Description

  The present invention relates to a control device for equipment.

  In recent years, there has been a widespread movement in which energy suppliers work on a plurality of properties that are users to control energy consumption during times of high energy demand and to efficiently operate energy supply facilities.

  For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2005-107901), a power supplier monitors the usage status of a user's electrical equipment, and when the power supply and demand is tight, the needs of the power supplier and the user's predetermined electricity A system has been proposed in which a user's electrical device is stopped based on a priority order regarding the stop of the device.

  Note that when the energy consumption of the property is controlled, the user's comfort is likely to be impaired, and thus it is necessary to consider the user's comfort. For example, in Patent Document 2 (Japanese Patent Application Laid-Open No. 2004-116820), when energy saving control of equipment is performed, if it is determined that the user's comfort is impaired, the control considering the comfort from the energy saving control is performed. A system that can be switched to is proposed.

  However, when the energy suppression control is canceled according to the user's comfort as in Patent Document 2, the energy consumption may not be sufficiently suppressed. If energy consumption is not sufficiently controlled, the user will suffer the disadvantage of increased energy prices, and depending on the contract with the energy supplier, the penalty may be paid as a penalty for not being able to sufficiently suppress energy consumption. There is a possibility that obligations may arise.

  The subject of this invention is providing the control apparatus of the equipment which can aim at the achievement of the target of energy consumption suppression, and a user's comfort, when a property receives the suppression request | requirement of energy from an energy supplier. is there.

  A control device according to a first aspect of the present invention is a control device that controls equipment, and includes a reception unit, a control unit, a grasping unit, a performance value determination unit, and a first release unit. The reception unit receives an energy suppression request or energy unit price distribution from a management device of an energy supplier that supplies energy to the equipment. A control part performs suppression control of energy consumption according to the suppression request | requirement or unit price delivery. The grasping unit grasps one or more result values as the results of the suppression control. The actual value determination unit determines whether a part or all of the actual values satisfy a target level set for each actual value. A 1st cancellation | release part cancels | releases execution of suppression control based on the determination result of a performance value determination part.

  Here, the actual value of the energy suppression control is grasped, and the execution of the energy suppression control is canceled on the condition that the actual value satisfies the target level. If the actual value does not satisfy the target level, the execution of the suppression control is not canceled, so it is easy to achieve both comfort and energy suppression.

  The control device according to the second aspect of the present invention is the control device according to the first aspect, and the actual value includes an amount of energy reduced, a reduced energy price, or an accumulated time of suppression control in the first predetermined period. Including at least one. The actual value determination unit determines that the actual value satisfies the target level when the actual value exceeds a predetermined value.

  Here, at least one of the reduced energy amount, the reduced energy price, or the accumulated time of the suppression control is used as the actual value. By using these values as actual values, it is expected that the user can easily realize the results of the energy suppression control and can induce further energy suppression of the user.

  The control apparatus which concerns on the 3rd viewpoint of this invention is a control apparatus which concerns on the 1st or 2nd viewpoint, Comprising: A grasping | ascertainment part grasps | ascertains a performance value for every installation apparatus individually and / or for each group. The actual value determination unit determines whether the actual value satisfies the target level for each piece of equipment and / or for each group. A 1st cancellation | release part cancels | releases execution of suppression control for every installation apparatus and / or for every group. The equipment device group refers to, for example, a group classified according to the type of equipment, the installation location, the operation frequency, and the like, but the user may arbitrarily set the group.

  Here, it is determined whether the actual value satisfies the target level for each equipment and / or group, and the execution of the suppression control is canceled for each equipment and / or group. Highly flexible energy suppression control is easily realized.

  The control apparatus which concerns on the 4th viewpoint of this invention is a control apparatus which concerns on a 3rd viewpoint, Comprising: A comfort determination part and a 2nd cancellation | release part are further provided. The comfort determination unit determines user comfort. A 2nd cancellation | release part cancels execution of suppression control about all or one part of equipment, when the comfort determination part determines that comfort is not satisfy | filled in addition to the determination result of a performance value determination part. .

  Here, in addition to the fact that the actual value satisfies the target level, the energy suppression control is released only when it is determined that the user's comfort is not satisfied. When the user's comfort is satisfied, it is expected that the actual value will be further increased.

A 1st cancellation | release part cancels execution of suppression control based on the determination result of a track record value determination part, and the determination result of a prediction track record value determination part.

  Here, since the execution of the suppression control is canceled in consideration of the predicted actual value after the lapse of the predetermined period, even if the actual value has once reached the target level, the actual value is obtained after the lapse of the predetermined period by canceling the suppression control. It is possible to prevent the value from reaching the target level.

  A control device according to an eighth aspect of the present invention is the control device according to the seventh aspect, further comprising a mitigation unit. The mitigation unit relaxes the suppression control based on the determination result of the predicted performance value determination unit. The relaxation unit relaxes the suppression control based on the determination result of the actual value determination unit when the execution of the suppression control is not canceled by the first cancellation unit.

  Here, since the suppression control is relaxed even when the execution of the suppression control is not cancelled, the user's comfort is easily improved. Further, since the execution of the suppression control is not canceled, it is easy to prevent the actual value from reaching the target level after a predetermined period.

  A control device according to a ninth aspect of the present invention is a control device according to any one of the first to sixth aspects, wherein the energy consumption prediction unit, the actual value prediction unit, the predicted actual value determination unit, A delay unit. The energy consumption amount prediction unit predicts the transition of the energy consumption amount in the third predetermined period. The actual value predicting unit predicts the actual value after the third predetermined period as the predicted actual value based on the transition of the energy consumption predicted by the energy consumption predicting unit. The predicted actual value determination unit determines whether a part or all of the predicted actual value satisfies a target level set for each actual value. The delay unit delays cancellation of execution of the suppression control by the first cancellation unit for a predetermined time. A delay part delays cancellation | release of execution of the suppression control by a 1st cancellation | release part based on the determination result of a prediction performance value determination part.

  Here, since the execution release of the suppression control is delayed in consideration of the predicted actual value after the lapse of the predetermined period, the actual value is determined after the lapse of the predetermined period as compared with the case where the suppression control is canceled based on only the current actual value. It is easy to prevent the target level not being reached.

  In the control device according to the first aspect of the present invention, the actual value of the energy suppression control is grasped, and the execution of the energy suppression control is canceled on the condition that the actual value satisfies the target level. Since the suppression control is not released unless the actual value satisfies the target level, it is easy to achieve both the achievement of the target of energy consumption reduction and comfort.

  In the control device according to the second aspect of the present invention, a value at which the user can easily feel the result of the energy suppression control is selected as the actual value. If the user can realize the result of the suppression control, it is easy to induce further energy suppression.

  In the control device according to the third aspect of the present invention, it is possible to grasp the actual value and release execution of the suppression control for each equipment and / or group, and it is easy to realize highly flexible suppression control.

  In the control device according to the fourth aspect of the present invention, the execution of the energy suppression control is canceled only when it is determined that the user's comfort is not satisfied in addition to the achievement value achieving the target level. When the user's comfort is satisfied, the achievement value is further increased.

  In the control device according to the fifth aspect of the present invention, for the air conditioners that have a relatively large impact on the user comfort among the equipment, the suppression control is canceled from the viewpoint of achieving the target level of the actual value and ensuring the comfort. Is determined.

  In the control device according to the sixth aspect of the present invention, when the remaining time of the suppression control is short, the recovery of comfort is expected after completion of the suppression control even if the further actual value is increased. The user's comfort is hardly affected.

  In the control device according to the seventh aspect of the present invention, the actual value can be prevented from reaching the target level.

It is used as it is as the electric power and electric energy every hour until the hour. The energy price is calculated by multiplying the hourly power consumption of the previous day by the power unit price. In the present embodiment, the information is hourly information, but the power, the electric energy, and the energy price may be predicted at shorter time intervals or longer time intervals.

  Note that the prediction method is not limited to the above method. For example, the hourly power, power amount, and energy price may be calculated statistically from the information for the past week. Further, instead of or in addition to the past information, for example, the power, the electric energy, and the energy price may be predicted based on data such as the weather forecast for the day.

(2-2-6-3) Adjustment control unit 36c
The adjustment control unit 36c executes different suppression control depending on the magnitude relationship between the energy suppression request amount and a second energy suppression possible amount described later.

(A) In the case where the second energy suppression possible amount ≦ the energy suppression required amount When the second energy suppression possible amount is equal to or less than the energy suppression required amount, that is, on the condition used for calculating the second energy suppression possible amount, When it is likely to be reduced below the required energy suppression amount, the suppression control is executed under the conditions used for calculating the second energy suppression possible amount.

  For example, if the condition is to reduce the current energy consumption by 10% over 60 minutes, the suppression control is executed to reduce the energy consumption of the equipment by 10% compared to before the start of the second adjustment control. .

(B) When second energy suppression possible amount> energy suppression required amount When the second energy suppression possible amount is larger than the energy suppression required amount, that is, under the conditions used for calculating the second energy suppression possible amount, the maximum power Is not reduced below the required energy suppression amount, the suppression control is executed using the conditions of the second condition storage area 35f.

  Suppression control is executed. By using the conditions of the second condition storage area 35f, more energy consumption is suppressed than when the suppression control is executed under the conditions used for calculating the second energy suppression possible amount.

(2-2-6-4) Calculation unit 36d
The calculation unit 36d calculates the first energy suppression possible amount using the condition stored in the first condition storage area 35b. The calculated first energy suppression possible amount is stored in the transmission storage area 35h together with the calculation condition.

  When the condition is the intensity of energy suppression, the first energy suppression possible amount is calculated as follows, for example. In this embodiment, for example, as shown in FIG. 4, a plurality of combinations of the control time length and the energy consumption reduction rate are stored as conditions.

  First, the calculation unit 36d calls the electric power [kW] immediately before the calculation of the first energy suppression possible amount from the driving situation storage area 35a. At the same time, the calculation unit 36d calls the conditions stored in the first condition storage area 35b. Thereafter, the calculation unit 36d calculates the first energy suppression possible amount PE1 for each condition. The first energy suppression possible amount PE1 is represented by the following equation.

  (Formula 1) PE1 = p × (1-k)

  Here, p represents the power [kW] immediately before the calculation of the first energy suppression possible amount, and k represents the energy consumption reduction rate [%]. Note that the predicted power stored in the predicted amount storage area 35e may be used for p instead of the power immediately before the calculation of the first energy suppression possible amount.

  A case where the electric power immediately before the calculation of the first energy suppression possible amount is used for calculation of the first energy suppression possible amount PE1 will be described with a specific example.

  For example, it is assumed that the electric power immediately before the first energy suppression possible amount calculation called from the driving situation storage area 35a is 100 kW, and FIG. 4 is stored in the first condition storage area 35b. At this time, the first energy suppression possible amount PE1 is calculated as 80 kW, 90 kW, and 95 kW for the control time of 30 minutes, 60 minutes, and 120 minutes, respectively.

  PE1 may be weighted as in the following equation.

  (Formula 2) PE1 = p * (1-k) * m1 * m2 * ... * mN

  Here, m1, m2,..., MN are, for example, the time when the suppression control is performed, the predicted power, the predicted power amount, the predicted energy price, the state value of the indoor environment, the environmental condition, the operating state of the equipment, and It is a weighting coefficient related to the achievement status of the actual value grasped by the achievement grasping unit 36f with respect to the target level. The number of weighting factors may be one or plural.

  The condition may relate to a suppression control method. In this case, the first energy suppression possible amount is calculated as follows, for example.

  The calculation unit 36d calls the control method stored in the first condition storage area 35b of the facility device as a condition, and calculates a first energy suppression possible amount that can be minimized. For example, the first energy suppression possible amount PE1 can be expressed by Equation 3.

  (Formula 3) PE1 = Max (a1t * R1 + a2t * R2 + ... + aXt * RX)

  Here, R1, R2,... RX is the rated capacity [kW] of each of the X equipment. a1t, a2t,... aXt are determined by the On / Off of the equipment in a certain time zone t in the time zone for which the first energy suppression possible amount is calculated. Defined as 0.

  Specifically, the case where the control schedule of FIG. 5 is stored as a condition in the first condition storage area 35b will be described as an example.

  In FIG. 5, there are four time zones every 15 minutes. When (a1 × R1 + a2 × R2 +... + A7 × R7) is calculated for each time zone, they are 70 kW, 80 kW, 75 kW, and 75 kW. Among these, since the maximum value is 80 kW, the first energy suppression possible amount PE1 is calculated as 80 kW.

  Note that Expression 3 may be weighted in the same manner as Expression 2. Description is omitted.

(2-2-6-5) Presentation unit 36e
The presentation unit 36e presents the management device 10 with one or more first energy suppression possible amounts calculated by the calculation unit 36d and stored in the transmission storage area 35h together with the suppression possible time.

(2-2-6-6) Results grasping part 36f
The result grasping part 36f grasps the result of energy suppression control as a result value. The actual value is, for example, a reduced energy amount, a reduced energy price, or an accumulated time of executed suppression control. In addition, although the track record value grasped | ascertained is one in this embodiment, multiple may be sufficient. The target storage area 35g stores a target level corresponding to the amount grasped by the record grasping unit 36f. Information grasped by the record grasping unit 36f is stored in the control information storage area 35d.

  In the present embodiment, the actual value is grasped for the entire equipment, but the actual value may be grasped for each group of equipment. For example, the actual value may be grasped according to the type of equipment or the installation floor of equipment. The group may be set freely by the user by inputting from the input unit 33. Based on the information in the operating status storage area 35a, the equipment may be grouped according to the operating status of the equipment, for example, the operating frequency. When grasping the actual value for each group, the target level stored in the target storage area 35g may also be set for each group.

