Invoked by First, a current consumption value is input (S2300). The consumed current value is obtained by inputting an instruction value of the current sensor 121 via the input interface 231. After the input of the current consumption value, the power consumption for each time is calculated (S2310). Next, the average power consumption is read for each hour on the same day of the previous week (S2320). The average power consumption for each hour of the previous week is R
Input from AM237.

Next, the average power consumption for each hour of the previous week is corrected with the power consumption for today to calculate the average power consumption for each hour for today (S2330).
AM 237 is stored in the area of the day of the week (S234).
0). With this consumption learning routine, the average power consumption for each day of the week and for each hour is created in the RAM 237 as a table.

FIG. 19 is a flowchart of a control mode determination processing routine. The control mode determination process is performed by the CPU
233. First, it is determined whether there is a power purchase (S2400). The determination as to whether or not there is power purchase is made based on whether or not it is input from the keyboard 243 in advance that there is power purchase. Here, power purchase means that a power company purchases power.

If it is determined that there is a power purchase, it is next determined whether or not there is a profit (S2410). The determination that there is a profit is made when the user has previously input that there is a profit from the keyboard 243. Here, the presence of a profit indicates a case where a profit is obtained when power is received from a power company at night and transmitted during the day. Whether or not a profit can be obtained is determined based on the power rate and the conversion efficiency.

If it is determined that there is a profit, a full charge full power transmission mode is executed (S2420). The content of the full charge full power transmission mode and details of other modes thereafter will be described later. On the other hand, if it is determined that there is no profit, the daytime extra power transmission mode is executed (S242).
5).

If it is determined in S2400 whether or not there is a power purchase, it is determined whether or not the power generation is larger than the used amount (S2430). Here, if it is determined that the usage amount is equal to or more than the power generation amount, the shortage charging mode is executed next (S2440).

On the other hand, if it is determined that the amount of power generation is larger than the amount of use, the power storage / storage mode is executed next (S245).
0). FIG. 20 is a flowchart of a full charge full power transmission mode control process, and FIG. 21 is an explanatory diagram of a power rate. FIG.
The processing indicated by 0 indicates the processing content of S2420. First,
The night storage battery is fully charged (S2500). The nighttime here is the time of price A1 in FIG.

Charging is performed by operating the power selling charging unit 129, the input / output switching unit 135, and the switch unit 153. The determination as to whether the battery is fully charged is made by the voltage sensor
9 based on the output value of the current sensor 141 and a charge state calculation routine (not shown).

Further, the battery is fully charged and the heat is stored at night (S2510). As the heat storage, heat storage by the air conditioner 111 and heat storage by the water heater 113 are performed. Next, a power transmission schedule is created (S2520). In the creation of the power transmission schedule, first, the amount of power consumed in the time zone when the power reception price is expensive (here, the time zone of price A2 in FIG. 21) is calculated based on S2340. Next, the power stored in the storage battery unit 131 is applied to a time period when the power receiving price is high. At this time, if the amount of power stored in the storage battery unit 131 is larger than the amount of power consumption, the surplus power is scheduled to be transmitted during a time period when the transmission price is expensive (here, a time period of the price B3 in FIG. 21). Into the schedule. Also, solar cell unit 1
Regarding the power obtained from 07, a power transmission schedule is incorporated except for the consumed amount. That is, the power obtained by the power generation transmits the remainder allocated to consumption.

Next, power transmission is performed according to the power transmission schedule (S2530). Power transmission is performed by the power unit 10
9. By the above full charge full power transmission mode control, power is received at night when the received power rate is low,
This power is consumed in a time period when the received power rate is expensive, and the power can be transmitted to obtain a margin. Moreover, while consuming the power generated by solar energy,
Surplus power can be sold.

FIG. 22 is a flowchart of daytime extra power transmission mode control, and shows the processing contents of S2425. First, the excess of the generated power is stored and stored (S2600), and this is continued until the stored and stored heat becomes full (S2610). That is, while the power is consumed and the power generated in excess of the consumption is stored in the storage battery unit 131, the air conditioner 1
11 and the water heater 113 are operated to store heat.

When the power storage is full, the surplus generated power is transmitted next (S2620). By the above-mentioned extra power transmission mode control in the daytime, surplus power can be sold from the power obtained by power generation.

FIG. 23 is a flowchart of the power storage / heat storage mode control. This processing shows the contents of S2450.
First, all the outputs of the solar cell are charged (S27).
00), power reception is stopped (S2710). That is, power reception is stopped, power generated by the solar cell unit 107 is consumed, and excess power is stored.

