Abstract

PROBLEM TO BE SOLVED: To enable appropriate power saving including facility equipment not communicably connected to a power management apparatus.SOLUTION: When use electric power is to be reduced on the basis of a predicted power demand amount, the power management apparatus presents a list of equipment usable by a user, and generates a power saving navigation screen on which an operation of a state to be set by a user through a manual operation is input on the basis of the presented equipment, to preserve into a power saving navigation server. Also, in response to the generation of the power saving navigation screen, the power management apparatus transmits a power saving request mail that indicates a network address, in which the power saving navigation screen is preserved, to user terminal device of a user of the equipment.

Description

  The present invention relates to a power management apparatus.

There is a limit to the power that can be supplied by an electric power company. For example, in a season or a time zone in which the use of electrical appliances is concentrated, a situation can occur where demand power increases and there is no room for power supply.
Therefore, the following power management apparatus is known. In other words, when the power usage management device determines that the total power supplied from the power supply facility may exceed the total power setting value within a predetermined time, the power usage management device addresses the mail address stored in the user information database. Send a power saving email to. In addition, when it is determined that the power supplied from each power supply facility may exceed the power supply setting value corresponding to the power supply facility within a predetermined time, the power usage management device Transmits a power saving mail to a mail address of a user who has an address in a supply area where power is supplied (see, for example, Patent Document 1).

  In addition, the power supplied by the power company to the customers of the facility is also called demand. In addition, a contract in which a charge is set after an upper limit of electric power used is decided between an electric power company and a customer is called a demand contract. A consumer who has signed a demand contract with an electric power company controls the power used in the facility so as not to exceed the determined contract power. Such power control is also called demand control. In addition, BEMS (Building and Energy Management System) is used for management of facilities with demand control.

JP 2006-166617 A

  In BEMS, a power management apparatus and an equipment such as an air conditioner and a lighting are connected to be communicable. The power management apparatus controls operations such as air conditioning and lighting via this communication. However, as a matter of fact, there are many facility devices in the facility that cannot be connected to BEMS so as to be communicable, but are connected to a power strip and receive power supply. Therefore, some BEMS has a problem that it can control only the equipment connected by communication among the equipment operating in the facility.

The technique described in Patent Document 1 is intended to promote user power saving by transmitting a power saving mail. In Patent Document 1, a user who has received a power saving mail performs a proper operation by selecting a device to be saved from among devices in the home by self-judgment, and is connected to BEMS in this respect. It can be said that it indirectly controls the operation of devices that are not.
However, facilities where BEMS is equipped are larger than homes. For this reason, the number and types of equipment that are operating without being connected to the facility by the BEMS are considerable, and there are many people in the facility. Therefore, even if a mail for prompting power saving is simply transmitted to the user in such a facility, it is difficult for each user to appropriately select the power saving target equipment and perform fine power saving.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to accurately perform power saving including equipment that is not communicably connected to a power management apparatus.

  In order to solve the above-described problem, a power management apparatus as one aspect of the present invention should reduce power consumption based on a power demand prediction unit that predicts power demand and at least the predicted power demand When it is determined that the power consumption should be reduced, and a reduction necessity determination unit that determines whether or not the power consumption is to be reduced, a list of facility devices registered in association with the user is presented and presented A power-saving navigation screen generation unit that generates a power-saving navigation screen in which an operation to input a state set by a user by manual operation is performed for each piece of equipment and stores it in the power-saving navigation server, and according to the generation of the power-saving navigation screen The power saving navigation screen is saved for the user terminal device of the user registered as a user of the equipment. And an electronic mail transmitting unit that transmits the power saving request mail indicating an address on that network.

  As described above, according to the present invention, it is possible to accurately save power including facility equipment that is not communicably connected to the power management device.

[Configuration of power management system]
Hereinafter, a power management apparatus according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration example of a power management system including a power management apparatus according to an embodiment of the present invention.
The power management system shown in this figure includes a power management device 100 in a facility 1, a power saving navigation server 300, a mail server 400, and a user terminal device 500. The power management apparatus 100, the power saving navigation server 300, the mail server 400, and the user terminal apparatus 500 are connected via a network 600 so that they can communicate with each other.

