Embodiment 1 FIG.
FIG. 1 is a diagram illustrating a configuration example of a power control system including a power control apparatus 11 according to Embodiment 1 of the present invention. The power control system shown in FIG. 1 includes a DR server 10, a power control device 11, a power consuming device 12_i, and an environment detector 13_i. Here, i is a natural number from 1 to n.

  The DR server 10 is a server that is installed and operated on the power supply side, and transmits a DR that is a power reduction request to the power control device 11 that is installed on the power demand side. The power supply side is an operator that supplies power, and is typically an electric power company. Moreover, the electric power demand side is a person who consumes electric power, and can illustrate each household and store of a detached house and an apartment house.

  The power control apparatus 11 includes a communication unit 111, an information acquisition unit 112, a control DB (DataBase) 113, a processing unit 114, a control unit 115, and a display operation unit 116. The communication unit 111 is configured to be able to communicate with the DR server 10 and receives a DR from the DR server 10. The information acquisition unit 112 acquires environment information from the environment detector 13_i and acquires power consumption information from the power consumption device 12_i. The control DB 113 stores the control content of the power consuming device 12_i, the environment information of the control space to which the environment detector 13_i belongs, and the priority of the control content. The processing unit 114 monitors the amount of reduced power and resets the priority of control contents. The control unit 115 controls the power consuming device 12_i. The display operation unit 116 is configured to display the control content and priority, and to perform an operation for changing the control content and priority, and can be realized by a touch panel. However, the present invention is not limited to this, and the display unit and the operation unit may be provided separately. In the present specification, when the priority value is small, the priority is low, and when the priority value is large, the priority is high.

  The power consuming device 12_i is a device that improves the comfort of the control space installed on the power demand side. Examples of the power consuming device 12_i include, but are not limited to, an air conditioner, a ventilation fan, a heater, a humidifier, and a dehumidifier.

  The environment detector 13_i is a device that acquires environment information of a control space installed on the power demand side. Examples of the environment detector 13_i include a temperature sensor, a humidity sensor, and a human sensor, but are not limited thereto.

  An environment detector may be mounted on the power consuming device 12_i.

  Next, the operation of the power control system shown in FIG. 1 will be described. First, the DR server 10 transmits DR to the power control apparatus 11 via the communication network. Examples of DR include a power consumption reduction request indicating a target reduction amount, a power consumption reduction request indicating a target reduction ratio, and a power consumption reduction request indicating an upper limit consumption amount per unit time. Here, the value of the power consumption is the total value of the power consumed by the power consuming device 12_i connected to the power control device 11.

  When DR is a power consumption reduction request indicating the target reduction ratio, the target reduction amount can be obtained by multiplying the current power consumption by the target reduction ratio. When DR is a power consumption reduction request indicating the upper limit consumption per unit time, the target reduction amount can be obtained by subtracting the upper limit consumption from the current power consumption. The power control apparatus 11 may have a configuration that can calculate the target reduction amount.

  The communication unit 111 that has received the DR transmits information on the target reduction amount to the processing unit 114. On the other hand, the information acquisition unit 112 acquires environmental information represented by the room temperature and humidity of the control space from the environment detector 13_i, transmits the environmental information to the control DB 113, acquires the power consumption information of the power consumption device 12_i, and processes the processing unit. 114. Here, a power meter connected to the power consuming device 12_i is used to acquire the power consumption information. However, the present invention is not limited to this, and a power meter connected to a distribution board (not shown) may be used, or the power consumption of the entire power consuming device may be acquired.

  The control DB 113 stores the control content, control space information, and priority of the power consuming device 12_i at the time of power reduction.

  Here, the control content stored in the control DB 113 is control for reducing power consumption. In the case where the power consuming device 12_i is an air conditioner or a heater, examples include control for turning off the power, control for changing the set temperature, and control for suppressing the air volume. Here, the control for changing the set temperature to reduce power consumption is a control for increasing the set temperature during cooling operation and dry operation and decreasing the set temperature during heating operation. Or when power consumption apparatus 12_i is a humidifier and a dehumidifier, the control which turns off a power supply and the control which changes setting humidity can be illustrated. Here, the control for changing the set humidity is a control for decreasing the set humidity during humidification and increasing the set humidity during dehumidification, or when the power consuming device 12_i is a ventilation fan, the number of rotations per unit time. It is the control which lowers.

