This refers to the adapter 50 that executes the stop. This is because, when a plurality of power control devices 40 are provided in the consumer side facility 1, all the adapters 50 in the consumer side facility 1 are shared by each power control device 40 to perform power supply control. Therefore, this means that the adapter 50 for which the self-power control device 40 does not perform power supply control is excluded. However, in the present embodiment, only one power control device 40 is illustrated for convenience, and all adapters 50 of the customer-side equipment 1 are controlled, so in the following description, “power supply control target” The adapter 50 ”is simply referred to as“ adapter 50 ”.

The “power control device 40 that executes power supply control” refers to the power control device 40 that executes power supply control of the adapter 50 when there are a plurality of power control devices 40 in the customer-side facility 1. I mean. In the following description, it will be simply referred to as “power control device 40”. The input unit 52 inputs power from the outlet 9 into which the plug 61 is inserted. The output unit 53 supplies power to the electrical device 8 inserted into the outlet 62. The measuring unit 54 measures the amount of power used in the electrical device 8. In the present embodiment, it is only necessary to measure the total amount of power used by the electrical device 8 connected to the own adapter 50, but it may be measured individually and the measured value may be held and managed. Under the control of the control unit 58, the control switch unit 55 performs energization / cutoff from the input unit 52 to the output unit 53 by connecting / disconnecting the wiring. The setting unit 56 sets a priority for the adapter 50. The setting unit 56 may be realized by software or may be realized by switch means such as a dip switch.

The notification unit 57 is provided as a usage record notification unit, and indicates the amount of power used in the adapter 50 measured by the measurement unit 54, specifically, the amount of power used by one or more electrical devices 8 connected to the own adapter 50. The power usage record information including the date and time information for specifying the measurement date and time of the total power consumption is transmitted to the power control device 40 via the wireless communication unit 51 to notify the power usage record in the adapter 50. The notification unit 57 is also provided as a priority notification unit, and notifies the priority set in the adapter 50 by transmitting it to the power control device 40 via the wireless communication unit 51. The control unit 58 operates in cooperation with the components 51 to 58 in the adapter 50 to realize functions in the adapter 50. In particular, the control unit 58 in the present embodiment is provided as a control unit, and when receiving the stop instruction information transmitted from the power control device 40, the priority determined by the power saving target determination unit 43 is set in itself. If it is, the supply of power to the connected electrical device 8 is stopped at the timing of starting power saving. In addition, when the start instruction information transmitted from the power control device 40 is received and the priority determined by the power saving target determining unit 43 is set for itself, the connection is made at the timing of the end of power saving. Start supplying power to the electrical equipment.

  Each of the components 51 to 59 in the adapter 50 is performed in cooperation with a computer mounted on the adapter 50 and a program operating on a CPU mounted on the computer, and as described above, together with the plug 61, the outlet 62 or the switch. Realized. The storage unit 60 is realized by a RAM mounted on the adapter 50.

  Further, the program used in this embodiment can be provided not only by communication means but also by storing it in a computer-readable recording medium such as a CD-ROM or DVD-ROM. A program provided from a communication means or a recording medium is installed in a computer, and various processing functions are realized by the CPU of the computer executing the program.

  Next, the operation in this embodiment will be described. First, a description will be given of preparations that should be made in implementing this embodiment.

  In the present embodiment, first, a priority is set for the adapter 50. In this embodiment, as an example, three levels of priority can be set. When it is predicted that the amount of power supply will be insufficient in a certain time zone, power is saved by stopping the power supply to the electrical equipment in that time zone, but priority 1 with the highest priority is power saving This is a priority suitable for connecting the electrical equipment 8 that is desired to continue to be operated until the end. On the other hand, priority 3, which is the lowest priority, is a priority suitable for connecting an unnecessarily urgent electric device 8 that power supply may be stopped during power saving. Priority 2 positioned between priority 1 and priority 3 is not as high as continuous power supply as priority 3 if priority is given to what should be operated as much as possible even during power saving. This priority is suitable for connecting electrical equipment. Note that the number of priority levels (stages) is not limited to this example. On the contrary, 1 may be the lowest priority.