In the facility 1, there are N buildings 200-1 to 200-N. Hereinafter, the buildings 200-1 to 200-N will be referred to as the building 200 unless otherwise distinguished.
In the building 200, a power distribution unit 210 and a plurality of rooms 220 are provided. The power distribution unit 210 distributes power supplied from, for example, a commercial power supply or a power storage device (not shown) supplied by an electric power company to each room 220 in the same building 200 and supplies the power to each room 220.
Each of the rooms 220 is arranged at a predetermined place on a predetermined floor in the building 200. A plurality of facility devices are provided in the room 220.

  The power management apparatus 100 is also called a BEMS (Building and Energy Management System), and manages the power used in the facility 1. In the present embodiment, a demand contract is made with an electric power company for the power usage of the facility 1. In response to this, the power management apparatus 100 executes demand control. That is, the power management apparatus 100 controls the equipment connected via the communication network in each room 220 so that the power used in the facility 1 does not exceed the contract power.

FIG. 2 shows an example of the interior of the room 220. The room 220 in this figure is provided with two types of equipment, that is, a control target device 222 and a non-control target device 223.
The control target device 222 is a facility device that can control the operation of the power management apparatus 100 by being connected to the power management apparatus 100 via a communication network.
The non-control target device 223 is a facility device that is not connected to the power management apparatus 100 via a communication network, and therefore the power management apparatus 100 cannot control its operation.
The control target device 222 and the non-control target device 223 can operate by receiving power supply from the power distribution unit 210 by connecting the connector of the power cable to the power tap 221, for example.
In this figure, two control target devices 222 and non-control target devices 223 are shown, but the numbers of control target devices 222 and non-control target devices 223 in the room 220 are not particularly limited. Also, in this figure, one power strip 221 is shown, but a plurality of power strips 221 may be provided in the room 220.

Returning to FIG.
The power saving navigation server 300 manages the power saving navigation screen generated by the power management apparatus 100 for each room (room) registered for use by the user, together with an address (URL (Uniform Resource Locator)) on the network. To save. The power saving navigation server 300 has a configuration as a web server that provides a power saving navigation screen.

  The mail server 400 delivers electronic mail. When the power management apparatus 100 determines that the power demand in the predicted facility 1 should be suppressed, the power management apparatus 100 transmits a power saving request mail requesting power saving to each user terminal device 500 as a destination. The mail server 400 transfers the power saving request mail transmitted in this way to the destination user terminal device 500.

  The user terminal device 500 is a terminal device owned by each user registered as a user of equipment in the facility 1. The user terminal device 500 has a web browser function for accessing and browsing a website on a network such as the Internet, and a function for sending and receiving electronic mail. Specifically, the user terminal device 500 is a personal computer, a smartphone, a tablet terminal, a mobile phone, or the like.

[Overview of power management]
Next, an overview of power management realized by the power management apparatus 100 will be described with reference to FIG.
The graph in FIG. 3 shows the power demand for each time period according to a predetermined time length predicted on a certain day. This predicted power demand is power predicted to be necessary for the entire facility 1, and is predicted by the power management apparatus 100 using, for example, the predicted temperature of the weather forecast.
Here, the predicted temperature indicated by the curve A1 indicates the weather forecast updated at the previous day or at the timing when this one day starts, and the predicted temperature indicated by the curve A2 is after the first day has started. The weather forecast updated at the timing when the time has passed is shown.

  As shown in FIG. 3, the power management apparatus 100 sets a predetermined threshold th for the predicted power demand. This threshold is set based on, for example, contract power contracted with an electric power company for the facility 1.

