- the average power consumption of the equipment 200 in the time before and after the reference time and the average power of the equipment 200 in the time period of several days up to the day including the reference time You may take into consideration the transition of power consumption.
- the limit value setting unit 330 sets a limit value for each customer constituting the group with respect to the average power consumption for each time period by the equipment 200 of each consumer based on the prediction result by the first prediction unit 320.
- the limit value setting unit 330 is an example of setting means. If the average power consumption of a group exceeds the contracted power of the group, this average power consumption becomes a new contracted power and raises the basic charge of electricity charges. Therefore, it is required to set a target power based on the contract power for the group and control the average power consumption for each time period so as not to exceed the target power in the entire equipment 200 of the group. Then, the limit value for each time limit is set so that the integrated value of the limit value of each consumer is equal to or less than the threshold value based on the target power.
- the target power is set to a value equal to or less than the contract power, for example, a value lower than the contract power by a certain value.
- the threshold value is set to a value equal to or less than the target power, for example, a value lower than the target power by a certain value.
- the limit value of each of the consumers constituting the group is set based on, for example, the prediction of the average power consumption for each consumer by the first prediction unit 320. From the prediction of the first prediction unit 320, the ratio of the average power consumption predicted by each consumer of the group is specified for each time period. Therefore, for example, when the integrated value of the limit value of each consumer is set to be equal to the threshold value based on the above target power, the average power consumption corresponding to this threshold value is predicted by the first prediction unit 320. Allocate the power so that it is the ratio of the average power consumption by the consumers, and use it as the limit value for each consumer. In other words, the limit value means the power consumption available to each consumer in that time period.
- the limit value is set based on the actual value of the average power consumption for each time period in the past specific period of each customer, instead of the ratio of the average power consumption for each time period for each consumer. good.
- the ratio of the actual value of the average power consumption of each consumer in the reference time period shown in the same explanation is specified with respect to the specific time period shown in the explanation of the prediction by the first prediction unit 320.
- a limit value for each consumer in a specific time period may be set based on the ratio of the actual value.
- the specific period may be set according to the amount of information obtained as the actual value of the reference time period, for example, set for the past one year or several years, or between a specific date and a specific date. You may.
- the limit value may be set based on the maximum value of the average power consumption for each time period in a specific period of each consumer. For example, assuming that the specific period is the past one year, the maximum value of the average power consumption for each time period in the past one year can be obtained for each consumer. Then, the maximum value of each consumer may be compared, and the limit value of each consumer may be set at a ratio according to the ratio. In this case, unlike the case where the actual value of the reference time is used, the time when the average power consumption becomes the maximum value may be different for each consumer.
- the limit value setting unit 330 is set as follows. May be set.
- the limit value set for each consumer in a certain time period may be set to a higher value than the limit value of the immediately preceding time period or a lower value depending on the customer. Therefore, the total difference between the limit value of the immediately preceding time period and the limit value set for all consumers for which a limit value higher than the limit value of the immediately preceding time limit is set is lower than the limit value of the immediately preceding time limit. Compare the sum of the differences between the limit value of the immediately preceding time period and the set limit value for all consumers for which the limit value is set. Then, the limit value of each consumer is set so that the former does not become larger than the latter.
- a lower limit value may be set as the limit value.
- the lower limit is a value greater than 0.
- a limit value corresponding to the lower limit value is set even when the average power consumption in a certain time period is predicted to be 0 for a certain consumer. This is because when the average power consumption is predicted to be 0 for a certain consumer and the limit value is set to 0, the limit value is immediately exceeded when the consumer uses the equipment 200 in that time limit. Therefore, this is to avoid such inconvenience.
- the case where the average power consumption is predicted to be 0 may be, for example, the case where the average power consumption of the consumer in the reference time period used for the prediction by the first prediction unit 320 is 0.
- the lower limit setting method may be appropriately determined according to the operation and specifications of the control system, the agreement between the group and individual consumers, and the like. For example, a fixed value may be set in advance, or a value that fluctuates based on a predicted value of the average power consumption for each time period in the entire group may be used. When a fixed value is set as the lower limit value, the same value may be set for each consumer, or a separate value may be set for each consumer according to appropriate conditions and demands of the consumer.
- the predicted value of the average power consumption for each time period in the entire group is obtained by integrating the predicted value of the average power consumption for each time period in each consumer constituting the group by the first prediction unit 320.
- the lower limit threshold value is set for the limit value, and when the limit value given to a certain consumer is lower than the lower limit value, the lower limit value is applied as the limit value. Is also good.
- a value different from the lower limit value may be set. For example, if a value lower than the lower limit value is set as the lower limit threshold value, when the limit value assigned to a certain customer falls below the lower limit threshold value in a certain time period, the lower limit value larger than the lower limit threshold value is the demand in that time period. Set as a house limit.
- a limit value is set for the average power consumption of each time period by the equipment 200 for each customer.
- a configuration in which a limit value is set only for the average power consumption for a period satisfying a specific condition may be used. For example, by integrating the predicted values of the average power consumption of a certain time period in each consumer constituting the group by the first prediction unit 320, the predicted value of the average power consumption of the entire group in that time period can be obtained.
- a limit value may be set only for the average power consumption in such a time period, provided that the predicted value of the average power consumption of this group exceeds the above threshold value.
- the threshold is set based on the target power, and the target power is set based on the contract power. Therefore, when many of the consumers who make up a group do not use a large amount of power in a certain time period (for example, the time zone from midnight to dawn), the predicted value of the average power consumption of the group for that time period has a large threshold value. It is possible that it will fall below. In such a case, set the limit value of each consumer in the group to a value higher than the predicted value of the average power consumption of each consumer within the range where the integrated value of the limit value of each consumer does not exceed the threshold value. May be.