  The manager or user of the electrical equipment or electrical equipment in the customer side equipment 1 connects the electrical equipment 8 with reference to the priority set in the adapter 50, or according to the electrical equipment 8 already connected. An appropriate priority is set for the adapter 50. For example, it is desirable to connect the guide light, medical device, etc. of the customer side equipment 1 to the adapter 50 of priority 1. Further, it is desirable to connect general lighting or the like to the adapter 50 of priority 2. In addition, it is desirable to connect entertainment related devices such as televisions and games, and preference-related devices to the adapter 50 of priority 3. When a priority is set for each adapter 50, the set priority of each adapter 50 is registered in each storage unit 60.

  In the following description, the case where three adapters A, B, and C are prepared in the customer side facility 1 and the priorities 1, 2, and 3 are set for each of the adapters will be described as an example. In the following description, the description common to the three adapters A, B, and C may be referred to as “adapter 50”. In addition, only “Adapter A”, “Adapter B”, and “Adapter C” are individually described in terms of contents unique to each adapter. In this example, for convenience of explanation, both the number of priorities and the number of adapters 50 are set to 3 and different priorities are set for the respective adapters 50. However, it is necessary to give dependency to the priorities and the number of adapters 50. There is no. The same priority may be set for different adapters 50.

  Next, the operation | movement at the time of normal operation in the consumer side equipment 1 is demonstrated.

  When the prior preparation for setting the priority is completed, there is no need to save power while the power supply amount is not insufficient. Therefore, the control unit 58 in each adapter 50 instructs the control switch unit 55 to input the input unit 52. And the output unit 53 are connected. In other words, the electric device 8 connected to the adapter 50 is in a usable state by being supplied with electric power. The measurement unit 54 constantly measures the amount of power used in the adapter 50, but the notification unit 57 uses the amount of power used at the time point measured by the measurement unit 54 at a predetermined cycle, for example, every 30 minutes, and the use. Power usage record information including date and time information for specifying the measurement date and time of the electric energy is generated. In addition, the notification unit 57 reads the set priority from the storage unit 60, identifies its own adapter 50 identification information (in this example, “A”, “B”, or “C”), the read priority, Then, the adapter information indicating the current adapter status is transmitted to the power control apparatus 40 in combination with the usage record information.

  When adapter information is transmitted from the adapter 50, the information registration unit 45 in the power control device 40 registers the adapter information in the adapter information storage unit 47.

  A data configuration example of adapter information registered in the adapter information storage unit 47 by the information registration unit 45 is shown in FIG. As shown in FIG. 6, the adapter information includes the identification information (adapter ID) of each adapter, the priority set for the adapter 50, and the power consumption and date / time information in the adapter 50 obtained from the usage record information. Are associated with each other. The adapter information is registered and accumulated in the adapter information storage unit 47 each time it is transmitted.

  In the present embodiment, the priority and the power usage record information are always integrated and transmitted to the power control apparatus 40. However, the priority is newly set separately from the use record information, for example. Alternatively, it may be transmitted separately at the changed timing.

  Next, processing related to power supply control in the present embodiment will be described. First, the processing in the management server 30 will be described using the flowchart shown in FIG.

  In FIG. 7, the power saving information generation unit 33 in the management server 30 receives the predicted supply value sent from the shipping power facility 2 and reads out the predicted demand value stored in the storage unit 36 to thereby predict each predicted value. Is acquired (step 101). The predicted supply value is obtained from the power supply capability of the shipping power facility 2 at the current time. Each predicted value may be appropriately corrected as described above. Each predicted value handled in the present embodiment may be data obtained by a certain method.

