  The determination unit 36b uses the lowest unit price information created from the unit price information for one or more time zones received by the communication unit 31, and adjusts the energy within a predetermined period (one day in the present embodiment). A candidate time zone in which control is to be executed is determined.

  The cheapest unit price information is information determined by the determination unit 36b as described below and stored in the cheapest unit price storage area 35f.

  When a plurality of unit price information exists in the same time zone, the determination unit 36b compares the energy unit prices of the electric power companies and determines the lowest unit price (lowest energy unit price) for each time zone as shown in FIG. To do. About the time slot | zone when the several electric power company showed the same energy unit price, which electric power company is selected is defined beforehand, for example. When there is only one electric power company, the unit price information provided is determined as the lowest unit price information as it is. The determined lowest unit price information for each time zone is stored in the lowest unit price storage area 35f together with the name of the power company providing the lowest unit price as shown in FIG.

  In addition, in this embodiment, the determination unit 36b 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 36b may select a time zone in which the energy unit price exceeds a predetermined value and determine it as a candidate time zone. FIG. 10 illustrates a method for determining a time zone in which the energy unit price exceeds a predetermined value as a 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 through the input unit 33 and updated. The predetermined value may be a value that is appropriately calculated by the determination unit 36b from unit price information such as an average value or an intermediate value of energy unit prices.

  Hereinafter, a method for determining a candidate time zone will be described in detail by taking as an example a case where a time zone in which the energy unit price is maximum within a predetermined period is set as the candidate time zone. Here, a case where there are a plurality of electric power companies will be described.

  First, in this embodiment, the determination unit 36b 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 is present in the unit price storage area 35c at 9:00 am. Then, the energy unit price of each electric power company is compared for each time zone, a unit price comparison table for each time zone is created as shown in FIG. 9, and the lowest unit price is determined. The determined lowest unit price information is stored in the lowest unit price storage area 35f, for example, in the format shown in FIG.

  After that, the determination unit 36b determines, as a candidate time zone, a time zone in which the energy unit price is maximum within a predetermined period based on the information stored in the cheapest unit price storage area 35f. For example, in the example of FIG. 6, the determination unit 36b is the 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 am to 9 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 36b will be described.

  The determination unit 36b calculates a product of the unit price information stored in the lowest unit price storage area 35f and the energy consumption predicted by the prediction unit 36f described later. As a specific process, the determination unit 36b reads the unit price information stored in the cheapest unit price storage area 35f and the predicted energy consumption information stored in the predicted quantity storage area 35g, and calculates the product by time. To do.

  More specifically, when the unit price information of FIG. 6 is stored in the cheapest unit price storage area 35f and the predicted energy consumption amount of FIG. 7 is stored in the predicted amount storage area 35g, the energy unit price and energy by time are stored. The consumption amount is multiplied, and a table of predicted energy prices as shown in FIG. 8 is created. The created information is stored in the predicted price storage area 35h.

  The predicted energy price calculated in this way is output to the output unit 32, so that the user can know the price of energy predicted in advance.

  Further, the predicted energy price may be used as an index including an element of energy unit price when the determination unit 36b determines a candidate time zone. Specifically, when the predicted energy price is calculated as shown in FIG. 8, for example, from 13:00 to 15:00 when the predicted energy price is maximum is determined as the candidate time zone. The determination unit 36b may select a time zone in which the predicted energy price exceeds a predetermined value and determine it as a candidate time zone. Note that the predetermined value may be a fixed value, a value that can be updated by a user input from the input unit 33, or the determining unit 36b such as an average value or an intermediate value of an expected energy price may be appropriately selected. It may be a calculated value.

(2-2-6-3) Energy calculation unit 36c
The energy calculation unit 36c calculates an energy adjustable amount that can be adjusted when the energy adjustment control is performed according to the conditions in the candidate time zone. The calculation of the energy adjustable amount is executed immediately before the start of the candidate time zone. The condition is a condition stored in the above-described condition storage area 35b. In the present embodiment, the energy adjustment control weight set for the duration of the energy adjustment control is used as a condition.

  In the present embodiment, the energy adjustable amount is calculated as follows.

  First, the energy calculation unit 36c calls the energy consumption amount [kW] per unit time acquired by the driving state grasping unit 36a immediately before the calculation of the energy adjustable amount from the driving state storage area 35a. After that, the energy calculation unit 36c calculates the energy consumption W1 when the air conditioners 40, 40... Are operated with the energy consumption per unit time in the candidate time zone. Next, the energy consumption W2 is calculated when the energy adjustment control is performed according to the conditions in the candidate time zone. The difference (W1-W2) between the two energy consumption amounts is calculated as an energy adjustable amount.

W1 and W2 are represented by the following equations.
(Formula 1) W1 = w × ΔT
(Expression 2) W2 = Σ (w × (1−k2n × k1) × Δtn) + w × (ΔT−ΣΔtn)

  Here, w is the energy consumption per unit time [kW] immediately before the candidate time zone, ΔT is the length of the candidate time zone [hr], and Δtn is the duration of the nth energy adjustment control within the candidate time zone [ hr], k1 represents the energy consumption reduction rate [%], and k2n represents the weight of the nth energy adjustment control in the candidate time zone.

Note that W2 may be represented by the following equation, for example.
(Expression 3) W2 = Σ ((w−k2n × Δw) × Δtn) + w × (ΔT−ΣΔtn)

  Here, Δw is the energy consumption [kW] adjusted per unit time.

  In the present embodiment, the energy consumption reduction rate k1 [%] and the energy consumption Δw [kW] adjusted per unit time are within the allowable range of the state value representing the user's indoor environment even if the energy adjustment control is executed. It is a fixed value determined so as to be within. However, it is not necessary to be a fixed value, and k1 and Δw may be values that can be updated by the user through the input unit 33, for example, using information stored in the driving situation storage area 35a. The value may be updated as appropriate.

  In the present embodiment, the candidate time zone is divided into a plurality of times depending on the length of the candidate time zone. Then, for each divided time zone, the energy adjustable amount when energy adjustment control is executed according to the condition is calculated, and the sum is calculated as the final energy adjustable amount.

  This will be specifically described below. Information regarding division of candidate time zones is stored in the condition storage area 35b.

  In the present embodiment, if the candidate time zone is within 2 hours, the entire candidate time zone is set as the execution time of the energy adjustment control. That is, the energy suppression possible amount when energy adjustment control is executed according to the conditions of FIG. 4 in the candidate time zone is calculated.

  On the other hand, if the candidate time zone exceeds 2 hours, the energy suppression possible amount is calculated for the first 2 hours when the energy adjustment control is executed under the condition of 120 minutes in FIG. After that, 30 minutes is preset when the energy adjustment control is canceled. Therefore, the energy adjustable amount for 30 minutes is zero.

  And, if the remaining candidate time zone after subtracting the first 2 hours and 30 minutes to cancel the control is within 120 minutes, the energy adjustment control is executed according to the condition corresponding to the length of the remaining time The amount of energy that can be suppressed is calculated. Then, the final energy adjustable amount is calculated by adding the energy adjustable amount for the first two hours.

  On the other hand, if the remaining time zone is 2 hours or more, the above-described processing when the candidate time zone exceeds 2 hours is repeated.

  However, the method of dividing the candidate time zone is not limited to the above. For example, the division method may be appropriately changed according to the state value of the indoor environment, the length of the candidate time zone, and the like.

  Specifically, the calculation of the energy adjustable amount in the present embodiment will be described by giving an example. For example, it is assumed that the air conditioners 40, 40... Are currently operating, and 100 kW of power is being used immediately before the candidate time for energy adjustment control. The energy consumption reduction rate is determined to be 10%, for example. Then, it is assumed that the information of FIG. 4 is stored as a condition in the condition storage area 35b with respect to the duration of the energy adjustment control. The candidate time zone for energy adjustment control is 3 hours.

