First Embodiment
FIG. 1 is a diagram showing an outline of a power control system 10 according to the present embodiment. The power control system 10 according to the present embodiment includes a storage battery 120, a power measurement unit 140, a calculation unit 150, and a battery control unit 160. Storage battery 120 is connected to a power line 130 connected to power network 20 through power reception facility 110. The power measuring means 140 measures the power supplied from the power grid 20 to the power line 130. The calculating means 150 predicts the predicted value of the average power in the target time zone from the predetermined time to a predetermined time after the predetermined time or the prediction of the power consumption of the target time zone based on the measurement result of the power measuring means 140 A value is calculated for each reference time in the target time zone. Battery control means 160 controls release charging of storage battery 120 based on the predicted value and a predetermined reference value. Details will be described below.

Power control system 10 according to the present embodiment is configured using, for example, control device 30. Control device 30 is a control device that controls storage battery 120. Control device 30 includes calculation means 150 and battery control means 160.

FIG. 2 is a diagram illustrating the hardware configuration of the power control system 10 according to the present embodiment. In the example of this figure, the power control system 10 has the load 301, the storage battery 120, and the control apparatus 30.

The power network 20 is, for example, a system such as a commercial power source, a power system, or a transmission and distribution network, which integrates equipment for supplying power from a power generation facility possessed by a power producer to a power reception facility possessed by a customer. is there.

The load 301 and the storage battery 120 are connected to the power network 20 via the distribution board 303. The load 301 and the storage battery 120 are not limited to one each. Further, a plurality of storage batteries 120 may be connected to one distribution board 303. The load 301 consumes the power supplied from the power grid 20. For example, the load 301 is an electrical device or the like, but is not limited to this. Further, a distribution board 303 may be further provided downstream of the distribution board 303 (opposite to the power grid 20).

The storage battery 120 charges the power supplied from the power network 20 under the control of the battery control means 160 of the control device 30, and stores the charged power. In addition, the storage battery 120 discharges the stored power under the control of the battery control means 160 of the control device 30. Details will be described later.

Further, between the distribution board 303 and the power network 20, a measuring instrument 308 and a power conversion facility 302 are provided. The power conversion facility 302 is a facility that converts the form of power sent from the electric power company into the form of power suitable for the load 301. The power conversion facility 302 converts, for example, the high voltage of the power sent from the power company into a voltage suitable for the load 301. In the example of this figure, the power receiving facility 110 is composed of a power conversion facility 302.

A storage battery 120 and a load 301 are connected downstream of the measuring instrument 308 (opposite to the power grid 20). The measuring instrument 308 is used to measure the current [A] (instantaneous value) in the power consumed by the load 301 and the storage battery 120 and the voltage [V] (instantaneous value) in the power consumed by the load 301 and the storage battery 120 Be The measuring instrument 308 is used to obtain the power value [W] (instantaneous value) and the amount of power [Wh] of the power (power consumption) consumed by the load 301 and the storage battery 120, and as the power measuring means 140 Function. Note that the consumption of power by storage battery 120 may include charge and discharge performed by storage battery 120. Therefore, the measuring instrument 308 is used to measure the sum of the value related to the power consumed by the load 301 and the value related to the power when the storage battery 120 is charged and discharged. That is, this total value corresponds to the value related to the power supplied from power network 20 to power line 130 in power control system 10. In addition, when charged by the storage battery 120, the charged power is "positive power consumption", and when discharged by the storage battery 120, the discharged power is "negative power consumption". In addition, it is not limited to the example of this figure, The measuring device 308 may be provided integrally with the power conversion installation 302, and may be provided between the electric power network 20 and the power conversion installation 302. FIG.

Control device 30 manages storage battery 120. The control device 30 includes a bus 311, a processor 312, a memory 313, a storage 314, and an input / output interface 315. With such a configuration, control device 30 has a function as a computer that executes a program.

The bus 311 has a function of a processor 312, a memory 313, a storage 314, and an input / output interface 315 as data transmission paths for transmitting and receiving data to and from each other. The processor 312 is an arithmetic processing unit such as a central processing unit (CPU) or a graphics processing unit (GPU). The memory 313 is a storage device such as a random access memory (RAM) or a read only memory (ROM). The storage 314 is a storage device such as a hard disk, a solid state drive (SSD), or a memory card. The storage 314 may also be a memory such as a RAM or a ROM.

The storage 314 stores programs such as a battery control module and a calculation module. The processor 312 implements the battery control means 160 and the calculation means 150 by respectively executing these modules stored in the storage 314. The storage 314 also functions as a storage unit 180.

