By the way, in response to the power consumption consumed by each of the plurality of consumers who own the above-mentioned heat pump type water heater, the electric power company or the company that mediates between the electric power company and the consumer responds to the peak of the total daily power consumption. It is important to manage. Electric power companies manage multiple generators (for example, generators that generate thermal power), but some generators operate only during a short period of time, including peaks during the day, depending on trends in power consumption. exist. As a general rule, the generator does not operate in the time zone other than the short time zone, so that the cost of maintaining and managing the generator having a low operating rate is wasted.

On the other hand, since the power consumption is low in the nighttime such as midnight and midnight, there is a margin in the power supply capacity that the generator can tolerate. Therefore, if the heat pump is heated by using the electric power supplied at night, the peak of the total power consumption during the day can be reduced. However, even in the nighttime, when there is a margin compared to the peak of total power consumption, it is required to further reduce the number of generators having a low operating rate to further reduce the above cost.

Therefore, in one aspect, it is an object to provide a scheduling program, a scheduling method, a scheduling device, and a scheduling system that can schedule information on the power consumption of each consumer required for boiling a heat pump within an allowable range of a generator. And.

In one embodiment, the scheduling program stores power consumption information in which the magnitude and time of power consumption required for boiling the heat pump are associated with each individual or corporate consumer who owns the heat pump type water heater . The first storage unit stores the demand forecast information representing the demand forecast of the power consumed by the device other than the heat pump, the second storage unit stores the supply capacity information representing the supply capacity of the generator that supplies the power. With reference to the third storage unit, the power consumption information of each consumer is assigned within a specific range for specifying the allowable power consumption based on the demand forecast information and the supply capacity information, and the total of the power consumption information. Power consumption information related to the difference between When the distribution value after the movement is repeatedly moved and becomes equal to or higher than the distribution value before the movement, the predetermined information is transmitted as the operation plan information of the heat pump, the processing is executed by the computer, and the predetermined information is the demand for each demand. It is characterized in that the power consumption information of the house is included together with the boiling start time after the movement of the heat pump and the boiling end time after the movement .
Further, in one embodiment, the scheduling program includes a first storage unit that stores power consumption information in which the magnitude and time of power consumption required for boiling the heat pump are associated with each customer, and a device other than the heat pump. The demand is referred to by a second storage unit that stores demand forecast information that represents a demand forecast of power to be consumed and a third storage unit that stores supply capacity information that represents the supply capacity of the generator that supplies the power. Power consumption information of each consumer is assigned within a specific range for specifying the allowable power consumption based on the forecast information and the supply capacity information, and the power consumption information transfer regarding the difference between the total of the power consumption information and the specific range. If the distribution value before and after the movement is calculated and the distribution value after the movement is less than the distribution value before the movement, the power consumption information of the movement target is repeatedly moved in the direction of time, and the distribution value after the movement is before the movement. When it becomes equal to or more than the dispersion value of, the predetermined information is transmitted as the operation plan information of the heat pump, the processing is executed by the computer, and the predetermined information is the power consumption information of each consumer after the movement of the heat pump. In the process of allocating the power consumption information, which is included together with the boiling start time and the boiling end time after the movement, the power consumption information allocation order of each consumer is in descending order of the average value of heat dissipation loss up to the day before the allocation date. Is determined, and the power consumption information of each consumer is allocated based on the allocation order.

The information processing unit 250 can be realized by, for example, the CPU 200A and the RAM 200B described above.

The power consumption storage unit 210 stores power consumption information. Specifically, as shown in FIG. 4A, the power consumption storage unit 210 manages a plurality of power consumption information by the first table T1. The power consumption information is information in which the boiling power consumption and the boiling time are associated with each consumer. As described above, the boiling power consumption represents the magnitude of the power consumption required for boiling the heat pump water heater 300. In particular, boiling power consumption represents a predicted value of the magnitude of power consumption. In the present embodiment, watts (W) are used as the unit of the predicted value, but the unit of the predicted value is not particularly limited. On the other hand, the boiling time represents the time required for boiling the heat pump water heater 300 as described above. In particular, the boiling time represents a predicted value of the time required for boiling. In the present embodiment, time is used as the unit of the predicted value, but the unit of the predicted value is not particularly limited and may be, for example, minutes.

