[ Basic form]
FIG. 3 is a block diagram showing the configuration of the control system of the power supply control device 10 according to the basic form of the present invention.

  The power supply control device 10 includes a power storage system control unit 28 that controls the flow of each power described above.

  The power storage system control unit 28 includes a control condition setting unit 30, a charge / discharge amount schedule calculation unit 32, a charge / discharge control unit 34, and a power history storage unit 36.

  The control condition setting unit 30 includes operation keys for performing various settings and operations of the power supply control device 10, a monitor for performing various displays, and the like. The control condition setting unit 30 inputs and sets, for example, power rate data (such as a unit price of purchased power for each time zone and a unit price for selling solar power generation), operation condition data of the power storage device 18 and the like by operating an operation key or the like. In addition, for example, it is possible to display a power rate for the current time zone. The power charge data may be set by acquiring the latest power charge data from a power company via a network or the like.

  Further, the control condition setting unit 30 can set a saving mode to be described later. When the saving mode is set, the supply of electric power to the unattended living room 24 where no person exists is stopped.

  The charge / discharge amount schedule calculation unit 32 acquires the control condition data set by the control condition setting unit 30 and calculates the most economical charge / discharge amount schedule. For example, the charging / discharging schedule schedules the power storage device 18 to be charged using late-night power with a low power charge, and supplies the power of the power storage device 18 to the building 12 during the daytime when the power charge is high. Further, the charge / discharge amount schedule calculation unit 32 compares the average value of the power charge of the power stored in the power storage device 18 with the charge of the commercial power supply 14 in that time zone, and supplies the most economical power to the building 12. Schedule as follows. In addition, the generated power is supplied to the building 12 and the power storage device 18 based on the unit sales price and power unit price (purchased power unit price) of power using natural energy such as power generated by the solar power generation device 16. Or whether to sell to an electric power company, and performs scheduling according to the determination result. Note that when power is supplied to the building 12, power using natural energy is preferentially supplied. However, when the power sold using natural energy is higher than the power of the commercial power source 14, Then, the electric power using natural energy is sold, and the power of the commercial power supply 14 is scheduled to be supplied to the building 12.

  Charging / discharging control unit 34 controls charging / discharging of power storage device 18 according to the schedule calculated by charging / discharging amount schedule calculating unit 32. For example, when the power storage device 18 is charged using the power supplied from the commercial power supply 14 during the midnight power time period and the daytime time period is reached, the power stored in the power storage device 18 is used to store the building 12. Control is performed to supply power to each living room 24.

  The power history storage unit 36 is connected to the distribution board control unit 38, the solar power generation device 16, and the power storage device 18 that control input / output of power of the distribution board 26, and the power history storage unit 36. Thus, the input / output history of power to the distribution board 26, the solar power generation device 16, and the power storage device 18 is stored. As a result, when the charge / discharge amount schedule calculation unit 32 calculates the most economical charge / discharge amount schedule, the distribution board 26 moves to each room 24 based on the history stored in the power history storage unit 36. Predicting the amount of power to be supplied, the amount of power generated by the solar power generation device 16, the power generated by the solar power generation device 16 and the power stored in the power storage device 18 to the power company, etc. The most economical charging / discharging schedule can be created.

  Further, in the power supply control device 10, a human sensor 40 is provided in each living room 24 to detect the presence of a person in each living room 24, and the detection result of the human sensor 40 is sent to the distribution board control unit 38. It is designed to be entered.

  The distribution board control unit 38 controls the input / output of the power of the distribution board 26, and stops the power supply to the unattended room 24 when the saving mode is set by the control condition setting means. This makes it possible to supply power more economically.

Then, the process performed in the electrical storage system control part 28 of the electric power supply control apparatus 10 concerning the basic form of this invention comprised as mentioned above is demonstrated. FIG. 4 is a flowchart showing an example of the flow of processing performed by the power storage system control unit 28 of the power supply control device 10 according to the basic form of the present invention.

  First, in step 100, power charge data is acquired from the control condition setting unit 30 by the charge / discharge amount schedule calculation unit 32, and the process proceeds to step 102. That is, data on the power rate set in advance in the control condition setting unit 30 is acquired. For the power rate data, data such as the unit price of the power rate for each time zone and the unit price of generated power is preset in the control condition setting unit 30, and the charge / discharge amount schedule calculation unit 32 acquires the set data. To do.

  In step 102, the storage battery operating condition data is acquired from the control condition setting unit 30 by the charge / discharge amount schedule calculation unit 32, and the process proceeds to step 104. The storage battery operating condition data is set in advance in the control condition setting unit 30 such as the rated capacity, the upper limit of charging, the lower limit of discharging, the rated discharging power, the rated charging power, and the charging / discharging efficiency. Get the set data.