  In this case, since the candidate time zone exceeds 2 hours, the division is performed, and the energy adjustment control is executed with the energy adjustment control weight 0.7 for the first 2 hours. After that, the energy adjustment control is executed with the energy adjustment control weight 1.5 for the last 30 minutes with a time period during which the energy adjustment control for 30 minutes is canceled.

  At this time, W1 = 100 [kW] × 3 [hr] = 300 [kWh], W2 = (100 [kW] × (1− (0.7 × 10%)) × 2 [hr] +100 [kW] × (1- (1.5 × 10%)) × 0.5 [hr]) + 100 [kW] × (3-2.5) [hr] = 278.5 [kWh], and the energy adjustable amount ( W1-W2) is calculated as 21.5 [kWh].

(2-2-6-4) Adjustment unit 36d
The adjustment unit 36d performs energy adjustment control in the candidate time zone according to the conditions stored in the condition storage area 35b. In the energy adjustment control, the same candidate time zone as the calculation of the energy adjustable amount is divided, and the energy adjustment control is executed according to the condition in each divided time zone.

  For example, in the example shown in the specific example of the energy adjustable amount above, the energy adjustment control weight 0.7 is 10% per unit time for the first 2 hours with respect to the candidate time zone of 3 hours. Consumption is reduced. That is, the energy adjustment control that reduces the energy consumption by 7% per unit time is executed. After that, the energy adjustment control for 30 minutes is cancelled, and the energy consumption amount of 10% per unit time is reduced by the energy adjustment control weight 1.5 for 30 minutes.

(2-2-6-5) Supply company instruction section 36e
Based on the data stored in the cheapest unit price storage area 35f, the supply company instructing unit 36e gives an instruction to a switchboard (not shown) to purchase power from the cheapest power supply company hourly.

(2-2-6-6) Prediction unit 36f
The prediction unit 36f predicts the energy consumption amount for a predetermined period (one day in the present embodiment). In the present embodiment, the past energy consumption is used as it is as the predicted energy consumption. The predicted energy consumption amount is stored in the predicted amount storage area 35g.

  Specifically, in this embodiment, information on the energy consumption for every hour from 9:00 on the previous day to 9:00 on the current day is used as the predicted energy consumption for each hour from 9:00 on the current day to 9:00 on the next day. Use as is. FIG. 7 is an example of information on the predicted energy consumption to be created. Although FIG. 7 shows information on the predicted energy consumption for each hour, the energy consumption may be predicted at shorter time intervals or longer time intervals.

  The method for predicting energy consumption is not limited to the above method. For example, the hourly energy consumption may be calculated statistically from the energy consumption for the past week. Further, instead of or in addition to the past information, for example, the energy consumption may be predicted based on data such as weather forecast for the day.

(3) Regarding Control Process Performed by Energy Management System 100 FIG. 11 is a flowchart showing a flow of candidate time zone determination processing in the control device 30. FIG. 12 is a flowchart showing a flow of processing of energy adjustment control in the control device 30. The processes shown in FIGS. 11 and 12 are independent of each other. Hereinafter, the flow of processing in the control device 30 that controls the air conditioners 40, 40... Will be described with reference to FIGS.

  First, FIG. 11 will be described.

  In this embodiment, step S101 is performed every day at 9:00 am. In step S101, the determination unit 36b 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 35c.

  The unit price information is distributed from the management devices 10 and 10 of one or more power companies S and T to the control device 30 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 35c.

  In step S102, the determination unit 36b compares the energy unit price of each electric power company for each time zone based on the energy unit price information read in step S101, and determines the cheapest unit price for each time 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 cheapest unit price for each time zone is stored in the cheapest unit price storage area 35f together with the name of the electric power company presenting the lowest unit price.

  In step S103, the prediction unit 36f reads the past energy consumption from the driving state storage area 35a, and executes prediction of energy consumption by time for a predetermined period (in the present embodiment, from 9 am on the current day to 9 am on the next day). To do. The predicted energy consumption amount is stored in the predicted amount storage area 35g.

  In step S104, the determination unit 36b uses the information on the cheapest unit price information in the cheapest unit price storage area 35f and the predicted energy consumption amount in the predicted amount storage area 35g to calculate the unit price for each hour and the predicted energy consumption amount. Find the product. As a result, for example, a table of predicted energy prices for each hour as shown in FIG. 8 is created. A table of predicted energy prices is stored in the predicted price storage area 35h.

  In step S105, the determination unit 36b 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. The cheapest unit price information stored in the cheapest unit price storage area 35f is used for the determination. 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 35d. Moreover, in step S105, instead of the energy unit price, the predicted energy price stored in the predicted price storage area 35h may be used for determining the candidate time zone. In addition, when determining a candidate time slot | zone with an energy unit price, step S103 and step S104 are unnecessary for the determination process of a candidate time slot | zone.

  Next, FIG. 12 will be described.

  In step S111, the energy calculation unit 36c reaches the start time of the candidate time zone within 5 minutes using the current time presented by the time management unit 34 and the information stored in the candidate time zone storage area 35d. Determine if you want to.

  For example, when the current time of the time management unit 34 is 12:56 and the information of FIG. 13 is stored in the candidate time zone storage area 35d, the adjustment unit 36d that has read the information of FIG. It is determined that the candidate time zone starts.

  In step S112, the energy calculation unit 36c first refers to the driving status storage area 35a, and the energy calculating unit 36c refers to the energy consumption per unit time (kW) included in the current (latest) driving status data. Call.

  In step S113, the energy calculation unit 36c calculates an energy adjustable amount using the energy consumption per unit time called in step S112 and the information stored in the condition storage area 35b. The calculated energy adjustable amount and the corresponding energy price are output to the output unit 32 and stored in the control information storage area 35e.

  The energy price corresponding to the energy adjustable amount is calculated by calculating the energy adjustable amount for each energy unit price and integrating the products.

  In step S114, the adjustment unit 36d determines whether the candidate time zone has been reached using the current time presented by the time management unit 34 and the information stored in the candidate time zone storage area 35d. If the candidate time has been reached, the energy adjustment control is executed using the information stored in the condition storage area 35b in step S115. When the energy adjustment control is started in step S115, the time when the energy adjustment control is started is stored.

  In step S116, the time management unit 34 determines whether or not the candidate time zone stored in the candidate time zone storage area 35d has ended. If there are a plurality of candidate time zones, it is determined whether or not the earliest candidate time zone has ended. When it determines with complete | finishing, it transfers to step S117, and the adjustment part 36d complete | finishes energy adjustment control. Specifically, the adjustment unit 36d instructs the air conditioners 40, 40... To cancel the energy adjustment control. When canceling the energy adjustment control, for example, the end time of the energy adjustment control, the energy consumption during the energy adjustment control, the energy consumption actually adjusted by the energy adjustment control, and these amounts are stored in the control information storage area 35e. The energy price corresponding to is stored. The energy consumption amount is stored based on information stored in the driving situation storage area 35a. Note that the information about the candidate time zone that has already passed is deleted from the candidate time zone storage area 35d.

  Thereafter, the process returns to step S111 and the process is repeated.

(4) Features (4-1)
In the present embodiment, the control device 30 controls the air conditioners 40, 40..., And includes a communication unit 31, a determination unit 36b, an energy calculation unit 36c, and an adjustment unit 36d.

Therefore, it is possible to grasp the amount of energy reduction in advance, and the user comfort is easily maintained when the energy adjustment control is executed.

(4-2)
In this embodiment, the driving condition grasping part 36a grasps the driving condition of the air conditioners 40, 40..., And the energy calculating part 36c calculates the energy adjustable amount with reference to the driving condition.

  As a result, the energy adjustable amount according to the operation status of the equipment is calculated.

