Description

Control device, control method, and computer program

Embodiments described herein relate generally to a control device, a control method, and a computer program.

A technology called VPP (Virtual Power Plant) has been put into practical use, which integrates multiple small-scale private power generation facilities and power demand control by software, and controls power supply and demand as if it were a single power plant. .
Conventionally, the supply and demand balance of power is maintained by demand response (hereinafter referred to as “DR”) in VPP. However, a heat source facility such as an air conditioner consumes higher power at the time of startup than at normal times. Therefore, when a heat source facility such as an air conditioner is targeted for DR, a peak may occur in power demand at the time of restart after the DR is implemented. Thus, the phenomenon in which a peak occurs at the time of restart after DR execution is called a rebound effect. The peak of power demand generated by the rebound effect is called rebound peak. Due to the occurrence of this rebound peak, the VPP may not be able to supply sufficient power for the power demand at the time of restart after DR execution.

The problem to be solved by the present invention is to provide a control device, a control method, and a computer program capable of suppressing an increase in power consumption per unit time due to a rebound effect.

The control device of the embodiment has a control unit. The control unit outputs control information for releasing the restriction on the operation of the management target based on a time determined for each management target with respect to a plurality of management targets whose operation is limited to suppress power consumption.

(First embodiment)
FIG. 1 is a system configuration diagram illustrating a system configuration of a VPP system 1 according to the first embodiment.
The VPP system 1 in FIG. 1 is a VPP system that controls power supply and demand in a target facility. In the example of FIG. 1, buildings 2-1 and 2-2 are facilities to be controlled. The building 2-1 has facilities 3-1-1 and 3-1-2. The building 2-2 has facilities 3-2-1 and 3-2-2. The facilities 3-1-1, 3-1-2, 3-2-1 and 3-2-2 are facilities that operate by electricity. VPP-NOC4 (control device) is a network operating center of VPP. The VPP-NOC 4 monitors the power consumption in the facility to which power is supplied, and instructs the load controller 5 or BAS (Building Automation System) 6 to execute a demand response (DR). The load controller 5 controls power supply to a building that does not have a BAS. The load controller 5 controls the execution of DR for the facilities 3-1-1 and 3-1-2 based on an instruction from the VPP-NOC 4. The BAS 6 is installed in a control target building and controls power supply to the target building. The BAS 6 controls the execution of DR for the facilities 3-2-1 and 3-2-2 based on an instruction from the VPP-NOC 4.

In the following description, the buildings 2-1 and 2-2 are described as the building 2 unless otherwise distinguished for the sake of simplicity. Similarly, the equipment 3-1-1 to 3-1-2 are referred to as equipment 3-1. Similarly, facilities 3-2-1 to 3-2-2 are referred to as facility 3-2. Similarly, facilities 3-1 and 3-2 are referred to as facility 3.

FIG. 2 is a diagram illustrating a specific example of the rebound effect in the first embodiment.
In FIG. 2, the horizontal axis represents time, and the vertical axis represents power consumption in the building 2 to be controlled. Reference numeral 10 in FIG. 2 represents a baseline set in the building 2 to be controlled. The baseline is electric power that becomes a reference value when measuring a load (electric power) reduction amount of a consumer in a negawatt transaction. In negawatt trading, the customer's load reduction is marketed as much as the power generated by the power plant. Since the amount of power generation is the amount of power generated itself, it is easy to measure. On the other hand, the load reduction amount of the consumer may have been originally consumed, but cannot be measured because it is the amount of power that was not actually consumed. Therefore, in the negawatt transaction, the amount of power that may have been consumed originally needs to be set in advance. This preset amount of power is the baseline.
That is, when the actual power consumption falls below the baseline power, the difference in the power becomes the load reduction amount of the consumer.

The above baseline needs to be determined in consideration of the power supply / demand balance. Further, the daily power consumption depends on external conditions such as the climate and the weather of the day. Therefore, the baseline needs to be determined taking into account these environmental factors. One example of a model for formulating such a baseline is Baseline Type 1. In Baseline Type 1, a baseline is determined by adjusting the influence of external conditions on a moving average of power consumption on business days excluding holidays using a predetermined algorithm. In the present embodiment, the baseline formulation method is not limited to a specific method.

