The display device 20 displays information related to the schedule provided from the control device 10 to the user. In addition, the display device 20 provides information input by the user to the control device 10. The display device 20 may be built in the control device 10.

  The measuring device 30 uses a current transformer (not shown) attached to the power line to generate power from the distributed power source 50, power consumption of the heat storage device 61 and the home appliance 62, and power supplied to the power storage device 63. Alternatively, the power supplied from the power storage device 63 is measured. Then, the measuring device 30 notifies the control device 10 of the measurement result.

  The power supply switching device 40 has a power switching element and is installed, for example, on a distribution board of the house H1. The power supply switching device 40 switches the power source that supplies power to the house H1 to the commercial power system PS1 or the commercial power system PS2 in accordance with a control command from the control device 10. The commercial power system PS1 is, for example, a commercial power source that supplies power stably but is provided by an electric power company with a relatively high electricity bill. Further, the commercial power system PS2 is a commercial power supply provided by an electric power company, for example, whose power supply is unstable, but whose electricity bill is relatively fixed.

The heat storage device 61 uses electric power collectively to boil hot water, for example, and does not return the thermal energy once stored to the electric power and output it. Note that the heat storage device 61 may obtain thermal energy using the power generated by the distributed power source 50 and the power stored in the power storage device 63 in addition to the power supplied from the commercial power systems PS1 and PS2.

  The home appliances 62a and 62b are electric devices that operate by consuming the power supplied from the commercial power systems PS1 and PS2, the power generated by the distributed power source 50, and the power stored in the power storage device 63. The home appliances 62a and 62b are, for example, air conditioners including a heat exchanger, a compressor, and an expansion valve, or a refrigerator, a television receiver, and a lighting device.

  FIG. 2 shows a hardware configuration of the control device 10. As illustrated in FIG. 2, the control device 10 is configured as a computer having a processor 101, a main storage unit 102, an auxiliary storage unit 103, an input unit 104, an output unit 105, and a communication unit 106. The main storage unit 102, the auxiliary storage unit 103, the input unit 104, the output unit 105, and the communication unit 106 are all connected to the processor 101 via the internal bus 107.

  The processor 101 includes, for example, a CPU (Central Processing Unit). The processor 101 executes a process described later by executing the program P1 stored in the auxiliary storage unit 103.

  The main storage unit 102 includes, for example, a RAM (Random Access Memory). The main storage unit 102 loads the program P1 from the auxiliary storage unit 103. The main storage unit 102 is used as a work area for the processor 101.

  The auxiliary storage unit 103 includes a nonvolatile memory such as a hard disk or a flash memory. The auxiliary storage unit 103 stores various data used for processing of the processor 101 in addition to the program P1. The auxiliary storage unit 103 supplies data used by the processor 101 to the processor 101 in accordance with an instruction from the processor 101, and stores the data supplied from the processor 101.

  The input unit 104 includes, for example, an input key and a capacitive pointing device. The input unit 104 acquires information input by the user of the control device 10 and notifies the processor 101 of the acquired information.

  The output unit 105 includes, for example, an LCD (Liquid Crystal Display) and a speaker. The output unit 105 presents various information to the user in accordance with instructions from the processor 101. The output unit 105 according to the present embodiment is formed integrally with a pointing device that configures the input unit 104, thereby configuring a touch screen.

  The control device 10 may be configured by omitting the input unit 104 and the output unit 105, and the display device 20 may be used as a user interface of the control device 10 instead of the input unit 104 and the output unit 105.

  The communication unit 106 includes a communication interface circuit for the control device 10 to communicate with other devices. The communication unit 106 receives a signal from the outside and outputs data included in the signal to the processor 101. In addition, the communication unit 106 transmits a signal including data output from the processor 101 to an external device.

  The control device 10 exhibits various functions by having the above hardware configuration. As shown in FIG. 3, the control device 10 acquires, as its function, an acquisition unit 11 that acquires various data and stores it in the storage unit 12, a schedule for controlling the data acquired by the acquisition unit 11 and the device, A storage unit 12 that stores information, a prediction unit 13 that predicts a transition of power used in the control system 1000, a schedule determination unit 14 that determines a schedule based on a prediction result of the prediction unit 13, a display device 20 or an output unit 105 It has a display control unit 15 for controlling and a device control unit 16 for controlling the device.

  The acquisition unit 11 is mainly realized by the processor 101 and the communication unit 106. The data acquired by the acquisition unit 11 includes constraint condition data D1 indicating a constraint condition for planning a schedule, measurement data D3 indicating a measurement result by the measurement device 30, and weather data distributed from a server device on the Internet NW. D4, user schedule D5 input by the user is included.