Next, it is determined whether or not the storage battery is fully charged (S2720). If the storage battery is fully charged, excess heat is stored (S2730). On the other hand, if it is determined that the storage battery is not in the fully charged state, it is next determined whether or not the storage battery is completely discharged (S2740). Here, if it is determined that the storage battery has not been completely discharged, the process proceeds to the beginning of this routine, and if the storage battery has been completely discharged, power reception is performed (S27).
50). In other words, when the discharge of the storage battery unit 131 is completed and the battery unit 131 cannot be used for consumption, power is received and consumed.

In the above-described power storage and heat storage mode, power obtained from solar energy by the solar cell unit 107 is preferentially consumed, and an increase in received power can be avoided as much as possible. FIG. 24 is a flowchart of the shortage charge mode control, and shows the contents of S2440. First, the power shortage on the next day is calculated (S2800). The next day's shortage electric energy is calculated by subtracting the next day's consumption calculated based on S2340 from the next day's generated power calculated based on S2230.

Next, the storage battery is charged with the power corresponding to the insufficient power amount at night (S2810). Next, the presence or absence of nighttime heat storage is determined (S2820). Whether or not to store heat at night depends on an instruction input in advance from the keyboard 243,
The determination is made based on the power shortage on the next day. For example, if there is a plan to use air conditioning and heating or hot water supply the next day, and the amount of power shortage is more than a predetermined amount, or if there is an early morning when power generation is small, or if there is a plan to perform air conditioning and hot water supply in the morning, A determination is made that it is necessary.

Here, when it is determined that night-time heat storage is not performed, a discharge schedule when night-time heat storage is not performed is created (S2830). The discharge schedule is created based on the power generation state, the amount of stored power, and the consumption state on the next day. Here, a schedule in which the amount of received power is minimized is created in the time zone of price A2 in FIG. 21 in which the received power charge is high. For example, during the time of price A2, while the amount of power generation is insufficient, the stored power is consumed, and as the amount of power generation increases, the power obtained by power generation is preferentially consumed. Here, when the magnitude of the generated power exceeds the magnitude of the power consumption, the surplus is first transferred to power storage, and when the amount of stored power is fully charged, heat is stored next.

On the other hand, when it is determined that night-time heat storage is performed,
The heat storage by the air conditioner 111 and the heat storage by the water heater 113 are performed during a time period when the nighttime power receiving price is low (S28).
40) Then, a discharge heat radiation schedule is created (S28).
50). The heat storage by the air conditioner 111 and the water heater 113
This is performed based on the estimated heat consumption of the next day. The estimated heat consumption of the next day is calculated by referring to the consumption schedule of the next day and the learning value of the heat consumption up to now.

The discharge heat radiation schedule is created based on the prediction of the power generation amount, the power consumption amount, and the heat consumption amount on the next day. For example, during the time zone of the price A1 where the power receiving price is low, the received power is consumed. Price A where the receiving price is expensive
In the second time zone, power storage, heat storage, and generated power are consumed preferentially.

After the discharge heat release schedule is created, heat is released according to the heat release schedule (S2860).
After S2830 or S2860, discharge is performed according to a discharge schedule (S2870). By the shortage charging mode described above, the amount of power and the amount of heat that are insufficient the next day can be stored at night and consumed on the next day. In addition, upon consumption, generated power is consumed preferentially, and then stored power is consumed to minimize power reception.

As described above, profits can be obtained by making the most effective use of the power generated by the solar cells, and maximum profits can be obtained by using the hourly fee system and the power purchase system. Obtainable. FIG. 25 is a block diagram of the group distribution control device 301.

For example, a signal indicating whether the predetermined house energy control system is in the distributed control state or the independent control state, or a signal indicating the execution state of the distributed control is returned.

Next, an individual distributed power supply signal is generated (S3040). The individual distributed power supply command signal is created based on the power supply command signal and the supply and demand forecast,

The output of the group and individual distributed power supply command signals is performed to the main terminal device 13. As a result, the distributed power supply command signal flows to the optical cable 19 via the optical link device 15.
Input is performed in the reverse route.

FIG. 27 is a flowchart of the group command transmission control process. The group command transmission control process is executed by the terminal transmission control device 11 at predetermined time intervals. First, a group distributed power supply command is input (S

This is performed based on the group distributed power supply command signal.

Next, a group distributed power supply command is output to the control device (S3220). Thereby, the distributed power supply command output from the distributed power supply command center 7 is input to the control device 115. FIG. 29 is a flowchart of the individual command input control process. The individual command input control process is executed at predetermined time intervals by the control device 115 that performs individual control. First, an individual distributed power supply command signal is input (S
3230). The input of the individual distributed power supply command signal is performed from the individual terminal device 18 via the communication interface 241 as shown in FIG. Next, an individual distributed power supply command is created (S3240). This is performed based on the input individual distributed power supply command signal.

