Description

  The present invention relates to a control planning method, a control method, and a control device.

  The power supply plans that power companies have traditionally used are plans to adjust the amount of power supply by operating / stopping power generation facilities and power interchange. Normally, demand is assumed to be a predicted value (fixed value). Yes. Further, in recent years, in order to solve the power shortage due to the increase in demand, studies have been started on a technique for maintaining a power supply balance by controlling a device (for example, an air conditioner) on the power consumer (customer) side. Such a technique is called demand response.

With respect to the power supply plan, techniques such as those disclosed in Patent Documents 1 and 2 have been proposed. The technology of Patent Literature 1 relates to cost optimization by systematically performing power generation control on the supply side and power interchange between zones, and the technology of Patent Literature 2 relates to technology for minimizing CO ₂ emissions. Is.

  However, the technologies of Patent Documents 1 and 2 can cope with “variety of temperature tolerance” for each consumer and “diversity of values for reward (customer's profit)” obtained by demand response. Can not. Here, “variety of temperature tolerance” for each consumer means, for example, that you do not want to change the air conditioning temperature setting when there are visitors, or you want to control the air conditioning temperature setting yourself depending on your mood. This means that there are some customers who think that they can always follow the control of the electric power company. Further, “diversity of values for rewards” means that there are consumers who want to acquire a large amount of rewards obtained by demand response and those who think that they may be small.

  In order to deal with such diversity, if the customer is given the right to release control based on demand response, uncertain elements are mixed in the power supply and demand plan, making it difficult to plan the supply and demand plan. Become.

  Hereinafter, an embodiment of an air conditioner control system will be described in detail with reference to FIGS. FIG. 1 schematically shows the configuration of an air conditioner control system 100 according to an embodiment.

  The air conditioner control system 100 is a power supplier (service provider) such as an electric power company or PPS (Power Product Supplier) that controls the air conditioner of each consumer. Response). As shown in FIG. 1, an air conditioner control system 100 includes a control server 10 owned by a service provider, an air conditioner control device 20 installed in each home, office, factory, etc. (hereinafter referred to as “customer”), A smart meter 22 and an air conditioner 24 and an air temperature data providing device 30 are provided. Each of the control server 10, the air conditioner control device 20, the smart meter 22, and the temperature data providing device 30 is connected to a network 40 such as the Internet. The temperature data providing device 30 is a device installed in an organization or company that observes and predicts the weather and temperature, such as the Japan Meteorological Agency and the Meteorological Association. The temperature data providing device 30 provides the control server 10 with temperature data observed at and near the point where the customer exists, and temperature data predicted at and near the point where the customer exists. Send to.

Here, a contract between one of the following two types of services is made between the service provider and the customer regarding the air-conditioner control service (a service for obtaining incentives in cooperation with power demand control). It shall be.
(A) Non-cancelable service This service is a contract made by a consumer who places importance on remuneration, and when the air conditioner 24 is controlled by the service provider, the control cannot be canceled (the temperature setting is changed). It is a contract that cannot be changed.
(B) Cancelable service This service is a contract concluded by a consumer who places importance on comfort, and even when the air conditioner 24 is controlled by the service provider, the control can be canceled (temperature setting) Can be changed).

  The contents, merits, and demerits of each service are summarized in FIG. As can be seen from FIG. 2, (a) a service that cannot be canceled is easy to devise a supply and demand plan from the service provider side, but the remuneration (cost) to be paid to the customer is high. On the other hand, in the case of (b) cancelable service, from the service provider side, the remuneration (cost) to be paid to the customer is reduced, but it is difficult to make a supply and demand plan.

  Returning to FIG. 1, the control server 10 formulates a control plan for the air conditioner 24 of each customer based on various data, and controls the air conditioner 24 based on the control plan. To give instructions.

  FIG. 3 shows a hardware configuration diagram of the control server 10. As shown in FIG. 3, the control server 10 includes a CPU 90, a ROM 92, a RAM 94, a storage unit (HDD (Hard Disk Drive)) 96, a network interface 97, a portable storage medium drive 99, and the like. Each component of the control server 10 is connected to the bus 98. In the control server 10, the CPU 90 executes a program stored in the ROM 92 or the HDD 96 or a program read from the portable storage medium 91 by the portable storage medium drive 99, thereby realizing the functions of the respective units in FIG. The

  FIG. 4 shows a functional block diagram of the control server 10. As shown in FIG. 4, the control server 10 executes a program by the CPU 90, so that the meter data acquisition unit 52, the temperature data acquisition unit 54, the coefficient calculation unit 56, the control plan planning unit 58 as a planning unit, and the control It functions as the execution unit 60. In FIG. 4, the customer temperature DB 72, the collected data DB 74, the coefficient DB 76, the control plan DB 78, and the cancel cover DB 80 stored in the HDD 96 and the like are also illustrated.

