[1. About power consumption reduction device]
The power consumption reduction support device according to the embodiment of the present invention is intended to suppress the power consumption of the load facility by executing operation control on the load facility that controls the environment of the living space.

FIG. 1 is a functional block diagram showing a basic configuration of a power consumption reduction support apparatus 100 according to the present embodiment.
As illustrated in FIG. 1, the power consumption reduction support apparatus 100 includes a storage unit 110, a derivation unit 120, a calculation unit 130, an extraction unit 140, a display unit 150, and a parameter reflection unit 160. -1 and the lighting equipment 10-2 reflect the operation parameters. The air conditioning equipment 10-1 and the lighting equipment 10-2 will be collectively described as “load equipment 10” below.

The storage unit 110 stores the operation parameters related to the operation state of the load facility 10 operating to control the environment state in the living space and the power consumption of the load facility 10 via an interface unit (not shown). Are acquired from the load facility 10, and the acquired operation parameters and the power consumption of the load facility 10 are stored in the storage unit 110 as performance data.
In some cases, static data initially determined may be stored in a correspondence table between operation parameters and power consumption.

  In the present embodiment, for example, when the parameter of the set room temperature of the space that is air-conditioned and managed by the air conditioning equipment 10-1 is set at 24 ° C., the storage unit 110 stores the power consumption amount of the air conditioning equipment 10-1. Obtain actual values regularly. Thus, the storage unit 110 periodically acquires the actual power consumption amount value of the air conditioning equipment 10-1 corresponding to the set room temperature parameter, and associates the set room temperature parameter with the actual power consumption value. Memorized performance data. In addition, when the storage unit 110 acquires the operation parameter of the load facility 10 and the actual value of the power consumption, the environment of the living space such as the current value such as the indoor temperature and the external temperature of the living space held by the load facility 10 is obtained. Information representing the state (hereinafter referred to as “environment information”) can also be acquired at the same time.

  Next, the deriving unit 120 derives relationship information representing the relationship between the power consumption amount of the load facility 10 and the operation parameters based on the actual data stored in the storage unit 110. Further, the deriving unit 120 sets the operating condition of the load facility 10 so as not to exceed the upper limit value of the power consumption amount of the load facility 10 from the upper limit value and the actual data of the power consumption amount of the load facility 10 stored in advance. The operating condition information to be expressed is also derived.

The relation information is information representing a relation between an operation parameter of the load facility 10 and an amount of power consumption of the load facility 10 when operating with this parameter. In the present embodiment, the relationship between the operation parameter and the power consumption constructed based on the accumulated performance data of the operation parameter of the load facility 10 and the power consumption of the load facility 10 acquired by the storage unit 110. The deriving unit 120 derives information representing the relationship information.
Such relationship information can represent the relationship between the operation parameter and the power consumption by an arithmetic expression or a correspondence table.

As a specific example, the relationship information representing the relationship between the operation parameter for the air conditioning equipment 10-1 and the power consumption will be described.
When the set temperature of the living space is relaxed by 1 ° C., the power consumption of the air conditioning equipment can obtain a power reduction effect corresponding to the load reduction due to the relaxation of the set temperature. It is known that this power reduction effect, that is, the relationship between the operating parameter (set temperature) of the air conditioning equipment 10-1 and the power consumption varies depending on the outside air enthalpy. The outdoor enthalpy is determined by temperature and humidity, and is generally a value predicted from weather forecast data or actually measured physical quantities.

Here, in this Embodiment, the relationship information of the air conditioning equipment 10-1 based on the accumulate | stored performance data shall be represented by the following (Formula 1).
T (p) = a × p + b (Equation 1) where T is the set temperature, p is the electric energy, and a and b are coefficients (natural numbers).

  The coefficients a and b in (Equation 1) vary according to the outside air enthalpy. In the present embodiment, a correspondence table between the outside air enthalpy and the coefficients a and b of (Equation 1) is stored in the storage unit 110 in advance. The deriving unit 120 obtains the coefficients a and b corresponding to the predicted outside air enthalpy from the above correspondence table stored in advance, and derives (Equation 1), which is the relationship information of the air conditioning equipment 10-1 based on the actual data. To do.