  Here, the power saving information generation unit 33 compares the supply predicted value with the demand predicted value (step 102), and predicts that the power supply amount is insufficient due to the supply predicted value being lower than the demand predicted value (in step 103). Y) The time zone predicted to be deficient is specified and the deficiency is calculated (step 104). Specifically, the ratio that requires power saving is calculated by the following formula: | supply prediction value−demand prediction value | / demand prediction value × 100. Here, for example, if it is predicted that the power supply amount between 10:00 and 14:00 will be 10% short, the power saving information generation unit 33 generates power saving information indicating that fact. Note that the shortage may not be a ratio, but a deficient power supply amount may be obtained. Thus, the power saving target for the power demand side as a whole is set in the power saving information. The power saving request unit 34 that has received the power saving information generated by the power saving information generating unit 33 generates power saving request information based on the power saving information (step 105).

  FIG. 8 is a diagram showing an example of the data configuration of the power saving request information in the present embodiment. The power saving request information is configured by associating an identification code for identifying a power supply control instruction and a control command corresponding to the instruction with instruction information indicating the content of a specific instruction. As shown in this example, the instruction information in the case of a power saving request (SAVE_REQUEST) includes date and time information including the date and time zone (start time and end time) for power saving, and the power saving target value as the power saving target value. A percentage is included.

  The power saving request unit 34 requests each customer side facility 1 to save power by distributing the generated power saving request information to each power control device 40 installed in each customer side facility 1 via the communication unit 32. (Step 106).

  If it is predicted that the amount of power supply will not be insufficient (N in step 103), the power saving instruction is naturally not distributed, but the fact that there is no need for power saving may be distributed to each power control device 40. .

  Next, processing in the power control apparatus 40 will be described using the flowchart shown in FIG.

  When the power saving request information sent from the management server 30 is acquired via the communication unit 41 (step 121), the power saving target determining unit 43 analyzes the power saving request information from 10:00 on March 31, 2012. It is recognized that the instruction content is to save 10% by 14:00 (step 122). Next, the power saving target determining unit 43 determines how much the electrical device 8 connected to the adapter 50 of which priority is used from the priority and usage record information stored in the adapter information storage unit 47. It is calculated whether or not power saving of the ratio is possible (step 123). That is, the power saving effect due to the power supply stoppage is obtained by calculation. Here, a calculation method will be described using the values illustrated in FIG.

  Based on the usage record information illustrated in FIG. 6, the total power consumption of the adapters A, B, and C is 60 + 100 + 100 = 260. Here, the power saving when the power supply to the priority level 3 having the lowest priority level is stopped is a priority level 1 or 2 in which power can be continuously used from 1 (100%) to the total power consumption. A value obtained by subtracting the ratio of the amount of power used, that is, 1− (60 + 100) /260=0.38=38%. That is, it is possible to obtain a power saving effect of 38% with respect to the power saving requirement of 10%.

  By the way, for power saving when power supply up to priority 2 is stopped, subtract the ratio of power consumption of priority 1 that can be used continuously from 1 (100%) to the total power consumption Value, that is, 1-60 / 260 = 0.77 = 77%. In other words, it is possible to obtain a power saving effect of 77% with respect to 10% of the power saving requirement. The power saving when the power supply up to priority 1 is stopped is 100%.

  From the above, it can be understood that by stopping the power supply up to priority 3, it is possible to meet the required 10% power saving. The adapter information used for calculating the power saving effect can accurately calculate the power saving effect when the power supply is stopped by using, for example, the information of the same time of the previous day, the same time of the previous day, or the same day of the previous year. Like that.

  As described above, when it is determined to what level the priority level adapter 50 should stop supplying power (step 124), the control instruction unit 44 determines the power saving start timing (2012 3). Stop instruction information including priority = 3 is generated by 10:00 on March 31, and a stop instruction is issued by transmitting the stop instruction information to each adapter 50 when power saving timing comes (step 125).