(4-3)
In this embodiment, the determination part 36b determines the time slot | zone where an energy unit price becomes the maximum, or the time slot | zone exceeding a predetermined value as a candidate time slot | zone. Furthermore, the energy calculation unit 36c calculates an energy adjustable amount that can be adjusted when the energy consumption is suppressed. Control according to the energy supplier's intention to suppress energy consumption during peak demand becomes easy. Users also have the advantage of reducing energy costs.

(4-4)
In this embodiment, the prediction part 36f which estimates energy consumption is provided. The determination unit 36b determines a time zone in which the product of the energy consumption predicted by the prediction unit 36f and the unit price information is maximum, or a time zone in which the product exceeds a predetermined value as a candidate time zone. The energy calculation unit 36c calculates an energy adjustable amount that can be adjusted when the energy consumption is suppressed.

  Here, since the energy suppression control is performed in a time zone in which the predicted energy price is high, the user can efficiently reduce the energy price.

(4-5)
In the present embodiment, the condition used for the energy calculation unit 36c and the adjustment unit 36d is the weight of the intensity of energy adjustment control.

  Here, the energy adjustment control can be executed by changing the intensity of the energy adjustment control.

(4-6)
In the present embodiment, the conditions used for the energy calculation unit 36c and the adjustment unit 36d are set for the duration of the energy adjustment control, and the energy adjustment control is longer than when the duration is longer. It is set so that the amount of suppression per unit time of the energy consumption is small.

  Here, the condition is set so that the amount of energy suppression per unit time decreases as the duration of the energy adjustment control increases. Therefore, it becomes easy to balance energy consumption suppression and user comfort.

(4-7)
In the present embodiment, the energy calculation unit 36c divides the candidate time zone into a plurality of time zones when the length of the candidate time zone is longer than a predetermined time, and performs energy adjustment control for each of the divided time zones. The amount of energy adjustment that can be performed according to the conditions is calculated.

  Thereby, flexible energy adjustment control is easy to be realized.

(4-8)

  Here, the user can grasp the energy adjustable amount and the actually adjusted energy consumption amount. The grasped information can be used for, for example, judgment materials for examining the operation method and reporting of the energy usage status.

(5) Modification (5-1) Modification 1A
The mode of outputting unit price information from the management devices 10 and 10 of the energy supply company is not limited to that described above. For example, the unit price information may be faxed through a telephone communication line. In this case, the control device 30 accepts the unit price information described in the FAX input by the user via the input unit 33.

(5-2) Modification 1B
The energy calculation unit 36c changes the energy consumption (kW) per unit time immediately before the candidate time zone, for example, 30 before the candidate time zone, when executing the calculations of (Equation 1) to (Equation 3). An average value of energy consumption per unit time per minute may be used. By referring to the driving situation for a certain period, it is possible to calculate an energy adjustable amount closer to the actual value.

  Further, for example, the calculation may be executed using an average of power consumption for 30 minutes in the same time zone of the previous day.

(5-3) Modification 1C
The method for determining the candidate time zone is not limited to the above. For example, the determination unit 36b may determine a time zone in which the energy unit price is minimum or a time zone in which the energy unit price is lower than a predetermined value as a candidate time zone in which the energy adjustment control is to be executed. In this case, energy adjustment control for increasing the energy consumption amount in the candidate time zone is executed. For example, by preheating or storing air conditioning equipment during a time period when the energy unit price is cheap, energy consumption during a time when the energy unit price is high is suppressed, and the energy price is reduced.

  In addition, the determination unit 36b determines a time period in which the energy unit price is the maximum, a time period in which the energy unit price exceeds the predetermined value 1, a time period in which the energy unit price is the minimum, or a time in which the energy unit price is less than the predetermined value 2. Both the zone and the zone may be set as candidate time zones. In this case, different energy adjustment control is executed when the energy unit price is high and when it is low. The predetermined value 1 and the predetermined value 2 may be the same value. By executing such energy adjustment control, it becomes easy to execute total energy price adjustment.

(5-4) Modification 1D
The determination unit 36b may determine the candidate time zone using the predicted energy consumption instead of the predicted energy price. For example, a time zone in which the expected energy consumption is maximum or a time exceeding a predetermined value may be determined as the candidate time zone.

(5-5) Modification 1E
The adjustment unit 36d may not execute the selected energy adjustment control when there is a possibility that the comfort cannot be ensured by executing the energy adjustment control. For example, when the energy calculating unit 36c calculates the energy adjustable amount, the measured values of temperature and humidity have not reached the set values even though the current operating capacity is 100%, and the values are determined in advance. If there is a further deviation, the energy adjustment control need not be executed. In addition, for example, the energy adjustment control command may not be executed for a certain period of time after the start of operation.

(5-6) Modification 1F
The air conditioners 40, 40... Are examples of equipment, and for example, lighting, ventilation fans, and combinations thereof may be controlled by the control device 30. Thereby, it is possible to apply this control apparatus with respect to a wide installation. Note that the definition of the energy adjustable amount, that is, the influence on the user's indoor environment is within the allowable range is that the illuminance is maintained within the allowable range, for example, when the equipment is lighting. In the case where the equipment is a ventilation fan, for example, it means that the ventilation amount is maintained in an allowable range.

  Therefore, for example, the conditions in the condition storage area 35b may be set according to illuminance or ventilation volume.

(5-7) Modification 1G
The control device 30 does not need to target the entire facility equipment of the property for energy adjustment control, and may execute energy adjustment control for a part thereof. Further, for example, the energy adjustment control may be executed for each type of equipment and for each floor of the property.

(5-8) Modification 1H
The energy calculation unit 36c may calculate an energy adjustable amount for each of a plurality of conditions. For example, as long as the influence on the user's indoor environment is maintained within an allowable range, the energy adjustment control is provided with “energy saving emphasis”, “energy saving / comfort balance”, and “comfort emphasis” as shown in FIG. In addition to the duration of energy adjustment control, conditions are prepared according to the stage. And the energy calculation part 36c calculates the energy adjustable amount which can be adjusted when energy adjustment control is performed according to the conditions according to a step. That is, a plurality of energy adjustable amounts are calculated for each stage. A plurality of energy adjustable amounts and energy prices corresponding to the energy adjustable amounts are output to the output unit 32.

  In this case, the control device 30 further includes a selection unit 36g that selects one condition from a plurality of conditions as shown in FIG.

  For example, the selection unit 36g selects a condition as follows. The user looks at the energy adjustable amount output to the output unit 32 and the corresponding energy price, and selects 1 from “energy saving emphasis”, “comfort emphasis”, and “balance emphasis” and selects the input unit as a selection criterion. 33. The selection unit 36g selects a condition corresponding to the selection criterion input by the user. The adjustment unit 36d performs energy adjustment control under the conditions selected by the selection unit 36g.

  As a result, the user can check the plurality of calculated energy adjustment possible amounts and the corresponding energy prices that can be reduced, select the condition closest to the needs, and execute the energy adjustment control.

  Note that the method by which the selection unit 36g determines the condition is not limited to the above method. For example, instead of the user inputting the selection criterion every time, the selection criterion once input may be used for determining the repetition condition. The selection unit 36g may determine one condition by the following method, for example, instead of or in addition to the input of the user's selection criteria. For example, one condition such that the calculated energy adjustable amount falls within a predetermined value range may be automatically determined by the selection unit 36g. In addition, for example, past driving status stored in the driving status storage area 35a and past energy adjustment control information stored in the control information storage area 35e, expected power consumption, expected energy price, environmental conditions The condition 1 may be determined in consideration of the operating status of the equipment.

The conditions stored in the condition storage area 235b are conditions related to the pattern of energy adjustment control. The pattern of energy adjustment control is a combination of the execution time of energy adjustment control and the release time of energy adjustment control.

