Description

  The present invention provides a power supply service providing system for buying and selling equipment usage rights and controlling individual consumer side equipment so that a cost merit can be obtained between the aggregate consumer and the individual consumer supplying the purchased power. It is about.

  Conventionally, the power supply / demand balance between the power supply amount and the power consumption amount is maintained, and the amount paid for the power supply / demand imbalance on the day is reduced (for example, see Patent Document 1). In this system, the power supply / demand imbalance is suppressed by adjusting at least one of the power supply amount and the power consumption amount, and the amount paid to the power supplier is reduced.

  In addition, when a power consumer makes a power purchase contract with a power supplier, it can respond by changing the power purchase plan for the next month, the power purchase plan for the next day, and the power purchase plan a few hours later on the day at the shortest. (For example, refer to Patent Document 2). In this system, the change of conditions is not allowed after the final change, and the one-on-one transaction between the customer and the power supplier is clarified by the restriction of this time zone.

  Next, the operation of the power supply service providing system according to the first embodiment will be described with reference to the drawings.

  FIG. 3 is a diagram for explaining a right to use a device of the power supply service providing system according to Embodiment 1 of the present invention. In the figure, “R” in circles represents the right to use the device, and “M” in circles represents an integrated watt-hour meter.

  In FIG. 3, the power supplier supplies power to the aggregate consumer and does not directly supply power to the individual consumers A, B, and C. The aggregate consumer supplies power to the individual consumers A, B, and C. The individual consumers A, B, and C pay a power usage fee to the aggregate customer, and the aggregate customer pays a power usage fee to the power supplier.

  The individual customer A has a device usage right U1 that can be bought and sold that is linked to the device 12 that the individual customer A owns, and buys and sells the device usage right U1 with the aggregated customer. The individual customer B also has the device usage rights U2 and U3 that can be bought and sold linked to the devices 22 and 23 that the individual customer B owns, and buys and sells the device usage rights U2 and U3 with the aggregated customer. Similarly, the individual customer C has a device usage right U4 that can be bought and sold, which is linked to the device 32 that the individual customer C owns, and buys and sells the device usage right U4 with the aggregated customer. The aggregate customer can control the devices 12, 22, 23, and 32 linked to the device usage rights U1 to U4 purchased from the individual customers A, B, and C by the server 100, and the power consumption of the entire individual customer The amount can be suppressed.

  FIG. 4 is a diagram showing a device usage right trading display table displayed on the controller of the power supply service providing system according to Embodiment 1 of the present invention. In FIG. 4, the period from 00:00 to 01:00, the period from 10:00 to 13:30, and the period from 23:00 to 24:00 (00:00) are set as the device usage right. The case of being a target is shown, and a time zone of 30 minutes is expressed at the end of the period. For example, “00:30” means a 30-minute time slot from 00:00 to 00:30. In FIG. 4, each time slot is displayed so that the difference in the status of the device usage right can be understood. In this embodiment, the time zone as a processing unit is set to 30 minutes, but is not limited to 30 minutes, and may be 15 minutes or 1 hour.

  In FIG. 4B, when the display space of the controller 20 is small and 24 hours cannot be displayed, the scroll function 20a may be used. The same applies to the controllers 10 and 30.

  FIG. 5 shows the server operation of the power supply service providing system according to Embodiment 1 of the present invention (device use right transfer processing on the day before control: device use right transfer means on the day before control) and the operation of the controller (device use on the day before control). It is a flowchart which shows a right transfer process.

  Since a large number of air conditioners (air conditioners) are installed and the overall power consumption can be suppressed by controlling the air conditioners, the air conditioners will be mainly described as the devices.

  In step S201, the controller transmits bid information for the next day for each device to the server 100 for each device, for example, once a day by an operation of an individual consumer (in the following description, wireless or the like is also possible). The description about the communication medium is omitted, and it is simply described as transmitting or receiving.)