  The meter data acquisition unit 52 acquires the power consumption of the air conditioner 24 from the smart meter 22 of each consumer and stores it in the collected data DB 74.

  The temperature data acquisition unit 54 acquires the temperature data (outside temperature) outside the space where the air conditioner of each customer is installed from the temperature data providing device 30 and stores it in the collected data DB 74. Further, the temperature data acquisition unit 54 acquires a predicted temperature for each time (for example, every hour) of the next day from the temperature data providing device 30 and transmits the predicted temperature to the control plan planning unit 58.

  The coefficient calculation unit 56 uses the data stored in the collected data DB 74 to calculate a model coefficient used for making a control plan and stores it in the coefficient DB 76.

  The control planning unit 58 uses the model coefficient stored in the coefficient DB 76, the data stored in the customer temperature DB 72, and the predicted temperature for each time of the next day acquired by the temperature data acquisition unit 54. Thus, a control plan for the next day of the air conditioner 24 of each consumer is made. Note that the control plan drafting unit 58 also considers whether the contract contents of the customer are (a) or (b) in the planning of the control plan. The control plan drafting unit 58 stores the drafted control plan in the control plan DB 78. In addition, the control planning unit 58 uses each of the air conditioners of the customers who are subscribed to the non-cancelable service and the air conditioners of the customers who are subscribed to the cancelable service similar to this (the power suppression amount is similar). Are stored in the cancel cover DB 80 in association with each other.

  Based on the control plan stored in the control plan DB 78, the control execution unit 60 issues an instruction to the air conditioner control device 20 of each consumer in order to control the air conditioner 24 of each consumer. Further, the control execution unit 60 stores the control temperature of the air conditioner 24 (the temperature in the space where the air conditioner is installed (room temperature)) in the collected data DB 74. Moreover, the control execution part 60 detects whether the consumer who has concluded the contract of the cancelable service canceled the control by the control execution part 60 based on the state of the air-conditioner control apparatus 20. And control execution part 60 performs additional control of air conditioner 24 of another consumer based on cancellation cover DB80, when cancellation is detected.

  The detailed processing of each unit and the detailed data structure of each DB will be described later.

  Returning to FIG. 1, the air conditioner control device 20 is a device such as a thermostat capable of changing the settings of the air conditioner 24. As the air conditioner control device 20, various devices such as a device that performs control via a home router and a device that performs control via a smart meter 22 can be employed.

  The smart meter 22 is a power meter having a communication function, detects the power consumption of the air conditioner 24, and transmits the detection result to the control server 10 (meter data acquisition unit 52). It is assumed that the air conditioner control device 20 and the smart meter 22 are installed near the air conditioner 24 of each consumer by the service provider.

  The air conditioner 24 is a device that performs air conditioning inside a space (room, office, factory, etc.) of a consumer. In FIG. 1, it is described that each consumer has one air conditioner 24. However, the present invention is not limited to this, and the consumer may have a plurality of air conditioners 24. In this case, a plurality of air conditioner control devices 20 and smart meters 22 may be installed corresponding to the plurality of air conditioners 24.

  Next, the process (particularly the process of the control server 10) of the air conditioner control system 100 configured as described above will be described in detail. In the following, the control when the air conditioner 24 performs the cooling function (mainly in summer) will be described.

(Assumption)
In the contract for receiving the air conditioning control service, the customer declares to the service provider the room temperature (H _{p, m} ) that he considers optimal and the upper limit of the allowable temperature (H _{p, m} + n _m ). Shall. For example, when H _{p, m} is 27 (° C.) and _nm is 3 (° C.), the indoor temperature that the consumer considers optimal is 27 (° C.), and the allowable indoor temperature is 30 (° C.). become. Note that the subscript m means an air conditioner ID allocated to a customer's air conditioner for each service. In the following, when any one of the air conditioners 24 is indicated, it is also expressed as “air conditioner m”.

The service provider stores the reported data in the customer temperature DB 72 shown in FIG. In the customer temperature DB 72, as shown in FIG. 5, “air conditioner ID (cancelable service air conditioner ID, cancelable service air conditioner ID)”, “optimum room temperature (H _{p, m} )”, “Allowable temperature difference (n _m )” is stored in an associated state. The control server 10 controls each air conditioner within a temperature range (H _{p, m} or more, H _{p, m} + _nm or less) stored in the customer temperature DB 72.

  In addition, the service provider installs the air conditioner control device 20 and the smart meter 22 at the customer who has applied, and connects each device to the air conditioner 24.

  In a state where these processes and operations are completed, the control server 10 executes a process according to the flowchart of FIG. 6 every other day.