In addition, the operating condition information is information that represents the operating condition of the load equipment required to achieve the target value when performing power demand control for achieving the target power consumption amount for the load equipment. It is.
In the present embodiment, the operating condition information is obtained from the environmental information of the living space and the current power consumption of the load facility 10 included in the actual data when the power consumption of the load facility 10 may exceed the upper limit. The information includes a reduction amount of the power consumption necessary for preventing the upper limit value of the power consumption from being exceeded (hereinafter referred to as “reduction target value”). Furthermore, in addition to the reduction target value, the operation condition information includes information that distributes the amount of power consumed by each facility of the load facility 10 in order to achieve the reduction target value, and the operation that achieves the reduction target value. It may include time information representing the time at which the load facility 10 is operated with the parameters reflected.

  For example, in the present embodiment, it is assumed that the upper limit value is set to 84 kWh for the air conditioning equipment among the power consumption of the load equipment 10 installed in the corresponding space. Further, it is assumed that the power consumption amount of the air conditioning equipment 10-1 when the room temperature parameter of the air conditioning equipment 10-1 is 20 ° C. is 70 kWh from the actual data regarding the air conditioning equipment 10-1 acquired by the storage unit 110.

  Therefore, when the room temperature parameter of the air conditioning equipment 10-1 is 20 ° C. in the space, the deriving unit 120 calculates that the load equipment 10 in the space has a margin of 14 kWh from 70−84 = −14. The deriving unit 120 derives information representing the condition of the operation state of the load facility 10 such as the distribution of the calculated reduction target value and the reduction target value as the operation condition information.

  Next, the calculation unit 130 calculates an operation parameter of the load facility 10 that does not exceed the upper limit value of the power consumption amount of the load facility 10 based on the relationship information derived by the derivation unit 120.

Specifically, the calculation unit 130 calculates a parameter of the set room temperature of the air conditioner 10-1 that does not exceed the upper limit value of the power consumption of the load facility 10 based on the related information. In this example, there is a margin of -14 kWh, so it can be recognized up to the current 20% Up (70 kWh). If attention is paid only to the temperature, the room temperature is 20% Up at 20 ° C. Therefore, for example, during heating, it can be set up to 24 ° C.
From this calculation result, an upper limit value (24 ° C.) of the set room temperature, which is an operation parameter of the air conditioner 10-1 that does not exceed the upper limit value of the power consumption of the load facility 10, is calculated.
As described above, the operation parameter group for preventing the power consumption amount from exceeding the upper limit value is collectively referred to as “power consumption amount restriction parameter”.

Next, the extraction unit 140 extracts a driving parameter calculated according to the environmental state of the living space from the driving parameter set calculated by the calculation unit 130.
In addition to temperature, there are lighting equipment and other equipment in the load equipment, so in addition to these environmental information and operating condition information, the relationship between the usage state of the living space subject to energy-saving operation of the load equipment 10 and the time The operation parameters may be extracted in consideration of the information to be expressed.
Here, the term “extraction” is simply used, but it actually means that it includes a parameter data conversion process as required.

  Specifically, the scheduled execution time of the energy saving operation is from 12:00 to 13:00, the current use state of the living space (for example, 11:00) is operating on the office floor (for example, any employee is working) .), When this living space is in an operation stop (for example, lunch break) from 11:45 to 13:15, the extraction unit 140 performs air conditioning between 12:00 and 13:00 according to the above information. A combination of operation parameters of the equipment 10-1 and the lighting equipment 10-2, for example, a combination of operation parameters that does not exceed the upper limit value of the power consumption of the load equipment by maintaining the current state of the room temperature and lowering the illuminance. Can be extracted from the calculation result and the operating condition information.

Next, the display unit 150 presents operation parameters extracted by the extraction unit 140 that do not exceed the upper limit value of the power consumption of the load facility 10 to the user terminal.
In the present embodiment, display unit 150 downloads to the terminal so that the user of the corresponding living space can confirm the parameters for the desired temperature setting from the operation parameters of air conditioning equipment 10-1 extracted by extraction unit 140. . Here, an example displayed by the display unit 150 is shown in FIG.

  The power consumption reduction support apparatus 100 according to the present embodiment installs a computer program (software) in a computer (hardware) including a CPU (central processing unit), a storage device such as a memory and a hard disk, and an interface unit. Each function of the power consumption reduction support apparatus 100 described above is realized by the cooperation of various hardware resources of the computer and the computer program. Further, the computer program described above may be provided in a state stored in a computer-readable recording medium or storage device, or may be realized via an electric communication line. The power consumption reduction support device may be realized by a Web server or cloud computing instead of an ordinary computer alone.