  Furthermore, a performance value may be grasped | ascertained with respect to each installation apparatus, and the target level memorize | stored in the target storage area 35g may be set for every installation apparatus.

(2-2-6-7) Discriminator 36g
The determination unit 36g determines a condition when the first energy suppression possible amount corresponding to the energy suppression request amount distributed from the management device 10 is calculated. Specifically, the distributed information is compared with the information stored in the transmission storage area 35h, and the corresponding calculation condition is determined.

(2-2-6-8) Recalculation unit 36h
The recalculation unit 36h calculates the second energy suppression possible amount under the same conditions as those determined by the determination unit 36g. Note that the same condition as the condition determined by the determination unit 36g is a condition in which the condition at the time of calculating the second possible energy suppression amount is reflected in the condition at the time of calculating the first possible amount corresponding to the required energy suppression amount. Therefore, both conditions may not match.

  Specific examples will be described.

  For example, it is assumed that the conditions relating to the energy consumption suppression rate of FIG. 8 are stored in the first condition storage area 35b, and the outside air temperature was 35 ° C. when calculating the first energy suppression possible amount. In this case, at the time of calculating the first energy suppression possible amount, the suppression rate of the energy consumption with respect to each control time is 20%, 10%, and 5%. On the other hand, for example, it is assumed that the outside temperature at the time of calculating the second energy suppression possible amount is 40 ° C. In this case, the suppression rate of energy consumption is 16%, 8%, and 4% for each control time.

  Therefore, when the management apparatus 10 selects the first energy suppression possible amount corresponding to the control time of 60 minutes as the energy suppression request amount for the presentation of the first energy suppression possible amount, the energy consumption is calculated when calculating the first energy suppression possible amount. Although the amount suppression rate is 10%, it is 8% when calculating the second energy suppression possible amount.

  In addition, the calculation method itself of the 2nd energy suppression possible amount is the same as that of the calculation part 36d.

  For example, when the condition is an energy consumption suppression rate, the second energy suppressible amount PE2 is calculated by the following Expression 4 or Expression 5.

(Formula 4) PE2 = p ′ × (1−k ′)
(Formula 5) PE2 = p ′ × (1−k ′) × m1 ′ × m2 ′... × mN ′

  Here, p ′ is the power [kW] immediately before the second energy suppression possible amount calculation. k 'is the energy consumption suppression rate under the same conditions as those determined by the determination unit 36g. mN ′ is a weighting factor. If the weighting factor mN ′ in Equation 5 varies depending on the state at the time of calculation, the weighting factor mN ′ may also be different from the weighting factor mN at the time of calculating the first energy suppression possible amount.

(2-2-6-9) Actual value determination unit 36i
The actual value determination unit 36i compares the actual value stored in the control information storage area 35d with the target level stored in the target storage area 35g. In addition to determining whether the actual value has achieved the target level, the achievement rate of the actual value with respect to the target level is also calculated.

  In this embodiment, the achievement level target level achievement condition is determined for the entire equipment. However, for example, when the actual value is grasped by the type of equipment or by the installation floor of the equipment, the actual value may be determined by the type of equipment or by the installation floor. . Moreover, you may perform determination of a performance value separately for equipment.

(2-2-6-10) First release unit 36j
The first cancellation unit 36j instructs the adjustment control unit 36c to cancel the execution of the suppression control when the actual value determination unit 36i determines that the actual value has achieved the target level. In this embodiment, equipment other than the air conditioners 40, 40,... Is controlled by the first release unit 36j, but the air conditioners 40, 40,. It may be targeted.

  In this embodiment, the 1st cancellation | release part 36j commands execution cancellation | release of suppression control collectively with respect to installation apparatuses other than air conditioner 40,40, .... However, when the actual value determination unit 36i knows the actual value for each group or for each facility device, the suppression control is performed for each facility device group such as each facility device type or for each facility device. Execution cancellation may be commanded.

(2-2-6-11) Comfort determination unit 36k
The comfort determination unit 36k determines the user comfort based on the driving situation stored in the driving situation storage area 35a. Comfort is determined, for example, by the degree of deviation between the set temperature of the air conditioner and the actual room temperature.

  In this embodiment, only the air conditioners 40, 40,... Are determined as comfort determination targets, but the comfort may be determined for other equipment. In this case, for example, the illumination is 50, 50,..., The illuminance, and the ventilation fans 60, 60,.

  Moreover, in this embodiment, although the comfort is grasped | ascertained as the whole property, for example, it is individual apparatus, for example, air conditioner 40,40, ... separate (indoor unit 42,42, ... separate or outdoor unit 41). , 41,...), Or by equipment equipment group, such as by floor or by operation frequency.

(2-2-6-12) Second release portion 36l
The second release unit 36l adjusts when the actual value determination unit 36i determines that the actual value has achieved the target level, and the comfort determination unit 36k determines that the comfort is impaired. The control unit 36c is instructed to cancel execution of the suppression control. In this embodiment, only the air conditioners 40, 40,... Are controlled by the second release unit 36l, but other equipment may also be controlled by the second release unit 36l.

  In the present embodiment, the second release unit 36l collectively commands the release of the suppression control of the air conditioners 40, 40,... For the entire property, but for example, for each device (for example, the air conditioners 40, 40,...・ Order to cancel execution of suppression control separately (for indoor units 42, 42,... Or for outdoor units 41, 41,...) May be.

(3) Control Process Performed by Energy Management System 100 FIG. 9 is a flowchart showing a flow of presentation of the first energy suppression possible amount to the management apparatus 10 mainly in the control apparatus 30. FIGS. 10 a and 10 b are flowcharts showing the flow of suppression control processing in the control device 30. The processes shown in FIGS. 9 and 10a and 10b are independent of each other. Hereinafter, the flow of processing in the control device 30 that controls equipment is described with reference to FIGS. 9 and 10a and 10b.

  First, FIG. 9 will be described.

  In this embodiment, step S101 is performed every day at 10 am. In step S101, the first energy suppression possible amount is calculated by the calculation unit 36d based on the power immediately before 10:00 am and the condition stored in the first condition storage area 35b. The calculated first energy suppression possible amount is stored in the transmission storage area 35h. Note that the predicted power calculated in step S103 may be used to calculate the first energy suppression possible amount, but in this case, step S103 is executed first, and the start time of step S101 is the same as that of step S103. After the end (for example, 10:10 am).

  In step S102, the presentation unit 36e calls the first energy suppression possible amount from the transmission storage area 35h and presents it to the management device 10.

  In step S103, after 10:00 am (10:05 am in the present embodiment), the prediction unit 36b calls information from 10:00 am on the previous day to 10:00 am on the current day from the driving state storage area 35a, Predict power, amount of electricity and energy price from 10:00 to 10:00 am the next day. The predicted amount is stored in the predicted amount storage area 35e.

  If it is determined in step S104 that it is 10 am, step S101 is executed again.

  On the other hand, even if it is not 10:00 am, if it is determined in step S105 that the management device 10 has requested transmission of the first energy suppression possible amount, the first energy suppression possible amount is calculated in step S106 and transmitted. It is stored in the storage area 35h. Thereafter, in step S107, the presentation unit 36e presents the first energy suppression possible amount to the management device 10.

  When there is no transmission request, it waits until 10:00.

  Next, FIGS. 10a and 10b will be described.

  In step S111, the communication unit 31 receives an energy consumption suppression request from the management device 10 together with the energy suppression request amount, and stores the request in the request storage area 35c. The timing of the suppression request is irregular.

  In step S112, based on the information distributed from the management apparatus 10, the determination unit 36g determines a calculation condition for the first energy suppression possible amount corresponding to the distributed energy suppression request amount.

  In step S113, the recalculation unit 36h calculates the second energy suppression possible amount (PE2 in FIG. 10a) under the same conditions as those determined in step S112.

  In step S114, the second energy suppression possible amount (PE2) is compared with the energy suppression request amount (D in FIG. 10a) stored in the request storage area 35c.

  If the result of step S114 is the second energy suppression possible amount (PE2) ≦ the energy suppression required amount (D), the suppression control starts using the conditions used for calculating the second energy suppression possible amount in step S115. Is done. At this time, the start time of the suppression control is stored in the control information storage area 35d. During the suppression control, the record value is grasped by the record grasping unit 36f in step S116. The record value grasped by the record grasping part 36f is stored in the control information storage area 35d. In step S117, it is determined whether the actual value has achieved the target level stored in the target storage area 35g. Step S116 and step S117 are repeatedly executed every predetermined period (every 5 minutes in the present embodiment) until it is determined in step S118 that the suppression request time has ended. If it is determined in step S117 that the target level has been achieved, in step S119, the first release unit 36j orders the release of the suppression control for equipment other than the air conditioners 40, 40,. (First release). The time when the first release is executed is stored in the control information storage area 35d. If the actual value has achieved the target level, the comfort determination unit 36k determines comfort in step S120. Step S120 is repeatedly executed until it is determined in step S121 that the suppression request time has ended. If it is determined that the comfort is not satisfied, in step S122, the second release unit 36l commands release of the suppression control of the air conditioners 40, 40,. At the end of the suppression control, the time when the suppression control is released and the amount of power reduced through the suppression control are stored in the control information storage area 35d.

  In addition, for example, for each type of equipment, for each equipment location, and for each equipment, the actual value is ascertained and the achievement level of the target level is determined, and each equipment type, equipment location, and equipment When canceling the suppression control for each device, a plurality of steps S116 to S122 are performed as shown in FIG. In this case, when there is only an equipment device whose execution of suppression control is canceled by the first cancellation, steps S120 to S122 are not necessary. Step S119 is unnecessary when there is only an equipment device whose suppression control is canceled by the second cancellation.

  On the other hand, when the second energy suppression possible amount (PE2)> the energy suppression required amount (D), suppression control is started using the condition of the second condition storage area 35f in step S135. In step S135, the start time of the suppression control is stored in the control information storage area 35d. Steps S136 to S142 are the same as steps S116 to S122, respectively, and a description thereof will be omitted.

(4) Features (4-1)
In this embodiment, the control device 30 controls the equipment (air conditioners 40, 40,..., Lighting 50, 50,..., Ventilation fans 60, 60,...) The adjustment control unit 36c, the actual result grasping unit 36f, the actual result value determining unit 36i, and the first release unit 36j are provided. The communication unit 31 receives an energy suppression request from the management device 10 of the energy supplier that supplies energy to the equipment. The adjustment control unit 36c performs energy consumption suppression control in response to the suppression request. The result grasping unit 36f grasps one or a plurality of result values as the results of the suppression control. The actual value determination unit 36i determines whether a part or all of the actual values satisfy a target level set for each actual value. The first canceling unit 36j cancels the execution of the suppression control based on the determination result of the actual value determining unit 36i.

  The actual value of the energy suppression control is grasped, and the energy suppression control is canceled on the condition that the actual value satisfies the target level. Since the suppression control is not released unless the actual value satisfies the target level, it is easy to achieve both the comfort and achievement of the energy suppression control.

(4-2)
In the present embodiment, as the actual value of the energy suppression control, for example, a reduced energy amount, a reduced energy price, or an integrated time of suppression control during a predetermined period is used. The actual value determination unit 36i determines that the actual value has satisfied the target level when the actual value exceeds the value set as the target level.

  Setting the target level for the reduced energy amount, the reduced energy price, or the integration time of the suppression control makes it easier for the user to realize the results of the energy suppression control. If the user can realize the result, it is expected that further energy suppression control can be attracted.

(4-3)
The record grasping unit 36f may grasp record values individually for each equipment and / or for each group. At this time, the actual value determination unit 36i determines whether the actual value satisfies the target level for each equipment and / or for each group. The 1st cancellation | release part 36j cancels | releases execution of suppression control for every installation apparatus and / or for every group.

  Since it is possible to judge whether the actual value has reached the target level for each equipment and / or group, and the restraint control can be released for each equipment and / or group, highly flexible restraint control is realized. Cheap.

(4-4)
In this embodiment, the comfort determination part 36k and the 2nd cancellation | release part 36l are further provided. The comfort determination unit 36k determines user comfort. In addition to the determination result of the actual value determination unit 36i, the second release unit 36l performs suppression control on all or part of the equipment when the comfort determination unit 36k determines that the comfort is not satisfied. Cancel execution.

  Here, in addition to the achievement value achieving the target level, the execution of the energy suppression control is canceled only when it is determined that the user's comfort is not satisfied. If the user's comfort is satisfied, the suppression control is not canceled as much as possible, and the achievement value is further increased.

(4-5)
In particular, the comfort determination unit 36k determines comfort related to air conditioning. The second release unit 36l that uses the achievement of the target level of the actual value and the loss of comfort as the release condition of the suppression control is used only to cancel the execution of the suppression control of the air conditioners 40, 40,. . On the other hand, the 1st cancellation | release part 36j which makes a cancellation | release condition only achievement of the target level of a performance value is used for cancellation | release of execution of suppression control of equipment other than air conditioner 40,40, ....

  Among the equipment, air conditioning units 40, 40,... That have a relatively large impact on user comfort can be released from the two aspects of achievement of the target level of the actual value and ensuring of comfort. It is determined.

(5) Modification (5-1) Modification 1A
The calculation unit 36d and the recalculation unit 36h use the formula 1, the formula 2, the formula 4 or the formula 5 to calculate the first energy suppression possible amount or the second energy suppression possible amount to the power (kW) immediately before the calculation. Instead, for example, an average value of the electric energy per unit time for 30 minutes immediately before the calculation may be used. By referring to the driving situation for a certain period, it is possible to calculate an energy suppression possible amount that is closer to the actual value.

