About the electric power reduction by a consumer side, the case where a consumer side performs manually and the case where it performs automatically from the electric power supplier side are described.

JP 2002-176729 A

In Patent Document 1, it is not settled how much power is actually reduced in each of the power consuming devices to be subjected to power reduction. That is, in Patent Document 1, only the increase or decrease in the received power at the power receiving point to which the plurality of power consuming devices on the consumer side are connected, that is, the total power consumption by the plurality of power consuming devices on the consumer side is only seen. is there. Therefore, even if the power reduction according to the power reduction command is properly performed in the specific power consumption device targeted for power reduction, if the power consumption of other power consumption devices increases at the same time, the consumer side has There is a problem in that the total power consumption by the plurality of power consuming devices does not show the amount of power reduction that should have been appropriately performed by the consumer.
Furthermore, when the consumer has a private power generator, if the power generated by the private power generator changes, the received power at the consumer's power receiving point changes accordingly. As a result, even if a specific power consuming device targeted for power reduction has been properly reduced in accordance with the power reduction command, the power received at the receiving point should be reduced appropriately by the customer. Minutes will not appear.

The characteristic configuration of the power adjustment amount deriving device according to the present invention for achieving the above-described object is that the power consumption increase / decrease adjustment is transmitted from at least one power consuming device provided by a consumer via a communication line from a remote location. Power consumption increase / decrease adjustment according to remote command information including at least information on the increase / decrease adjustment time zone to be performed, and the at least one power consuming device has other power consumption of the consumer Used in a power receiving system connected to a power system together with at least one of a device and a private power generator,
An information communication unit that obtains at least information on the increase / decrease adjustment time zone, and information on an actual power consumption amount by the at least one power consuming device in the increase / decrease adjustment time zone;
In the at least one power consuming device, the power adjustment amount corresponding to the power consumption amount increased or decreased according to the remote command information during the increase / decrease adjustment time zone is set as the at least one power consumption in the increase / decrease adjustment time zone. It is in the point provided with the derivation | leading-out part derived | led-out based on the information regarding the actual power consumption by an apparatus.

  According to the above characteristic configuration, it is not based on the received power amount at the power receiving point of the customer as in the past, but based on the actual power consumption amount by the power consumption device that is the target of the power consumption increase / decrease adjustment. The power adjustment amount corresponding to the power consumption amount increased or decreased in accordance with the remote command information is derived in the power consumption device during the increase / decrease adjustment time period. In other words, a power consuming device is connected to the power receiving point of the consumer in addition to the power consuming device that is the target of the increase / decrease adjustment of the power consumption, and the power consumption of the power consuming device is temporally adjusted in the increase / decrease adjustment time zone. Even if it has changed, it is possible to accurately derive only the amount of power adjustment by the power consuming device that is the target of the power consumption increase / decrease adjustment.

In some cases, the actual power consumption by the power consuming device that is the target of the power consumption increase / decrease adjustment does not vary greatly over time. That is, the power consumption value in the power consuming device when the increase / decrease adjustment is not performed according to the remote command information during the increase / decrease adjustment time zone is the same as the power consumption value in the time zone before and after the increase / decrease adjustment time zone. May be considered.
Therefore, as in this feature configuration, the derivation unit calculates the difference between the actual power consumption in the increase / decrease adjustment time zone and the actual power consumption in the previous time zone or the subsequent time zone, The calculation result can be accurately derived as a power adjustment amount by the consumer.

Still another characteristic configuration of the power adjustment amount deriving device according to the present invention is an increase / decrease in which at least one power consuming device provided by a consumer is to be adjusted to increase / decrease power consumption transmitted from a remote place via a communication line. The power consumption is increased or decreased according to remote command information including at least information related to the adjustment time zone, and the at least one power consuming device includes another power consuming device and private power generation provided by the consumer. Used in a power receiving system connected to the power system together with at least one of the devices,

And a derivation unit that derives power adjustment amounts corresponding to the adjusted power consumption amounts.

