Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same constituents will be referred to with the same numerals, and the description thereof will not be repeated.

(First embodiment)
A power adjustment system, an information processing device, an information processing method, and a program according to the first embodiment of the present invention will be described below.
FIG. 1 is a diagram conceptually showing a system configuration of a power adjustment system 1 according to an embodiment of the present invention.
In each of the following drawings, a configuration of a portion not related to the essence of the present invention is omitted and not shown.

The power adjustment system 1 includes a storage battery 40, a PCS (Power Conditioner System) 42, a control device 50, and a first smart meter M1.

The electric power system 10 and the load 12 are electrically connected by the electric power line 20, and electric power is supplied from the electric power system 10 to the load 12.
The load 12 is at least one of various electric devices such as an air conditioner, a lighting device, a refrigerator, a television, a microwave oven, a dryer, a personal computer, a game machine, a telephone, a water heater, an electric vehicle, and a plug-in hybrid vehicle. It is not particularly limited.

Although FIG. 1 shows a system including the storage battery 40, the present invention is not limited to this, and may be a system including a power generation device (not shown) or a system including both the storage battery 40 and the power generation device.

The frequency of the power system 10 (hereinafter, also referred to as “system frequency”) changes according to the output of a power generation facility (not shown) in the power system 10 and the power consumption of a consumer load. In addition to the power generation equipment and the load that consumes the power, the power storage equipment that charges and discharges the power also exists in the power system 10. In recent years, power generation devices and power storage devices have become widespread in general households, and in order to match the demand and supply of electric power of the electric power system 10 and keep the system frequency constant, a large number of energy-related devices of various scales and various forms are related. It is necessary to control the devices (power generation device and power storage device) in an integrated manner.

A control signal for supply and demand adjustment for performing control for holding the system frequency at the reference value is transmitted from the management device 3 at the central power feeding command center. By the integrated input/output control of the storage battery 40 and the power generation device of each consumer according to the control signal, the power adjustment system 1 can adjust the power supply and demand.

The control device 50 of each consumer receives the control signal from the management device 3 of the central power feeding command station via the server 5 of the intermediate supply of the storage battery, and controls the charging/discharging of the storage battery 40 (or the output of the power generation device). To do. The control signal includes, for example, an LFC (Load Frequency Control) signal, but is not limited to this.

The PCS 42 includes a first sensor S1 (also referred to as a system CT) that measures a current value of power flowing through the power line 20, an internal sensor S0 that measures a current value of power input to and output from the power line 20 from the PCS 42, and is not illustrated. Based on the PV (PhotoVoltaics) sensor (also called PVCT) that measures the current value of the electric power output from the power generator, the measured value obtained from the sensor, the control signal from the management device 3 of the central power feeding command station, and the like. The charge/discharge of the storage battery 40 and the output of the power generator are controlled. It should be noted that the actual power control is performed by converting it to a power value using a system voltage value measuring sensor separately and using the voltage and the current (first sensor S1, internal sensor S0, PVCT, etc.). In the following description of calibration, implicitly, this voltage sensor is also collectively referred to as a current sensor. That is, when talking about the calibration of the current sensor, it means the calibration of the power value related to the current sensor, for example, including the voltage sensor in the PCS 42.

Here, if the accuracy of power control of each consumer by the PCS 42 is low, there is a possibility that the supply and demand balance of the power system 10 may be affected. As described above, for example, the charge/discharge amount of the storage battery 40 is controlled by the PCS 42 based on the current values of the three sensors. In particular, the internal sensor S0 used in the PCS 42 often has a low cost, and its measurement accuracy may be low. It is also known that each sensor causes an error in the measured value depending on the ambient temperature. Further, accuracy deterioration due to aging deterioration of the sensor can be considered.

In this way, it is desirable that the calibration of each sensor be performed regularly. The information processing apparatus 100 according to the embodiment of the present invention particularly provides means for easily and regularly calibrating the internal sensor S0 of the PCS 42.

In the example of FIG. 1, the PCS 42 and the control device 50 are described separately, but these may be configured physically or logically separately, or physically or logically integrally. Good.

The information processing device 100 may be realized by either one of the control device 50 and the PCS 42, or a device in which the PCS 42 and the control device 50 are integrated, and the functions of the information processing device 100 by the PCS 42 and the control device 50, respectively. May be shared and realized.

In the present embodiment, the information processing device 100 is realized by the control device 50.

As will be described later, the information processing apparatus 100 corrects the instruction value indicating the power input/output to/from the power line 20 to be controlled based on the measurement value of the internal sensor S0, instead of calibrating the internal sensor S0. Calculate the coefficient.

In the configuration in which the information processing device 100 is realized by the control device 50, the control device 50 transmits the instruction value to the PCS 42 by multiplying the correction value by the instruction value that instructs the PCS 42 to input and output the power to and from the power line 20. .. Then, the internal sensor S0 is calibrated by controlling the electric power according to the corrected instruction value received by the PCS 42.

In the configuration in which the information processing apparatus 100 is realized by the PCS 42, the internal sensor S0 is calibrated by the PCS 42 multiplying the instruction value received from the control device 50 by the correction coefficient and using the multiplied value for power control.

FIG. 2 is a diagram showing an example of the configuration of a computer 80 that realizes the information processing apparatus 100 (each device: the control device 50, the PCS 42, or the integrated device of the PCS 42 and the control device 50) of the present embodiment. .. Further, the first smart meter M1 and the second smart meter M2 of this embodiment are also realized by the computer 80.
The first smart meter M1 of the present embodiment corresponds to the second watt hour meter, and the second smart meter M2 corresponds to the first watt hour meter.

The computer 80 of the present embodiment includes a CPU (Central Processing Unit) 82, a memory 84, a program 90 that realizes the constituent elements of FIG. 2 loaded in the memory 84, a storage 85 that stores the program 90, and an I/O (Input). /Output) 86, and a network connection interface (communication I/F 87).

The CPU 82, the memory 84, the storage 85, the I/O 86, and the communication I/F 87 are connected to each other via a bus 89, and the CPU 82 controls the entire information processing apparatus 100. However, the method of connecting the CPU 82 and the like to each other is not limited to bus connection.

The memory 84 is a memory such as a RAM (Random Access Memory) or a ROM (Read Only Memory). The storage 85 is a storage device such as a hard disk, SSD (Solid State Drive), or memory card.

The storage 85 may be a memory such as a RAM or a ROM. The storage 85 may be provided inside the computer 80, or may be provided outside the computer 80 and connected to the computer 80 by wire or wirelessly if the computer 80 is accessible. Alternatively, it may be detachably provided in the computer 80.

When the CPU 82 reads the program 90 stored in the storage 85 into the memory 84 and executes the program 90, each function of each unit of the information processing apparatus 100 of each embodiment can be realized.

The I/O 86 controls input/output of data and control signals between the computer 80 and other devices. Further, the I/O 86 may control the input/output of data to/from a reading/writing device (not shown) of another recording medium.

The communication I/F 87 is a network connection interface for communicating between the computer 80 and an external device. The communication I/F 87 may be a network interface for connecting to a wired line or a network interface for connecting to a wireless line. For example, a computer 80 that realizes the information processing device 100 (for example, the control device 50) is connected to the server 5 of the intermediate storage battery supply via the network 7 by the communication I/F 87. Alternatively, the computer 80 that realizes the information processing device 100 (for example, the control device 50) wirelessly communicates with the first smart meter M1 and the second smart meter M2 by the communication I/F 87.

Each component of the information processing apparatus 100 according to each embodiment of the present invention is realized by an arbitrary combination of hardware and software of the computer 80 of FIG. It will be understood by those skilled in the art that there are various modified examples of the realizing method and the apparatus. The functional block diagram showing the information processing apparatus of each embodiment described below shows a block of a logical functional unit, not a configuration of a hardware unit.

Returning to FIG. 1, the control device 50 is, for example, an EMS (Energy Management System), and has various functions and performances depending on the storage battery 40 to be controlled, and is not limited.

As described above, the control device 50 has a function of communicating with the server 5 for which the storage battery is supplied via the network 7, and may control the storage battery 40 according to an instruction from the server 5. There are various communication means and corresponding protocols between the control device 50 and the server 5, and the connection is made without any limitation, while ensuring security by predetermined authentication and encryption processing.

The first smart meter M1 is supplied to the consumer from the electric power company. The first smart meter M1 includes a power meter (not shown) and a communication unit (not shown). The first smart meter M1 measures the consumption amount of electric power supplied to the consumer's home via the power transmission/distribution network (or the amount of electric power flowing backward from the consumer's home). The meter reading data measured by the watt-hour meter is periodically (for example, every 30 minutes) by wireless communication from the first smart meter M1 to the server (not shown) of the power company via the so-called A route by the communication unit. Sent to. This meter reading data is used for calculation of electricity charges and the like.

The communication unit of the first smart meter M1 further communicates with a communication device (for example, a HEMS (Home Energy Management System) or the control device 50 of the present embodiment) in a customer's home via a so-called B route. You can

The communication method of the B route is not particularly limited, but, for example, a specific low power wireless system using the 920 MHz band, for example, a communication system based on a communication standard such as Wi-SUN, or IEEE802.80 such as Zigbee®. A communication system of a wireless communication standard operating on 15.4 can be used. In order to secure the security, the route B is subjected to a predetermined authentication procedure before the connection is established.

The first smart meter M1 can wirelessly communicate with the control device 50 through the B route, for example, and can transmit the measurement value regarding the power from the first smart meter M1 to the communication device in the customer's home.

The meter reading data transmitted from the first smart meter M1 to the control device 50 is not limited, but, for example, at least one of the instantaneous power value and the integrated power amount, and the time when each value is measured (or calculated) is indicated. It includes the time information shown.

In the power adjustment system 1 of the present embodiment, the second smart meter M2 is further installed on the power line 22 through which power is input and output from the PCS 42 to the power line 20. The second smart meter M2 has only to include a power meter (not shown) and a communication unit (not shown), and may be, for example, a smart meter, but is not limited thereto.

FIG. 3 is a functional block diagram logically showing the configuration of the information processing device 100 according to the embodiment of the present invention.
The information processing apparatus 100 of this embodiment includes a measurement value acquisition unit 102, an instruction value acquisition unit 104, and a calculation unit 106.
The measurement value acquisition unit 102 acquires a measurement value related to the power flowing in the power line 20 between the power system 10 and the load 12.
The instruction value acquisition unit 104 acquires an instruction value indicating the power to be input to and output from the storage battery 40 in the power line 20.

When the electric power input/output to/from the storage battery 40 is controlled and input/output to/from the electric power line 20 according to the instruction value, the calculation unit 106 outputs a measured value (electric power [W] output from the PCS 42 or input to the PCS 42). A correction coefficient for correcting the indicated value is calculated so that the power [W]) becomes the corresponding indicated value.