  The constraint condition is a condition that should be satisfied when the distributed power source 50, the heat storage device 61, the home appliance 62, and the power storage device 63 are operated. As described later, the constraint condition is for controlling the device so that this condition is satisfied. A schedule is planned. FIG. 4 shows an example of the constraint condition indicated by the constraint condition data D1 according to the present embodiment.

  As shown in FIG. 4, the constraint condition includes an operation mode desired by the user. This operation mode is one of a mode in which economy is emphasized, a mode in which energy saving is emphasized, and a mode in which user comfort is emphasized.

  When the user demands a mode that emphasizes economic efficiency, the contents of the constraint condition are that the electricity charge per month is less than the value set by the user, and the schedule can be changed so that the electricity charge is lowered. Changing the schedule so that the generated power can be used when there is a power generation suppression command, and changing the schedule if there is a power generation suppression command, and not purchasing new power by changing the schedule. Become.

  The power generation suppression command is a command from the electric power company and instructs to suppress the supply of the generated power by the power generator to the power system. The power generation suppression command is issued via the Internet NW by designating an upper limit value of the generated power in order for the power company to adjust the grid power.

  In addition, when the user demands a mode that emphasizes energy saving, the contents of the constraint conditions can be changed if the schedule can be changed so that the power supplied from the power company is reduced, and the power consumption is reduced. If the schedule can be changed, it will be changed.

  Further, when the user requests a mode that emphasizes comfort, the content of the constraint condition does not suppress the operation of the device.

  Further, the constraint condition includes peak cut power. The peak cut power means an upper limit value of power supplied to the control system 1000, and is equal to, for example, the breaker capacity of the house H1. The value of this peak cut power is a value set by a user or a value set by a demand response command (DR command).

  The acquisition unit 11 acquires the operation mode requested by the user via the display device 20 or the input unit 104 as a constraint condition. Furthermore, when the user demands a mode that emphasizes economic efficiency, the acquisition unit 11 sets the target value of the monthly electricity bill input by the user via the display device 20 or the input unit 104 as a constraint condition. Get as. In addition, when the user demands a mode in which economy is emphasized, the acquisition unit 11 acquires the power generation suppression command as a constraint condition.

  Returning to FIG. 3, the storage unit 12 is mainly realized by the auxiliary storage unit 103. In addition to the data stored by the acquisition unit 11, the storage unit 12 stores data used by the prediction unit 13, the schedule determination unit 14, the display control unit 15, and the device control unit 16. The data stored in the storage unit 12 includes device power data D2 indicating power consumption of a device to be controlled, a reference schedule D10 serving as a reference for controlling the device, a first operation schedule D11 of the heat storage device 61, home appliances The second operation schedule D12 of the device 62 and the third operation schedule D13 of the power storage device 63 are included.

  The first operation schedule D11, the second operation schedule D12, and the third operation schedule D13 are created by the schedule determination unit 14 by changing the reference schedule D10. Hereinafter, the first operation schedule D11, the second operation schedule D12, and the third operation schedule D13 are collectively referred to as an operation schedule.

  The device power data D2 is data indicating the power consumed by each home appliance 62 in association with the operation state of each home appliance 62. FIG. 5 schematically shows an example of the device power data D2. The device ID in FIG. 5 is an identifier for identifying each home appliance 62. In the example shown in FIG. 5, the same ID as that of each of the home appliances 62a and 62b is used as the device ID. Further, the power consumption “900-1000 W” associated with the operation state “water heater” in FIG. 5 means that the power consumption fluctuates in the range from 900 W to 1000 W.

  The measurement data D3 is data in which measurement results of the measurement device 30 are accumulated, and is generated power by the distributed power source 50, power consumption of the heat storage device 61 and the home appliance 62, and power supplied to the power storage device 63 or power storage. A history of power supplied from the device 63 is shown. The meteorological data D4 is data obtained by accumulating forecast values and observed values of information related to weather.

  The reference schedule D10 is a standard schedule for controlling the heat storage device 61, the home appliance 62, and the power storage device 63. For example, since the electricity bill is often low at night, the power consumption of the heat storage device 61 and the charging of the power storage device 63 are planned at night in the reference schedule D10. For example, as illustrated in FIG. 6, the reference schedule D <b> 10 associates the operation state of the heat storage device 61, the home appliance 62, and the power storage device 63 with the start time and the end time of operation in this operation state. Data. The reference schedule D10 may be created in advance by the processor 101 or may be input in advance by the user.