  The control space information stored in the control DB 113 is information on a space to which the power consuming device 12_i belongs, and includes information on a name, room temperature, set temperature, humidity, and set humidity. Examples of names included in the control space information include living room, dining room, and bedroom. The room temperature and the set temperature included in the control space information are represented by Celsius temperature [° C.], and the humidity and the set humidity included in the control space information are represented by relative humidity [RH%].

  Moreover, the priority memorize | stored in control DB113 shows the priority of each control content, and control of a power reduction operation | movement is performed from the thing with a low priority at the time of execution of power reduction. This priority is set on the power demand side, is determined based on the control space information so as to maintain the comfort of the control space, and is reset by the processing unit 114. The priorities at this time may all be different numbers, or the same number may be used. If the priority is all different numbers, the control contents are executed one by one from the smaller number and the lower priority, but the same priority is given if some of the priorities are the same number. The degree of control is executed at the same time.

  The processing unit 114 monitors the reduced power amount of the power consuming device 12_i. That is, when receiving the DR from the communication unit 111, the processing unit 114 refers to the information in the control DB 113, selects the control content with the lowest priority, and transmits it to the control unit 115. Then, the processing unit 114 compares the target reduction amount of DR received from the communication unit 111 with the reduction power amount calculated from the current power consumption received from the information acquisition unit 112, and the reduction power amount is the target reduction amount. If not reached, the control content with the next lowest priority is selected and transmitted to the control unit 115. When the power reduction amount reaches the target reduction amount, the control content with priority thereafter is not executed, and the process is terminated.

  Further, the processing unit 114 resets the priority according to the state of the space to which the power consuming device 12_i belongs. In a space where the difference between the room temperature and the set temperature is small, comfort is maintained even if control that reduces power consumption is performed, but in a space where the difference between the room temperature and the set temperature is large, control that reduces power consumption is performed. When run, comfort is compromised. That is, if the priority is reset with reference to the room temperature and the set temperature, the power consumption can be reduced without impairing the comfort. Similarly, regarding the humidity, if the priority is reset by referring to the humidity and the set humidity, the power consumption can be reduced without impairing the comfort.

  The control unit 115 executes control of the power consuming device 12_i according to the control content transmitted from the processing unit 114 for power reduction.

  The display operation unit 116 displays information of the control DB 113 on the screen, and can set the control content and priority of the power consuming device 12_i by an operation on the power demand side.

  Next, a specific example of the present embodiment will be described. FIG. 2 is a diagram illustrating a space to which the power control system in the first embodiment is applied. In FIG. 2, the control space 201, 202, 203, 204 and the air conditioner 211, the heater 212, the air conditioner 213, the humidifier 214, the dehumidifier 215, the air conditioner 216, and the dehumidifier corresponding to the power consuming device 12_i 217, temperature sensors 221, 222, 223 and humidity sensors 231, 232, 233 corresponding to the environment detector 13_i are shown. The control space 201 is a child room, the control space 202 is a bedroom, the control space 203 is a kitchen, and the control space 204 is a living room.

  First, the DR server 10 transmits a DR with a target reduction amount of 1000 W to the power control apparatus 11. The communication unit 111 that has received the DR transmits the DR to the processing unit 114. When receiving the DR from the communication unit 111, the processing unit 114 that has received the DR refers to the information in the control DB 113.

  FIG. 3 is a diagram illustrating a first table 300 that is an example of information in the control DB 113 according to the first embodiment. In the first table 300 shown in FIG. 3, the room temperature and humidity of the control space are determined by the information acquisition unit 112 using the temperature sensors 221, 222, 223 and humidity sensors 231, 232, 233 in the control spaces 201, 202, 203, 204. Information obtained from. In the first table 300 shown in FIG. 3, the name of the control space, the set temperature, the set humidity, the control content, and the priority are information input via the display operation unit 116 on the power demand side.