  The controller generates a device use right transfer price and a desired discount rate at the time of control as bid information. The device usage right transfer price includes an individual customer ID, a device ID, a date, a time zone, and a bid price. Further, the desired discount rate at the time of control is composed of an individual customer ID, a device ID, a date, a time zone, and a predetermined number of discount rates that determine the discount amount of the power usage fee when controlled. Each discount rate is determined for each suppressed amount of power that is determined discretely. When power consumption is suppressed by a predetermined amount, a charge obtained by reducing the power usage fee for the power consumption before suppression by a discount rate becomes the power usage fee for that time unit.

  The individual customer ID is information for identifying an individual customer. The device ID is information for identifying the device. The date is the date of the next day. The time zone indicates which 30 minute unit from 00:00 to 24:00. The bid price is a bid price (yen) for transferring the right to use the device. The discount rate will be described when the set temperature of the air conditioner is raised once or twice. When the set temperature is raised by 1 degree, the discount rate is 1, and when it is raised twice, the discount rate is 2. The discount rate 1 is, for example, 10%, the discount rate 2 is, for example, 20%, and the individual customers A, B, and C bid.

  The controllers 10, 20, and 30 exclude each device (Mi (i) from the one day (00: 0 to 24:00) of the next day except for a time zone that is not a device usage right setting target (not specifically described below). = 1 to 3)) device usage rights U1, U2, U4 every 30 minutes (Tn (n = 1 to 11)) (00: 00 to 00:30, 00:30 to 01:00,...). Send bid price (yen).

  In step S <b> 101, for example, the server 100 obtains a predicted load value from a past actual load value and obtains a predicted operation value from a past actual operation value once a day.

  The server 100 calculates | requires load prediction value (Tn) (bar graph for every 30 minutes) using the past load actual value (Tn) which is not performing load control for every individual consumer. This predicted load value is the amount of power used (consumed) (kWh), and is determined in units of 30 minutes as the average of actual load values within a certain past period. In addition, for each device (Mi), an operation predicted value (Mi, Tn) is obtained by using past operation result values (Mi, Tn) that are not controlled. The predicted operation value is obtained in 30-minute units as an average of actual operation values within a fixed period in the past by a usage time rate (%).

  FIG. 6 is a diagram showing a target reduction power information table that is the power that the server should secure (reduce) for execution of control.

  As shown in FIG. 6, the server 100 stores information on power to be reduced for performing control in units of 30 minutes. The server 100 calculates the difference between the load target value (Tn) based on the contract power contracted with the power supplier and the maximum load predicted value (Tn) that is the total value of all the individual consumers of the load predicted value obtained above. The target reduction power corresponding to is calculated in units of 30 minutes, and the calculated results are collected and a target reduction power information table as shown in FIG. 6 is created and registered in the database. It should be noted that a target reduced power information table may be created in the subsequent step S102. For example, as shown in FIG. 6, focusing on the time zone 13: 0 to 13:30 means that the maximum load predicted value may exceed the load target value by 50 kW, and this may exceed 50 kW. As described later, the server 100 purchases the right to use the device.

  FIG. 7 is a diagram showing a controllable power table that summarizes controllable power of the devices managed by the server.

  As shown in FIG. 7, the server 100 stores information on power that can be reduced by controlling the device. The server 100 summarizes the power that can be reduced when the devices 12, 22, and 3 are controlled once or twice in advance, that is, the power consumption suppression effect, as shown in FIG. Effect) Create a table and register it in the database. For the same device, only one or two can be selected.

  Next, in step S <b> 102, the server 100 creates a predicted return fee table for purchase of the device usage right from the bid information and the predicted operation value. The right to use the device is purchased based on the predicted return charge table.

  First, the server 100 obtains a predicted return fee Pt (Mi, Tn) from the following formula from the bid information received from each controller and the predicted driving value. In this example, paying attention to a certain time zone, there are two discount rates for each device, so six predicted return charges Pt can be calculated in 3 × 2.

