  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing an example of the configuration of a power management system 100 according to an embodiment of the present invention. As shown in FIG. 1, the power management system 100 is connected to a power management server 10, a store terminal 21, electrical devices 21 a to 21 f connected to the store terminal 21, a delivery center terminal 22, and a delivery center terminal 22. Electrical equipment (not shown) and a power supplier management server 50. In FIG. 1, only the store terminal 21 installed in the store A, the electric devices 21a to 21f connected to the store terminal 21, and the delivery center terminal 22 installed in the delivery center A are disclosed. It is good also as a structure containing the electric equipment connected to the terminal (a shop terminal and a delivery center terminal) each installed in 1 or 2 or more stores of this, or a delivery center, and the terminal. Moreover, although the electric equipment 21a-21f is illustrated in FIG. 1, what kind of thing may be sufficient if it is an apparatus which receives electric power supply and operate | moves. Hereinafter, the store terminal 21 will be described as an example.

  The power management server 10, the store terminal 21, and the power supplier management server 50 are each connected to a communication network 30 such as a LAN or the Internet. In addition, the electrical devices 21a to 21f are connected to the store terminal 21 via a communication network 40 such as a LAN or a wireless LAN. The groups 1 and 2 for classifying the electric devices 21a to 21f will be described in detail later.

  The power management server 10 is managed by a system administrator of the system 100 and is configured by an information processing apparatus such as a WWW server. Further, the store terminal 21 is managed by the store A and is configured by an information processing device such as a personal computer.

  The power management server 10 executes various processes for stopping power supply to the electrical equipment installed in each store when a predetermined condition is satisfied. The power management server 10 also includes a power management master DB 11 that stores a power management master described later, a power usage information DB 12 that stores power usage information described later, and a power supply ratio information DB 13 that stores power supply ratio information described later. And. The power management master DB 11 or the like may be inside or outside the power management server 10.

  FIG. 2 is an explanatory diagram illustrating an example of a power management master. As shown in FIG. 2, in the power management master, electric device information in which an ID (electric device ID) of a controllable electric device installed in each store is associated with a name of the electric device is registered. Has been. In addition, as shown in FIG. 2, the power management master is set with electrical equipment information of electrical equipment installed in each store for each store, and has a plurality of stop priority levels (in this example, 1 to 3) Electric device information of an electric device to be stopped for power supply is set. In this example, the power management master includes an electric device (this example) that is not subject to power supply by a specific power supplier (in this example, PPS operator Y) in the power usage information described later. , It is assumed that the electric device to be supplied by the electric power company X is set.

  An electrical device that does not interfere with store sales even if power supply is stopped is associated with a higher stop priority. In this example, it is assumed that the higher the numerical value, the lower the stop priority (that is, the harder it is to be stopped). An electrical device that does not interfere with store sales even if the power supply is stopped is associated with the highest stop priority “1”. In addition, an electrical device that has a problem that the store operation is hindered when the power supply is stopped but that can be continued is associated with a middle stop priority “2”. Then, an electrical device that causes a problem that is impossible to continue the store operation when the power supply is stopped is associated with the lowest stop priority “3”. The degree of stop priority associated with each electrical device is determined in advance by a system administrator or the like, and the power management master is set according to this determination.

  In this example, the stop priority is set to three levels, but may be two levels or four or more levels. Moreover, in FIG. 2, the stop priority with which each electric equipment is matched is an example, and may be matched with another stop priority.

  Here, the “stop priority” is the supply power of the entire target area (area managed by the power management server 10) (for example, the supply power indicated from the supply side such as an electric power company. Supply power from other power suppliers due to a decrease in the power supply ratio from a specific power supplier (hereinafter referred to as “specific power supply ratio”). This indicates the priority level for stopping the power supply when the supply ratio needs to be adjusted by reducing the power supply. In this example, the power management server 10 is a target for stopping power supply to an electrical device with a low stop priority as the specific supply power ratio decreases, and stops as the specific supply power ratio is closer to a predetermined ratio. Only high-priority electrical devices are subject to power supply interruption.