Next, the basic operation of the power consumption reduction support apparatus 100 according to the present embodiment will be described with reference to the flowchart shown in FIG.
The storage unit 110 of the power consumption reduction support device 100 periodically acquires operation parameters related to the operation state of the air conditioning equipment 10-1 and the like, and actual values of the power consumption amounts of the facilities, respectively, and determines the operation parameters and consumption. The performance data in which the electric energy is associated is stored. At this time, the room temperature and other environmental information of the living space acquired together with the operating parameters and the actual values of the power consumption are also stored (step S101).

  When the performance data and the environment information are stored by the storage unit 110, the power consumption reduction support device 100 determines whether or not there is a power reduction request by power demand control (step S102).

If the actual value of the power consumption amount of the load facility 10 may exceed the upper limit value based on the comparison result between the predicted value of the power consumption amount and the upper limit value of the power consumption amount of the load facility 10, the power consumption reduction support The apparatus 100 determines that there is a power reduction request.
On the other hand, when there is already a power reduction request for the entire facility, the process proceeds to the following Yes process even when there is no possibility that the actual value of the current power consumption exceeds the upper limit value. This is to support more preferable temperature setting by presenting a margin.

  That is, in the case of branching to “YES” in step S <b> 102, the derivation unit 120 does not exceed the upper limit value of the power consumption amount of the load facility 10 based on the actual data and environment information stored by the storage unit 110. The operation condition information representing the operation condition and the relationship information representing the relationship between the power consumption amount of the load facility 10 and the operation parameter are derived (step S103).

When the derivation unit 120 derives the relationship information and the operation condition information, the calculation unit 130 reflects the operation parameter to be reflected in the load facility 10 that does not exceed the upper limit value of the power consumption of the load facility 10 based on the relationship information. Calculate (step S104).
When the driving parameter is calculated, the extraction unit 140 extracts the driving parameter corrected according to the environmental information acquired by the storage unit 110, the environmental state of the living space, and the driving condition information from the calculated driving parameter. (Step S105).
When an appropriate operation parameter cannot be extracted by the extraction unit 140, the user is notified that it cannot be changed. For example, the operation condition information may not be set.

When the operation parameter is extracted by the extraction unit 140, the display unit 150 downloads the extracted operation parameter to the user terminal (step S106).
When the operation parameter displayed by the display unit 150 is confirmed on the user terminal and an operation related to temperature setting is performed, the parameter reflection unit 160 reflects the corresponding operation parameter on the load facility 10 (step S107).

[2. About energy-saving operation control system]
A system for performing power demand control for a load facility including a power consumption reduction support device according to an embodiment of the present invention is a load facility operation parameter confirmed by a plurality of user terminal devices connected via a network. By executing the operation control of the load facility based on the above, the power consumption amount of the load facility is suppressed.

FIG. 3 is a diagram for explaining the configuration of the energy saving operation control system 20 including the power consumption reduction support device 200 according to the present embodiment.
As shown in FIG. 3, the energy saving operation control system 20 in the present embodiment includes a power consumption reduction support device 200 having a server function, an air conditioner controller 10a-1 that controls the operation state of the air conditioner, and the operation of the illumination facility. The load facility 10a includes at least two lighting controllers 10a-2 that control the state, and a plurality of terminal devices 30-1 to 30-n having client functions. In addition, the same code | symbol is attached | subjected to what has the same structure and function as the component of the power consumption amount reduction assistance apparatus 100 demonstrated in 1st Embodiment, and the detailed description is abbreviate | omitted.

The power consumption reduction support device 200 has a server function, and transmits and receives data to and from the terminal devices 30-1 to 30-n that are user (client) terminals.
The terminal devices 30-1 to 30-n receive the data downloaded from the power consumption reduction support device 200 and execute data processing according to the received data.
For example, when receiving the screen information of the energy saving operation confirmation screen transmitted from the power consumption reduction support device 200, the terminal devices 30-1 to 30-n display the operation parameters on the energy saving operation confirmation screen according to the received screen information. Is displayed in a state where it can be confirmed. And the information showing the temperature setting value etc. which were set by the user is transmitted to the power consumption reduction support apparatus 200.