As shown in FIG. 4B, each power consumption information can be schematically represented by the magnitude of the boiling power consumption and the length of the boiling time. For example, the power consumption information of the consumer A can be represented by two-dimensional information specified based on the boiling power consumption "1000 (W)" and the boiling time "3 (hours)". The same applies to consumer B, consumer C, and consumer D as well as consumer A. Although the details will be described later, the power consumption information is stored in the power consumption storage unit 210 by the information processing unit 250, and the information processing unit 250 acquires the power consumption information from the power consumption storage unit 210 and executes various processes. ..

The demand forecast storage unit 220 stores the demand forecast information. Specifically, as shown in FIG. 5, the demand forecast storage unit 220 manages the demand forecast of the power consumption (or demand power) consumed (or requested) by the equipment other than the heat pump water heater 300 in chronological order. For example, the demand forecast storage unit 220 may manage the demand forecast in predetermined time units (for example, in 30-minute units). Further, in FIG. 5, the demand forecast storage unit 220 manages the daily demand forecast, but the demand forecast for a plurality of days may be managed for each day, or the demand forecast for one month may be managed. .. Here, as equipment other than the heat pump water heater 300, for example, there are a storage battery, an induction heating (IH) cooker, and the like. Further, as shown in FIG. 5, during a predetermined time zone such as from 11:00 pm (23:00) on the current day to 7:00 am on the next day, the late-night charge, which is cheaper than the daytime charge for power consumption, is applied. It is a belt. The demand forecast information is stored in the demand forecast storage unit 220 by the information processing unit 250, and the information processing unit 250 acquires and uses the demand forecast information from the demand forecast storage unit 220.

The supply capacity storage unit 230 stores the supply capacity information. Specifically, as shown in FIG. 6, the supply capacity storage unit 230 manages a plurality of supply capacity information by the second table T2. The supply capacity information includes the upper limit of the power that can be supplied by one or a plurality of generators as the supply capacity. For example, the upper limit of the supply capacity of one first generator can be expressed by P1 watt (W). The upper limit of the supply capacity of the first generator and the second generator can be expressed by P2 watts (W). Similarly, the upper limit of the supply capacity of the three generators from the first generator to the third generator can be expressed by P3 watts (W), and the supply capacity of the four generators from the first generator to the fourth generator can be expressed. The upper limit of is expressed by P4 watts (W). The supply capacity information is stored in the supply capacity storage unit 230 by the information processing unit 250, and the information processing unit 250 acquires and uses the supply capacity information from the supply capacity storage unit 230.

The communication unit 240 receives the power consumption information transmitted from the heat pump water heater 300, and outputs the received power consumption information to the information processing unit 250. Further, the communication unit 240 receives the demand forecast information and the supply capacity information transmitted from the administrator terminal 100, and outputs the received demand forecast information and the supply capacity information to the information processing unit 250. The communication unit 240 receives the operation plan information output from the information processing unit 250, and transmits the received operation plan information to the administrator terminal 100. The communication unit 240 receives the operation schedule information output from the information processing unit 250, and transmits the received operation schedule information to each heat pump water heater 300.

The information processing unit 250 receives the power consumption information, the demand forecast information, and the supply capacity information output from the communication unit 240, and executes various information processing. For example, each time the information processing unit 250 receives the power consumption information transmitted from the heat pump water heater 300, the information processing unit 250 stores the received power consumption information in the power consumption storage unit 210. For example, each time the information processing unit 250 receives the demand forecast information and the supply capacity information transmitted from the administrator terminal 100, the received demand forecast information is stored in the demand forecast storage unit 220, and the received supply capacity information is supplied. It is stored in the storage unit 230.