In this specification, "acquisition" means that the device itself acquires data or information stored in another device or a storage medium (active acquisition), for example, requests or inquires to another device. Receiving, reading and accessing other devices or storage media, and inputting data or information output from other devices to its own device (passive acquisition), for example, distribution (or , Sending, push notification, etc.) and/or receiving data or information. It also includes selecting and acquiring from the received data or information, or selecting and receiving the distributed data or information.

The measurement values acquired by the measurement value acquisition unit 102 are exemplified below.
(1) Accumulated electric energy (Wh) of electric power input/output to/from the power line 20 from the PCS 42 measured by the second smart meter M2
(2) Instantaneous value (W) of electric power input/output to/from the power line 20 from the PCS 42 measured by the second smart meter M2
(3) Current value of electric power flowing to the electric power system 10 side of the electric power line 20 (measurement value of the first sensor S1)
(4) Current value of power flowing to the load 12 side of the power line 20 (measurement value of the second sensor S2 in FIG. 10)
(5) Integrated electric energy (Wh) measured by the first smart meter M1
(6) Instantaneous power value (W) measured by the first smart meter M1

The measurement value of the second smart meter M2 is transmitted from the second smart meter M2 to the control device 50 by wireless communication via the B route. Therefore, in another embodiment in which the information processing device 100 is realized by the PCS 42, the measurement value of the second smart meter M2 is transmitted from the control device 50 to the PCS 42 after being transmitted to the control device 50 by wireless communication via the B route. It is transmitted by wired or wireless communication and is acquired by the measurement value acquisition unit 102.

Further, in an embodiment described later, the measurement value of the first sensor S1 or the second sensor S2 of FIG. 11 is input to the PCS 42. Therefore, in the mode in which the information processing device 100 is realized by the control device 50, after being input to the PCS 42, the information is transmitted from the PCS 42 to the control device 50 by wired or wireless communication and is acquired by the measurement value acquisition unit 102.

The instruction value acquired by the instruction value acquisition unit 104 is a value transmitted from the control device 50 to the PCS 42. In the present embodiment, since the information processing device 100 is realized by the control device 50, the instruction value acquisition unit 104 acquires the instruction value held by the control device 50. In the form in which the information processing device 100 is realized by the PCS 42, the instruction value acquisition unit 104 receives the instruction value from the control device 50.

Further, as described above, in the present embodiment in which the information processing apparatus 100 is realized by the control device 50, the instruction value is multiplied by the correction coefficient, and the corrected instruction value is transmitted from the control device 50 to the PCS 42. In the mode in which the information processing apparatus 100 is realized by the PCS 42, the instruction value is multiplied by a correction coefficient to make a correction, and the PCS 42 controls charging/discharging of the storage battery 40 based on the corrected instruction value. The electric power input/output to/from becomes equal to the indicated value.

The calculation unit 106 calculates the correction coefficient for each predetermined period.
The time interval at which the measurement value acquisition unit 102 acquires the measurement value may be the predetermined period, but it does not necessarily have to be the same. For example, the measurement value acquisition unit 102 may acquire the measurement value every 30 minutes, and the calculation unit 106 may calculate the correction coefficient every 60 minutes. In that case, the calculation unit 106 calculates the correction coefficient using the two measurement values acquired by the measurement value acquisition unit 102 every 30 minutes.

In the present embodiment, the predetermined period is 30 minutes, but is not limited to this. For example, it may be 45 minutes, 60 minutes, or the like, but it is desirable that the correction coefficient be reviewed at a timing when an error exceeding the allowable range occurs in the measurement value of each sensor due to the temperature difference around the PCS 42 with the passage of time. For example, if the predetermined period is set to 3 hours from 9:00 to 12:00 in the morning, the temperature change during this period is large and the measured value may have an error exceeding the allowable range. It is better to update the correction coefficient within a relatively short span.

In the present embodiment, the second smart meter M2 measures the electric power input/output from the PCS 42 to the electric power line 22, and transmits the measured value to the control device 50 via the B route. In the present embodiment, the timing at which the measurement value is transmitted from the second smart meter M2 to the PCS 42 is when the measurement value is requested from the PCS 42 to the second smart meter M2, but the timing is not limited to this. The second smart meter M2 may transmit the measurement value to the control device 50 at predetermined intervals.

The measurement value acquisition unit 102 acquires, as the measurement value, the integrated electric energy for each predetermined period from the second smart meter M2. The configuration in which the measurement value acquisition unit 102 acquires the electric power instantaneous value from the second smart meter M2 will be described in an embodiment described later.

In the present embodiment, wireless communication is performed between the second smart meter M2 and the control device 50 by a specific low power wireless system that uses the 920 MHz band (hereinafter referred to as 920 MHz communication). Therefore, communication cannot be performed while other devices are performing 920 MHz communication in the vicinity, or communication quality is not guaranteed, so there is room to read measurement values at time intervals and retry in the event of an error. preferable.

The integrated electric energy transmitted from the second smart meter M2 is a meter reading value of the second smart meter M2 at the time of transmission. Therefore, the measurement value acquisition unit 102 calculates the difference (W) between the previous read value (30 minutes before) and the current read value, and uses the time information of each value to calculate the accumulated power amount for a predetermined period (30 minutes). Calculate (Wh).

Hereinafter, in this specification, the description of the process of calculating the integrated electric energy from the meter reading value acquired by the measured value acquisition unit 102 will be omitted, and the “integrated electric energy” will be described as the measured value acquired by the measured value acquisition unit 102. To do.

In the present embodiment, when the integrated power amount exceeds a predetermined value, the calculation unit 106 integrates the integrated power amount for each predetermined period (for example, 30 minutes) and the corresponding instruction value for a predetermined period to perform an integration instruction. A correction coefficient that satisfies a predetermined relationship with the value is calculated.

Here, the predetermined value is a predetermined multiple (for example, 100 times) of the number of significant digits of the measurement value of the second smart meter M2.
In other words, when a measurement value within a range in which the measurement error of the second smart meter M2 is acceptable is obtained, the measurement value is used to calculate the correction coefficient. For example, when the number of significant digits of the second smart meter M2 is 10 Wh, when the measured value is 100 Wh, the error may be about 10%. When the measured value is 1000 Wh, the error is about 1%. In this embodiment, a measurement value that exceeds a predetermined multiple of the number of significant digits of the second smart meter M2 is used for calculation.

Therefore, it is possible to provide the power adjustment system 1 that satisfies the required level by setting the predetermined value in accordance with the required accuracy (allowable range of error, etc.).

If the above-mentioned predetermined period is short, the value of the integrated electric energy of the measurement value of the second smart meter M2 may not exceed a predetermined multiple (for example, 100 times) of the number of significant digits of the second smart meter M2. .. Therefore, it is preferable to extend the predetermined period to a length in which the measured value of the second smart meter M2 exceeds a predetermined multiple of the number of significant digits of the second smart meter M2.

Therefore, when the integrated electric energy does not exceed the predetermined value after the elapse of the predetermined period, the integration is further continued, and the correction coefficient is calculated after the integrated electric energy exceeds the predetermined value.

In addition, it is preferable that the measurement timing be set such that the measurement value is acquired at least during a time period in which the temperature change is large (the temperature change per unit time is equal to or more than the first threshold value) in one day. The measurement value acquisition timing may be scheduled in advance, or the schedule may be updated according to the temperature change or the measurement value.

For example, when the temperature change is large, the measurement timing interval is set to be short, and when the temperature change is not so large (the temperature change per unit time is less than the second threshold value (first threshold value>second threshold value)). The measurement timing interval may be set long, and if the measurement value is less than the predetermined value, the measurement timing interval may be set long, and if the measurement value exceeds the predetermined value, the measurement timing interval may be set short. ..
When the measurement value acquired in the predetermined period or schedule determined in advance does not exceed the predetermined value, the integration may be continued and the correction coefficient may be calculated after the time when the predetermined value is exceeded.

Further, in the present embodiment, an example in which the control device 50 uses one instruction value x will be described, but in another example, the instruction value x is, for example, the charge of the storage battery 40 in order to adjust the power for consumer use. It may include a plurality of instruction values such as an instruction value x1 for controlling discharge and an instruction value x2 for controlling charging/discharging of the storage battery 40 for supply/demand adjustment.

The integrated instruction value C(z) for the integrated time z of the instruction value x is expressed by the following equation (1). The cumulative time z is a predetermined period or a time (for example, 30 minutes) in which the cumulative amount of power is accumulated. When the integrated time of the integrated electric energy exceeds the predetermined period, z becomes the integrated time (for example, 38 minutes when 8 minutes exceeds 30 minutes of the predetermined period).

Here, if the integrated electric energy before calibration of the internal sensor S0 includes an error α, a correction coefficient for correcting the error α is A. As shown in the following equation (2), when the integrated instruction value C(z) is multiplied by the calculated correction coefficient A, the measured value D(z) measured by the second smart meter M2 is the indicated value. Is equal to

Here, the correction coefficient A is 1/error α. The error α is indicated by a value obtained by dividing the measurement value D(z) measured by the second smart meter M2 before correction by the integration instruction value C(z). Therefore, since the correction coefficient A is 1/error α, it is a value obtained by dividing the integration instruction value C(z) by the measurement value D(z) measured by the second smart meter M2 before correction.
The calculation method of the correction coefficient is not limited to this, and the calculation unit 106 obtains the correction coefficient A that satisfies the predetermined relationship between the integrated electric energy (measured value) D(z) and the integrated instruction value C(z). May be.

In addition to the above example, the predetermined relationship is a value obtained by rounding down a value less than the number of significant digits of the measured value, a value rounded up or a value rounded off, and the integrated instruction value C(z) multiplied by the correction coefficient A. An example in which the measured values D(z) measured by the smart meter M2 are equal is also included.

Hereinafter, the computer program according to the embodiment of the present invention will be described.

The computer program 90 according to the present embodiment causes the computer 80 for realizing the information processing apparatus 100 to acquire a measurement value related to the power flowing through the power line 20 between the power system 10 and the load 12 from the storage battery 40 to the power line. When the power input/output to/from the storage battery 40 is controlled and input/output to/from the power line 20 in accordance with the procedure for acquiring the instruction value indicating the power to be input/output to/from the power line 20, the measured value becomes the corresponding instruction value. Therefore, the procedure for calculating the correction coefficient for correcting the indicated value is executed, and in the procedure for acquiring the measured value, the accumulated electric energy for a predetermined period (30 minutes) from the second smart meter M2. In the procedure of acquiring and calculating (Wh), when the integrated power amount exceeds a predetermined value, the integrated power amount for each predetermined period (for example, 30 minutes) and the corresponding instruction value are integrated for each predetermined period. It is described that a correction coefficient that satisfies a predetermined relationship with the integrated instruction value is calculated.