  FIG. 3 is an explanatory diagram illustrating an example of power usage information. The used power information is information related to the used power of the electrical equipment under the management of the power management server 10. In this example, as illustrated in FIG. 3, the power usage information includes a power supplier name, a reference power ratio, a power supply target, and an actual total power usage.

  Here, the “reference power ratio” indicates a reference for the ratio of the amount of power supplied from a plurality of power suppliers. In other words, in this example, the system administrator S is based on “receiving power supply at a rate of 95% from the power company X and 5% from the PPS operator Y”.

  The “power supply target” indicates which power supplier from which the electric equipment under the management of the system administrator S receives the power supply to operate. The power supply target and the power supplier may be associated with each other as long as the power management server 10 can arbitrarily instruct to stop power supply. For example, a power supplier is associated with each electric device. It is good also as a structure which the electric power supplier is matched for every facility or area. In this example, in the facility (store A or distribution center A), the electrical equipment subject to power supply by the power company X is “group 1”, and the electrical power supply target by the PPS operator Y is “group 2”. The case where it is classified will be described. Further, in this example, a store or a distribution center in which both an electrical device classified as “Group 1” and an electrical device classified as “Group 2” are installed is exemplified. It is also possible to include a store or a distribution center in which only one of the electrical equipment classified into “group” and the electrical equipment classified into “group 2” is installed.

  The “actual total power used” indicates the amount of power used by the electrical equipment under the management of the system administrator S. Note that the actual power consumption may include past total power used in addition to the current total power used, and future expected total power calculated according to a predetermined rule. Although not shown, in this example, the power usage information includes the usage status (information on whether the power is on) of each electrical device.

  FIG. 4 is an explanatory diagram illustrating an example of supply power ratio information. The supplied power ratio information is information indicating a ratio of supplied power by a plurality of power suppliers based on information acquired from the power supplier management server 50 by the power management server 10. In this example, as shown in FIG. 4, the supplied power ratio information includes the actual results on the day (maximum power per hour) and the supplied power (power scheduled to be supplied. ), Expected power supply, and power supply percentage.

  The power supplier management server 50 is a server device that manages a power supplier, and includes an information processing device such as a WWW server. Specifically, the power requester management server 50 is operated by a plurality of power suppliers that supply power to an electrical device under the management of the power management server 10 (that is, under the management of the system administrator S). It has a function of acquiring various types of information from the managed electric power company management server 60 and the PPS operator management servers 71 and 72 and executing processing to be provided to the power management server 10. The administrator of the power supplier management server 50 may be managed by the power supplier himself / herself or may be managed by a third party who is not involved in power supply.

  Next, the operation of the power management system 100 of this example will be described.

  FIG. 5 is a flowchart illustrating an example of power management processing in the power management system 100 of the present example. Here, in accordance with the operation of the administrator X managing the power management server 10, the power management server 10 instructs the electrical terminal to forcibly stop the power supply to the store terminal 21 ( That is, here, it is assumed that only information related to the store A is registered in the power management master, and the case where the power supply to the electrical device is urgently stopped by an instruction from the store terminal 21 will be described as an example. It should be noted that explanations may be omitted except for processing particularly related to the present invention.

  In this example, it is assumed that the power management process is always executed while the power management server 10 is in operation.

  In the power management process, first, the power management server 10 determines whether or not the supplied power ratio information has been acquired (step S101). If it is determined that the supply power ratio information has not been acquired (N in step S101), the power management server 10 proceeds to the process in step S104 described later.

  On the other hand, for example, when it is determined that the supply power ratio information has been acquired from the power supplier management server 50 (Y in step S101), the power management server 10 derives an expected supply power ratio from the acquired supply power ratio information (step S102). ). In this example, the power management server 10 stores the acquired supply power ratio information in the supply power ratio information DB 13, and extracts the expected supply power ratio after the current time from the stored supply power ratio information (see FIG. 4). .)