When the predicted power demand exceeds the threshold th, the power management apparatus 100 determines the power reduction amount so that the used power does not exceed the threshold th. Then, the power management apparatus 100 creates an operation plan for the control target device 222 so as to achieve the determined power reduction amount. And the power management apparatus 100 performs demand control according to this operation plan. That is, the power supply and settings of the control target device 222 are appropriately controlled via communication.
In the present embodiment, the power management apparatus 100 recognizes a level 1 when the power demand predicted based on the predicted temperature at the start timing of the previous day or one day indicated by the curve A1 exceeds the threshold th.

  Furthermore, in this figure, the predicted temperature in the middle of the day shown by the curve A2 is higher than the curve A1. For this reason, the power demand amount predicted based on the curve A2 is also higher than the power demand amount predicted based on the curve A2. In this case, the power management apparatus 100 sets the level 2 power saving mode. Level 2 has more power to be reduced than level 1, and is more urgent when performing demand control. When recognizing that it is the level 2 power saving mode, the power management apparatus 100 re-determines the reduced power, changes the operation plan so as to obtain the re-determined reduced power, and executes demand control.

  In the demand control, since the operation of the control target device 222 in each room 220 is controlled via communication as described with reference to FIG. 2, the operation of the non-control target device 223 cannot be controlled. For this reason, even if demand control is performed, it is inevitable that many non-control target devices 223 are operating in the room 220. This means that demand control cannot be performed effectively only by controlling only the control target device 222. This problem becomes more prominent as the facility 1 becomes larger and the number of non-control target devices 223 increases.

  Therefore, the power management system of the present embodiment can indirectly control the operations of these non-control target devices 223 during demand control as described below. Thereby, it becomes possible to reduce power more effectively in conjunction with demand control for the control target device 222.

The power management apparatus 100 acquires the weather forecast for the next day via the network 600 at a predetermined time on the previous day, for example, and based on the predicted temperature indicated by the acquired weather forecast, the power demand amount in the facility 1 on the next day Predict.
Next, the power management apparatus 100 determines that the level 1 demand control should be executed if the predicted power demand is equal to or greater than the threshold th. At this time, the power management apparatus 100 transmits the first level power saving request mail corresponding to the level 1 with the user terminal apparatus 500 of the user registered as the user of the facility 1 as the destination. The first power saving request mail corresponding to the level 1 has, for example, a content indicating that the power demand amount is expected to increase tomorrow and that power saving is requested to be cooperated.
A user who has received the first power saving request mail corresponding to level 1 can have a precaution to save power in advance tomorrow.

  Thereafter, at the timing corresponding to the start of the day, the power management apparatus 100 acquires the latest weather forecast at the present time and predicts the power demand amount again. The weather forecast acquired at this time is more reliable than the weather forecast of the previous day, for example. That is, the power management apparatus 100 can predict the power demand amount with higher reliability by re-predicting the power demand amount at the timing corresponding to the start of the day.

For example, when the predicted temperature is lower than the previous day's forecast and the power demand predicted at the timing corresponding to the start of the day does not exceed the threshold th, the power management apparatus 100 sets the level set on the previous day. Cancel 1 power saving mode. Thereby, demand control is not performed on the day.
On the other hand, when the power demand predicted at the timing corresponding to the start of the day exceeds the threshold th, the power management apparatus 100 maintains the level 1 power saving mode determined on the previous day.
In addition, the power management apparatus 100 generates a power saving navigation screen and stores it in the power saving navigation server 300. The power saving navigation screen presents a list of facility devices (non-control target devices 223) installed in a room (room) registered for use by the user and manually displays each non-control target device 223 that is presented. It is a screen on which an operation for inputting a state set by the user is performed.
Next, the power management apparatus 100 transmits a second power saving request mail corresponding to level 1 with the user terminal apparatus 500 of the user registered as a user of the facility 1 as a destination.

FIG. 4A shows an example of content when the user terminal device 500 that has received the second power saving request mail corresponding to level 1 displays the text. As shown in this figure, in the second power saving request mail corresponding to level 1, first, the text of the content requesting to save power today, and the URL of the power saving navigation screen generated corresponding to this user A link to is displayed.
Therefore, the user performs an operation of clicking the link of the URL displayed in the second power saving request mail corresponding to level 1. In response to this operation, the web browser of the user terminal device 500 accesses the power saving navigation screen indicated by the clicked URL and displays the image. An example of the power saving navigation screen 700 displayed in this way is shown in FIG.