  Next, processing in the adapter 50 will be described using the flowchart shown in FIG.

  When the instruction information sent from the power control device 40 is acquired via the wireless communication unit 51 (step 141), the control unit 58 reads the priority set in the storage unit 60, and the read priority and Then, the priority included in the instruction information is compared (step 142), and it is determined whether or not it is the target of the control instruction. If it is determined that the user's priority is higher than the priority included in the instruction information and that the user is not subject to the control instruction (N in step 143), the process is terminated. In other words, the wiring between the input unit 52 and the output unit 53 remains connected without being cut off, and the electric device 8 can be used continuously. In this example, the adapters A and B are priorities 1 and 2, so this is the case. On the other hand, if the priority included in the instruction information is 3 or less and it is determined that it is the target of the control instruction (Y in step 143), the content of the acquired instruction information is confirmed (step 144). In this example, the adapter C with the priority 3 corresponds to this case. When the acquired instruction information is stop instruction information (Y in Step 145), the control unit 58 instructs the control switch unit 55 to block the wiring between the input unit 52 and the output unit 53, and connect The supply of electric power to the electrical device 8 is stopped (step 146).

  By operating as described above, the customer-side equipment 1 can save 38% of power, so that it is possible to achieve power saving more than the power saving effect of 10% requested from the power supply side.

  In FIG. 9, after stopping the supply of power in the adapter C, when the end time of the time zone in which the power saving is requested (in this example, 13:00 on March 31, 2012), the control instruction unit 44 The start instruction information including priority = 3 is generated by the end timing of the connection, and when the power saving end timing is reached, the start instruction information is transmitted to each adapter 50 to issue a connection instruction (step 126).

  In FIG. 10, when the instruction information sent from the power control device 40 is acquired via the wireless communication unit 51 (step 141), the control unit 58 reads the priority set in the storage unit 60 and reads the priority. The priorities and the priorities included in the instruction information are compared (step 142), and it is determined whether or not the subject is subject to the control instruction. If it is determined that the user's priority is higher than the priority included in the instruction information and that the user is not subject to the control instruction (N in step 143), the process is terminated. This is because the power supply to the connected electrical device 8 has already been performed. On the other hand, if the priority included in the instruction information is 3 or less and it is determined that it is the target of the control instruction (Y in step 143), the content of the acquired instruction information is confirmed (step 144). When the acquired instruction information is start instruction information (N in Step 145, Y in Step 147), the control unit 58 instructs the control switch unit 55 to wire between the input unit 52 and the output unit 53. To start supplying power to the connected electrical equipment 8 (step 148). If the acquired instruction information is neither stop instruction information nor start instruction information (N in step 147), the process ends because it is not applicable to the present embodiment, but error processing is performed assuming that unrecognizable information has been received. May be implemented.

  In the above description, the instruction information is transmitted to all the adapters A, B, and C to be controlled by the power control apparatus 40, but the priority is 3 or less with reference to the adapter information storage unit 47 ( In this example, only 3) may be specified as the adapter C, and the instruction information may be transmitted only to the adapter C. In this case, since the adapter 50 that has received some instruction information can recognize that it is the target of the control instruction by receiving the instruction information, it determines whether it is the target of the control instruction by comparing the priorities. The processing (steps 142 and 143) to be performed may be omitted.

  In the present embodiment, the power control device 40 is provided with time measuring means (not shown), and the instruction information is transmitted to the power control device 40 at the start / end timing of power saving. May be provided to the adapter 50. In this case, the power control apparatus 40 immediately transmits the generated instruction information to the adapter 50, makes the adapter 50 wait until the power saving start / end timing included in the instruction information, and stops or starts the supply of power. You may make it control.

Embodiment 2. FIG.
In the first embodiment, the power supply is stopped so that each customer-side facility 1 achieves the power saving target with respect to the power saving target of 10%. Regarding the operation in the first embodiment, consider the case where there are a plurality of customer-side facilities 1.