  When the predicted power supply ratio is derived, the power management server 10 determines a predetermined power supply ratio from a specific power supplier (hereinafter referred to as “specific power supply ratio”) out of the calculated predicted power supply ratio. A time zone in which the percentage of the above is reduced (hereinafter referred to as “necessary adjustment time zone”) is specified (step S103). In this example, the power management server 10 identifies time periods (12 o'clock to 13 o'clock and 13 o'clock to 14 o'clock, see FIG. 4) in which the proportion of power supplied from the PPS operator Y is less than 5%. To do.

  When the adjustment time zone is specified, the power management server 10 specifies the current time by a known method, and whether the current time is a predetermined time before the specified adjustment time zone (for example, 5 minutes before). Is determined (step S104). If it is determined that the predetermined time before the specified adjustment time zone has not been reached (N in step S104), the power management server 10 proceeds to the process in step S101.

  On the other hand, if it is determined that the adjustment time zone has been reached because it is a predetermined time before the specified adjustment time zone (Y in step S104), the power management server 10 stops based on the degree of decrease in the specific supply power ratio. A process (power supply stop target device specifying process) for specifying an electrical device that stops power supply in accordance with the priority (hereinafter referred to as “power supply stop target device” as appropriate) is executed (step S200).

  FIG. 6 is a flowchart illustrating an example of the power supply stop target device identification process. In the power supply stop target device identification process, the power management server 10 first identifies the degree of decrease in the specific supply power ratio in the adjustment time zone (that is, the specific supply power ratio is less than the predetermined ratio, the decrease level). (Step S201).

  When the reduction level is specified, the power management server 10 specifies the magnitude of the power indicated by the reduction level based on the supplied power ratio information (step S202). Specifically, the power management server 10 specifies the magnitude of the electric power indicated by the ratio based on the actual performance on the day (see FIG. 4) in the adjustment time zone required.

  Next, the power management server 10 specifies the stop priority corresponding to the specified power level (step S203). It is assumed that the power level and the stop priority are associated in advance in the power supply master. In addition, it is good also as a structure which the electric power management server 10 specifies the electric equipment according to the electric power which a fall level shows with reference to the electric power used of each of several electric equipment.

  When the stop priority is specified, the power management server 10 refers to the power management master, specifies the power supply stop target device according to the specified stop priority (step S204), and performs the process of step S105 of the power management process. (See FIG. 5).

  When the power supply stop target device is specified, the power management server 10 assigns the electric device ID of the electric device whose power supply is to be stopped to the store terminal 21 connected to the electric device whose power supply is to be stopped. A compulsory power supply stop instruction command for instructing to perform an instruction to forcibly stop power supply to the electric device indicated by the presented electric device ID is transmitted (step S105).

  When the store terminal 21 receives the forced power supply stop instruction command, the store terminal 21 outputs a power supply stop signal for instructing the power supply stop (power switch off) to each of the electrical equipments indicated by the presented electrical equipment IDs. Transmit (step S106).

  Upon receipt of the power supply stop signal, each electrical device transmits a power supply stop completion notification indicating that the power supply is stopped by executing a power supply stop process to the store terminal 21, and then Stop processing (processing to turn off the power switch) is executed.

  When the store terminal 21 receives the power supply stop completion notification from all the electric devices (step S107), the power supply stop completion for reporting that the power supply to all the corresponding electric devices has been stopped is completed. The report is transmitted to the power management server 10 (step S108). Note that if a power supply stop completion notification is not transmitted from some of the electric devices even after waiting for a certain period of time, the store terminal 21 indicates the electric devices that have completed the stop of the power supply. A power supply stop completion report including the ID may be transmitted.

  When the power management server 10 receives the power supply stop completion report, the power management server 10 creates a power supply stop completion status display screen for notifying the electric device that has been stopped to supply power, and displays the generated power supply stop completion status display. The screen is displayed on its own display device (step S109), and the process proceeds to step S101. The power supply stop completion status displayed on the power supply stop completion status display screen is updated each time a power supply stop completion report is received, for example, when receiving a power supply stop completion report from a plurality of store terminals.

