(Knowledge that became the basis of this disclosure)
This inventor discovered the subject regarding the power saving performed with respect to a power saving request | requirement. This will be specifically described below.

  FIG. 1 is a transition diagram showing a power saving flow in the reference example. FIG. 1 shows an electric power company, an aggregator, and a store. An electric power company is a company that sells electric power, and generates electric power, transmits power, and distributes electric power. The aggregator is an operator that mediates between an electric power company and a consumer, and manages electric power. For example, an aggregator urges consumers to save electricity and provides negawatts to an electric power company when power supply and demand is tight. A store is an example of a consumer and sells products. For example, the store is a convenience store or a supermarket.

  For example, the store periodically transmits power information indicating the power consumption to the aggregator. The aggregator receives power information periodically from the store.

  Then, the power company transmits a power saving request for the power saving period to the aggregator before the start of the power saving period. That is, a power saving request for the power saving period is issued. The power saving period is a period in which tightness of power supply and demand is expected. The aggregator receives a power saving request from the power company and transmits the power saving request to the store. The store receives a power saving request from the aggregator.

  In the store, power saving is performed during the power saving period based on the power saving request. During the power saving period, the store periodically transmits power information to the aggregator, and the aggregator periodically receives power information from the store.

  Then, after the end of the power saving period, the aggregator calculates a reward based on the power saving amount in the store. At this time, the aggregator calculates a reward based on the difference between the power consumption indicated by the power information received before the power saving request and the power consumption indicated by the power information received during the power saving period. More specifically, the aggregator calculates the baseline based on the power consumption before the power saving request, and calculates the reward based on the difference between the baseline and the power consumption during the power saving period. Then, the aggregator gives the calculated reward to the store.

  The difference between the power consumption before the start of the power saving period and the power consumption during the power saving period is assumed to be the power consumption reduced by the power saving, and is assumed to correspond to the power saving. However, by increasing the power consumption from the issuance of a power saving request to the start of the power saving period and returning the power consumption to the original value during the power saving period, the power saving amount is unreasonably increased and the reward is calculated high. Not appropriate. Therefore, for example, the aggregator calculates a reward based on the difference between the power consumption before the power saving request and the power consumption during the power saving period.

  FIG. 2 is a graph showing changes in power in the reference example. FIG. 2 shows the power of the refrigeration equipment, the power of other equipment, and the total power of the refrigeration equipment and other equipment. The refrigeration equipment is equipment for freezing or refrigeration, and may be a showcase for freezing or refrigeration, a refrigerator, a refrigerator, or the like. In particular, the refrigeration equipment performs a defrosting operation regularly or irregularly. The other device is a device different from the refrigeration device, such as an air conditioner.

  In this example, the baseline is calculated based on the power consumption in the period immediately before the power saving request. That is, the period immediately before the power saving request is a period for calculating the baseline, and a value equivalent to the total power in the immediately preceding period is calculated as the baseline.

  The period immediately before the power saving request is, for example, a period that ends at a time point between one hour before the power saving request and the power saving request. The length of the period immediately before the power saving request is, for example, 10 minutes to 6 hours. The length of the period immediately before the power saving request may be defined based on the length of the power saving period.

  Further, in this example, the period immediately before the power saving request is included in the period of the defrosting operation of the refrigeration equipment. That is, the period for calculating the baseline is included in the period of the defrosting operation of the refrigeration equipment. The refrigeration equipment stops the cooling operation in order to melt the frost in the defrosting operation. Therefore, in the defrosting operation, the power consumed by the refrigeration equipment is reduced, and the total power consumed by the refrigeration equipment and other equipment is also reduced.

  Further, in this example, the defrosting operation of the refrigeration equipment ends between the issuance of the power saving request and the start of the power saving period. Thereafter, the temperature that has been raised by stopping the cooling operation is restored again to a lower temperature, so that the power consumed by the refrigeration equipment temporarily becomes larger than usual. As a result, the total power consumed by the refrigeration equipment and other equipment temporarily increases.

  In this example, since the period for calculating the baseline is included in the period of the defrosting operation of the refrigeration equipment, the baseline is calculated to be low. Moreover, since the power saving period and the period in which the power consumed by the refrigeration equipment temporarily increases partially, the total power in the power saving period is basically large.

  Therefore, even if the power consumed by other devices is reduced in the power saving period, it is difficult to make the total power smaller than the baseline calculated based on the total power in the immediately preceding period. Also, in this example, a baseline that is too low is calculated, but a baseline that is too high may be calculated with large fluctuations in power. Then, there is a possibility that the power saving amount corresponding to the power reduced by the power saving is not properly evaluated and the power saving is not appropriately performed.

  In addition, the interval and timing of the defrosting operation may vary depending on the situation. Since the power consumption greatly varies due to such a defrosting operation, it is difficult to appropriately calculate the baseline of the power consumption.

  Therefore, a power saving control method according to an aspect of the present disclosure includes a step (a) of transmitting a power saving request for requesting a consumer to start power saving, and a power saving of a power load by the consumer in response to the power saving request. Calculating the baseline of the power consumption of the power load during the power saving period, and based on the difference between the actual power consumption of the power load during the power saving period of the consumer and the baseline Calculating a reward to a consumer (c), and in the step (b), the power consumption amount of the first power load including the refrigeration equipment in the power saving period, and before the power saving period The baseline is calculated based on the power consumption of a second power load different from the first power load.

  As a result, the baseline is calculated based on the power consumption of the cooling equipment during the power saving period and the power consumption of other equipment before the power saving period. Therefore, the power consumption that varies in the defrosting operation during the power saving period is reflected in the baseline. Therefore, it is possible to appropriately calculate the baseline, and it is possible to appropriately evaluate the power saving amount.

  For example, in the step (b), based on the power consumption of the first power load in the power saving period and the second power load in the past period in which the time period is the same as the power saving period, the base Lines may be calculated.