  FIG. 11 is a configuration diagram showing a main part of the power usage control system in the present embodiment. In the present embodiment, a plurality of customer-side facilities 1 such as a building A and a building B are illustrated. Since the other configuration is the same as that of the first embodiment, it is omitted.

  FIG. 12A is a diagram illustrating a data configuration example of adapter information registered in the adapter information storage unit 47 in the power control device 40 provided in the building A. FIG. 12B is a diagram illustrating a data configuration example of adapter information registered in the adapter information storage unit 47 in the power control device 40 provided in the building B.

  Here, it is assumed that a power saving target of 10% is distributed to each of the buildings A and B as in the first embodiment. 12A is the same value as the adapter information in the first embodiment although the adapter ID of the adapter 50 is different, the specific content of the calculation is omitted, but the power saving when the power supply up to priority 3 is stopped is 38. The power saving when the power supply up to priority 2 is stopped is 77%. Therefore, in order to meet the power saving target of 10%, the power supply should be stopped in the adapter A03 with the priority 3.

  On the other hand, in the building B, the total power consumption of the adapters B01, B02, and B03 is 100 + 180 + 20 = 300. Here, the power saving when the power supply up to the lowest priority 3 is stopped is 1− (100 + 180) /300=0.07=7% as in the first embodiment. That is, only 7% of power saving effect can be obtained for 10% of power saving demand.

  Subsequently, the power saving when the power supply up to priority 2 is stopped is 1-100 / 300 = 0.67 = 67%. That is, it is possible to obtain a power saving effect of 67% with respect to the power saving requirement of 10%.

  From the above, in order to meet the power saving target of 10%, the adapter A03 in the building A and the adapters B02 and B03 in the building B are to be stopped from supplying power.

  Here, when the power saving effect is calculated by combining the buildings A and B, the total power consumption is 260 + 300 = 560, and the power saving power consumption is 100 + 20 + 180 = 300, so 300/560 = 0.54 = 54. % Power saving effect can be obtained. That is, when trying to achieve the power saving target for each customer-side facility 1, there is a possibility that an unnecessary power saving effect may be obtained. As is well known, electricity cannot be stored, so there is no point in saving too much power, and there may be various adverse effects such as inconvenience in daily life. Therefore, in the present embodiment, the management server 30 can be adjusted to achieve the target power saving.

  FIG. 13 is a block configuration diagram of the power control apparatus 40 in the present embodiment. In addition, the same code | symbol is attached | subjected to the same component as Embodiment 1, and description is abbreviate | omitted. As shown in FIG. 13, the present embodiment has a configuration in which an information transmission unit 48 is added to the first embodiment. The information transmission unit 48 is provided as adapter information transmission means, and transmits the adapter information stored in the adapter information storage unit 47 to the management server 30. The information transmitting unit 48 is provided as a power saving schedule information transmitting unit, and determines the priority determined by the power saving target determining unit 43, the priority set for each adapter to be a power supply control target, and the amount of power used. The power saving schedule information including the specified information is transmitted to the management server 30. In the present embodiment, by transmitting the priority determined by the power saving target determining unit 43 together with the adapter information stored in the adapter information storage unit 47, the adapter information is “the power supply control target each adapter. It is handled as information corresponding to “power saving schedule information including information specifying the priority and power consumption set in“. If the adapter information is separately transmitted, the information transmitting unit 48 operating as the power saving schedule information transmitting unit may transmit the power saving schedule information including at least the priority determined by the power saving target determining unit 43.

  The configuration of the adapter 50 may be the same as that of the first embodiment. Further, as will be described later, the management server 30 differs from the first embodiment in the content of the processing in the power saving request unit 34, but the configuration may be the same as the first embodiment.