  Further, the processing unit 114 resets the priority according to the state of each space to which the power consuming device 12_i belongs. In resetting the priority, the urgency level of each control content is calculated, and the smaller the urgency value, the smaller the priority value. The urgency U is U = α × (priority set on the power demand side) / (number of priorities set on the power demand side) + (1−α) × (importance of temperature or humidity) / (Number of temperature or humidity steps). Here, (priority set on the power demand side) / (number of priorities set on the power demand side) is a value obtained by normalizing the priority set on the power demand side. Further, (importance of temperature or humidity) / (number of stages of temperature or humidity) is a value obtained by normalizing the importance calculated by the processing unit 114. The weighting coefficient α is set on the power demand side and is 0 or more and 1.0 or less. As for the reset priority, the value set by the power demand side has the highest priority when α = 1, and the importance calculated by the processing unit 114 has the highest priority when α = 0.

  The importance of temperature or humidity is determined by the difference between room temperature and set temperature or the difference between humidity and set humidity. FIG. 4 is a diagram illustrating the second table 400 and the third table 410 which are examples of information in the control DB 113 according to the first embodiment. In the second table 400 shown in FIG. 4, the importance is set in four stages, and the importance is higher as the difference between the room temperature and the set temperature is larger. Similarly, the third table 410 shown in FIG. 4 has four levels of importance, and the degree of importance increases as the difference between the humidity and the set humidity increases. Here, the threshold values of the difference between the room temperature and the set temperature in the second table 400 and the difference between the humidity and the set humidity in the third table 410 are values that can be set as appropriate. Also, the number of importance levels can be set as appropriate.

  In the example shown in FIGS. 3 and 4, the priority set on the power demand side is 1 to 7 and the importance is 1 to 4. Therefore, when the weighting coefficient α is 0.5, the air conditioner 211 is set. The priority U of the power demand side is “1”, the priority number “7” is set on the power demand side, the importance level “1” of temperature or humidity, and the temperature or humidity stage number “4”. U = 0.196. In this way, the urgency U of all the power consuming devices 12_i in the control space is calculated.

  FIG. 5 is a diagram illustrating a fourth table 500 that is an example of information in the control DB 113 according to the first embodiment. When calculated as described above, as shown in the fourth table 500, the urgency U = 0.196 of the air conditioner 211, the urgency U = 0.393 of the heater 212, and the urgency U = of the air conditioner 213 = 0.929, Urgency U of the humidifier 214 = 0.607, Urgent degree U of the dehumidifier 215 = 0.339, Urgent degree U of the air conditioner 216 = 0.750, Urgent degree U of the dehumidifier 217 = 0 .786.

  In addition, when resetting a priority from the urgent level U, it processes so that it may become the range of the original priority. As shown in FIG. 5, the number of priorities in the fourth table 500 is the original number of priorities “7”. The priority is reset such that the smaller the urgency U is, the smaller the numerical value of the priority is. Note that the priority resetting is not limited to when the DR is received, and may be periodically executed as an example every hour.

  As described above, after resetting the priority from the urgent level U, the processing unit 114 selects the control content with the smallest numerical value of the priority according to the reset priority and transmits it to the control unit 115. . Here, the processing unit 114 transmits control to turn off the air conditioner 211 to the control unit 115.

  The control unit 115 controls the power consuming device 12_i in accordance with the control content transmitted from the processing unit 114. Here, the control unit 115 turns off the air conditioner 211.

  When the processing unit 114 compares the target reduction amount of DR received from the communication unit 111 with the reduction power amount calculated from the current power consumption received from the information acquisition unit 112, the processing unit 114 does not reach the target reduction amount Then, the control content with the next lowest priority value is selected and transmitted to the control unit 115. As an example, if the target reduction amount is 1000 W and the reduction power amount calculated from the current power consumption is 500 W, the reduction power amount does not reach the target reduction amount. Therefore, the processing unit 114 selects the control content “change the set humidity of the dehumidifier 215 by 10% RH” with the next lowest priority value, and transmits it to the control unit 115. Then, the control unit 115 changes the set humidity of the dehumidifier 215 to 10% RH. When the power reduction amount reaches the target reduction amount, the control content with priority thereafter is not executed, and the process is terminated.

  When the priority is reset periodically, the control unit 115 executes the control content with a small priority value based on the reset priority, and the power reduction amount reaches the target reduction amount. Repeat power reduction until When the power reduction amount reaches the target reduction amount, the control content with priority thereafter is not executed, and the process is terminated.