  In the process of FIG. 6, first, in step S <b> 100, the control planning unit 58 determines whether or not the cancelable type suppression amount is larger than the cancelable type suppression amount. Here, the “cancelable non-cancellation suppression amount” means the maximum electric energy that can be suppressed when all the air conditioners of customers who have subscribed to the noncancelable service are controlled. The “cancellable suppression amount” means the maximum amount of power that can be suppressed when all the air conditioners of the customers who have subscribed to the cancelable service are controlled. Therefore, the control plan drafting unit 58 calculates and compares the cancelable suppression amount and the cancelable suppression amount. FIG. 7A schematically illustrates an example in which the determination in step S100 is affirmed, and FIG. 7B schematically illustrates an example in which the determination in step S100 is denied. Is shown in

(When judgment of step S100 is affirmed)
If the determination in step S100 is affirmative, pre-planning preparation processing is executed in step S102. In the pre-planning preparation process in step S102, a process according to the flowchart of FIG. 8 is executed.

  In the process of FIG. 8, first, a model coefficient calculation process is executed in step S200. In the model coefficient calculation process of step S200, a process according to the flowchart of FIG. 9 is executed.

  In the model coefficient calculation process of FIG. 9, first, in step S <b> 10, the meter data acquisition unit 52 acquires power consumption from each smart meter 22 and stores it in the collected data DB 74. Here, the collected data DB 74 has a data structure as shown in FIG. Specifically, as shown in FIG. 10, the collected data DB 74 includes “set temperature (H)”, “temperature (TOUT)”, and “power consumption (E)” for each air conditioner m and “date and time”. Is a database that summarizes Therefore, the meter data acquisition unit 52 inputs the acquired power consumption in the column of the date and time corresponding to “power consumption (E)” in the collected data DB 74 in step S10.

  Next, in step S12, the temperature data acquisition unit 54 acquires the outside temperature of the place where each air conditioner 24 is installed from the temperature data providing device 30, and stores it in the collected data DB 74 ("Temperature (TOUT)" column). To do.

  Next, in step S14, the control execution unit 60 stores the set temperature (that is, the room temperature) of each controlled air conditioner 24 in the collected data DB 74 (column of “set temperature (H)”).

  Next, in step S16, the meter data acquisition unit 52 (or the temperature data acquisition unit 54 / control execution unit 60) stands by until a predetermined time elapses. The “predetermined time” in this case is a predetermined data acquisition interval (for example, one hour). If the determination in step S16 is affirmative, the process proceeds to step S18.

  In step S18, the coefficient calculation unit 56 determines whether or not the counting period has elapsed. The “aggregation period” in this case is a predetermined data aggregation period (for example, one week) for calculating the model coefficient. If the determination is negative, the process returns to step S10, and the processes and determinations of steps S10 to S18 are repeated. That is, data is continuously accumulated in the collected data DB 74. On the other hand, if the determination in step S18 is affirmative, the process proceeds to step S20.

When the process proceeds to step S20, the coefficient calculation unit 56, based on the data collected data DB 74, and calculates the model coefficients k _m0, k _m1, k _m2 per air conditioner is stored in the coefficient DB 76.

Here, in step S20, the coefficient calculation unit 56 uses the outside air temperature (TOUT) and the room temperature (H) as explanatory variables, and uses the power consumption E _{m, TOUT, H} of the customer's air conditioner m as an explained variable. This is represented by the linear form (model) of Equation (1). The coefficient calculating unit 56 uses the data collected by the repetition of steps S10 to S14 (data collected data DB 74), by multiple regression analysis, to determine the value of the model coefficients k _m0, k _m1, k _m2 .

  In the present embodiment, focusing on the fact that there is a strong correlation between the outside air temperature and the power consumption of the air conditioner, the line form of the above equation (1) is used.

Coefficient calculating section 56 stores the model coefficients k _m0, k _m1, k _m2 of each air-m determined from the above equation (1) to the coefficient DB 76. Here, as shown in FIG. 11, the coefficient DB 76 can register model coefficients _km0 , _km1 , and _km2 in association with each air conditioner ID (= m).

In the above, are we able to calculate the model coefficients for separately for air conditioning _{m k m0, k m1, k} m2 , even if air conditioning of the same model, same outside air temperature, even though the setting temperature, air conditioning This is because the power consumption of the air conditioner varies due to the structure of the room where the air conditioner is installed.

As described above, the calculation of model coefficients k _m0, k _m1, k _m2 is performed in step S20, all the processing in FIG. 9 is completed, the process proceeds to step S202 in FIG. 8.

  If transfering it to step S202 of FIG. 8, the control plan creation part 58 will extract the air conditioner i of the consumer who has subscribed to the cancelable service. Next, in step S204, the air conditioner of the customer who subscribes to the non-cancelable service similar to the air conditioner i of the customer who subscribes to the cancelable service is specified. Specifically, the control planning unit 58 calculates the following equation (2) for the air conditioner i of the customer who has subscribed to the cancelable service.