(5-2) Modification 1B
The control device 30 may not include the presentation unit 36e. In this case, the suppression request amount is distributed according to a contract determined between the power company and the contract between the power company and the user. The suppression control in this case is executed as follows, for example.

  The calculation unit 36d calculates the first energy suppression possible amount and compares it with the presented energy suppression request amount. Then, the calculation unit 36d finds a condition in which the first energy suppression possible amount> the energy suppression request amount can be satisfied from the first condition storage area 35b. The adjustment control unit 36c performs suppression control using the found condition. About cancellation | release of suppression control, it is the same as that of 1st Embodiment. In this case, the determination unit 36g and the recalculation unit 36h are also unnecessary.

(5-3) Modification 1C
The adjustment control unit 36c may not execute the suppression control when there is a possibility that the comfort cannot be ensured by executing the suppression control. For example, if the measured values of temperature and humidity have not reached the set values and are deviating more than predetermined, even though they are currently operating at a driving capacity of 100%, the suppression control is performed. It is not necessary to execute. In addition, for example, the control command may not be executed for a certain period of time after the start of operation.

(5-4) Modification 1D
When the actual value grasped by the actual result grasping part 36f is the reduced energy price, the calculation of the actual value is subject to a penalty or additional charge when the property fails to achieve the energy suppression requirement amount presented by the electric power company. Penalties may be considered.

  In addition, when the actual value grasped by the actual result grasping unit 36f is a reduced energy amount, when the energy amount is increased more than usual during the suppression control, the increase value is considered in calculating the actual value. Good.

  Specifically, for example, when using a reduced energy price as the actual value, the actual value is obtained by subtracting the amount to be paid as a penalty from the energy price that could be reduced by restraint control, and comparing that value with the target level. Also good.

(5-5) Modification 1E
The actual value determination unit 36i may execute the determination by comparing the future predicted actual value and the target level, instead of comparing the actual value to the present and the target level.

  Specifically, for example, using the predicted power predicted by the prediction unit 36b, the predicted power amount, the predicted energy price, and the like, the actual value is at the end time of the suppression control distributed by the management apparatus 10 of the power company. Determine whether the target level can be achieved.

  In this case, for example, even if the target level is achieved at the present time, if it is determined that the target level will not be achieved at the end time of the suppression control if the suppression control is canceled, the first cancellation unit 36j cancels the execution of the suppression control. Do not order.

(5-6) Modification 1F
The first release unit 36j and the second release unit 36l do not have to execute a command to release the suppression control when the remaining time of the suppression control is equal to or less than a predetermined value.

  Since recovery of comfort is expected after the suppression control is completed, if the remaining time is short, the accumulation of the actual value is given priority.

(5-7) Modification 1G
The adjustment control unit 36c may execute strong suppression control for ensuring responsiveness for a short period of time immediately after receiving a request, instead of executing uniform suppression control. Once the responsiveness is ensured, the suppression control that achieves both energy reduction and user comfort as described in the first embodiment is executed.

(5-8) Modification 1H
The user may be able to manually cancel the suppression control. However, also in this case, during the suppression control, the remaining time of the suppression control (end time of the suppression request time) and the actual value that can be achieved with the remaining time of the suppression control are output to the output unit 32. The current situation can be accurately grasped, and the suppression control is not easily released.

(5-9) Modification 1I
In the present embodiment, the first release unit 36j and the second release unit 36l are configured so that the actual value reaches the target level (if the second release unit 36l determines that the user's comfort is not satisfied). The execution of the suppression control is released, but in addition to this, a time period during which the execution of the suppression control cannot be released may be determined.

  Specifically, during the time period determined by the prior agreement between the power company 1 and the property A, for example, from 12:00 to 19:00, the first release unit 36j and the first Even if the execution cancellation condition of the suppression control of the 2 cancellation unit 36l is satisfied, the suppression control execution is not canceled.

  Thereby, the electric power company 1 can request not to cancel the execution of the suppression control in a time zone in which the power supply and demand is particularly severe, and can prevent a shortage of supplied power.

(5-10) Modification 1J
In the present embodiment, the first release unit 36j and the second release unit 36l release the execution of the suppression control when the condition is satisfied, but is not limited to this. For example, instead of releasing the suppression control The content of the suppression control may be changed.

  A specific example will be described.

  When the power company 1 requests the property A to perform suppression control, the power company 1 transmits the required suppression energy amount together with the suppression request energy amount. The amount of energy that must be suppressed is the amount of energy that the power company 1 requests the property A to reliably achieve. That is, the amount of energy required to be suppressed is an amount that the property A should always achieve in principle, while the amount of energy required for suppression has the meaning of a recommended value. If the 1st cancellation | release part 36j and the 2nd cancellation | release part 36l satisfy | fill the conditions shown in this embodiment, instead of suppressing an energy consumption to the suppression request | requirement energy amount, the suppression which suppresses an energy consumption to a required suppression energy amount Execute control.

  More specifically, it is assumed that the electric power company 1 transmits 80 kW as the required suppression energy amount and 90 kW as the required suppression energy amount when requesting the power suppression control for the property A that uses the maximum power of 100 kW. The property A first executes control for suppressing power to 80 kW, which is the required energy amount for suppression. After that, when the first release unit 36j and the second release unit 36l satisfy the conditions, suppression control that allows the power that has been reduced to 80 kW to be increased to 90 kW, which is a necessary suppression energy amount, is executed. In other words, the 1st cancellation | release part 36j and the 2nd cancellation | release part 36l change the content of suppression control instead of canceling execution of suppression control.

  Thereby, in the property A, since the actual value has reached the target level, it is possible to prevent a shortage of power supplied by the power company 1 even when the user's comfort is restored.

Second Embodiment

(2-2-4) Control unit 236
The control unit 236 mainly includes a CPU, a ROM, and a RAM. As shown in FIG. 14, the control unit 236 reads and executes the program stored in the above-described storage unit 235, thereby mainly operating state grasping unit 236a, prediction unit 236b, adjustment control unit 236c, and calculation unit. 236d, a determination unit 236e, a result grasping unit 236f, a supplier company instruction unit 236g, a recalculation unit 236h, a result value determination unit 236i, a first release unit 236j, a comfort determination unit 236k, and a second release unit 236l. 236a, 236f, 236i, 236j, 236k, and 236l have the same configurations as 36a, 36f, 36i, 36j, 36k, and 36l of the first embodiment, respectively. Therefore, the prediction unit 236b, the adjustment control unit 236c, the calculation unit 236d, the determination unit 236e, the supplier company instruction unit 236g, and the recalculation unit 236h will be described below.

(2-2-4-1) Prediction unit 236b
In the present embodiment, for example, the energy consumption is predicted for the energy at 9:05 am. The calculation of the energy price that has been executed in the prediction unit 36b is not executed by the prediction unit 236b. Other points are the same as those of the prediction unit 36b of the first embodiment.

(2-2-4-2) Adjustment control unit 236c
The adjustment control unit 236c executes different suppression control based on the target level stored in the target storage area 235k and the result of the magnitude comparison of the second possible amount described later.

(A) When the second possible amount is equal to or higher than the target level When the second possible amount is equal to or higher than the target level, that is, when the target level is likely to be achieved, the condition stored in the first condition storage area 235b is used. Then, the suppression control is executed.

(B) When the second possible amount is smaller than the target level When the second possible amount is smaller than the target level, that is, when the target level is unlikely to be achieved under the conditions of the first condition storage area 35b, the second condition The suppression control is executed using the conditions stored in the storage area 235g.

(2-2-4-3) Calculation unit 236d
The calculating unit 236d calculates the first possible amount. The first possible amount relates to an amount that is to be grasped as a result of energy suppression control by the result grasping unit 236f described later and the same amount as the target level stored in the target storage area 235k. That is, for example, if the amount and target level to be grasped by the result grasping unit 236f are the amount of energy reduction per suppression control, the first possible amount is also the amount of energy reduction per suppression control [kWh / Times]. In addition, if the amount and target level to be grasped by the result grasping unit 236f are energy reduction prices per one suppression control, the first possible amount is also the energy reduction price per one suppression control [yen / Times].

  In the present embodiment, the amount and the target level that are to be grasped by the achievement grasping unit 236f are energy reduction amounts per one suppression control. The first possible amount P1 is expressed by the following equation, for example. In the present embodiment, the condition of the first condition storage area 235b is a reduction rate of energy consumption, and is determined according to the length of a candidate time zone described later.

  (Formula 6) P1 [kWh / time] = p × k × ΔT

  Here, p is the power [kW] immediately before the first possible amount calculation, k is the energy consumption reduction rate determined by the length of the candidate time zone [%], and ΔT is the length of the candidate time zone [time]. Represents.

  For example, when the target level is a reduction price of energy per one suppression control, the first possible amount P1 is expressed by the following equation, for example.

  (Expression 7) P1 [yen / time] = Σ (p × k × cn × ΔTn)

  Here, cn is the energy unit price [yen / kWh] of the nth time zone when the energy unit price varies according to the time zone in the candidate time zone, and ΔTn is the length of the nth time zone [ Time].

  Note that p may use the predicted power predicted by the prediction unit 236b instead of the power immediately before the calculation of the first possible amount P1.

  The calculated first possible amount is displayed on the output unit 232 so that the user can grasp in advance whether the target level is likely to be achieved. Further, for example, the target level of the actual value stored in the target storage area 235k may be updated using the first possible amount.

  Note that the condition of the first condition storage area 235b used by the calculation unit 236d to calculate the first possible amount is not related to the energy suppression strength, but may be a suppression control method.

(2-2-4-4) Determination unit 236e
The determination unit 236e mainly performs two processes of determining a candidate time zone for which suppression control should be performed and calculating a predicted energy price.

  The candidate time zone is determined as follows.

  The determination unit 236e uses the lowest unit price information created from the unit price information for one or more time zones received by the communication unit 231 to perform suppression control within a predetermined period (one day in the present embodiment). The candidate time zone in which to execute is determined.

  The cheapest unit price information is information that is determined by the determination unit 236e as described below and stored in the lowest unit price storage area 235j.

  When a plurality of unit price information exists in the same time zone, the determination unit 236e compares the energy unit price of each power company and determines the lowest unit price (lowest energy unit price) for each time zone. The determined lowest unit price information for each time zone is stored in the lowest unit price storage area 235j together with the name of the power company providing the lowest unit price as shown in FIG.

  In addition, in the present embodiment, the determination unit 236e determines a time zone in which the energy unit price is maximum from among the lowest unit price information throughout the day as a candidate time zone.

  However, the candidate time zone is not limited to the time zone in which the energy unit price is maximum. For example, the determination unit 236e may select a time zone in which the energy unit price exceeds a predetermined value and determine the candidate time zone. Note that the predetermined value may be a fixed value, or may be a value that is appropriately input by the user from the input unit 233 and updated. The predetermined value may be a value that is appropriately calculated by the determination unit 236e from unit price information such as an average value or an intermediate value of energy unit prices.

  Below, the determination method of a candidate time slot | zone is concretely demonstrated about the case where the time slot | zone where an energy unit price becomes the maximum within a predetermined period as a candidate time slot | zone of this embodiment. Here, a case where there are a plurality of electric power companies will be described.

  First, in the present embodiment, the determination unit 236e reads unit price information of a plurality of energy from 9:00 am on the current day to 9:00 am on the next day, which exists in the unit price storage area 235i, at 9:00 am. And the energy unit price of each electric power company is compared according to a time slot | zone, the cheapest unit price information like FIG. 15 is produced, and it memorize | stores in the cheapest unit price storage area 235j.

  In addition, the determination unit 236e determines, as a candidate time zone, a time zone in which the energy unit price is maximum within a predetermined period, based on information stored in the lowest unit price storage area 235j. For example, in the example of FIG. 15, the determination unit 236e is a time zone in which the energy unit price is the maximum from 13:00 to 16:00 on the current day within a predetermined period (the period from 9:00 am on the current day to 9:00 am on the next day). Determines from 13:00 to 16:00 on that day as a candidate time zone.

  Next, the calculation process of the predicted energy price performed by the determination unit 236e will be described.

  The determination unit 236e calculates a product of the unit price information stored in the cheapest unit price storage area 235j and the amount of power predicted by the prediction unit 236b. As a specific process, the determination unit 236e reads the unit price information stored in the cheapest unit price storage area 235j and the prediction power amount information stored in the prediction amount storage area 235e, and calculates a product by time. . The created information is stored in the predicted price storage area 235f. FIG. 16 is an example of information stored in the predicted price storage area 235f.

  By outputting the predicted energy price calculated in this way to the output unit 232, the user can know the price of energy predicted in advance. Further, the predicted energy price may be used for determining the candidate time zone. For example, in FIG. 16, from 13:00 to 15:00 when the predicted energy price is maximum may be determined as the candidate time zone.

(2-2-4-5) Supply company instruction section 236g
Based on the data stored in the cheapest unit price storage area 235j, the supply company instructing unit 236g gives an instruction to a switchboard (not shown) to purchase power from the cheapest power supply company hourly.

(2-2-4-6) Recalculation unit 236h
The recalculation unit 236h calculates the second possible amount under the conditions stored in the first condition storage area 235b.

  The calculation method is the same as that of the calculation unit 236d.

