The determination that there is power purchase is made based on whether or not it has been input in advance from the keyboard 243 that there is power purchase. Here, power purchase means that an electric power company purchases electric power.

If it is determined that there is power purchase, then it is determined whether there is a profit (S2410). The determination that there is a profit is made when it is previously input from the keyboard 243 that there is a profit. Here, "profitable" means a case where a profit is obtained when power is received from the electric power company at night and power is transmitted during the daytime. Whether or not a profit can be obtained is determined based on the power rate and the conversion efficiency.

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

When it is determined in S2400 whether or not there is power purchase, it is next determined whether or not the power generation amount is larger than the usage amount (S2430). If it is determined that the usage amount is equal to or greater than the power generation amount, then the shortage charge mode is executed (S2440).

On the other hand, if it is determined that the power generation amount is larger than the usage amount, then the storage heat storage mode is executed (S245).
0). FIG. 20 is a flowchart of full charge full power transmission mode control processing, and FIG. 21 is an explanatory diagram of electric power charges. Figure 2
The processing indicated by 0 indicates the processing content of S2420. First,
Fully charge the night battery (S2500). The night here is the time of the price A1 in FIG.

Charging is performed by operating the power sale charging unit 129, the input / output switching unit 135, and the switch unit 153. The voltage sensor 13 determines whether the battery is fully charged.
9 and the output value of the current sensor 141, a charging state calculation routine (not shown) is performed.

Further, full charge and nighttime heat storage are performed (S2510). The heat storage is performed by the air conditioner 111 and the water heater 113. Next, a power transmission schedule is created (S2520). In creating the power transmission schedule, first, the amount of power consumed in the time period when the power receiving price becomes expensive (here, the time period of price A2 in FIG. 21) is calculated based on S2340. Next, the electric power stored in the storage battery unit 131 is applied to the time zone when the power receiving price becomes 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 planned to be transmitted during the time period when the transmission price becomes expensive (here, the time period of price B3 in FIG. 21). In the schedule. Also, the solar cell unit 1
The electric power obtained from 07 incorporates a schedule for transmitting electric power, except for the amount consumed. In other words, the electric power obtained by the power generation transmits the rest of the electric power consumed for consumption.

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

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

When the accumulated heat is fully stored, the surplus of the generated power is transmitted (S2620). By the above daytime extra power transmission mode control, the surplus can be sold from the electric power obtained by the power generation.

FIG. 23 is a flow chart of power storage heat storage mode control. This process shows the contents of S2450.
First, all the output of the solar cell is charged (S27
00), power reception is stopped (S2710). That is, the power reception is stopped, the power generated by the solar cell unit 107 is consumed, and the surplus is stored.

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

With the above electricity storage heat storage mode, the electric power obtained from the solar energy by the solar cell unit 107 is preferentially consumed, and the increase in the received electric power amount 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 amount of power shortage on the next day is calculated (S2800). The amount of power shortage on the next day is calculated by subtracting the amount of power consumption on the next day calculated based on S2340 from the amount of power generation on the next day calculated based on S2230.

Next, the storage battery is charged at night with electric power corresponding to the power shortage (S2810). Next, the presence / absence of nighttime heat storage is determined (S2820). Whether or not to store heat at night is determined by an instruction previously input from the keyboard 243,
A judgment is made based on the amount of power shortage the next day. For example, if you plan to use air conditioning and heating or hot water supply the next day, and if the amount of power shortage is more than a predetermined amount, or if the amount of power generation is low early in the morning or if you plan to perform air conditioning and hot water supply in the morning, then night heat storage It is determined that it is necessary.

If it is determined that the nighttime heat storage is not performed, a discharge schedule for the case where the nighttime heat storage is not performed is created (S2830). First, the discharge schedule is created based on the power generation state of the next day, the stored power amount, and the consumption state. Here, a schedule that minimizes the amount of received power is created in the time zone of the price A2 in FIG. 21 in which the power receiving 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 the power obtained by power generation is preferentially consumed as the amount of power generation increases. Here, when the magnitude of the generated power exceeds the magnitude of the power consumption, the surplus portion is first turned to the stored power, and when the stored power amount is in the fully charged state, heat is stored next.

On the other hand, when it is judged that the heat is stored at night,
Heat storage by the air conditioner 111 and heat storage by the water heater 113 are performed during a time period when the electricity reception price at night becomes low (S28).
40), and then a discharge heat radiation schedule is created (S28).
50). The heat storage by the air conditioner 111 and the water heater 113 is
Perform 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 learned value of the heat consumption so far.

The discharge heat radiation schedule is created based on the prediction of the power generation amount, power consumption amount, and heat consumption amount of the next day. For example, during the time period of the price A1 where the power reception price is low, the received power is consumed. Price A, which is expensive for receiving electricity
During the time period of 2, the electricity storage, the heat storage, and the generated power are preferentially consumed.