E ¹ _{m, TOUT, H} is the power consumption of the air conditioner m of the customer who has subscribed to the non-cancellable service, and E ² _{i, TOUT, H} has subscribed to the cancelable service. This is the power consumption of the air conditioner i of the customer. In the following, it is assumed that the number of subscribers of the non-cancellable service is N1, and the number of subscribers of the cancelable service is N2.

  The control planning unit 58 performs the calculation of the above equation (2) for all the air conditioners (the number of subscribers N1) of customers who have subscribed to the non-cancellable service. As a result, a table as shown in FIG. 12A is generated.

  Here, the calculation result of FIG. 12A shows the difference in power consumption between the air conditioner i of the customer who has subscribed to the cancelable service and the air conditioner of the customer who has subscribed to the cancelable service. The sum of absolute values. Therefore, the air conditioner of the customer who has subscribed to the non-cancellable service with a small calculation result value means that the power consumption is close to that of the air conditioner i.

  Note that the control planning unit 58 associates the air conditioner ID of the air conditioner i with the air conditioner ID of the air conditioner of the consumer who subscribes to the closest (similar) non-cancelable type of power consumption. It is stored in the cancel cover DB 80 shown in b). That is, in step S204, it can be said that the air conditioner of the customer who subscribes to the non-cancelable service with the power suppression amount similar to the air conditioner of the customer who subscribes to the cancelable service is extracted and associated.

  Next, when the process proceeds to step S206 in FIG. 8, the control planning unit 58 determines whether or not the air conditioners of all cancelable service customers have been extracted. When judgment here is denied, it returns to step S202. When the process returns to step S202, an unextracted air conditioner is extracted (S202), and the air conditioner of the non-cancellable service consumer with the closest power consumption is identified by performing the above equation (2). (S204). In step S204, the air conditioner of the non-cancellable service customer already stored in the cancel cover DB 80 is not identified again (excluded from the calculation of the above equation (2)). To do).

  Then, when the determination in step S206 is affirmed, the process in FIG. 8 is terminated, and the process proceeds to step S104 in FIG. Note that at the stage of shifting to step S104, all the columns of the cancel cover DB 80 in FIG. 12B are filled.

  In step S104 of FIG. 6, the control plan planning process is executed according to the flowchart of FIG. The control plan drafting process is a process in which the control plan drafting unit 58 drafts a control plan for each air conditioner on the next day. In this case, the control planning unit 58 sets the air conditioner (part (3) in FIG. 14) of the customer who has subscribed to the cancelable service as the control target device. The control planning unit 58 is associated with the air conditioner of the customer who has subscribed to the cancelable service among the air conditioners of the customer who has subscribed to the cancelable service (stored in the cancel cover DB 80). ) Demand for subscribing to a non-cancellable service that is not associated with the air conditioner of a customer subscribing to a cancelable service, excluding the air conditioner (part (1) in FIG. 14) from the controlled device Assume that the home air conditioner (part (2) in FIG. 14) is the control target device.

  In the process of FIG. 13, first, in step S30, the process waits until a predetermined time is reached. In this case, the “predetermined time” is a time after a day before a bid is placed in the power trading market and before a power generation movable preparation for the next day.

  When the determination in step S30 is affirmed and the process proceeds to step S32, the control plan drafting unit 58 acquires a predicted temperature (PTOUTt) for each time t (for example, every hour) of the next day from the temperature data providing device 30.

Then, in step S34, the control planner 58, model coefficients _{(k m0, k m1, k} m2), the predicted temperature (PTOUTt), using the next day electricity demand forecast and the like, each day of the time t of each air-conditioned The set temperature is calculated and a control plan for each air conditioner is drawn up. Hereinafter, the process of step S34 will be described in detail.

  In step S34, the control plan drafting unit 58 calculates the objective function shown in the following equation (3). This objective function provides services for control of air conditioners of customers who have subscribed to non-cancelable services that are not stored in the cancel cover DB 80 and air conditioners of customers who have subscribed to cancelable services. It is an objective function for drafting an air conditioner control plan that optimizes the profits of consumers.

  Note that the objective function of the following equation (3) requires the constraint (1) of the equation (4).