The computer program 90 of the present embodiment may be recorded in a recording medium readable by the computer 80. The recording medium is not particularly limited, and various forms are conceivable. The program 90 may be loaded from the recording medium into the memory 84 of the computer 80, or may be downloaded into the computer 80 via a network and loaded into the memory 84.

The recording medium for recording the computer program 90 includes a medium that can be used by the non-transitory tangible computer 80, and the program code readable by the computer 80 is embedded in the medium. When the computer program 90 is executed on the computer 80, it causes the computer 80 to execute the following information processing method for realizing the information processing apparatus 100.

An information processing method of the information processing apparatus 100 of the present embodiment configured as above will be described below.
FIG. 4 is a flowchart showing an example of the operation of the information processing device 100 of this embodiment.
The information processing method according to the embodiment of the present invention is an information processing method of the information processing apparatus 100, and is an information processing method executed by the computer 80 that realizes the information processing apparatus 100.
In the information processing method according to the present embodiment, the information processing apparatus 100 acquires a measurement value related to the power flowing in the power line 20 between the power system 10 and the load 12 (steps S101 and S107), and the storage battery 40 to the power line 20. When a power value input/output to/from the storage battery 40 is controlled and input/output to/from the power line 20 according to the instruction value, the measured value indicates a corresponding instruction. A correction coefficient for correcting the indicated value is calculated so as to obtain the value (step S113), and further, in step S101 and step S107, the integrated electric energy (Wh) for the predetermined period (30 minutes) is calculated from the second smart meter M2. In the acquisition and calculation, when the integrated power amount exceeds a predetermined value (YES in step S109), the integrated power amount for each predetermined period (for example, 30 minutes) and the corresponding instruction value are set for each predetermined period. And a correction coefficient satisfying a predetermined relationship with the integration instruction value accumulated in (step S111, step S113).

The details will be described below.
This flowchart is started when the information processing apparatus 100 is activated, and then repeatedly executed.
First, the measurement value acquisition unit 102 acquires the integrated electric energy from the second smart meter M2 for each predetermined period (step S101). The acquired integrated electric energy is stored in the measured value storage unit 112 of the storage device 110 in FIG. 5A together with the time information.

Next, the instruction value acquisition unit 104 acquires the instruction value x (step S103). This instruction value x is, as a function of the control device 50, various control signals received from the server 5 of the storage battery supply, the power consumption of the load 12 of the customer, the charge amount of the storage battery 40, and PV (not shown). Output, system CT, PVCT, measurement values of the internal sensor S0, and the like.

The instruction value x is stored in the instruction value storage unit 116 of the storage device 110 of FIG. 6A in association with the time information. In this example, the instruction value for each minute is stored, but the present invention is not limited to this.

Then, after the start or after the previous correction coefficient calculation (step S115), until the lapse of 30 minutes (NO in step S105), the instruction value acquisition unit 104 repeats the acquisition of the instruction value x. For example, the instruction value x may be acquired every one minute or the like and stored in the instruction value storage unit 116.

Alternatively, it may be stored in the instruction value storage unit 116 when the instruction value x changes by a predetermined value or more. The accumulated instruction value may be converted into an instruction value for the accumulated time based on the instruction value x and the time information. For example, if the instruction value xa at 12:00 and the instruction value xb at 12:10 are stored and the integration time is from 12:00 to 12:32, the integration instruction value is (xa×10/60+xb X22/60) x60.

Then, after 30 minutes have passed (YES in step S105), the measurement value acquisition unit 102 receives the integrated electric energy (kWh) from the second smart meter M2 (step S107). Then, the calculation unit 106 calculates the accumulated electric energy (Wh) for 30 minutes based on the previous and present measured values of the accumulated electric energy (kWh) and their time information, and calculates the time information (the measured value of this time). Associated time) and is stored in the integrated power value storage unit 114 of the storage device 110 in FIG.

Specifically, the measurement value acquisition unit 102 subtracts the measurement value (meter reading value) at 12 o'clock from the measurement value (meter reading value) at 12:30, calculates the measurement time interval from the time information, and measures every 30 minutes. It is converted to the integrated electric energy (Wh).

Then, the calculation unit 106 determines whether the calculated integrated electric energy exceeds a predetermined value (step S109). When the integrated electric energy exceeds a predetermined value (YES in step S109), the calculation unit 106 integrates the instruction values for the integration time to calculate the integrated instruction value, and associates the time information with the time information, as shown in FIG. It is stored in the integrated instruction value storage unit 118 of the storage device 110 of b) (step S111).

On the other hand, if the integrated electric energy does not exceed the predetermined value in step S109 (NO in step S109), the process returns to step S103, and the instruction value acquisition unit 104 acquires the instruction value (step S103). When returning from step S109, since 30 minutes have already passed from the time when the correction coefficient for success was calculated (YES in step S105), the calculation unit 106 acquires the measurement value from the second smart meter M2.

Here, the integrated electric energy that did not exceed the predetermined value is further integrated. In step S109, the integrated electric energy in the meantime is calculated from the measured value obtained when the correction coefficient was calculated last time and the measured value acquired this time. Then, the integration is continued until the integrated electric energy exceeds a predetermined value.

Then, if the integrated electric energy exceeds the predetermined value in step S109 (YES in step S109), the integrated instruction value is calculated in step S111 as described above. At this time, when the measured values are accumulated over a predetermined period, the accumulated time is calculated from the time information, the instruction value for the accumulated time is accumulated, and the accumulated instruction value is calculated.

Using the thus calculated integrated electric energy and integrated instruction value, the calculation unit 106 corrects the instruction value using the correction coefficient A so that the integrated electric energy becomes the integrated instruction value, The correction coefficient A is calculated (step S113). Specifically, the correction coefficient A is calculated by dividing the integrated instruction value by the integrated electric energy. Then, the calculation unit 106 corrects the instruction value x by multiplying the calculated correction coefficient A by the instruction value x, and transmits the corrected instruction value x to the PCS 42 (step S115). Then, the process returns to step S101 and the present process is repeated.

Although not shown, the PCS 42 receives the instruction value x from the control device 50 and controls the electric power input/output to/from the power line 20 using the received instruction value x. As a result, the error of the internal sensor S0 is calibrated, and the electric power that matches the indicated value x is input to and output from the electric power line 20.

The flowchart of this embodiment is an example, and the order of the procedure of each step is not limited to the above flow. The measurement value acquisition procedure of step S101 and the instruction value acquisition procedure of step S103 do not necessarily have to be performed in a series of procedures. Each may be executed independently or in parallel.
Moreover, the procedure of step S111, step S113, and step S115 does not necessarily have to be performed in a series of procedures. Each may be executed independently.

As described above, in the information processing device 100 of the power adjustment system 1, the calculation unit so that the measurement value acquired by the measurement value acquisition unit 102 becomes the corresponding instruction value acquired by the instruction value acquisition unit 104. The correction coefficient A is calculated by 106.

In the present embodiment, the measured value is the integrated power amount, and the correction coefficient is calculated using the integrated power amount acquired every predetermined period. The predetermined period is set so that the error of the measured value due to the temperature change does not exceed the allowable range, and the integrated electric energy is set to a value exceeding the number of significant digits of the measured value.

According to this configuration, when the internal sensor S0 is calibrated, it can be corrected in consideration of the effective number of digits of the reference measurement value, so that the accuracy is improved. Further, by setting the predetermined value of the integrated electric energy according to the required accuracy, it is possible to provide the electric power adjustment system 1 that satisfies the required level.
As described above, according to the power adjustment system 1 and the information processing device 100 of the present embodiment, it is possible to realize highly accurate power control in the consumer.

(Second embodiment)
Next, a second embodiment of the present invention will be described below.
The power adjustment system 1 and the information processing device 100 according to the present embodiment have the same configurations as those of the above embodiments, and therefore will be described with reference to FIGS. 1 and 3.
The information processing apparatus 100 according to the present embodiment is different from the above-described embodiment in that an instantaneous power value is acquired as a measurement value from the second smart meter M2 and the correction coefficient is calculated using the instantaneous power value.

In the above-described embodiment, it is necessary to wait for the calculation of the correction coefficient at least until the integrated electric energy exceeds a predetermined value (a predetermined multiple of the number of significant digits). Therefore, when the power consumption is small, the interval between the correction coefficient calculation timings may become long. If the correction coefficient calculation interval is long, there is a high possibility that a large temperature change will occur during that interval, and an error may occur in the internal sensor S0 due to the temperature change.
Therefore, in this embodiment, it is possible to set the correction coefficient calculation timing to an arbitrary time by using the instantaneous value.

In the present embodiment, the measurement value acquisition unit 102 acquires, from the second smart meter M2, at least one power instantaneous value of the power input/output to/from the power line 22 as a measurement value.
The instruction value acquisition unit 104 respectively acquires at least one instruction value when the measurement value acquisition unit 102 acquires at least one power instantaneous value.
The calculation unit 106 calculates the correction coefficient A using at least one electric power instantaneous value acquired from the second smart meter M2 and the instruction value corresponding to the electric power instantaneous value.

The calculation unit 106 calculates an average value of a plurality of power instantaneous values and an average value of a plurality of instruction values, respectively. Then, the calculation unit 106 calculates a correction coefficient in which the average value of the calculated power instantaneous values and the average value of the corresponding instruction values satisfy a predetermined relationship. Alternatively, the calculation unit 106 may calculate an integrated value of a plurality of electric power instantaneous values acquired from the second smart meter M2. Then, the calculation unit 106 may calculate a correction coefficient that satisfies a predetermined relationship between the calculated integrated value of the power instantaneous value and the integrated value of the corresponding instruction value.

Specifically, the calculation unit 106 calculates the correction coefficient A by dividing the average value of the instruction values by the average value of the power instantaneous values. Alternatively, the calculation unit 106 calculates the correction coefficient A by dividing the integrated value of the instruction value by the integrated value of the instantaneous power value. Alternatively, the calculation unit 106 may calculate the correction coefficient A by dividing at least one instruction value by at least one power instantaneous value.

The details will be described below.
The timing at which the measurement value acquisition unit 102 acquires the instantaneous power value from the power line 20 is, for example, a continuous timing within a predetermined time of a predetermined period (for example, 10 times every few seconds in the first minute of 30 minutes). ) Is preferred.

It is desirable that the instruction value acquisition unit 104 acquires the instruction value at the same timing as the measurement value acquisition unit 102 acquires the measurement value. However, it does not always have to be the same.