  Thereby, it is possible to appropriately calculate the baseline based on the power consumption amount of other devices in the past period whose conditions are similar to those of the power saving period.

  Further, for example, in the step (b), based on the power consumption of the first power load in the power saving period and the second power load on the same day as the power saving period and before the power saving period, A baseline may be calculated.

  Accordingly, it is possible to appropriately calculate the baseline based on the power consumption of other devices in a period relatively close to the power saving period.

  Further, for example, the second power load may include an air conditioner.

  Thereby, it is possible to appropriately calculate the baseline in an environment including the cooling equipment and the air conditioning equipment.

  For example, when the defrosting operation of the refrigeration equipment is executed in the power saving period, the method includes a step (d) of determining whether or not the defrosting operation is unscheduled, and the result of the step (d) is obtained. In consideration, the baseline may be calculated in step (b).

  Thus, whether or not an unscheduled defrosting operation is executed during the power saving period is considered in the calculation of the baseline for evaluating the power saving amount. Therefore, it is possible to reflect in the evaluation of the power saving amount whether or not an unscheduled defrosting operation is executed during the power saving period.

  In addition, for example, when it is determined in step (d) that the defrosting operation is not scheduled, in step (b), instead of the power consumption amount of the first power load in the power saving period, The baseline may be calculated based on the power consumption amount of the first power load when the defrosting operation is not executed.

  Thus, when an unscheduled defrosting operation is executed during the power saving period, a baseline is calculated based on the power consumption of the cooling equipment when the defrosting operation is not executed. Therefore, it is possible to appropriately evaluate the power saving amount obtained by the unscheduled defrosting operation during the power saving period.

  In addition, for example, when the defrosting operation of the refrigeration equipment is executed in the power saving period, the method includes a step (e) of determining whether the defrosting operation is for a power saving purpose, and the result of the step (e) is obtained. In consideration, the baseline may be calculated in step (b).

  Accordingly, whether or not a defrosting operation for power saving is executed during the power saving period is considered in the calculation of the baseline for evaluating the power saving amount. Therefore, it is possible to reflect whether or not the defrosting operation for power saving is executed in the power saving period in the evaluation of the power saving amount.

  In addition, for example, when it is determined in step (e) that the defrosting operation is for power saving, in step (b), instead of the power consumption amount of the first power load in the power saving period, The baseline may be calculated based on the power consumption amount of the first power load when the defrosting operation is not executed.

  Thus, when the defrosting operation for power saving is executed in the power saving period, the baseline is calculated based on the power consumption amount of the refrigeration equipment when the defrosting operation is not executed. Therefore, it is possible to appropriately evaluate the power saving amount obtained by the defrosting operation for power saving purpose during the power saving period.

  In addition, a power saving control system according to an aspect of the present disclosure includes a transmitter that transmits a power saving request for requesting a consumer to start power saving, and the consumer performs power saving of a power load in response to the power saving request. A first calculator that calculates a baseline of power consumption of the power load during the power saving period; and the demand based on a difference between the actual power consumption of the power load during the power saving period of the consumer and the baseline. A second calculator for calculating a reward for the house, wherein the first calculator is a power consumption amount of the first power load including the cooling equipment in the power saving period, and before the power saving period. The power saving control system may calculate the baseline based on a power consumption amount of a second power load different from the first power load.

  Thereby, the power saving control system can calculate the baseline based on the power consumption amount of the refrigeration equipment during the power saving period and the power consumption amount of other equipment before the power saving period. Therefore, the power saving control system can reflect the amount of power consumption that varies in the defrosting operation during the power saving period in the baseline. Therefore, the power saving control system can appropriately calculate the baseline, and can appropriately evaluate the power saving amount.

  The program according to an aspect of the present disclosure may be a program for causing a computer to execute the power saving control method.

  Thus, a power saving control method for appropriately evaluating the power saving amount is realized as a program.

  Note that these comprehensive or specific aspects may be realized by a system, apparatus, method, integrated circuit, computer program, or non-transitory recording medium such as a computer-readable CD-ROM. The present invention may be realized by any combination of an apparatus, a method, an integrated circuit, a computer program, or a recording medium.

(Embodiment 1)
FIG. 3 is a block diagram showing an environment including the power saving control system in the present embodiment. For example, the transmitter 111, the first calculator 112, the second calculator 113, and the storage device 114 are used and managed by the aggregator. The transmitter 111, the first calculator 112, and the second calculator 113 constitute a power saving control system 110.

  The transmitter 111 is an example of a transmitter according to the present disclosure, and is a communication device that transmits a power saving request for requesting the customer to save power during the power saving period. That is, the transmitter 111 issues a power saving request. The transmitter 111 can also be expressed as a power saving request issuing unit.

  Specifically, the transmitter 111 may include a terminal for performing wired communication or an antenna for performing wireless communication. Further, the transmitter 111 may include an arithmetic processing unit and a storage unit for controlling communication. The arithmetic processor may be an MPU or a CPU. The storage device may be a volatile memory or a non-volatile memory. A communication control program may be stored in the storage device.

  For example, the transmitter 111 transmits a power saving request to the display 201 of the store by wired or wireless communication. As a result, a power saving request is displayed on the display 201 and the store staff or the like is prompted to save power. The transmitter 111 may transmit a power saving request when receiving an instruction from the aggregator, may transmit a power saving request when receiving a power saving request from an electric power company, or when a power shortage is predicted. A power saving request may be transmitted to

  The first calculator 112 is an example of a first calculator of the present disclosure, and is a calculator that calculates a baseline. The first calculator 112 can also be expressed as a baseline calculator. The first calculator 112 may include an arithmetic processing unit and a storage unit for calculation processing. The arithmetic processor may be an MPU or a CPU. The storage device may be a volatile memory or a non-volatile memory. The storage device may store a calculation processing program.