Reference numeral 11 represents the power consumption actually consumed by the equipment 3 installed in the building 2 to be controlled. DR is running during the time _{t 2} from time _{t 1} in FIG. That is, the equipment 3 which is selected to perform the DR is stopped at time t ₁ in the building 2 to be controlled. The facilities 3 which are stopped is restarted at time t _2. Therefore, power consumption is reduced in the DR running period from time t ₁ at time t _2. However, after the end of the DR, the power consumption greatly exceeds the baseline due to the restart of the equipment 3. This is the rebound effect. Specifically, the rebound effect appears in the portion indicated by reference numeral 12 in the example of FIG.

FIG. 3 is a functional block diagram showing functional configurations of the VPP-NOC 4 and the load controller 5.
First, the functional configuration of the VPP-NOC 4 will be described.
The VPP-NOC 4 includes a CPU (Central Processing Unit), a memory, an auxiliary storage device, and the like connected by a bus, and executes a DR control program. The VPP-NOC 4 functions as a device including a communication unit 41, a storage unit 42, a DR control unit 43 (control unit), a load information acquisition unit 44, and an activation information determination unit 45 (determination unit) by executing a DR control program. Note that all or part of the functions of the VPP-NOC 4 may be realized by using hardware such as an application specific integrated circuit (ASIC), a programmable logic device (PLD), and a field programmable gate array (FPGA). The DR control program may be recorded on a computer-readable recording medium. The computer-readable recording medium is, for example, a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, or a storage device such as a hard disk built in the computer system. The DR control program may be transmitted via a telecommunication line.

The communication unit 41 is configured using a communication interface such as a LAN (Local Area Network). The communication unit 41 communicates with the load controller 5.
The storage unit 42 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 42 stores an activation information table 421.

FIG. 4 is a diagram illustrating a specific example of the activation information table 421.
The activation information table 421 has an activation information record for each control target facility. The activation information record has values of control target equipment, rebound generation amount, rebound time, presence / absence of delay, and delay time. The control target equipment represents equipment that is a DR execution target. The control target equipment is selected by the VPP-NOC 4 at the time of DR execution based on the conditions such as the contents of the contract between the customer and the electric power company and the power consumption characteristics of each equipment 3 that varies depending on the climate.

The amount of rebound generated represents the power consumption at startup indicating the power consumed by the control target equipment at startup. The rebound time represents the time during which the rebound effect generated in the controlled facility continues. Specifically, the rebound time is the time from the start of the control target equipment until the power consumption converges to a level close to the steady state after the occurrence of the rebound effect. The presence or absence of the delay time is determined based on the amount of rebound generation and the rebound time, and represents whether or not to delay the restart timing of the controlled equipment. The delay time is a time indicating how much the restart timing of the controlled equipment is delayed.
Note that the amount of rebound generation may be determined based on the actual power consumption of the control target equipment in the past DR in addition to the above-described power consumption at startup. For example, a baseline for each control target facility may be determined based on the actual power consumption. In this case, the amount of rebound generation may be determined as the amount of power that exceeds the predetermined baseline of each control target facility.
Further, the rebound time may be set as the time from when the control target equipment is activated until the peak of power consumption occurs in the rebound effect, in addition to the “time when the rebound effect continues”.

Returning to the description of FIG.
The DR control unit 43 controls the execution of DR of the building 2 to be controlled. Specifically, the DR control unit 43 transmits control information for instructing the load controller 5 to execute DR via the communication unit 41. When instructing DR execution, the DR control unit 43 selects the control target equipment and notifies the load controller 5 of it. The DR control unit 43 instructs the load controller 5 to execute DR on the selected control target equipment. When the DR is completed, the DR control unit 43 instructs the load controller 5 to restart the control target equipment based on the presence / absence of delay and the delay time value in the startup information table 421.

The load information acquisition unit 44 acquires, from the load controller 5, information on power consumed by the restarted control target equipment (hereinafter referred to as “restart power information”) after DR execution. The load information acquisition unit 44 acquires the rebound generation amount and the rebound time for each control target facility based on the restart power information and the baseline. The load information acquisition unit 44 registers the acquired rebound generation amount and rebound time for each control target facility in the activation information table 421.