The input / output interface 315 is an interface (I / F) for the control device 30 to transmit / receive data to / from an external device. Specifically, input / output interface 315 is used for control device 30 to control storage battery 120. The input / output interface 315 is also used to obtain the current value and the voltage value of the power consumption from the measuring instrument 308. In addition, the input / output interface 315 may be an interface for transmitting and receiving information via the communication network 400. Furthermore, the input / output interface 315 may be an interface for acquiring information from an input device such as a keyboard, or may be an interface for acquiring information from an external device such as a storage.

The power conversion facility 302, the measuring instrument 308, the distribution board 303, the storage battery 120, and the load 301 are facilities of the power consumer. One of the contract forms when a power demander purchases power from a power seller is a system called demand charge system as follows. First, electricity charges consist of basic charges and electricity charges. The basic charge is a predetermined charge portion that does not depend on the power consumption of the month. On the other hand, the electricity charge is a charge portion determined according to the power consumption of the month. And, in the demand rate system, it is important to keep the basic rate low because the ratio of the basic rate to the electricity rate is high.

Here, the basic charge is determined using the maximum demand power (demand value) within the past one year. In particular, as the demand value, the maximum 30-minute demand value in one month is used. The 30-minute demand value indicates an average used power for 30 minutes. For example, if the 30-minute demand value is a high value even once, the one-year basic charge from the next month is set to a high level based on the high value. In addition, there is also a contract form in which the power demander is penalized when the average power or the amount of power consumption at a predetermined time temporarily exceeds the reference regardless of whether the demand rate system is used or not. In this manner, by urging the power demander to reduce the demand value, stable power supply can be achieved. Moreover, in order for each power demander to keep the electricity rate low, it is important to control so that the average power or the amount of power consumption in a predetermined time does not increase.

Returning to FIG. 1, the operation of each component will be described in detail below.

As described above, the storage battery 120 is connected to the power line 130 connected to the power network 20 through the power receiving facility 110. Then, the power measurement unit 140 measures the power supplied from the power network 20 to the power line 130. The power is determined by the product of the current flowing through the power line 130 and the voltage.

The calculating means 150 is a predicted value of average power in a target time zone from a predetermined time t ₀ to a predetermined time t ₁ (for example, after 30 minutes) based on the measurement result of the power measuring means 140 or The predicted value of the power consumption in the target time zone is calculated. The predicted value is calculated for each reference time in the target time zone.

The following describes the processing performed for each of the case where the calculation unit 150 calculates the predicted value of the average power [W] in the target time zone and the case where the calculated value of the power consumption [Wh] of the target time zone is calculated. Do.

FIG. 9 is a diagram showing an example of the average power and the actual value of the average power in the target time zone. In this figure, from time t ₀ to a predetermined show some changes in the actual value of the power consumption up to the current time by a solid line. Moreover, in this figure, transition of the predicted value of average power (average power consumption) calculated at each time is shown by a broken line.

The calculating unit 150 acquires information indicating the power measured by the power measuring unit 140 at predetermined time intervals. Then, by integrating the power consumption from time t _0, to calculate the actual value of the power consumption up to the current time. Then, by dividing the actual value of the power consumption amount by the elapsed time from the time t _0, and calculates the average value of the power consumption up to that time. Calculating means 150 may be regarded as the predicted value of the average power as the target time zone average values obtained (i.e. the average power from time t ₀ to time t _{0 +} t _1), further consumption at the current time The prediction may be calculated taking into account the power. For example, if the power consumption at the current time is large, the predicted value can be calculated large, and if the power consumption is small, the predicted value can be calculated small.

The calculation unit 150 calculates the above-described predicted value every reference time (for example, every 10 seconds).

In the example of this figure, although the example which calculates the estimated value of average power was demonstrated, it is not limited to this. For example, the predicted value of the average power may be obtained by dividing the predicted value of the power consumption obtained by the method described later by the time.

FIG. 3 is a diagram showing an example of actual values of power consumption in a target time zone and predicted values of power consumption. In this figure shows the time t ₀ to a predetermined, certain changes in the power consumption up to the current time by a solid line. The broken line is a straight line obtained by extrapolating the solid line. Although the example which calculates the predicted value of power consumption using the figure below is demonstrated, it is not limited to this.

Calculating means 150 obtains information indicating the power power measuring means 140 is measured to calculate the actual value of the power consumption from time t _0. Then, based on the actual value of the power consumption from time t _0, to calculate the predicted value of the time t ₁ by elapsed power consumption at the time t _{0 +} t ₁ from time t _0. Calculating means 150, for example, linear approximation as shown by the broken line in the figure the transition of power consumption from time t ₀ to the current time, the value indicated by the approximation straight line at time t _{0 +} t ₁ be the predicted value it can. Further, calculating means 150, the actual value of the power consumption from time t ₀ to the current time, to calculate the power consumption per unit time divided by the elapsed time to the current time from the time t _0, is obtained The predicted value may be calculated by multiplying the power consumption amount per unit time by the time t ₁ . In addition, the calculation unit 150 may calculate the prediction in consideration of the slope of the power consumption at the current time. For example, when the slope of the power consumption is large, the predicted value can be calculated large, and when the slope of the power consumption is small, the predicted value can be calculated small.