  Here, the baseline is a reference power consumption amount for evaluating the power saving amount in the power saving period. The power saving amount can also be expressed as a power saving effect. The larger the value obtained by subtracting the actual power consumption from the baseline, the greater the power saving. The first calculator 112 calculates a baseline for the power saving period.

  Further, the first calculator 112 may transmit the baseline information indicating the baseline to the store display 201 in order to notify the store staff or the like of the baseline calculated for the power saving period.

  The second calculator 113 is an example of a second calculator of the present disclosure, and is a calculator that calculates a reward.

The second calculator 113 may include an arithmetic processing unit and a storage unit for calculation processing. The arithmetic processor may be an MPU or a CPU. The storage device may be a volatile memory or a non-volatile memory. The storage device may store a calculation processing program.

  Here, the reward can be expressed as a power saving fee. The reward corresponds to the amount of power saving. Specifically, the higher the power saving amount, the higher the reward. That is, calculating the reward appropriately corresponds to appropriately evaluating the power saving amount.

  For example, the second calculator 113 calculates the reward based on the difference between the baseline calculated by the first calculator 112 and the actual power consumption during the power saving period. Further, the second calculator 113 may transmit reward information indicating the calculated reward to the store display 201 in order to notify the calculated reward to the staff of the store.

  The storage device 114 is a storage for storing information. The storage device 114 may include a volatile memory or a nonvolatile memory for storing power information, and may also be expressed as a power information storage unit. For example, the storage device 114 stores and accumulates power information indicating the power consumption amount of the first power load 204 and the power consumption amount of the second power load 205 separately.

  Specifically, each of the power consumption of the first power load 204 and the power consumption of the second power load 205 is detected by the power detector 202 separately. Then, power information separately indicating the power consumption amount of the first power load 204 and the power consumption amount of the second power load 205 is transmitted by the controller 203 and stored in the storage device 114. The power information stored in the storage device 114 is used for the calculation of the baseline in the first calculator 112 and the calculation of the reward in the second calculator 113.

  Note that the power information indicating the power consumption amount of the first power load 204 and the power consumption amount of the second power load 205 is the power information of the first power load 204 and the second power load 205, respectively. Information capable of deriving each of the power consumption amount may be used. For example, the power information indicating each of the power consumption of the first power load 204 and the power consumption of the second power load 205 is the total power consumption of the first power load 204 and the second power load 205. And the power consumption amount of the first power load 204 may be shown.

  The display device 201 is an output device that displays information. For example, the display unit 201 displays power saving information related to power saving, and can be expressed as a power saving information display unit. The display 201 may include a cathode ray tube, a liquid crystal display, a projector, or the like for displaying information. The display unit 201 may include an arithmetic processing unit and a storage unit for controlling display. The arithmetic processor may be an MPU or a CPU. The storage device may be a volatile memory or a non-volatile memory. A display control program may be stored in the storage device.

  For example, the display unit 201 receives and displays a power saving request transmitted from the transmitter 111 before the start of the power saving period. The store staff or the like saves power during the power saving period based on the power saving request displayed on the display 201. Moreover, the display device 201 may receive and display the reward information transmitted from the second calculator 113 after the end of the power saving period. Further, the display device 201 may receive and display the baseline information transmitted from the first calculator 112.

  The power detector 202 is a detector that detects power consumption, and is, for example, a power meter installed in a store. The power detector 202 may be a smart meter including a communication device that transmits power information indicating the detected power consumption. For example, the power detector 202 detects each of the power consumption amount of the first power load 204 and the power consumption amount of the second power load 205 at a certain time interval, and indicates the detected power consumption amount. The power information is transmitted to the controller 203.

  For example, the power detector 202 detects each of the power consumption amount of the first power load 204 and the power consumption amount of the second power load 205 at regular time intervals. Then, the power detector 202 transmits power information indicating the power consumption amount of the first power load 204 and the power consumption amount of the second power load 205 to the controller 203.

  The power detector 202 may detect the total power consumption of the first power load 204 and the second power load 205 and the power consumption of the first power load 204, respectively. The power detector 202 may detect the difference between the total power consumption and the power consumption of the first power load 204 as the power consumption of the second power load 205.

  Alternatively, the power detector 202 supplies power information indicating the total power consumption of the first power load 204 and the second power load 205 and the power consumption of the first power load 204 to the controller 203. You may send it. The power information indicating each of the total power consumption of the first power load 204 and the second power load 205 and the power consumption of the first power load 204 includes the power consumption of the first power load 204 and It can be used as power information indicating each of the power consumption of the second power load 205.

  The controller 203 is a controller for controlling power consumption and the like. The controller 203 may include an arithmetic processor and a storage device. The arithmetic processor may be an MPU or a CPU. The storage device may be a volatile memory or a non-volatile memory. A control program may be stored in the storage device. The controller 203 may be configured by a single controller that performs centralized control, or may be configured by a plurality of controllers that perform distributed control in cooperation with each other.

  For example, the controller 203 receives power information indicating the power consumption detected by the power detector 202 and transmits it to the aggregator at regular time intervals. Thus, the controller 203 stores and accumulates power information indicating the power consumption detected by the power detector 202 in the aggregator storage device 114 at regular time intervals.

  Specifically, the controller 203 receives power information indicating the power consumption amount of the first power load 204 and the power consumption amount of the second power load 205 from the power detector 202 and transmits it to the aggregator. As a result, the controller 203 stores and accumulates the power information indicating the power consumption of the first power load 204 and the power consumption of the second power load 205 in the storage device 114 of the aggregator.

  Further, the controller 203 controls the power consumption of the first power load 204 and the second power load 205 by controlling the operations of the first power load 204 and the second power load 205. Good. Further, the controller 203 may acquire the operating states of the first power load 204 and the second power load 205.

  The 1st electric power load 204 is an example of the 1st electric power load of this indication, and is an electric power load containing refrigeration equipment. More specifically, the first power load 204 includes one or more cooling devices and does not include other devices different from the cooling devices.