The power saving navigation screen 700 shown in FIG. 5A is described in a markup language such as HTML, for example. As shown in the figure, the equipment list area 710 and the equipment listed in the equipment list area 710 are shown. A corresponding operation area 720 is displayed for each.
The device list area 710 is an area where non-control target devices 223 registered as users who view the list are users. The operation area 720 is an operation in which, for example, “already”, “turn on (on)”, or “turn off (off)” is selected for the state set in the non-control target device 223 when the user performs power saving on the current day. This is the area to be performed.
Note that the operation area 720 in FIG. 5A has display contents in the initial state. That is, in the initial state, the button 721 is arranged in the “attach” area in all the operation areas 720.

The user operates the operation area 720 for each non-control target device 223 listed in the device list area 710.
That is, if the power is already turned off for the non-control target device 223, for example, the user performs a touch operation on the “already” area and arranges the button 721 in the “already” area.
If it is necessary to turn on the power of the non-control target device 223, the user operates the button 721 to be arranged in the “ON” area.
In addition, the power of the non-control target device 223 is normally on, but if the device is to be turned off in response to a request for power saving this time, the user operates the button 721 to be placed in the “extinguish” area. To do.

  FIG. 7B shows an example of the content of the power saving navigation screen 700 after the above operation is performed for each list of all non-control target devices 223. The arrangement of the buttons 721 in the operation area 720 for each non-control target device 223 is appropriately changed depending on the operation on the operation area 720 so far.

  Then, when the operation on the operation area 720 for each non-control target device 223 is finished as described above, the user performs an operation on the determination button 730. As a result, device state information indicating a state set by the user manually for each non-control target device 223 in accordance with the arrangement of the button 721 for “already”, “turn on”, or “delete” for each non-control target device 223 Is transmitted from the user terminal device 500 to the power saving navigation server 300. The power saving navigation server 300 stores the received device status information in association with the user ID of the user registered as the owner of the user terminal device 500 that is the transmission source.

  In response to the transmission of the device status information as described above, for example, as shown in FIG. 4B, an e-mail notifying that the current device status information has been normally received is transmitted. May be. The transmission of this e-mail may be performed by the power saving navigation server 300 or may be performed by the power management apparatus 100 in response to a normal reception notification of device state information from the power saving navigation server 300. Further, instead of sending an e-mail, for example, the web server function of the power saving navigation server 300 causes the user terminal device 500 to display a web image notifying that the current device status information has been normally received. May be.

  The power management apparatus 100 acquires the device state information stored as described above from the power saving navigation server 300. Next, the power management apparatus 100 estimates the power reduction amount according to the non-control target device 223 whose power is switched off in the facility 1 using the device state information. And the power management apparatus 100 calculates | requires the electric power which should be reduced by control by the control object apparatus 222 side based on the estimated electric power reduction amount, and produces an operation plan so that the calculated | required electric power may be reduced. Then, the power management apparatus 100 executes demand control according to this operation plan on the day.

While executing demand control according to the operation plan on the day, the power management apparatus 100 uses, for example, the predicted temperature of the latest weather forecast at the present time, and predicts the power demand after about one hour from the current time. When the predicted power demand exceeds the threshold th while the level 1 demand control is being executed, the level 2 power saving mode is set as described with reference to FIG. .
As the setting of the level 2 power saving mode, the power management apparatus 100 performs the following operation. That is, the power management apparatus 100 generates the power saving navigation screen 700 corresponding to the level 2 power saving mode. In this level 2 power saving mode, the power management apparatus 100 generates a power saving navigation screen 700 showing the previous operation result in the level 1 power saving mode. That is, in correspondence with the example of FIG. 7, the power management apparatus 100 generates the power saving navigation screen 700 having the same contents as in FIG.
Next, the power management apparatus 100 transmits a power saving request mail corresponding to level 2 with the user terminal apparatus 500 of the user registered as a user of the facility 1 as a destination. This power saving request mail corresponding to level 2 is, for example, to a text indicating that the power demand is expected to increase recently, and to request cooperation with power saving, and to the URL of the power saving navigation screen 700 corresponding to this user The link is shown.