After the discharge heat radiation schedule is created, heat is radiated according to the heat radiation schedule (S2860).
After S2830 or S2860, discharge is performed according to the discharge schedule (S2870). With the above shortage charge mode, it is possible to store only the amount of electric power and the amount of heat that will be lacking the next day at night and consume it the next day. Moreover, in terms of consumption, the generated power is preferentially consumed, then the stored power is consumed, and the power reception is minimized.

As described above, it is possible to make the most effective use of the electric power generated by the solar cell, and to obtain the maximum profit by using the hourly charge system and the power purchase system. Obtainable. FIG. 25 is a block diagram of the group distribution control device 301.

After the group distributed power supply command signal is generated,
An individual dispersion response signal is input (S3030). The individual distributed response signal is returned from the house energy control system 101 performing individual control. For example, a signal indicating whether a predetermined residential 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, the individual distributed power feed 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,
It includes a distributed power supply instruction value for commanding a charging rate, a private power transmission rate, and a reverse power transmission rate, which will be described later, to a predetermined house energy control system 101.

After the power supply command signal is generated, the group distributed power supply command signal is output (S3050) and the individual distributed power supply command signal is output (S3060). The group and individual distributed power supply command signals are output to the main terminal device 13. As a result, the distributed power supply command signal is sent to the optical cable 19 via the optical link device 15.
Moreover, the input is performed by the reverse route.

FIG. 27 is a flow chart 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
3100). The group distributed power supply command is input from the group terminal device 17 via the communication interface 21, as shown in FIG. Next, a group distributed power supply command signal is created (S3110). This is performed based on the input group distributed power supply command.

Next, the group distributed power supply command signal is transmitted (S3120). This transmission is performed by the transmitter 37. FIG. 28 is a flowchart of the group command reception control process. The group command reception control process is performed by the group distribution control device 3 shown in FIGS. 5 and 25.
01 is executed every predetermined time. First, the group distributed power supply command signal is received (S3200). This reception is performed by the receiver 303. Next, the group distributed power supply command is created (S3210).
The group distributed power supply command is issued based on the group distributed power supply command signal.

Next, the group distributed power supply command is output to the control device (S3220). As a result, the distributed power supply command output from the distributed power supply command station 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 processing is executed by the control device 115 that performs individual control at predetermined time intervals. First, an individual distributed power supply command signal is input (S
3230). As shown in FIG. 15, the input of the individual distributed power supply command signal is performed from the individual terminal device 18 via the communication interface 241. Next, the individual distributed power supply command is created (S3240). This is performed based on the input individual distributed power supply command signal.

Next, the 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.

First, the control state is input (S32).
60). As the control state, whether to perform distributed control or independent control, which will be described later, the amount of received power, the amount of power generation, the amount of reverse power transmission, and the like are fetched. Another determination of distributed control or independent control is made based on the state of the distributed control flag set by the distributed / independent control selection routine of FIG. 31 and the state of the independent control flag.

Next, the 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 station 7. After the signal is generated, the output is executed (S3280). As a result, the operating state of the home energy control system 101 is transmitted to the distributed power supply command station 7.

FIG. 31 is a flow chart of a distributed / independent control selection processing routine. This routine is executed by the CPU 233 of the control device 115 at predetermined time intervals. First, it is determined whether distributed or independent (S330).
0). This determination is based on whether the distributed control key 243A of the keyboard 243 shown in FIG.
Depending on whether B is pressed or not.

If it is determined that the data is distributed, the distribution control flag is set (S3310). The distribution control flag is set in a predetermined area of the RAM 237. After setting the dispersion control flag, this routine is once ended. On the other hand, if it is determined to be independent, the independent control flag is set (S3320). The independent control flag is the RAM 237.
Is set in a predetermined area.

FIG. 32 is a flowchart of the task selection processing routine. This process is activated by the CPU 233 at predetermined time intervals. First, it is determined whether the distributed control flag is set or the independent control flag is set (S3400). This decision is
This is performed by setting 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, the independent control task is executed (S3410).
If the distributed control flag is set, the distributed control task is executed (S3420). When the independent control task is selected, the control routine shown below is started.

The shortage charge mode routine is executed.

Thus, when the independent control is selected, the house energy control system 101 is operated independently without following the command from the distributed power supply command station 7. In this case, the transmission price B1 of the charge shown in FIG.
B2 and B3 and power receiving prices A1 and A2 are applied.
The measured value of the electric energy in this case is displayed on the display unit 1 shown in FIG.
It is displayed on 03GA to 103GD.