The calculated average value includes a value obtained by statistically processing a plurality of values such as an average value and a median value. If the measured value acquired by the measured value acquisition unit 102 is 0, the measured value is excluded from the calculation. If the difference between the measured value acquired by the measured value acquisition unit 102 and the corresponding instruction value is equal to or more than a predetermined ratio with respect to the instruction value, the measured value is excluded from the calculation. When the measured value is 0, a value smaller than the number of significant digits of the measured value may be 0 in consideration of the error of the measured value.

When the measured value is excluded, the measured value acquisition unit 102 may acquire the measured value until a predetermined number or more than the predetermined integrated output value is acquired. At this time, for example, when a predetermined number of valid measurement values cannot be acquired even after a predetermined time (for example, 3 minutes or more) has elapsed after the first valid measurement value was acquired, a time interval is provided and then the process is performed again. May start.

Further, the number of measurement values for calculating the average value may be changed according to the measurement values. When the fluctuation of the measurement value is small and almost constant, and the standard deviation thereof is less than the first predetermined value (first predetermined ratio), the number of the measurement values is reduced (for example, 3), and the interval of the acquisition timing is increased (for example, the time). Every 10 seconds).

On the other hand, when the fluctuation of the measured value is large and the standard deviation thereof is equal to or larger than the second predetermined value (second predetermined ratio) (where, the second predetermined value (second predetermined ratio)>the first predetermined value (first predetermined ratio). )), the number may be increased (for example, 20), and the acquisition timing interval may be shortened (for example, every 1 second).

Ａ＝Ｅ／Ｆ ・・・式（５） The calculation unit 106 calculates the average value E of the instruction value x, the average value F of the measurement value y of the second smart meter M2, and the correction coefficient A using the following equations.

A=E/F... Formula (5)

Here, in the above formula (5), the correction coefficient A is calculated by dividing the average value E of the instruction value x by the average value F of the measurement value y of the second smart meter M2.
The calculation method of the correction coefficient is not limited to this, and the calculation unit 106 sets the correction coefficient A that satisfies the predetermined relationship between the average value F of the measurement values y of the second smart meter M2 and the average value E of the instruction value x. May be asked.

In addition to the above example, the predetermined relationship is equal to a value obtained by rounding down a value less than the significant digit of the measurement value, a value rounded up or a value rounded off, and a value obtained by multiplying the average value E of the instruction value x by the correction coefficient A. Including examples. Further, when using the integrated value, an expression excluding n on the right side of Expressions (3) and (4) is used. When using the average value, the number of measurements may be increased in consideration of the error of the second smart meter M2 until the value of the average value becomes a predetermined value or more.

Hereinafter, the computer program according to the embodiment of the present invention will be described.
In the information processing apparatus 100 according to the present embodiment, the CPU 82 of the computer 80 executes various processing operations corresponding to computer programs, so that the various units described above are realized as various functions.

The computer program of the present embodiment causes a computer for realizing the information processing apparatus 100 to acquire a measurement value related to the electric power flowing through the electric power line 20 between the electric power system 10 and the load 12 from the storage battery 40 to the electric power line 20. Procedure for obtaining an instruction value indicating the electric power to be input/output, when the electric power input/output from the storage battery 40 is controlled according to the instruction value and input/output to/from the power line 20, the measured value becomes the corresponding instruction value. In order to execute the procedure for calculating the correction coefficient for correcting the instruction value, the second procedure for measuring the instantaneous power value of the power input/output to/from the power line 22 in the procedure for acquiring the measured value is described. In the procedure of acquiring at least one electric power instantaneous value as a measurement value from the smart meter M2 and acquiring the instruction value, in the procedure of acquiring and calculating at least one instruction value when the at least one electric power instantaneous value is acquired, It is described that the correction coefficient is calculated using at least one electric power instantaneous value acquired from the second smart meter M2 and an instruction value corresponding to the electric power instantaneous value.

Further, in the computer program of the present embodiment, in the calculation procedure, the average value of the plurality of electric power instantaneous values acquired from the second smart meter M2 and the average value of the plurality of instruction values satisfy a predetermined relationship. It is described to execute the procedure for obtaining the correction coefficient.

The recording medium for recording the computer program 90 includes a medium that can be used by the non-transitory tangible computer 80, and the program code readable by the computer 80 is embedded in the medium. When the computer program 90 is executed on the computer 80, it causes the computer 80 to execute the following information processing method for realizing the information processing apparatus 100.

An information processing method of the information processing apparatus 100 of the present embodiment configured as above will be described below.
FIG. 8 is a flowchart showing an example of the operation of the information processing device 100 of this embodiment.
The information processing method according to the embodiment of the present invention is an information processing method of the information processing apparatus 100, and is an information processing method executed by the computer 80 that realizes the information processing apparatus 100.
In the information processing method according to the present embodiment, the information processing apparatus 100 acquires a measurement value related to the power flowing in the power line 20 between the power system 10 and the load 12 (step S203), and inputs/outputs the storage battery 40 to/from the power line 20. When the instruction value indicating the electric power to be obtained is acquired (step S207) and the electric power input/output from the storage battery 40 is controlled according to the instruction value and input/output to/from the power line 20, the measured value becomes the corresponding instruction value. As described above, a correction coefficient for correcting the indicated value is calculated (step S217), and further, in step S203, at least the measured value is output from the second smart meter M2 that measures the instantaneous power value of the power input/output to/from the power line 22. One electric power instantaneous value is acquired, in step S207, at least one instruction value when at least one electric power instantaneous value is acquired, and in step S217, at least one electric power acquired from the second smart meter M2. The correction coefficient is calculated using the instantaneous value and the instruction value corresponding to the instantaneous power value (step S217).

Further, in the information processing method of the present embodiment, the information processing apparatus 100 corrects the average value of the plurality of instantaneous power values acquired from the second smart meter M2 and the average value of the plurality of instruction values so as to satisfy a predetermined relationship. Including determining the coefficient.

The details will be described below.
This flowchart is started when the information processing apparatus 100 is activated, and then repeatedly executed, for example, every predetermined period (30 minutes or the like). Here, an example in which the correction coefficient is calculated using the average value of a plurality of power instantaneous values will be described.
First, the measurement value acquisition unit 102 sets the counter i to 1 (step S201). This counter i indicates the effective number of pieces of data that are acquired from the second smart meter M2 and for which the average value is to be calculated, and is incremented until a predetermined number n (for example, 10) necessary for calculating the average value is reached. R. (Here, i and n are natural numbers of 1 or more.)

The measurement value acquisition unit 102 receives the instantaneous power value from the second smart meter M2 (step S203). The instantaneous power value that has been successfully received (YES in step S205) is stored in the instantaneous power value storage unit 122 of the storage device 110 in FIG. 9A in association with the time information. Then, the instruction value acquisition unit 104 acquires the instruction value x and stores it in the instantaneous power value storage unit 122 of FIG. 9A in association with the corresponding measured value. Then, the counter i is incremented (step S209), and it is determined whether the number of data exceeds a predetermined number n (step S211).

If the reception fails in step S205 (NO in step S205), the process returns to step S203, and the measurement value acquisition unit 102 acquires the measurement value again. Further, in step S205, it can be determined whether or not the measured value is valid. For example, it is determined whether the measured value is not 0, and whether or not the difference between the measured value and the instruction value is less than the predetermined ratio, and if all the conditions are satisfied, the process may proceed to step S207. If even one condition is not satisfied, the process returns to step S203. Further, in the determination that the measured value is not 0, it may be determined that the value smaller than the number of significant digits of the measured value is 0 in consideration of the error of the measured value.

Then, until the number of data (counter i) exceeds the predetermined number n, if the counter i is n or less (NO in step S211), the process returns to step S203, the measured value and the instruction value are collected, and the instantaneous power value storage unit 122 is used. Remember.

When the number of data (counter i) exceeds the predetermined number n (YES in step S211), the calculation unit 106 calculates the average value F of a plurality of power instantaneous values by using the formula (4) and associates it with the time information. The average value storage unit 124 of the storage device 110 of FIG. 9B is stored (step S213). Further, the calculation unit 106 calculates the average value E of the plurality of instruction values corresponding to the instantaneous power value using the equation (4), and associates the time information and the average value F of the instantaneous power values with the average value of the instruction values. E is stored in the average value storage unit 124 (step S215).

The calculation unit 106 refers to the average value storage unit 124 and calculates the correction coefficient A by using the equation (5) so that the average value F of the instantaneous power values becomes the average value E of the instruction values (step S5). S217). The calculated correction coefficient A is stored in the correction coefficient storage unit 126 of the storage device 110 of FIG. 10 in association with the time information.

Then, the calculation unit 106 multiplies the calculated correction coefficient A by the instruction value x to correct the instruction value x, and transmits the corrected instruction value x to the PCS 42 (step S219). Then, the process returns to step S201, and this process is repeated every predetermined period (for example, every 30 minutes).

Although not shown, the PCS 42 receives the instruction value x from the control device 50 and controls the electric power input/output to/from the power line 20 using the received instruction value x. As a result, the error of the internal sensor S0 is calibrated, and the electric power that matches the indicated value x is input to and output from the electric power line 20.

As described above, in the information processing device 100 of the power adjustment system 1, the calculation unit so that the measurement value acquired by the measurement value acquisition unit 102 becomes the corresponding instruction value acquired by the instruction value acquisition unit 104. The correction coefficient A is calculated by 106.

In the present embodiment, the measurement value is an electric power instantaneous value, and the correction coefficient calculation process is performed as an average value of the measurement values acquired at consecutive timings within a predetermined time of a predetermined period.
Since the measurement value is acquired from the second smart meter M2 by wireless communication, there is a possibility that the measurement value cannot be acquired due to a communication error or the like. According to the present embodiment, a plurality of measurement values are acquired and the average value is used, so that data loss due to a communication error can be dealt with in a short period of time.

Further, in the above-described embodiment in which the integrated electric energy is used as the measurement value, there is a possibility that the interval between the correction coefficient calculation timings becomes long when the power consumption is small. If the correction coefficient calculation interval is long, there is a high possibility that a large temperature change will occur during that interval, and an error may occur in the internal sensor S0 due to the temperature change. According to the present embodiment, the correction coefficient calculation timing can be set to an arbitrary time.

As described above, according to the present embodiment, it is possible to achieve the same effect as that of the above-described embodiment, and further, it is possible to efficiently realize highly accurate power control in the consumer.

(Third Embodiment)
Next, a third embodiment of the present invention will be described below.
FIG. 11: is a figure which shows notionally the system configuration of the power adjustment system 1 which concerns on embodiment of this invention.
The power adjustment system 1 of the present embodiment differs from the above-described embodiment in that it has a first sensor S1 and a second sensor S2 instead of the second smart meter M2 as the measurement value acquisition means.

