The water heater 13 adjusts the opening of the solenoid valves 95 and 96 and controls the water temperature in the hot water tank 91 based on the signal from the control device 15. FIG. 7 is a basic flowchart of water heater control. The water heater control is repeatedly executed by the CPU 111 shown in FIG.
In the water heater control, first, the water supply pipe control is started at predetermined time intervals (step 1000; hereinafter, the steps are simply described as S only). Next, the water pipe control is started every predetermined time (S1100). Next, the energization amount control is started every predetermined time (S1200). These are all time interrupted.

FIG. 8 shows a flowchart of the water supply pipe control processing. When the water supply pipe control is started, first, an input of the indicated water temperature is executed (S1300). The instructed water temperature is instructed from control device 15. Next, water temperature is input (S1).
310). The input of the water temperature is performed by the temperature sensor 97. Thereby, the temperature in the hot water tank 91 is input. Next, it is determined whether the water temperature has reached the instructed water temperature (S1320). If the indicated water temperature has already been reached, this routine is terminated once, and if the indicated water temperature has not yet been reached,
Next, input of the indicated water volume (S1330), input of the water volume (S1)
340). The input of the indicated water amount is performed by the control device 15 via the communication interface 117. The water amount is input from the water amount sensor 99.

Next, it is determined whether or not the water amount has reached the indicated water amount (S1350). If the water amount has reached the indicated water amount, the present routine is once terminated, and if not, the solenoid valve is opened for a predetermined time. Execute (S1360). Here, the solenoid valve 9
5 is controlled to be open for a predetermined time. As the predetermined time, FIG.
Set about several times the rounding time of the routine.

After the solenoid valve 95 is controlled to open, the processing is shifted to the beginning of this routine. By this water supply pipe control process, the warm water of the designated water temperature and the designated water amount is
Can be satisfied. FIG. 9 is a flowchart of a water supply pipe control processing routine.

First, input of the designated water supply amount (S1400),
Input of water amount (S1410), calculation of water supply amount (S142)
0) are sequentially executed. The instruction water supply amount is input from the control device 15. Here, a value obtained by subtracting a desired remaining water amount from the full water amount of the hot water tank 91 is set as the instructed water supply amount. The water amount is a value indicating the remaining water amount, and the value is input from the water amount sensor 99. The calculation of the water supply amount is performed based on the water amount. Here, the amount obtained by subtracting the remaining water amount from the full water amount of the hot water tank 91 is regarded as the water supply amount.

Next, it is determined whether or not the water supply amount has reached the specified water supply amount (S1430). If the water supply amount has reached the instructed water supply amount, this routine is ended once, and if not, the solenoid valve is opened for a predetermined time (S1440). That is, if water supply is possible, the solenoid valve 96 is controlled to be open for a predetermined time.

Thus, the amount of water supplied from the water heater 13 can be controlled by the control device 15. FIG. 10 is a flowchart of the energization amount control processing routine. First, the input of the command energization amount (S1500), the input of the command water temperature (S1510), and the input of the water temperature (S1520) are sequentially performed. The instructed energization amount is a value indicating a percentage of energization time of the power supplied to the heater 93, and is input from the control device 15.

The indicated water temperature is a value indicating the temperature of the hot water in the hot water tank 91 and is input from the control device 15. The water temperature is input from the temperature sensor 97. Next, it is determined whether the water temperature has reached the instructed water temperature (S1530). If the water temperature has reached the instructed water temperature, this routine is once ended as it is, and if not, a process of energizing for the prescribed amount of time with the instructed energization amount is executed (S1540). Here, a signal for instructing the current supply amount and the current supply time is output to the current control circuit 119.

After the energization is performed, the process returns to the beginning of this routine.
According to the current supply amount control processing routine, the retract switch unit 5
The current flowing from the heater 93 to the heater 93 can be controlled by the control device 15 to a desired state. FIG. 11 is a configuration diagram of the control device 15.

The control device 15 includes the input interface 13
1, the CPU 133, the ROM 135, and the RAM 137
, An output interface 139, a communication interface 141, a keyboard 143, and a display 145.
, An external storage device 147, and a solar radiation prediction device 151. The solar radiation prediction device 151 is connected to the input interface 131, determines the future weather condition from the regional characteristics of the measurement point and the pressure change state, estimates the amount of solar radiation the next day, and instructs the CPU 133 It is a device that outputs predictions.

Next, the processing executed by the control device 15 will be described. The power generation amount learning processing routine shown in FIG. 12 is executed by the CPU 133 at predetermined time intervals.
When the power generation amount learning processing routine is started, first, input processing of a generated current value is executed (S2000). The input processing of the generated current value is performed by inputting the output signal of the current sensor 43 via the communication interface 141.

Next, the amount of generated power is calculated (S2).
100). The calculation of the generated power amount is performed by multiplying a value obtained by integrating the input generated current value by a predetermined constant. Next, it is determined whether it is time to calculate the average power generation amount (S210).
5) If it is not the calculation time, this routine is once ended, and if it is the calculation time, the average power generation amount of the previous day is read (S2110). Whether or not the calculation time of the average power generation amount is determined based on whether or not a predetermined time at night has come. The average power generation amount of the previous day is input from the RAM 137.

After reading the average power generation amount of the previous day, the average power generation amount is calculated by correcting the average power generation amount of the current day (S2120). The amount of generated power today will be described later. This is a process of performing a weighted average of the average power generation amount up to the previous day and the power generation amount of today. After calculating the average power generation,
It is stored in M137 (S2130), and this routine is once ended.