  In step 104, the charge / discharge amount schedule calculation unit 32 performs a generated power charge determination process, and the process proceeds to step 106. The generated power charge determination process is a process for determining whether or not the power generated by the solar power generation device 16 is stored in the power storage device 18, and is determined based on the acquired power rate data. Specifically, the power generated by the solar power generation device 16 is basically self-consumed preferentially, and the surplus is stored in the power storage device 18. At this time, when the unit price of generated power is equal to or less than the unit price of electricity price for each time period, the power is sold without storing electricity, and the unit price of generated power is less than the unit price of electricity price for each time period. In the case of the cheapest power charge, the power is stored in the power storage device 18 without selling power.

  In step 106, the charge schedule is calculated by the charge / discharge amount schedule calculation unit 32, and the process proceeds to step 108. The calculation of the charging schedule is performed, for example, so that charging is performed in a time zone in which the unit price of the power charge is the cheapest. Charging of the power storage device 18 starts charging the power storage device 18 with the rated charging power based on the set storage battery operating condition data, and ends when the charging upper limit is reached.

  In step 108, the discharge schedule is calculated by the charge / discharge amount schedule calculation unit 32, and the process proceeds to step 110. The calculation of the discharge schedule is performed, for example, so that the discharge is performed in a time zone in which the unit price of the power rate is most effective. The discharging of the power storage device 18 starts discharging at the rated discharge power based on the set storage battery operating condition data, and ends when the discharging lower limit is reached.

In step 110, a charge / discharge command is issued to the power storage device 18 according to the calculation schedule, and the process proceeds to step 112. As a result, the power storage device 18 is charged according to the charge schedule, and the power storage device 18 is discharged according to the discharge schedule. That is, it is possible to supply power to power the power rates charged to cheapest time zone expensive Toki簡band from the power storage device 18 to the building 12, it is possible to supply power to the building 12 economically it can. In addition, charging / discharging of the electrical storage apparatus 18 is performed based on the storage battery operating condition data set by the control condition setting unit 30.

  In step 112, commercial power trading power amount data, power generation amount data, and power storage amount data are stored in the power history storage unit 36, and the process proceeds to step 114. That is, when charging / discharging to the power storage device 18 is started according to the charge / discharge schedule, power flows between the commercial power source 14, the solar power generation device 16, the power storage device 18, and the distribution board 26. From the flow, commercial power trading power amount data, power generation amount data, and power storage amount data are stored in the power history storage unit 36. In addition, processing such as billing can be performed based on the data stored in the power history storage unit 36.

  In step 114, the charge / discharge amount schedule calculation unit 32 determines whether or not there is a change in the power charge. In this determination, for example, it is determined whether or not the power rate has been changed by the control condition setting unit 30. If the determination is affirmative, the process returns to step 100 and the above-described processing is repeated. That is, when there is a change in the power charge, the power charge data is acquired again and the processing from step 100 is started. If the determination is negative, the process proceeds to step 116. The determination as to whether or not there is a change in the power charge may be made by determining whether or not the power charge change data has been received from the power company by connecting to the power company via a network.

  In step 116, it is determined whether or not a predetermined time has come. For example, 23:00 is applied as a predetermined time, and it is determined whether or not 23:00 has been reached. If the determination is negative, the processing returns to step 110 and the above-described processing is repeated. If the determination is affirmative, the process returns to step 100 to acquire power data again and the above-described processing is repeated.

  Next, an example in the case where processing is performed as described above by the power storage system control unit 28 will be described. FIG. 5 shows an example of the current rate system, FIG. 6 shows an example of subdividing the late-night power rate with respect to the current rate system, and FIG. 7 shows a case where the purchase price of solar power generation falls drastically. An example of

  For example, as the power rate data, the power rate unit price data as shown in FIG. 5 (A) is set by the control condition setting unit 30, and the solar power generation unit price as shown in FIG. 5 (B) is set as the control condition. Setting is performed by the setting unit 30. The units in FIGS. 5A and 5B are shown as yen / kwh.

  Moreover, as storage battery control data, storage battery control data as shown in FIG. 5C is set.

  Further, the charge / discharge amount schedule calculation unit 32 determines whether or not to store solar power from the data in FIGS. 5 (A) and 5 (B). 5A and 5B, since the unit price of generated power is equal to or less than the unit price of the power rate for each time zone, the surplus of private consumption Sells power without charging the power storage device 18. That is, since it is more economical to sell than to store electricity, the power generated by the solar power generation device 16 is basically self-consumed preferentially, but the surplus is charged to the power storage device 18. Without selling to the power company.

  Then, the charge / discharge amount schedule calculation unit 32 calculates the charge schedule shown in FIG. In the case of FIG. 5D, charging of the power storage device 18 is started with the rated charging power during a time zone when the power is the cheapest, and charging is terminated when the charging upper limit is reached.

  Further, the charge / discharge amount schedule calculation unit 32 calculates the discharge schedule shown in FIG. In the case of FIG. 5 (E), the power storage device 18 starts discharging at the rated discharge power during a time period when the power is the most expensive, and the discharging ends when the charging lower limit is reached.

  Thus, an example of the charge / discharge performance in the case of performing control is shown in FIG. Note that the unit in FIG. 5F is indicated as kwh.

  Further, when the effect is obtained from FIG. 5F, it is as shown in FIG. That is, in this example, in this example, the total power charge is 78.8 yen.