  The refrigeration equipment is equipment for freezing or refrigeration, and may be a showcase for freezing or refrigeration, a refrigerator, a refrigerator, or the like. In particular, the refrigeration equipment performs a defrosting operation regularly or irregularly. For example, the first power load 204 includes a freezing or refrigerated showcase, a refrigerator, a refrigerator, and the like.

  The second power load 205 is an example of the second power load of the present disclosure, and is a power load different from the first power load 204. That is, the second power load 205 is a power load that does not include the refrigeration equipment, and that includes other equipment different from the refrigeration equipment. More specifically, the second power load 205 includes one or more other devices different from the refrigeration equipment, and does not include the refrigeration equipment.

  For example, the second power load 205 includes an air conditioner. The second power load 205 may further include a lighting device, a copy machine, an ATM (Automated Teller Machine), a POS (Point Of Sale) register, a warmer, a cooker, a microwave oven, and the like.

  FIG. 4 is a block diagram showing a modification of the environment shown in FIG. In this example, the transmitter 111 transmits a power saving request to the controller 203 of the store. The controller 203 receives the power saving request from the transmitter 111, and controls the operations of the first power load 204 and the second power load 205 based on the power saving request, whereby the first power load 204 and the second power load 204 are controlled. The power consumption of the power load 205 is reduced.

  The controller 203 may stop the operation of one or more devices out of the first power load 204 and the second power load 205 in order to reduce power consumption during the power saving period corresponding to the power saving request. One or more devices may be operated in the energy saving mode. For example, the controller 203 transmits a control command for reducing power consumption to one or more devices during the power saving period. Each of the one or more devices receives the control command and changes the operation according to the control command. Thereby, power consumption is reduced.

  In addition, the controller 203 may transmit a power saving request to the display device 201. The display device 201 may receive and display the power saving request transmitted from the controller 203. Thereby, a power saving request is notified to the store staff and the like. That is, the store staff or the like is notified that power saving control is performed based on the power saving request.

  In this example, the second calculator 113 calculates a reward, and transmits reward information indicating the calculated reward to the controller 203 of the store. The controller 203 receives the reward information from the second calculator 113 and transmits it to the display 201. The display 201 receives and displays the reward information transmitted from the controller 203. Thereby, the reward is notified to the staff of the store.

  Further, the first calculator 112 may calculate a baseline and transmit baseline information indicating the calculated baseline to the controller 203 of the store. Then, the controller 203 may receive the baseline information from the first calculator 112 and transmit it to the display unit 201. The display unit 201 may receive and display the baseline information transmitted from the controller 203. Thereby, the base line is notified to the staff of the store.

  In this modification, power saving is automatically performed based on a power saving request even if store staff or the like does not manually save power. Therefore, power saving is performed smoothly. Further, the controller 203 can centrally manage various information. Therefore, communication is controlled and complication of the communication environment is suppressed.

  FIG. 5 is a flowchart showing the operation of the power saving control system 110 in the environment shown in FIG. 3 or FIG.

  First, the transmitter 111 transmits a power saving request for requesting a consumer to start power saving (S101).

  Next, in response to the power saving request, power is saved by the consumer (S102). For example, power saving such as stopping the operation of one or more devices included in the power load or operating one or more devices included in the power load in the energy saving mode is performed. The power saving process itself may not be performed by the power saving control system 110. There is also a possibility that power will not be saved depending on the judgment of the customer.

  Next, the first calculator 112 calculates a baseline of the power consumption of the power load during the power saving period (S103). At this time, the first calculator 112 is based on the power consumption (α) of the first power load 204 during the power saving period and the power consumption (β) of the second power load 205 before the power saving period. Calculate the baseline. Here, the power saving period is a period during which power is saved by the consumer in response to a power saving request.

  The power consumption amount (α) of the first power load 204 during the power saving period may be the power consumption amount of the first power load 204 per unit time during the power saving period. Similarly, the power consumption (β) of the second power load 205 before the power saving period may be the power consumption of the second power load 205 per unit time before the power saving period.

  The first calculator 112 has a baseline in the sum of the power consumption (α) of the first power load 204 in the power saving period and the power consumption (β) of the second power load 205 before the power saving period. Baselines may be calculated to match.

  The power consumption amount (α) of the first power load 204 during the power saving period is basically the actual power consumption amount of the first power load 204 during the power saving period, and is the first power load during the power saving period. This is the actual value of the power consumption of 204. However, the power consumption amount (α) of the first power load 204 during the power saving period can be regarded as equivalent to the actual power consumption amount of the first power load 204 during the power saving period. As well as the planned power consumption already planned.

  The power consumption amount (β) of the second power load 205 before the power saving period may be the power consumption amount of the second power load 205 on the same day as the power saving period and before the power saving period. Specifically, the power consumption (β) of the second power load 205 before the power saving period may be the power consumption of the second power load 205 in the period immediately before the power saving request.

  The period immediately before the power saving request is, for example, a period that ends at a time point between one hour before the power saving request and the power saving request. The length of the period immediately before the power saving request is, for example, 10 minutes to 6 hours. The length of the period immediately before the power saving request may be defined based on the length of the power saving period.

  Alternatively, the power consumption amount (β) of the second power load 205 before the power saving period may be the power consumption amount of the second power load 205 in the past period with the same time zone as the power saving period. Specifically, the power consumption amount (β) of the second power load 205 before the power saving period is the second power in a plurality of periods having the same time zone as the power saving period in the past plural days with respect to the power saving period. An average value of the power consumption amount of the load 205 may be used.

  The time zone corresponds to the time zone in one day, and corresponds to the portion excluding the date in the period. In addition, in the above average value of power consumption, days with low power consumption may be excluded. For example, the average value of the power consumption amount is the power saving period and time on the four days when the power consumption amount of the second power load 205 in the same period as the power saving period is large among the past five days. The average value of the power consumption amount of the second power load 205 during the four periods with the same band may be used.