Next, an individual distributed power supply command is output (S3250). This is performed for the distributed power supply command storage area in the RAM 237. FIG. 30 is a flowchart of the individual command output control process. The individual command output control process is executed by the control device 115 at predetermined time intervals.

As the control state, another type of distributed control, another type of independent control, a power reception amount, a power generation amount, a reverse power transmission amount, and the like are captured. Another determination of the distributed control or the independent control is made based on the state of the distributed control flag and the state of the independent control flag set by the distributed / independent control selection routine in FIG.

Next, an individual dispersion response signal is generated (S3270). The individual distributed response signal is for transmitting the input control state to the distributed power supply command center 7. After the generation of the signal, the output is executed (S3280). Thereby, the operation state of the home energy control system 101 is transmitted to the distributed power supply command center 7.

FIG. 31 is a flowchart of a distributed / independent control selection processing routine. This routine is executed by the CPU 233 of the control device 115 at predetermined intervals. First, it is determined whether the data is distributed or independent (S330).
0). This determination is made by checking whether the distributed control key 243A of the keyboard 243 shown in FIG.
This is performed depending on whether B has been pressed.

If it is determined that the distribution is performed, a distribution control flag is set (S3310). The distribution control flag is set in a predetermined area of the RAM 237. After setting the distribution control flag, the present routine is temporarily ended. On the other hand, if it is determined that they are independent, an independent control flag is set (S3320). The independent control flag is stored in the RAM 237

FIG. 32 is a flowchart of a task selection processing routine. This process is started by the CPU 233 every predetermined time. First, it is determined whether the distribution control flag is set or the independent control flag is set (S3400). This decision
This is performed according to the set state of the distributed control flag and the independent control flag in the RAM 237.

If it is determined that the flag is the independent control flag, an independent control task is executed (S3410).
If it is determined that the flag is the distributed control flag, the distributed control task is executed (S3420). When the independent control task is selected, the following control routine is started.

When the distributed control task process is being executed, a distributed control power receiving price C1 indicated by a one-dot broken line and a distributed control power transmission price C2 indicated by a two-dot broken line in FIG. 21 are applied. The measured value of the electric energy in this case is displayed on the display units 103GE and 103GF shown in FIG.

FIG. 33 is a flowchart of the distributed control task processing routine. This process is executed by the CPU 233. First, it is determined whether or not the processing is a program processing (S3500). The determination of the program processing is performed based on the distributed power supply command. (Note that when the group control is performed, it is based on the group distributed power supply command, and when the individual control is performed, it is based on the individual distributed power supply command. Write.)
In other words, if the distributed power supply command includes a program processing instruction, it is determined that the processing is a program processing,
If a real-time control instruction is included, it is determined that the processing is not program processing.

If it is determined that the processing is not the program processing, real-time control is executed next (S351).
0). This processing content will be described later. On the other hand, when it is determined that the processing is the program processing, it is determined whether the program is to be changed next (S3520). The determination as to whether the program is to be changed is made based on the distributed power supply command. That is, if the distributed power supply command includes a program change instruction, it is determined that the program is changed.

If it is determined that the program is to be changed, the distributed control program is changed next (S3530). The distributed control program is stored in the RAM 237
Are set in the distributed control table, and charge at a predetermined charging rate, private power transmission at a predetermined private power transmission rate, or reverse power at a predetermined reverse power transmission rate at a preset time. It performs power transmission. Here, there are power supply instruction programs S0 to U0 to O4 of the type shown in FIG. For example, in the power supply command program S0, the distributed power supply instruction value is “−100”, that is, the charging rate is 1 from 0:00 to 4:00.
00%, distributed power supply instruction value "0" from 4:00 to 8:00, that is, no control, distributed power supply instruction value "100" from 8:00 to 10:00, that is, 100% private power transmission rate, distributed power supply from 10:00 to 12:00. The instruction value "150", that is, the reverse power transmission rate of 50%, and the distributed power supply instruction value "200", that is, the reverse power transmission rate of 100%, are controlled from 12:00 to 15:00. Here, the charging rate indicates a ratio to the maximum possible charging capacity at that time, and the distributed power supply instruction value “0” indicates the charging rate 0, and the distributed power supply instruction value “100” indicates the charging rate 100%. The private transmission rate indicates the ratio of private power generation to private power consumption and the transmission capacity from private storage. The distributed power supply instruction value “0” indicates no private power transmission, and the distributed power supply instruction value “100” indicates the private power transmission rate 100. Indicates percentage. The reverse power transmission rate indicates the actual power transmission rate with respect to the maximum possible reverse power transmission capacity at that time, and the distributed power supply instruction value “100” indicates 0 and the distributed power supply instruction value “200” indicates the reverse power transmission rate of 100%.