  The first operation schedule D11, the second operation schedule D12, and the third operation schedule D13 are created in this order by the schedule determination unit 14 and stored in the storage unit 12. The first operation schedule D11 is determined according to the constraint condition for the heat storage device 61, the second operation schedule D12 is determined according to the constraint condition for the home appliance 62, and the third operation schedule D13 is determined according to the constraint condition for the power storage device 63. .

  The prediction unit 13 is mainly realized by the processor 101. The prediction unit 13 predicts the transition of power used in the control system 1000 based on the data stored in the storage unit 12. For example, the prediction unit 13 predicts the power used by the heat storage device 61, the home appliance 62, and the power storage device 63 that operate according to the reference schedule D10 by combining the reference schedule D10 and the device power data D2. Similarly, the prediction unit 13 predicts the electric power used by the heat storage device 61, the home appliance 62, and the power storage device 63 that operate according to these operation schedules by combining the operation schedule and the device power data D2. In addition, the prediction unit 13 predicts the transition of power generated by the distributed power source 50 by combining the measurement data D3 and the weather data D4. Note that the prediction unit 13 may predict the transition of power based on the data directly acquired from the acquisition unit 11 without reading the data stored in the storage unit 12.

  The schedule determination unit 14 is mainly realized by the processor 101. The schedule determination unit 14 changes the time at which the heat storage device 61, the home appliance 62, and the power storage device 63 that are planned in the reference schedule D10 are operated, thereby satisfying the first operation schedule D11 and the second operation schedule D12 that satisfy the constraint conditions. And the 3rd driving schedule D13 is planned.

  The display control unit 15 is mainly realized by the processor 101. The display control unit 15 causes the display device 20 or the output unit 105 to display information related to the reference schedule D10 and the operation schedule. The information displayed by the display control unit 15 may include, for example, the schedule itself, or may include an effect when the device is operated according to the operation schedule by comparing the reference schedule D10 with the operation schedule. Good. This effect includes, for example, loss of electricity charges and increase / decrease in power consumption of the control system 1000. Then, the display control unit 15 inquires of the user which of the reference schedule D10 and the operation schedule is adopted.

  The device control unit 16 is mainly realized by the processor 101 and the communication unit 106. The device control unit 16 controls the heat storage device 61, the home appliance 62, and the power storage device 63 according to the schedule selected by the user among the reference schedule D10 and the operation schedule.

  Then, the schedule plan process performed by the control apparatus 10 is demonstrated using FIGS. The schedule planning process shown in FIG. 7 starts at a specific timing. This timing is when, for example, when the regular time, weather data D4 or user schedule D5 is changed, the predicted value by the prediction unit 13 and the measured value by the measurement device 30 are significantly different.

  As shown in FIG. 7, first, the acquisition unit 11 acquires a constraint condition (step S1). Specifically, the acquisition unit 11 inquires about the operation mode requested by the user via the output unit 105 or the display device 20. For example, when a mode in which economy is emphasized is designated by the user, the acquisition unit 11 substantially acquires the constraint condition (see FIG. 4) indicated by this mode. Moreover, the acquisition part 11 inquires a user about peak cut electric power, and acquires the value input by the user as a constraint condition. Moreover, when the power generation suppression command is issued, the acquisition unit 11 acquires the command including the target value of the power generation amount as a constraint condition.

  Next, the acquisition unit 11 acquires data including measurement data D3, weather data D4, and user schedule D5 (step S2).

  Next, the prediction unit 13 predicts the transition of the power consumption of these devices when the heat storage device 61, the home appliance 62, and the power storage device 63 are operated according to the reference schedule D10 (step S3).

  Next, the schedule determination part 14 plans the 1st driving | operation schedule D11 of the thermal storage apparatus 61 which satisfy | fills constraint conditions based on the prediction result of step S3 (step S4). For example, after a mode for emphasizing economy is designated and a power generation suppression command is issued, in step S3, the generated power that is instructed to be reduced and the power necessary for the water heater operation of the heat storage device 61 are supplied. When it is predicted that it can be covered, the schedule determination unit 14 creates the first operation schedule D11 by shifting the water heater operation of the heat storage device 61 from night to daytime. That is, the generated power used by the control system 1000 at the time specified by the power generation suppression command is larger than the power generated when the power generation suppression command is not issued. As a result, the generated power can be used effectively while suppressing the reverse flow of the generated power to the power system.