  The display unit 250 of the power consumption reduction support device 200 generates screen information of an energy saving operation confirmation screen that displays the operation parameters extracted by the extraction unit 140 so as to be able to be confirmed, and for the terminal devices 30-1 to 30-n. Then, the data is transmitted via a transmission / reception unit 270 described later.

The set value reflecting unit 260 aggregates the operation parameters for the load facility 10a confirmed by the plurality of terminal devices 30-1 to 30-n from the confirmation result information received via the transmission / reception unit 270, which will be described later, to the load facility 10a. The operation parameter to be reflected is determined, and the determined operation parameter is transmitted to the load facility 10a via the transmission / reception unit 270.
The setting value reflection unit 260 receives the confirmation result information transmitted from the terminal device 30-n via the transmission / reception unit 270, and identifies the operation parameter corresponding to the confirmation result information.

  The transmission / reception unit 270 transmits / receives data to / from the load facility 10a and the terminal device 30-n via the network 40. The network 40 is the Internet or the like regardless of wired radio.

Next, operation | movement of the energy saving operation control system 20 in this Embodiment is demonstrated with reference to the sequence diagram shown in FIG.
The power consumption reduction support device 200 of the energy saving operation control system 20 includes an operation parameter for controlling an operation state of an air conditioning facility and a lighting facility that are operating in order to control an environment state of a living space, and a consumption of each facility. The actual value of the electric energy and the current value such as the indoor temperature, humidity, and illuminance of the living space are acquired, and the actual data and the environmental information are stored (step S201).

  When the performance data and the environmental information are stored, the power consumption reduction support apparatus 200 indicates an operation condition that represents an operation condition for the air conditioning facility that does not exceed the upper limit value of the power consumption based on the stored performance data and the environmental information. The operation parameter for deriving the information and the relationship information representing the relationship between the power consumption amount and the operation parameter to achieve the reduction target value of the power consumption amount included in the operation condition information is calculated. A parameter corresponding to the environmental information acquired from the calculation result of the operation parameter is extracted, and energy saving operation screen information for displaying the extracted parameter so as to be confirmed is generated (step S202). This parameter is a set format such as a limit value (upper / lower limit value, etc.) for temperature setting or a flag parameter indicating whether temperature setting is possible for a plurality of living spaces.

When the screen information of the energy saving operation confirmation screen is generated, the power consumption reduction support device 200 downloads the set value limit value and other information relating to the energy saving operation generated for the terminal devices 30-1 to 30-n ( Step S203).
When the terminal devices 30-1 to 30-n receive the information downloaded from the power consumption reduction support device 200, the terminal devices 30-1 to 30-n display the energy saving operation confirmation screen based on the received screen information, and the operation parameters set by the user. Is generated (step S204). When user operation information is generated corresponding to the downloaded parameter, the terminal devices 30-1 to 30-n transmit the generated setting operation information to the power consumption reduction support device 200 (step S205).

When receiving the operation information transmitted from the terminal devices 30-1 to 30-n, the power consumption reduction support device 200 determines the operation parameters to be totaled and reflected in the load facility 10a (step S206).
When the operation to be reflected in the load facility 10a is determined, the power consumption reduction support device 200 transmits information indicating the determined operation parameter to the load facility 10a (step S207).

When receiving the information indicating the operation parameter transmitted from the power consumption reduction support device 200, the load facility 10a reflects the received operation parameter in the corresponding facility and switches to the energy saving operation (step S208). Control indices such as the amount of heat source for cold water and hot water and the amount of air blown are changed.
When each facility is switched to the energy saving operation by the load facility 10a, the load facility 10a transmits the energy saving operation start information indicating that the energy saving operation is started to the power consumption reduction support device 200, and the energy saving operation start information is transmitted. The received power consumption reduction support device 200 transmits energy saving operation start information to the terminal devices 30-1 to 30-n (step S209).

[3. About user terminals]
An appearance of the terminal device 30 in the energy saving operation control system 20 is shown in FIG. FIG. 5A shows a front panel of a temperature setting device as a terminal device. Reference numeral 51 denotes a control information display unit such as an LCD, and the display unit has a touch panel. Reference numerals 52 and 53 denote temperature parameter change (increase and decrease) buttons (touch function units). FIG. 5A shows a temperature setting device in a normal state, but FIG. 5B is related to the feature of the present invention. The operation buttons include a confirmation button 54 and a cancel button 55.