Further, when the information processing unit 250 acquires power consumption information from the power consumption storage unit 210, acquires demand forecast information from the demand forecast storage unit 220, and acquires supply capacity information from the supply capacity storage unit 230, the acquired power consumption Based on information, demand forecast information, and supply capacity information, operation plan information and operation schedule information are generated and output. Other information processing executed by the information processing unit 250 will be described later.

Next, the heat pump water heater 300 will be described. As shown in FIG. 3, the heat pump water heater 300 includes a communication unit 310 and a boiling control unit 320. The communication unit 310 can be realized by, for example, the above-mentioned network I / F200D. The boiling control unit 320 can be realized by, for example, the CPU 200A and the RAM 200B described above.

The communication unit 310 transmits the power consumption information to the server device 200. Further, the communication unit 310 receives the operation schedule information transmitted from the server device 200 and outputs the operation schedule information to the boiling control unit 320. The boiling control unit 320 controls the boiling of the heat pump water heater 300 based on the operation schedule information output from the communication unit 310. More specifically, the boiling control unit 320 starts boiling at the boiling start time and ends boiling at the boiling end time based on the operation schedule information.

Next, the operation of the server device 200 will be described with reference to FIGS. 7 to 10.

FIG. 7 is a flowchart showing an example of the operation of the server device 200. FIG. 8 is a diagram for explaining an example of a specific range for specifying the allowable power consumption. FIG. 9 is a diagram for explaining an example of allocation of power consumption information. FIG. 10 is a diagram for explaining a movement example of power consumption information.

First, as shown in FIG. 7, the information processing unit 250 acquires power consumption information (step S101). Next, the information processing unit 250 acquires the demand forecast information (step S102). Next, the information processing unit 250 acquires the supply capacity information (step S103). The processing order of steps S101, S102, and S103 is not particularly limited. For example, the information processing unit 250 may acquire the demand forecast information and the supply capacity information at different timings, and then acquire the power consumption information.

When the process of step S103 is completed, the information processing unit 250 then allocates the power consumption information (step S104). More specifically, first, the information processing unit 250 generates a specific range 10 that specifies an allowable power consumption amount, as shown in FIG. 8, based on the acquired demand forecast information and supply capacity information. In particular, the information processing unit 250 is set in the midnight charge time zone or the night charge time zone (hereinafter, simply referred to as the midnight charge time zone) from among the plurality of supply capacity upper limit values P1, P2, P3, and P4 included in the supply capacity information. The supply capacity upper limit value P2 that intersects the graph G representing the time-series power consumption is specified, and the range surrounded by the graph G and the supply capacity upper limit value P2 is determined as the specific range 10. That is, in the specific range 10, since the demand forecast is below the upper limit value P2 of the electric power that can be supplied by the first generator and the second generator, a margin or a surplus remains in the electric power supply capacity. Therefore, as shown in FIG. 9, the information processing unit 250 allocates a plurality of power consumption information to the specific range 10 in order. In the present embodiment, the information processing unit 250 allocates the power consumption information of the consumer A to the consumer D in order. In this way, by making the heat pump water heater 300 boil using the electric power supplied during the midnight charge time zone, the use of the heat pump water heater 300 during the daytime is reduced and the peak of the total power consumption is reduced. Can be made to.

Here, when allocating the power consumption information within the specific range 10, the information processing unit 250 allocates the power consumption information based on a predetermined allocation rule. First, as shown in FIG. 9, the information processing unit 250 allocates power consumption information based on the first allocation rule that completes the boiling of the heat pump water heater 300 near the time when the midnight charge time zone ends. As a result, it is possible to reduce the amount of heat (hereinafter referred to as heat dissipation loss) that is lost at the time from the completion of boiling of the heat pump water heater 300 to the start of use of the heat pump water heater 300.