  FIG. 7 is an explanatory diagram illustrating an example of a power supply stop completion status display screen. As shown in FIG. 7, on the power supply stop completion status display screen, a display area 101 for displaying the power supply stop completion status, a display area 101 for displaying the total amount of power reduced by the power supply stop, and a power supply stop An end button 103 that is pressed when closing the completion status display screen is provided.

  The administrator X grasps the power supply stop completion status by viewing the display area 101 of the power supply stop completion status display screen, and grasps the total amount of power reduced by viewing the display area 101.

  As described above, the power management server 10 instructs the electrical terminal to forcibly stop the power supply to the store terminal 21, and supplies power to the electrical device according to the instruction of the store terminal 21. An emergency stop process is executed.

  As described above, in the above-described embodiment, the power management server 10 that manages the power supply of the electrical equipment that operates by the supplied power has a plurality of predetermined stop priority levels and stop priority levels for each stage. A plurality of information based on information acquired from the power management master DB 11 storing the power management master in which the electrical equipment information indicating the electrical equipment associated with each time is set, and the power supplier management server 50 managing the power supplier Supply power ratio information DB13 for storing supply power ratio information indicating the ratio of power supplied by the power suppliers (for example, the power company X and the PPS operator Y), and the supply stored in the supply power ratio information DB13 In the power supply ratio indicated by the power ratio information, the power supply ratio from a specific power supplier (for example, PPS operator Y) determined in advance. A specific supply power ratio reduction time zone (for example, an adjustment time zone that requires adjustment; see step S103) that is a time zone in which the specific supply power rate decreases by a predetermined rate (eg, 5%) is specified (see step S103). With reference to the power management master, an electrical device that stops power supply is specified according to the stop priority based on the degree of decrease in the specified supply power ratio in the specified time zone (power supply stop target device: see step S204). , A power supply stop command (forced power supply) for instructing to stop power supply to a specific electrical device indicating the specified electrical device when a predetermined time before the specified time zone is reached (for example, 5 minutes before) Since the stop instruction command (see step S105) is transmitted via the communication network 30, each power supply is received when receiving power supply from a plurality of power suppliers. It is possible to control the amount of power supplied from the supplier.

  In other words, the power management server 10 refers to a power management master in which a plurality of predetermined stop priority levels and electrical device information indicating the electrical devices associated with the stop priority levels of each step are set. The specific supply power rate decrease time zone indicated by the supply power rate information based on the information acquired from the power supplier management server is specified, and the stop is based on the specified supply power rate decrease time period in the specified specific supply power rate reduction time zone The power supply stop target device is specified according to the priority, and the power supply to the specific electric device indicating the specified electric device is stopped when a predetermined time before reaching the specified specific supply power ratio reduction time zone is reached. Since the power supply stop command to be commanded is transmitted via the communication network 30, the specific supplier power ratio is the place in the actual power supply ratio. It is possible to control the rate of to avoid as much as possible reduced. Therefore, for example, it is possible to control the electric power price as much as possible by performing control so that the electric power purchased and supplied from the market becomes a certain ratio or more. In addition, for example, when the usage price of power supplied by a specific power supplier is lower than the usage price of power supplied by another power supplier, the degree of dependence on the power supplied from high-cost power suppliers Can be reduced. In addition, it becomes possible to propose a reduction in supply capacity for high-priced power suppliers, and as a result, a reduction in electricity usage charges can be expected. In addition, by controlling the power supply, the power supply amount for each time zone can be controlled.

  In the above-described embodiment, the power management server 10 acquires supply power ratio information from the power supplier management server 50 (see Y in step S101) and stores (registers) it in the supply power ratio information DB 13. Therefore, it becomes possible to handle highly reliable information.