  As described in the present embodiment, the power control apparatus that has received the DR, which is a power reduction request from the DR server, resets the priority based on the difference between the room temperature and the set temperature or the difference between the humidity and the set humidity. Then, execute the control content from the power consumption device with a small numerical value of priority, and when the target reduction amount is reached, the control content of the priority after that is not executed, and the power reduction of the power consumption device is terminated, The power consumption can be reduced so as to satisfy the power reduction request without impairing the comfort of the control space in which the power consuming device is operating.

Embodiment 2. FIG.
In the present embodiment, in addition to the first embodiment, a mode in which the presence of a person in the control space is detected and the priority is reset will be described. The configuration of the power control system in the present embodiment is the same as that in FIG. 1, but the environment detector 13_i includes a human sensor. Also in the present embodiment, the power control apparatus 11 that has received the DR from the DR server 10 calculates the urgency level U, resets the priority level from the magnitude of the urgency level U, and the priority level is small. The control content is executed from the power consuming device 12_i. In this embodiment, the presence information of the person in the control space is stored in the control DB, and the processing unit 114 adds the difference between the room temperature and the set temperature of the control space or the difference between the humidity and the set humidity. Urgent level U is calculated by detecting the presence of.

  Next, a specific example of the present embodiment will be described. FIG. 6 is a diagram illustrating a space to which the power control system in the second embodiment is applied. The configuration illustrated in FIG. 6 is a configuration in which human sensors 241, 242, 243, and 244 corresponding to the environment detector 13_i are added to the configuration illustrated in FIG.

  FIG. 7 is a diagram illustrating a fifth table 600 that is an example of information in the control DB 113 according to the second embodiment. In the fifth table 600 shown in FIG. 7, the room temperature and humidity of the control space are determined by the information acquisition unit 112 in the temperature sensors 221, 222, 223 and humidity sensors 231, 232, 233 in the control spaces 201, 202, 203, 204. The human sense of the control space is the information obtained from the human sensors 241, 242, 243, and 244.

  When receiving the DR from the communication unit 111, the processing unit 114 refers to the information in the control DB 113. Here, the table 600 is referred to. And the process part 114 calculates the urgency U of all the control content, compares the magnitude of the numerical value of the urgency U, and resets a priority. In resetting the priority, the urgency level of each control content is calculated, and the smaller the urgency value, the smaller the priority value. The urgency U is U = β × {α × (priority set by the power demand side) / (number of priorities set by the power demand side) + (1−α) × (importance of temperature or humidity) / (The number of stages of temperature or humidity)} + (1−β) × (presence / absence of a person in the control space) Here, the first term is the same as in the first embodiment. Regarding the second term, if there is a person in the control space (the presence or absence of a person in the control space) = 1, if there is no person (the presence or absence of a person in the control space) = 0. The weighting coefficient β is set on the power demand side and is 0 or more and 1.0 or less. As for the reset priority, the value set by the power demand side has the highest priority when β = 1, and the priority calculated by the processing unit 114 has the highest priority when β = 0. If β = 1, the reset priority is not reflected on the presence information of the person in the control space, and if β = 0, it is determined by the presence information of the person in the control space. The priority will be determined.

  Here, the urgency U is calculated using the tables 400 and 410 shown in FIG. 4 of the first embodiment and the table 600 shown in FIG. When calculating using the priority number “7” set on the power demand side, the number of temperature and humidity stages “4”, α = 0.5, β = 0.3, the air conditioner 211 has an urgency level U. = 0.3 * {0.5 * 1/7 + 0.5 * 1/4} + 0.7 * 1 = 0.759.

  FIG. 8 is a diagram illustrating a sixth table 700 that is an example of information in the control DB 113 according to the second embodiment. When calculated as described above, as shown in the sixth table 700, the urgency U = 0.759 of the air conditioner 211, the urgency U = 0.818 of the heater 212, and the urgency U = of the air conditioner 213 = 0.279, urgency level U = 0.182 of the humidifier 214, urgency level U = 0.101 of the dehumidifier 215, urgency level U = 0.925 of the air conditioner 216, urgency level U = 0 of the dehumidifier 217 .936.

  As described above, after resetting the priority from the urgent level U, the processing unit 114 selects the control content with the smallest numerical value of the priority according to the reset priority and transmits it to the control unit 115. . Here, the processing unit 114 transmits “change the set humidity to 10% RH” of the dehumidifier 215 to the control unit 115.