That is, if the heating of the heat pump water heater 300 is completed at midnight (for example, 2:00 am or 3:00 am), the heat pump water heater 300 may not be used until the morning (for example, 7:00 am or 8:00 am). Is high. In this case, the heat pump water heater 300 dissipates heat from the boiling completion time of the heat pump water heater 300 to the start time of use, and the electric power consumed for boiling the heat pump water heater 300 may be wasted. However, by adopting the first allocation rule, heat dissipation loss can be reduced.

When the information processing unit 250 becomes unable to allocate the power consumption information based on the first allocation rule, the second operation unit 250 then starts boiling the heat pump water heater 300 near the time when the midnight charge time zone starts. Allocate power consumption information based on the allocation rule of. As a result, the power consumption information can be further allocated to the remaining area of the specific range 10 to which the power consumption information is not allocated. By adopting the second allocation rule, the use of the heat pump water heater 300 during the day can be further reduced to reduce the peak of total power consumption.

When the information processing unit 250 cannot allocate the power consumption information based on the second allocation rule, the third unit completes the boiling of the heat pump water heater 300 near the time when the midnight charge time zone ends. The power consumption information is allocated outside the specific range 10 based on the allocation rule of. For example, when the power consumption information of the consumer E (not shown) remains, the information processing unit 250 transfers the power consumption information of the consumer E to the power consumption information of the consumer A based on the third allocation rule. Stack up. As a result, the remaining power consumption information disappears.

When the processing of step S104 is completed, the information processing unit 250 then calculates the dispersion value before and after the movement of the power consumption information (step S105), and evaluates the dispersion value before and after the movement (step S106). Specifically, as shown in FIG. 10A, first, the information processing unit 250 is the sum of the power consumption information of the consumer A to the consumer D, which is the state immediately after being assigned to the specific range 10, and the specific range. The variance value before movement regarding the difference from 10 (more specifically, the error) is calculated. Next, as shown in FIG. 10B, the information processing unit 250 moves the power consumption information of the consumer A, who has the least heat dissipation loss, for one minute toward the start time of the midnight charge time zone. The variance value after the movement regarding the difference (more specifically, the error) between the total power consumption information of the consumer D and the specific range 10 is calculated. Then, the information processing unit 250 evaluates the dispersion value before the movement and the dispersion value after the movement.

When the process of step S106 is completed, the information processing unit 250 determines whether or not the dispersion value has decreased (step S107). More specifically, the information processing unit 250 determines whether or not the distributed value after the movement is reduced from the distributed value before the movement. When the information processing unit 250 determines that the dispersion value has decreased (step S107: YES), the information processing unit 250 moves the power consumption information (step S108). That is, since the variance value after the movement is reduced from the dispersion value before the movement, the difference between the total power consumption information after the movement and the specific range 10 is smaller than that before the movement, so that the information processing unit 250 is actually in demand. Move the power consumption information of house A toward the start time of the midnight charge time zone.

When the process of step S108 is completed, it is determined whether or not the predetermined number of movements has been reached (step S109). The number of settings is set for each movement direction and for each consumer's power consumption information. When the information processing unit 250 determines that the set number of times has not been reached (step S109: NO), the processing of steps S105 to S108 is repeated.

Therefore, if the dispersion value after the movement is smaller than the dispersion value before the movement, the information processing unit 250 consumes the consumer B, which has the second smallest heat dissipation loss after the consumer A, as shown in FIG. 10 (c). Move the power information toward the start time of the midnight charge time zone. On the contrary, if the dispersion value after the movement is not smaller than the dispersion value before the movement, as shown in FIG. 10D, the information processing unit 250 of the consumer C has the second smallest heat dissipation loss after the consumer B. Do not move power consumption information toward the start time of the midnight charge time zone. Then, the dispersion value before the movement according to the state shown in FIG. 10 (d) is compared with the dispersion value after the movement according to the state shown in FIG. 10 (e), and the dispersion value after the movement is before the movement. If it is less than the variance value, as shown in FIG. 10 (e), the power consumption information of the consumer D is moved toward the midnight charge time zone start time.

