[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-207635 Summary of the Invention [Problem to be solved by the invention]

[0004] During demand response (DR) control, the target value of demand control is lowered, so no control is performed for the first 5 minutes of the 30-minute demand control interval. In other words, control is performed at the next control timing, and no control is performed for the first 6 minutes. This narrows the range of power reduction in response to the demand response command. Furthermore, if demand control or demand response control is performed and the same control is performed on all equipment, the risk of damage to the equipment increases. An object of the present invention is to provide a monitoring device, a monitoring method, and a program that can reduce the risk of damage to equipment. [Means for solving the problem]

[0014] Next, a monitoring device, a monitoring method, and a program according to the present embodiment will be described with reference to the drawings. The embodiment described below is merely an example, and the embodiments to which the present invention is applied are not limited to the following embodiments. Note that in all drawings used to explain the embodiments, the same reference numerals are used for components having the same functions, and repeated explanations will be omitted. Furthermore, in this application, "based on XX" means "based on at least XX," and includes cases where it is based on other elements in addition to XX. Furthermore, "based on XX" is not limited to cases where XX is used directly, but also includes cases where it is based on XX that has been calculated or processed. "XX" is any element (for example, any information).

[0015] (Embodiment) (High voltage power receiving monitoring device) FIG. 1 is a diagram illustrating an example of a high-voltage power receiving monitoring device 1 according to this embodiment. The high-voltage power receiving monitoring device 1 is an example of a monitoring device. The high-voltage power receiving monitoring device 1 includes a high-voltage smart meter 2, a communication IF 11 that communicates with the high-voltage smart meter 2 via a LAN cable L1, a target value setting unit 12 that sets / changes a target demand power (hereinafter also referred to as a "target value") for determining the power usage status, a memory 13 that stores measured demand power data and the set target value, a display unit 14 with an LCD display, an output unit 16 that outputs a demand control signal (hereinafter referred to as a "control signal") to specific loads (controlled loads) 4A to 4C, a control unit 17 that controls the calculation of the demand power data and the setting of the target value, and controls each unit of the high-voltage power receiving monitoring device 1, and a communication IF 18 that communicates with an external device 3, which is an external operating means, via an internet network N. Here, an example of the controlled load is equipment such as an air conditioner.

[0016] The high-voltage smart meter 2 incorporates a demand power meter (not shown) as one of the functions of a conventional high-voltage watt-hour meter, and in addition to the conventional functions, it also has a communication unit (not shown) that returns demand power data in response to a request from the high-voltage power receiving monitoring device 1. Here, the demand power meter is a device for calculating the basic electricity charge for consumers, and calculates demand power data (30-minute demand power data) every 30 minutes (demand period) and stores the maximum value of that data for one month. Based on this data, the demand power meter uses the larger of the maximum value of the demand power data for the past 11 months or the demand power data for the current calculation month (maximum demand power data) as the reference data for calculating the basic charge. The high-voltage smart meter 2 may be installed inside or outside a cubicle that houses the power receiving equipment.

[0017] In this embodiment, communication between the high-voltage smart meter 2 and the high-voltage power reception monitoring device 1 is performed via a LAN cable L1. However, communication between the high-voltage smart meter 2 and the high-voltage power reception monitoring device 1 may be performed via power line communication (PLC) communication, or wireless communication using Wi-SUN (Wireless Smart Utility Network). In either case, data is obtained via route B communication. An example of the external device 3 is a personal computer on which predetermined application software is installed. The external device 3 sets / changes the target value by operating an operation unit. The target value set / changed by the external device 3 is displayed on the display unit 14 of the high-voltage power receiving monitoring device 1.

[0018] The target value setting unit 12 sets the target demand power and the target value for demand response (DR) control every 30 minutes (demand cycle). Furthermore, the target value setting unit 12 has an operation unit, such as a numeric keypad, for setting various numerical values. The target value setting unit 12 may also have a simple change button (not shown) for increasing or decreasing the already set target value by a certain amount with a simple operation. The memory 13 stores 11 months of demand power data transmitted by the high-voltage smart meter 2, demand power data which is the demand power for each demand cycle of the current month, set target values ​​(target demand power for each demand cycle, target value for demand response control), etc.

[0019] The control unit 17 functions as a derivation unit 17-1, a determination unit 17-2, a creation unit 17-3, and a DR control unit 17-4. The derivation unit 17-1 acquires demand power data from the high-voltage smart meter 2 via the communication IF 11, and derives an estimated value of demand power for each demand cycle at regular time intervals based on the acquired demand power data. Furthermore, when an interruption of DR control occurs, the derivation unit 17-1 derives the control amount of the controlled load that is being controlled among the controlled loads 4A to 4C.