  Predicted reduction fee Pt (Mi, Tn) = reduction fee Pa (Mi, Tn) + predicted operation value (Mi, Tn) × reduction fee Pb (Mi, Tn)

  Here, the return charge Pa (Mi, Tn) is the bid price, and the return charge Pb (Mi, Tn) is Pb (Mi, Tn) = discount rate (Mi) × when the device operates without stopping the time unit. Standard power consumption kWh (converted value from power consumption kW) × electricity charge (unit price for each power consumption KWh). The reduction fee Pb (Mi, Tn) is obtained by another method except for the air conditioner. Since the predicted operation value is multiplied by the return fee Pb, the discount rate is obtained by multiplying the power usage fee when the device control is not performed by the discount rate, when the device control is actually performed. It is not necessary to multiply the predicted operation value. In this case, the discount rate is applied to the power usage fee determined by the power consumption suppression effect, which is the reduction fee when the device is actually controlled.

  FIG. 8 is a diagram showing an example of a predicted return charge table managed by the server of the power supply service providing system according to Embodiment 1 of the present invention.

  Next, the server 100 creates a predicted return charge table in which the value obtained by dividing the predicted return charge pt (Mi, Tn) by the power consumption suppression effect is arranged in ascending order and registers it in the database. The predicted return charge table in the time zone from 0:30 to 10:00 is as shown in FIG. The pre-discount charge is a portion of “standard power consumption Wh × electricity charge of the device” in the formula for calculating the return charge Pb (Mi, Tn). When the power consumption suppression effect is larger than the target reduction power, the target reduction power is set as the power consumption suppression effect. Next, the server 100 purchases device usage rights with lower unit prices in the order in which they are arranged in the predicted reduction fee until the total power consumption suppression effect of the purchased device usage rights exceeds the target reduced power. Note that each time a device usage right is purchased, the power consumption suppression effect and unit price are corrected, and the order of the device usage right in the predicted return charge table is also rearranged. Purchasing individual consumer C equipment (twice) results in a power consumption suppression effect of 20 kW or more of target reduction power, so purchase only individual consumer C equipment (twice) in the time zone from 0:30 to 1:00 To do. When deciding the device usage right to be purchased, the total of the purchase amount Pt is minimized in consideration of all combinations of the device usage rights to be purchased in which the total power consumption suppression effect is equal to or greater than the target reduction power. You may decide so. Any method may be used as long as the purchase price can be purchased so that the purchase price is within the allowable range from the minimum or the minimum.

  FIG. 9 is a diagram illustrating a selected device information table of devices for which the server has selected purchase of device usage rights.

  The server 100 uses the target reduction power information table, which is the power to be reduced for performing the control shown in FIG. 6, the above-described predicted return charge table, and the controllable power table shown in FIG. As shown, a device for which a device usage right is purchased is selected to create a selected device information table and register it in the database.

  The server 100 determines device usage rights to be purchased in the order listed in the predicted return charge table so that the total controllable power of the devices is equal to or greater than the target reduction power. For example, paying attention to the time zone 13: 0 to 13:30, if the target reduction power is 50 kW from FIG. 6 and the devices 12 and 32 are purchased in the order listed in the predicted return charge table, the controllable power from FIG. The total 50 kW (= 30 + 20) is equal to or greater than the target reduction power (50 kW). FIG. 9 shows a result of purchasing the device usage right. For example, when attention is paid to the time zone 13: 00 to 13:30, as shown in FIG. 9, the server 100 includes the devices 12 (A (12) (twice)), 32 (C (32) that have purchased the device usage right. ) (Twice)) is registered in the corresponding column of the selected device information table. Although details are omitted, the right to use the device is purchased in consideration of minimizing the purchase price.

  In addition, the server 100 transmits the purchase result of the device usage right to the controller. When attention is paid to the time zone 13: 0 to 13:30 from the selected device information table in FIG. 9, the controller 10 and 30 are notified that the device usage rights U1 and U4 have been purchased, respectively, and the controller 20 is also notified. The fact that the device usage right U2 has not been purchased is transmitted.