If the remote command information has not been received, the power consumption device that is the target of the power consumption increase / decrease adjustment should be operating in the increase / decrease adjustment time zone, and if the remote command information has been received, the increase / decrease adjustment time zone In this case, the power supply to the power consuming device that is the target of the power consumption increase / decrease adjustment may be reliably cut off. For example, there is a case in which there is a lighting device that is always lit unless receiving remote command information, and when the remote command information is received, power supply to the lighting device is automatically cut off.
Therefore, as in this feature configuration, the derivation unit calculates the product of the length of the increase / decrease adjustment time period and the predetermined power consumption value of the power consumption device that is the target of the power consumption increase / decrease adjustment, and the calculation result Can be accurately derived as the amount of power adjustment by the consumer.

<First Embodiment>
The configuration of the power adjustment amount derivation device 20 according to the first embodiment will be described below with reference to the drawings.
FIG. 1 is a diagram for explaining the configuration of a power adjustment amount deriving device 20 and a power receiving system S1 (S) in which it is used. As shown in FIG. 1, the customer 10 includes a private power generation device 12 and a power consumption device 11 connected to the power system 1. The private power generation device 12 includes a generator 13 and a command unit 14. Although FIG. 1 shows an example in which the customer 10 has one private power generation device 12 and four power consumption devices 11, the private power generation device 12 and the power consumption device 11 that the customer 10 has. The number of can be changed as appropriate. In the example shown in FIG. 1, the generator 13 is connected to the lead-in line 2 via the circuit breaker CB1, and the power consuming device 11A is connected to the lead-in line 2 via the circuit breaker CB2. The consuming device 11C is connected to the lead-in line 2 via the circuit breaker CB3, and the power consuming device 11D is connected to the lead-in line 2 via the circuit breaker CB4.

  The command unit 14 included in the private power generator 12 sets the generated power command value so that the generator 13 operates according to the on-site power command value set on the consumer 10 side with respect to the power value to be generated by the generator 13. This is given to the generator 13. The on-site power command value is a value manually input by the customer 10 or a value stored in advance by the command unit 14 as a default value. However, it may be determined that this customer 10 cannot supply privately generated power to the power system 1 (so-called reverse power flow). In such a case, the command unit 14 determines the generated power command value for the private power generator 12 so that the received power value at the power receiving point A is at least 0 (zero) or more. That is, the generator 13 is commanded after changing the generated power command value to a value smaller than the field-side power command value.

  Of the four power consuming devices 11 that the customer 10 has, the power consuming devices 11B, 11C, and 11D relate to an increase / decrease adjustment time zone that is transmitted from a remote location via the communication line 3 and that should be adjusted to increase or decrease power consumption. The power consumption is increased or decreased according to remote command information including at least information. In FIG. 1, these three power consuming devices 11B, 11C, and 11D are represented as increase / decrease adjustment target devices.

  In the present embodiment, the remote command information includes at least information related to an increase / decrease adjustment time zone in which the power consumption increase / decrease adjustment is to be performed, and prompts the consumer 10 that received the output presentation of this information to increase / decrease the power consumption. If you can. For example, the remote command information includes information indicating an increase / decrease adjustment time zone (such as “between time t1 and time t2” and “reducing power consumption between time t1 and time t2”). The remote command information is determined by the control center 4 and transmitted to the customer 10 via the communication line 3.

  The customer 10 includes an information receiving unit 16 that can receive this remote command information transmitted from the control center 4 via the communication line 3, a control unit 15, and an output presentation unit 17. The output presentation part 17 is comprised with the apparatus which can output and present information to the consumer 10 with character information, audio | voice information, etc. For example, there are a printing device that prints and outputs character information on paper, a variety of display devices that display character information on a liquid crystal screen, and a device that conveys the contents of remote command information to the customer 10 by voice. When the information receiving unit 16 receives the remote command information, the control unit 15 causes the customer 10 to present the content of the remote command information using the output presentation unit 17 based on the content.