Incidentally, the predicted value of the power consumption amount predicted in the manner described above, converted into power consumption by dividing the time t ₀ at time t _{0 +} t ₁ to time (the length of target time zone) for a period of time t ₁ It may be a predicted value of the average power of the target time zone.

The power control system 10 may perform processing using any one of the above-described predicted value of average power and the predicted value of power consumption. In addition, unless there is particular mention, the "predicted value" appearing below means the predicted value of the average power in a target time zone. However, the same process can be performed by using the predicted value of the power consumption of the target time zone instead of the predicted value of the average power.

Battery control means 160 controls storage battery 120. Specifically, the battery control means 160 acquires the predicted value calculated for each reference time by the calculation means 150 each time. Then, battery control means 160 discharges storage battery 120 when the predicted value exceeds a predetermined reference value. The reference value is stored, for example, in storage means 180 in advance, and can be read out and used by battery control means 160.

When the predicted value is a reference value of average power, the reference value is a value indicating power. Further, in the present embodiment, the reference value is, for example, a value smaller than the maximum demand power (demand value) within the past one year. By doing so, the power consumer can avoid the demand value rising further and the basic charge being set higher. In addition, when the calculation means 150 calculates the predicted value of power consumption, a reference value is a value which shows power consumption. Reference value of power consumption is a value smaller than the value obtained by converting, for example the power consumption by multiplying the time t ₁ to the demand value.

The operation of the battery control means 160 when the predicted value is less than the reference value is not particularly limited, but the battery control means 160 charges, for example, the storage battery 120 when the predicted value is less than the reference value. Also, battery control means 160 may charge storage battery 120 at a timing when, for example, the power unit price is lower than the reference. The timing when the unit price of electricity is lower than the reference is stored in advance in storage means 180 as information indicating the range of time, such as from a certain time to a certain time, and battery control means 160 reads it and uses it. Can. By doing this, it is possible to effectively use the power whose unit price is cheap and to reduce the power charge. In this case, the battery control means 160 may not charge the storage battery 120 when the predicted value is less than or equal to the reference value.

Also, the battery control means 160 may charge the storage battery 120 when the predicted value is equal to or less than the reference value and the power unit price is lower than the reference. Battery control means 160 does not charge storage battery 120 at a timing when the power unit price is higher than the reference. By doing this, it is possible to effectively use the power whose unit price is cheap and to reduce the power charge.

FIG. 4 is a diagram showing a flow of a control method of the storage battery 120 according to the present embodiment. In this control method, the predicted value of the average power in the target time zone or the predicted value of the power consumption of the target time zone based on the measurement result of the power measuring unit 140 that measures the power supplied from the power network 20 to the power line 130 Is calculated (step S10). Then, when the predicted value exceeds the reference value (Yes in step S20), the battery control means 160 discharges the storage battery 120 (step S30). Further, the predicted value is calculated for each reference time in the target time zone. Details will be described below.

First, the power measurement unit 140 measures the power supplied from the power network 20 to the power line 130. The power measurement unit 140 may perform measurement at all times, or may perform measurement based on a control signal from the control device 30.

The calculation unit 150 acquires the measurement result at predetermined time intervals from the power measurement unit 140, and calculates the predicted value of the average power or the predicted value of the power consumption of the target time zone (step S10). The method by which the calculating means 150 calculates the predicted value is as described above. The calculation means 150 calculates a predicted value every predetermined reference time. Then, the calculated predicted value is processed by the battery control means 160 as follows.

The battery control means 160 determines whether the predicted value calculated by the calculation means 150 exceeds the reference value (step S20). If the battery control means 160 determines that the predicted value exceeds the reference value (Yes in step S20), the battery control means 160 discharges the storage battery 120 (step S30). Then, when the predetermined control stop operation on the control device 30 is not performed (No in step S40), the determination is repeated for the predicted value calculated by the calculation unit 150. By discharging the storage battery 120 when the predicted value exceeds the reference value, the power consumption can be suppressed. As a result, it is possible to avoid the increase in power consumption in the target time zone.

On the other hand, when it is determined that the predicted value is less than the reference value (No in step S20), the storage battery 120 is not discharged. And when control stop operation is not performed (No of step S40), determination is repeated about the predicted value calculated by the calculation means 150 continuously. As described above, when it is determined that the predicted value is less than the reference value (No in step S20), the battery control unit 160 may charge the storage battery 120.

When it is determined that the predicted value exceeds the reference value and discharge is started from storage battery 120, storage battery 120 may continue discharging until it is determined that the predicted value is less than the reference value next.