  Note that the power saving navigation screen 700 in the initial state saved corresponding to level 1 may be updated to the contents reflecting the operation result and saved in the same URL in the power saving navigation server 300. In this case, the power management apparatus 100 does not need to generate the power saving navigation screen 700, and only needs to transmit a power saving request mail corresponding to level 2.

The user who has received the level 2 power saving request mail and displayed it on the user terminal device 500 clicks the URL link in the power saving request mail. Thereby, the browser of the user terminal device 500 displays the power saving navigation screen 700 having the contents shown in FIG. 7B, for example, by accessing the clicked URL. In the device list shown in FIG. 7B, the user selects a button that can be turned off from among the buttons 721 arranged in the “turn on” area, and clicks the button in the “turn off” area. An operation of arranging 721 is performed. Thereafter, the user performs an operation on the determination button 730. In response to this, device status information is transmitted from the user terminal device 500 to the power saving navigation server 300, and the power saving navigation server 300 stores the received device status information in association with the user ID.
And the power management apparatus 100 acquires the apparatus state information memorize | stored as mentioned above from the power-saving navigation server 300, and also estimates the electric power reduced by the non-control object apparatus 223 by which a power supply is switched off. Then, the power management apparatus 100 also uses this estimation result to create an operation plan for level 2 demand control as described above. And the power management apparatus 100 performs demand control according to this operation plan after the present time, for example.

Thus, in this embodiment, a power saving request mail is transmitted to the user. Then, the power saving navigation screen 700 is displayed on the user terminal device 500 by accessing the URL to which the link is pasted in the power saving request mail. In the power saving navigation screen 700, for example, non-control target devices 223 that are authorized to be operated by the user in a room (room) registered for use by the user are listed. Therefore, the user can accurately select the non-control target device 223 that may be turned off while confirming what the listed non-control target device 223 is.
Further, in the power management apparatus 100, the power reduced by switching off the power supply of the non-control target device 223 from the operation status of the non-control target device 223 indicated by the device status information that is the operation result on the power saving navigation screen 700 is obtained. Can be estimated. Then, the power management apparatus 100 determines power (control target power) to be reduced on the control target device 222 side using the estimated power reduction amount, and operates for demand control based on the control target power. You can create a plan. Thereby, in this embodiment, power saving including the non-control object apparatus 223 which is not connected so as to be communicable with the power management apparatus 100 can be accurately performed.

[Configuration of power management device]
FIG. 6 shows a configuration example of the power management apparatus 100. The power management apparatus 100 shown in this figure includes a power demand amount prediction unit 110, a reduction necessity determination unit 120, a demand control unit 130, a power saving navigation screen generation unit 140, an e-mail transmission unit 150, and a storage unit 160.

The power demand amount prediction unit 110 predicts a power demand amount that is power required with the use of equipment in a facility.
For this purpose, the power demand amount prediction unit 110 acquires necessary information such as predicted temperature in the weather forecast via the network, and predicts the power demand amount using the acquired information. The power demand amount prediction unit 110 predicts the power demand amount on the next day and the power demand amount on the day, and predicts the power demand amount after a certain time from the current day.

The reduction necessity determination unit 120 determines whether or not the power consumption should be reduced based on the power demand amount predicted by the power demand amount prediction unit 110.
Further, the reduction necessity determination unit 120 measures the amount of power demand on the day and determines whether or not the power consumption should be reduced based on the actually measured value.
Specifically, the reduction necessity determination unit 120 is used depending on whether the predicted power demand for the next day, the predicted power demand for one day on the day, or the measured value of the power demand is equal to or greater than the threshold th. Determine if power should be reduced.