(3) Control Process Performed by Energy Management System 200 FIG. 17 is a flowchart mainly showing a flow of determination of candidate time zones in the control device 230. 18a and 18b are flowcharts showing the flow of suppression control processing in the control device 230. The processes shown in FIGS. 17 and 18a and 18b are independent of each other. Hereinafter, the flow of processing in the control device 30 for controlling the equipment will be described with reference to FIGS. 17 and 18a and 18b.

  First, FIG. 17 will be described.

  In this embodiment, step S201 is performed every day at 9:00 am. In step S201, the determination unit 236e reads unit price information from 9:00 am on the current day to 9:00 am on the next day from the unit price storage area 235i.

  The unit price information is distributed from the management devices 210 and 210 of one or more power companies S and T to the control device 230 of the property A at a predetermined time interval (one day interval in this embodiment). In the present embodiment, unit price information from 9:00 am on the current day to 9:00 am on the next day is distributed at 7:00 am. The distributed unit price information is stored in the unit price storage area 235i.

  In step S202, the determination part 236e compares the energy unit price of each electric power company according to time slot | zone based on the energy unit price information read by step S201, and determines the cheapest unit price according to time slot | zone. When there is only one electric power company, the distributed unit price information is determined as the lowest unit price information as it is. The lowest unit price for each time zone is stored in the lowest unit price storage area 235j together with the name of the electric power company that presents the lowest unit price.

  In step S203, after 9 am (9:05 am in the present embodiment), the prediction unit 236b reads the past energy consumption from the operating state storage area 235a, and for a predetermined period (9 am on the current day in the present embodiment). Time-by-hour power and power amount prediction from the hour to the next day at 9:00 am is executed. The predicted power and power amount are stored in the predicted amount storage area 235e.

  In step S204, the determination unit 236e uses the information on the cheapest unit price information in the lowest unit price storage area 235j and the predicted power amount in the predicted amount storage area 235e to calculate the product of the unit price for each hour and the predicted energy consumption. Ask for. As a result, for example, a table of predicted energy prices for each hour as shown in FIG. 16 is created. A table of predicted energy prices is stored in the predicted price storage area 235f.

  In step S205, the determination unit 236e determines a candidate time zone in which the energy unit price is the maximum in the predetermined period from 9 am on the current day to 9 am on the next day. For the determination, the cheapest unit price information stored in the cheapest unit price storage area 235j is used. The candidate time zone is not limited to one within the predetermined period. The start time and end time of the determined candidate time zone are stored in the candidate time zone storage area 235h. Instead of the energy unit price, the predicted energy amount stored in the predicted amount storage area 235e or the predicted energy price stored in the predicted price storage area 235f may be used for determining the candidate time zone.

  In step S206, the calculation unit 236d calculates the first possible amount using the power just before the calculation stored in the driving situation storage area 35a and the condition called from the first condition storage area 235b. The calculated first possible amount is output to the output unit 232. For the calculation of the first possible amount, for example, the predicted power calculated by the prediction unit 236b in the candidate time zone determined in step S205 may be used instead of the power immediately before the calculation.

  In addition, the user can grasp | ascertain an indication whether the performance value of energy suppression control is likely to achieve the target level based on the output of the first possible amount. If the target level can be updated, the target level may be updated with reference to the output.

  In step S207, the time of the time management unit 234 is used to determine whether the time has reached 9:00 am. When the time is 9:00 am, step S201 is executed, and the process waits until then.

  However, if the communication unit 231 determines that an urgent change in energy unit price has been received in step S208, in steps S209, S210, S211, S212, and S213, steps S201, S202, S204, and S205, respectively. And the operation of S206 is executed. In steps S209 to S213, the time from the emergency unit price delivery reception time to 9:00 am the next time is set as the candidate time zone determination target.

  Next, FIGS. 18a and 18b will be described.

  In step S221, the recalculation unit 236h uses the current time of the time management unit 234 and the information stored in the candidate time zone storage area 235h to reach the start time of the candidate time zone within 5 minutes. Determine.

  In step S222, the recalculation unit 236h calculates the second possible amount (P2 in FIG. 18a) with reference to the driving situation storage area 235a and the first condition storage area 235b. Note that, for the calculation of the second possible amount, for example, the predicted power calculated by the prediction unit 236b may be used instead of the power immediately before the calculation.

  In step S223, the target level (TL in FIG. 18a) stored in the target storage area 235k is compared with the second possible amount (P2) calculated by the recalculation unit 236h, and the content of the suppression control of the adjustment control unit 236c is determined. decide.

  If the result of step S223 is the second possible amount (P2) ≧ target level (TL), suppression control is executed under the conditions stored in the first condition storage area 235b in step S224. At the start of the suppression control, the control information storage area 235d stores the start time of the suppression control.

  On the other hand, if the second possible amount (P2) <the target level (TL), in step S244, the suppression control is executed under the conditions stored in the second condition storage area 235g. At the start of the suppression control, the start time of the suppression control is stored in the control information storage area 235d.

  Note that steps S225 to S231 and steps S245 to S251 related to the release of the suppression control are the same as steps S116 to S122 and steps S136 to S142 of the first embodiment, respectively, and thus description thereof is omitted.

(4) Features The present embodiment has the same features as the first embodiment except that the unit price of energy is distributed.

(5) Modification The gist of Modification 1A according to the first embodiment and 1C to 1I also applies to the second embodiment. In addition, the 1st energy suppression possible amount and the 2nd energy suppression possible amount of the modified example 1A are read as the first possible amount and the second possible amount, respectively. The term “immediately after receiving the suppression request” in Modification 1G is read as “immediately after reaching the candidate time”.

The information related to the penalty is information related to an extra charge when the energy consumption exceeds the energy suppression request amount during a predetermined period.

  Specifically, the information on incentives was able to continue to suppress power below the required energy suppression amount for a certain period of time while properties A and B were being requested for suppression control from power company 1 to properties A and B. In this case, it is information that the unit price per amount of power of the properties A and B is discounted by 1 yen for the time period. Information on the penalty is the unit price per power amount during the suppression control period when the power exceeds the energy suppression request amount even once during the request for suppression control from the power company 1 to the property A or B. The information is to add 2 yen.

  Note that the above information on incentives and penalties is an example, and the incentives and penalties are not limited to information on discounted charges and premiums. The incentive may be an economic merit that induces the user to reduce power usage, and the penalty may be an economic demerit that suppresses an increase in power usage by the user. Here, the contents of the incentive and penalty are determined in advance by a contract, but the present invention is not limited to this, and the contents may be changed depending on the power supply / demand situation or the like.

In this case, the adjustment control unit 336c is instructed to cancel execution of the suppression control.

  Other points are the same as those of the first release unit 36j of the first embodiment.

(2-2-2-7) Second release portion 336l
The second release unit 336l determines that the actual value has achieved the target level by the actual value determination unit 336i, determines that the predicted actual value has achieved the target level by the predicted actual value determination unit 336n, and When the comfort determination unit 336k determines that the comfort is impaired, the adjustment control unit 336c is instructed to cancel the execution of the suppression control.

(3) About the control process performed with the energy management system 300 Hereinafter, the flow of the process in the control apparatus 330 which controls equipment is demonstrated using FIG. The flowchart showing the flow of presentation of the first energy suppression possible amount in the control device 330 to the management device 310 is the same as in FIG. 9 of the first embodiment in the third embodiment, and the description thereof will be omitted.

  In the present embodiment, it is determined whether the actual value satisfies the target level for the entire equipment, and the execution of the suppression control is released separately for the air conditioners 40, 40... And other equipment. Is going. However, for each type of equipment, for each equipment location, and for each equipment, the actual value is grasped, the predicted actual value is predicted, and the achievement level of the target level is judged. The suppression control may be released for each location and for each facility device. Moreover, suppression control may be cancelled | released by either the 1st or 2nd cancellation | release part 336j, 336l about all the installation apparatuses.

  In step S411, the communication unit 331 receives an energy consumption suppression request from the management device 310 together with information on the energy suppression request amount, the suppression request time, the incentive and the penalty, and stores the request in the request storage area 335c. The timing of the suppression request is irregular.

  In step S412, the determination unit 336g determines a calculation condition for the first energy suppression possible amount corresponding to the distributed energy suppression request amount based on the energy suppression request amount and suppression request time distributed from the management device 310.

  In step S413, the recalculation unit 336h calculates the second energy suppression possible amount (PE2 in FIG. 22a) under the same conditions as those determined in step S412.

  In step S414, the second energy suppression possible amount (PE2) is compared with the energy suppression request amount (D in FIG. 22a) stored in the request storage area 335c.

  If the result of step S414 is the second energy suppression possible amount (PE2) ≦ the energy suppression required amount (D), the process proceeds to step S415, and the suppression control is performed using the conditions used for calculating the second energy suppression possible amount. Be started. At this time, the start time of the suppression control is stored in the control information storage area 335d.

  In step S416, the actual energy grasping unit 336f grasps the reduced energy price (actual value). The actual value grasped by the achievement grasping unit 336f is stored in the control information storage area 335d.

  In step S417, it is determined whether or not the actual value stored in the control information storage area 335d has reached the target level stored in the target storage area 335g.

  When it is determined in step S417 that the target level has been achieved, prediction by the second prediction unit 336m is started in step S420.

  If it is determined in step S417 that the actual value has not reached the target level, the process proceeds to step S418. In step S418, it is determined whether the suppression request time has ended. If it is determined that the request time has ended, the execution of the suppression control is ended. If it is determined that the request time has not ended, the process returns to step S416. Steps S416 and S417 are repeatedly executed every predetermined period (in this embodiment, every 5 minutes) until it is determined in step S418 that the suppression request time has ended.

  In step S420, the second prediction unit 336m calculates, as a predicted actual value, an energy price that is predicted to be reduced at the end of the suppression request time when the suppression control is immediately canceled.

  In step S421, the predicted actual value is predicted to be reduced when the suppression request time elapses when the predicted actual value determination unit 336n satisfies the target level, that is, when the suppression control is immediately canceled. It is determined whether or not becomes equal to or higher than the target level. If it is determined in step S421 that the predicted performance value has reached the target level, the process proceeds to step S422. If it is determined in step S421 that the predicted performance value has not reached the target level, the process proceeds to step S426.

  Since the process from step S422 to step S425 is the same as the process from step S119 to step S122 of the first embodiment, the description thereof is omitted.

  In step S426, it is determined whether the suppression control is relaxed. If the suppression control is not relaxed, the process proceeds to step S427. If the suppression control is relaxed, the process proceeds to step S428.

  In step S427, the mitigation unit 336o commands the adjustment control unit 336c to mitigate the execution of the suppression control for all the equipment devices. The adjustment control unit 336c starts executing suppression control using the conditions of the relaxation condition storage area 335l.

  In step S428, it is determined whether the suppression request time has ended. If it is determined that the request time has ended, the execution of the suppression control is ended. If it is determined that the requested time has not ended, the process returns to step S420.

  On the other hand, when the second energy suppression possible amount (PE2)> the energy suppression required amount (D), suppression control is started using the condition of the second condition storage area 335f in step S435. In step S435, the start time of the suppression control is stored in the control information storage area 335d. Thereafter, the process proceeds to step S436.

  Step S436 to step S438, step S440 to step S445, step S446, and step S448 are the same as step S416 to step S418, step S420 to step S425, step S426, and step S428, respectively, and thus description thereof is omitted.

  In the relaxation of the suppression control in step S447, the relaxation unit 336o commands the adjustment control unit 336c to relax the execution of the suppression control for all equipment devices, and the adjustment control unit 336c sets the conditions of the first condition storage area 335b. The execution of the used suppression control is started. Thereafter, the process proceeds to step S462.

(4) Features The control device 330 according to the third embodiment has the following features in addition to the features according to the first embodiment.

(4-1)
The control device 330 for controlling the equipment (air conditioners 40, 40,..., Lighting 50, 50,..., Ventilation fans 60, 60,...) According to the present embodiment is the second prediction unit 336m. And a predicted performance value determination unit 336n. The second prediction unit 336m predicts the transition of power during the second predetermined period (from the time of prediction by the second prediction unit 336m to the end of the suppression request time). Further, the second prediction unit 336m predicts a predicted actual value (energy price predicted to be reduced at the end of the suppression request time) after the second predetermined period as a predicted actual value based on the predicted power transition. To do. That is, the second prediction unit 336m functions as an energy consumption prediction unit and an actual value prediction unit. The predicted actual value determination unit 336n determines whether the predicted actual value satisfies the target level set for the actual value. The first canceling unit 336j cancels the execution of the suppression control based on the determination result of the actual value determining unit 336i and the determination result of the predicted actual value determining unit 336n.

  As a result, the execution of the suppression control is canceled in consideration of the predicted actual value after the elapse of the second predetermined period, so even if the actual value has once reached the target level, the second predetermined is achieved by canceling the suppression control. It is possible to prevent the actual value from reaching the target level after the period has elapsed.

(4-2)
The control device 330 that controls facility equipment according to the present embodiment further includes a relaxation unit 336o. The relaxation unit 336o relaxes the suppression control based on the determination result of the predicted actual value determination unit 336n. The relaxation unit 336o relaxes the suppression control based on the determination result of the actual value determination unit 336i when the execution of the suppression control is not canceled by the first cancellation unit 336j.

  Here, since the suppression control is relaxed even when the execution of the suppression control is not cancelled, the user's comfort is easily improved. Further, since the execution of the suppression control is not canceled, it is easy to prevent the actual value from reaching the target level after a predetermined period.

(5) Modifications The gist of Modification Examples 1A to 1C and 1F to 1J according to the first embodiment also applies to the third embodiment. Moreover, the modification in 3rd Embodiment is shown below.