Further, when the information processing unit 250 completes the movement of all the power consumption information toward the midnight charge time zone start time, the power consumption information of each consumer is then charged in order from the power consumption information having the largest heat dissipation loss. Move toward the end time of the time zone until the set number of times is reached. For example, the power consumption information allocated based on the second allocation rule described above is allocated so as to start boiling the heat pump water heater 300 near the time when the midnight charge time zone starts, so that heat dissipation loss occurs. big. Therefore, the information processing unit 250 specifies the power consumption information as a movement target to be moved toward the end time of the midnight charge time zone, and calculates and evaluates the dispersion value before and after the movement. When the information processing unit 250 determines that the dispersion value has decreased, the information processing unit 250 moves the power consumption information to be moved by one minute toward the end time of the midnight charge time zone. The information processing unit 250 also executes such processing for the next movement target. As a result, the variance value converges, and the difference between the total power consumption information and the specific range 10 is reduced. As a result, the demand forecast portion in the midnight charge time zone is smoothed and approaches the supply capacity upper limit value P2. Therefore, it is possible to avoid consuming electric power during the time period including the peak during the day to boil the heat pump water heater 300, and it is not necessary to increase the number of operating generators.

The information processing unit 250 transmits operation plan information when the dispersion value has not decreased in the process of step S107 (step S107: NO) or when it is determined that the set number of times has been reached (step S109: YES). (Step S110). More specifically, the information processing unit 250 sends information including all power consumption information whose movement is completed and the boiling start time and boiling end time are fixed to the administrator terminal 100 as operation plan information of all heat pump water heaters 300. Send to. As a result, the employee who operates the administrator terminal 100 can confirm the operation plans of all the heat pump water heaters 300 targeted by the scheduling system S on the display device 120.

When the process of step S110 is completed, the information processing unit 250 then transmits the operation schedule information (step S111). More specifically, the information processing unit 250 divides the operation plan information for each customer to generate the operation schedule information, and transmits the operation schedule information of each customer to the heat pump water heater 300 of the customer. As a result, the boiling control unit 320 of the heat pump water heater 300 starts boiling at the boiling start time and ends boiling at the boiling end time based on the operation schedule information.

As described above, according to the first embodiment, the server device 200 includes a power consumption storage unit 210, a demand forecast storage unit 220, a supply capacity storage unit 230, and an information processing unit 250. The power consumption storage unit 210 stores power consumption information in which the magnitude and time of power consumption required for boiling the heat pump water heater 300 are associated with each customer. The demand forecast storage unit 220 stores demand forecast information representing a demand forecast of electric power consumed by equipment other than the heat pump water heater 300. The supply capacity storage unit 230 stores supply capacity information indicating the supply capacity of the generator that supplies electric power. Then, the information processing unit 250 allocates the power consumption information of each consumer within the specific range 10 that specifies the allowable power consumption amount based on the demand forecast information and the supply capacity information. After that, the information processing unit 250 calculates the dispersion value before and after the movement of the power consumption information regarding the difference between the total power consumption information and the specific range 10, and if the dispersion value after the movement is less than the dispersion value before the movement, the movement target. The power consumption information of is repeatedly moved in the direction of time. When the dispersion value after the movement becomes equal to or higher than the dispersion value before the movement, the information processing unit 250 transmits information including the power consumption information of each consumer as the operation plan information of the heat pump water heater 300. Thereby, the power consumption information of each consumer required for boiling the heat pump water heater 300 can be scheduled within the specific range 10 that the generator can tolerate.

As a result, the variation in heat dissipation loss among consumers A, B, C, and D is further reduced.

As described above, according to the second embodiment, it is possible to eliminate the variation in heat dissipation loss among consumers A, B, C, and D, and ensure fairness among consumers A, B, C, and D. be able to. In the second embodiment, the average time is used as an example of the average value, but the average calorific value may be used instead of the average time.