In the present embodiment, the power line 20 includes a first power line 20a between the power system 10 and the PCS 42 and a second power line 20b between the PCS 42 and the load 12.
The PCS 42 is electrically connected between the power line 20 and the storage battery 40 or the power generation device. The PCS 42 inputs and outputs electric power controlled according to the instruction value to the electric power line 20.
The PCS 42 controls the discharge of the storage battery 40 when the instruction value is set to a negative value, and controls the charging of the storage battery 40 when the instruction value is set to a positive value.

The first sensor S1 and the second sensor S2 are clamp type current sensors (CT: Current Transformer). The first sensor S1 measures the current value of the power flowing through the first power line 20a. The second sensor S2 measures the current value of the power flowing through the second power line 20b.
The PCS 42 is electrically connected to the first sensor S1 and the second sensor S2 and acquires a current value from each sensor.

The information processing apparatus 100 according to the present embodiment has the same configuration as that of the above embodiment, and will be described with reference to FIG.
The information processing apparatus 100 of the present embodiment is different from the above-described embodiment in that the measurement value acquisition unit 102 as the measurement value acquisition unit acquires the measurement value from the first smart meter M1, the first sensor S1, and the second sensor S2. The difference is that the calculation unit 106 has a configuration for calculating the correction coefficient based on

In the information processing apparatus 100 of the present embodiment, the measurement value acquisition unit 102 acquires at least one current value of the power flowing through the first power line 20a as a measurement value from the first sensor S1, and further, a voltmeter (not shown). The instantaneous power value of the power flowing through the first power line 20a is calculated using the voltage value measured by.
Further, the measurement value acquisition unit 102 acquires at least one current value of the power flowing through the second power line 20b as a measurement value from the second sensor S2, and further, the voltage measured by the voltmeter in the PCS 42 (not shown). The value is used to calculate the power instantaneous value of the power flowing through the second power line 20b.

Each power instantaneous value is acquired by the measurement value acquisition unit 102 at successive timings (for example, 10 times every few seconds in the first 1 minute of 30 minutes) within a predetermined time of a predetermined period, as in the above embodiment. To be done.
In this way, the measurement value acquisition unit 102 acquires, from the first sensor S1 and the second sensor S2, at least one electric power instantaneous value for each of the first sensor S1 and the second sensor S2 as a measurement value.

Hereinafter, in the present specification, the process of calculating the power instruction value based on the current value acquired by the measurement value acquisition unit 102 from the first sensor S1 or the second sensor S2 and the voltage value acquired from the voltmeter (not shown). The description thereof will be omitted, and the “instantaneous power value” will be described as a measurement value acquired by the measurement value acquisition unit 102 from the first sensor S1 or the second sensor S2.

Furthermore, the instruction value acquisition unit 104 acquires at least one instruction value when at least one measurement value of the first sensor S1 and the second sensor S2 is acquired. It is desirable that the instruction value acquisition unit 104 acquires the instruction value at the same timing as the measurement value acquisition unit 102 acquires the measurement value. However, it does not always have to be the same.

The calculation unit 106 calculates the correction coefficient by using at least one electric power instantaneous value for each of the first sensor S1 and the second sensor S2 and the instruction value corresponding to the measured value.
In the present embodiment, an example will be described in which the correction coefficient is calculated using the average value of the plurality of instruction values corresponding to the average value of the plurality of power instantaneous values. Further, the correction coefficient may be calculated using one instruction value corresponding to one electric power instantaneous value, or using the integrated value of a plurality of indicated values corresponding to the integrated value of a plurality of instantaneous electric power values. The correction coefficient may be calculated.

The calculating unit 106 calculates the average values G1 and G2 of the plurality of instantaneous power values of the first sensor S1 and the second sensor S2, and the average value E of the plurality of instruction values x corresponding to the plurality of measured values, respectively.
For example, in charge/discharge control of the storage battery 40, the instruction value x has a negative value during discharge control of the storage battery 40, and the instruction value x has a positive value during charge control of the storage battery 40.

In the power adjustment system 1, if there is no reverse flow to the power system 10, the measured value of the second sensor S2 (instantaneous power value) is the measured value of the first sensor S1 (instantaneous power value) during discharge control of the storage battery 40. ) And the instantaneous electric power value (negative) measured by the internal sensor S0. Further, during the charge control of the storage battery 40, the measurement value of the first sensor S1 (power instantaneous value) is the same as the measurement value of the second sensor S2 (power instantaneous value) and the power instantaneous value (positive) measured by the internal sensor S0. Is equal to the sum.

Further, when the electric power input/output controlled to the power line 22 by the value of the internal sensor S0 is different from the instruction value x due to the error of the internal sensor S0, the instruction value x is multiplied by the correction coefficient A and given to the PCS 42. The power input/output from the PCS 42 to the power line 22 can be made equal to the instruction value x.

From these, the calculation unit 106 subtracts the average value G1 of the first sensor S1 from the calculated average value G2 of the second sensor S2, as shown in the following equation (6). The correction coefficient A is calculated so that the value E is obtained.
A=E/(G2-G1)... Formula (6)

In the above formula (6), the correction coefficient A is calculated by dividing the average value E of the indicated values by G2-G1. The method of calculating the correction coefficient is not limited to this. The calculation unit 106 may obtain a correction coefficient that satisfies a predetermined relationship between G2-G1 and the average value E of the instruction values.

In addition to the above example, the predetermined relationship means that the correction coefficient A is added to the average value E of the value obtained by rounding down the value less than the significant digits of each sensor, rounding up or rounding off the value, and the indicated value. An example in which the values multiplied by are equalized is also included. Further, an example is also included in which the value obtained by using the integrated value of each sensor and the value obtained by multiplying the integrated value of the indicated value by the correction coefficient A are made equal. When the average value is used, the minimum error of the sensor may be taken into consideration, and the number of times of measurement may be increased until the value of the average value becomes a predetermined value or more.

Hereinafter, the computer program according to the embodiment of the present invention will be described.
In the information processing apparatus 100 according to the present embodiment, the CPU 82 of the computer 80 executes various processing operations corresponding to computer programs, so that the various units described above are realized as various functions.

The computer program according to the present embodiment includes a procedure for obtaining a plurality of measurement values from the first sensor S1 and the second sensor S2, and a plurality of the first sensor S1 and the second sensor S2 in a computer for realizing the information processing apparatus 100. Procedure for acquiring a plurality of instruction values when the measurement values are acquired, average values G1 and G2 of a plurality of instantaneous power values of the first sensor S1 and the second sensor S2, and a plurality of instruction values corresponding to the plurality of measurement values Procedure for calculating the instantaneous power value of x, the average value E of the instantaneous values, or the integrated value of the instantaneous values, the calculated average value G2 of the second sensor S2, the average value G1 of the first sensor S1, and the indicated value x The procedure for calculating the correction coefficient A is executed so that the power instantaneous value, the average value E of the instantaneous values, or the integrated value of the instantaneous values satisfies the predetermined relationship.

The recording medium for recording the computer program 90 includes a medium that can be used by the non-transitory tangible computer 80, and the program code readable by the computer 80 is embedded in the medium. When the computer program 90 is executed on the computer 80, it causes the computer 80 to execute the following information processing method for realizing the information processing apparatus 100.

An information processing method of the information processing apparatus 100 of the present embodiment configured as above will be described below.
FIG. 12 is a flowchart showing an example of the operation of the information processing device 100 of this embodiment.
The information processing method according to the embodiment of the present invention is an information processing method of the information processing apparatus 100, and is an information processing method executed by the computer 80 that realizes the information processing apparatus 100.
In the information processing method of the present embodiment, the information processing apparatus 100 acquires a plurality of measurement values from the first sensor S1 and the second sensor S2 (step S303), and a plurality of measurement values of the first sensor S1 and the second sensor S2. A plurality of instruction values at the time of acquiring (step S307), average values G1 and G2 of a plurality of power instantaneous values of the first sensor S1 and the second sensor S2, and a plurality of instructions corresponding to the plurality of measured values. The power instantaneous value of the value x, the average value E of the instantaneous values, or the integrated value of the instantaneous values is calculated (step S313), and the calculated average value G2 of the second sensor S2 and average value G1 of the first sensor S1 are calculated. Then, the correction coefficient A is calculated so that the power instantaneous value of the instruction value x, the average value E of the instantaneous values, or the integrated value of the instantaneous values satisfies a predetermined relationship (step S317).

The details will be described below.
This flowchart is started when the information processing apparatus 100 is activated, and then repeatedly executed, for example, every predetermined period (30 minutes or the like). Here, an example in which the correction coefficient is calculated using the average value of a plurality of power instantaneous values will be described.
First, the measurement value acquisition unit 102 sets the counter i to 1 (step S301). This counter i indicates the effective number of data for calculating the average value of the measured values of each sensor, and is incremented until it reaches a predetermined number n (for example, 10) necessary for calculating the average value. (Here, i and n are natural numbers of 1 or more.)

The number of valid data n may be set according to each sensor, surrounding environment (temperature), power consumption, and the like. The number of data n may be set in advance by a program, or may be configured so that the setting can be changed or the program can be updated in accordance with a user operation or an instruction from the server 5 of the rechargeable battery.

The measurement value acquisition unit 102 acquires the electric power instantaneous value from the first sensor S1 and the second sensor S2 (step S303). It is determined whether or not the acquired instantaneous power value is a valid measured value (step S305). For example, it is determined whether the measured value is not 0, and whether or not the difference between the measured value and the instruction value is less than the predetermined ratio, and if all the conditions are satisfied, the process may proceed to step S307. If even one condition is not satisfied, the process returns to step S303. Further, in the determination that the measured value is not 0, it may be determined that the value smaller than the number of significant digits of the measured value is 0 in consideration of the error of the measured value.

When the measured value is valid (YES in step S305), the measured value is stored in the measured value storage unit 130 of the storage device 110 in FIG. 13A in association with the time information. Then, the instruction value acquisition unit 104 acquires the instruction value x and stores it in the measured value storage unit 130 of FIG. 13A in association with the corresponding measured value (step S307). Then, the counter i is incremented (step S309), and it is determined whether the number of data exceeds a predetermined number n (step S311).

As shown in FIG. 13A, when the storage battery 40 is charged, the instruction value x has a positive value, and when the storage battery 40 is discharged, the instruction value x has a negative value.

When it is determined in step S305 that the measured value is not valid (NO in step S305), the process returns to step S303, and the measured value acquisition unit 102 acquires the measured value again.

When the counter i is n or less (NO in step S311) until the number of data (counter i) exceeds the predetermined number n (NO in step S311), the process returns to step S303, the measured value and the instruction value are collected, and the measured value storage unit 130 stores them. Remember.