  On the other hand, FIG. 6 shows a case where the charge for midnight power is subdivided. In this case, as the electric power data, the electric power unit price data as shown in FIG. 6 (A) is set by the control condition setting unit 30, and the solar power unit sales price as shown in FIG. 6 (B) is set. It is set by the control condition setting unit 30. The units in FIGS. 6A and 6B are shown as yen / kwh. Further, in FIG. 6A, late-night power is subdivided as compared to FIG. 5A, and the charge indicated by hatching in FIG. 6A is reduced.

  Moreover, as storage battery control data, storage battery control data as shown in FIG. 6C is set. In addition, FIG.6 (C) is the storage battery control data similar to FIG.5 (C).

  Further, the charge / discharge amount schedule calculation unit 32 determines whether or not to store solar power based on the data in FIGS. 6 (A) and 6 (B). 6A and 6B, since the unit price of generated power is equal to or less than the unit price of power charges for each time zone, the surplus of private consumption Sells power without charging the power storage device 18. That is, since it is more economical to sell than to store electricity, the power generated by the solar power generation device 16 is basically self-consumed preferentially, but the surplus is charged to the power storage device 18. Without selling to the power company.

  And the charging / discharging amount schedule calculation part 32 calculates the charging schedule shown in FIG.6 (D). In the case of FIG. 6D, charging of the power storage device 18 is started with the rated charging power in the time zone when the power is the cheapest, and charging is terminated when the charging upper limit is reached.

  Further, the charge / discharge amount schedule calculation unit 32 calculates the discharge schedule shown in FIG. In the case of FIG. 6 (E), discharging of the power storage device 18 is started with rated discharge power during a time period when the power is most expensive, and discharging is terminated when the charging lower limit is reached.

  Thus, an example of the charge / discharge performance in the case of performing control is shown in FIG. Note that the unit in FIG. 6F is indicated as kwh.

  Further, when the effect is obtained from FIG. 6F, it is as shown in FIG. That is, when the late-night power charge is subdivided, the total power charge is 98.3 yen in this example.

  FIG. 7 shows a case where the purchase price of photovoltaic power generation has dropped. In this case, as the electric power data, the data of the electric power unit price as shown in FIG. 7 (A) is set by the control condition setting unit 30, and the unit price of photovoltaic power generation as shown in FIG. 7 (B) is set. It is set by the control condition setting unit 30. The units in FIGS. 7A and 7B are shown as yen / kwh. Further, in FIG. 7B, the photovoltaic power generation drastically falls compared to FIG. 5B, and the portion indicated by hatching in FIG. 7B is cheaper.

  Moreover, as storage battery control data, storage battery control data as shown in FIG. 7C is set.

  Further, the charge / discharge amount schedule calculation unit 32 determines whether or not to store solar power from the data in FIGS. 7A and 7B. 7A and 7B, since the unit price of generated power <the unit price of the power rate for each time zone, the cheapest power rate is used. Charges the power storage device 18 without selling power to the power company. That is, it is more economical to store and use than to sell, so the power generated by the solar power generation device 16 is basically self-consumed preferentially, but the surplus is sent to the power company. The power storage device 18 is charged without being sold.

  And the charge / discharge amount schedule calculation part 32 calculates the charge schedule shown in FIG.7 (D). In the case of FIG. 7D, the electric power generated by the solar power generation device 16 having the lowest electric power is charged in the power storage device 18 and discharged after sunset for use. In addition, charging of the power storage device 18 is started with the rated charging power in the time zone of the unit price at which power is the second lowest, and charging ends when the charging upper limit is reached.

  Further, the charge / discharge amount schedule calculation unit 32 calculates the discharge schedule shown in FIG. In the case of FIG. 7 (E), discharge is started at the rated discharge power in the time zone of the unit price at which the power is the most expensive, and the discharge is terminated when the charge reaches the lower limit. In addition, after the sunset, the photovoltaic power generation starts discharging at the rated discharge power, and ends discharging when it reaches the charging lower limit.

  Thus, FIG. 7F shows an example of the results of charging and discharging when control is performed. Note that the unit in FIG. 7F is indicated as kwh.

  Further, when the effect is obtained from FIG. 7 (F), it is as shown in FIG. 7 (G). That is, in the case where the purchase price of solar power generation has dropped, the total power charge is 123.1 yen in this example.

Subsequently, processing performed in the control condition setting unit 30 will be described in detail.

  In step 202, the storage battery operating condition data is output according to the acquisition request of the charge / discharge amount schedule calculation unit 32, and the process proceeds to step 204. That is, when the storage battery operation condition data is acquired by the charge / discharge amount schedule calculation unit 32 in step 102 described above, the storage battery operation condition data preset by the control condition setting unit 30 is output.

  In step 204, the control condition setting unit 30 determines whether or not the saving mode is set. This determination is made by determining whether or not the saving mode is set by operating the control condition setting unit 30. If the determination is affirmative, the process proceeds to step 206. If the determination is negative, the process proceeds to step 208. To do.