  The condition is used by an energy calculation unit 236c described later to calculate an energy adjustable amount. The adjusting unit 236d described later performs energy adjustment control according to the conditions. The condition is that even if the energy adjustment control is executed using this, the influence on the user's indoor environment, for example, room temperature and humidity is within an allowable range with respect to the set temperature and set humidity, and the user's profit, For example, it is determined in advance so that the energy price and the reduction amount of energy consumption can be as large as possible.

(1-1-2-1) Energy calculation unit 236c
The energy calculation unit 236c calculates an adjustable energy amount that can be adjusted when the energy adjustment control is performed according to the conditions in the candidate time zone. The calculation of the energy adjustable amount is executed immediately before the start of the candidate time zone. The condition is a condition stored in the above-described condition storage area 235b.

  In the present embodiment, the energy adjustable amount is calculated as follows.

  First, the energy calculation unit 236c calls the energy consumption amount [kW] per unit time acquired by the driving state grasping unit 236a immediately before calculating the energy adjustable amount from the driving state storage area 235a. After that, the energy calculation unit 236c calculates the energy consumption W3 when the air conditioners 40, 40... Are operated with the energy consumption per unit time in the candidate time zone. Next, an energy consumption amount W4 when energy adjustment control is performed according to the conditions in the candidate time zone is calculated. A difference (W3−W4) between the two energy consumption amounts is calculated as an energy adjustable amount.

W3 and W4 are each represented by the following equations.
(Formula 4) W3 = w × ΔT
(Formula 5) W4 = Σ (w × (1−k1) × Δtn) + w × (ΔT−ΣΔtn)

  Here, w is the energy consumption [kW] per unit time immediately before the candidate time zone, ΔT is the length of the candidate time zone [hr], and Δtn is the continuation of the nth energy adjustment control in the candidate time zone. Time [hr], k1 represents the energy consumption reduction rate [%].

Note that W4 is not limited to the above calculation method, and may be expressed by the following equation, for example.
(Expression 6) W4 = Σ ((w−Δw) × Δtn) + w × (ΔT−ΣΔtn)

  Here, Δw is the energy consumption [kW] adjusted per unit time.

  In the present embodiment, the energy consumption reduction rate k1 [%] and the energy consumption Δw [kW] adjusted per unit time are the state values representing the user's indoor environment even when the energy adjustment control is executed. It is a fixed value determined so as to be within an allowable range. However, it is not necessary to be a fixed value, and k1 and Δw may be values that can be updated by the user through the input unit 33. For example, information stored in the driving situation storage area 35a is used. The value may be updated as appropriate.

  Specifically, the calculation of the energy adjustable amount in the present embodiment will be described by giving a case example. For example, air conditioners 40, 40... Are currently operating, and 100 kW of power is used immediately before the candidate time for energy adjustment control. The energy consumption reduction rate is determined to be 10%, and it is assumed that FIG. 18 is stored as a condition in the condition storage area 235b with respect to the duration of the energy adjustment control. It is assumed that the candidate time zone for energy adjustment control is 2 hours. In this case, energy adjustment control is executed for the first 60 minutes. Thereafter, the energy adjustment control is canceled for 30 minutes, and then the energy adjustment control is executed again for the remaining 30 minutes.

  At this time, W1 = 100 [kW] × 2 [hr] = 200 [kWh] and W2 = (100 [kW] × (1-10%) × (1 + 0.5) [hr] +100 [kW] × (2- (1 + 0.5)) [hr] = 185 [kWh] is calculated, and the energy adjustable amount (W1-W2) = 15 [kWh] is calculated.

  In the present embodiment, similarly to the first embodiment, when the candidate time zone is longer than a predetermined time (for example, 3 hours), the candidate time zone is divided into a plurality of times. Then, for each divided time zone, the energy adjustable amount when energy adjustment control is executed according to the condition is calculated, and the sum is calculated as the final energy adjustable amount.

(1-1-2-2) Adjustment unit 236d
The adjustment unit 236d performs energy adjustment control according to the conditions stored in the condition storage area 235b in the candidate time zone.

  For example, in the case shown in the specific example of the energy adjustable amount, the energy adjustment control is executed to reduce the energy consumption by 10% for the first 60 minutes with respect to the candidate time zone of 2 hours. Thereafter, after the energy adjustment control is canceled for 30 minutes, the energy adjustment control is executed again for the remaining 30 minutes.

  When the candidate time zone is divided when calculating the energy adjustable amount, the same candidate time zone is divided during energy adjustment control as when the energy adjustable amount is calculated. In each divided time zone, energy adjustment control is executed according to conditions.

On the other hand, since the energy unit price fluctuates in the candidate time zone as shown in FIG. 21, the reduction amount of the energy price in the conditions 1 to 3 is 375 yen, 350 yen, and 400 yen, respectively. At this time, the selection unit 236g selects the condition 3 that maximizes the reduction amount of the energy price. The adjustment unit 236d performs energy adjustment control under the conditions selected by the selection unit 236g.

  Instead of the selection unit 236g automatically selecting a condition, the input unit 233 may receive an input as to which condition is selected from the user, and the selection unit 236g may select the condition according to the user's input.

  By accepting input from the user, it is possible to execute energy adjustment control by selecting conditions close to the user's needs.

(4-2) Modification 2B
In the condition storage area 235b, for example, as shown in FIG. 22, conditions relating to both the energy adjustment control pattern and the intensity of the energy adjustment control of the first embodiment may be stored.

The value acquired by the driving status grasping unit 36a is stored in the above-described driving status storage area 35a together with the date and time of data acquisition.

(2-2-6-2) Determination unit 36b
The determination unit 36b mainly performs two processes of determining a candidate time zone and calculating a predicted energy price.

  The candidate time zone is determined as follows.

  The determination unit 36b uses the lowest unit price information created from the unit price information for one or more time zones received by the communication unit 31, and adjusts the energy within a predetermined period (one day in the present embodiment). A candidate time zone in which control is to be executed is determined.

  The cheapest unit price information is information determined by the determination unit 36b as described below and stored in the cheapest unit price storage area 35f.

  When a plurality of unit price information exists in the same time zone, the determination unit 36b compares the energy unit prices of the electric power companies and determines the lowest unit price (lowest energy unit price) for each time zone as shown in FIG. To do. About the time slot | zone when the several electric power company showed the same energy unit price, which electric power company is selected is defined beforehand, for example. When there is only one electric power company, the unit price information provided is determined as the lowest unit price information as it is. The determined lowest unit price information for each time zone is stored in the lowest unit price storage area 35f together with the name of the power company providing the lowest unit price as shown in FIG.

  In addition, in this embodiment, the determination unit 36b 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 36b may select a time zone in which the energy unit price exceeds a predetermined value and determine it as a candidate time zone. FIG. 10 illustrates a method for determining a time zone in which the energy unit price exceeds a predetermined value as a 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 through the input unit 33 and updated. The predetermined value may be a value that is appropriately calculated by the determination unit 36b from unit price information such as an average value or an intermediate value of energy unit prices.

Hereinafter, a method for determining a candidate time zone will be described in detail by taking as an example a case where a time zone in which the energy unit price is maximum within a predetermined period is set as the candidate time zone. Here, a case where there are a plurality of electric power companies will be described.
First, in the present embodiment, the determination unit 36b 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 35c at 9:00 am. Then, the energy unit price of each electric power company is compared for each time zone, a unit price comparison table for each time zone is created as shown in FIG. 9, and the lowest unit price is determined. The determined lowest unit price information is stored in the lowest unit price storage area 35f, for example, in the format shown in FIG.

  After that, the determination unit 36b determines, as a candidate time zone, a time zone in which the energy unit price is maximum within a predetermined period based on the information stored in the cheapest unit price storage area 35f. For example, in the example of FIG. 6, the determination unit 36b is the 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 am to 9 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 36b will be described.