Also, when one target time zone has passed, the next target time zone starts subsequently. That is, the actual value of the power consumption returns to 0 Wh, and the process is continued. For example, the length of one target time zone is 30 minutes, and the prediction value of the average power or the power consumption is reset every 30 minutes, and calculation of the prediction value and control of the storage battery 120 are continued. That is, time t ₀ is set at an interval of 30 minutes, and a predicted value in each target time zone is calculated.

The repetition of the calculation and determination of the predicted value ends when a predetermined control stop operation is performed on the control device 30 (Yes in step S40).

Next, the operation and effects of the present embodiment will be described. According to the power control system 10, the control device 30, and the control method according to the present embodiment, it is possible to suppress an increase in the demand value by calculating the prediction value in a predetermined time and performing the determination. As a result, it is possible to prevent an increase in electricity charges.

Second Embodiment
FIG. 5 is a diagram illustrating the hardware configuration of the power control system 10 according to the second embodiment. The power control system 10 according to the present embodiment is the same as the power control system 10 according to the first embodiment except for the points described below.

In the present embodiment, a distribution board 303 b and a distribution board 303 c are further provided downstream of the power conversion facility 302 (opposite to the electric power grid 20) via the distribution board 303 a. Also, the measuring instrument 308 is provided between the distribution board 303 a and the distribution board 303 b. Power reception facility 110 includes power conversion facility 302 and distribution board 303 a. The storage battery 120 and the load 301a are connected to the distribution board 303a via the distribution board 303b.

In the present embodiment, the measuring instrument 308 measures the current [A] (instantaneous value) in the power consumed by the load 301a and the storage battery 120 and the voltage [V] (instant value) in the power consumed by the load 301a and the storage battery 120. It is used to measure. The measuring instrument 308 is used to obtain the power value [W] (instantaneous value) and the amount of power [Wh] of the power (power consumption) consumed by the load 301 a and the storage battery 120, and as the power measuring means 140 Function.

The configuration according to the present embodiment is effective, for example, when fluctuations in power consumption occur particularly with respect to a load connected to a specific distribution board.

Next, the operation and effects of the present embodiment will be described. In this embodiment, the same operation and effect as the first embodiment can be obtained.

Third Embodiment
FIG. 6 is a diagram showing an outline of a power control system 10 according to the third embodiment. The power control system 10 according to the present embodiment is the same as the power control system 10 according to the first embodiment or the second embodiment except for the points described below.

The power control system 10 according to the present embodiment further includes an operation control unit 170. The operation control unit 170 switches the battery control unit 160 between the operation state and the non-operation state based on information indicating at least one of the history of the measurement result of the power measurement unit 140, the date and time, the season, the weather, and the air temperature. Details will be described below.

FIG. 7 is a diagram showing a flow of a control method of the storage battery 120 according to the third embodiment. The control method according to the present embodiment will be described with reference to this drawing.

First, operation control means 170 determines whether or not battery control means 160 is to be operated (step S50). The method of determination made by the operation control means 170 will be described later. If the operation control unit 170 determines that the battery control unit 160 is not operated (No in step S50), the battery control unit 160 is inactivated. That is, the calculation of the predicted value by the calculation unit 150 and the determination of the predicted value by the battery control unit 160 are not performed. Then, the determination as to whether to operate the battery control means 160 is repeated.

On the other hand, when the operation control means 170 determines that the battery control means 160 is to be operated (Yes in step S50), the battery control means 160 is put in the operating state, and the processes after step S10 are the same as in the first embodiment. To be done.

The determination result as to whether or not to operate the battery control means 160 may be updated at predetermined time intervals. That is, the operating state or the non-operating state of the battery control means 160 may be determined based on the result of one determination within a predetermined time. For example, the operation control unit 170 may determine whether to operate the battery control unit 160 for each target time zone.

When the battery control means 160 is operated at all times, frequent discharge of the storage battery 120 may occur. Then, when the electrical energy stored in the storage battery 120 is discharged, the control of the battery control means 160 can no longer discharge the storage battery 120. In order to avoid such a situation, it is conceivable to use a storage battery having a large capacity, but this increases the cost of equipment. Therefore, unnecessary discharge of the storage battery 120 can be suppressed by switching the operation state and the non-operation state of the battery control means 160 by the operation control means 170. That is, the battery control means 160 can be operated only when there is a risk that the demand value will be particularly high.

A method of determining whether the operation control means 170 operates the battery control means 160 will be described below. Specifically, the operation control unit 170 determines that the battery control unit 160 is to be operated at a timing when a high power consumption amount is predicted, and determines that the battery control unit 160 is not to be operated at other timings. Then, information indicating the determination result is generated. The battery control unit 160 acquires information indicating the determination result from the operation control unit 170, and controls the storage battery 120 only when it is determined to operate.