33, 35, and 36 are included in the distributed control task. When the distributed control task process is being executed, the distributed control power reception price C1 indicated by the dashed-dotted line in FIG. 21 and the distributed control power transmission price C2 indicated by the dashed two-dot line are applied. The measured value of the amount of electric power 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 processing is executed by the CPU 233. First, it is determined whether or not it is a program process (S3500). Judgment as to whether it is a program process or not is made based on the distributed power supply command. (Note that when group control is being performed, it is based on the group distributed power supply command, and when individual control is being performed, it is based on the individual distributed power supply command. Note.)
In other words, if the distributed power supply command includes a program processing command, it is determined that it is a program processing,
When the real-time control command is included, it is determined that it is not a program process.

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

If it is determined that the program is changed, then the distributed control program is changed (S3530). The distributed control program is the RAM 237.
Which is set in the distributed control table in the above, at a preset time, charging at a predetermined charging rate, private power transmission at a predetermined private power transmission rate, or reverse at a predetermined reverse power transmission rate. Power transmission is executed. Here, there are power supply command 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 command value is “−100” from 0:00 to 4:00, that is, the charging rate is 1
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, private power transmission rate 100%, distributed power supply from 10:00 to 12:00 The control of 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%, is performed from 12:00 to 15:00. Here, the charging rate indicates the ratio to the maximum possible charging capacity at that time, 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 power transmission rate indicates the ratio of the power transmission capacity from private power generation and private power storage to the power consumed by the private power supply. 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 a percentage. The reverse power transmission rate indicates an 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” is 0, and the distributed power supply instruction value “200” is the reverse power transmission rate of 100%.

After changing the distributed control program, or after not making any change, the distributed control program is executed next (S3540). The distributed control task processing routine can selectively execute execution of the distributed control program or real-time control based on the distributed power supply command transmitted from the distributed power supply command station 7.

FIG. 35 is a flowchart of the distributed control processing routine. This process is performed by the CPU 2 when the distributed control program is executed in S3540 of FIG.
It is executed by 33 every predetermined time. First, the distributed 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 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 content of the control program are determined. For example, the control parameter for charging the storage battery unit 131 is calculated at the charging rate of 50%.

After the control state is determined, the control is executed (S3630). This distributed control processing routine executes distributed power supply control according to the distributed control program instructed by the distributed power supply command station 7. FIG. 36 is a flowchart of the real-time control processing routine. This process is executed by the CPU 233 at predetermined time intervals when the real-time control is executed in S3510 of FIG.

First, it is determined whether or not the electricity is stored (S3).
700). When the distributed power supply instruction value included in the distributed power supply command transmitted from the distributed power supply command station 7 is between “−100” and less than “0”, it is determined that the power is stored. To do. If it is determined that the power is stored, then the charging rate is input (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 charging rate of 100% is input, and in the case of "-50", a charging rate of 50% is input.

Then, the charging rate is determined (S372).
0). The charging rate is determined based on the input charging rate by referring to the amount of electricity 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 consumed to the full power receiving capacity, 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). As a result, 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 reverse power transmission is performed (S3740). When the distributed power supply instruction value exceeds “100”, it is judged whether the reverse power transmission is “2”.
00 "or less. If it is determined that the reverse power transmission is not performed, then it is determined whether or not the private power transmission is performed (S3750). The determination of private power transmission is made when the distributed power supply instruction value is greater than “0” and less than or equal to “100”. If it is determined that the power transmission is not for private use, that is, if the distributed power supply instruction value is "0" here, the present routine is temporarily terminated.

On the other hand, if it is determined that the power transmission is for private use, then the private power transmission rate 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.

Then, the private power transmission rate is determined (S3).
770). The power transmission rate for private use is determined by the storage battery unit 13
It is determined in consideration of the remaining amount of 1. Normally, the entered value is decided as it is. Next, private power transmission is executed (S3780). For private power transmission, the power unit 109
Operate and execute. For private power transmission, the amount of power received from power sales should be minimized.

When it is determined in S3740 that the reverse power transmission is performed, the reverse power transmission rate is next 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 reverse power transmission rate is determined based on the amount of electricity 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 directly determined.

After the determination of the reverse power transmission rate, the reverse power transmission is executed at the determined reverse power transmission rate. Reverse power transmission is performed by the power unit 1
09 to operate. With this real-time control processing,
In response to the distributed power supply command from the distributed power supply command station 7 in real time, charging, private power transmission, or reverse power transmission is performed.

The power system control device 1 described above is
In response to a power supply command from the central power supply command station 3, a predetermined group of each house energy control system 101 is online-controlled in group units. In addition, the individual home energy control system is individually controlled online. In this embodiment, the house energy control system is used. However, the present invention is not limited to this, and the energy of a private electric work may be managed.