Here, when the information downloaded from the power consumption reduction support apparatus 200 is received, the energy saving operation confirmation screen information is displayed in the information display area 60 based on the received information. It is confirmed or canceled by the user. That is, when the confirm button 54 is pressed, it means that the change of the temperature setting limit value of the operation parameter has been accepted. On the other hand, when the cancel button 55 is pressed, the change relating to the limit of the temperature parameter is rejected. When user operation information related to this parameter is generated, the terminal devices 30-1 to 30-n transmit the generated operation information to the power consumption reduction support device 200 as described above.

Thus, for example, since the temperature setting limit value is changed, the user can set the temperature in the range changed up and down. Note that the confirmation and cancel buttons are not essential, and may be automatically accepted depending on the type of the terminal device (temperature setting device).

In this way, as an example, the upper upper limit value can be newly changed during heating, and the power consumption reduction support apparatus 200 is regularly executed at all times. Therefore, even if the temperature parameter change is allowed temporarily, The temperature parameter may be restored again due to changing conditions. By doing so, the system can automatically cope with an environmental change without requiring the administrator to change the upper limit parameter one by one.
In addition, although the example at the time of heating is taken and the upper limit and the upper limit of the temperature parameter are described, at the time of cooling, the parameter can be interpreted as a lower limit and a lower limit.

Next, contrary to the direction of power margin, the case of power tightness will be described. If the command from the power consumption reduction support apparatus 200 predicts that energy saving cannot be achieved with the initial temperature parameter (upper limit), the power consumption reduction support apparatus 200 must lower the upper limit value of the temperature parameter from the initial value. It is not preferable for the user who is a resident to lower the setting. Rather, it is preferable not to operate the temperature setting. Then, the operation (Eco mode) is executed by changing the temperature around the set temperature value at a certain period such as 1 / f fluctuation. In addition, as a building, it may be desirable to perform the specified air conditioning operation first in the early morning for energy conservation. In that case, the user terminal may not be allowed to set temperature at all, and may be operated automatically for a certain period. is there.

At this time, since the energy saving operation specified by the system is performed, the user should not be allowed to set the temperature, and it is not necessary to display the actual room temperature. Rather, they are trying to make them aware of power saving by knowing that they are in energy-saving operation. For this reason, as shown in FIG. 5C, the button display relating to the temperature setting is erased (cannot be touched as a matter of course), and the display of the set temperature is not shown (hyphen display in the figure). Instead, an “Eco” icon may be displayed. In this way, you can feel the Eco mode.

[4. Example]
In the energy saving operation control system of the present invention, an example of temperature setting operation at the user terminal when the limit value of the temperature setting value is changed during heating operation will be described with reference to FIG.

In FIG. 6, the horizontal axis represents time, and the vertical axis represents the temperature setting value of the air-conditioned space, and the initial upper limit value is 20 ° C. and the upper upper limit value is 24 ° C.
Up to time point a on the time axis, the upper limit of the temperature setting is 20 ° C. as time region # 1.
Within this time region # 1, the set value can be changed below 20 ° C. Even if an attempt is made to exceed 20 ° C. in the figure, it is rejected as error X. This may be rejected in the user terminal, or may be sent to and received from the power consumption reduction support device 200 for inspection.

Subsequently, at time point a, it is assumed that there is a margin in power consumption, and for example, a temperature setting increase of 20% is allowed. Therefore, a new limit value (upper upper limit value) is given and the temperature is raised to 24 ° C. In this time region # 2, a message to that effect is displayed on the user terminal, and after the user confirms, the temperature set value can be increased in the range up to 24 ° C.

Next, at time point b, since the amount of power consumption increases and the marginal energy is tight, the limit value is lowered to the initial upper limit value of 20 ° C. In this time region # 3, the temperature is forcibly lowered to 20 ° C. The user confirms the display to that effect, and the upper limit of the temperature setting is 20 ° C.

Here, it is assumed that a predetermined Eco mode operation time c has come. In the subsequent time region # 4, the user cannot perform any temperature setting action at the terminal. Look at the Eco display and follow automatic driving.

It can be used for a power management system that efficiently manages power consumption in facilities such as office buildings, commercial buildings, and factories. In particular, the power management system can be used for an energy saving operation control system that executes power demand control for achieving a target value of power consumption.