(5-1) Modification 3A
In the present embodiment, even if the actual value reaches the target level, if the predicted actual value does not reach the target level, the suppression control is relaxed. However, the control device 330 is not limited to this. As shown in FIG. 23, a delay unit 336p may be provided instead of the mitigation unit 336o, and execution of suppression control may be delayed.

  For example, the delay unit 336p delays a command for canceling execution of suppression control for the adjustment control unit 336c of the first cancellation unit 336j by a predetermined time. At this time, the delay time may be different depending on the type of equipment. Moreover, if the delay part 336p cancels | releases suppression control, in order to ensure a user's comfort, about the equipment which may increase the usage-amount of electric power rapidly, for example, about air conditioners 40, 40 ... Takes a long time to delay, and if it arrives at other equipment, the delay time may be shortened or zero.

  Further, the delay unit 336p may delay the time when the first canceling unit 336j commands the adjustment control unit 336c to cancel the execution of the suppression control based on the relationship with the target level with the predicted actual value. More specifically, the delay unit 336p delays execution of the suppression control until the actual value reaches the target level and the predicted actual value reaches the target level.

  Here, because the execution of suppression control is delayed taking into account the predicted actual value, the actual value does not reach the target level after a predetermined period of time compared to when the suppression control is canceled based on the current actual value alone. Easy to prevent from becoming.

(5-2) Modification 3B
In the present embodiment, when the actual value reaches the target level and the predicted actual value does not reach the target level, the suppression control is relaxed, but the present invention is not limited to this.

  For example, the relaxation unit 336o may not relax the suppression control until it is determined that the predicted performance value reaches the target level even if the suppression control is relaxed.

  In this case, the target level is surely easily achieved.

(5-3) Modification 3C
In this embodiment, when the actual value reaches the target level and the predicted actual value does not reach the target level, the suppression control is relaxed only in one stage, but the present invention is not limited to this.

  For example, the storage unit 335 may store conditions for mitigating multistage suppression control, and the suppression control may be relaxed in multiple stages. When mitigating suppression control in multiple stages, the stage of relaxation of suppression control may be changed depending on the elapsed time, and the stage of relaxation of suppression control is changed based on the difference between the predicted actual value and the target level. May be.

  By relaxing the suppression control in multiple stages, the user's comfort and the achievement of the target level are easily executed with high accuracy.

(5-4) Modification 3D
In the present embodiment, when the actual value reaches the target level and the predicted actual value does not reach the target level, the suppression control is relaxed for all the facility devices, but the present invention is not limited to this.

  For example, if the mitigation unit 336o cancels the suppression control, the equipment that may suddenly increase the amount of power used to ensure the user's comfort, such as the air conditioners 40, 40. Only the suppression control may be relaxed. For other equipment, execution of suppression control may be canceled when the actual value reaches the target level.

  Thereby, it becomes easy to achieve the target level of the actual value while ensuring the user's comfort.

JP 2005-107901 A JP 2004-116820 A

  The present invention relates to a control device for equipment.

  In recent years, there has been a widespread movement in which energy suppliers work on a plurality of properties that are users to control energy consumption during times of high energy demand and to efficiently operate energy supply facilities.

  For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2005-107901), a power supplier monitors the usage status of a user's electrical equipment, and when the power supply and demand is tight, the needs of the power supplier and the user's predetermined electricity A system has been proposed in which a user's electrical device is stopped based on a priority order regarding the stop of the device.

  Note that when the energy consumption of the property is controlled, the user's comfort is likely to be impaired, and thus it is necessary to consider the user's comfort. For example, in Patent Document 2 (Japanese Patent Application Laid-Open No. 2004-116820), when energy saving control of equipment is performed, if it is determined that the user's comfort is impaired, the control considering the comfort from the energy saving control is performed. A system that can be switched to is proposed.

  However, when the energy suppression control is canceled according to the user's comfort as in Patent Document 2, the energy consumption may not be sufficiently suppressed. If energy consumption is not sufficiently controlled, the user will suffer the disadvantage of increased energy prices, and depending on the contract with the energy supplier, the penalty may be paid as a penalty for not being able to sufficiently suppress energy consumption. There is a possibility that obligations may arise.

  The subject of this invention is providing the control apparatus of the equipment which can aim at the achievement of the target of energy consumption suppression, and a user's comfort, when a property receives the suppression request | requirement of energy from an energy supplier. is there.

A control device according to a first aspect of the present invention is a control device that controls equipment, and includes a reception unit, a control unit, a grasping unit, a performance value determination unit, and a first release unit. The reception unit receives an energy suppression request or energy unit price distribution from a management device of an energy supplier that supplies energy to the equipment. A control part performs suppression control of energy consumption according to the suppression request | requirement or unit price delivery. The grasping unit grasps the reduced energy price during the first predetermined period as the actual value of the suppression control. Actual value determination unit determines the actual value, which satisfies the target level when exceeds a predetermined value. A 1st cancellation | release part cancels | releases execution of suppression control based on the determination result of a performance value determination part.

Here, the reduced energy price is grasped as the actual value of the energy suppression control, and the execution of the energy suppression control is canceled on the condition that the actual value satisfies the target level. If the actual value does not satisfy the target level, the execution of the suppression control is not canceled, so it is easy to achieve both comfort and energy suppression.

By using the reduced energy price as the actual value, the user can easily feel the result of the energy suppression control, and can induce further energy suppression of the user.

The control device according to the second aspect of the present invention is the control device according to the first aspect, and further includes a storage unit. The storage unit stores information on at least one of incentives and penalties for suppressing energy consumption. The grasping unit grasps the reduced energy price using the information.

A control device according to a third aspect of the present invention is a control device that controls equipment, and includes a reception unit, a control unit, a grasping unit, a performance value determination unit, an energy consumption prediction unit, and a performance value. A prediction unit, a predicted performance value determination unit, a first release unit, and a mitigation unit are provided. The reception unit receives an energy suppression request or energy unit price distribution from a management device of an energy supplier that supplies energy to the equipment. A control part performs suppression control of energy consumption according to the suppression request | requirement or unit price delivery. The grasping unit grasps one or more result values as the results of the suppression control. The actual value determination unit determines whether a part or all of the actual values satisfy a target level set for each actual value. The energy consumption amount prediction unit predicts the transition of the energy consumption amount during the first predetermined period.

In this embodiment, for example, as shown in FIG. 4, a plurality of combinations of the control time length and the energy consumption reduction rate are stored as conditions.

  First, the calculation unit 36d calls the electric power [kW] immediately before the calculation of the first energy suppression possible amount from the driving situation storage area 35a. At the same time, the calculation unit 36d calls the conditions stored in the first condition storage area 35b. Thereafter, the calculation unit 36d calculates the first energy suppression possible amount PE1 for each condition. The first energy suppression possible amount PE1 is represented by the following equation.

  (Formula 1) PE1 = p × (1-k)

  Here, p represents the power [kW] immediately before the calculation of the first energy suppression possible amount, and k represents the energy consumption reduction rate [%]. Note that the predicted power stored in the predicted amount storage area 35e may be used for p instead of the power immediately before the calculation of the first energy suppression possible amount.

  A case where the electric power immediately before the calculation of the first energy suppression possible amount is used for calculation of the first energy suppression possible amount PE1 will be described with a specific example.

  For example, it is assumed that the electric power immediately before the first energy suppression possible amount calculation called from the driving situation storage area 35a is 100 kW, and FIG. 4 is stored in the first condition storage area 35b. At this time, the first energy suppression possible amount PE1 is calculated as 80 kW, 90 kW, and 95 kW for the control time of 30 minutes, 60 minutes, and 120 minutes, respectively.

  PE1 may be weighted as in the following equation.

  (Formula 2) PE1 = p * (1-k) * m1 * m2 * ... * mN

  Here, m1, m2,..., MN are, for example, the time when the suppression control is performed, the predicted power, the predicted power amount, the predicted energy price, the state value of the indoor environment, the environmental condition, the operating state of the equipment, and It is a weighting coefficient related to the achievement status of the actual value grasped by the achievement grasping unit 36f with respect to the target level. The number of weighting factors may be one or plural.

  The condition may relate to a suppression control method. In this case, the first energy suppression possible amount is calculated as follows, for example.

  The calculation unit 36d calls the control method stored in the first condition storage area 35b of the facility device as a condition, and calculates a first energy suppression possible amount that can be minimized. For example, the first energy suppression possible amount PE1 can be expressed by Equation 3.

  (Formula 3) PE1 = Max (a1t * R1 + a2t * R2 + ... + aXt * RX)

  Here, R1, R2,... RX is the rated capacity [kW] of each of the X equipment. a1t, a2t,... aXt are determined by the On / Off of the equipment in a certain time zone t in the time zone for which the first energy suppression possible amount is calculated. Defined as 0.

  Specifically, the case where the control schedule of FIG. 5 is stored as a condition in the first condition storage area 35b will be described as an example.

  In FIG. 5, there are four time zones every 15 minutes. When (a1 × R1 + a2 × R2 +... + A7 × R7) is calculated for each time zone, they are 70 kW, 80 kW, 75 kW, and 75 kW. Among these, since the maximum value is 80 kW, the first energy suppression possible amount PE1 is calculated as 80 kW.

  Note that Expression 3 may be weighted in the same manner as Expression 2. Description is omitted.

(2-2-6-5) Presentation unit 36e
The presentation unit 36e presents the management device 10 with one or more first energy suppression possible amounts calculated by the calculation unit 36d and stored in the transmission storage area 35h together with the suppression possible time.

(2-2-6-6) Results grasping part 36f
The result grasping part 36f grasps the result of energy suppression control as a result value. The actual value is, for example, a reduced energy amount, a reduced energy price, or an accumulated time of executed suppression control. In addition, although the track record value grasped | ascertained is one in this embodiment, multiple may be sufficient. The target storage area 35g stores a target level corresponding to the amount grasped by the record grasping unit 36f. Information grasped by the record grasping unit 36f is stored in the control information storage area 35d.

  In the present embodiment, the actual value is grasped for the entire equipment, but the actual value may be grasped for each group of equipment. For example, the actual value may be grasped according to the type of equipment or the installation floor of equipment. The group may be set freely by the user by inputting from the input unit 33. Based on the information in the operating status storage area 35a, the equipment may be grouped according to the operating status of the equipment, for example, the operating frequency. When grasping the actual value for each group, the target level stored in the target storage area 35g may also be set for each group.

  Furthermore, a performance value may be grasped | ascertained with respect to each installation apparatus, and the target level memorize | stored in the target storage area 35g may be set for every installation apparatus.

(2-2-6-7) Discriminator 36g
The determination unit 36g determines a condition when the first energy suppression possible amount corresponding to the energy suppression request amount distributed from the management device 10 is calculated. Specifically, the distributed information is compared with the information stored in the transmission storage area 35h, and the corresponding calculation condition is determined.

(2-2-6-8) Recalculation unit 36h
The recalculation unit 36h calculates the second energy suppression possible amount under the same conditions as those determined by the determination unit 36g. Note that the same condition as the condition determined by the determination unit 36g is a condition in which the condition at the time of calculating the second possible energy suppression amount is reflected in the condition at the time of calculating the first possible amount corresponding to the required energy suppression amount. Therefore, both conditions may not match.

  Specific examples will be described.

  For example, it is assumed that the conditions relating to the energy consumption suppression rate of FIG. 8 are stored in the first condition storage area 35b, and the outside air temperature was 35 ° C. when calculating the first energy suppression possible amount. In this case, at the time of calculating the first energy suppression possible amount, the suppression rate of the energy consumption with respect to each control time is 20%, 10%, and 5%. On the other hand, for example, it is assumed that the outside temperature at the time of calculating the second energy suppression possible amount is 40 ° C. In this case, the suppression rate of energy consumption is 16%, 8%, and 4% for each control time.

  Therefore, when the management apparatus 10 selects the first energy suppression possible amount corresponding to the control time of 60 minutes as the energy suppression request amount for the presentation of the first energy suppression possible amount, the energy consumption is calculated when calculating the first energy suppression possible amount. Although the amount suppression rate is 10%, it is 8% when calculating the second energy suppression possible amount.

  In addition, the calculation method itself of the 2nd energy suppression possible amount is the same as that of the calculation part 36d.

  For example, when the condition is an energy consumption suppression rate, the second energy suppressible amount PE2 is calculated by the following Expression 4 or Expression 5.

(Formula 4) PE2 = p ′ × (1−k ′)
(Formula 5) PE2 = p ′ × (1−k ′) × m1 ′ × m2 ′... × mN ′

  Here, p ′ is the power [kW] immediately before the second energy suppression possible amount calculation. k 'is the energy consumption suppression rate under the same conditions as those determined by the determination unit 36g. mN ′ is a weighting factor. If the weighting factor mN ′ in Equation 5 varies depending on the state at the time of calculation, the weighting factor mN ′ may also be different from the weighting factor mN at the time of calculating the first energy suppression possible amount.

(2-2-6-9) Actual value determination unit 36i
The actual value determination unit 36i compares the actual value stored in the control information storage area 35d with the target level stored in the target storage area 35g. In addition to determining whether the actual value has achieved the target level, the achievement rate of the actual value with respect to the target level is also calculated.

  In this embodiment, the achievement level target level achievement condition is determined for the entire equipment. However, for example, when the actual value is grasped by the type of equipment or by the installation floor of the equipment, the actual value may be determined by the type of equipment or by the installation floor. . Moreover, you may perform determination of a performance value separately for equipment.