When the number of data (counter i) exceeds the predetermined number n (YES in step S311), the calculation unit 106 calculates average values G1 and G2 of a plurality of power instantaneous values, and correlates them with the time information as shown in FIG. ) Is stored in the average value storage unit 132 of the storage device 110 (step S313). Further, the calculation unit 106 calculates the average value E of the plurality of instruction values x corresponding to the instantaneous power value, and associates the average value E of the instruction values with the time information and the average values G1 and G2 of the instantaneous power values. The data is stored in the storage unit 132 (step S315).

As shown in FIG. 13B, when the storage battery 40 is charged, the average value of the instruction value x becomes a positive value, and when the storage battery 40 is discharged, the average value of the instruction value x becomes a negative value.

The calculation unit 106 refers to the average value storage unit 132 and subtracts the average value G1 of the instantaneous electric power values of the first sensor S1 from the average value G2 of the instantaneous electric power values of the second sensor S2 by using Expression (6). The correction coefficient A is calculated so that the result is the average value E of the instruction values x (step S317). The calculated correction coefficient A is stored in the correction coefficient storage unit 126 similar to the above embodiment.

Then, the calculation unit 106 multiplies the calculated correction coefficient A by the instruction value x to correct the instruction value x, and transmits the corrected instruction value x to the PCS 42 (step S319). Then, the process returns to step S301, and this process is repeated every predetermined period (for example, every 30 minutes).

Although not shown, the PCS 42 receives the instruction value x from the control device 50 and controls the electric power input/output to/from the power line 20 using the received instruction value x. As a result, the error of the internal sensor S0 is calibrated, and the electric power that matches the indicated value x is input to and output from the electric power line 20.

Further, the present embodiment may have a configuration in which the error between the first sensor S1 and the second sensor S2 is also corrected.
FIG. 14 is a functional block diagram logically showing the configuration of the information processing device 100 according to the embodiment of the present invention.

In the present embodiment, the power adjustment system 1 further includes a first smart meter M1 that measures the power supplied from the power system to the power line.
Then, the control unit 108 controls input/output of electric power to/from the electric power line 20.

The measurement value acquisition unit 102 acquires the measurement values from the first smart meter M1, the first sensor S1, and the second sensor S2, respectively, when the control unit 108 stops the input/output of power to/from the power line 22.

The measurement value that the measurement value acquisition unit 102 acquires from the first smart meter M1 is an instantaneous power value or an integrated power amount.

For example, when the measured value is an instantaneous power value, a plurality of measured values obtained by the measured value acquisition unit 102 from the first smart meter M1, the first sensor S1, and the first sensor S1 are associated with the time information and displayed. 15(a) is stored in the instantaneous power value storage unit 134 of the storage device 110.

Then, the calculation unit 106 calculates average values G3, G1, and G2 of a plurality of electric power instantaneous values for each of the first smart meter M1, the first sensor S1, and the second sensor S2, and stores them in a storage unit (not shown). Then, the calculating unit 106 determines that the average values G1 and G2 of the first sensor S1 and the second sensor S2 are the average values of the corresponding first smart meter M1 as shown in the following equations (7) and (8). The first sensor correction coefficient B1 and the second sensor correction coefficient B2 for correcting the average values G1 and G2 of the first sensor S1 and the second sensor S2 are calculated so as to be G3, respectively.
G3=B1*G1... Formula (7)
G3=B2·G2... Formula (8)

The calculated correction coefficients B1 and B2 of each sensor are stored in a storage unit (not shown).

When the measured value is the integrated electric energy, the measured value (integrated electric energy H3) acquired by the measured value acquisition unit 102 from the first smart meter M1 every predetermined period is associated with the time information and the storage device of FIG. It is stored in the integrated electric energy storage unit 136 of 110.

Furthermore, the measurement value acquisition unit 102 stores a plurality of measurement values (power instantaneous values) acquired from the first sensor S1 and the second sensor S2 within a predetermined period in the power instantaneous value storage unit 134 in association with time information. It The calculation unit 106 refers to the electric power instantaneous value storage unit 134 and integrates the measured values (power instantaneous values) of the first sensor S1 and the second sensor S2 for a predetermined period (or integration time), and the integrated electric energy of each sensor. H1 and H2 are calculated and stored in the integrated electric energy storage unit 136 in association with the corresponding time information and the integrated electric energy H3 of the first smart meter M1.

Then, the calculating unit 106 calculates the integrated electric energy H1 and H2 of the first sensor S1 and the second sensor S2 by the corresponding first smart meter M1 as shown in the following expressions (9) and (10). The correction coefficient B1 for the first sensor and the correction coefficient B2 for the second sensor are respectively calculated to correct the integrated electric energy H1, H2 of the first sensor S1 and the second sensor S2 so that the electric energy H3 is obtained.
H3=B1·H1... Formula (9)
H3=B2·H2... Formula (10)

The calculated correction coefficients B1 and B2 of each sensor are stored in a storage unit (not shown).
The above equations (7) to (10) show an example in which the relationship between the value of each sensor and the value obtained by multiplying the measurement value of the first smart meter M1 by the correction coefficient is equal, but the present invention is not limited to this. Not done. The calculation unit 106 may obtain a correction coefficient that satisfies a predetermined relationship between the value of each sensor and the value obtained by multiplying the measurement value of the first smart meter M1 by the correction coefficient.

In addition to the above example, the predetermined relationship means that the value of each sensor is rounded down to the nearest significant digit, rounded up or rounded off, and less than the significant digit of the measured value of the first smart meter M1 is truncated. It also includes an example in which the values obtained by multiplying the corrected values by the respective correction coefficients are made equal. Further, an example is also included in which the value obtained by using the integrated value of each sensor and the value obtained by multiplying the integrated value of the indicated value by the correction coefficient A are made equal. When the average value is used, the minimum error of the sensor may be taken into consideration, and the number of times of measurement may be increased until the value of the average value becomes a predetermined value or more.

Timing for collecting measured values (instantaneous power value or integrated power amount) from the second smart meter M2, the first sensor S1 and the second sensor S2 for calculating the correction coefficient using the measured values, and the instantaneous power from the measured values The timing and method for calculating the average value or integrated value of the values are as described above, and thus detailed description will be omitted.

When the measured value is the instantaneous power value, the integrated power amount acquired by the measured value acquisition unit 102 from the first smart meter M1 every predetermined period is associated with the time information, and the integrated power of the storage device 110 in FIG. It is stored in the amount storage unit 136. Further, the measurement value acquisition unit 102 integrates a plurality of measurement values acquired from the first sensor S1 and the second sensor S2 for a predetermined period, and stores it in the integrated electric energy storage unit 136 of the storage device 110 of FIG. To be done.

In FIG. 15A and FIG. 15B, the information of the first smart meter M1, the first sensor S1 and the second sensor S2 is associated and held, but the information is not limited to this. Information may be held for each sensor.

Then, using the calculated correction coefficients B1 and B2, the measurement value acquisition unit 102 corrects the measurement values of the first sensor S1 and the second sensor S2, respectively. Then, the calculation unit 106 calculates the above-described correction coefficient A using the corrected measurement values of the first sensor S1 and the second sensor S2.

FIG. 16 is a flowchart showing an example of the operation of the information processing apparatus 100 of this embodiment for realizing the calibration of the first sensor S1 and the second sensor S2.
The information processing method according to the embodiment of the present invention is an information processing method of the information processing apparatus 100, and is an information processing method executed by the computer 80 that realizes the information processing apparatus 100.
According to the information processing method of the present embodiment, when the information processing apparatus 100 stops the input/output of electric power to/from the electric power line 22 (step S331), the first smart meter M1, the first sensor S1, and the second sensor S2 are operated. The measured values are respectively acquired (step S333), and the measured values of the first sensor S1 and the second sensor S2 correspond to the measured values of the first smart meter M1, the first sensor S1, and the second sensor S2. The first sensor correction coefficient B1 and the second sensor correction coefficient B2 for correcting the measurement values of the first sensor S1 and the second sensor S2 are calculated so as to be the measurement values of the 1 smart meter M1 (step S337). ), the measurement values of the first sensor S1 and the second sensor S2 are respectively corrected by using the correction coefficient B1 for the first sensor and the correction coefficient B2 for the second sensor (step S339), and the first sensor S1 and the second sensor are corrected. The correction coefficient A is calculated using the corrected measurement value of S2 (step S303 to step S317 of FIG. 12).

The details will be described below.
This flowchart is performed before the above-described processing of FIG. 12 when the calibration of the first sensor S1 and the second sensor S2 is required. That is, the processing is started when the information processing apparatus 100 is activated, and then repeatedly executed, for example, every predetermined period (30 minutes or the like).

First, the control unit 108 stops the input/output of electric power to/from the electric power line 22 (step S331). Specifically, the control unit 108 transmits the instruction value x in which 0 is set to the PCS 42.

Then, the measurement value acquisition unit 102 respectively acquires measurement values from the first smart meter M1, the first sensor S1, and the second sensor S2 (step S333). Each acquired measurement value is stored in the instantaneous power value storage unit 134 or the integrated power amount storage unit 136 of the storage device 110 of FIG. 15A in association with the time information.

The measured value is an instantaneous electric power value or an integrated electric energy. The processing for each measurement value is as described above, and detailed description will be omitted here. Then, control unit 108 cancels the stop of the input and output of electric power to electric power line 22 (step S335).

Then, the calculation unit 106 determines that the value of the first sensor S1, the value of the second sensor S2, and the value of the first smart meter M1 are expressed by the formula (7) and the formula (8) or the formula (9) and the formula (10). ), the first correction coefficient B1 for the first sensor S1 and the second correction coefficient B2 for the second sensor S2 are calculated so as to satisfy the predetermined relationship (step S337).

Then, using the calculated correction coefficients B1 and B2, the measurement values of the first sensor S1 and the second sensor S2 acquired by the measurement value acquisition unit 102 are respectively corrected (step S339).

The process of step S339 may be executed after the measurement values are acquired in step S303 of FIG.

As described above, the first sensor S1 and the second sensor S2 can be calibrated before calculating the correction coefficient A for calibrating the internal sensor S0.

The correction coefficient A is calculated by 106.
Further, in the present embodiment, the correction coefficient is calculated by the calculation unit 106 based on the measurement values obtained from the first sensor S1 and the second sensor S2 instead of the second smart meter M2.

In the present embodiment, since the first sensor S1 and the second sensor S2 are electrically connected to the PCS 42, unlike the case of wireless communication of the second smart meter M2, there are no missing measurement values due to communication errors or the like. In addition, this embodiment can realize the power adjustment system 1 at a lower cost than the second smart meter M2.

Further, in the present embodiment, since the calibration of the first sensor S1 and the second sensor S2 can be periodically executed, the accuracy of power control can be maintained.