The operation control unit 170 determines whether to operate the battery control unit 160 based on information indicating at least one of the history of measurement results of the power measurement unit 140, the date and time, the season, the weather, and the temperature. In each of the following examples (determination method 1 to determination method 7), the information indicating the determination criteria used for determination whether the operation control means 170 operates the battery control means 160 is, for example, connected to the operation control means 170. It is held in advance in the storage means 182, and the operation control means 170 can read it out and use it. Moreover, each of the following determination methods may be used alone or in combination of two or more. When used in combination, for example, the operation control means 170 determines that the battery control means 160 is to be operated when it is applied when the battery control means 160 is operated by at least one of a plurality of determination methods.

(Judgment method 1)
When the operation control unit 170 determines whether to operate the battery control unit 160 based on the information indicating the history of the measurement results of the power measurement unit 140, for example, the processing can be performed by the following method. When the power demander is a business operator, if the power consumption on one operation day (business day) is high, the power consumption on the next operation day is also predicted to be high. Therefore, in the history of the measurement results of the power measurement unit 140, the operation control unit 170 determines that the battery control unit 160 is to be operated when the power consumption amount of the previous operation day is larger than a predetermined reference. The information indicating the history of the measurement result of the power measurement unit 140 is stored, for example, in the storage unit 182, and can be read out and used by the operation control unit 170.

(Judgment method 2)
When the operation control unit 170 determines whether to operate the battery control unit 160 based on the history of measurement results of the power measurement unit 140 and information indicating the date and time, processing can be performed by, for example, the following method. The operation control unit 170 extracts measurement results of the date and time corresponding to the date and time of the determination target from the history of the measurement result of the power measurement unit 140. Then, when the extracted measurement result is larger than a predetermined reference, it is determined that the battery control means 160 is operated. Here, the date and time corresponding to the date and time to be determined means, for example, the same time on the same day of the same week (for example, the same week within one year) one year ago to be determined. Show. By doing so, judgment can be made reflecting the past trend of the power demander depending on time.

(Method 3 of judgment)
When the operation control means 170 determines whether to operate the battery control means 160 based on the information indicating the date and time, processing can be performed, for example, by the following method. When the facility that consumes power is an office building or the like, the daytime on weekdays is the timing when high power consumption is predicted. Therefore, the operation control means 170 determines that the battery control means 160 is to be operated when the date to be determined corresponds to a predetermined date and time (for example, from 9 o'clock to 17 o'clock on weekdays).

(Judgment method 4)
When the operation control means 170 determines whether to operate the battery control means 160 based on the information indicating the season, it can be processed, for example, by the following method. In the case where the power demander is a business operator and has a facility that operates only in a specific season, the operating season is the timing at which high power consumption is predicted. For example, in the case of a skating rink, high power consumption is expected in winter. Therefore, the operation control means 170 determines that the battery control means 160 is to be operated when the season at the time of determination corresponds to a predetermined season. The season is determined based on the date of month.

(Method 5 of judgment)
When the operation control unit 170 determines whether to operate the battery control unit 160 based on the information indicating the date and time and the weather, for example, processing can be performed by the following method. When the facility that consumes power is an office building or the like, high consumption of electricity is expected due to the use of cooling on a sunny day of summer. Therefore, operation control means 170 determines that battery control means 160 is to be operated when the date to be determined corresponds to a predetermined date (for example, August) and it is clear. The operation control means 170 can access, for example, the server of the weather information providing service to obtain information indicating the weather.

(Method 6 of judgment)
When the operation control unit 170 determines whether to operate the battery control unit 160 based on the information indicating the air temperature, for example, the processing can be performed by the following method. When the facility that consumes power is an office building or the like, high power consumption is expected due to the use of cooling if the temperature is particularly high and by the use of heating if the temperature is particularly low. Therefore, the operation control unit 170 determines that the battery control unit 160 is to be operated when the temperature of the date to be determined is outside the range of the predetermined reference. The operation control means 170 can obtain information indicating the temperature, for example, from the information provided by the weather information providing service. Further, the operation control means 170 may obtain the temperature at that time from a thermometer at the place of the facility that consumes power.

If the date and time to be determined is a future date and time, expected weather or expected temperature can be used as the above-mentioned weather or temperature. The operation control means 170 can access, for example, the server of the weather information provision service to obtain information indicating the expected weather and the expected temperature.

(Judgment method 7)
The operation control means 170 can also determine whether to operate the battery control means 160 based on the date and time and information indicating the specific condition of the power consumer, in which case, for example, it can be processed by the following method . The information indicating the specific condition of the power consumer refers to, for example, information indicating the time zone of replacement of the shift system, information indicating the production amount of the production plan, and the facility when the facility consuming the power is a factory or the like. It is information indicating an operation rate. At the shift timing of the shift system, high power consumption is expected at a specific time, such as moving the crane to move to a specific place all at once just before the change. In addition, the operation rate of equipment varies according to the production plan, and high operation rate and high power consumption are expected on the day when a large amount of production is planned. Therefore, the operation control means 170 determines that the battery control means 160 is to be operated when the time to be determined corresponds to the time zone of change. Further, the operation control means 170 determines that the battery control means 160 is to be operated when the production amount of the production plan is larger than a predetermined reference. Then, the operation control means 170 determines that the battery control means 160 is to be operated when the operation rate of the facility is higher than a predetermined reference.