  FIG. 10 is a diagram illustrating a device usage right purchase price table of device usage rights purchased by the server. In FIG. 10, the time zones 10:00 to 10:30, 10:30 to 11:00 are omitted. For example, the device type A represents an air conditioner, and the device type B represents a water heater. Therefore, the device type A (1) (twice) of the individual consumer A corresponds to controlling the device 12 twice, and the device type A (1) (twice) of the individual customer C is the same as the device 12. This corresponds to controlling the type of air conditioner 32 twice.

  The server 100 obtains the device usage right purchase price table of FIG. 10 from the selected device information table of FIG. 9 and the device usage right transfer price (individual customer ID, device ID, date, time zone and bid price) of the bid information. Create and register in the database. When attention is paid to the time zone 13: 00 to 13:30, the server 100 selects the device 12 of the individual customer A, purchases the device usage right U1 of the device 12 at a bid price of 9 yen, and purchases the device as the purchase price. Register in the appropriate column of the usage right purchase price table. Similarly, the server 100 selects the device 32 of the individual customer C, purchases the device usage right U4 of this device 32 at a bid price of 15 yen, and registers it as the purchase price in the corresponding column of the device usage right purchase price table. To do.

  Next, in step S103, the server 100 selects the selected device information table in FIG. 9, the device usage right purchase price table in FIG. 10, and the desired discount rate (individual customer ID, device ID, date) when controlling bid information. From the time zone, the discount rate 1 and the discount rate 2), a priority order table for performing control is created for each time zone and registered in the database.

  FIG. 11 is a diagram showing a priority order table for performing control. In FIG. 11, a controllable device represents a controllable device. The power consumption suppression effect is retained as master data for each device. For example, in the case of an air conditioner, information indicating how much kW of energy saving can be expected when the set temperature of the cooling is increased by 1 degree (power consumption suppression (Expected value). This is a fixed value that can be obtained from the device catalog. The reduction fee is an operation predicted value (Mi, Tn) × reduction fee Pb (= discount rate (Mi) × standard power consumption Wh of device × electricity fee). Note that the discount rate here is the discount rate used in calculating the corresponding predicted return charge out of the discount rate 1 and the discount rate 2. The unit price calculation value is a unit price for realizing the energy saving effect of 1 kW, which is calculated by reduction fee / power consumption suppression effect. The priority order indicates the order from the smallest unit price calculation value.

  When attention is paid to the time zone 13: 0 to 13:30, the server 100 takes out the device 12 of the individual consumer A from the selected device information table of FIG. 9 as a controllable device. This device 12 corresponds to device type A (1). Next, a power consumption suppression effect, a reduction fee, and a unit price calculation value are obtained for the device 12. Similarly, the device 32 of the individual customer C is taken out, and the power consumption suppression effect, the reduction fee, and the unit price calculation value are obtained for this device 32. Then, as a priority order, the control unit is arranged in ascending order of unit price calculation values, and a priority order table of time zones 13: 0 to 13:30 as shown in FIG. 11 is created.

  In step S104, the server 100 registers the created priority table in the database as the next day plan.

  On the other hand, in step S <b> 202, the controller receives a device usage right purchase result from the server 100.

  FIG. 12 is a diagram for explaining the buying and selling of device usage rights in the power supply service providing system according to Embodiment 1 of the present invention.

  Through the exchange between the server 100 and the controllers 10 to 30 described above, as shown in FIG. 12, the aggregate consumer purchases the device usage rights U1 and U4 from the individual consumers A and C, and the individual consumers A and C hold them. The device 12 and 32 can be controlled, and the device usage right purchase price (bid price) (represented by a dotted line) is returned to the individual consumers A and C. In addition, the aggregate customer can purchase the device usage rights U1 and U4 to control the devices 12 and 32 of the individual consumers A and C, thereby suppressing the power consumption of the devices 12 and 32. The contract power with the power supplier can be kept low, and the fee paid to the power supplier can be reduced. The aggregate customer contracts with the power supplier as the contract power for the maximum power consumption (power consumption) for 30 minutes in the past year.