  The determination unit 36b calculates a product of the unit price information stored in the lowest unit price storage area 35f and the energy consumption predicted by the prediction unit 36f described later. As a specific process, the determination unit 36b reads the unit price information stored in the cheapest unit price storage area 35f and the predicted energy consumption information stored in the predicted quantity storage area 35g, and calculates the product by time. To do.

  More specifically, when the unit price information of FIG. 6 is stored in the cheapest unit price storage area 35f and the predicted energy consumption amount of FIG. 7 is stored in the predicted amount storage area 35g, the energy unit price and energy by time are stored. The consumption amount is multiplied, and a table of predicted energy prices as shown in FIG. 8 is created. The created information is stored in the predicted price storage area 35h.

  The predicted energy price calculated in this way is output to the output unit 32, so that the user can know the price of energy predicted in advance.

  Further, the predicted energy price may be used as an index including an element of energy unit price when the determination unit 36b determines a candidate time zone. Specifically, when the predicted energy price is calculated as shown in FIG. 8, for example, from 13:00 to 15:00 when the predicted energy price is maximum is determined as the candidate time zone. The determination unit 36b may select a time zone in which the predicted energy price exceeds a predetermined value and determine it as a candidate time zone. Note that the predetermined value may be a fixed value, a value that can be updated by a user input from the input unit 33, or the determining unit 36b such as an average value or an intermediate value of an expected energy price may be appropriately selected. It may be a calculated value.

(2-2-6-3) Energy calculation unit 36c
The energy calculation unit 36c calculates an energy adjustable amount that can be adjusted when the energy adjustment control is performed according to the conditions in the candidate time zone. The calculation of the energy adjustable amount is executed immediately before the start of the candidate time zone. The condition is a condition stored in the above-described condition storage area 35b. In the present embodiment, the energy adjustment control weight set for the duration of the energy adjustment control is used as a condition.

  In the present embodiment, the energy adjustable amount is calculated as follows.

  First, the energy calculation unit 36c calls the energy consumption amount [kW] per unit time acquired by the driving state grasping unit 36a immediately before the calculation of the energy adjustable amount from the driving state storage area 35a. After that, the energy calculation unit 36c calculates the energy consumption W1 when the air conditioners 40, 40... Are operated with the energy consumption per unit time in the candidate time zone. Next, the energy consumption W2 is calculated when the energy adjustment control is performed according to the conditions in the candidate time zone. The difference (W1-W2) between the two energy consumption amounts is calculated as an energy adjustable amount.

  W1 and W2 are represented by the following equations.

(Formula 1) W1 = w × ΔT
(Expression 2) W2 = Σ (w × (1−k2n × k1) × Δtn) + w × (ΔT−ΣΔtn)
Here, w is the energy consumption per unit time [kW] immediately before the candidate time zone, ΔT is the length of the candidate time zone [hr], and Δtn is the duration of the nth energy adjustment control within the candidate time zone [ hr], k1 represents the energy consumption reduction rate [%], and k2n represents the weight of the nth energy adjustment control in the candidate time zone.

  Note that W2 may be represented by the following equation, for example.

(Expression 3) W2 = Σ ((w−k2n × Δw) × Δtn) + w × (ΔT−ΣΔtn)
Here, Δw is the energy consumption [kW] adjusted per unit time.

  In the present embodiment, the energy consumption reduction rate k1 [%] and the energy consumption Δw [kW] adjusted per unit time are within the allowable range of the state value representing the user's indoor environment even if the energy adjustment control is executed. It is a fixed value determined so as to be within. However, it is not necessary to be a fixed value, and k1 and Δw may be values that can be updated by the user through the input unit 33, for example, using information stored in the driving situation storage area 35a. The value may be updated as appropriate.

  In the present embodiment, the candidate time zone is divided into a plurality of times depending on the length of the candidate time zone. Then, for each divided time zone, the energy adjustable amount when energy adjustment control is executed according to the condition is calculated, and the sum is calculated as the final energy adjustable amount.

  This will be specifically described below. Information regarding division of candidate time zones is stored in the condition storage area 35b.

  In the present embodiment, if the candidate time zone is within 2 hours, the entire candidate time zone is set as the execution time of the energy adjustment control. That is, the energy suppression possible amount when energy adjustment control is executed according to the conditions of FIG. 4 in the candidate time zone is calculated.

  On the other hand, if the candidate time zone exceeds 2 hours, the energy suppression possible amount is calculated for the first 2 hours when the energy adjustment control is executed under the condition of 120 minutes in FIG. After that, 30 minutes is preset when the energy adjustment control is canceled. Therefore, the energy adjustable amount for 30 minutes is zero.

  And, if the remaining candidate time zone after subtracting the first 2 hours and 30 minutes to cancel the control is within 120 minutes, the energy adjustment control is executed according to the condition corresponding to the length of the remaining time The amount of energy that can be suppressed is calculated. Then, the final energy adjustable amount is calculated by adding the energy adjustable amount for the first two hours.

  On the other hand, if the remaining time zone is 2 hours or more, the above-described processing when the candidate time zone exceeds 2 hours is repeated.

  However, the method of dividing the candidate time zone is not limited to the above. For example, the division method may be appropriately changed according to the state value of the indoor environment, the length of the candidate time zone, and the like.

  Specifically, the calculation of the energy adjustable amount in the present embodiment will be described by giving an example. For example, it is assumed that the air conditioners 40, 40... Are currently operating, and 100 kW of power is being used immediately before the candidate time for energy adjustment control. The energy consumption reduction rate is determined to be 10%, for example. Then, it is assumed that the information of FIG. 4 is stored as a condition in the condition storage area 35b with respect to the duration of the energy adjustment control. The candidate time zone for energy adjustment control is 3 hours.

  In this case, since the candidate time zone exceeds 2 hours, the division is performed, and the energy adjustment control is executed with the energy adjustment control weight 0.7 for the first 2 hours. After that, the energy adjustment control is executed with the energy adjustment control weight 1.5 for the last 30 minutes with a time period during which the energy adjustment control for 30 minutes is canceled.

  At this time, W1 = 100 [kW] × 3 [hr] = 300 [kWh], W2 = (100 [kW] × (1− (0.7 × 10%)) × 2 [hr] +100 [kW] × (1- (1.5 × 10%)) × 0.5 [hr]) + 100 [kW] × (3-2.5) [hr] = 278.5 [kWh], and the energy adjustable amount ( W1-W2) is calculated as 21.5 [kWh].

(2-2-6-4) Adjustment unit 36d
The adjustment unit 36d performs energy adjustment control in the candidate time zone according to the conditions stored in the condition storage area 35b. In the energy adjustment control, the same candidate time zone as the calculation of the energy adjustable amount is divided, and the energy adjustment control is executed according to the condition in each divided time zone.

  For example, in the example shown in the specific example of the energy adjustable amount above, the energy adjustment control weight 0.7 is 10% per unit time for the first 2 hours with respect to the candidate time zone of 3 hours. Consumption is reduced. That is, the energy adjustment control that reduces the energy consumption by 7% per unit time is executed. After that, the energy adjustment control for 30 minutes is cancelled, and the energy consumption amount of 10% per unit time is reduced by the energy adjustment control weight 1.5 for 30 minutes.

(2-2-6-5) Supply company instruction section 36e
Based on the data stored in the cheapest unit price storage area 35f, the supply company instructing unit 36e gives an instruction to a switchboard (not shown) to purchase power from the cheapest power supply company hourly.

(2-2-6-6) Prediction unit 36f
The prediction unit 36f predicts the energy consumption amount for a predetermined period (one day in the present embodiment). In the present embodiment, the past energy consumption is used as it is as the predicted energy consumption. The predicted energy consumption amount is stored in the predicted amount storage area 35g.