After the change of the distributed control program or after the change is not performed, the distributed control program is executed next (S3540). According to the distributed control task processing routine, the execution of the distributed control program or the execution of the real-time control can be selectively performed based on the distributed power supply command transmitted from the distributed power supply command center 7.

FIG. 35 is a flowchart of the distributed control processing routine. This processing is executed when the distributed control program is executed in S3540 in FIG.
33 is executed every predetermined time. First, the distribution control table is input (S3600). The distributed control table is stored in a predetermined area in the RAM 237, and stores a distributed control program or the like that determines the timing of charging and reverse power transmission.

Next, the control state at the current time is calculated (S3610). As the control state at the current time, the power generation amount by the solar cell unit 107, the power storage amount of the storage battery unit 131, and the power consumption amount are calculated. Next, the control state is determined (S3620). The control state is determined according to the control state at the current time based on the distributed control program, and various control parameters for realizing the instruction control contents of the control program are determined. For example, a control parameter for charging the storage battery unit 131 at a charging rate of 50% is calculated.

After the control state is determined, the control is executed (S3630). With this distributed control processing routine, distributed power supply control is executed in accordance with the distributed control program instructed by the distributed power supply command center 7. FIG. 36 is a flowchart of the real-time control processing routine. This processing is executed by the CPU 233 every predetermined time when the real-time control is executed in S3510 of FIG.

First, it is determined whether or not the power storage is performed (S3).
700). When the distributed power supply command value included in the distributed power supply command transmitted from the distributed power supply command station 7 is between “−100” and “less than 0”, the storage is determined to be power storage. Do. Here, when it is determined that the power is stored, the charging rate is input next (S3710).
The charging rate is input based on the distributed power supply instruction value.
Here, when the distributed power supply instruction value is “−100”,
A charge rate of 100% is input, and in the case of "-50", a charge rate of 50% is input.

Next, the charging rate is determined (S372).
0). The determination of the charging rate is performed based on the input charging rate and referring to the amount of power stored in the storage battery unit 131 and other power consumption states. For example, when the charged amount is in a fully charged state or when the power is fully consumed, the charging rate is determined to be 0%. In other cases, the charging rate is determined without changing the input charging rate.

After the charging rate is determined, charging is performed (S3).
730). Thereby, charging is actually performed. on the other hand,
If it is determined in S3700 that the power is not stored, then it is determined whether or not the power is reverse power transmission (S3740). The determination as to whether the power transmission is reverse transmission is made by determining that the distributed power supply instruction value exceeds “100” and “2”.
00 ”or less. If it is determined that the power transmission is not reverse power transmission, it is next determined whether or not power transmission is for private use (S3750). The private power transmission is determined when the distributed power supply instruction value is greater than “0” and equal to or less than “100”. Here, if it is determined that the power transmission is not private power transmission, that is, if the distributed power supply instruction value is “0”, the present routine is temporarily terminated.

On the other hand, if it is determined that the power transmission is for private use, then the power transmission rate for private use is input (S3760).
The private power transmission rate is calculated based on the distributed power supply instruction value.
For example, if the distributed power supply instruction value is “50”, the private power transmission rate is 50%, and if the distributed power supply instruction value is “100” or more, the private power transmission rate is 100.

Next, the private power transmission rate is determined (S3).
770). The determination of the private power transmission rate is performed by the storage battery unit 13.
The determination is made in consideration of the remaining amount of No. 1. Normally, the input value is determined as it is. Next, power transmission for private use is performed (S3780). For private power transmission, the power unit 109
And execute. In private power transmission, the amount of power received from power sales is reduced as much as possible.

If it is determined in S3740 that the power transmission is a reverse power transmission, a reverse power transmission rate is input (S3790).
The reverse power transmission rate is calculated based on the distributed power supply instruction value. For example, when the distributed power supply instruction value is “150”, the reverse power transmission rate is 50%. Next, the reverse power transmission rate is determined (S3800). The determination of the reverse power transmission rate is performed based on the amount of power stored in the storage battery unit 131, the power generation state of the solar cell unit 107, and the like. Normally, the input reverse power transmission rate is determined as it is.

After the determination of the reverse power transmission rate, the reverse power transmission is performed at the determined reverse power transmission rate. Reverse power transmission, power unit 1
09 is operated. With this real-time control processing,
Charging, private power transmission, or reverse power transmission is performed in real time in response to a distributed power supply command from the distributed power supply command center 7.