In addition, when the facility that consumes power is a commercial facility or the like, the information indicating the specific condition of the power consumer is the information indicating the day when the sale or the event is held. Many customers are expected on sale and event days, and high power consumption is expected. Therefore, the operation control means 170 determines that the battery control means 160 is operated when the day to be determined corresponds to a sale or event day.

On the other hand, the information indicating the specific condition of the power demander may be information indicating a holiday or a long vacation period of the business who is the power demander. In that case, high power consumption is not expected. Therefore, the operation control unit 170 determines that the battery control unit 160 is not operated when the day to be determined corresponds to the holiday or the long vacation period of the business.

The information indicating the specific condition of the power consumer is, for example, input by the user in advance and held in the storage unit 182, and the operation control unit 170 can read and use it.

Although the example of the determination method has been described above, other determination methods may be used without being limited to the above.

The operation control means 170 is an operation state of the battery control means 160 in advance based on information indicating at least one of a history of measurement results of the power measurement means 140, a date and time, a season, an expected weather, and an expected air temperature. And information indicating a schedule that defines the non-operating state may be generated. In that case, the battery control means 160 acquires information indicating the schedule from the operation control means 170, and takes the operating state and the non-operating state based on the schedule.

FIG. 8 is a diagram showing a configuration of a communication system of the power control system 10 according to the third embodiment. In the example of this figure, the power measurement means 140 is connected to the first communication network 410, and the operation control means 170 is connected to the second communication network 420. The first communication network 410 and the second communication network 420 are connected via the gateway device 40. The first communication network 410 is, for example, a local network, and the second communication network 420 is, for example, the external Internet.

When the operation control means 170 is connected to the second communication network 420 and the battery control means 160 is connected to the first communication network 410 as in the example of this figure, the operation control means 170 performs the second communication. The operating state and the non-operating state of the battery control means 160 are switched via the network 420.

In addition, the operation control means 170 may be connected via a plurality of battery control means 160 and the second communication network 420. The plurality of battery control means 160 control, for example, storage batteries 120 of power consumers different from each other. In this case, the operation control means 170 determines whether or not to operate each battery control means 160 using determination criteria that differ depending on the business mode of each power demander and the facility where power is consumed. good.

Note that although the example in which the calculation unit 150 is connected to the first communication network 410 is shown in this figure, the calculation unit 150 may be connected to the second communication network 420. That is, the calculation means 150 may obtain the measurement result from the power measurement means 140 via the second communication network 420 and calculate the predicted value. Further, although the example in which the battery control means 160 is connected to the first communication network 410 is shown in this figure, the battery control means 160 may be connected to the second communication network 420. That is, the battery control means 160 may control the storage battery 120 via the second communication network 420. Further, although the example in which the operation control means 170 is connected to the second communication network 420 is shown in this figure, the operation control means 170 may be connected to the first communication network 410. The operation control means 170 may be included in the control device 30.

Next, the operation and effects of the present embodiment will be described. In this embodiment, the same operation and effect as the first embodiment can be obtained. In addition, when the operation control means 170 switches the operation state and the non-operation state of the battery control means 160, the frequency of discharge of the storage battery 120 is reduced. Therefore, it is possible to avoid a situation where the amount of electric energy of storage battery 120 is insufficient particularly in a necessary situation.

Fourth Embodiment
The outline of the power control system 10 according to the fourth embodiment can be shown in the same manner as FIG. Moreover, the flow of the control method of the storage battery 120 which concerns on this embodiment can be shown similarly to FIG. The power control system 10 according to the present embodiment is the same as the power control system 10 according to the third embodiment except that the operation control unit 170 predicts the magnitude of the power consumption.

In the present embodiment, the operation control means 170 estimates the power consumption predicted based on the information indicating at least one of the history of the measurement result of the power measurement means 140, the date and time, the season, the weather, and the air temperature (hereinafter The power consumption of the battery is referred to as “expected power consumption” or the power consumption (hereinafter referred to simply as “expected power consumption” or “predicted power consumption”), based on the size of the battery. The control means 160 is switched between the operating state and the non-operating state.

A detailed description will be given below, including a method of estimating power consumption or the amount of power consumption. In the control method according to the present embodiment, the operation control unit 170 determines whether to operate the battery control unit 160 (step S50). When the operation control unit 170 determines that the battery control unit 160 is not operated (No in step S50), the battery control unit 160 is inactivated. On the other hand, when the operation control means 170 determines that the battery control means 160 is to be operated (Yes in step S50), the battery control means 160 is put in the operating state, and the processes after step S10 are the same as in the first embodiment. To be done.