(2-2-6-10) First release unit 36j
The first cancellation unit 36j instructs the adjustment control unit 36c to cancel the execution of the suppression control when the actual value determination unit 36i determines that the actual value has achieved the target level. In this embodiment, equipment other than the air conditioners 40, 40,... Is controlled by the first release unit 36j, but the air conditioners 40, 40,. It may be targeted.

  In this embodiment, the 1st cancellation | release part 36j commands execution cancellation | release of suppression control collectively with respect to installation apparatuses other than air conditioner 40,40, .... However, when the actual value determination unit 36i knows the actual value for each group or for each facility device, the suppression control is performed for each facility device group such as each facility device type or for each facility device. Execution cancellation may be commanded.

(2-2-6-11) Comfort determination unit 36k
The comfort determination unit 36k determines the user comfort based on the driving situation stored in the driving situation storage area 35a. Comfort is determined, for example, by the degree of deviation between the set temperature of the air conditioner and the actual room temperature.

  In this embodiment, only the air conditioners 40, 40,... Are determined as comfort determination targets, but the comfort may be determined for other equipment. In this case, for example, the illumination is 50, 50,..., The illuminance, and the ventilation fans 60, 60,.

  Moreover, in this embodiment, although the comfort is grasped | ascertained as the whole property, for example, it is individual apparatus, for example, air conditioner 40,40, ... separate (indoor unit 42,42, ... separate or outdoor unit 41). , 41,...), Or by equipment equipment group, such as by floor or by operation frequency.

(2-2-6-12) Second release portion 36l
The second release unit 36l adjusts when the actual value determination unit 36i determines that the actual value has achieved the target level, and the comfort determination unit 36k determines that the comfort is impaired. The control unit 36c is instructed to cancel execution of the suppression control. In this embodiment, only the air conditioners 40, 40,... Are controlled by the second release unit 36l, but other equipment may also be controlled by the second release unit 36l.

  In the present embodiment, the second release unit 36l collectively commands the release of the suppression control of the air conditioners 40, 40,... For the entire property, but for example, for each device (for example, the air conditioners 40, 40,...・ Order to cancel execution of suppression control separately (for indoor units 42, 42,... Or for outdoor units 41, 41,...) May be.

(3) Control Process Performed by Energy Management System 100 FIG. 9 is a flowchart showing a flow of presentation of the first energy suppression possible amount to the management apparatus 10 mainly in the control apparatus 30. FIGS. 10 a and 10 b are flowcharts showing the flow of suppression control processing in the control device 30. The processes shown in FIGS. 9 and 10a and 10b are independent of each other. Hereinafter, the flow of processing in the control device 30 that controls equipment is described with reference to FIGS. 9 and 10a and 10b.

  First, FIG. 9 will be described.

  In this embodiment, step S101 is performed every day at 10 am. In step S101, the first energy suppression possible amount is calculated by the calculation unit 36d based on the power immediately before 10:00 am and the condition stored in the first condition storage area 35b. The calculated first energy suppression possible amount is stored in the transmission storage area 35h. Note that the predicted power calculated in step S103 may be used to calculate the first energy suppression possible amount, but in this case, step S103 is executed first, and the start time of step S101 is the same as that of step S103. After the end (for example, 10:10 am).

  In step S102, the presentation unit 36e calls the first energy suppression possible amount from the transmission storage area 35h and presents it to the management device 10.

  In step S103, after 10:00 am (10:05 am in the present embodiment), the prediction unit 36b calls information from 10:00 am on the previous day to 10:00 am on the current day from the driving state storage area 35a, Predict power, amount of electricity and energy price from 10:00 to 10:00 am the next day. The predicted amount is stored in the predicted amount storage area 35e.

  If it is determined in step S104 that it is 10 am, step S101 is executed again.

  On the other hand, even if it is not 10:00 am, if it is determined in step S105 that the management device 10 has requested transmission of the first energy suppression possible amount, the first energy suppression possible amount is calculated in step S106 and transmitted. It is stored in the storage area 35h. Thereafter, in step S107, the presentation unit 36e presents the first energy suppression possible amount to the management device 10.

  When there is no transmission request, it waits until 10:00.

  Next, FIGS. 10a and 10b will be described.

  In step S111, the communication unit 31 receives an energy consumption suppression request from the management device 10 together with the energy suppression request amount, and stores the request in the request storage area 35c. The timing of the suppression request is irregular.

  In step S112, based on the information distributed from the management apparatus 10, the determination unit 36g determines a calculation condition for the first energy suppression possible amount corresponding to the distributed energy suppression request amount.

  In step S113, the recalculation unit 36h calculates the second energy suppression possible amount (PE2 in FIG. 10a) under the same conditions as those determined in step S112.

  In step S114, the second energy suppression possible amount (PE2) is compared with the energy suppression request amount (D in FIG. 10a) stored in the request storage area 35c.

  If the result of step S114 is the second energy suppression possible amount (PE2) ≦ the energy suppression required amount (D), the suppression control starts using the conditions used for calculating the second energy suppression possible amount in step S115. Is done. At this time, the start time of the suppression control is stored in the control information storage area 35d. During the suppression control, the record value is grasped by the record grasping unit 36f in step S116. The record value grasped by the record grasping part 36f is stored in the control information storage area 35d. In step S117, it is determined whether the actual value has achieved the target level stored in the target storage area 35g. Step S116 and step S117 are repeatedly executed every predetermined period (every 5 minutes in the present embodiment) until it is determined in step S118 that the suppression request time has ended. If it is determined in step S117 that the target level has been achieved, in step S119, the first release unit 36j orders the release of the suppression control for equipment other than the air conditioners 40, 40,. (First release). The time when the first release is executed is stored in the control information storage area 35d. If the actual value has achieved the target level, the comfort determination unit 36k determines comfort in step S120. Step S120 is repeatedly executed until it is determined in step S121 that the suppression request time has ended. If it is determined that the comfort is not satisfied, in step S122, the second release unit 36l commands release of the suppression control of the air conditioners 40, 40,. At the end of the suppression control, the time when the suppression control is released and the amount of power reduced through the suppression control are stored in the control information storage area 35d.

  In addition, for example, for each type of equipment, for each equipment location, and for each equipment, the actual value is ascertained and the achievement level of the target level is determined, and each equipment type, equipment location, and equipment When canceling the suppression control for each device, a plurality of steps S116 to S122 are performed as shown in FIG. In this case, when there is only an equipment device whose execution of suppression control is canceled by the first cancellation, steps S120 to S122 are not necessary. Step S119 is unnecessary when there is only an equipment device whose suppression control is canceled by the second cancellation.

  On the other hand, when the second energy suppression possible amount (PE2)> the energy suppression required amount (D), suppression control is started using the condition of the second condition storage area 35f in step S135. In step S135, the start time of the suppression control is stored in the control information storage area 35d. Steps S136 to S142 are the same as steps S116 to S122, respectively, and a description thereof will be omitted.

(4) Features (4-1)
In this embodiment, the control device 30 controls the equipment (air conditioners 40, 40,..., Lighting 50, 50,..., Ventilation fans 60, 60,...) The adjustment control unit 36c, the actual result grasping unit 36f, the actual result value determining unit 36i, and the first release unit 36j are provided. The communication unit 31 receives an energy suppression request from the management device 10 of the energy supplier that supplies energy to the equipment. The adjustment control unit 36c performs energy consumption suppression control in response to the suppression request. The result grasping unit 36f grasps one or a plurality of result values as the results of the suppression control. The actual value determination unit 36i determines whether a part or all of the actual values satisfy a target level set for each actual value. The first canceling unit 36j cancels the execution of the suppression control based on the determination result of the actual value determining unit 36i.

  The actual value of the energy suppression control is grasped, and the energy suppression control is canceled on the condition that the actual value satisfies the target level. Since the suppression control is not released unless the actual value satisfies the target level, it is easy to achieve both the comfort and achievement of the energy suppression control.

(4-2)
In the present embodiment, as the actual value of the energy suppression control, for example, a reduced energy amount, a reduced energy price, or an integrated time of suppression control during a predetermined period is used. The actual value determination unit 36i determines that the actual value has satisfied the target level when the actual value exceeds the value set as the target level.

  Setting the target level for the reduced energy amount, the reduced energy price, or the integration time of the suppression control makes it easier for the user to realize the results of the energy suppression control. If the user can realize the result, it is expected that further energy suppression control can be attracted.

(4-3)
The record grasping unit 36f may grasp record values individually for each equipment and / or for each group. At this time, the actual value determination unit 36i determines whether the actual value satisfies the target level for each equipment and / or for each group. The 1st cancellation | release part 36j cancels | releases execution of suppression control for every installation apparatus and / or for every group.

  Since it is possible to judge whether the actual value has reached the target level for each equipment and / or group, and the restraint control can be released for each equipment and / or group, highly flexible restraint control is realized. Cheap.

(4-4)
In this embodiment, the comfort determination part 36k and the 2nd cancellation | release part 36l are further provided. The comfort determination unit 36k determines user comfort. In addition to the determination result of the actual value determination unit 36i, the second release unit 36l performs suppression control on all or part of the equipment when the comfort determination unit 36k determines that the comfort is not satisfied. Cancel execution.

  Here, in addition to the achievement value achieving the target level, the execution of the energy suppression control is canceled only when it is determined that the user's comfort is not satisfied. If the user's comfort is satisfied, the suppression control is not canceled as much as possible, and the achievement value is further increased.

(4-5)
In particular, the comfort determination unit 36k determines comfort related to air conditioning. The second release unit 36l that uses the achievement of the target level of the actual value and the loss of comfort as the release condition of the suppression control is used only to cancel the execution of the suppression control of the air conditioners 40, 40,. . On the other hand, the 1st cancellation | release part 36j which makes a cancellation | release condition only achievement of the target level of a performance value is used for cancellation | release of execution of suppression control of equipment other than air conditioner 40,40, ....

  Among the equipment, air conditioning units 40, 40,... That have a relatively large impact on user comfort can be released from the two aspects of achievement of the target level of the actual value and ensuring of comfort. It is determined.

(5) Modification (5-1) Modification 1A
The calculation unit 36d and the recalculation unit 36h use the formula 1, the formula 2, the formula 4 or the formula 5 to calculate the first energy suppression possible amount or the second energy suppression possible amount to the power (kW) immediately before the calculation. Instead, for example, an average value of the electric energy per unit time for 30 minutes immediately before the calculation may be used. By referring to the driving situation for a certain period, it is possible to calculate an energy suppression possible amount that is closer to the actual value.

(5-2) Modification 1B
The control device 30 may not include the presentation unit 36e. In this case, the suppression request amount is distributed according to a contract determined between the power company and the contract between the power company and the user. The suppression control in this case is executed as follows, for example.

  The calculation unit 36d calculates the first energy suppression possible amount and compares it with the presented energy suppression request amount. Then, the calculation unit 36d finds a condition in which the first energy suppression possible amount> the energy suppression request amount can be satisfied from the first condition storage area 35b. The adjustment control unit 36c performs suppression control using the found condition. About cancellation | release of suppression control, it is the same as that of 1st Embodiment. In this case, the determination unit 36g and the recalculation unit 36h are also unnecessary.

(5-3) Modification 1C
The adjustment control unit 36c may not execute the suppression control when there is a possibility that the comfort cannot be ensured by executing the suppression control. For example, if the measured values of temperature and humidity have not reached the set values and are deviating more than predetermined, even though they are currently operating at a driving capacity of 100%, the suppression control is performed. It is not necessary to execute. In addition, for example, the control command may not be executed for a certain period of time after the start of operation.

(5-4) Modification 1D
When the actual value grasped by the actual result grasping part 36f is the reduced energy price, the calculation of the actual value is subject to a penalty or additional charge when the property fails to achieve the energy suppression requirement amount presented by the electric power company. Penalties may be considered.

  In addition, when the actual value grasped by the actual result grasping unit 36f is a reduced energy amount, when the energy amount is increased more than usual during the suppression control, the increase value is considered in calculating the actual value. Good.

  Specifically, for example, when using a reduced energy price as the actual value, the actual value is obtained by subtracting the amount to be paid as a penalty from the energy price that could be reduced by restraint control, and comparing that value with the target level. Also good.

(5-5) Modification 1E
The actual value determination unit 36i may execute the determination by comparing the future predicted actual value and the target level, instead of comparing the actual value to the present and the target level.

  Specifically, for example, using the predicted power predicted by the prediction unit 36b, the predicted power amount, the predicted energy price, and the like, the actual value is at the end time of the suppression control distributed by the management apparatus 10 of the power company. Determine whether the target level can be achieved.

  In this case, for example, even if the target level is achieved at the present time, if it is determined that the target level will not be achieved at the end time of the suppression control if the suppression control is canceled, the first cancellation unit 36j cancels the execution of the suppression control. Do not order.

(5-6) Modification 1F
The first release unit 36j and the second release unit 36l do not have to execute a command to release the suppression control when the remaining time of the suppression control is equal to or less than a predetermined value.

  Since recovery of comfort is expected after the suppression control is completed, if the remaining time is short, the accumulation of the actual value is given priority.

(5-7) Modification 1G
The adjustment control unit 36c may execute strong suppression control for ensuring responsiveness for a short period of time immediately after receiving a request, instead of executing uniform suppression control. Once the responsiveness is ensured, the suppression control that achieves both energy reduction and user comfort as described in the first embodiment is executed.

(5-8) Modification 1H
The user may be able to manually cancel the suppression control. However, also in this case, during the suppression control, the remaining time of the suppression control (end time of the suppression request time) and the actual value that can be achieved with the remaining time of the suppression control are output to the output unit 32. The current situation can be accurately grasped, and the suppression control is not easily released.