Therefore, even if some control devices 100 take over the control information of the immediately preceding time period due to the interruption of communication as described above, the integrated value of the limit value of each consumer in that time period is equal to or less than the above threshold value. There must be.
- the server 300 sets the control information that the limit value of the target time period is lower than the limit value of the immediately preceding time period, and the limit value of the target time period is higher than the limit value of the immediately preceding time period. It is transmitted before the control information. By doing so, no matter where the transmission of the control information in one target time period is interrupted, the limit value included in the control information that has been transmitted by the time the interruption is interrupted and the transmission is not performed.

- the server 300 is the consumer (5), the consumer (2), the consumer (3), and the consumer. Control information is transmitted in the order of (1) and consumer (4).
- FIG. 10 is a diagram showing an example in which communication is interrupted when control information is transmitted.
- the communication is interrupted when the control information of the consumer (3) is transmitted.
- the control device 100 corresponding to each consumer is the second period.
- the equipment 200 is controlled according to the acquired control information of the second period.

- the consumer (4) is 200 kW.
- the control device 100 corresponding to each consumer inherits the limit value of the immediately preceding first period. Controls the equipment 200. Therefore, as shown in FIG. 10, the limit value in the control of the second time period is 50 kW for the consumer (2) and 250 kW for the consumer (5).
- the control device 100 cannot acquire the control information of the corresponding time period (second time period)
- the control device 100 inherits the limit value of the previous time period (first time period), but controls the equipment 200. It is not necessary to do itself according to the control information of the previous time period.
- the equipment 200 may be controlled according to a control method prepared in advance for use when control information cannot be acquired, provided that the inherited limit value is not exceeded.
- control information in which the limit value of the target time period is lower than the limit value of the immediately preceding time period is set to the limit value of the immediately preceding time period. Therefore, it was decided to send the control information before the control information in which the limit value of the target time period becomes higher.
- control information with a lower limit value for the target time period is transmitted in order from the control information with the largest decrease, and control information with a higher limit value for the target time period is transmitted from the control information with the smaller increase range. I decided to send them in order.
- the transmission order of the control information is sequentially transmitted for each consumer, and when the transmission of the control information of one consumer is completed, the total of the limit values in all the control information that has been transmitted up to that point is the sum of the limit values.
- the order may not be greater than the sum of the corresponding consumer limits in the last time period. Therefore, some examples can be considered as the possible transmission order.
- the transmission order of the control information whose target time limit value is lower or higher is not necessarily the lower limit value. It does not have to depend on the width or the rise width.
- the control information of the consumer (1) and the consumer (4) is first, and then the consumer (2) and the consumer (consumer (2)).
- the control information of 3) and the consumer (5) may be transmitted later. So, for example, Demander (1) ⁇ Demander (4) ⁇ Demander (5) ⁇ Demander (3) ⁇ Demander (2) You may send in the order like.
- the transmission order of control information is such that when the transmission of control information of one consumer is completed, the total of the limit values that have been transmitted up to that point is greater than the total of the limit values of the corresponding consumers in the immediately preceding time period. It suffices if the order does not increase. Therefore, the control information to be transmitted first needs to be the control information in which the limit value of the target time period is lower than the limit value of the immediately preceding time period, but the control information to be transmitted after the second time is not necessarily the target. It is not necessary that the control information for which the time limit value is lower comes first. For example, in the example of the control information of the second time period of FIGS. 9 and 10.
- Demander (1) ⁇ Demander (3) ⁇ Demander (4) ⁇ Demander (2) ⁇ Demander (5) You may send in the order like.
- the transmission timing of such control information is not particularly limited.
- the control information in which the limit value of the target time period is lower than the limit value of the immediately preceding time period may be sent before the control information in which the limit value of the target time period is higher.
- the limit value can be set before the start of the time limit in which the control based on the control information is performed, and the limit value can be adjusted after the start of the time limit, but before the start of the time limit.