[0020] The determination unit 17-2 obtains the target value from the target value setting unit 12 and obtains the estimated value of the demand power for each demand cycle from the derivation unit 17-1. The determination unit 17-2 determines whether the estimated value of the demand power for each demand cycle exceeds the target value. Furthermore, when an interruption of DR control occurs, the determination unit 17-2 acquires the target value of DR control from the target value setting unit 12 and acquires the control amount of the controlled load from the derivation unit 17-1. The determination unit 17-2 determines whether the acquired control amount of the controlled load exceeds the target value of DR control.

[0021] The creation unit 17-3 creates a control signal for controlling at least one of the controlled loads 4A to 4C based on the determination result by the determination unit 17-2 of whether or not the estimated value of demand power exceeds the target value for each demand cycle. The creation unit 17-3 outputs the created control signal to the output unit 16. The output unit 16 outputs the control signal output by the creation unit 17-3. For example, based on a preset order, the creation unit 17-3 creates a control signal for controlling at least one of the controlled loads 4A to 4C in a rotational manner. When an interruption of DR control occurs, the creation unit 17-3 creates a control signal for controlling the control load that is being controlled. The creation unit 17-3 outputs the created control signal to the output unit 16. The output unit 16 outputs the control signal output by the creation unit 17-3.

[0022] Next, a description will be given of the operation of the high-voltage power reception monitoring device 1. Fig. 2 is a flowchart showing an example of the operation of the high-voltage power reception monitoring device 1 according to this embodiment. A main flow of the high-voltage power reception monitoring device 1 will be described with reference to Fig. 2. (Step S1-1) The target value setting unit 12 sets a target value for demand monitoring and control. Here, demand monitoring and control includes not only monitoring but also controlling the load. (Step S2-1) The derivation unit 17-1 monitors the demand. Specifically, the derivation unit 17-1 acquires current demand power data from the high-voltage smart meter 2 via the communication IF11.

[0023] (Step S3-1) The derivation unit 17-1 derives an estimated value of demand power for each demand cycle based on the acquired current demand power data. The determination unit 17-2 acquires a target value from the target value setting unit 12 and acquires an estimated value of demand power for each demand cycle from the derivation unit 17-1. The determination unit 17-2 determines whether the estimated value of demand power acquired for each demand cycle exceeds the target value. If the determination unit 17-2 determines that the estimated value of demand power does not exceed the target value, the process returns to step S2-1.

[0024] (Step S4-1) When the determination unit 17-2 determines that the estimated value of demand power exceeds the target value, the creation unit 17-3 creates a control signal for controlling the controlled loads 4A to 4C to be OFF. The output unit 16 outputs the control signal created by the creation unit 17-3 to the controlled loads 4A to 4C. The controlled loads 4A to 4C are controlled to be OFF by the control signal output by the output unit 16.

[0025] (Step S5-1) The derivation unit 17-1 determines whether a predetermined first time, such as one minute, has elapsed since the controlled loads 4A to 4C were controlled to be turned off. If the derivation unit 17-1 determines that the predetermined first time has not elapsed, the process returns to step S4-1, and the controlled loads 4A to 4C continue to be controlled to be turned off.

[0026] (Step S6-1) When the derivation unit 17-1 determines that the predetermined time has elapsed, it derives an estimated value of demand power for each demand cycle based on the acquired current demand power data. The determination unit 17-2 acquires the target value from the target value setting unit 12, and acquires the estimated value of demand power for each demand cycle from the derivation unit 17-1. The determination unit 17-2 determines whether the estimated value of demand power acquired for each demand cycle is less than the target value. When the determination unit 17-2 determines that the estimated value of demand power is not less than the target value, the process returns to step S4-1, and the controlled loads 4A to 4C continue to be controlled to be off.

[0027] (Step S7-1) If the determination unit 17-2 determines that the estimated value of the demand power is less than the target value, the derivation unit 17-1 determines whether a predetermined second time, such as six minutes, has elapsed since the controlled loads 4A to 4C were controlled to be turned off. If the derivation unit 17-1 determines that the predetermined second time has not elapsed, the process returns to step S4-1, and the controlled loads 4A to 4C continue to be controlled to be turned off.