  FIG. 13 is a flowchart showing the server operation (load control processing: load control means) of the power supply service providing system according to Embodiment 1 of the present invention.

  In step S <b> 111, for example, the server 100 acquires the device operation results every 30 seconds and collects the load results from the watt-hour meter for each individual customer.

  The server 100 acquires an operation result value (date, time, device ID, ON / OFF, air conditioning set temperature, air conditioning setting mode, water heater reheating mode, etc.) from each device (Mi). Moreover, electric energy information (kWh / 30 seconds) is acquired from the integrated electric energy meters 11, 21, and 31 for each individual customer.

  Next, in step S112, the server 100 calculates whether control for load suppression is necessary from the actual load value and the predicted load value.

  The server 100 aggregates (adds) the power amount information for each individual consumer, and calculates the amount of power used per unit measurement period unit time (30 seconds). In addition, the total amount of power used was calculated, the total amount of power used (actual load value) for 30 minutes was calculated, and the actual load value exceeded the predicted load value compared to the predicted load value for the time period. If so, implement load control. The server 100 suppresses the difference when the actual load value exceeds the predicted load value by the load control.

  Next, in step S113, the server 100 determines whether control is necessary. If the actual load value exceeds the predicted load value, it is determined that control is necessary, and the process proceeds to the next step S114. If the actual load value does not exceed the predicted load value, it is determined that control is not necessary, and the process ends.

  Next, in step S114, the server 100 refers to the priority order table determined at the next day plan (previous day) time point.

  Next, in step S115, the server 100 performs control for each device having a high priority.

  The server 100 is set as a control target from a device with a higher rank until the difference between the calculated actual load value and the predicted load value becomes zero or less according to the priority table. The server 100 transmits a control command to the device that is the control target. Thereafter, the control execution information is registered in the database.

  The operation will be described by taking as an example a case where the difference between the actual load value and the predicted load value is 25 kW in the time zone 13: 0 to 13:30. The server 100 refers to the priority table in FIG. The server 100 transmits a control command for raising the set temperature twice to the device 32 of the individual customer C having the highest priority. Here, since the power consumption suppression effect when the set temperature of the device 32 of the individual customer C is raised twice is 20 kW, the difference does not reach zero. The priority order table after purchasing the device usage right to raise the device 32 of the individual customer C is as shown in FIG. 11B, and the power consumption suppression effect is more than the difference between the actual load value and the predicted load value. Since it becomes large, the power consumption suppression effect is set as the difference between the actual load value and the predicted load value. Then, since the unit price calculation value is minimized by raising the set temperature once for the device 12 of the individual consumer A, the server 100 raises the set temperature once for the device 12 of the individual consumer A. Send a control command. Thus, the difference can be reduced to zero or less. (The following is the same as the current situation.)

  In step S <b> 116, the server 100 transmits that the control is being performed to the controller during the control.

  When the server 100 transmits a control command for raising the set temperature once to the device 12 of the individual customer A, the server 100 transmits to the controller 10 that the device 12 is being controlled. Similarly, when a control command for increasing the set temperature once is transmitted to the device 32 of the individual customer C, it is transmitted to the controller 30 that the device 32 is being controlled. Note that the controller can access the control execution information in the database at an arbitrary timing to confirm the control execution information.

  FIG. 14 is a flowchart showing the server operation (device usage right repurchase processing: device usage right repurchase means) and the controller operation (device usage right repurchase processing) of the power supply service providing system according to Embodiment 1 of the present invention. It is.

  First, it is assumed that when load control is performed on the device by the server 100, the individual customer himself is performing an operation in a direction contrary to energy saving on the device. For example, it is assumed that an operation for lowering the set temperature is performed by an individual consumer after a control command for raising the set temperature is transmitted from the server 100 during the cooling operation of the air conditioner. If an operation in a direction contrary to energy saving is performed twice during the 30 minutes, it is considered that a repurchase request for the right to use the device has occurred.