  Further, the reduction necessity determination unit 120 determines that the level 1 when the predicted value of the power demand on the next day is equal to or greater than the threshold th and when the predicted value of the power demand for the day on the current day is equal to or greater than the threshold th. Set the power saving mode. Further, the reduction necessity determination unit 120 further measures the power demand amount on the day in a state where the demand control as the level 1 power saving mode is being executed, and this measured value (actually measured value) is equal to or greater than the threshold th. It is determined whether or not. When the measured value of the power demand is equal to or greater than the threshold th, the possibility that the used power will exceed the contracted power in the latest period is considerably increased. Therefore, the reduction necessity determination unit 120 in this case sets the level 2 power saving mode.

The demand control unit 130 operates the facility device (the control target device 222) so that the power consumption in the facility 1 is equal to or less than a certain value in response to the reduction necessity determination unit 120 determining that the power usage should be reduced. Execute demand control to control
The demand control unit 130 acquires the operating status of the non-control target device 223 indicated by the power saving navigation screen 700 from the power saving navigation server 300 when performing demand control. The demand control unit 130 estimates the power that can be reduced by the non-control target device 223 that is switched off based on the acquired operating status. The demand control unit 130 calculates the power to be reduced by the control target device 222 using the estimation result, and creates an operation plan using the calculation result. And the demand control part 130 performs demand control according to the produced operation plan. That is, the demand control unit 130 controls the operation of the control target device 222 through communication.

The power saving navigation screen generation unit 140 is a room in which the user uses the power saving navigation screen 700 corresponding to the level 1 in response to the predicted value of the daily power demand on the day being set to the threshold th or more. (Room) Created separately and stored in the power saving navigation server 300.
In addition, the power saving navigation screen generation unit 140 uses the level 2 power saving navigation screen 700 indicating the previous operation result as the user uses the measured value of the power demand amount on the day that is equal to or greater than the threshold th. It is generated for each registered room (room) and stored in the power saving navigation server 300. As described above, in the power saving navigation server 300, when the power saving navigation screen 700 is updated and stored according to the contents after the operation, the power saving navigation screen generation unit 140 displays the power saving navigation screen 700 corresponding to level 2. There is no need to generate. In addition, the power saving navigation screen generation unit 140 appropriately uses information stored in the storage unit 160 when generating the power saving navigation screen 700.

  In response to the generation of the power saving navigation screen 700, the e-mail transmission unit 150 applies the power saving navigation screen in the power saving navigation server 300 to the user terminal device 500 of the user registered as the user of the non-control target device. An electronic mail (power saving request mail) indicating an address (URL) of 700 is transmitted. In addition, when it is determined that the actual measurement value of power demand on the day is equal to or greater than a certain value, that is, when it is recognized that it is level 2, the e-mail transmission unit 150 transmits a power saving request mail corresponding to level 2. To do. That is, the e-mail transmission unit 150 transmits an e-mail indicating an address on the network where the power saving navigation screen 700 showing the state of the non-control target device 223 set by the previous operation is stored. In addition, the e-mail transmission unit 150 appropriately uses information stored in the storage unit 160 when generating the power saving request mail.

  The storage unit 160 stores information necessary for the power saving navigation screen generation unit 140 to generate the power saving navigation screen 700 and information necessary for the e-mail transmission unit 150 to generate an e-mail. Specifically, the storage unit 160 stores a user database 161, a device database 162, a location database 163, a room management database 164, and a power saving pack database 165.

[Example of database contents]

[Example of processing procedure]
The flowchart in FIG. 12 illustrates an example of a processing procedure executed by the power management apparatus 100. First, as described above, the power demand amount prediction unit 110 predicts the next day's power demand amount in the facility 1 using, for example, the next day weather forecast information acquired via the network (step S101).

  The reduction necessity determination unit 120 determines whether or not the power consumption should be reduced based on the power demand on the next day predicted in step S101 (step S102). That is, the reduction necessity determination unit 120 in this case determines that the power to be used should be reduced if the predicted power demand on the next day is equal to or greater than the threshold th, and accordingly sets the level 1 power saving mode. . On the other hand, if it is less than the threshold th, the reduction necessity determination unit 120 determines that it is not necessary to reduce the power used.