In step S50 of the present embodiment, the operation control means 170 calculates predicted power consumption or predicted power consumption and uses it for determination. Here, the predicted power consumption may be an instantaneous value of the date to be determined, or may be an average value of the power consumption of a predetermined time zone (for example, a target time zone) including the date to be determined. Good. Further, the predicted power consumption is the power consumption of a predetermined time zone (for example, a target time zone) including the date and time to be determined.

In the present embodiment, the history of the measurement result of the power measuring unit 140 used by the operation control unit 170 to calculate the predicted power consumption or the predicted power consumption, information indicating at least one of date and time, season, weather, and air temperature , And stored in the storage means 182. In addition, the operation control means 170 may access a server of the weather information providing service to acquire information indicating an expected weather or an expected temperature.

In step S50, the operation control unit 170 first reads out from the storage unit 182 the value of the basic power consumption corresponding to the date and time to be determined. The value of the basic power consumption is a value included in the history of the measurement results of the power measurement unit 140, and is, for example, the value of the power consumption of the time corresponding to the time to be determined on the previous operation day.

Next, the operation control unit 170 determines whether high power consumption is expected at the date and time to be determined. As a specific example, for example, the determination is performed by any of the determination methods 1 to 7 described in the third embodiment.

In the present embodiment, the correction value of the predicted power consumption is associated with each determination result of each determination method. The information indicating the determination method and the information indicating the correction value can be determined based on the result of statistical analysis in advance, and can be stored in the storage unit 182. The operation control means 170 can read this out from the storage means 182 and use it. In each determination method, the determination result may be divided into a plurality of stages according to the predicted increase in power consumption. As the correction value, for example, a positive value is associated with the determination result in which high power consumption is expected, and a negative value is associated with the determination result in which low power consumption is expected. The determination result in which high power consumption is expected is, in other words, the determination result in the case where the battery control means 160 is operated in the above-mentioned determination method 1 to determination method 7.

The operation control unit 170 determines whether high power consumption is expected at the date and time to be determined, and adds the correction value corresponding to the obtained determination result to the basic power consumption. By doing so, predicted power consumption can be calculated more accurately.

In the above, the method of calculating the predicted power consumption by the operation control unit 170 adding the correction value as the power consumption to the basic power consumption has been described, but the present invention is not limited thereto. The operation control unit 170 can calculate the predicted power consumption by adding the correction value as the power consumption to the basic power consumption, as described above. In addition, the operation control unit 170 multiplies the predicted power consumption calculated as described above by the length of a predetermined time zone (for example, a target time zone) including the date and time of the above-described determination target, and the predicted consumption is estimated. The amount of power (estimated power consumption) may be calculated.

Then, the operation control means 170 switches the battery control means 160 to the operation state when the predicted power consumption or the predicted power consumption amount exceeds a predetermined value. The predetermined value is stored in advance in the storage unit 182, which can be read out and used by the operation control unit 170.

Note that the operation control means 170 controls the battery control means 160 based on information indicating at least one of the history of measurement results of the power measurement means 140, the date and time, the season, the weather, and the air temperature in the operation state of the battery control means 160. May change the reference value used to make the determination (step S20) for the predicted value. Specifically, the size of the predicted power consumption or the predicted power consumption is predicted based on information indicating at least one of the history of the measurement result of the power measurement unit 140, the date and time, the season, the weather, and the air temperature. Then, the operation control means 170 changes the reference value based on the predicted predicted power consumption or the size of the predicted power consumption.

For example, the operation control means 170 determines that the predicted power consumption or the predicted power consumption predicted based on the information indicating at least one of the history of the measurement result of the power measurement means, the date and time, the season, the weather and the air temperature is larger. Increase the reference value. By doing so, discharge continues in a state where the amount of power consumption is high, and the electric energy of the storage battery is not exhausted. Specifically, the operation control unit 170 can obtain the reference value by multiplying the predicted power consumption calculated as described above or the predicted power consumption by a predetermined coefficient. The coefficients are stored in advance in the storage means 182, and can be read out and used by the operation control means 170. The battery control means 160 acquires the reference value generated by the operation control means 170 and uses it for the determination of step S20.

Conversely, the motion control means 170 determines the smaller the predicted power consumption or the predicted power consumption estimated based on the information indicating at least one of the history of the measurement result of the power measurement means, the date and time, the season, the weather and the air temperature. The reference value may be increased. By doing so, excessive discharge can not be performed in a state where the risk of increasing the demand value is low. On the other hand, when the amount of power consumption is unexpectedly increased, the battery control means 160 discharges the battery, thereby suppressing an increase in the demand value.