  Although not particularly mentioned in the above-described embodiment, the power management server 10 generates supply power ratio information based on information acquired from the power supplier management server 50 (for example, based on a predetermined calculation formula). The generated power supply ratio information may be stored (registered) in the power supply ratio information DB 13. With such a configuration, it is not necessary to acquire all of the power supply information from the power supplier management server 50, and communication addition can be reduced.

  In the above-described embodiment, the power management server 10 stores power usage information, which is information indicating which power supplier is the target of power supply among a plurality of power suppliers. And the power management master is set with electrical equipment information indicating electrical equipment that is the target of power supply by a power supplier other than the specific power supplier (for example, the power company X). The electric device that stops the power supply from the electric devices that are the targets of power supply by the power supplier other than the specific power supplier is specified (power supply stop target device: see step S204). Therefore, the ratio of the power supplied from a specific power supplier is reduced by reducing the power supplied from another power supplier without changing the power supplied from the specific power supplier. It becomes possible to prevent.

  Further, in the above-described embodiment, the power management server 10 derives an expected supply power ratio for which a future supply power ratio is predicted based on the supply power ratio provision information stored in the supply power ratio information DB 13 (step S102), in the derived expected supply power ratio, a specific supply power ratio decrease time zone (for example, adjustment time zone required) is specified (see step S103). It becomes possible to secure the time necessary for adjusting the supply ratio before the ratio of the supplied power decreases to a predetermined ratio.

  In the above-described embodiment, the power management server 10 issues a power supply stop command (forced power supply stop instruction command: refer to step S105) to the electrical device management terminal (for example, the store terminal 21) that manages the electrical device. And the electric equipment management terminal is configured to instruct the specific electric equipment to stop power supply (see step S106) via the communication network 40 in accordance with the power supply stop instruction. The power supply stop command can be transmitted, and the processing load on the power management server 10 can be reduced.

  Further, in the above-described embodiment, the power management server 10 receives the power supply stop signal (see step S106) and indicates that the power supply from the electrical device that executes the power supply stop process is stopped. A power supply stop completion report for reporting that the stop of the power supply of the electrical equipment is completed from the electrical equipment management terminal (for example, the shop terminal 21) that has received the power supply stop completion notice (see step S107). S108) is received, and in response to receiving the power supply stop completion report, it is configured to notify the electric device that has finished stopping the power supply (see step S109). It is possible to recognize that the power supply has stopped.

  In the above-described embodiment, in the power management master, the electrical device information is terminal identification information (for example, a store) that can identify an electrical device management terminal (for example, the store terminal 21) that manages the electrical device indicated by the electrical device information. Name or store ID), it is possible to easily identify the terminal that manages the electrical device for which power supply is to be stopped, and to perform processing quickly. become.

  In the embodiment described above, in the power management master, the highest stop priority among the plurality of stages is associated with the electric device information indicating the electric device that does not interfere with the power supply, and the power supply is performed. The electric device information indicating the electric device is associated with the lower stop priority among the plurality of stages, and the power management server 10 has a specific supply power ratio as the electric device with a greater degree of trouble that occurs when stopped. The lower stop priority is specified as the degree of decrease is larger (see step S202), and the electrical device associated with the stop priority higher than the specified stop priority is specified (see step S203). It is possible to select an electrical device that appropriately stops power supply in accordance with the degree of decrease in the ratio of power supplied from the power supplier. Therefore, it is possible to prevent a situation causing trouble in the facility as much as possible, and it is possible to keep an electric device having a higher importance as much as possible.

Here, when the specified specific power supply ratio is not 5% or more which is the reference power ratio of the PPS operator Y (see FIG. 3), if it is determined that it is a predetermined ratio or more (Y in step S302), power management The server 10 proceeds to the process of step S105 in the power management process.

  On the other hand, if it is determined that the specified specific supply power ratio is not equal to or greater than the predetermined ratio (N in step S302), the power management server 10 refers to the used power information and supplies power to an electrical device that satisfies a predetermined power supply start condition. Is identified (hereinafter referred to as “power supply start target device”) (step S303) (see FIG. 8). In this example, the power management server 10 refers to the used power information, and uses the power used by the specific power supplier for the magnitude of the used power or the usage of the electric device in advance. It is assumed that the power supply start target device is specified in accordance with the criteria determined based on the criteria. For example, in the power master, the stop priority is associated with the electric device that starts power supply, and the power management server 10 refers to the power master to identify the power supply start target device. Also good.