(5-9) Modification 1I
In the present embodiment, the first release unit 36j and the second release unit 36l are configured so that the actual value reaches the target level (if the second release unit 36l determines that the user's comfort is not satisfied). The execution of the suppression control is released, but in addition to this, a time period during which the execution of the suppression control cannot be released may be determined.

  Specifically, during the time period determined by the prior agreement between the power company 1 and the property A, for example, from 12:00 to 19:00, the first release unit 36j and the first Even if the execution cancellation condition of the suppression control of the 2 cancellation unit 36l is satisfied, the suppression control execution is not canceled.

  Thereby, the electric power company 1 can request not to cancel the execution of the suppression control in a time zone in which the power supply and demand is particularly severe, and can prevent a shortage of supplied power.

(5-10) Modification 1J
In the present embodiment, the first release unit 36j and the second release unit 36l release the execution of the suppression control when the condition is satisfied, but is not limited to this. For example, instead of releasing the suppression control The content of the suppression control may be changed.

  A specific example will be described.

  When the power company 1 requests the property A to perform suppression control, the power company 1 transmits the required suppression energy amount together with the suppression request energy amount. The amount of energy that must be suppressed is the amount of energy that the power company 1 requests the property A to reliably achieve. That is, the amount of energy required to be suppressed is an amount that the property A should always achieve in principle, while the amount of energy required for suppression has the meaning of a recommended value. If the 1st cancellation | release part 36j and the 2nd cancellation | release part 36l satisfy | fill the conditions shown in this embodiment, instead of suppressing an energy consumption to the suppression request | requirement energy amount, the suppression which suppresses an energy consumption to a required suppression energy amount Execute control.

  More specifically, it is assumed that the electric power company 1 transmits 80 kW as the required suppression energy amount and 90 kW as the required suppression energy amount when requesting the power suppression control for the property A that uses the maximum power of 100 kW. The property A first executes control for suppressing power to 80 kW, which is the required energy amount for suppression. After that, when the first release unit 36j and the second release unit 36l satisfy the conditions, suppression control that allows the power that has been reduced to 80 kW to be increased to 90 kW, which is a necessary suppression energy amount, is executed. In other words, the 1st cancellation | release part 36j and the 2nd cancellation | release part 36l change the content of suppression control instead of canceling execution of suppression control.

  Thereby, in the property A, since the actual value has reached the target level, it is possible to prevent a shortage of power supplied by the power company 1 even when the user's comfort is restored.

Second Embodiment
Next, an energy management system 200 according to the second embodiment will be described (see FIG. 12). Only differences from the first embodiment will be described below.

(1) Overall Configuration of Energy Management System 200 FIG. 12 shows an energy management system 200 according to the present embodiment. In the energy management system 200, power is supplied from S and T as the power companies 1 and 1 to A and B as the properties 2 and 2. Although two electric power companies, S and T, are illustrated, the number of electric power companies is not limited to two. The number of electric power companies may be more than two or one. The properties A and B are the same as in the first embodiment. The system configuration is the same except for the management devices 210 and 210 and the control devices 230 and 230.

  In the second embodiment, the management devices 210 and 210 of the power companies S and T are connected to the control devices 230 and 230 of the property A and B via the Internet 80a at predetermined time intervals (in this embodiment, one day). At intervals, energy unit price information is transmitted. For example, the management devices 210 and 210 distribute unit price information from 9:00 am on that day to 9:00 am on the next day at 7:00 am. The unit price information is information indicating an energy unit price for each time zone. The energy unit price varies depending on the time zone, and is usually determined by the electric power companies S and T so that the energy unit price is high when the energy demand is high and the energy unit price is low when the energy demand is low. The electric power companies S and T do not force the adjustment of energy consumption for the properties A and B by distributing the unit price information. However, the distribution of unit price information is a kind of energy suppression request because the properties A and B are motivated to adjust energy consumption.

(2) Configuration of Each Device Hereinafter, the management devices 210 and 210 and the control devices 230 and 230 included in the energy management system 200 will be described.

(2-1) Configuration of Management Device 210 FIG. 13 shows a schematic configuration diagram of the management device 210. Hereinafter, although the management apparatus 210 installed in the electric power company S is demonstrated, the management apparatus 210 installed in the electric power company T is also the same structure.

  The management device 210 includes a communication unit 211, a display unit 212, an input unit 213, a storage unit 214, and a control unit 215.

(2-2-4-1) Prediction unit 236b
In the present embodiment, for example, the energy consumption is predicted for the energy at 9:05 am. The calculation of the energy price that has been executed in the prediction unit 36b is not executed by the prediction unit 236b. Other points are the same as those of the prediction unit 36b of the first embodiment.

(2-2-4-2) Adjustment control unit 236c
The adjustment control unit 236c executes different suppression control based on the target level stored in the target storage area 235k and the result of the magnitude comparison of the second possible amount described later.

(A) When the second possible amount is equal to or higher than the target level When the second possible amount is equal to or higher than the target level, that is, when the target level is likely to be achieved, the condition stored in the first condition storage area 235b is used. Then, the suppression control is executed.

(B) When the second possible amount is smaller than the target level When the second possible amount is smaller than the target level, that is, when the target level is unlikely to be achieved under the conditions of the first condition storage area 35b, the second condition The suppression control is executed using the conditions stored in the storage area 235g.

(2-2-4-3) Calculation unit 236d
The calculating unit 236d calculates the first possible amount. The first possible amount relates to an amount that is to be grasped as a result of energy suppression control by the result grasping unit 236f described later and the same amount as the target level stored in the target storage area 235k. That is, for example, if the amount and target level to be grasped by the result grasping unit 236f are the amount of energy reduction per suppression control, the first possible amount is also the amount of energy reduction per suppression control [kWh / Times]. In addition, if the amount and target level to be grasped by the result grasping unit 236f are energy reduction prices per one suppression control, the first possible amount is also the energy reduction price per one suppression control [yen / Times].

  In the present embodiment, the amount and the target level that are to be grasped by the achievement grasping unit 236f are energy reduction amounts per one suppression control. The first possible amount P1 is expressed by the following equation, for example. In the present embodiment, the condition of the first condition storage area 235b is a reduction rate of energy consumption, and is determined according to the length of a candidate time zone described later.

  (Formula 6) P1 [kWh / time] = p × k × ΔT

  Here, p is the power [kW] immediately before the first possible amount calculation, k is the energy consumption reduction rate determined by the length of the candidate time zone [%], and ΔT is the length of the candidate time zone [time]. Represents.

  For example, when the target level is a reduction price of energy per one suppression control, the first possible amount P1 is expressed by the following equation, for example.

  (Expression 7) P1 [yen / time] = Σ (p × k × cn × ΔTn)

  Here, cn is the energy unit price [yen / kWh] of the nth time zone when the energy unit price varies according to the time zone in the candidate time zone, and ΔTn is the length of the nth time zone [ Time].

  Note that p may use the predicted power predicted by the prediction unit 236b instead of the power immediately before the calculation of the first possible amount P1.

  The calculated first possible amount is displayed on the output unit 232 so that the user can grasp in advance whether the target level is likely to be achieved. Further, for example, the target level of the actual value stored in the target storage area 235k may be updated using the first possible amount.

  Note that the condition of the first condition storage area 235b used by the calculation unit 236d to calculate the first possible amount is not related to the energy suppression strength, but may be a suppression control method.

(2-2-4-4) Determination unit 236e
The determination unit 236e mainly performs two processes of determining a candidate time zone for which suppression control should be performed and calculating a predicted energy price.

  The candidate time zone is determined as follows.

  The determination unit 236e uses the lowest unit price information created from the unit price information for one or more time zones received by the communication unit 231 to perform suppression control within a predetermined period (one day in the present embodiment). The candidate time zone in which to execute is determined.

  The cheapest unit price information is information that is determined by the determination unit 236e as described below and stored in the lowest unit price storage area 235j.

  When a plurality of unit price information exists in the same time zone, the determination unit 236e compares the energy unit price of each power company and determines the lowest unit price (lowest energy unit price) for each time zone. The determined lowest unit price information for each time zone is stored in the lowest unit price storage area 235j together with the name of the power company providing the lowest unit price as shown in FIG.

  In addition, in the present embodiment, the determination unit 236e determines a time zone in which the energy unit price is maximum from among the lowest unit price information throughout the day as a candidate time zone.

  However, the candidate time zone is not limited to the time zone in which the energy unit price is maximum. For example, the determination unit 236e may select a time zone in which the energy unit price exceeds a predetermined value and determine the candidate time zone. Note that the predetermined value may be a fixed value, or may be a value that is appropriately input by the user from the input unit 233 and updated. The predetermined value may be a value that is appropriately calculated by the determination unit 236e from unit price information such as an average value or an intermediate value of energy unit prices.

  Below, the determination method of a candidate time slot | zone is concretely demonstrated about the case where the time slot | zone where an energy unit price becomes the maximum within a predetermined period as a candidate time slot | zone of this embodiment. Here, a case where there are a plurality of electric power companies will be described.

  First, in the present embodiment, the determination unit 236e reads unit price information of a plurality of energy from 9:00 am on the current day to 9:00 am on the next day, which exists in the unit price storage area 235i, at 9:00 am. And the energy unit price of each electric power company is compared according to a time slot | zone, the cheapest unit price information like FIG. 15 is produced, and it memorize | stores in the cheapest unit price storage area 235j.

  In addition, the determination unit 236e determines, as a candidate time zone, a time zone in which the energy unit price is maximum within a predetermined period, based on information stored in the lowest unit price storage area 235j. For example, in the example of FIG. 15, the determination unit 236e is a time zone in which the energy unit price is the maximum from 13:00 to 16:00 on the current day within a predetermined period (the period from 9:00 am on the current day to 9:00 am on the next day). Determines from 13:00 to 16:00 on that day as a candidate time zone.

  Next, the calculation process of the predicted energy price performed by the determination unit 236e will be described.

  The determination unit 236e calculates a product of the unit price information stored in the cheapest unit price storage area 235j and the amount of power predicted by the prediction unit 236b. As a specific process, the determination unit 236e reads the unit price information stored in the cheapest unit price storage area 235j and the prediction power amount information stored in the prediction amount storage area 235e, and calculates a product by time. . The created information is stored in the predicted price storage area 235f. FIG. 16 is an example of information stored in the predicted price storage area 235f.

  By outputting the predicted energy price calculated in this way to the output unit 232, the user can know the price of energy predicted in advance. Further, the predicted energy price may be used for determining the candidate time zone. For example, in FIG. 16, from 13:00 to 15:00 when the predicted energy price is maximum may be determined as the candidate time zone.

(2-2-4-5) Supply company instruction section 236g
Based on the data stored in the cheapest unit price storage area 235j, the supply company instructing unit 236g gives an instruction to a switchboard (not shown) to purchase power from the cheapest power supply company hourly.

(2-2-4-6) Recalculation unit 236h
The recalculation unit 236h calculates the second possible amount under the conditions stored in the first condition storage area 235b.

  The calculation method is the same as that of the calculation unit 236d.

(3) Control Process Performed by Energy Management System 200 FIG. 17 is a flowchart mainly showing a flow of determination of candidate time zones in the control device 230. 18a and 18b are flowcharts showing the flow of suppression control processing in the control device 230. The processes shown in FIGS. 17 and 18a and 18b are independent of each other. Hereinafter, the flow of processing in the control device 30 for controlling the equipment will be described with reference to FIGS. 17 and 18a and 18b.

  First, FIG. 17 will be described.

  In this embodiment, step S201 is performed every day at 9:00 am. In step S201, the determination unit 236e reads unit price information from 9:00 am on the current day to 9:00 am on the next day from the unit price storage area 235i.

  The unit price information is distributed from the management devices 210 and 210 of one or more power companies S and T to the control device 230 of the property A at a predetermined time interval (one day interval in this embodiment). In the present embodiment, unit price information from 9:00 am on the current day to 9:00 am on the next day is distributed at 7:00 am. The distributed unit price information is stored in the unit price storage area 235i.

  In step S202, the determination part 236e compares the energy unit price of each electric power company according to time slot | zone based on the energy unit price information read by step S201, and determines the cheapest unit price according to time slot | zone. When there is only one electric power company, the distributed unit price information is determined as the lowest unit price information as it is. The lowest unit price for each time zone is stored in the lowest unit price storage area 235j together with the name of the electric power company that presents the lowest unit price.

  In step S203, after 9 am (9:05 am in the present embodiment), the prediction unit 236b reads the past energy consumption from the operating state storage area 235a, and for a predetermined period (9 am on the current day in the present embodiment). Time-by-hour power and power amount prediction from the hour to the next day at 9:00 am is executed. The predicted power and power amount are stored in the predicted amount storage area 235e.

  In step S204, the determination unit 236e uses the information on the cheapest unit price information in the lowest unit price storage area 235j and the predicted power amount in the predicted amount storage area 235e to calculate the product of the unit price for each hour and the predicted energy consumption. Ask for. As a result, for example, a table of predicted energy prices for each hour as shown in FIG. 16 is created. A table of predicted energy prices is stored in the predicted price storage area 235f.

  In step S205, the determination unit 236e determines a candidate time zone in which the energy unit price is the maximum in the predetermined period from 9 am on the current day to 9 am on the next day. For the determination, the cheapest unit price information stored in the cheapest unit price storage area 235j is used. The candidate time zone is not limited to one within the predetermined period. The start time and end time of the determined candidate time zone are stored in the candidate time zone storage area 235h. Instead of the energy unit price, the predicted energy amount stored in the predicted amount storage area 235e or the predicted energy price stored in the predicted price storage area 235f may be used for determining the candidate time zone.