  That is, in this embodiment, the consumer 10 does not automatically adjust the power consumption increase / decrease, but the consumer 10 receiving the remote command information voluntarily adjusts the power consumption increase / decrease. Urging. Therefore, it is difficult to know how much power consumption increase / decrease adjustment has been made by the customer 10 who has received the remote command information, but it is required to accurately derive it. Thus, an apparatus for deriving how much power consumption has been adjusted by the consumer 10 is the power adjustment amount deriving apparatus 20 of the present embodiment.

  The power adjustment amount deriving device 20 includes information on the increase / decrease adjustment time zone, and at least one power consumption device 11 in the increase / decrease adjustment time zone (in this embodiment, the power consumption devices 11B, 11C, and 11D that are the increase / decrease adjustment target devices). ) Corresponds to the power consumption that is increased or decreased according to the remote command information during the increase / decrease adjustment time period in the information communication unit 21 that acquires at least information on the actual power consumption by the power consumption apparatuses 11B, 11C, and 11D. A deriving unit 22 for deriving the power adjustment amount to be calculated based on information on the actual power consumption amount by the power consumption devices 11B, 11C, and 11D in the increase / decrease adjustment time period. Information related to the increase / decrease adjustment time zone can be acquired by the information communication unit 21 receiving a transmission from the control unit 15 of the customer 10, and the information can be stored in the storage unit 23. The power consumption amount in the power consuming devices 11B, 11C, and 11D can be acquired by the information communication unit 21 receiving the measurement value of the power amount at the connection point B and the connection point C, and the value is stored in the storage unit 23. Can be kept.

  Furthermore, the power adjustment amount derivation device 20 includes a storage unit 23 that stores information related to past power consumptions by the power consumption devices 11B, 11C, and 11D, which are increase / decrease adjustment target devices in the increase / decrease adjustment time zone. Then, the information communication unit 21 of the power adjustment amount deriving device 20 acquires and derives information on the increase / decrease adjustment time zone and information on the actual power consumption by the power consumption devices 11B, 11C, and 11D in the increase / decrease adjustment time zone. The unit 22 adjusts the difference between the actual power consumption by the power consumption devices 11B, 11C, and 11D during the increase / decrease adjustment time period and the past power consumption by the power consumption devices 11B, 11C, and 11D during the increase / decrease adjustment time period. Derived as a quantity.

An example of power adjustment in the consumer 10 will be described below with reference to FIG.
FIG. 2 shows a temporal change (solid line) of the power consumption value (the sum of the power consumption value at the connection point B and the power consumption value at the connection point C) of the power consumption device 11 that is the increase / decrease adjustment target device, and the past. It is a graph which shows the time change (broken line) of the power consumption value of the same power consuming apparatus 11. In FIG. 2, before the start time t1 of the increase / decrease adjustment time zone, the customer 10 does not perform power adjustment. After that, at time t1, until the end time t2 of the increase / decrease adjustment time zone, the consumer 10 adjusts the increase / decrease by suppressing the power consumption of any of the power consumption devices 11 or turning off the power consumption device 11. The power consumption of the power consuming device 11 that is the target device is reduced.
Thus, the deriving unit 22 uses the actual power consumption in the increase / decrease adjustment time zone (the product of the actual power consumption value and the length (time) of the increase / decrease adjustment time zone) and the past consumption in the increase / decrease adjustment time zone. The difference between the power amount (the product of the past power consumption value and the length (time) of the increase / decrease adjustment time zone) is determined as the power adjustment amount performed by the customer 10.

  Depending on the consumer, the power consumption apparatuses 11B, 11C, and 11D that are the targets of the power consumption increase / decrease adjustment have regularity, so that the actual power consumption of the power consumption apparatus 11 in the increase / decrease adjustment time period is the same. It may be the same as the past power consumption in the increase / decrease adjustment time zone. Further, it can be known in advance that there is regularity in the operation mode of the power consumption apparatus 11 that is the target of the power consumption increase / decrease adjustment. Therefore, as in the present embodiment, the derivation unit 22 performs the actual power consumption by the power consumption devices 11B, 11C, and 11D that are the targets of the power consumption increase / decrease adjustment in the increase / decrease adjustment time zone, and the consumption in the increase / decrease adjustment time zone. By calculating the difference from the past power consumption by the power consuming apparatuses 11B, 11C, and 11D that are the targets of the power increase / decrease adjustment, the calculation result can be accurately derived as the power adjustment amount by the customer 10.