Each character formula of the above formulas (3) and (4) is defined as follows.
NA1: Number of subscribers (stored in the cancellation cover DB 80) of customers who have canceled the cancelable service among the customers who have subscribed to the cancelable service (see FIG. 14)
Δea2 _{j, t} [kwh]: Demand suppression amount at time t of air conditioner j of a customer who has subscribed to the non-cancellable service to be planned (see FIG. 14)
NA2: Number of subscribers of customers who have subscribed to the non-cancellable service to be planned (see Figure 14)
Δeb _{j, t} [kwh]: Demand suppression amount at time t of air conditioner j of a customer who has subscribed to a cancelable service (see FIG. 14)
NB: Number of customers who have subscribed to the cancelable service (see Figure 14)
DA1 _{j, t} [kwh]: Predicted demand at the time t of the air conditioner of the customer who covers the cancellation of the cancelable service among the customers who have subscribed to the cancelable service
DA2 _{j, t} [kwh]: Expected demand at the time t of the air conditioner of the customer who has subscribed to the non-cancellable service to be planned
DB _{j, t} [kwh]: Expected demand at the time t of air conditioners of customers who have subscribed to a cancelable service
p _{i, t} [kwh]: Power supplied by power supply unit i at time t (procurement from electric power company, private power generation, etc.)
CP _i [Cost / kwh]: Unit cost of power cost for power generation by power supply unit i
PD [Fee / kwh]: Unit price per kwh of electricity sales
M _a [Cost / kwh]: Incentive paid to consumers who have subscribed to non-cancellable services for demand suppression (costs from the service provider side) (see Figure 2)
M _b [Cost / kwh]: Incentive paid to consumers who have subscribed to a cancelable service for demand restraint (cost from the service provider side) (see Figure 2)
In addition, Δea1 _{j, t} [kwh] in FIG. 14 covers the cancellation of the cancelable service among the consumers who have subscribed to the cancelable service (stored in the cancellation cover DB 80). It means a demand suppression amount (power suppression amount) at time t.

  That is, the first term of the formula (3) indicates the power cost for generating the power supplied by the power supply unit, and the second and fourth terms are paid by the service provider to the demand-suppressing consumers. The cost represents the cost, and the third term and the fifth term represent the profit that the service provider obtains from the power sale. Note that when solving the above optimization problem, lowercase letters are variables and uppercase letters are constants.

Here, in order for the control plan drafting unit 58 to solve the above objective function and to formulate a control plan for the next day air conditioner, Δea1 _{j, t} , Δea2 _{j, t} , Δeb _{j, t} in the state of the air conditioner 24. (However, Δea1 _{j, t} is not used in the above equation (3)). Hereinafter, this point will be described.

First, the state of the air conditioner m at time t is represented by state variables a [0] _{m, t} , a [1] _{m, t} , a [2] _{m, t} ,..., A [n _m ] _{m, t} . The state variables a [0] _{m, t} , a [1] _{m, t} , a [2] _{m, t} ,..., A [n _m ] _{m, t} have a value of 0 or 1. The meanings of the values 0 and 1 are as follows. The value H _{p, m} and the value _nm are values of the difference between the optimum indoor temperature and the allowable temperature stored in the customer temperature DB 72 of FIG.
a [0] _{m, t} is 1 when the set temperature of the air conditioner m is (H _{p, m} ) (others are 0).
a [1] _{m, t} is 1 when the set temperature of the air conditioner m is (H _{p, m} + 1) (others are 0).
...
a [n _m ] _{m, t} is 1 when the set temperature of the air conditioner m is (H _{p, m} + n _m ) (others are 0).

The set temperature of the air conditioner m is changed once per unit time (1 hour in the present embodiment) in order to prevent the set temperature from changing abruptly. FIG. 15 is a diagram illustrating an example of a change in a state variable (representing a set temperature) with respect to time (horizontal axis). In FIG. 15, for example, at time t = 4, a [1] _{m, t} is 1, so when time t = 4, the set temperature is set to H _{p, m} + 1 (° C.). Show. In the present embodiment, it is assumed that the following restrictions are added so that the state of the air conditioner transitions without contradiction as shown in FIG.

  Since the set temperature of the air conditioner m needs to be determined to be one at a certain time, the following constraints (2), (3) (the following equation (2) are set so that only one state variable at a certain time has the value “1”. 5) and (6)) are added.

Further, when the set temperature at time t is H _{p, m} , at time t + 1, the set temperature H _{p, m} is maintained or limited to changing to the set temperature H _{p, m} +1. The following constraint (4) (following equation (7)) is added.

Further, when the set temperature at time t is H _{p, m} + k, at time t + 1, the set temperature H _{p, m} + k is maintained, or the set temperature H _{p, m} + k + 1 is changed to the set temperature. The following constraint (5) (the following formula (8)) is added so that it is limited only to the change to H _{p, m} + k−1.

ただし、１≦ｋ≦ｎ−１であるとする。

However, it is assumed that 1 ≦ k ≦ n−1.

Further, when the set temperature at time t is H _{p, m} + n _m , at time t + 1, the set temperature H _{p, m} + n _m is maintained or the set temperature H _{p, m} + n _m −1 is reached. The following constraint (6) (the following formula (9)) is added so that it is limited only to the change.