  In step S <b> 121, the server 100 determines whether there is a request for repurchase of the right to use the device on the current day, for example, every 30 seconds. If there is a device usage right repurchase request, the process proceeds to the next step S122. If there is no device usage right repurchase request, the process ends.

  For example, the server 100 obtains an operation result value (date, time, device ID, ON / OFF, air conditioning set temperature, air conditioning setting mode, etc.) from each device (Mi) every 30 seconds, for example. On the other hand, when it is detected that the operation on the day in the direction opposite to the energy saving is performed twice in the 30 minutes, it is determined that there is a request for repurchase of the device usage right on the control day. The number of operations is not limited to two, and may be one or three or more times.

  Next, in step S122, the server 100 changes the priority order table for that day control.

  When there is a device usage right repurchase request, the server 100 controls the controllable device, power consumption suppression effect, reduction fee, unit price calculation value corresponding to the device usage right repurchase request from the priority order table used for the control of the day. , Delete priority. At this time, the priority order of the priority order table may be obtained again in ascending order of the unit price calculation value, or the substantial priority order does not change and may be left as it is.

  Next, in step S123, the server 100 calculates a device usage right repurchase penalty fee.

  The server 100 calculates a penalty fee for the individual consumer who owns the device for which the device usage right repurchase request has been generated, by the following formula. The penalty fee information is registered in the database.

  Penalty fee = device usage right purchase price (bid price) x α (α> 1.0)

  In step S124, the server 100 transmits penalty fee information to the controller.

  The controller can access the penalty fee information in the database at any timing to confirm the penalty fee information.

  The device usage right repurchase request button (hard button or soft button) may be provided in the controller. The operation of the controller in that case is as follows.

  In step S211, the controller determines whether there is a request for repurchase of the right to use the device on the current day, for example, every 30 seconds. If it is detected that the device usage right repurchase request button has been pressed, it is determined that there is a device usage right repurchase request, and the process proceeds to the next step S212. If there is no device usage right repurchase request, the process ends.

  Next, in step S212, the controller transmits the device usage right repurchase request of the day to the server 100 together with the device information.

  FIG. 15 is a diagram showing an operation when an individual consumer buys back a device usage right from an aggregate consumer in the power supply service providing system according to Embodiment 1 of the present invention. Note that FIG. 15 is merely an example of repurchase of the device usage right regardless of the previous and subsequent operations.

  Even if the individual customer has transferred the device usage right to the aggregated customer, but does not want to control the device for some reason, for example, he / she wants to control the device by sudden visitor etc. In such a case, the right to use the device can be bought back from the aggregate customer. However, aggregated consumers suffer from the risk of exceeding the contracted power due to a decrease in controllable equipment.Therefore, this amount can be charged to individual consumers as a penalty, and purchases at prices higher than the price at the time of purchase of equipment usage rights To be. By giving a penalty, the purchase of unnecessary equipment usage rights from individual customers is suppressed. In FIG. 4, the time zone 10:00 to 10:30 (crossed diagonal lines) of the device 22 indicates that the device usage right has been bought back. In FIG. 4, a satin portion with a dot is a place where the right to use the device is sold, and a place not drawn with hatching is a place where the right to use the device is not sold. One-sided diagonal lines indicate that control is being performed.

  FIG. 16 is a flowchart showing the server operation (fee calculation processing: fee calculation means) of the power supply service providing system according to Embodiment 1 of the present invention.

  In step S131, the server 100 sets a fee calculation processing period.

  The server 100 sets the fee calculation processing period, for example, as YYYY / MM / DD to YYYY / MM / DD in units of one month.

  Next, in step S132, the server 100 calculates a power usage fee from the contract content and the actual load value.

  For each individual customer, the server 100 calculates the initial power usage fee in the charge calculation processing period by the contract power unit price (yen / kWh) × the amount of power used (kWh).

  Next, in step S133, the server 100 calculates a return fee (incentive to individual consumers) for device usage right transfer and control execution to the device.