The activation information determination unit 45 determines a delay time indicating the timing to activate the control target equipment when the control target equipment is restarted after the DR is executed. Specifically, the activation information determination unit 45 determines a delay time for restart of each control target facility for the control target facility restarted at the timing when the DR execution period ends. The delay time is a time based on the timing when the DR execution period ends. The activation information determination unit 45 refers to the activation information table 421 and acquires the rebound generation amount and the rebound time of the controlled facility. Based on the amount of rebound generated and the rebound time of the control target equipment, the start information determining unit 45 controls each control target so that the power consumed by each control target equipment in the control target building 2 does not exceed the baseline. Determine equipment delay time. In the example of FIG. 4, no delay time is set for the facility 7. This indicates that the delay time of the facility 7 is “0”, that is, there is no delay. Therefore, the presence / absence of delay of the facility 7 is “none”, and the presence / absence of delay of the facilities 7 other than “present”.

Next, the functional configuration of the load controller 5 will be described.
The load controller 5 includes a CPU, a memory, an auxiliary storage device, and the like connected by a bus, and executes a DR execution program. The load controller 5 functions as a device including the communication unit 51 and the DR execution unit 52 by executing the DR execution program. All or some of the functions of the load controller 5 may be realized using hardware such as an ASIC, PLD, or FPGA. The DR execution program may be recorded on a computer-readable recording medium. The computer-readable recording medium is, for example, a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, or a storage device such as a hard disk built in the computer system. The DR execution program may be transmitted via a telecommunication line.

The communication unit 51 is configured using a communication interface such as a LAN. The communication unit 51 communicates with the VPP-NOC 4.
The DR execution unit 52 executes DR of the control target equipment in accordance with an instruction from the VPP-NOC4.
Further, the DR execution unit 52 restarts the control target equipment in accordance with an instruction from the VPP-NOC 4 after the DR is executed.

FIG. 5 is a flowchart showing a DR control flow of the VPP-NOC4.
First, the DR control unit 43 selects a control target facility that is a target of DR execution (step S101). The DR control unit 43 instructs the load controller 5 to execute DR on the selected control target equipment (step S102).

Next, the DR control unit 43 refers to the activation information table 421 and acquires the value of the delay time of each control target facility. The DR control unit 43 waits for the delay time acquired for each control target facility from the timing when the DR execution period ends. When the standby time expires the delay time, the DR control unit 43 instructs the load controller 5 to start the control target equipment corresponding to the delay time. (Step S103).

When the restart of each control target facility is completed, the start information determination unit 45 performs a delay time determination process (step S104), and determines the delay time of each control target facility at the time of restart after the next DR execution. .

FIG. 6 is a flowchart showing the flow of the delay time determination process in the first embodiment.
First, the load information acquisition unit 44 acquires restart power information for each control target facility from the load controller 5 (step S201). The load information acquisition unit 44 acquires the rebound generation amount and the rebound time for each control target facility based on the restart power information and the baseline. The load information acquisition unit 44 registers the acquired rebound generation amount and rebound time of each control target facility in the activation information table 421 (step S202). Next, the activation information determination unit 45 determines the delay time of each control target facility based on the rebound generation amount and the rebound time of the control target facility (step S203). The activation information determination unit 45 registers the determined delay time of each control target facility in the activation information table 421.

FIG. 7 is a diagram illustrating an operation example of the VPP system 1 according to the first embodiment.
In FIG. 7, the horizontal axis represents time, and the vertical axis represents power consumption in the building 2 to be controlled. Reference numeral 10 in FIG. 7 represents a baseline set in the building 2 to be controlled. The code | symbol 13 represents the electric power actually consumed by the installation 3 installed in the building 2 to be controlled. DR is running during the time period from _{t 4} in FIG. 7 at time _{t 3.} That is, the equipment 3 which is selected to perform the DR is stopped at time t ₃ in the building 2 to be controlled. The facilities 3 which are stopped is restarted at time t _4. Therefore, power consumption is reduced in the DR running period from time t ₃ at time t _4. Then, the controlled installation based time t ₄ to the delay time determined as a reference by being activated, rebound effect after DR execution is suppressed in the building 2 to be controlled. Reference numerals 14-1 to 14-3 represent power consumption at the start-up for each control target facility. By starting the control target equipment at different timings as shown in FIG. 7, the rebound peaks of the control target equipment are controlled so as not to overlap.