  With the constraints (4) to (6), it is possible to represent a state change in which the temperature state of the air conditioner is changed by 1 ° C. per unit time (1 hour in the present embodiment).

By defining the state variables of the air conditioner as described above and giving the constraints (1) to (6), the demand power suppression amounts Δea1 _{j, t} , Δea2 _{j, t} , Δeb _{j, t} of each air conditioner at time _t Can be represented by the following formulas (10) to (12).

Here, PTOUTt is the predicted temperature at time t of the next day acquired in step S32. Further, E is an expression obtained by substituting the model coefficients k _m0, k _m1, k _m2 in FIG. 11 in the above equation (1). Of Δea1 _{j, t} , Δea2 _{j, t} and Δeb _{j, t} expressed by these equations (10) to (12), Δea2 _{j, t} and Δeb _{j, t} are substituted into the objective function of the above equation (3). Then, by solving the optimization problem using the mixed integer programming method, the state variable of the air conditioner for the next day can be planned, and the air conditioner control plan can be made. That is, the control plan drafting unit 58 can obtain an air conditioner control plan as shown in FIG. 15 for each air conditioner by solving the objective function described above.

  Returning to FIG. 13, when proceeding to the next step S <b> 36, the control plan drafting unit 58 stores the air conditioner control plan in the control plan DB 78 (see FIG. 16). The control plan DB 78 in FIG. 16 stores a control plan for each air conditioner. When the process in FIG. 13 is completed as described above, the process proceeds to step S106 in FIG.

  In step S <b> 106 of FIG. 6, the control execution unit 60 controls each air conditioner based on the air conditioner control plan stored in the control plan DB 78. In this case, the control execution unit 60 subscribes to the air conditioner of the customer who has subscribed to the cancelable service and the cancelable service that is not associated with this (not stored in the cancel cover DB 80). It will control the customer's air conditioner.

  Next, in step S108, the process waits until cancellation occurs. In this case, when the control execution unit 60 detects that the air conditioner controlled by the control execution unit 60 is not operating as controlled, the process proceeds to step S110.

  If transfering it to step S110, the control execution part 60 will suppress the electric power of the consumer who has subscribed to the non-cancelable service which was excluded from the plan. Specifically, the control execution unit 60 refers to the cancellation cover DB 80 (FIG. 12B), and the customer who has subscribed to the non-cancelable service associated with the canceled air conditioner. The air conditioner is specified, and control of the specified air conditioner is started. In this case, the control execution unit 60 controls the specified air conditioner based on the canceled air conditioner control plan.

  Next, in step S112, the control execution unit 60 determines whether it is an end time. If the determination here is negative, the process returns to step S108, but if the determination here is affirmative, the entire process of FIG. 6 is terminated.

  As described above, the control execution unit 60 executes the processes of steps S106 to S112, so that even if a customer who subscribes to the cancelable service cancels the control, the electric power generated by the cancellation The reduction in the amount of restraint can be covered by an air conditioner similar to the canceled customer's air conditioner (the air conditioner of the customer who has subscribed to the non-cancellable service). As a result, the power suppression amount can be maintained substantially constant.

(If the determination in step S100 is negative)
Next, the case where the determination in step S100 of FIG. 6 is negative will be described. In addition, the case where the determination of step S100 is denied means the case where the cancellation impossible type | mold suppression amount is below a cancelable type | mold suppression amount as FIG.7 (b).

  If the determination in step S100 is negative and the process proceeds to step S114, a pre-planning preparation process is executed. In the process of step S114, the process of FIG. 17 is performed. In the process of FIG. 17, first, when the coefficient calculation unit 56 performs the model coefficient calculation process (FIG. 9) in step S200, in step S202 ′, the control plan drafting unit 58 determines the Extract air conditioner i.

  Next, in step S204 ', the control planning unit 58 identifies a customer air conditioner of a cancelable service similar to the customer air conditioner i of the cancel impossible service. In this case, the control planning unit 58 performs the calculation of the above equation (2) for all the air conditioners (the number of subscribers N2) of the customers who have subscribed to the cancelable service. As a result, a table as shown in FIG. 18A is generated.

  Here, the calculation result of FIG. 18A shows the difference in power consumption between the air conditioner i of the customer who has subscribed to the cancelable service and the air conditioner of the customer who has subscribed to the cancelable service. The sum of absolute values. Therefore, the air conditioner of the customer who has subscribed to the cancelable service with a small value of the calculation result means that the power consumption is close to that of the air conditioner i.

  Note that the control planning unit 58 associates the air conditioner ID of the air conditioner i with the air conditioner ID of the air conditioner of the consumer who subscribes to the cancelable service with the closest power consumption, as shown in FIG. Store in the cancel cover DB 80.