  For each individual customer, the server 100 obtains a return charge Pa (incentive) for the charge calculation processing period generated by the transfer of the device usage right and a return charge Pb (incentive) for the charge calculation process period generated by executing the control for the device. calculate.

  Next, in step S134, the server 100 calculates a penalty for repurchase of the device usage right.

  The server 100 calculates a penalty charge for the charge calculation processing period for the purchase of equipment usage rights for each individual customer.

  In step S135, the server 100 calculates the total power usage fee and transmits it to the controller.

  The server 100 calculates the total power usage fee for the charge calculation processing period from the following formula for each individual customer, and transmits it to the controllers 10, 20, 30.

  Total power usage fee = Electricity usage fee before correction-(Reduction fee Pa + Operation predicted value x Reduction fee Pb) + Penalty fee

  In addition, the server 100 registers, for each individual customer, the power usage fee before correction of the calculated fee calculation processing period, the reduction fee Pa, the reduction fee Pb, the penalty fee, and the total power usage fee in the database. The controller can access the charge information in the database at any timing for checking the charge information.

  FIG. 17 shows the operation of the server of the power supply service providing system according to Embodiment 1 of the present invention (device use right transfer processing on the control day: device use right transfer means on the control day) and the operation of the controller (device use on the control day). It is a flowchart which shows a right transfer process.

  In step S <b> 221, for example, the controller determines whether or not there is an operation for transferring the device usage right on the current day, for example, every 30 seconds. If there is an operation to transfer the device usage right, the process proceeds to the next step S222. If there is no device usage right transfer operation, the process ends.

  When an individual customer has a request to transfer a device usage right that was not transferred on the previous day, or when a bid for transfer of the previous day's device usage right is not purchased but wants to transfer the device usage right on that day For example, the right to use the device is selected by operating the controller.

  In step S <b> 222, the controller transmits to the server 100 bid information for transferring the device usage right on that day.

  The controller generates a device use right transfer price and a desired discount rate at the time of control as bid information. The device usage right transfer price is composed of individual customer ID, device ID, date, time zone, and bid price. When transferring the device usage right on the day, the bid price is not set, but the time zone to be transferred is set. To do.

  In step S <b> 141, for example, the server 100 determines whether or not there is transmission of bid information on the transfer of the device usage right of the day from the controller every 30 seconds. If there is bid information for transferring the device usage right on that day, the process proceeds to the next step S142. If there is no bid information for transferring the device usage right on that day, the process proceeds to step S143.

  Next, in step S142, the server 100 changes the priority table for the current day control.

  When the device usage right is transferred on the current day, the server 100 adds the controllable device to the priority table used for the current day control.

  FIG. 18 is a diagram showing a device usage right purchase price table using the previous day's purchase price information for determining the device usage right purchase price on the control day in the first embodiment of the present invention.

  In FIG. 18, (a) is a device usage right purchase price table on the day before control, (b) is a device usage right sale request (transfer request) table on the control day, and (c) is a device usage right purchase price added on the control day. Each table is shown. The device type A (1) of the individual customer B indicates that the bid is made but the purchase cannot be made, and the device usage right on the day is transferred (sold). In addition, the device type A (1) of the individual consumers D and E (not shown in FIG. 1) indicates that the device usage right on that day is to be transferred (sold) although it has not been bid from the beginning.

  As shown in FIG. 18, when bid information on sale of device usage rights is transmitted from the controller on the day of control to the price of device usage rights purchased as of the previous day, the server 100 sends another controller on the previous day. Purchase the right to use the equipment at a price lower than the minimum price purchased from. As shown in FIG. 18 (c), purchase is made at a price of 50% of the lowest price of the previous day on the day of control.

  When paying attention to the time zone 13: 00 to 13:30, the lowest price of the device usage right purchase price on the previous day shown in FIG. Further, when paying attention to the time zone 23: 00 to 23:30, since the lowest price of the device usage right purchase price on the previous day shown in FIG.

  19, (a) is the device usage right purchase price table of the previous day, (b) is the device usage right sale request (transfer request) table on the day of control, (c) is the device usage right purchase price table of the day before, (D) shows a device usage right purchase price table added on the day of control.