The power generation amount prediction processing routine of FIG.
After the average power generation amount of S2130 of No. 2 is stored, it is started. First, the average power generation amount is read (S220).
0). The average power generation amount is stored in the RAM 13 by S2130.
The value stored in 7 is read and used. Then
The solar radiation prediction is read (S2210). The solar radiation prediction is input from the solar radiation prediction device 151.

Next, solar radiation correction of the average power generation is performed (S2220), and this solar radiation corrected power generation is stored in the RAM 137 (S2230). The solar radiation correction of the average power generation amount is for improving the estimation accuracy of the power generation amount of the next day. FIG.
9 is a flowchart of a consumption learning routine.

The consumption learning routine is executed by the CPU 133.
Is activated at predetermined time intervals. First, a current consumption value is input (S2300). The consumed current value is obtained by inputting an instruction value of the current sensor 21 through the input interface 131. 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 input from the RAM 137.

Next, the average power consumption per hour in the previous week is corrected with the power consumption today to calculate the average power consumption per hour today (S2330).
AM 137 is stored in the area of the day of the week (S234).
0). By this consumption learning routine, the average power consumption for each day of the week and for each hour is created in the RAM 137 as a table.

FIG. 15 is a flowchart of a control mode determination processing routine. The control mode determination process is performed by the CPU
By 133, it is started every predetermined time. First, it is determined whether there is a power purchase (S2400). The determination of the power purchase is made based on whether or not the power purchase has been input from the keyboard 143 in advance. 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 presence of a profit has been input from the keyboard 143 in advance. 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 that there is no power purchase in S2400, then it is determined whether the amount of power generation is greater than the amount of use (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, then the power storage and heat storage mode is executed (S245).
0). FIG. 16 is a flowchart of a full charge full power transmission mode control process, and FIG. 17 is an explanatory diagram of a power rate. FIG.
The processing shown in FIG. 6 shows 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. This price A1
Is the lowest receiving price.

Charging is performed by operating the power selling charging unit 29, the input / output switching unit 35, and the switch unit 53. The determination as to whether the battery is in the fully charged state is made based on the output values of the voltage sensor 39 and the current sensor 41 by a not-shown charge state calculation routine.

Further, the battery is fully charged and the heat is stored at night (S2510). As the heat storage, heat storage by the air conditioner 11 and heat storage by the water heater 13 are performed. Next, a power transmission schedule is created (S2520). In creating the power transmission schedule, first, the amount of power consumed in a time zone when the power reception price is expensive (here, the time zone of price A2 in FIG. 17) is calculated based on S2340. Next, the electric power stored in the storage battery unit 31 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 31 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. 17). Into the schedule. The power obtained from the solar cell unit 7 incorporates a power transmission schedule except for the amount of power consumed. 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 9. By the above full charge full power transmission mode control, power is received at night when the received power rate is the lowest,
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, it is possible to consume the power generated by the solar light and to sell the surplus power.

FIG. 18 is a flowchart of daytime extra power transmission mode control. FIG. 18 shows the processing content of S2425. First, excess generated power is stored and stored (S260).
0), and this is continued until the heat storage is full (S
2610). That is, while the power is consumed, the power generated in excess of the consumption is stored in the storage battery unit 31, and the air conditioner 11 and the water heater 13 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. 19 is a flowchart of the electric 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). In other words, power reception is stopped, the power generated by the solar cell unit 7 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 31 is completed and cannot be used for consumption, power is received and consumed.

In the above power storage / heat mode, power obtained from sunlight by the solar cell unit 7 is preferentially consumed, and an increase in received power can be avoided as much as possible. FIG. 20 is a flowchart of the shortage charging mode control. This processing 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 is determined based on an instruction input in advance from the keyboard 143 and the power shortage on the next day. For example, if you plan to use air conditioning / heating or hot water the next day,
In addition, when the power shortage is equal to or more than a predetermined amount, or when the amount of power generation is small in the early morning or when it is necessary to perform cooling / heating or hot water supply in the morning, it is determined that night-time heat storage is necessary.

Here, when it is determined that the night heat storage is not performed, a discharge schedule when the night 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. 17 in which the received power charge is high. For example, during the time of the price A2, while the amount of generated power is insufficient, the stored power is consumed, and the generated power is preferentially consumed as the amount of generated power increases. Here, when the magnitude of the generated power exceeds the magnitude of the power consumption, first, the surplus is transferred to the power storage, and when the amount of the power storage is fully charged, the heat is stored.

On the other hand, if it is determined that night-time heat storage will be performed,
The heat storage by the air conditioner 11 and the heat storage by the water heater 13 are performed during a time period when the nighttime power receiving price is low (S284).
0) Then, a discharge heat radiation schedule is created (S285).
0). The heat storage by the air conditioner 11 and the water heater 13 is executed 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).

In the shortage charging mode described above, the amount of power and the amount of heat which 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. In this embodiment described above, the power generated by the solar cell can be utilized most effectively and profit can be obtained. In addition, the maximum profit can be obtained by using the hourly fee system and the power purchase system. Can be obtained.

The present invention is not limited to the above embodiments, and various embodiments can be made without departing from the spirit of the present invention. For example, the power generation method is not limited to the method using a solar cell, and any means such as wind power generation may be adopted. Also, any heat storage method may be used.

[0098]

The energy control device of the present invention can control the storage and delivery of energy taken in from the outside according to the energy consumption state. Therefore, all of the consumed energy is covered by energy taken in from the outside, or the energy taken in from the outside is preferentially consumed as much as possible, and surplus energy is sent to the energy supply path to obtain profit. It becomes possible.

As a result, there is an extremely excellent effect that the energy taken from the outside or from the energy supply path generates the maximum profit.