  Next, the second calculator 113 calculates a reward to the consumer based on the difference between the actual power consumption of the power load during the power saving period of the consumer and the baseline (S104). For example, a value obtained by subtracting the actual power consumption amount from the baseline corresponds to the power saving amount. The second calculator 113 calculates a higher reward as the power saving amount is larger.

  As described above, the power consumption varies greatly depending on the defrosting operation. On the other hand, the interval and timing of the defrosting operation may change depending on the situation. Therefore, it is not easy to calculate the baseline from the power consumption amounts of the first power load 204 and the second power load 205 before the power saving period.

  Therefore, the power saving control system 110 performs the baseline based on the power consumption (α) of the first power load 204 during the power saving period and the power consumption (β) of the second power load 205 before the power saving period. Is calculated. Thereby, the power saving control system 110 can reflect the amount of power consumption that varies in the defrosting operation during the power saving period in the baseline. Therefore, the power saving control system 110 can appropriately calculate the baseline, and can appropriately evaluate the power saving amount.

  The baseline as described above may be calculated for a power saving request transmitted at the latest timing of the power saving period, or for a power saving request transmitted at a timing different from the latest timing of the power saving period. May be calculated. The baseline as described above may be calculated for a power saving period that is a short period, or may be calculated for a power saving period that is not a short period.

(Embodiment 2)
In the present embodiment, the baseline is calculated by a method different from that in the first embodiment. This will be specifically described below. In the following description, the same description as in the first embodiment may be omitted.

  FIG. 6 is a block diagram showing an environment including a power saving control system in the present embodiment. In the present embodiment, the power saving control system 110a, the first calculator 112a, the storage device 114a, and the controller 203a are different from those in the first embodiment. Other components are the same as those in the first embodiment.

  The first calculator 112a is an example of the first calculator of the present disclosure, and is a calculator that calculates a baseline. The first calculator 112a is basically the same as the first calculator 112 of the first embodiment, but the baseline calculation method is different. The baseline calculation method will be described later with reference to FIG.

  The storage device 114a is a storage for storing information. The storage device 114a is basically the same as the storage device 114 of the first embodiment, but the storage device 114a stores and stores defrosting information that is information related to the defrosting operation.

  For example, the defrost information indicates a defrost state. The defrosting state corresponds to a defrosting operation or a normal operation. That is, the defrosting state corresponds to whether or not the first power load 204 is performing a defrosting operation. Further, for example, the defrosting information indicates a defrosting schedule. The defrosting schedule is a schedule of a defrosting operation to be executed in the future in the first power load 204. Specifically, the defrosting schedule may include a scheduled defrosting start time, a scheduled defrosting end time, and the like.

  The controller 203a is a controller for controlling power consumption and the like. The controller 203a is basically the same as the controller 203 of the first embodiment, but acquires defrost information and transmits it to the aggregator. Thereby, the controller 203a stores and accumulates the defrosting information in the storage device 114a of the aggregator.

  For example, the controller 203a acquires the current operation state of the refrigeration equipment included in the first power load 204. Then, the controller 203a determines the defrosting state corresponding to the defrosting operation or the normal operation based on the current operation state of the refrigeration equipment, and sequentially transmits defrosting information indicating the defrosting state to the aggregator.

  In addition, the controller 203a derives a defrosting schedule including a future defrosting start scheduled time and a defrosting scheduled end time, and transmits defrosting information indicating the defrosting schedule to the aggregator. Specifically, the controller 203a may derive the scheduled defrosting start time and the scheduled defrosting end time up to 24 hours ahead. More specifically, the controller 203a determines the future based on the average value of the time interval from the defrosting end time to the defrosting start time and the last defrosting end time in the most recent days where power saving is not performed. The scheduled defrosting start time may be derived.

  Furthermore, the controller 203a is scheduled to end the future defrosting based on the average value of the time interval from the defrosting start time to the defrosting end time and the future defrosting start time on the most recent days when power saving is not performed. The time may be derived. When the time for one defrosting operation is determined in advance, the controller 203a derives the future defrosting scheduled time based on the scheduled defrosting start time and the time for one defrosting operation. Also good.

  Similar to the modification example shown in FIG. 4, a modification example of the environment shown in FIG. 6 may be constructed. That is, a modification similar to the modification of the environment in the first embodiment can be applied to the environment in the present embodiment. Specifically, since it is the same as FIG. 4, detailed description is omitted.

  FIG. 7 is a flowchart showing the operation of the power saving control system 110a in the environment shown in FIG.

  The processing of power saving request transmission (S201), power saving (S203) and reward calculation (S204) in the present embodiment shown in FIG. 7 is performed in accordance with the transmission of power saving request in the first embodiment shown in FIG. S101), power saving (S102), and reward calculation (S104) are the same. The process of calculating the baseline (S202) in the present embodiment shown in FIG. 7 is different from the process of calculating the baseline (S103) in the first embodiment shown in FIG. In the present embodiment, the baseline calculation (S202) is performed before power saving (S203).

  In the calculation of the baseline (S202), the first calculator 112a calculates the baseline of the power consumption of the power load during the power saving period.

  Specifically, first, the first calculator 112a uses the power consumption En of the first power load 204 during normal operation, that is, the power consumption En of the first power load 204 when not performing the defrosting operation. Is derived (S211).

  The first calculator 112a may derive the power consumption En of the first power load 204 when the defrosting operation is not performed from the past results, that is, from the information stored in the storage device 114a. For example, the first calculator 112a may derive the average power consumption of the first power load 204 during the most recent normal operation as the power consumption En.

  Alternatively, the first calculator 112a may derive, as the power consumption En, the average power consumption of the first power load 204 during the normal operation in a plurality of periods having the same time period as the power saving period in the past plural days. Good. However, since the defrosting operation is shorter than the normal operation, it is assumed that the nearest normal operation is close to the power saving period. Therefore, the necessity of going back to the past multiple days is low.