Further, the information indicating the predicted power consumption or the predicted power consumption may be information indicating which of the plurality of power consumptions or levels (levels) of the power consumption are classified. In that case, the above-mentioned correction value is a value indicating how many minutes the level is to be raised. The predicted power consumption or each step of the predicted power consumption is linked to the reference value, and the reference value is switched according to the step.

Further, in the present embodiment, the battery control means 160 may charge the storage battery 120 at a timing when the predicted value of the average power or the predicted value of the power consumption is predicted to be lower than the reference. The timing at which the predicted value of the average power or the predicted value of the power consumption is predicted to be lower than the reference can be determined, for example, as the timing at which the predicted power consumption or the predicted power consumption calculated as described above becomes lower than the reference. Here, the information indicating the reference can be stored in advance in the storage unit 182, and can be read out and used by the operation control unit 170. The timing at which the predicted value of the average power or the predicted value of the power consumption is predicted to be lower than the reference is generated by the operation control means 170 as information indicating a time range such as, for example, from a certain time to a certain time The battery control means 160 can acquire it and use it. For example, the operation control means 170 may charge the storage battery 120 at the timing when the predicted power consumption or the predicted power consumption calculated as described above becomes lower than the reference.

Next, the operation and effects of the present embodiment will be described. In this embodiment, the same operation and effect as the first embodiment can be obtained. In addition, since the operation control means 170 controls the operation of the battery control means 160 based on the predicted power consumption, unnecessary discharge of the storage battery 120 is reduced. Therefore, it is possible to avoid a situation where the amount of electric energy of storage battery 120 is insufficient particularly in a necessary situation.

Fifth Embodiment
The outline of the power control system 10 according to the fifth embodiment can be shown in the same manner as FIG. The power control system 10 according to the present embodiment is the same as the power control system 10 according to the first embodiment except for the points described below.

In the present embodiment, the battery control means 60 determines whether or not the average value of the average power or the power consumption value in the target time zone satisfies a predetermined reference every time one target time zone passes. Update the reference value according to the result. Specifically, when the actual power value of the average power of the target time zone or the actual power value of the power consumption of the target time zone exceeds a predetermined performance reference value, the battery control means 60 refers to the performance reference value. Set as a value. Then, in the next target time zone, the battery control means 160 performs step S20 described in the first embodiment using the updated reference value.

When the actual value used for the determination is the actual value of average power, the actual reference value is, for example, a demand value at the start of the handling time zone, which is a value higher than the reference value. In addition, when the actual value used for the determination is the actual value of the power consumption, the actual performance reference value is a value converted to the power consumption by multiplying the demand value at the start of the handling time zone by the length of the handling time zone It is. The performance reference value is previously stored in the storage unit 180, and can be read out and used by the battery control unit 160.

As described in the first embodiment, when the demand value is updated, that is, when the maximum demand power is updated, a one-year basic charge is determined based on the new demand value. Therefore, it is important not to exceed the new demand value in the target time zone. Therefore, unnecessary discharge of storage battery 120 can be suppressed by changing the reference value based on the latest demand value.

As described above, the battery control means 60 sets (updates) the actual performance reference value as a new reference value when the actual performance value exceeds a predetermined actual performance reference value. On the other hand, if the measured value does not exceed the measured reference value, the reference value is not changed even if the actual value exceeds the reference value. When the reference value is updated, the battery control means 160 causes the storage means 180 to store (update) the actual value determined to exceed the actual value reference value as a new actual result reference value.

The reference value may be made to match the demand value. That is, in the above, the reference value may match the actual result reference value. In this case, when the actual value exceeds the reference value, the actual value is set as a new reference value.

In addition, when the performance value exceeds a predetermined performance reference value, the battery control means 60 may set (update) the performance value as a new reference value.

In addition, the method of the present embodiment may be applied to the power control system 10 according to the third embodiment or the fourth embodiment. In that case, the operation control means 170 may determine whether the average value or the actual value of the power consumption meets a predetermined standard. Specifically, the operation control unit 170 acquires the actual value from the battery control unit 160, and reads the actual value reference value from the storage unit 182. Then, when the actual value exceeds the actual reference value, the operation control means 170 outputs the actual reference value to the battery control means 160 as a reference value. Then, using the reference value acquired from the operation control means 170, the battery control means 160 processes the next target time zone.

Next, the operation and effects of the present embodiment will be described. In this embodiment, the same operation and effect as the first embodiment can be obtained. In addition, by updating the reference value, charging / discharging of storage battery 120 can be controlled using the reference value reflecting the demand value at that time.

In the sequence diagrams and flowcharts used in the above description, a plurality of steps (processes) are described in order, but the execution order of the steps performed in each embodiment is not limited to the order described. In each embodiment, the order of the illustrated steps can be changed within the scope of the content. Moreover, the above-mentioned each embodiment can be combined within the range in which the contents do not contradict each other.