  Next, the operation in this embodiment will be described. FIG. 14 is a flowchart showing processing in the management server 30 and FIG. 15 is processing in the power control device 40 regarding power supply control in the present embodiment. In each figure, the same processes as those in the first embodiment are given the same step numbers, and description thereof will be omitted as appropriate.

  In FIG. 14, the management server 30 generates the power saving information indicating the power saving target by calculating the shortage of the power supply amount in the same manner as in the first embodiment, and in response to this, the power saving request unit 34 displays the power saving instruction information. Power saving is instructed by distributing to buildings A and B (steps 101 to 106).

  In FIG. 15, when the power saving instruction information is sent, in the power control devices 40 in the buildings A and B, in order to achieve the power saving target indicated by the power saving instruction information, The priority of the adapter 50 for stopping the power supply is determined (steps 121 to 124). In this embodiment, the information transmission unit 48 reads the adapter information from the adapter information storage unit 47, and generates power saving schedule information including the adapter information and the priority determined by the power saving target determining unit 43. And transmitted to the management server 30 (step 221). Note that the adapter information to be sent to the management server 30 does not need to be the current power consumption amount, and may send an appropriate power consumption amount for determining the priority for each of the buildings A and B as will be described later. Good.

  In FIG. 14, when the power-saving schedule information sent from all the buildings A and B is acquired via the communication unit 32 (step 201), the power-saving request unit 34 refers to the acquired power-saving schedule information, and the building A, The adapter 50 which should stop supply of electric power for every B is verified. A more appropriate priority is given to building A. Each B is determined (step 202). This process will be described below.

  Here, description will be made using the values exemplified above. That is, the power saving schedule information including the adapter information and priority 3 shown in FIG. 12A is acquired from the building A, and the power saving schedule information including the adapter information and priority 2 shown in FIG. 12B is acquired from the building B. To do.

  First, the power saving request unit 34 calculates a case where the supply of power is stopped only to the lowest priority 3 electric device 8 in all the buildings A and B in order to ensure fairness. Here, when the power saving effect is calculated for the buildings A and B together, the total power consumption is 260 + 300 = 560, and the power saving power consumption is 100 + 20 = 120, so 120/560 = 0.21 = 21. % Power saving effect can be obtained.

  In other words, regarding the building B, when it is necessary to individually achieve the power saving target, it is necessary to stop the supply of power to the electric equipment 8 up to priority 2, but the calculation is performed for the entire facility 1 on the consumer side. It can be seen that the power saving target of 10% can be achieved as a whole simply by stopping the supply of power to the electrical devices 8 up to priority 3. Therefore, the power saving request unit 34 in the present embodiment does not instruct the buildings A and B as they are for the power saving target of 10% generated by the power saving information generation unit 33, but as described above for each building A and B. As a result of reviewing the priorities, for the building B, power saving request information is generated to the effect that the power supply up to priority 3 instead of priority 2 may be stopped.

  FIG. 16 is a diagram illustrating an example of a data configuration of power saving request information according to the present embodiment. The data structure of the power saving request information is basically the same as that of the first embodiment, and the identification code identifying the power supply control instruction and the control command are associated with the instruction information indicating the specific instruction content. Configured. As in this example, the instruction information in the case of a priority change instruction request (SAVE_PRIORITY) includes date and time information including the date and time (start time and end time) for power saving and the priority to be changed. It is.

  The power saving request unit 34 instructs the change of the priority by distributing the power saving request information generated in this way to the power control device 40 installed in the building B via the communication unit 32 (step 203). Note that the power saving request information for instructing priority change is also referred to as “priority instruction information” in the present embodiment.