[0028] (Step S8-1) When the derivation unit 17-1 determines that the predetermined second time has elapsed, the creation unit 17-3 creates a control signal for controlling the controlled loads 4A to 4C to be ON. The output unit 16 outputs the control signal created by the creation unit 17-3 to the controlled loads 4A to 4C. The controlled loads 4A to 4C are controlled to be ON by the control signal output by the output unit 16. Then, the process returns to step S2-1.

[0029] 2, the case where the high-voltage power receiving monitoring device 1 turns on or off all of the controlled loads 4A, 4B, and 4C is described, but this is not limited to this example. For example, the on / off control may be performed in a rotational manner in the order of 4A and 4B, 4B and 4C, and 4C and 4A. In other words, a number of controlled loads less than the number of controlled loads may be controlled in a rotational manner. Here, either or both of the number and combination of controlled loads to be controlled in a rotational manner can be set as appropriate.

[0030] Fig. 3 is a flowchart showing an example of the operation of the high-voltage power receiving monitoring device 1 according to this embodiment. A case where a DR control interrupt occurs in the high-voltage power receiving monitoring device 1 will be described with reference to Fig. 3. Here, as an example, a case where candidates for load control are controlled in rotation in the order of controlled load 4A, controlled load 4B, controlled load 4C, and controlled load 4A will be described. (Step S1-2) The target value setting unit 12 sets a target value for the DR control. (Step S2-2) The DR control unit 17-4 initially sets the control load 4A as a control candidate, and thereafter, normal control is performed until a DR command interrupt occurs.

[0031] The explanation will continue with the case where a DR command interrupt occurs. (Step S3-2) The communication IF 18 receives the DR command. The DR control unit 17-4 acquires the interrupt DR command from the communication IF 18. (Step S4-2) The DR control unit 17-4 sets the control load 4B as a control candidate based on the acquired interrupt DR command.

[0032] (Step S5-2) The derivation unit 17-1 derives the control amount of the control load 4B. The determination unit 17-2 acquires the target value of the DR control from the target value setting unit 12 and acquires the control amount of the control load 4B from the derivation unit 17-1. The determination unit 17-2 determines whether the control amount of the control load 4B exceeds the target value of the DR control. (Step S6-2) If the determination unit 17-2 determines that the control amount of the controlled load 4B does not exceed the target value of the DR control, the DR control unit 17-4 sets the controlled load 4C as a control candidate.

[0033] (Step S7-2) The derivation unit 17-1 derives the control amount of the control load 4C. The determination unit 17-2 acquires the target value of the DR control from the target value setting unit 12 and acquires the control amount of the control load 4C from the derivation unit 17-1. The determination unit 17-2 determines whether the control amount of the control load 4C exceeds the target value of the DR control. (Step S8-2) If the determination unit 17-2 determines that the control amount of the control load 4C does not exceed the target value of the DR control, the derivation unit 17-1 determines whether a predetermined third time, such as six minutes, has elapsed since the demand-off control. If the derivation unit 17-1 determines that the predetermined third time has not elapsed, the process returns to step S7-2.

[0034] (Step S9-2) If the derivation unit 17-1 determines in step S8-2 that the predetermined third time has elapsed, the DR control unit 17-4 sets the controlled load 4A as a control candidate. (Step S10-2) If the determination unit 17-2 determines in step S5-2 that the control amount of the controlled load 4B exceeds the target value of DR control, if the determination unit 17-2 determines in step S7-2 that the control amount of the controlled load 4C exceeds the target value of DR control, or if the DR control unit 17-4 sets the controlled load 4A as a control candidate in step S9-2, the DR control unit 17-4 determines whether a DR end command has been issued. If a DR end command has not been issued, the process returns to step S5-2.

[0035] (Step S11-2) When a DR end command is issued, the DR control unit 17-4 turns off the DR load control and proceeds to the main flow. 3, the case where the high-voltage power receiving monitoring device 1 controls the controlled load 4A, the controlled load 4B, and the controlled load 4C in rotation in this order has been described, but this is not limited to this example. For example, the controlled loads may be controlled in rotation in the order of 4A and 4B, 4B and 4C, and 4C and 4A, and the combination of controlled loads to be controlled in rotation can be set as appropriate.

[0036] In the above-described embodiment, as an example, the case where the high-voltage power receiving monitoring device 1 controls three controlled loads, controlled load 4A to controlled load 4C, has been described, but this is not limiting. For example, the high-voltage power receiving monitoring device 1 may be configured to control k controlled loads (k is an integer greater than 1). In this case, the high-voltage power receiving monitoring device 1 may rotate among the k controlled loads to control the controlled loads that are less than k.