As described above, according to the information processing apparatus 100 of the present embodiment, it is possible to achieve the same effect as that of the above-described embodiment, and further, it is possible to efficiently realize highly accurate power control in the consumer.

(Fourth Embodiment)
Next, a fourth embodiment of the present invention will be described below.
FIG. 17 is a diagram conceptually showing the system configuration of the power adjustment system 1 according to the embodiment of the present invention.
The power adjustment system 1 of the present embodiment differs from the above-described embodiment in that it has a second sensor S2 as a measurement value acquisition means and does not use the first sensor S1.

The second sensor S2 measures the current value of the power flowing through the second power line 20b.
The PCS 42 is electrically connected to the second sensor S2 and acquires a current value from the second sensor S2.

The information processing apparatus 100 according to the present embodiment has the same configuration as that of the above-described embodiment, and will be described with reference to FIG.
The information processing apparatus 100 according to the present embodiment is different from the above-described embodiment in that the calculation unit based on the measurement values acquired by the measurement value acquisition unit 102 as the measurement value acquisition unit from the first smart meter M1 and the second sensor S2. The difference is that 106 has a configuration for calculating a correction coefficient.

In the information processing apparatus 100 according to the present embodiment, the measurement value acquisition unit 102 uses the first smart meter M1 that measures the power supplied to the power line from the power system 10 and the second sensor S2 to measure the value (power instantaneous Value) is acquired at least one each.

Each power instantaneous value is acquired by the measurement value acquisition unit 102 at successive timings (for example, 10 times every few seconds in the first 1 minute of 30 minutes) within a predetermined time of a predetermined period, as in the above embodiment. To be done.
In this way, the measured value acquisition unit 102 acquires at least one electric power instantaneous value as a measured value from each of the first smart meter M1 and the second sensor S2.

Furthermore, the instruction value acquisition unit 104 acquires at least one instruction value when at least one measurement value of the first smart meter M1 and the second sensor S2 is acquired. It is desirable that the instruction value acquisition unit 104 acquires the instruction value at the same timing as the measurement value acquisition unit 102 acquires the measurement value. However, it does not always have to be the same.

The calculation unit 106 calculates the correction coefficient using at least one electric power instantaneous value for each of the first smart meter M1 and the second sensor S2 and the instruction value corresponding to the measured value.
In the present embodiment, an example will be described in which the correction coefficient is calculated using the average value of the plurality of instruction values corresponding to the average value of the plurality of power instantaneous values. Further, the correction coefficient may be calculated using one instruction value corresponding to one electric power instantaneous value, or using the integrated value of a plurality of indicated values corresponding to the integrated value of a plurality of instantaneous electric power values. The correction coefficient may be calculated.

The calculating unit 106 calculates the average values G3 and G2 of the plurality of instantaneous power values of the first smart meter M1 and the second sensor S2, and the average value E of the plurality of instruction values x corresponding to the plurality of measured values, respectively.
For example, in charge/discharge control of the storage battery 40, the instruction value x has a negative value during discharge control of the storage battery 40, and the instruction value x has a positive value during charge control of the storage battery 40.

In the power adjustment system 1, if there is no reverse power flow to the power system 10, the measurement value (power instantaneous value) of the second sensor S2 is measured on the forward power flow side of the first smart meter M1 during discharge control of the storage battery 40. It becomes equal to the sum of the absolute value of the value (power instantaneous value) and the power instantaneous value (negative) measured by the internal sensor S0. During charge control of the storage battery 40, the forward power flow side measured value (power instantaneous value) of the first smart meter M1 is the power measured by the second sensor S2 (power instantaneous value) and the internal sensor S0. Equal to the sum of the values (positive).

Further, when the instantaneous electric power value input/output by the measurement of the internal sensor S0 is different from the indicated value x due to the error of the internal sensor S0, the indicated value x is multiplied by the correction coefficient A to be measured by the internal sensor S0. The instantaneous power value (power input to and output from the power line 20) can be made equal to the indicated value x.

From these, the calculation unit 106 calculates the correction coefficient A as shown in the following formula (11) or formula (12) according to the discharge and charge of the storage battery 40.
G3+A·|E|=G2... Formula (11)
G3=A*E+G2... Formula (12)

The above equations (11) and (12) show an example in which the relationship between the value of G2 and G3 and the value obtained by multiplying the average value E of the instruction values by the correction coefficient A is equal. Not limited. The calculation unit 106 may obtain a correction coefficient satisfying a predetermined relationship between the values of G2 and G3 and the value obtained by multiplying the average value E of the instruction values by the correction coefficient A.

In addition to the above example, the predetermined relationship means that the correction coefficient A is added to the average value E of the value obtained by rounding down the value less than the significant digits of each sensor, rounding up or rounding off the value, and the indicated value. An example in which the values multiplied by are equalized is also included.

Further, as a configuration for realizing the calibration of the second sensor S2 used to calculate the correction coefficient A, the calculation unit 106 causes the first smart meter M1 to operate when the storage battery 40 is not charged or discharged. , And the average values G3 and G2 (or integrated electric energy H3 and H2) of a plurality of electric power instantaneous values for each second sensor S2 are calculated and stored in a storage unit (not shown). Then, the calculation unit 106 calculates the average value G2 (or the integrated electric energy H2) of the second sensor S2 of the corresponding first smart meter M1 as shown in the above-described expression (8) (or expression (10)). The correction coefficient B2 for the second sensor that corrects the average value G2 (integrated power amount H3) of the second sensor S2 is calculated so that the average value G3 (or the integrated power amount H3) is obtained.

As the value used for calculating the correction coefficient, one power instantaneous value or an integrated value of a plurality of power instantaneous values may be used in addition to the average value of the plurality of power instantaneous values.

The calculated correction coefficient B2 of each sensor is stored in a storage unit (not shown).

Then, the measured value acquisition unit 102 corrects the measured value of the second sensor S2 by using each calculated correction coefficient B2. Then, the calculation unit 106 calculates the above-described correction coefficient A using the corrected measurement value of the second sensor S2.

Hereinafter, the computer program according to the embodiment of the present invention will be described.
In the information processing apparatus 100 according to the present embodiment, the CPU 82 of the computer 80 executes various processing operations corresponding to computer programs, so that the various units described above are realized as various functions.

The computer program of the present embodiment uses a computer for realizing the information processing apparatus 100 to acquire a plurality of measurement values from each of the first smart meter M1 and the second sensor S2, the first smart meter M1 and the first smart meter M1. 2 Procedure for acquiring a plurality of indication values when a plurality of measurement values of the sensor S2 are acquired, average values G3 and G2 of a plurality of instantaneous power values of the first smart meter M1 and the second sensor S2, and a plurality of measurement values The procedure for calculating the average value E of the plurality of instruction values x corresponding to, the calculated average value G2 of the second sensor S2, the average value G3 of the first smart meter M1, and the average value E of the instruction values x. Is to execute the procedure for calculating the correction coefficient A so as to satisfy the equation (11) or the equation (12).

The recording medium for recording the computer program 90 includes a medium that can be used by the non-transitory tangible computer 80, and the program code readable by the computer 80 is embedded in the medium. When the computer program 90 is executed on the computer 80, it causes the computer 80 to execute the following information processing method for realizing the information processing apparatus 100.

An information processing method of the information processing apparatus 100 of the present embodiment configured as above will be described below.
18 and 19 are flowcharts showing an example of the operation of the information processing apparatus 100 of this embodiment. FIG. 18 is a flowchart showing an example of the operation of the information processing apparatus 100 for realizing the calibration of the first sensor S1 and the second sensor S2. FIG. 19 is a flowchart showing an example of the operation of the information processing device 100 for realizing the calibration of the internal sensor S0.

The information processing method according to the embodiment of the present invention is an information processing method of the information processing apparatus 100, and is an information processing method executed by the computer 80 that realizes the information processing apparatus 100.
In the information processing method according to the present embodiment, the information processing apparatus 100 acquires a plurality of measurement values from the first smart meter M1 and the second sensor S2 (step S413), and then the first smart meter M1 and the second sensor. A plurality of indication values when a plurality of measurement values of S2 are obtained are obtained (step S417), and average values G3 and G2 of a plurality of electric power instantaneous values of the first smart meter M1 and the second sensor S2 and a plurality of measurements The average value E of the plurality of instruction values x corresponding to the respective values is calculated (step S423, step S425), the calculated average value G2 of the second sensor S2, the average value G3 of the first smart meter M1, and the instruction. The correction coefficient A is calculated so that the average value E of the values x satisfies the expression (11) or the expression (12) (step S427).

The details will be described below.
This flowchart is performed before the process of FIG. 19 described later when the calibration of the first sensor S1 and the second sensor S2 is required. The processing is started when the information processing apparatus 100 is activated, and then repeatedly executed, for example, every predetermined period (30 minutes or the like).

First, the control unit 108 stops input/output of electric power to/from the electric power line 20 (step S401). Specifically, the control unit 108 transmits the instruction value x in which 0 is set to the PCS 42.

Then, the measurement value acquisition unit 102 acquires the measurement values from the first smart meter M1 and the second sensor S2 (step S403). Each acquired measurement value is stored in the instantaneous power value storage unit 134 or the integrated power amount storage unit 136 of the storage device 110 in association with the time information.

The measured value is an instantaneous electric power value or an integrated electric energy. The processing for each measurement value is as described above, and detailed description will be omitted here. Then, control unit 108 cancels the stop of the input and output of electric power to electric power line 20 (step S405).

Then, the calculation unit 106 uses the value for the second sensor S2 so that the value of the second sensor S2 and the value of the first smart meter M1 satisfy a predetermined relationship as shown in Expression (8) or Expression (10). The second correction coefficient B2 is calculated (step S407).

The calculated correction coefficient B2 is stored in a storage unit (not shown).
Then, the process proceeds to the flowchart of FIG.

First, the measurement value acquisition unit 102 sets the counter i to 1 (step S411). This counter i indicates the effective number of data for calculating the average value of the measured values of the respective sensors, and is incremented until it reaches a predetermined number n (for example, 10) necessary for calculating the average value. (Here, i and n are natural numbers of 1 or more.)

The number of valid data n may be set according to each sensor, surrounding environment (temperature), power consumption, and the like. The number of data n may be set in advance by a program, or may be configured so that the setting can be changed or the program can be updated in accordance with a user operation or an instruction from the server 5 of the rechargeable battery.