  As shown in FIG. 19, when the bid information for selling the device usage right is transmitted from the controller on the day of control, the server 100 purchases the device usage right at a price lower than the lowest price purchased from the other controller on the previous day. If an attempt is made to purchase a device usage right at a time lower than that price, the purchase of the device usage right in that time zone is searched and the purchase of the device usage right is retrieved.

  As shown in FIG. 19 (a), the time zone of 12:30 to 13:00 and 13: 0 to 13:30 on the previous day has no purchase record of device usage rights, and as shown in FIG. Since there was a purchase record in the time zone going back every day, the purchase is made at a price of 50% of the minimum purchase price at that time. If attention is paid to the time zone 12:30 to 13:00, since the minimum price of the device usage right purchase price on the day before shown in FIG. Further, when paying attention to the time zone 13: 00 to 13:30, since the minimum price of the device usage right purchase price the day before the one shown in FIG.

  FIG. 20 is a diagram showing a device usage right purchase price table using the purchase price information of the previous day, two days before, and the initial value for determining the device usage right purchase price on the control day in the first embodiment of the present invention. is there.

  20, (a) is the device usage right purchase price table on the previous day, (b) is the device usage right sale request (transfer request) table on the control day, (c) is the device usage right purchase price table on the previous day, (D) shows the device usage right purchase price initial value table set by the server (aggregate customer), and (e) shows the device usage right purchase price table added on the control day.

  As shown in FIG. 20, the server 100 purchases the device usage right at a price lower than the minimum price purchased from the other controller on the previous day when the bid information on the sale of the device usage right is transmitted from the controller on the day of control. If there is no purchase during that time period, we will go back to the past and search for the actual purchase of equipment usage rights during that time period. If there is no, the device usage right is purchased at the price using the initial value set in advance by the aggregate customer.

  As shown in FIGS. 20 (a) and 20 (c), since there was no purchase record of the device usage right in the time zone 13:00 to 13:30 on the previous day and the day before the previous day, Purchase at the initial purchase price. If attention is paid to the time zone 13: 0 to 13:30, the initial purchase price of the device usage right for the device type A shown in FIG.

  FIG. 21 is a diagram showing a priority order table on the day before control and the day of control in Embodiment 1 of the present invention.

  In FIG. 21, (a) is a priority table (time zone 13: 00 to 13:30) determined on the day before control, and (b) is a priority table (time zone 13) determined after additional purchase of device usage rights on the control day. : 00 to 13:30). FIG. 21A is the same as FIG.

  As shown in FIG. 21 (a), the server 100 determines the priority order table for device control on the day before control, but as shown in FIG. 21 (b), purchases the device usage right on the day of control. In such a case, the controllable device is added to the priority order table. At that time, the server 100 adds the controllable device newly registered in the device usage right purchase price table of FIG. 18C, FIG. 19D, or FIG. Force the unit price calculation value. The unit price calculation value is set so that it is less than 50% of the minimum unit price calculation value among the unit price calculation values in the priority table on the day before control. The reduction fee is calculated from unit price calculated value × power consumption suppression effect.

  As shown in FIGS. 21A and 21B, the server 100 has, for example, a unit price calculation value 2.0 (yen) so that it is less than 50% of the minimum unit price calculation value 4.8 (yen / kW). / KW) is set. The unit price calculation values of the three controllable devices added to the priority table are set to the same value of 2.0 (yen / kW). Then, the server 100 rearranges the priorities in ascending order of the unit price calculation values. When the unit price calculation values are the same, priorities are determined in descending order of the power consumption suppression effect. Furthermore, when the power consumption suppression effect is the same, the priority order is determined in the order of the transfer of the device usage right on that day.

  Next, the operation (process) from step S143 to step S145 is the same as the operation (process) from step S113 to step S116 in FIG. Here, the actual load value and the predicted load value already obtained in the load control process and the priority order table of FIG. 21B are used.