  Further, in the present embodiment, the deriving unit 22 transmits the derived value of the power adjustment amount in the increase / decrease adjustment time zone and the information communication unit 21 acquired from the control center 4 to the customer 10 via the communication line. Alternatively, information related to the increase / decrease adjustment time zone in which the power consumption increase / decrease adjustment should be performed may be stored in the storage unit 23 in association with each other. In this way, the derivation unit 22 stores the power adjustment amount in the derived increase / decrease adjustment time period and the information related to the increase / decrease adjustment time period transmitted from the control center 4 to the customer 10 in association with each other, thereby increasing / decreasing the increase / decrease adjustment. It becomes possible to confirm later how the power adjustment by the customer was performed in the time zone.

Second Embodiment
The power adjustment amount deriving device 20 of the second embodiment differs from the first embodiment in the method of deriving the power adjustment amount by the deriving unit 22. The power adjustment amount derivation device 20 of the second embodiment will be described below, but the description of the same configuration as that of the first embodiment will be omitted.

FIG. 3 is a graph showing temporal changes in the power consumption (the sum of the power consumption value at the connection point B and the power consumption value at the connection point C) of the power consumption devices 11B, 11C, and 11D that are increase / decrease adjustment target devices. It is. In the present embodiment, the past power consumption amount as in the first embodiment is not referred to in order to derive the power adjustment amount by the customer 10. Instead, in this embodiment, the power in the prior time zone (the time zone between the start time t0 and the end time t1) prior to the start time of the increase / decrease adjustment time zone for the same length as the increase / decrease adjustment time zone. Refer to the actual power consumption by the consuming devices 11B, 11C, and 11D.
In the power adjustment amount derivation device 20 according to the present embodiment, the information communication unit 21 has information on the increase / decrease adjustment time zone and information on the actual power consumption by the power consuming devices 11B, 11C, and 11D in the increase / decrease adjustment time zone. And, information on the actual power consumption by the power consuming devices 11B, 11C, and 11D in the previous time period before the start time of the increase / decrease adjustment time period is acquired and derived for the period of the same length as the increase / decrease adjustment time period The unit 22 derives a difference between the actual power consumption amount in the increase / decrease adjustment time zone and the actual power consumption amount in the prior time zone as the power adjustment amount.

  In some cases, the actual power consumption by the power consuming devices 11B, 11C, and 11D that are the targets of the power consumption increase / decrease adjustment does not vary significantly over time. That is, the power consumption values in the power consuming apparatuses 11B, 11C, and 11D when the increase / decrease adjustment is not performed according to the remote command information during the increase / decrease adjustment time zone are the prior time zones before the increase / decrease adjustment time zone. May be considered the same as the power consumption value. Therefore, as in the present embodiment, the derivation unit 22 calculates the difference between the actual power consumption in the increase / decrease adjustment time zone and the actual power consumption in the prior time zone, so that the calculation result is the demand. The amount of power adjustment by the house 10 can be accurately derived. Alternatively, although not shown in FIG. 3, the derivation unit 22 is behind the end time t2 of the increase / decrease adjustment time zone by the actual power consumption in the increase / decrease adjustment time zone and the period of the same length as the increase / decrease adjustment time zone. The difference from the posterior time zone may be calculated, and the calculation result may be determined as the power adjustment amount by the customer 10.

<Third Embodiment>
In the third embodiment, the consumer 10 does not simply receive from the control center 4 remote command information that prompts the power consumption increase / decrease adjustment, but the power consumption of the power consumption device 11 is automatically adjusted to increase / decrease. It differs from the said embodiment demonstrated with reference to FIG. 1 by the point comprised so that control may be received. The third embodiment will be described below, but the description of the same configuration as the above embodiment will be omitted.