  Returning to FIG. 17, when the process proceeds to step S <b> 206 ′, the control planning unit 58 determines whether or not the air conditioners of all non-cancellable services are extracted. If the determination here is negative, the process returns to step S202 '. When the process returns to step S202 ′, an unextracted air conditioner is extracted (S202 ′), and the air conditioner of the cancelable service consumer with the closest power consumption is calculated by calculating the above equation (2). Specify (S204 ′). In step S204 ′, the air conditioner of the cancelable service customer already stored in the cancel cover DB 80 is not identified again (excluded from the calculation of the above equation (2)). And).

  Then, when the determination in step S206 'is affirmed, the process in FIG. 17 is terminated, and the process proceeds to step S116 in FIG. It should be noted that all the columns in FIG. 18B are filled in at the stage of proceeding to step S116.

  When the process proceeds to step S116 in FIG. 6, the control planning process is executed in the same manner as in step S104 described above (FIG. 13). In this case, among the air conditioners of the customers who have subscribed to the cancelable service, the control plan is drawn up only by the air conditioners (part (1) in FIG. 19) stored in FIG. Become. Therefore, in step S116, the objective function is expressed by the following equation (13), and instead of the constraint (1) of the above equation (4), the following constraints (1) ′, (1) ”(the following equation (14) ), (15)) is required.

  Other processes are the same as in step S104.

  Next, in step S118 of FIG. 6, the control execution unit 60 performs air-conditioner control based on the control plan DB 78 as in step S106.

  Next, in step S120, the control execution unit 60 waits until cancellation occurs. In this case, when the control execution unit 60 detects that the air conditioner controlled by the control execution unit 60 is not operating as controlled, the process proceeds to step S122.

  After shifting to step S122, the control execution unit 60 uses the air conditioner (control) that has not been controlled yet to the air conditioner (part (2) in FIG. 19) of the customer who has subscribed to the cancelable service that has been excluded from the plan. However, it is determined whether or not there are canceled air conditioners and air conditioners other than the currently controlled air conditioner). When judgment here is affirmed, it transfers to step S124. In step S124, the control execution unit 60 extracts the air conditioner that is most similar to the air conditioner for which control has been canceled (the closest power suppression amount) from the air conditioners of the customers who have subscribed to the cancelable service, The extracted air conditioner is controlled (additional control). When extracting the air conditioner most similar to the canceled air conditioner, for example, the air conditioner most similar to the calculated result of the canceled air conditioner is extracted from the calculation results of the table of FIG. Good.

  On the other hand, if the determination in step S122 is negative, that is, an uncontrolled air conditioner is included in an air conditioner (part (2) in FIG. 19) of a customer who has subscribed to the cancelable service that has been excluded from the plan. If it does not already exist, the control execution unit 60 proceeds to step S126.

  After shifting to step S126, the control execution unit 60 extracts an air conditioner similar to the canceled air conditioner from the air conditioners (part (3) in FIG. 19) of the customer who has subscribed to the non-cancellable service. Control (additional control). In this case, the cancellation cover DB 80 shown in FIG. 18B may be used for extracting similar air conditioners. That is, if the cancel cover has been repeated, the air conditioner of the customer who has subscribed to the non-cancelable type service associated with the air conditioner that was initially controlled by going back to repeat the cover. Is the control target.

  When the process of step S124 or step S126 ends, the process proceeds to step S128, and the control execution unit 60 determines whether it is the end time. If the determination here is denied, the process returns to step S120, but if the determination here is affirmed, the entire process of FIG. 6 is terminated.

  As described above, in the control execution unit 60, the process of steps S114 to S128 is performed, so that even if the customer who has subscribed to the cancelable service cancels the control, the cancelable service Since the air conditioner of the customer who is subscribed to the customer or the customer who is subscribed to the non-cancellable service is controlled, the power suppression amount can be maintained almost constant. In this case, since the customer who has subscribed to the cancelable service is preferentially controlled, the cost of the service provider can be reduced.