  Specifically, in this embodiment, information on the energy consumption for every hour from 9:00 on the previous day to 9:00 on the current day is used as the predicted energy consumption for each hour from 9:00 on the current day to 9:00 on the next day. Use as is. FIG. 7 is an example of information on the predicted energy consumption to be created. Although FIG. 7 shows information on the predicted energy consumption for each hour, the energy consumption may be predicted at shorter time intervals or longer time intervals.

  The method for predicting energy consumption is not limited to the above method. For example, the hourly energy consumption may be calculated statistically from the energy consumption for the past week. Further, instead of or in addition to the past information, for example, the energy consumption may be predicted based on data such as weather forecast for the day.

(3) Regarding Control Process Performed by Energy Management System 100 FIG. 11 is a flowchart showing a flow of candidate time zone determination processing in the control device 30. FIG. 12 is a flowchart showing a flow of processing of energy adjustment control in the control device 30. The processes shown in FIGS. 11 and 12 are independent of each other. Hereinafter, the flow of processing in the control device 30 that controls the air conditioners 40, 40... Will be described with reference to FIGS.

  First, FIG. 11 will be described.

  In this embodiment, step S101 is performed every day at 9:00 am. In step S101, the determination unit 36b 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 35c.

  The unit price information is distributed from the management devices 10 and 10 of one or more power companies S and T to the control device 30 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 35c.

  In step S102, the determination unit 36b compares the energy unit price of each electric power company for each time zone based on the energy unit price information read in step S101, and determines the cheapest unit price for each time 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 cheapest unit price for each time zone is stored in the cheapest unit price storage area 35f together with the name of the electric power company presenting the lowest unit price.

  In step S103, the prediction unit 36f reads the past energy consumption from the driving state storage area 35a, and executes prediction of energy consumption by time for a predetermined period (in the present embodiment, from 9 am on the current day to 9 am on the next day). To do. The predicted energy consumption amount is stored in the predicted amount storage area 35g.

  In step S104, the determination unit 36b uses the information on the cheapest unit price information in the cheapest unit price storage area 35f and the predicted energy consumption amount in the predicted amount storage area 35g to calculate the unit price for each hour and the predicted energy consumption amount. Find the product. As a result, for example, a table of predicted energy prices for each hour as shown in FIG. 8 is created. A table of predicted energy prices is stored in the predicted price storage area 35h.

  In step S105, the determination unit 36b 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. The cheapest unit price information stored in the cheapest unit price storage area 35f is used for the determination. 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 35d. Moreover, in step S105, instead of the energy unit price, the predicted energy price stored in the predicted price storage area 35h may be used for determining the candidate time zone. In addition, when determining a candidate time slot | zone with an energy unit price, step S103 and step S104 are unnecessary for the determination process of a candidate time slot | zone.

  Next, FIG. 12 will be described.

  In step S111, the energy calculation unit 36c reaches the start time of the candidate time zone within 5 minutes using the current time presented by the time management unit 34 and the information stored in the candidate time zone storage area 35d. Determine if you want to.

  For example, when the current time of the time management unit 34 is 12:56 and the information of FIG. 13 is stored in the candidate time zone storage area 35d, the adjustment unit 36d that has read the information of FIG. It is determined that the candidate time zone starts.

  In step S112, the energy calculation unit 36c first refers to the driving status storage area 35a, and the energy calculating unit 36c refers to the energy consumption per unit time (kW) included in the current (latest) driving status data. Call.

  In step S113, the energy calculation unit 36c calculates an energy adjustable amount using the energy consumption per unit time called in step S112 and the information stored in the condition storage area 35b. The calculated energy adjustable amount and the corresponding energy price are output to the output unit 32 and stored in the control information storage area 35e.

  The energy price corresponding to the energy adjustable amount is calculated by calculating the energy adjustable amount for each energy unit price and integrating the products.

  In step S114, the adjustment unit 36d determines whether the candidate time zone has been reached using the current time presented by the time management unit 34 and the information stored in the candidate time zone storage area 35d. If the candidate time has been reached, the energy adjustment control is executed using the information stored in the condition storage area 35b in step S115. When the energy adjustment control is started in step S115, the time when the energy adjustment control is started is stored.

  In step S116, the time management unit 34 determines whether or not the candidate time zone stored in the candidate time zone storage area 35d has ended. If there are a plurality of candidate time zones, it is determined whether or not the earliest candidate time zone has ended. When it determines with complete | finishing, it transfers to step S117, and the adjustment part 36d complete | finishes energy adjustment control. Specifically, the adjustment unit 36d instructs the air conditioners 40, 40... To cancel the energy adjustment control. When canceling the energy adjustment control, for example, the end time of the energy adjustment control, the energy consumption during the energy adjustment control, the energy consumption actually adjusted by the energy adjustment control, and these amounts are stored in the control information storage area 35e. The energy price corresponding to is stored. The energy consumption amount is stored based on information stored in the driving situation storage area 35a. Note that the information about the candidate time zone that has already passed is deleted from the candidate time zone storage area 35d.

  Thereafter, the process returns to step S111 and the process is repeated.

The amount of energy. The adjustment unit 36d performs energy adjustment control in the candidate time zone according to the above-described conditions.

  When adjusting the energy consumption using the unit price information of energy by time zone, the energy adjustable amount is calculated to the extent that the effect on the user's indoor environment can be kept within the allowable range, and the calculation The energy adjustment control is executed under the conditions that are the preconditions for the above. Therefore, it is possible to grasp the amount of energy reduction in advance, and the user comfort is easily maintained when the energy adjustment control is executed.

(4-2)
In this embodiment, the driving condition grasping part 36a grasps the driving condition of the air conditioners 40, 40..., And the energy calculating part 36c calculates the energy adjustable amount with reference to the driving condition.

  As a result, the energy adjustable amount according to the operation status of the equipment is calculated.

(4-3)
In this embodiment, the determination part 36b determines the time slot | zone where an energy unit price becomes the maximum, or the time slot | zone exceeding a predetermined value as a candidate time slot | zone. Furthermore, the energy calculation unit 36c calculates an energy adjustable amount that can be adjusted when the energy consumption is suppressed. Control according to the energy supplier's intention to suppress energy consumption during peak demand becomes easy. Users also have the advantage of reducing energy costs.

(4-4)
In this embodiment, the prediction part 36f which estimates energy consumption is provided. The determination unit 36b determines a time zone in which the product of the energy consumption predicted by the prediction unit 36f and the unit price information is maximum, or a time zone in which the product exceeds a predetermined value as a candidate time zone. The energy calculation unit 36c calculates an energy adjustable amount that can be adjusted when the energy consumption is suppressed.

  Here, since the energy suppression control is performed in a time zone in which the predicted energy price is high, the user can efficiently reduce the energy price.

(4-5)
In the present embodiment, the condition used for the energy calculation unit 36c and the adjustment unit 36d is the weight of the intensity of energy adjustment control.

  Here, the energy adjustment control can be executed by changing the intensity of the energy adjustment control.

(4-6)

(5) Modification (5-1) Modification 1A
The mode of outputting unit price information from the management devices 10 and 10 of the energy supply company is not limited to that described above. For example, the unit price information may be faxed through a telephone communication line. In this case, the control device 30 accepts the unit price information described in the FAX input by the user via the input unit 33.

(5-2) Modification 1B
The energy calculation unit 36c changes the energy consumption (kW) per unit time immediately before the candidate time zone, for example, 30 before the candidate time zone, when executing the calculations of (Equation 1) to (Equation 3). An average value of energy consumption per unit time per minute may be used. By referring to the driving situation for a certain period, it is possible to calculate an energy adjustable amount closer to the actual value.

  Further, for example, the calculation may be executed using an average of power consumption for 30 minutes in the same time zone of the previous day.

