumer DR preference table T14 (S11). Since details of this step have already been described, further explanation will be omitted, but the power demand adjustment apparatus 10 can set the consumer DR preference table T14 according to user settings or automatically.

  Subsequently, the power demand adjustment apparatus 10 creates a demand adjustment request command for each consumer, and transmits those demand adjustment request commands to each consumer (S12). Step S12 will be described later with reference to FIG.

  FIG. 11 is a flowchart illustrating a process when the customer behavior characteristic management table is automatically set. The consumer behavior characteristic management unit 110 executes the following steps S21 to S27 for each consumer (S20). The consumer that is the target of this processing is called the target consumer.

  The consumer behavior characteristic management unit 110 acquires the power consumption data of the target consumer from the consumer information server 103 (S21). The consumer behavior characteristic management unit 110 executes the following steps S23 to S25 for each reference registered in the behavior characteristic determination rule management table T12 (S22). The standard for processing is called the target standard.

  The consumer behavior characteristic management unit 110 compares the target standard with the power consumption data of the target consumer (S23), and determines whether the target consumer satisfies the target standard (S24). When the target customer satisfies the target standard (S24: YES), the consumer behavior characteristic management unit 110 temporarily sets the behavior characteristic corresponding to the target standard as the behavior characteristic of the target consumer (S25).

  In this way, all the criteria described in the behavior characteristic determination rule management table T12 are applied to all consumers. As a result, at least one behavior characteristic is normally set for each consumer.

  The consumer behavior characteristic management unit 110 determines whether a plurality of behavior characteristics are set for one consumer. If a plurality of behavior characteristics are set, the priority described in the behavior characteristic priority management table T10. Accordingly, one of the behavioral characteristics having a higher priority is selected (S26).

  The consumer behavior characteristic management unit 110 registers the selected behavior characteristic as the consumer behavior characteristic in the consumer behavior characteristic management table T11 (S27).

  If the behavior characteristics matching the consumer's power consumption activity cannot be determined even after the processing shown in FIG. 11 is executed, the consumer behavior characteristic column C111 in the consumer behavior characteristic management table T11 indicates what Is not set. In this case, the consumer can manually set the behavior characteristics using the consumer input / output device 201. Even if the behavior characteristic is automatically determined, the consumer can manually change his / her behavior characteristic.

  FIG. 12 shows a process of creating a demand adjustment request command and transmitting it to the consumer. The demand adjustment request command generation unit 130 refers to the customer DR preference table T14 (S30), and determines whether there is a consumer who should transmit the demand adjustment request command (S31).

  When there is a customer who should transmit a command (S31: YES), demand adjustment request command generation part 130 generates a demand adjustment request command (S32). The demand adjustment request command generation unit 130 transmits a demand adjustment request command to the consumer using a preset transmission means for the consumer (S33).

  FIG. 13 shows processing for setting an electrical device on the consumer side. The consumer equipment monitoring control device 200 acquires the setting mode (S40). As described below, the setting mode includes a manual mode, a semi-automatic mode, and an automatic mode. The user can specify the setting mode in advance via the customer input / output device 201.

  When the setting mode is the manual mode (S41: YES), the consumer equipment monitoring control device 200 only displays the demand adjustment request command on the consumer input / output device 201 and does not set the electrical equipment (S42). In the manual mode, the user manually sets the electric device according to the demand adjustment request command.

  When the setting mode is the semi-automatic mode (S43: YES), the consumer equipment monitoring control device 200 displays a demand adjustment request command on the consumer input / output device 201, and automatically waits for consent from the user and automatically electrical equipment. (S44).

  When the setting mode is the automatic mode (S45: YES), the consumer equipment monitoring control device 200 automatically sets the electrical equipment according to the demand adjustment request command without obtaining the user's consent (S46).

  In this embodiment configured as described above, each customer can recognize the demand adjustment request command because the demand adjustment request command is transmitted to each customer under the transmission condition according to the behavioral characteristics of each customer. And the possibility to act in accordance with the demand adjustment request command. As a result, the power consumption can be adjusted at a high rate in each consumer, which can contribute to the leveling of power demand.

  In addition, this invention is not limited to the Example mentioned above. A person skilled in the art can make various additions and changes within the scope of the present invention.