In addition, when BAS6 exists in the control object building of VPP system 1 like FIG. 1, DR may be controlled by BAS6 having the same function structure as VPP-NOC4. In this case, the BAS 6 performs a delay time determination process similar to that of the VPP-NOC 4 for the control target equipment in the building 2 where the own system is installed, and sets the delay time of each control target equipment in the restart after the DR execution. decide.

In the VPP system 1 of the first embodiment configured as described above, the delay time in restart after DR execution is determined based on the amount of rebound generated for each control target facility. After the completion of DR, each controlled object facility is restarted based on this delay time, whereby the occurrence of a rebound peak in VPP can be suppressed.

(Second Embodiment)
FIG. 8 is a system configuration diagram showing a system configuration of the VPP system 1a of the second embodiment.
The VPP system 1a shown in FIG. 8 is a VPP that controls the buildings 2-1 to 2-3. Buildings 2-1 to 2-3 are buildings to be controlled by the VPP system 1a. The VPP system 1 a is different from the VPP system 1 in that a CBEMS (registered trademark, the same applies hereinafter) (Cluster Building Energy Management System) 7 is provided instead of the load controller 5 and the BAS 6. The VPP-NOC 4 controls the CBEMS 7 and executes a demand response (DR) for each building to be controlled.

FIG. 9 is a diagram illustrating a specific example of the rebound effect in the second embodiment.
In FIG. 9, the horizontal axis represents time, and the vertical axis represents the total power consumption of all buildings to be controlled. Reference numeral 15 in FIG. 9 represents a baseline. Reference numeral 16 represents the power actually consumed in the controlled building 2. DR is running during the time period from _{t 6} from time _{t 5} in FIG. In other words, the DR execution target equipment is stopped in each building 2 selected from the control target buildings 2 to execute DR. The facilities each building 2 which has been stopped is restarted at time t _5. Therefore, power consumption is reduced in the DR running period from time t ₅ the time t _6. However, after the end of the DR, the total power consumption of each building 2 that is the DR execution target greatly exceeds the baseline. This is the rebound effect in the second embodiment. Specifically, the rebound effect appears in the portion indicated by reference numeral 17 in the example of FIG.

FIG. 10 is a functional block diagram showing a functional configuration of the CBEMS 7. As shown in FIG.
The CBEMS 7 (control device) includes a communication unit 71, a storage unit 72, a DR control unit 73 (control unit), a load information acquisition unit 74, and an activation information determination unit 75 (determination unit).

The communication unit 71 is configured using a communication interface such as a LAN. The communication unit 71 communicates with each building 2.
The storage unit 72 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 72 stores an activation information table 721.

FIG. 11 is a diagram illustrating a specific example of the activation information table 721.
The activation information table 721 has an activation information record for each control target building. The activation information record has values of a control target building, a rebound generation amount, a rebound time, a delay presence / absence, and a delay time. The control target building represents a building that is a DR execution target. The controlled building is selected at the time of DR execution based on conditions such as the contents of the contract between the customer and the electric power company and the characteristics of the power consumption of each building that varies depending on the climate.

The rebound generation amount represents the amount of power that has exceeded the baseline due to the rebound effect generated in the controlled building. The rebound time represents the time during which the rebound effect generated in the controlled building continues. The presence or absence of the delay time is determined based on the amount of rebound generated and the rebound time, and represents whether or not to delay the timing of restarting the equipment of the controlled building for each controlled building. The delay time is a time indicating how much the restart timing of the equipment of the controlled building is delayed.

Returning to the description of FIG.
The DR control unit 73 controls execution of DR of the building 2 to be controlled. The DR control unit 73 receives a DR execution instruction from the VPP-NOC 4. The DR control unit 73 selects a control target building according to the DR execution instruction. The DR control unit 73 executes DR for the selected control target building. When the execution of the DR is completed, the DR control unit 73 restarts the equipment for each controlled building based on the presence / absence of delay and the value of the delay time in the activation information table 721.

The load information acquisition unit 74 acquires information on power consumed in each controlled building after the equipment is restarted after DR execution (hereinafter referred to as “restart power information”). The load information acquisition unit 74 acquires the rebound generation amount and the rebound time for each controlled building based on the restart power information and the baseline. The rebound generation amount and rebound time acquired by the load information acquisition unit 74 are registered in the activation information table 721.