The method for determining the candidate time zone is not limited to the above. For example, the determination unit 36b may determine a time zone in which the energy unit price is minimum or a time zone in which the energy unit price is lower than a predetermined value as a candidate time zone in which the energy adjustment control is to be executed. In this case, energy adjustment control for increasing the energy consumption amount in the candidate time zone is executed. For example, by preheating or storing air conditioning equipment during a time period when the energy unit price is cheap, energy consumption during a time when the energy unit price is high is suppressed, and the energy price is reduced.

  In addition, the determination unit 36b determines a time period in which the energy unit price is the maximum, a time period in which the energy unit price exceeds the predetermined value 1, a time period in which the energy unit price is the minimum, or a time in which the energy unit price is less than the predetermined value 2. Both the zone and the zone may be set as candidate time zones. In this case, different energy adjustment control is executed when the energy unit price is high and when it is low. The predetermined value 1 and the predetermined value 2 may be the same value. By executing such energy adjustment control, it becomes easy to execute total energy price adjustment.

The determination unit 36b may determine the candidate time zone using the predicted energy consumption instead of the predicted energy price. For example, a time zone in which the expected energy consumption is maximum or a time exceeding a predetermined value may be determined as the candidate time zone.

(5-5) Modification 1E
The adjustment unit 36d may not execute the selected energy adjustment control when there is a possibility that the comfort cannot be ensured by executing the energy adjustment control. For example, when the energy calculating unit 36c calculates the energy adjustable amount, the measured values of temperature and humidity have not reached the set values even though the current operating capacity is 100%, and the values are determined in advance. If there is a further deviation, the energy adjustment control need not be executed. In addition, for example, the energy adjustment control command may not be executed for a certain period of time after the start of operation.

(5-6) Modification 1F
The air conditioners 40, 40... Are examples of equipment, and for example, lighting, ventilation fans, and combinations thereof may be controlled by the control device 30. Thereby, it is possible to apply this control apparatus with respect to a wide installation. Note that the definition of the energy adjustable amount, that is, the influence on the user's indoor environment is within the allowable range is that the illuminance is maintained within the allowable range, for example, when the equipment is lighting. In the case where the equipment is a ventilation fan, for example, it means that the ventilation amount is maintained in an allowable range.

  Therefore, for example, the conditions in the condition storage area 35b may be set according to illuminance or ventilation volume.

(5-7) Modification 1G
The control device 30 does not need to target the entire facility equipment of the property for energy adjustment control, and may execute energy adjustment control for a part thereof. Further, for example, the energy adjustment control may be executed for each type of equipment and for each floor of the property.

(5-8) Modification 1H
The energy calculation unit 36c may calculate an energy adjustable amount for each of a plurality of conditions. For example, as long as the influence on the user's indoor environment is maintained within an allowable range, the energy adjustment control is provided with “energy saving emphasis”, “energy saving / comfort balance”, and “comfort emphasis” as shown in FIG. In addition to the duration of energy adjustment control, conditions are prepared according to the stage. And the energy calculation part 36c calculates the energy adjustable amount which can be adjusted when energy adjustment control is performed according to the conditions according to a step. That is, a plurality of energy adjustable amounts are calculated for each stage. A plurality of energy adjustable amounts and energy prices corresponding to the energy adjustable amounts are output to the output unit 32.

  In this case, the control device 30 further includes a selection unit 36g that selects one condition from a plurality of conditions as shown in FIG.

  For example, the selection unit 36g selects a condition as follows. The user looks at the energy adjustable amount output to the output unit 32 and the corresponding energy price, and selects 1 from “energy saving emphasis”, “comfort emphasis”, and “balance emphasis” and selects the input unit as a selection criterion. 33. The selection unit 36g selects a condition corresponding to the selection criterion input by the user. The adjustment unit 36d performs energy adjustment control under the conditions selected by the selection unit 36g.

  As a result, the user can check the plurality of calculated energy adjustment possible amounts and the corresponding energy prices that can be reduced, select the condition closest to the needs, and execute the energy adjustment control.

  Note that the method by which the selection unit 36g determines the condition is not limited to the above method. For example, instead of the user inputting the selection criterion every time, the selection criterion once input may be used for determining the repetition condition. The selection unit 36g may determine one condition by the following method, for example, instead of or in addition to the input of the user's selection criteria. For example, one condition such that the calculated energy adjustable amount falls within a predetermined value range may be automatically determined by the selection unit 36g. In addition, for example, past driving status stored in the driving status storage area 35a and past energy adjustment control information stored in the control information storage area 35e, expected power consumption, expected energy price, environmental conditions The condition 1 may be determined in consideration of the operating status of the equipment.

Second Embodiment
Next, an energy management system 200 according to the second embodiment will be described (see FIG. 16). The energy management system 200 according to the second embodiment is the same as the energy management system 100 according to the first embodiment except for the configuration of the control devices 230 and 230. Therefore, only the difference between the control process performed by the energy management system 200 and the first embodiment will be described.

(1) Configuration of Each Unit (1-1) Configuration of Control Devices 230 and 230 FIG. 17 shows a schematic configuration diagram of the control devices 230 and 230. Hereinafter, the control device 230 installed in the property A will be described, but the control device 230 installed in the property B has the same configuration.

  The control device 230 includes a communication unit 231, an output unit 232, an input unit 233, a time management unit 234, a storage unit 235, and a control unit 236. Here, 231, 232, 233, and 234 have the same configuration as 31, 32, 33, and 34 of the first embodiment. Therefore, the storage unit 235 and the control unit 236 will be described below.

(1-1-1) Storage unit 235
The storage unit 235 is mainly composed of a hard disk. The storage unit 235 stores a program that can be read and executed by the control unit 236 described later. The storage unit 235 mainly includes an operation status storage area 235a, a condition storage area 235b, a unit price storage area 235c, a candidate time zone storage area 235d, a control information storage area 235e, a cheapest unit price storage area 235f, and a predicted amount storage area. 235g and a predicted price storage area 235h. 235a, 235c, 235d, 235e, 235f, 235g, and 235h have the same configurations as 35a, 35c, 35d, 35e, 35f, 35g, and 35h, respectively. Therefore, the condition storage area 235b will be described below.

(1-1-1-1) Condition storage area 235b
The conditions stored in the condition storage area 235b are conditions related to the pattern of energy adjustment control. The pattern of energy adjustment control is a combination of the execution time of energy adjustment control and the release time of energy adjustment control.

  The condition is used by an energy calculation unit 236c described later to calculate an energy adjustable amount. The adjusting unit 236d described later performs energy adjustment control according to the conditions. The condition is that even if the energy adjustment control is executed using this, the influence on the user's indoor environment, for example, room temperature and humidity is within an allowable range with respect to the set temperature and set humidity, and the user's profit, For example, it is determined in advance so that the energy price and the reduction amount of energy consumption can be as large as possible.

  In the condition storage area 235b, for example, conditions as shown in FIG. 18 are stored. In FIG. 18, a pattern of energy adjustment control that is a condition for the length of the candidate time zone is determined. For example, when the candidate time zone is 120 minutes for the control device, the energy adjustment control is executed for 60 minutes, and then the energy adjustment control is released for 30 minutes. Thereafter, the energy adjustment control is executed again for 30 minutes. The duration of energy adjustment control and the release time of energy adjustment control are determined so as to be unit time in the energy trading market (30 minutes in the present embodiment) or a multiple thereof. However, it is not limited to this.

  Note that the plurality of conditions stored in the condition storage area 35b are not necessarily set for the candidate time zone as shown in FIG. For example, the duration of energy adjustment control, the expected power consumption, the expected energy price, the state value of the indoor environment of the property where the air conditioners 40, 40... Are installed, the external environment, and the operation of the equipment It may be set for at least one of the states.

  Furthermore, the condition does not need to be fixed, and may be updated by the user inputting from the input unit 233. Further, for example, the duration and the number of times of the energy adjustment control and the release time may be changed with respect to the duration time of the energy adjustment control or a plurality of state values.