  When the power supply start target device is specified, the power management server 10 proceeds to the process of step S105 in the power management process. However, although not shown, in this case, the power management server 10 starts power supply to the store terminal 21 connected to the electrical device whose power supply is stopped, in addition to the forced power supply stop instruction command, in step S105. The electric device ID of the target device is presented, and a forced power supply start instruction command for instructing to start power supply to the electric device indicated by the presented electric device ID is transmitted. Further, when the store terminal 21 receives the forced power supply start instruction command, the power supply stop cancellation signal for instructing the power supply (power switch on) to each electric device indicated by the presented electric device ID. Send. In addition, when each electric device receives the power supply start signal, it transmits a power supply start completion notification indicating that the power supply has been started by executing a power supply start process to the store terminal 21, and then Start processing (processing to turn on the power switch) is executed. And the store terminal 21 will receive the electric power supply start completion report for reporting that it started completing the electric power supply of all applicable electric equipment, if the electric power supply start completion notification is received from all of each electric equipment. Transmit to the power management server 10. In addition, even if it waits for a fixed period, when the notification of completion of power supply start is not transmitted from some of the electrical devices, the store terminal 21 indicates each of the electrical devices for which power supply has been started. A power supply start completion report including the ID may be transmitted. When the power management server 10 receives the power supply start completion report, the power management server 10 creates a power supply start completion status display screen for notifying an electric device that has been started to start power supply, and completes the power supply start completed. The status display screen is displayed on the display device provided in itself. At this time, the power management server 10 may be configured to display the power supply start completion status display screen and the power supply stop completion status display screen (see FIG. 7) in a switchable manner. It is good also as a structure which produces | generates and displays one screen to bear.

  The administrator X grasps the power supply start completion status by browsing the power supply start completion status display screen.

  As described above, the power management server 10 refers to the used power information, specifies an electrical device that satisfies a predetermined power supply start condition as a power supply start target device, and supplies power to the specified power supply start target device. A configuration in which a power supply start command (forced power supply start instruction command) for instructing the start of power supply is transmitted via the communication network 30 to increase the number of power supply targets from a specific power supplier. The degree of dependence on each of the plurality of power suppliers can be adjusted without stopping the power supply to the electrical equipment.

  In addition, as described above, the power management server 10 specifies the specific supply power ratio when the power supply to the specific electrical device (for example, the power supply stop target device) is stopped (for example, the PPS operator Y's An expected supply power ratio is calculated), and it is determined whether or not the specified specific supply power ratio is equal to or greater than a predetermined ratio (for example, the reference power ratio indicated by the used power information is equal to or greater than 5%). In response to determining that the ratio is not equal to or greater than the predetermined ratio, an electric device that satisfies a predetermined power supply start condition is specified as a power supply start target device (see step S303), and the predetermined power supply start condition is specified power By adopting a configuration including being a power supply target by a supplier (for example, PPS operator Y), by increasing only the power supplied from a specific power supplier, a plurality of It is possible to adjust the dependence on the respective power supplier.

  In the above example, the power management server 10 is configured to issue an instruction to stop (or start) the power supply to each electrical device via the store terminal 21, but the power management server 10 directly supplies power to each electrical device. It is good also as a structure which performs the instruction | indication for stopping supply (or starting).

  In the above example, the process for forcibly stopping (or starting) the power supply to the electrical equipment installed in the retail store has been described. However, the electrical equipment is not installed in the retail store, It may be an equipment using electric equipment that is equipment using a plurality of electric equipment such as a distribution center. The stop and start of power supply need not be compulsory. For example, the manager of the store terminal 21 may be prompted to stop or start power supply by voice output or the like.