The activation information determination unit 75 determines the timing for starting the equipment of the controlled building in the restart of the equipment of the controlled building after DR execution. Specifically, the activation information determination unit 75 determines the delay time of each control target building for the control target building whose facilities are restarted at the timing when the DR execution period ends. The activation information determination unit 75 refers to the activation information table 721 and acquires the rebound generation amount and the rebound time for each controlled building. The activation information determination unit 75 determines the delay time of each control target building so that the power consumed when the equipment of the control target building is restarted does not exceed the baseline based on the rebound generation amount and the rebound time of the control target building. To decide. In the example of FIG. 11, no delay time is set for the building 7. This indicates that the delay time of the building 7 is “0”, that is, there is no delay. Therefore, the presence / absence of delay of the building 7 is “None”, and the presence / absence of delay of the building 7 other than “Yes”.

FIG. 12 is a flowchart showing the DR control flow of the CBEMS 7.
First, the DR control unit 73 determines whether or not a DR execution instruction has been issued from the VPP-NOC 4 (step S301). If it is determined that the DR execution instruction has not been issued (step S301—NO), the process returns to step S301, and the DR control unit 73 repeats the determination of whether or not the DR execution instruction has been issued. On the other hand, when it is determined that a DR execution instruction has been performed (YES in step S301), the DR control unit 73 selects a control target building in accordance with the DR execution instruction (step S302). The DR control unit 73 executes DR on the selected control target building and stops the operation of the equipment of the control target building (step S303).

Next, the DR control unit 73 refers to the activation information table 721 and acquires the delay time value of each control target building. The DR control unit 73 waits for the delay time acquired for each control target building from the timing when the DR execution period ends. When the standby time expires the delay time, the DR control unit 73 activates the equipment of the controlled building corresponding to the delay time. (Step S304).

When the restart of the facilities of each control target building is completed, the CBEMS 7 performs a delay time determination process (step S305), and determines the delay time of each control target building at the time of restart after the next DR execution.

FIG. 13 is a flowchart showing the flow of the delay time determination process in the second embodiment.
First, the load information acquisition unit 74 acquires restart power information for each control target building (step S401). The load information acquisition unit 74 acquires a rebound generation amount and a rebound time for each control target building based on the restart power information and the baseline. The load information acquisition unit 74 registers the acquired rebound generation amount and rebound time of each control target building in the activation information table 721 (step S402). Next, the activation information determination unit 75 determines the delay time of each control target building based on the rebound generation amount and rebound time of the control target building (step S403). The activation information determination unit 75 registers the determined delay time of each control target building in the activation information table 721.

FIG. 14 is a diagram illustrating an operation example of the VPP system 1a according to the second embodiment.
In FIG. 14, the horizontal axis represents time, and the vertical axis represents power consumption in the controlled building. Reference numeral 15 in FIG. 14 represents a baseline of power consumed in all controlled buildings. The code | symbol 18 represents the sum total of the power consumption actually consumed in all the control object buildings. DR is running during the time _{t 8} from FIG. 14 at time _{t 7.} That is, the equipment of the selected control target buildings to perform the DR is stopped at time t ₇ against buildings of the controlled object. The facilities of stop controlled object buildings is restarted at time t _8. Therefore, power consumption in the DR execution period of time t ₈ from the time t ₇ is lowered. Then, by the equipment is started every control target building on the basis of time t ₈ to the delay time which is determined as a reference, rebound effect after DR execution is suppressed in buildings of the controlled object. Reference numerals 19-1 to 19-3 represent power consumption at the time of activation for each control target building. The equipment of the control target building is activated at different timings as shown in FIG. 14 so that the rebound peaks of the control target buildings are not overlapped.

In the VPP system 1a of the second embodiment configured as described above, the delay time in restarting the equipment of each controlled building after DR execution is determined based on the amount of rebound generated for each controlled building. After the completion of DR, the equipment of each controlled building is restarted based on this delay time, so that the occurrence of rebound peaks in VPP can be suppressed.