  However, as shown in FIG. 8, when new power purchase from the commercial power systems PS1 and PS2 occurs by shifting the boiling operation of the heat storage device 61, the schedule determination unit 14 stores the heat in this way. The water heater operation of the device 61 is not shifted. Thereby, the creation of an operation schedule that violates the constraints is avoided. Note that boxes L11 and L12 in FIG. 8 indicate the power consumption of the heat storage device 61, the box L13 indicates the power consumption of the home appliance 62, and the line L20 indicates the generated power. The shaded area in FIG. 8 indicates the amount of power that needs to be newly purchased from the commercial power systems PS1 and PS2 due to a shift in the water heater operation.

  In addition, when the electric power used by the control system 1000 exceeds the peak cut power Th by shifting the boiling operation of the heat storage device 61 as shown in FIG. 9, the schedule determination unit 14 thus makes the heat storage device 61 Do not shift the water heater operation. Thereby, the creation of an operation schedule that violates the constraints is avoided.

  Returning to FIG. 7, the prediction unit 13 predicts the power consumption of the heat storage device 11 (step S <b> 5). Specifically, the prediction unit 13 predicts the transition of the power consumption of the heat storage device 61 when the heat storage device 61 operates according to the first operation schedule D11 planned in step S4.

  Next, the schedule determination part 14 plans the 2nd driving schedule D12 of the household appliances 62 which satisfy | fill a constraint condition based on the prediction result of step S5 (step S6). Since the electric power consumption of the home appliance 62 changes according to the usage status by the user, it is preferable that the schedule determination unit 14 creates the second operation schedule D12 with reference to the user schedule D5.

  Next, the prediction unit 13 predicts power usage of the home appliance 62 (step S7). Specifically, the prediction unit 13 predicts the transition of the power consumption of the home appliance 62 when the home appliance 62 is operated according to the second operation schedule D12 planned in step S6.

  Next, the schedule determination part 14 plans the 3rd driving | running schedule D13 of the electrical storage apparatus 63 which satisfy | fills constraint conditions based on the prediction result of step S7 (step S8). The third operation schedule D13 is a charge / discharge plan for the power storage device 63, and is created so that, for example, the charge amount of the power storage device 63 is maintained at a constant value as long as the constraint condition is satisfied. This constant value corresponds to, for example, a charging rate of 50% with little deterioration of the storage battery.

  Next, the prediction unit 13 predicts the power usage of the power storage device 63 (step S9). Specifically, the prediction unit 13 predicts the transition of the power used by the power storage device 63 when the power storage device 63 is operated according to the third operation schedule D13 planned in step S8.

  Next, the display control unit 15 causes the display device 20 or the output unit 105 to display information related to the reference schedule D10 and the operation schedule, and inquires of the user whether to use the reference schedule D10 or the operation schedule (step) S10).

  FIGS. 10 and 11 each show an example of the screen displayed in step S10. In these examples, as information on the reference schedule D10 and the operation schedule, the transition of the generated power and the power consumption when the device operates according to the respective schedules, the profit and loss of the electricity charge when the operation schedule is adopted, and the power consumption The amount of increase or decrease is shown.

  When the user selects the “Yes” or “No” button on the screens shown in FIGS. 10 and 11, the reference schedule D10 or the operation schedule is adopted. And the apparatus control part 16 will control an apparatus according to the employ | adopted schedule.

  As described above, the control device 10 according to the present embodiment acquires the constraint condition that the heat storage device 61, the household electrical appliance 62, and the power storage device 63 should satisfy, and the first operation according to the constraint condition for the heat storage device 61. The schedule D11 was planned, the 2nd driving schedule D12 according to the constraint condition was planned about the household appliances 62 after that, and the 3rd driving schedule D13 according to the constraint condition was further planned about the electrical storage apparatus 63 after that. Thereby, compared with the case where the schedule for controlling the thermal storage apparatus 61, the household appliance 62, and the electrical storage apparatus 63 is planned simultaneously, the calculation load concerning a schedule plan can be reduced.

  In general, the heat storage device 61 is efficient when boiling water using electric power all at once, and is inefficient when boiling water using intermittent electric power or small electric power. For this reason, it is preferable to use electric power collectively. Here, if the first operation schedule D11 of the power storage device 61 is determined after the operation schedule of the other devices including the home appliance 62 and the power storage device 63 is determined, scheduling with high power use efficiency is consequently difficult. become. In the present embodiment, the first operation schedule D11 of the power storage device 61 is determined before the operation schedule of other devices, thereby increasing the power utilization efficiency.