  Alternatively, the first calculator 112a may derive the power consumption En of the first power load 204 when the defrosting operation is not performed by referring to a predetermined table. For example, even if the first calculator 112a uses the outside air temperature as a parameter and refers to a predetermined table, the first calculator 112a derives the power consumption En of the first power load 204 when the defrosting operation is not performed. Good.

  Next, the first calculator 112a derives the power consumption Ef of the first power load 204 during the defrosting operation, that is, the power consumption Ef of the first power load 204 during the defrosting operation ( S212).

  The first calculator 112a may derive the power consumption En of the first power load 204 when performing the defrosting operation from the past results, that is, from the information stored in the storage device 114a. For example, the first calculator 112a derives, as the power consumption Ef, the average power consumption of the first power load 204 during the defrosting operation in a plurality of periods having the same time period as the power saving period in a plurality of past days. Good.

  Alternatively, the first calculator 112a may derive the average power consumption of the first power load 204 during the most recent defrosting operation as the power consumption Ef. However, since the defrosting operation is shorter than the normal operation, the most recent defrosting operation may be away from the power saving period. Therefore, it is appropriate to go back to multiple past days.

  Alternatively, the first calculator 112a may derive the power consumption En of the first power load 204 when the defrosting operation is performed by referring to a predetermined table. For example, even if the first calculator 112a uses the outside air temperature as a parameter and refers to a predetermined table, the first calculator 112a derives the power consumption En of the first power load 204 during the defrosting operation. Good.

  Next, the first calculator 112a is a normal operation scheduled period Tn that is a period during which the refrigeration equipment is not performing the defrosting operation, and a period during which the refrigeration equipment is not performing the defrosting operation, in the power saving period. A defrosting operation scheduled period Tf is derived (S213). Specifically, the first calculator 112a includes the normal operation scheduled period Tn and the defrosting operation based on the power saving period and the defrosting schedule included in the defrosting information transmitted by the controller 203a and stored in the storage device 114a. These are derived by deriving the scheduled period Tf.

  The first calculator 112a basically derives the normal operation scheduled period Tn and the scheduled defrosting operation period Tf based on the defrosting schedule planned before the power saving request.

  Next, the first calculator 112a performs the first power saving period based on the power consumption En during the normal operation, the power consumption Ef during the defrosting operation, the normal operation scheduled period Tn, and the scheduled defrosting operation scheduled period Tf. The power consumption (α) of the power load 204 is estimated (S214). Specifically, the first calculator 112a estimates En × Tn + Ef × Tf as the power consumption (α) of the first power load 204 in the power saving period.

  The power consumption estimated from the above (α) is already planned as the power consumption during the power saving period, which can be regarded as equivalent to the actual power consumption of the first power load 204 during the power saving period. This is the planned power consumption.

  Next, the first calculator 112a is based on the power consumption (α) of the first power load 204 during the power saving period and the power consumption (β) of the second power load 205 before the power saving period. The baseline is calculated (S215). The first calculator 112a has a baseline in the sum of the power consumption (α) of the first power load 204 in the power saving period and the power consumption (β) of the second power load 205 before the power saving period. Baselines may be calculated to match.

  The power consumption (β) of the second power load 205 before the power saving period is the same as the power consumption (β) shown in the first embodiment.

  With the above operation, the power saving control system 110a can reflect the presence / absence and period of the defrosting operation scheduled for the power saving period in the baseline. Therefore, the power saving control system 110a can appropriately calculate the baseline, and can appropriately evaluate the power saving amount.

  Further, since the baseline is calculated before the start of the power saving period, the baseline may be notified to the store staff before the start of the power saving period. Thereby, the staff of the store can perform power saving based on the baseline. Alternatively, the controller 203a may automatically perform appropriate power saving based on the baseline calculated before the start of the power saving period.

  Moreover, the power saving control system 110a calculates the baseline based on the defrosting schedule. On the other hand, a defrosting operation that is not in line with the defrosting schedule may be performed in accordance with the power saving request. Specifically, the defrosting operation may be performed during the power saving period in accordance with the power saving request. Thereby, the power consumption amount in a power saving period is reduced by the defrosting operation. Since the power saving control system 110a calculates the baseline based on the defrosting schedule, the power saving amount obtained by the defrosting operation executed according to the power saving request can be appropriately evaluated.

(Embodiment 3)
In the present embodiment, the baseline is calculated by a method different from both the first embodiment and the second embodiment. This will be specifically described below. In the following description, the same description as in the first embodiment or the second embodiment may be omitted.

  FIG. 8 is a block diagram showing an environment including the power saving control system in the present embodiment. In the present embodiment, the power saving control system 110b and the first calculator 112b are different from those in the second embodiment. Other components are the same as those in the second embodiment.

  The first calculator 112b is an example of a first calculator of the present disclosure, and is a calculator that calculates a baseline. The first calculator 112b is basically the same as the first calculator 112 of the first embodiment, but the baseline calculation method is different. The baseline calculation method will be described later with reference to FIG.

  Similar to the modification example shown in FIG. 4, the environment modification example shown in FIG. 8 may be constructed. That is, a modification similar to the modification of the environment in the first embodiment can be applied to the environment in the present embodiment. Specifically, since it is the same as FIG. 4, detailed description is omitted.

  FIG. 9 is a flowchart showing the operation of the power saving control system 110b in the environment shown in FIG.

  The processing of power saving request transmission (S301), power saving (S302), and reward calculation (S304) in the present embodiment shown in FIG. 9 is performed in accordance with the power saving request transmission in the first embodiment shown in FIG. S101), power saving (S102), and reward calculation (S104) are the same. The baseline calculation process (S303) in the present embodiment shown in FIG. 9 is different from the baseline calculation process (S103) in the first embodiment shown in FIG.

  In the calculation of the baseline (S303), the first calculator 112b calculates the baseline of the power consumption of the power load during the power saving period.