[0037] According to the high-voltage power receiving monitoring device 1 of the embodiment, the high-voltage power receiving monitoring device 1 includes a communication IF11 as a communication unit that receives demand power data from the high-voltage smart meter, a derivation unit 17-1 that derives an estimated value of demand power for each demand cycle based on the demand power data, a judgment unit 17-2 that judges whether the estimated value of demand power for each demand cycle derived by the derivation unit 17-1 exceeds the target demand power, a creation unit 17-3 that creates a control signal to control control loads less than k out of k (k is an integer greater than 1) control loads based on the judgment result by the judgment unit 17-2, and an output unit 16 that outputs the control signal created by the creation unit 17-3.

[0038] With this configuration, the high-voltage power receiving monitoring device 1 can control less than k of the k controlled loads based on whether the estimated value of demand power for each demand cycle exceeds the target demand power. This not only enables continuous control from the start of control, but also reduces the risk of damage to the controlled loads compared to when the same control is performed on all controlled loads.

[0039] The high voltage power receiving monitoring device 1 further includes a demand-response control unit 17-4 that controls less than k control loads in a rotational manner among the k control loads when an interruption in demand-response control occurs. By configuring it in this way, the high-voltage power receiving monitoring device 1 can control less than k of the k control loads in a rotational manner when an interruption occurs in demand-response control. Because control can be performed continuously from the start of control, the range of power amounts that can be controlled during demand-response control can be expanded. In addition, the risk of damage to the control loads can be reduced compared to when the same control is performed on all control loads. Furthermore, demand monitoring control and demand-response control can be performed using the same circuit configuration. Here, demand monitoring control includes not only monitoring but also controlling the loads.

[0040] In the high-voltage power receiving monitoring device 1, the judgment unit 17-2 judges whether the control amount of the control load less than k exceeds the target value of the demand-response control, and if the judgment unit 17-2 determines that the control amount of the control load less than k does not exceed the target value of the demand-response control, the demand-response control unit 17-4 transitions to control of the next control load less than k based on a rotation system. With this configuration, the high-voltage power receiving monitoring device 1 can control the controlled loads less than k out of the k controlled loads in a rotational manner based on whether the control amount of the controlled loads less than k exceeds the target value for demand-response control. Because control can be performed continuously from the start of control, the range of power amounts that can be controlled during demand-response control can be expanded. Furthermore, the risk of damage to the controlled loads can be reduced compared to when the same control is performed on all controlled loads.

[0041] In the high voltage power receiving monitoring device 1, the number of the next controlled loads is different from the number of the previous controlled loads. By configuring in this manner, when the high-voltage power receiving monitoring device 1 controls less than k control loads in a rotational system out of k control loads, it can increase the number of combinations of control loads to be controlled in a rotational system compared to when the same number of control loads are controlled in a rotational system.

[0042] In the high-voltage power receiving monitoring device 1, the judgment unit 17-2 judges whether the control amount of the control load less than k exceeds the target value of the demand-response control, and the demand-response control unit 17-4 judges whether a demand-response termination command has been issued when the judgment unit 17-2 judges that the control amount of the control load less than k exceeds the target value of the demand-response control. By configuring in this manner, the high-voltage power receiving monitoring device 1 can determine whether a demand response termination command has been issued when it is determined that the control amount of a control load less than k exceeds the target value of demand response control, and can therefore return to the main flow when a demand response termination command has been issued.

[0043] Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and design modifications and the like are also included within the scope of the present invention. For example, a computer program for realizing the functions of each of the above-described devices may be recorded on a computer-readable recording medium, and the computer program recorded on this recording medium may be read and executed by a computer system. Note that the "computer system" referred to here may also include hardware such as an OS and peripheral devices.

[0044] Additionally, "computer-readable recording media" refers to writable non-volatile memory such as flexible disks, optical magnetic disks, ROMs, and flash memories, portable media such as DVDs (Digital Versatile Discs), and storage devices such as hard disks built into computer systems. Furthermore, "computer-readable recording media" also includes devices that retain a program for a certain period of time, such as volatile memory (e.g., DRAM (Dynamic Random Access Memory)) within computer systems that act as servers or clients when a computer program is transmitted via a network such as the Internet or a communication line such as a telephone line.

[0045] The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by transmission waves in the transmission medium. Here, the "transmission medium" that transmits the program refers to a medium that has the function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. The program may also be for realizing part of the above-mentioned functions. Furthermore, it may be a so-called differential file (differential program) that can realize the above-mentioned functions in combination with a program already recorded in the computer system.