  Further, since the power storage device 63 can output the stored power, there is a large room for changing the charge / discharge schedule as long as the charge amount is secured to some extent. In other words, changing the charge / discharge schedule has little effect on the user. For this reason, the freedom degree for changing the 2nd driving schedule D12 is ensured by defining the 3rd driving schedule D13 of the electrical storage apparatus 63 after the 2nd driving schedule D12 of the household appliance 62. As a result, the second operation schedule D12 that improves the convenience for the user can be determined.

  Further, the control device 10 causes the display device 20 or the output unit 105 to display information related to the planned schedule. Thereby, the user is notified of information related to the schedule before operating the device according to the schedule. Therefore, it is possible to prevent the device from being controlled by the user. As a result, the convenience of the user can be improved.

  As mentioned above, although embodiment of this invention was described, this invention is not limited by the said embodiment.

  For example, the screen displayed by the display control unit 15 may include past performance evaluations in addition to the planned schedule selection screen. 12 and 13 show the actual loss or gain of the electricity bill and the actual increase / decrease amount of the power consumption as the evaluation of the past results. Thereby, the user can recognize an error between the prediction of the power consumption based on the planned schedule and the power consumption due to the actually operated device.

  In the above embodiment, the operation schedule is planned according to the operation mode requested by the user. However, the operation schedule according to each operation mode is created, and the display control unit 15 compares the operation modes. You may display the screen which can do.

  Moreover, in the said embodiment, although the user selected any one of the reference | standard schedule D10 and a driving schedule, a user may correct the selected schedule.

  The power system specified by the control device 10 for the power supply switching device 40 may be input to the control device 10 by the user. Thereby, the user can select a preferable power source according to the stability of the power supply or the electricity bill.

  In the said embodiment, although an example (FIG. 4) of a constraint condition was shown, a constraint condition is not restricted to this. For example, in the case where power is supplied from the commercial power system PS1 with low power supply stability, it may be set as a constraint that the heat storage device 61 is not operated.

  Moreover, in the said embodiment, although it was assumed planning the driving | operation schedule which satisfy | fills all the constraints, it is not restricted to this. For example, you may plan the driving schedule which satisfy | fills a fixed ratio among many restrictions.

  Moreover, in the said embodiment, although the heat storage apparatus 61 and the electrical storage apparatus 63 which comprise the control system 1000 were respectively one, two or more may be sufficient. In this case, the first operation schedule D11 for two or more heat storage devices 61, the second operation schedule D12 for two home appliances 62a and 62b, and the third operation for two or more power storage devices 63. Schedule D13 is planned in this order.

  In addition, the energy storage device group 60 may include devices other than the heat storage device 61 that stores thermal energy and the power storage device 63 that has a storage battery. For example, equipment that stores kinetic energy by rotating flywheels using electrical power may be included. However, when it is possible to supply electric power from the energy stored in the device into the house H1, it is desirable to determine the schedule of the device in the same manner as the power storage device 63. In other cases, the schedule of the device is preferable. Is preferably determined in the same manner as the heat storage device 61.

  The functions of the control device 10 according to the above-described embodiment can be realized by dedicated hardware or by a normal computer system.

  For example, the program P1 stored in the auxiliary storage unit 103 can be read by a computer such as a flexible disk, a CD-ROM (Compact Disk Read-Only Memory), a DVD (Digital Versatile Disk), and an MO (Magneto-Optical disk). By storing and distributing in a recording medium and installing the program P1 in a computer, an apparatus for executing the above-described processing can be configured.

  Further, the program P1 may be stored in a disk device included in a server device on a communication network represented by the Internet, and may be downloaded onto a computer, for example, superimposed on a carrier wave.

  The above-described processing can also be achieved by starting and executing the program P1 while transferring it via a network represented by the Internet.

  Furthermore, the above-described processing can also be achieved by executing all or part of the program P1 on the server device and executing the program P1 while the computer transmits / receives information related to the processing via the communication network. .

  Note that when the above functions are realized by sharing an OS (Operating System) or when the functions are realized by cooperation between the OS and an application, only the part other than the OS may be stored in a medium and distributed. It may also be downloaded to a computer.

  The means for realizing the function of the control device 10 is not limited to software, and part or all of the means may be realized by dedicated hardware (for example, a circuit). For example, if the acquisition unit 11, the prediction unit 13, the schedule determination unit 14, the display control unit 15, and the device control unit 16 are configured using an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit), the control is performed. Power saving of the device 10 can be achieved.