  Specifically, when the defrosting operation of the refrigeration equipment is executed during the power saving period, the first calculator 112b determines whether or not the defrosting operation is unscheduled (S311). That is, the first calculator 112b determines whether or not the defrosting operation performed in the power saving period is in accordance with the defrosting schedule planned before the power saving request, based on the information stored in the storage device 114a. . If the defrosting operation is not in line with the defrosting schedule, the first calculator 112b determines that the defrosting operation was unscheduled.

  If it is determined that the defrosting operation is unscheduled (Yes in S311), the first calculator 112b uses the power consumption (γ) of the first power load 204 when the defrosting operation is not being performed. Baseline is calculated based on Specifically, the first calculator 112b uses the power consumption (γ) of the first power load 204 when the defrosting operation is not being performed and the power consumption of the second power load 205 before the power saving period. A baseline is calculated based on the quantity (β) (S312).

  That is, instead of the power consumption amount (α) of the first power load 204 during the power saving period, the power consumption amount (γ) of the first power load 204 when the defrosting operation is not performed is used. Note that the power consumption amount (β) of the second power load 205 before the power saving period is the same as the power consumption amount (β) shown in the first embodiment.

  The power consumption amount (γ) of the first power load 204 when the defrosting operation is not executed may be the power consumption amount of the first power load 204 per unit time when the defrosting operation is not executed. In addition, the first calculator 112b uses the power consumption (γ) of the first power load 204 when the defrosting operation is not performed and the power consumption (β of the second power load 205 before the power saving period). ) May be calculated so that the baseline matches the total.

  The first calculator 112b derives the power consumption (γ) of the first power load 204 when the defrosting operation is not performed from the past results, that is, from the information stored in the storage device 114a. Also good.

  Specifically, the average power consumption of the first power load 204 during the normal operation in a plurality of periods having the same time period as the power saving period in the past plural days is the first when the defrosting operation is not performed. May be derived as the amount of power consumption (γ) of the power load 204. Appropriate information can be obtained because the outside air temperature during the same period as the power saving period is assumed to be close to the outside temperature during the power saving period.

  However, the average power consumption of the first power load 204 during the normal operation in the period immediately before the power saving request is derived as the power consumption (γ) of the first power load 204 when the defrosting operation is not performed. May be. Thereby, information at the time of normal operation close in time to the power saving period is used.

  Alternatively, the first calculator 112b may derive the power consumption (γ) of the first power load 204 when the defrosting operation is not executed by referring to a predetermined table. For example, the first calculator 112b refers to a predetermined table using the outside air temperature as a parameter, and thereby calculates the power consumption amount (γ) of the first power load 204 when the defrosting operation is not performed. It may be derived.

  If it is determined that the defrosting operation is not unscheduled (No in S311), the first calculator 112b calculates the baseline (S313), as in the first embodiment.

  That is, when the defrosting operation is in line with the defrosting schedule, the first calculator 112b determines the power consumption amount (α) of the first power load 204 in the power saving period and the second power load 205 before the power saving period. A baseline is calculated based on the power consumption (β). The first calculator 112b has a baseline in the sum of the power consumption (α) of the first power load 204 in the power saving period and the power consumption (β) of the second power load 205 before the power saving period. Baselines may be calculated to match.

  With the above operation, whether or not an unscheduled defrosting operation is performed during the power saving period is considered in the calculation of the baseline for evaluating the power saving amount. Therefore, the power saving control system 110b can reflect in the evaluation of the power saving amount whether or not an unscheduled defrosting operation is executed during the power saving period.

  Further, when an unscheduled defrosting operation is performed during the power saving period, a baseline is calculated based on the power consumption when the defrosting operation is not performed. Therefore, the power saving control system 110b can appropriately evaluate the power saving amount obtained by the unscheduled defrosting operation in the power saving period.

  In particular, the unscheduled defrosting operation performed during the power saving period is assumed to be a defrosting operation performed according to the power saving request. That is, the power saving control system 110b can appropriately evaluate the power saving amount obtained by the defrosting operation executed according to the power saving request.

(Embodiment 4)
In the present embodiment, the baseline is calculated by a method different from those in the first to third embodiments. This will be specifically described below. In the following description, the same description as in any of the first to third embodiments may be omitted.

  FIG. 10 is a block diagram showing an environment including the power saving control system in the present embodiment. In the present embodiment, the power saving control system 110c, the first calculator 112c, the storage device 114c, and the controller 203c are different from those in the third embodiment. Other components are the same as those in the third embodiment.

  The first calculator 112c is an example of the first calculator of the present disclosure, and is a calculator that calculates a baseline. The first calculator 112c is basically the same as the first calculator 112b of the third embodiment, but the baseline calculation method is different. The baseline calculation method will be described later with reference to FIG.

  The storage device 114c is a storage for storing information. The storage device 114c is basically the same as the storage device 114a of the third embodiment, and the storage device 114c stores and accumulates defrosting information regarding the defrosting operation.

  For example, the defrost information indicates a defrost state. The defrosting state corresponds to a defrosting operation or a normal operation. That is, the defrosting state corresponds to whether or not the first power load 204 is performing a defrosting operation. Further, for example, the defrost information indicates the purpose of defrosting. The defrosting purpose corresponds to whether it is a power saving purpose. In the present embodiment, the defrosting information may not indicate the defrosting schedule shown in the third embodiment.

  The controller 203c is a controller for controlling power consumption and the like. The controller 203c is basically the same as the controller 203a of the third embodiment, acquires defrost information and transmits it to the aggregator. Thereby, the controller 203c stores and accumulates the defrosting information in the storage device 114c of the aggregator.

  For example, the controller 203c acquires the current operation state of the refrigeration equipment included in the first power load 204. And the controller 203c determines the defrosting state of defrosting operation | movement or normal operation | movement based on the present operation state of refrigeration equipment, and transmits sequentially the defrosting information which shows a defrosting state to an aggregator. Further, the controller 203c determines whether or not the executed defrosting operation is for power saving, that is, determines the defrosting purpose, and transmits defrosting information indicating the determined defrosting purpose to the aggregator.