  When it is determined that the power consumption should be reduced and the level 1 power saving mode is set accordingly (step S102—YES), the e-mail transmission unit 150 sends the first power saving request mail corresponding to level 1 to the user. Generate for each. Then, the e-mail transmission unit 150 transmits the generated first level 1 power saving request mail corresponding to the level 1 to the user terminal device 500 of each user via the mail server 400 (step S103). If it is determined that the value is less than the threshold th (step S102—NO), the e-mail transmission unit 150 proceeds to step S111 described later.

  In addition, the reduction necessity determination unit 120 obtains the latest weather forecast information after a predetermined time after the prediction in step S101, and uses the weather forecast information for the power of the day. The demand amount is predicted (step S104). The reduction necessity determination unit 120 determines whether or not the power consumption should be reduced based on the power demand predicted in step S104 (step S105). At this time, the reduction necessity determination unit 120 determines whether or not the power consumption should be reduced depending on whether or not the predicted power demand is equal to or greater than the threshold th.

When it is determined that it is not necessary to reduce the power consumption (NO in step S105), the e-mail transmission unit 150 cancels the power saving request for notifying that the current power saving request notified by e-mail transmission the other day is canceled. Mail is transmitted to each user (step S115), and the process proceeds to step S111. In this case, when the first power saving request mail corresponding to level 1 is transmitted in step S103 in advance, for example, the e-mail transmission unit 150 sends an e-mail notifying that the power saving request has been canceled to the user. You may make it transmit to the terminal device 500.
On the other hand, when it is determined that the power consumption should be reduced (step S105—YES), the power saving navigation screen generation unit 140 executes the following processing. That is, the power saving navigation screen generation unit 140 generates a power saving navigation screen 700 corresponding to level 1 for each user and stores it in the power saving navigation server 300 so as to be managed together with the address (URL) (step S106).

  Further, in response to the generation of the power saving navigation screen 700, the e-mail transmission unit 150 generates a second power saving request mail corresponding to the level 1 having the contents illustrated in FIG. It transmits to the user's user terminal device 500 (step S107).

  As described with reference to FIG. 5, when the second power saving request mail corresponding to level 1 is received by the user terminal device 500, the user accesses his / her own power saving navigation screen 700 in the power saving navigation server 300. And a user performs operation with respect to a power-saving navigation screen from the user terminal device 500, and performs operation which inputs a power-on / off state for every non-control object apparatus 223 listed. Then, this operation result is transmitted from the user terminal device 500 to the power saving navigation server 300 as device state information.

The demand control unit 130 receives the device state information transferred from the power saving navigation server 300 (step S108).
Next, the demand control unit 130 creates an operation plan corresponding to level 1 (step S109). For this purpose, for example, the demand control unit 130 estimates the power reduced by the non-control target device 223 whose power is switched off by manual operation using the received device state information. Further, the demand control unit 130 uses this estimated power to create an operation plan as described above.

And the demand control part 130 performs the demand control in the day according to the driving | operation plan produced as mentioned above (step S110).
Moreover, the reduction necessity determination part 120 measures the electric power demand amount on the day, performing the state monitoring in the facility 1 (step S111). In addition, the actual measurement value of the power demand amount in the facility 1 can be obtained by, for example, adding up the used power notified from the power distribution unit 210 for each building 200.

  The reduction necessity determination unit 120 determines whether or not the power consumption should be reduced based on the measured value (actual value) of the power demand actually measured in step S111 (step S112). At this time, the reduction necessity determination unit 120 determines whether or not the power consumption should be reduced based on whether or not the actual measurement value of the power demand is equal to or greater than the threshold th.

  Here, when it is determined that it is not necessary to reduce the power consumption (step S112—NO), the process returns to step S111 to measure the power demand and whether the power demand is greater than or equal to the threshold th. The determination as to whether or not to reduce the power consumption based on the determination (step S112) is repeated.