  In FIG. 15, after transmitting the power saving schedule information, the power control apparatus 40 waits for the priority change instruction from the management server 30 until the power saving start timing specified by the power saving request information acquired in step 121. (N in step 222, N in step 224). When the power saving request information (priority instruction information) corresponding to the priority change instruction is received from the management server 30 (Y in step 222), the power saving target determining unit 43 replaces the priority 2 determined in step 124. Then, by adopting priority 3 included in the received priority instruction information, the priority determined in step 124 is changed (step 223). And the control instruction | indication part 44 of the power control apparatus 40 in the building B produces | generates the stop instruction | indication information containing the priority 3 by the timing (March 31, 2012 10:00) of a power-saving start, and a power-saving timing The stop instruction is issued by transmitting the stop instruction information to each adapter 50 (step 125). When the priority instruction information from the management server 30 is not received before the power saving start timing (Y in step 224), the control instruction unit 44 displays the stop instruction information including the priority 2 A stop instruction is issued by generating and transmitting to each adapter 50 (step 125).

  According to the present embodiment, as described above, the priority determined in each customer-side facility 1 by the management server 30 is reviewed, and adjustment of the power supply stop is performed so as not to save power more than necessary as a whole. be able to.

  In the present embodiment, the priority determined in the management server 30 is transmitted as a change instruction only to the building B whose priority is to be changed. For the purpose of notification, power saving request information including priority information for specifying priority may be transmitted to all buildings A and B. In this case, in the building A, the priority received in step 222 and the priority determined in step 124 coincide with each other, so that it is not necessary to specifically respond to the priority change instruction. That is, the power saving target determining unit 43 determines the priority of the adapter 50 that stops the power supply in accordance with the priority information received in step 222. The priority specified by the priority information included in the power saving request information is, for example, 3 when priority information includes “3”, but includes “2” as priority information. 2 and 3 are shown.

  In this embodiment, the adapter information is transmitted together with the priority in step 221, but it is not always necessary to transmit the adapter information together. For example, the power control device 40 may transmit the adapter information to the management server 30 every time it receives adapter information from the adapter 50, or may transmit the adapter information together at regular intervals separately from the priority. Good. In this case, when the management server 30 receives the power saving schedule information including the priority in step 201, in step 202, the adapter information having the appropriate date and time for reviewing the priority is selected from the adapter information already received. The process for determining the priority is executed.

Embodiment 3 FIG.
In each of the above embodiments, a description has been given assuming a general Internet as a communication network between the management server 30 and the power control apparatus 40. However, in this embodiment, a network having a region specifying function is used. To do. For example, a network such as a mobile phone or a PHS communication network has a communication area on a cell centering on a radio base station, and therefore can transmit power saving request information to a specific base station. As a result, it is possible to save power only in specific areas where power supply capacity is insufficient. In addition, traffic on the communication network can be reduced.

  For example, in the second embodiment, since adapter information including the amount of power used is collected from each customer side facility 1, the information transmission unit 48 is a demand in which the adapter 50 is provided in the collected adapter information. The area specifying information for specifying the area where the person-side facility 1 is located is added and transmitted. The power saving request unit 34 in the management server 30 of the present embodiment is further provided as area specifying information acquisition means, and acquires area specifying information. In the case of the present embodiment, it is obtained by receiving the area specifying information sent from the power control device 40. And the power saving request | requirement part 34 specifies the area | region which requests | requires power saving by referring adapter information and area | region specific information, and uses the adapter 50 provided in the consumer side equipment 1 contained in the specified area | region as electric power. Power saving request information is transmitted to the power control apparatus 40 to be supplied and controlled.

  According to the present embodiment, it is possible to specify the customer-side equipment 1 included in the area where the effect of power saving can be expected instead of the entire area in this way and request power saving.

Embodiment 4 FIG.
The adapter 50 in each of the above embodiments is configured to send the measurement value of the power consumption in the adapter 50 to the power control device 40 at regular intervals, but the power consumption to be sent is the power consumption at the time of transmission. It is a measured value. By the way, in some electric appliances 8, the power consumption changes greatly during operation. For example, a PC or the like may enter a sleep mode depending on settings, but if the amount of power used during operation in the sleep mode is transmitted to the power control device 40, an error is likely to occur when determining the priority. turn into.