Below, the modification of VPP system 1 and 1a of embodiment is demonstrated.
FIG. 15 is a diagram illustrating an operation example of the modified VPP system 1.
In FIG. 15, the horizontal axis represents time, and the vertical axis represents power consumption in the control target equipment. Reference numeral 10 in FIG. 15 represents a baseline set in the building 2 to be controlled. Reference numeral 20 represents the power actually consumed by the equipment 3 installed in the building 2 to be controlled. DR is running during the time _{t 10} from FIG. 15 at time _{t 9.} That is, the equipment 3 which is selected to perform the DR is stopped at time t ₉ in building 2 to be controlled. Then, it restarted in equipment 3 the time t ₁₀ which is stopped. Therefore, power consumption is reduced in the DR running period between the time t ₁₀ from the time t _9. Then, the controlled installation on the basis of time t ₉ to the delay time determined as a reference is activated. As illustrated in FIG. 15, the delay time of the control target facility may be determined such that the generation time of the rebound peak due to the start of the control target facility is a time zone in which the power rate is low. Similarly, in the VPP system 1a, the delay time of the control target building may be determined so that the generation time of the rebound peak due to the restart of the equipment of the control target building is a time zone in which the power rate is low.

The VPP system 1a of the embodiment may give an incentive according to the length of the delay time to the controlled building. For example, the storage unit 72 of the CBEMS 7 stores an activation information table 721a in which an incentive is set for each control target building.
FIG. 16 is a diagram illustrating a specific example of the activation information table 721a.
The activation information table 721a has an activation information record for each control target building. The activation information record has values of a control target building, a rebound generation amount, a rebound time, a delay presence / absence, a delay time, and an incentive. The controlled object building, rebound generation amount, rebound time, presence / absence of delay, and delay time are the same as those in the activation information table 721. The incentive represents the amount of incentive set according to the delay time. In the example of FIG. 16, a larger incentive value is set for a control target building having a longer delay time. The VPP system 1a can improve the motivation of a power consumer to cooperate with DR by giving an incentive according to delay time to the controlled building cooperated with DR.

The VPP system 1 may reduce the amount of rebound generated by stopping the equipment to be controlled in stages during DR execution.
FIG. 17 is a diagram illustrating a specific example of the rebound effect when the stepwise DR is executed.
In FIG. 17, the DR execution period is the time between time t ₁₂ and time t ₁₅ . Reference numeral 30 represents power consumption when normal DR is executed. The rebound amount of the rebound effect caused by normal DR is R. Reference numeral 31 represents a power consumption in the case of the conventional DR start time t ₁₂ earlier than the time t ₁₁ to stop the equipment to be stepwise controlled. In this case, the temperature change of the control target of the building at the end time t ₁₅ of the DR is smaller than the normal DR is performed. Therefore, when the controlled object facility is stopped as indicated by reference numeral 31 at the time of DR execution, the amount of rebound that occurs is smaller than that at the time of normal DR execution.

Further, reference numeral 32 is stepwise the controlled installation is stopped from the start time t ₁₂ the normal DR, representing the power consumption when stopping the number of the controlled installation than conventional DR. In this case, the temperature change of the control target of the building at the end time t ₁₅ of the DR is smaller than the normal DR is performed. Therefore, when the controlled equipment is stopped as indicated by reference numeral 32 at the time of DR execution, the amount of rebound that occurs compared to the time of normal DR execution is reduced.

The configuration described above is not necessarily applied to the VPP system. Similarly, the configuration described above is not necessarily applied to a system in which a demand response is executed. In other words, the configuration described above can be applied to all systems that limit and cancel operations of a plurality of facilities to be managed in order to reduce power consumption. This restriction of operation is a restriction such as stopping and starting of equipment based on the above-described demand response and power saving operation.
In the first embodiment, a target on which each facility is installed does not necessarily need to be a building, and may be any facility as long as power consumption by a plurality of facilities is managed in common. . For example, an object on which each facility is installed may be a museum, a leisure facility (for example, a ski resort, a baseball field, etc.), or a facility including a parking lot.
In the second embodiment, the objects managed by the system do not necessarily need to be a plurality of buildings, and may be any area as long as the power consumption by a plurality of facilities is managed in common. . For example, it may be an area having a plurality of facilities such as a university, a hospital or an industrial area, or an administrative area such as a municipality.
The rebound time in the first embodiment and the second embodiment does not necessarily need to be the time for which the rebound effect continues, even if it is the time from the start of the managed equipment or facility to the peak of power consumption. Good.

According to at least one embodiment described above, DR control that controls the start-up of each equipment after the delay time acquired for each equipment in the facility elapses with reference to the timing when the equipment stoppage in the facility ends. By having a portion, an increase in power consumption per unit time due to the rebound effect can be suppressed.

Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention.