FIG. 4 is a diagram illustrating the configuration of the power adjustment amount deriving device 20 and the power receiving system S2 (S) in which it is used.
In the power receiving system S <b> 2 of the present embodiment, the power consumption devices 11 </ b> B, 11 </ b> C, and 11 </ b> D as the increase / decrease adjustment target devices of the customer 10 are configured such that the power consumption value is automatically controlled by the control unit 15. For example, if the control part 15 interrupts | blocks both circuit breakers CB3 and CB4, the power consumption value of the power consumption apparatuses 11B, 11C, and 11D measured at the connection points B and C can be reduced.
The remote command information received from the control center 4 by the information receiving unit 16 only needs to include at least information related to the increase / decrease adjustment time zone in which the power consumption increase / decrease adjustment is to be performed. For example, the control unit 15 may determine in advance a circuit breaker to perform a shut-off operation, and actually perform the shut-off operation during the increase / decrease adjustment time period. In addition, the storage unit 23 of the power adjustment amount deriving device 20 stores a predetermined power consumption value that is reduced when the interruption operation is performed as described above (that is, a predetermined value of the power consumption device connected to the circuit breaker that is operated to be interrupted). Power consumption value) is stored in advance.

  As described above, in the present embodiment, if the remote command information is not received, a predetermined power consumption value is generated in the power consumption device 11 that is the target of the power consumption increase / decrease adjustment in the increase / decrease adjustment time zone, and the remote command If the information is received, it is assumed that the predetermined power consumption value generated in the power consuming apparatus 11 is reliably reduced in the increase / decrease adjustment time zone. For example, there is a lighting device (power consuming device 11) that is always lit if no remote command information is received, and the power supply to the lighting device is automatically shut off when the remote command information is received. A case is assumed.

  Therefore, in this embodiment, the power adjustment amount deriving device 20 operates when the information communication unit 21 that acquires at least information related to the increase / decrease adjustment time zone and the power consumption device 11 that is the target of the power consumption increase / decrease adjustment are operated. The storage unit 23 stores information related to the predetermined power consumption value, and the deriving unit 22 derives the power consumption amount derived from the product of the length of the increase / decrease adjustment time zone and the predetermined power consumption value as the power adjustment amount. Is configured to do. That is, in the above-described embodiment, the customer 10 is only encouraged to adjust the power consumption value voluntarily by using the output presentation unit 17. The power consumption apparatus 11 is configured such that the power consumption value is automatically controlled by the control unit 15. Therefore, the power adjustment amount deriving device 20 may consider that the predetermined power consumption value when the power consumption device 11 is operated is reliably reduced in the increase / decrease adjustment time zone.

  FIG. 5 is a graph for explaining a derivation example of the power adjustment amount in the customer 10. For example, FIG. 5 is a graph showing a predetermined power consumption value of the power consuming apparatus 11D that is an increase / decrease adjustment target device, and the power consuming apparatus 11D always operates while generating the predetermined power consumption value. Assumed. Therefore, if the control unit 15 performs the breaking operation of the circuit breaker CB4 during the increase / decrease adjustment time period, the predetermined power consumption value when the power consuming apparatus 11D is operated is reduced. As a result, even if the power consumption value at the connection point C is not measured, the power consumption amount derived by the deriving unit 22 from the product of the length of the increase / decrease adjustment time zone and the predetermined power consumption value is determined by the customer 10. It can be regarded as the power adjustment amount in the increase / decrease adjustment time zone.

<Another embodiment>

In the above embodiment, the value of the power adjustment amount by the customer 10 derived by the power adjustment amount deriving device 20 may be transmitted from the power adjustment amount deriving device 20 to the control center 4 via the communication line 3. Further, the value of the power adjustment amount by the customer 10 derived by the power adjustment amount deriving device 20 and the increase / decrease adjustment time zone included in the remote command information commanded from the control center 4 to the customer 10 regarding the power adjustment. The information may be associated and transmitted from the power adjustment amount deriving device 20 to the control center 4 via the communication line 3. As a result, the control center 4 can know how much the customer 10 corresponds to the transmitted remote command information (increase / decrease adjustment time zone). Then, the control center 4 may calculate a consideration according to the degree of the correspondence at the customer 10 and give the consideration to the customer 10.