  The control unit 115 controls the power consuming device 12_i in accordance with the control content transmitted from the processing unit 114. Here, the control unit 115 changes the set humidity of the dehumidifier 215 to 10% RH. When the power reduction amount reaches the target reduction amount, the control content with priority thereafter is not executed, and the process is terminated.

  As described in the present embodiment, the power control apparatus that has received the DR, which is a power reduction request from the DR server, determines whether there is a difference between the room temperature and the set temperature or between the humidity and the set humidity and the presence of a person. The priority is reset, and the control details are executed from the power consumption device with the lower priority value. When the target reduction amount is reached, the priority control details after that are not executed and the power consumption of the power consumption device is reduced. Because the priority value of the space where there is no person is reduced, the power consumption can be reduced to satisfy the power reduction requirement without deteriorating the comfort of the control space where the person exists. .

Embodiment 3 FIG.
In the present embodiment, in addition to the first and second embodiments, a mode of storing a plurality of control contents of each power consuming device will be described. In this embodiment, the configuration of the power control system is the same as that in FIG. Also in the present embodiment, the power control apparatus 11 that has received the DR from the DR server 10 calculates the urgency level U, resets the priority level from the magnitude of the urgency level U, and the priority level is small. The control content is executed from the power consuming device 12_i. In the present embodiment, a plurality of control contents of each power consuming device are stored in the control DB, and fine control is realized for each power consuming device. At this time, the number of control contents set for each power consuming device need not be the same, and there is no upper limit to the number of control contents.

  Next, a specific example of the present embodiment will be described. In the present embodiment, the power control system shown in FIG. 6 is applied.

  FIG. 9 is a diagram illustrating a seventh table 800 that is an example of information in the control DB 113 according to the third embodiment. In the seventh table 800 shown in FIG. 9, the room temperature and humidity of the control space are determined by the information acquisition unit 112 using the temperature sensors 221, 222, 223 and humidity sensors 231, 232, 233 in the control spaces 201, 202, 203, 204. The human sense of the control space is the information obtained from the human sensors 241, 242, 243, and 244.

  When receiving the DR from the communication unit 111, the processing unit 114 refers to the information in the control DB 113. Here, the table 800 is referred to. As shown in the table 800, when a plurality of control contents are set for the same power consuming device, the priority value of the control contents with a small power reduction amount is reduced on the power demand side. That is, as the control contents of the air conditioner 213, “change the set temperature by 2 ° C.”, “change the set temperature by 5 ° C.” and “power off” are set, and among these, “change the set temperature by 2 ° C.” The power reduction amount is the smallest, and the power reduction amount of “power OFF” is the largest. Therefore, regarding the control contents of the air conditioner 213, the priority value of “change the set temperature by 2 ° C.” is minimized, and the priority value of “power OFF” is maximized.

  And the process part 114 calculates the urgency U of all the control content, compares the magnitude of the numerical value of the urgency U, and resets a priority. In resetting the priority, the urgency level of each control content is calculated, and the smaller the urgency value is, the smaller the priority value is. The degree of urgency U may be calculated as described in the first and second embodiments.

  Here, the urgency U is calculated using the tables 400 and 410 shown in FIG. 4 of the first embodiment and the table 800 shown in FIG. The calculation is performed in the same manner as in the first embodiment, using the number of priorities “15”, the number of stages of temperature and humidity “4”, and α = 0.5 set on the power demand side.

  FIG. 10 is a diagram illustrating an eighth table 900 that is an example of information in the control DB 113 according to the third embodiment. When the calculation is performed as described above, as shown in the eighth table 900, the priority for each control content is calculated for each control device.

  As described above, after resetting the priority from the urgent level U, the processing unit 114 selects the control content with the smallest numerical value of the priority according to the reset priority and transmits it to the control unit 115. . Here, the processing unit 114 transmits “change the set temperature by 3 ° C.” of the air conditioner 211 to the control unit 115.

  The control unit 115 controls the power consuming device 12_i in accordance with the control content transmitted from the processing unit 114. Here, the control unit 115 changes the set temperature of the air conditioner 211 by 3 ° C. When the power reduction amount reaches the target reduction amount, the subsequent priority control contents are not executed, and the process ends.