  Therefore, in the present embodiment, the measurement value of the power consumption at the time of transmission is not transmitted, but the power consumption measured by the measurement unit 54 is accumulated in the storage unit and sent to the power control device 40. The power consumption may be obtained by calculation based on the accumulated power consumption. For example, the maximum value of power consumption within a certain period is used.

  The above calculation may be performed not by the adapter 50 but by the power control device 40. When the above calculation is performed by the adapter 50, the adapter information storage unit 47 stores adapter information in which the maximum value of the power consumption is the power consumption of the adapter 50. When the above calculation is performed by the power control device 40, the adapter information storage unit 47 stores the measurement value, and the power saving target determination unit 43 extracts the adapter information within a certain period stored in the adapter information storage unit 47. Then, adapter information is generated in which the maximum power consumption amount included in the adapter information is used in the adapter 50, and the priority is determined by referring to the generated adapter information. The management server 30 may also transmit the maximum value of the power consumption within a certain period as adapter information.

  According to the present embodiment, errors in priority determination in the power control device 40 and the management server 30 can be made difficult to occur as described above. As a result, it is possible to reduce the amount of power used more effectively.

  In addition, you may use the average value of the used electric energy in a fixed period instead of the maximum value of the used electric energy.

Embodiment 5 FIG.
In each of the above embodiments, it is not assumed that the electric device 8 connected to the outlet 62 of the adapter 50 is replaced with another electric device 8. Therefore, if the electric device 8 is replaced, the electric device before replacement is assumed. The priority is determined and the power saving effect is calculated by using the power consumption amount corresponding to 8.

  Therefore, in the present embodiment, detection means for detecting insertion / removal of the electric device 8 is provided. In the present embodiment, the output unit 53 of the adapter 50 is provided with a detection function for detecting insertion / removal to / from the outlet 62, and when the insertion / removal of the electrical device 8 is detected, the amount of power used based on the electrical device 8 is determined. The actual value is deleted. In other words, the power control device 40 is notified that the insertion / extraction of the electrical device 8 has been detected, and the adapter information of the adapter 50 stored in the adapter information storage unit 47 of the power control device 40 is deleted. Or according to the notification of insertion / extraction of the electric equipment 8, it is not necessary to delete the adapter information of the said adapter 50 received before notification. In this case, when the power saving target determination unit 43 in the power control device 40 receives a notification to that effect from the adapter 50 in which the insertion / extraction of the electrical device 8 is detected, refer to the adapter information before notification corresponding to the adapter 50. The priority for stopping the power supply is determined.

  According to the present embodiment, if the insertion / extraction of the electric device 8 is not detected, the priority value is determined and the maximum electric power consumption is calculated using the actual value of the used electric energy, while the electric device 8 is inserted / removed. If detected, the determination of the priority and the calculation of the maximum power consumption using only the actual value of the power consumption after detection is performed. The actual value can be used properly. As a result, it is possible to reduce the amount of power used more effectively.

Specifically, the power saving target determining unit 43 in the power control device 40 is an adapter that performs power saving in accordance with the power saving target included in the power saving instruction information transmitted from the management server 30 via the communication unit 41. A priority of 50 was determined and power was saved. However, you may enable it to implement power saving voluntarily in the customer side equipment 1 even if there is no request | requirement from an electric power company.

  For example, user interface means (mouse 26, keyboard 27, etc. in FIG. 2) is connected to the power control device 40, and specified by the user using the user interface means instead of the power saving instruction information sent from the management server 30. There is provided a receiving means for receiving the power saving request information including the power saving target in all the adapters 50 which are the power saving targets and are subject to power supply control. The power saving target determining unit 43 may determine the priority of the adapter 50 that performs power saving in order to achieve the power saving target included in the received power saving request information.

  According to the present embodiment, each customer-side facility 1 can perform spontaneous power saving for the purpose of saving or the like.