  As described above in detail, according to the control server 10 of the present embodiment, the control planning unit 58 controls the air conditioners 24 of all customers who are subscribed to a non-cancellable service in which the control of the air conditioners 24 cannot be canceled. The power suppression amount (cancellation-cancellation suppression amount) is the power suppression amount (cancellation-cancellation suppression when all the customers who are subscribed to the cancelable service that can cancel the control of the air conditioner 24 are controlled. (S100), and if the result of the determination is that the non-cancellable type suppression amount is larger, each of the power suppression amounts of the air conditioners of the customers who are subscribing to the cancelable service Extract and associate air conditioners of customers who are subscribed to non-cancelable services, which are similar to the amount of power suppression. Stored in Rukaba DB80) (S102 (S204)). The control planning unit 58 then associates the air conditioner of the consumer who has subscribed to the cancelable service with the customer who has subscribed to the non-cancelable service that is not associated (not stored in the cancel cover DB 80). A control plan is drafted using the air conditioner as a control target device. Thereby, in this embodiment, even if a customer who has subscribed to the cancelable service cancels the control of the air conditioner, the reduction in the amount of power suppression caused by the cancellation is reduced to the demand subscribed to the cancelable service. It can be covered by the control of the air conditioner of the house (the associated customer). Therefore, in this embodiment, it is possible to eliminate the uncertainty of power suppression due to the cancellation of control. As described above, in the present embodiment, a reliable power supply and demand plan can be established even if services (cancellation-cancellation service and cancellation-cancellation service) corresponding to the diversity of consumers are provided.

  Moreover, in this embodiment, the control plan drafting part 58 is a customer who has subscribed to the non-cancelable type service when the non-cancelable type suppression amount is equal to or less than the cancelable type suppression amount as a result of the determination in step S100. The air conditioner of the customer who subscribes to the cancelable service of the power suppression amount similar to each of the power suppression amount of each air conditioner is extracted and matched, and the customer who has subscribed to the associated cancelable service Develop a control plan using the air conditioner as the control target device. Thereby, in this embodiment, even if the control of the air conditioner to be controlled is canceled, the air conditioner of the customer who has subscribed to the cancelable service that is not the control target is used to reduce the power suppression amount caused by the cancellation. Or it can cover by control of the air conditioner of the consumer who is subscribed to the non-cancellable service (the associated customer). Therefore, also from this point, it is possible to eliminate the uncertainty of power suppression due to the cancellation of the control. In this case, when the control of the air conditioner is cancelled, the control execution unit 60 first reduces the amount of power suppression caused by the cancellation. The air conditioner of the customer who subscribes to the cancelable service that is not the control target. If the air conditioner of the customer who has subscribed to the cancelable service cannot cover the air conditioner alone, the air conditioner of the customer who has subscribed to the cancelable service is covered. Thereby, it is possible to perform control for power suppression with certainty in consideration of the cost of the service provider.

In addition, according to the present embodiment, the coefficient calculation unit 56 performs each of the data based on the temperature in the space in which each of the plurality of air conditioners 24 is installed, the temperature outside each space, and the power consumption data of each air conditioner 24. A model coefficient ( _{km 0} , _{km 1} , _{km 2} ) for calculating the relationship between the temperature inside the air conditioner, the outside air temperature, and the power consumption is calculated, and the control planning section 58 is calculated by the coefficient calculation section 56. Model coefficient ( _km0 , _km1 , _km2 ) of each air conditioner, predicted outside temperature for each time t on the next day, optimum air conditioner temperature ( _{Hp, m} ) set in advance and allowable range ( _nm ) Are used to determine the set temperature of each air conditioner at each time of the next day so that the objective function related to power (equation (3), equation (13)) becomes the minimum value, and a control plan for each air conditioner is drawn up. . Thereby, in this embodiment, while being able to maintain a consumer's comfort by setting the preset temperature of an air-conditioner to be in the preset allowable range, an objective function (formula (3), By formulating a control plan for each air conditioner so that (13)) becomes the minimum value, the power supply to the consumer can be adjusted so as to minimize the cost of the service provider (electric power company, etc.). . That is, it is possible to formulate an air conditioner control plan that achieves both profit optimization on the service provider side and comfortable living at a room temperature comfortable for consumers.

  Further, in the present embodiment, the control planning unit 58 determines the set temperature of each air conditioner on the next day so that the objective function becomes the minimum value while limiting the change in the set temperature of each air conditioner. Thereby, it can suppress that a consumer's comfort is impaired by the rapid change of the preset temperature (namely, indoor temperature) of an air-conditioner.

In the above embodiment, the objective function considering the cost of the service provider is used as the objective function. However, the objective function is not limited to this, and an objective function considering the CO ₂ emission amount may be used. In this case, a control plan may be made so that the value of the objective function is minimized. Moreover, it is good also as using the objective function regarding another electric power.

  In addition, although the said embodiment demonstrated the case where the control server 10 controls the air conditioner 24, it is good also as controlling not only this but the apparatus which requires another electric power.

  The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the processing apparatus should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing contents can be recorded on a computer-readable recording medium.

  When the program is distributed, for example, it is sold in the form of a portable recording medium such as a DVD (Digital Versatile Disc) or a CD-ROM (Compact Disc Read Only Memory) on which the program is recorded. It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. Further, each time the program is transferred from the server computer, the computer can sequentially execute processing according to the received program.

  The above-described embodiment is an example of a preferred embodiment of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention.