  The controller 203c determines that the defrosting operation is for the purpose of power saving when the chilling device is caused to execute the defrosting operation during the power saving period in response to the power saving request. On the other hand, the controller 203c determines that the defrosting operation executed as usual is not for power saving. Alternatively, the store staff may input the defrosting purpose to the controller 203c. For example, a store staff may cause the refrigeration equipment to execute a defrosting operation based on a power saving request, and input the purpose of power saving to the controller 203c as a power saving purpose. Then, the controller 203c may determine the purpose of defrosting based on the input of the purpose of defrosting.

  Similar to the modification example shown in FIG. 4, the environment modification example shown in FIG. 10 may be constructed. That is, a modification similar to the modification of the environment in the first embodiment can be applied to the environment in the present embodiment. Specifically, since it is the same as FIG. 4, detailed description is omitted.

  FIG. 11 is a flowchart showing the operation of the power saving control system 110c in the environment shown in FIG.

  The processing of power saving request transmission (S401), power saving (S402), and reward calculation (S404) in the present embodiment shown in FIG. 11 is performed in accordance with the transmission of power saving request in the third embodiment shown in FIG. S301), power saving (S302), and reward calculation (S304). The process of calculating the baseline (S403) in the present embodiment shown in FIG. 11 is different from the process of calculating the baseline (S303) in the third embodiment shown in FIG.

  In the calculation of the baseline (S403), the first calculator 112c calculates the baseline of the power consumption of the power load during the power saving period.

  Specifically, when the defrosting operation of the refrigeration equipment is executed during the power saving period, the first calculator 112c determines whether or not the defrosting operation was for the purpose of power saving (S411). For example, the first calculator 112c determines whether or not the defrosting operation is for power saving based on the information stored in the storage device 114c.

  When it is determined that the defrosting operation is for power saving (Yes in S411), the first calculator 112c uses the power consumption (γ) of the first power load 204 when the defrosting operation is not executed. Baseline is calculated based on Specifically, the first calculator 112c uses the power consumption (γ) of the first power load 204 when the defrosting operation is not being performed and the power consumption of the second power load 205 before the power saving period. Based on the quantity (β), a baseline is calculated (S412).

  That is, instead of the power consumption amount (α) of the first power load 204 during the power saving period, the power consumption amount (γ) of the first power load 204 when the defrosting operation is not performed is used. Note that the power consumption amount (β) of the second power load 205 before the power saving period is the same as the power consumption amount (β) shown in the first embodiment.

  Further, the power consumption amount (γ) of the first power load 204 when the defrosting operation is not executed is the same as the power consumption amount (γ) shown in the third embodiment. The first calculator 112c includes a power consumption amount (γ) of the first power load 204 when the defrosting operation is not performed, and a power consumption amount (β) of the second power load 205 before the power saving period. The baseline may be calculated so that the baseline matches the sum of.

  If it is determined that the defrosting operation is not for power saving (No in S411), the first calculator 112c calculates the baseline (S413), as in the first embodiment.

  That is, if the defrosting operation for power saving is not executed, the first calculator 112c uses the power consumption (α) of the first power load 204 in the power saving period and the second power load 205 before the power saving period. The baseline is calculated based on the power consumption (β). The first calculator 112c has a baseline in the sum of the power consumption (α) of the first power load 204 in the power saving period and the power consumption (β) of the second power load 205 before the power saving period. Baselines may be calculated to match.

  With the above operation, whether or not a defrosting operation for power saving is performed during the power saving period is considered in the calculation of the baseline for evaluating the power saving amount. Therefore, the power saving control system 110c can reflect in the evaluation of the power saving amount whether or not the defrosting operation for power saving is executed during the power saving period.

  In addition, when the defrosting operation for power saving is executed in the power saving period, the baseline is calculated based on the power consumption when the defrosting operation is not executed. Therefore, the power saving control system 110c can appropriately evaluate the power saving amount obtained by the defrosting operation for the power saving purpose in the power saving period.

  In particular, the defrosting operation for power saving performed in the power saving period is assumed to be a defrosting operation performed in accordance with the power saving request. That is, the power saving control system 110c can appropriately evaluate the power saving amount obtained by the defrosting operation executed according to the power saving request.

  As described above, the power saving control system and the like according to the present disclosure can appropriately evaluate the power saving amount.

  In the above embodiment, each component may be configured by dedicated hardware or may be realized by executing a software program suitable for each component. Each component may be realized by a program executor such as a CPU or a processor reading and executing a software program recorded on a recording medium such as a hard disk or a semiconductor memory. Here, the software that implements the power saving control system of the above embodiment is the following program.

  That is, the program includes a step (a) of transmitting to the computer a power saving request for requesting a consumer to start power saving, and a power saving period in which the consumer saves a power load in response to the power saving request. A step of calculating a baseline of power consumption of the power load (b), and a reward to the consumer based on a difference between the actual power consumption of the power load during the power saving period of the consumer and the baseline And calculating the power consumption amount of the first power load including the cooling equipment in the power saving period, and in the step (b), the first power before the power saving period. A power saving control method for calculating the baseline based on a power consumption amount of a second power load different from the power load is executed.

  In the above embodiment, each component may be a circuit. A plurality of components may constitute one circuit as a whole, or may constitute separate circuits. Each circuit may be a general-purpose circuit or a dedicated circuit.

  As mentioned above, although the power-saving control system etc. which concern on one or several aspects were demonstrated based on embodiment, this indication is not limited to this embodiment. Unless it deviates from the gist of the present disclosure, various modifications conceived by those skilled in the art have been made in this embodiment, and forms constructed by combining components in different embodiments are also within the scope of one or more aspects. May be included.

  For example, in the above-described embodiment, a process executed by a specific component may be executed by another component instead of the specific component. Further, the order of the plurality of processes may be changed, and the plurality of processes may be executed in parallel.