On the other hand, when it determines with it being more than the threshold th (step S112 -YES), the reduction necessity determination part 120 sets the power saving mode of level 2. FIG.
In response to this, the power saving navigation screen generation unit 140 generates a power saving navigation screen 700 corresponding to level 2 and stores it in the power saving navigation server 300 (step S113). Further, the e-mail transmission unit 150 generates a power saving request mail corresponding to level 2 and transmits it to each user terminal device 500 (step S114). As described above, when the previous operation result for the power saving navigation screen 700 is stored in the power saving navigation server 300, step S113 can be omitted.

FIG. 13 shows an example of a processing procedure for generating a power saving navigation screen and generating and transmitting a power saving request mail as steps S106 and S107 of FIG.
First, the power saving navigation screen generation unit 140 determines a target value (power saving level) of power to be reduced by turning off the power of the non-control target device 223 according to the setting of the level 1 power saving mode (step S100). S201). At this time, the power saving navigation screen generation unit 140 determines the power saving level based on, for example, the predicted power demand and the power reduced by demand control on the control target device 222.

  The power saving navigation screen generation unit 140 searches the power saving pack database 165 stored in the storage unit 160 for a record storing the determined power saving level as an attribute, and the non-control target device stored in the operation target device list of this record The device ID of 223 is extracted (step S202).

  Next, the power saving navigation screen generation unit 140 searches the device database 162 stored in the storage unit 160 for a record that stores the device ID extracted in step S202 as an attribute. And equipment ID and a power-saving management level are extracted from the searched record (step S203).

  Next, the power saving navigation screen generation unit 140 searches the room management database 164 stored in the storage unit 160 for a record storing the location ID extracted in, for example, step S203, and the users included in the user list of this record An identifier is extracted (step S204).

  By searching the database so far, the power saving navigation screen generation unit 140 specifies the non-control target device 223 to be operated by each user in association with the installed location, building, room, and the like. Based on this result, the power saving navigation screen generation unit 140 creates a list of non-control target devices 223 to be operated for each room (room) registered for use by the user (step S205). Then, the power saving navigation screen generation unit 140 generates the power saving navigation screen 700 reflecting the device list for each room (room) registered for use by the user, specifies the URL, and saves it in the power saving navigation server 300. (Step S206).

  Further, the e-mail transmission unit 150 searches for a record including a user ID corresponding to each power saving navigation screen 700 created from the user database 161. Then, the mail address and name for each user are extracted from the retrieved record (step S207). Next, the e-mail transmission unit 150 generates a power saving request mail in which the extracted mail address is a destination, and the extracted name is inserted in the text together with, for example, the standard text, and transmits the generated power saving request mail (step S208). ).

  The sequence diagram of FIG. 14 is executed in the power management system in response to generation of the power saving navigation screen 700 by the power saving navigation screen generation unit 140 and storage in the power saving navigation server 300 and transmission of the power saving request mail by the e-mail transmission unit 150. An example procedure is shown.

  In the power management apparatus 100, the power saving navigation screen generation unit 140 generates the power saving navigation screen 700 and stores it in the power saving navigation server 300 (step S301), and the e-mail transmission unit 150 transmits a power saving request mail (step S302).

  The mail server 400 transfers the power saving request mail received from the power management apparatus 100 to the user terminal device 500 (step S303).

  The web browser of the user terminal device 500 that has received the power saving request mail accesses the power saving navigation screen 700 indicated by the URL pasted as a link to the power saving request mail (step S304). As a result, the web browser of the user terminal device 500 displays the accessed power saving navigation screen 700. As described with reference to FIG. 5, the user operates the displayed power saving navigation screen 700. In response to the completion of this operation, the web browser of the user terminal device 500 transmits device state information indicating the operation result to the power saving navigation server 300. (Step S305)

  The power saving navigation server 300 transfers the received device state information to the power management apparatus 100 (step S306). The power management apparatus 100 uses the transferred device state information to create an operation plan for demand control, for example, as described above.