(1-1-2) Control unit 236
The control unit 236 mainly includes a CPU, a ROM, and a RAM. As shown in FIG. 17, the control unit 236 reads and executes the program stored in the storage unit 235, thereby mainly operating state grasping unit 236a, determination unit 236b, energy calculation unit 236c, and adjustment unit. 236d, a supply company instruction unit 236e, and a prediction unit 236f.

  236a, 236b, 236e, and 236f have the same configuration as 36a, 36b, 36e, and 36f, respectively. Therefore, the energy calculation unit 236c and the adjustment unit 236d will be described below.

(1-1-2-1) Energy calculation unit 236c
The energy calculation unit 236c calculates an adjustable energy amount that can be adjusted when the energy adjustment control is performed according to the conditions in the candidate time zone. The calculation of the energy adjustable amount is executed immediately before the start of the candidate time zone. The condition is a condition stored in the above-described condition storage area 235b.

  In the present embodiment, the energy adjustable amount is calculated as follows.

  First, the energy calculation unit 236c calls the energy consumption amount [kW] per unit time acquired by the driving state grasping unit 236a immediately before calculating the energy adjustable amount from the driving state storage area 235a. After that, the energy calculation unit 236c calculates the energy consumption W3 when the air conditioners 40, 40... Are operated with the energy consumption per unit time in the candidate time zone. Next, an energy consumption amount W4 when energy adjustment control is performed according to the conditions in the candidate time zone is calculated. A difference (W3−W4) between the two energy consumption amounts is calculated as an energy adjustable amount.

  W3 and W4 are each represented by the following equations.

(Formula 4) W3 = w × ΔT
(Formula 5) W4 = Σ (w × (1−k1) × Δtn) + w × (ΔT−ΣΔtn)
Here, w is the energy consumption [kW] per unit time immediately before the candidate time zone, ΔT is the length of the candidate time zone [hr], and Δtn is the continuation of the nth energy adjustment control in the candidate time zone. Time [hr], k1 represents the energy consumption reduction rate [%].

  Note that W4 is not limited to the above calculation method, and may be expressed by the following equation, for example.

(Expression 6) W4 = Σ ((w−Δw) × Δtn) + w × (ΔT−ΣΔtn)
Here, Δw is the energy consumption [kW] adjusted per unit time.

  In the present embodiment, the energy consumption reduction rate k1 [%] and the energy consumption Δw [kW] adjusted per unit time are the state values representing the user's indoor environment even when the energy adjustment control is executed. It is a fixed value determined so as to be within an allowable range. However, it is not necessary to be a fixed value, and k1 and Δw may be values that can be updated by the user through the input unit 33. For example, information stored in the driving situation storage area 35a is used. The value may be updated as appropriate.

  Specifically, the calculation of the energy adjustable amount in the present embodiment will be described by giving a case example. For example, air conditioners 40, 40... Are currently operating, and 100 kW of power is used immediately before the candidate time for energy adjustment control. The energy consumption reduction rate is determined to be 10%, and it is assumed that FIG. 18 is stored as a condition in the condition storage area 235b with respect to the duration of the energy adjustment control. It is assumed that the candidate time zone for energy adjustment control is 2 hours. In this case, energy adjustment control is executed for the first 60 minutes. Thereafter, the energy adjustment control is canceled for 30 minutes, and then the energy adjustment control is executed again for the remaining 30 minutes.

  At this time, W1 = 100 [kW] × 2 [hr] = 200 [kWh] and W2 = (100 [kW] × (1-10%) × (1 + 0.5) [hr] +100 [kW] × (2- (1 + 0.5)) [hr] = 185 [kWh] is calculated, and the energy adjustable amount (W1-W2) = 15 [kWh] is calculated.

  In the present embodiment, similarly to the first embodiment, when the candidate time zone is longer than a predetermined time (for example, 3 hours), the candidate time zone is divided into a plurality of times. Then, for each divided time zone, the energy adjustable amount when energy adjustment control is executed according to the condition is calculated, and the sum is calculated as the final energy adjustable amount.

(1-1-2-2) Adjustment unit 236d
The adjustment unit 236d performs energy adjustment control according to the conditions stored in the condition storage area 235b in the candidate time zone.

  For example, in the case shown in the specific example of the energy adjustable amount, the energy adjustment control is executed to reduce the energy consumption by 10% for the first 60 minutes with respect to the candidate time zone of 2 hours. Thereafter, after the energy adjustment control is canceled for 30 minutes, the energy adjustment control is executed again for the remaining 30 minutes.

  When the candidate time zone is divided when calculating the energy adjustable amount, the same candidate time zone is divided during energy adjustment control as when the energy adjustable amount is calculated. In each divided time zone, energy adjustment control is executed according to conditions.

(2) About the control processing performed with the energy management system 200, since it is the same as that of 1st Embodiment, it abbreviate | omits.

(3) Features The features (4-1) to (4-4) and (4-7) to (4-9) of the first embodiment also apply to this embodiment. In addition, this embodiment has the following features.

(3-1)
In the present embodiment, the conditions used for the energy calculation unit 36c and the adjustment unit 36d are energy adjustment control patterns.

  Here, the energy adjustment control can be executed by changing the pattern of the energy adjustment control.

(4) Modified Examples The gist of modified examples 1A to 1G according to the first embodiment also applies to the second embodiment. Hereinafter, other modifications 2A and 2B will be described.

(4-1) Modification 2A
The energy calculation unit 236c may calculate an energy adjustable amount for each of a plurality of conditions. For example, when the candidate time zone is 120 minutes, a plurality of energy adjustment control patterns are stored in the condition storage area 235b as shown in FIG. 19, and the energy calculation unit 236c calculates the energy adjustable amount for each condition. To do. A plurality of energy adjustable amounts and energy prices corresponding to the energy adjustable amounts are output to the output unit 232.

  In this case, the control device 230 further includes a selection unit 236g that selects one condition from a plurality of conditions as shown in FIG.

  For example, the selection unit 236g calculates the sum of products of the energy adjustable amount and the energy unit price per unit time (30 minutes in the present embodiment) in the energy market over the candidate time zone, and calculates the energy price from the conditions. Select the condition that maximizes the reduction. A specific example will be described below.

  In this specific example, the time when the energy unit price exceeds a predetermined value is determined as the candidate time zone. It is assumed that the energy unit price changes every 30 minutes as shown in FIG. 21 with respect to the candidate time zone of 2 hours. It is assumed that the condition storage area 235b stores the conditions of FIG. Further, it is assumed that the energy adjustable amount for 30 minutes when the energy adjustment control is executed is 5 kWh.

  At this time, the energy adjustment control is executed for 90 minutes and the energy adjustment control is canceled for 30 minutes under the conditions of FIG. 19, so the energy adjustable amount calculated by the energy calculation unit 236c is the same. On the other hand, since the energy unit price fluctuates in the candidate time zone as shown in FIG. 21, the reduction amount of the energy price in the conditions 1 to 3 is 375 yen, 350 yen, and 400 yen, respectively. At this time, the selection unit 236g selects the condition 3 that maximizes the reduction amount of the energy price. The adjustment unit 236d performs energy adjustment control under the conditions selected by the selection unit 236g.

  Instead of the selection unit 236g automatically selecting a condition, the input unit 233 may receive an input as to which condition is selected from the user, and the selection unit 236g may select the condition according to the user's input.

  By accepting input from the user, it is possible to execute energy adjustment control by selecting conditions close to the user's needs.

(4-2) Modification 2B
In the condition storage area 235b, for example, as shown in FIG. 22, conditions relating to both the energy adjustment control pattern and the intensity of the energy adjustment control of the first embodiment may be stored. For example, in FIG. 22, when the candidate time zone is 120 minutes, the driving is performed in the pattern of 60 minutes control-30 minutes control release-30 minutes control. Moreover, the weight of energy adjustment control changes with changes in the outside air temperature.