  In step S206, the calculation unit 236d calculates the first possible amount using the power just before the calculation stored in the driving situation storage area 35a and the condition called from the first condition storage area 235b. The calculated first possible amount is output to the output unit 232. For the calculation of the first possible amount, for example, the predicted power calculated by the prediction unit 236b in the candidate time zone determined in step S205 may be used instead of the power immediately before the calculation.

  In addition, the user can grasp | ascertain an indication whether the performance value of energy suppression control is likely to achieve the target level based on the output of the first possible amount. If the target level can be updated, the target level may be updated with reference to the output.

  In step S207, the time of the time management unit 234 is used to determine whether the time has reached 9:00 am. When the time is 9:00 am, step S201 is executed, and the process waits until then.

  However, if the communication unit 231 determines that an urgent change in energy unit price has been received in step S208, in steps S209, S210, S211, S212, and S213, steps S201, S202, S204, and S205, respectively. And the operation of S206 is executed. In steps S209 to S213, the time from the emergency unit price delivery reception time to 9:00 am the next time is set as the candidate time zone determination target.

  Next, FIGS. 18a and 18b will be described.

  In step S221, the recalculation unit 236h uses the current time of the time management unit 234 and the information stored in the candidate time zone storage area 235h to reach the start time of the candidate time zone within 5 minutes. Determine.

  In step S222, the recalculation unit 236h calculates the second possible amount (P2 in FIG. 18a) with reference to the driving situation storage area 235a and the first condition storage area 235b. Note that, for the calculation of the second possible amount, for example, the predicted power calculated by the prediction unit 236b may be used instead of the power immediately before the calculation.

  In step S223, the target level (TL in FIG. 18a) stored in the target storage area 235k is compared with the second possible amount (P2) calculated by the recalculation unit 236h, and the content of the suppression control of the adjustment control unit 236c is determined. decide.

  If the result of step S223 is the second possible amount (P2) ≧ target level (TL), suppression control is executed under the conditions stored in the first condition storage area 235b in step S224. At the start of the suppression control, the control information storage area 235d stores the start time of the suppression control.

  On the other hand, if the second possible amount (P2) <the target level (TL), in step S244, the suppression control is executed under the conditions stored in the second condition storage area 235g. At the start of the suppression control, the start time of the suppression control is stored in the control information storage area 235d.

  Note that steps S225 to S231 and steps S245 to S251 related to the release of the suppression control are the same as steps S116 to S122 and steps S136 to S142 of the first embodiment, respectively, and thus description thereof is omitted.

(4) Features The present embodiment has the same features as the first embodiment except that the unit price of energy is distributed.

(5) Modification The gist of Modification 1A according to the first embodiment and 1C to 1I also applies to the second embodiment. In addition, the 1st energy suppression possible amount and the 2nd energy suppression possible amount of the modified example 1A are read as the first possible amount and the second possible amount, respectively. The term “immediately after receiving the suppression request” in Modification 1G is read as “immediately after reaching the candidate time”.

  The storage unit 314 stores information on incentives and penalties determined in advance between the power company 1 and the properties A and B.

  Here, the information related to incentives is information related to a discount fee that is obtained when energy consumption is suppressed below the required energy suppression amount for a predetermined period. The information related to the penalty is information related to an extra charge when the energy consumption exceeds the energy suppression request amount during a predetermined period.

  Specifically, the information on incentives was able to continue to suppress power below the required energy suppression amount for a certain period of time while properties A and B were being requested for suppression control from power company 1 to properties A and B. In this case, it is information that the unit price per amount of power of the properties A and B is discounted by 1 yen for the time period. Information on the penalty is the unit price per power amount during the suppression control period when the power exceeds the energy suppression request amount even once during the request for suppression control from the power company 1 to the property A or B. The information is to add 2 yen.

  Note that the above information on incentives and penalties is an example, and the incentives and penalties are not limited to information on discounted charges and premiums. The incentive may be an economic merit that induces the user to reduce power usage, and the penalty may be an economic demerit that suppresses an increase in power usage by the user.

The flowchart showing the flow of presentation of the first energy suppression possible amount in the control device 330 to the management device 310 is the same as in FIG. 9 of the first embodiment in the third embodiment, and the description thereof will be omitted.

  In the present embodiment, it is determined whether the actual value satisfies the target level for the entire equipment, and the execution of the suppression control is released separately for the air conditioners 40, 40... And other equipment. Is going. However, for each type of equipment, for each equipment location, and for each equipment, the actual value is grasped, the predicted actual value is predicted, and the achievement level of the target level is judged. The suppression control may be released for each location and for each facility device. Moreover, suppression control may be cancelled | released by either the 1st or 2nd cancellation | release part 336j, 336l about all the installation apparatuses.

  In step S411, the communication unit 331 receives an energy consumption suppression request from the management device 310 together with information on the energy suppression request amount, the suppression request time, the incentive and the penalty, and stores the request in the request storage area 335c. The timing of the suppression request is irregular.

  In step S412, the determination unit 336g determines a calculation condition for the first energy suppression possible amount corresponding to the distributed energy suppression request amount based on the energy suppression request amount and suppression request time distributed from the management device 310.

  In step S413, the recalculation unit 336h calculates the second energy suppression possible amount (PE2 in FIG. 22a) under the same conditions as those determined in step S412.

  In step S414, the second energy suppression possible amount (PE2) is compared with the energy suppression request amount (D in FIG. 22a) stored in the request storage area 335c.

  If the result of step S414 is the second energy suppression possible amount (PE2) ≦ the energy suppression required amount (D), the process proceeds to step S415, and the suppression control is performed using the conditions used for calculating the second energy suppression possible amount. Be started. At this time, the start time of the suppression control is stored in the control information storage area 335d.

  In step S416, the actual energy grasping unit 336f grasps the reduced energy price (actual value). The actual value grasped by the achievement grasping unit 336f is stored in the control information storage area 335d.

  In step S417, it is determined whether or not the actual value stored in the control information storage area 335d has reached the target level stored in the target storage area 335g.

  When it is determined in step S417 that the target level has been achieved, prediction by the second prediction unit 336m is started in step S420.

  If it is determined in step S417 that the actual value has not reached the target level, the process proceeds to step S418. In step S418, it is determined whether the suppression request time has ended. If it is determined that the request time has ended, the execution of the suppression control is ended. If it is determined that the request time has not ended, the process returns to step S416. Steps S416 and S417 are repeatedly executed every predetermined period (in this embodiment, every 5 minutes) until it is determined in step S418 that the suppression request time has ended.

  In step S420, the second prediction unit 336m calculates, as a predicted actual value, an energy price that is predicted to be reduced at the end of the suppression request time when the suppression control is immediately canceled.

  In step S421, the predicted actual value is predicted to be reduced when the suppression request time elapses when the predicted actual value determination unit 336n satisfies the target level, that is, when the suppression control is immediately canceled. It is determined whether or not becomes equal to or higher than the target level. If it is determined in step S421 that the predicted performance value has reached the target level, the process proceeds to step S422. If it is determined in step S421 that the predicted performance value has not reached the target level, the process proceeds to step S426.

  Since the process from step S422 to step S425 is the same as the process from step S119 to step S122 of the first embodiment, the description thereof is omitted.

  In step S426, it is determined whether the suppression control is relaxed. If the suppression control is not relaxed, the process proceeds to step S427. If the suppression control is relaxed, the process proceeds to step S428.

  In step S427, the mitigation unit 336o commands the adjustment control unit 336c to mitigate the execution of the suppression control for all the equipment devices. The adjustment control unit 336c starts executing suppression control using the conditions of the relaxation condition storage area 335l.

  In step S428, it is determined whether the suppression request time has ended. If it is determined that the request time has ended, the execution of the suppression control is ended. If it is determined that the requested time has not ended, the process returns to step S420.

  On the other hand, when the second energy suppression possible amount (PE2)> the energy suppression required amount (D), suppression control is started using the condition of the second condition storage area 335f in step S435. In step S435, the start time of the suppression control is stored in the control information storage area 335d. Thereafter, the process proceeds to step S436.

  Step S436 to step S438, step S440 to step S445, step S446, and step S448 are the same as step S416 to step S418, step S420 to step S425, step S426, and step S428, respectively, and thus description thereof is omitted.

  In the relaxation of the suppression control in step S447, the relaxation unit 336o commands the adjustment control unit 336c to relax the execution of the suppression control for all equipment devices, and the adjustment control unit 336c sets the conditions of the first condition storage area 335b. The execution of the used suppression control is started. Thereafter, the process proceeds to step S462.

(4) Features The control device 330 according to the third embodiment has the following features in addition to the features according to the first embodiment.

(4-1)
The control device 330 for controlling the equipment (air conditioners 40, 40,..., Lighting 50, 50,..., Ventilation fans 60, 60,...) According to the present embodiment is the second prediction unit 336m. And a predicted performance value determination unit 336n. The second prediction unit 336m predicts the transition of power during the second predetermined period (from the time of prediction by the second prediction unit 336m to the end of the suppression request time). Further, the second prediction unit 336m predicts a predicted actual value (energy price predicted to be reduced at the end of the suppression request time) after the second predetermined period as a predicted actual value based on the predicted power transition. To do. That is, the second prediction unit 336m functions as an energy consumption prediction unit and an actual value prediction unit. The predicted actual value determination unit 336n determines whether the predicted actual value satisfies the target level set for the actual value. The first canceling unit 336j cancels the execution of the suppression control based on the determination result of the actual value determining unit 336i and the determination result of the predicted actual value determining unit 336n.

  As a result, the execution of the suppression control is canceled in consideration of the predicted actual value after the elapse of the second predetermined period, so even if the actual value has once reached the target level, the second predetermined is achieved by canceling the suppression control. It is possible to prevent the actual value from reaching the target level after the period has elapsed.

(4-2)
The control device 330 that controls facility equipment according to the present embodiment further includes a relaxation unit 336o. The relaxation unit 336o relaxes the suppression control based on the determination result of the predicted actual value determination unit 336n. The relaxation unit 336o relaxes the suppression control based on the determination result of the actual value determination unit 336i when the execution of the suppression control is not canceled by the first cancellation unit 336j.

  Here, since the suppression control is relaxed even when the execution of the suppression control is not cancelled, the user's comfort is easily improved. Further, since the execution of the suppression control is not canceled, it is easy to prevent the actual value from reaching the target level after a predetermined period.

(5) Modifications The gist of Modification Examples 1A to 1C and 1F to 1J according to the first embodiment also applies to the third embodiment. Moreover, the modification in 3rd Embodiment is shown below.

(5-1) Modification 3A
In the present embodiment, even if the actual value reaches the target level, if the predicted actual value does not reach the target level, the suppression control is relaxed. However, the control device 330 is not limited to this. As shown in FIG. 23, a delay unit 336p may be provided instead of the mitigation unit 336o, and execution of suppression control may be delayed.

  For example, the delay unit 336p delays a command for canceling execution of suppression control for the adjustment control unit 336c of the first cancellation unit 336j by a predetermined time. At this time, the delay time may be different depending on the type of equipment. Moreover, if the delay part 336p cancels | releases suppression control, in order to ensure a user's comfort, about the equipment which may increase the usage-amount of electric power rapidly, for example, about air conditioners 40, 40 ... Takes a long time to delay, and if it arrives at other equipment, the delay time may be shortened or zero.

  Further, the delay unit 336p may delay the time when the first canceling unit 336j commands the adjustment control unit 336c to cancel the execution of the suppression control based on the relationship with the target level with the predicted actual value. More specifically, the delay unit 336p delays execution of the suppression control until the actual value reaches the target level and the predicted actual value reaches the target level.

  Here, because the execution of suppression control is delayed taking into account the predicted actual value, the actual value does not reach the target level after a predetermined period of time compared to when the suppression control is canceled based on the current actual value alone. Easy to prevent from becoming.

(5-2) Modification 3B
In the present embodiment, when the actual value reaches the target level and the predicted actual value does not reach the target level, the suppression control is relaxed, but the present invention is not limited to this.

  For example, the relaxation unit 336o may not relax the suppression control until it is determined that the predicted performance value reaches the target level even if the suppression control is relaxed.

  In this case, the target level is surely easily achieved.

(5-3) Modification 3C
In this embodiment, when the actual value reaches the target level and the predicted actual value does not reach the target level, the suppression control is relaxed only in one stage, but the present invention is not limited to this.

  For example, the storage unit 335 may store conditions for mitigating multistage suppression control, and the suppression control may be relaxed in multiple stages. When mitigating suppression control in multiple stages, the stage of relaxation of suppression control may be changed depending on the elapsed time, and the stage of relaxation of suppression control is changed based on the difference between the predicted actual value and the target level. May be.

  By relaxing the suppression control in multiple stages, the user's comfort and the achievement of the target level are easily executed with high accuracy.

(5-4) Modification 3D
In the present embodiment, when the actual value reaches the target level and the predicted actual value does not reach the target level, the suppression control is relaxed for all the facility devices, but the present invention is not limited to this.

  For example, if the mitigation unit 336o cancels the suppression control, the equipment that may suddenly increase the amount of power used to ensure the user's comfort, such as the air conditioners 40, 40. Only the suppression control may be relaxed. For other equipment, execution of suppression control may be canceled when the actual value reaches the target level.

  Thereby, it becomes easy to achieve the target level of the actual value while ensuring the user's comfort.