The measurement value acquisition unit 102 acquires measurement values (power instantaneous values) from the first smart meter M1 and the second sensor S2. Furthermore, the measurement value acquisition unit 102 performs correction by multiplying the measurement value of the second sensor S2 by the correction coefficient B2 calculated in the processing procedure of FIG. 18 (step S413). Then, it is determined whether the corrected value or the measurement value of the first smart meter M1 is valid (step S415). For example, it is determined that the value is not 0, and whether the difference between the value and the indicated value is less than the predetermined ratio. If all the conditions are satisfied, the process may proceed to step S307. If even one condition is not satisfied, the process returns to step S413. Further, in the determination that the measured value is not 0, it may be determined that the value smaller than the number of significant digits of the measured value is 0 in consideration of the error of the measured value.

When the value is valid (YES in step S415), each value is stored in the measured value storage unit 130 of the storage device 110 of FIG. 13A in association with the time information. Then, the instruction value acquisition unit 104 acquires the instruction value x and stores it in the measured value storage unit 130 of FIG. 13A in association with the corresponding measured value (step S417). Then, the counter i is incremented (step S419), and it is determined whether the number of data exceeds a predetermined number n (step S421).

As shown in FIG. 13A, when the storage battery 40 is charged, the instruction value x has a positive value, and when the storage battery 40 is discharged, the instruction value x has a negative value.

When it is determined in step S415 that the value is not valid (NO in step S415), the process returns to step S413, and the measurement value acquisition unit 102 acquires the measurement value again.

Then, until the number of data (counter i) exceeds the predetermined number n, if the counter i is equal to or less than n (NO in step S421), the process returns to step S413, collects the measured value and the instruction value, and stores them in the measured value storage unit 130. Remember.

When the number of data (counter i) exceeds the predetermined number n (YES in step S421), the calculation unit 106 calculates the average value G2 of a plurality of power instantaneous values and associates the time information with the time information of FIG. 13(b). It is stored in the average value storage unit 132 of the storage device 110 (step S423). Further, the calculation unit 106 calculates an average value E of the plurality of instruction values x corresponding to the instantaneous power value, associates the average value E of the instruction values with the time information and the average value G2 of the instantaneous power values, and stores the average value E in the average value storage unit. It is stored in 132 (step S425).

As shown in FIG. 13B, when the storage battery 40 is charged, the average value of the instruction value x becomes a positive value, and when the storage battery 40 is discharged, the average value of the instruction value x becomes a negative value.

The calculation unit 106 refers to the average value storage unit 132 and uses Expression (11) to calculate the calculated average value G2 of the second sensor S2, the average value G3 of the first smart meter M1, and the instruction value x. The correction coefficient A is calculated so that the average value E satisfies Expression (11) or Expression (12) (step S427). The calculated correction coefficient A is stored in the correction coefficient storage unit 126 similar to the above embodiment.

Then, the calculation unit 106 multiplies the calculated correction coefficient A by the calculated instruction value x to correct the instruction value x, and transmits the corrected instruction value x to the PCS 42 (step S429).
After this process is completed, the process returns to step S401 in FIG. 18, and a series of processes is repeated every predetermined period (for example, every 30 minutes).

Although not shown, the PCS 42 receives the instruction value x from the control device 50 and controls the electric power input/output to/from the power line 20 using the received instruction value x. As a result, the error of the internal sensor S0 is calibrated, and the electric power that matches the indicated value x is input to and output from the electric power line 20.

As described above, in the information processing device 100 of the power adjustment system 1, the calculation unit so that the measurement value acquired by the measurement value acquisition unit 102 becomes the corresponding instruction value acquired by the instruction value acquisition unit 104. The correction coefficient A is calculated by 106.
Further, in the present embodiment, the correction coefficient is calculated by the calculation unit 106 based on the measurement values obtained from the first smart meter M1 and the second sensor S2 instead of the second smart meter M2. At this time, the calibration of the second sensor S2 can also be performed by the first smart meter M1.

Since only one current sensor is required as compared with the above embodiment, the use of one input port of the PCS 42 is unnecessary. The vacant I/O port (not shown) of the PCS 42 can be used for other functions. Further, since the first smart meter M1 that is originally provided by the electric power company installed in the customer's home can be used, the installation cost can be reduced.

As described above, according to the information processing apparatus 100 of the present embodiment, it is possible to achieve the same effects as those of the above-described embodiment, and further, it is possible to realize highly accurate power control in a consumer with a simple configuration.

(Fifth Embodiment)
Next, a fifth embodiment of the present invention will be described below.
FIG. 20 is a diagram conceptually showing the system configuration of the power adjustment system 1 according to the embodiment of the present invention.
The power adjustment system 1 of the present embodiment is different from the above-described embodiment in that the temperature of the sensor is measured, the calculated correction coefficient is stored for each temperature, and a database is provided.
In the present embodiment, the power adjustment system 1 of the embodiment of FIG. 11 is provided with a temperature-dependent correction coefficient database (denoted as “DB” in the figure) 52, but the power adjustment system 1 of the embodiment of FIG. Can also be combined with. Furthermore, the configuration for constructing the temperature-dependent correction coefficient table 156 of the correction coefficient A may be combined with the power adjustment system 1 of the other embodiments within a range that does not conflict.

For example, the second temperature-based correction coefficient table 156 may be combined with the power adjustment system 1 of the embodiment of FIG. In this configuration, since the second smart meter M2 is used without using the first sensor S1 and the second sensor S2, the calculation process of the correction coefficients B1 and B2 becomes unnecessary. That is, the first temperature-dependent correction coefficient table 154 is unnecessary.

FIG. 21 is a functional block diagram logically showing the configuration of the information processing device 100 according to the embodiment of the present invention.
The information processing apparatus 100 of this embodiment has the same configuration as the information processing apparatus 100 of FIG. 14, and further includes a temperature acquisition unit 152.

The temperature acquisition unit 152 acquires the measured temperature around the sensor for each of at least one of the first sensor S1, the second sensor S2, and the internal sensor S0.
Further, the information processing apparatus 100 is connected to the temperature-dependent correction coefficient database 52 so as to be accessible. The temperature-dependent correction coefficient database 52 may be included inside the information processing device 100 or may be included in an external device.

FIG. 22 is a diagram showing an example of the data structure of each table of the temperature-dependent correction coefficient database 52 of the present embodiment.
The temperature-dependent correction coefficient database 52 has a first temperature-based correction coefficient table 154 shown in FIG. 22A and a second temperature-based correction coefficient table 156 shown in FIG. 22B.
The first temperature-dependent correction coefficient table 154 stores the first sensor S1 correction coefficient B1 or the second sensor S2 correction coefficient B2 calculated by the calculation unit 106 for each temperature.
The measurement value acquisition unit 102 acquires the correction coefficients B1 and B2 corresponding to the temperature around each sensor acquired by the temperature acquisition unit 152 from the first temperature-dependent correction coefficient table 154, and the acquired correction coefficient B1 for each sensor. , B2 are used to correct the measurement value of each sensor. At this time, the processing procedure shown in the flowchart of FIG. 16 or FIG. 18 (hereinafter, referred to as sensor correction coefficient calculation processing) described in the above embodiment is not executed.

The calculation unit 106 shifts the correction coefficients when the correction coefficients B1 and B2 of each sensor corresponding to the temperature are not stored in the first temperature-based correction coefficient table 154, or when a predetermined time has elapsed from the correction coefficient update. When it is considered that the error occurs (for example, the predetermined time is one month, etc.), the sensor correction coefficient calculation process is executed to calculate the correction coefficients B1 and B2.
Then, the calculated correction coefficients B1 and B2 are stored in the first temperature-dependent correction coefficient table 154 in association with the temperature.

Further, the temperature acquisition unit 152 may acquire the temperature around the internal sensor S0.
In the second temperature-dependent correction coefficient table 156 of FIG. 15B, the correction coefficient A calculated by the calculation unit 106 is stored for each temperature.
The control unit 108 corrects the instruction value x using the acquired correction coefficient A and transmits it to the PCS 42 (step S319 in FIG. 12 or step S429 in FIG. 19). At this time, the processing procedure (excluding step S319 and step S429) shown in the flowchart of FIG. 12 or FIG. 19 described in the above embodiment (hereinafter, referred to as correction coefficient calculation processing) is not executed.

The calculation unit 106 determines that the correction coefficient A corresponding to the temperature is not stored in the second temperature-dependent correction coefficient table 156, or that the correction coefficient is deviated after a predetermined time has elapsed since the correction coefficient was updated. If it can be considered (for example, the predetermined time is one month, etc.), the correction coefficient calculation process is executed to calculate the correction coefficient A. Then, control unit 108 corrects instruction value x using calculated correction coefficient A, and transmits it to PCS 42 (step S319 in FIG. 12 or step S429 in FIG. 19).

Then, the calculated correction coefficient A is stored in the second temperature-based correction coefficient table 156 in association with the temperature.

In the first temperature-dependent correction coefficient table 154 of FIG. 22A and the second temperature-based correction coefficient table 156 of FIG. 22B, the temperature (° C.) is in units of 1° C., but is not limited to this. Alternatively, the temperature may be a unit of 1° C. or higher, or a unit finer than 1° C. Further, the correction coefficient may be held for each temperature range in which the difference between the correction coefficients for each temperature is within a predetermined value, and the width of the range may differ depending on the temperature. If the temperature itself corresponding to the current temperature does not exist in the temperature-dependent correction coefficient table, it is calculated by proportional division from the correction coefficients of the temperatures before and after that.

Hereinafter, the computer program according to the embodiment of the present invention will be described.
In the information processing apparatus 100 according to the present embodiment, the CPU 82 of the computer 80 executes various processing operations corresponding to computer programs, so that the various units described above are realized as various functions.

The computer program according to the present embodiment causes a computer for realizing the information processing apparatus 100 to acquire a measured ambient temperature for each of at least one of the first sensor S1 and the second sensor S2. A procedure for acquiring a correction coefficient corresponding to the acquired ambient temperature of each sensor from the first temperature-dependent correction coefficient table 154, a procedure for correcting the measurement value of each sensor using the acquired correction coefficient for each sensor, and a first When the correction coefficient for each sensor corresponding to the temperature is not stored in the temperature-dependent correction coefficient table 154, or when it is considered that a predetermined time has elapsed since the correction coefficient was updated and the correction coefficient has deviated, the correction coefficient is corrected. The procedure of calculating the coefficient, the procedure of storing the calculated correction coefficient B1 for the first sensor S1 or the correction coefficient B2 for the second sensor S2 in the first temperature-dependent correction coefficient table 154 for each temperature, are executed. is described.

The recording medium for recording the computer program 90 includes a medium that can be used by the non-transitory tangible computer 80, and the program code readable by the computer 80 is embedded in the medium. When the computer program 90 is executed on the computer 80, it causes the computer 80 to execute the following information processing method for realizing the information processing apparatus 100.

An information processing method of the information processing apparatus 100 of the present embodiment configured as above will be described below.
FIG. 23 is a flowchart showing an example of the operation of the information processing device 100 of this embodiment.
The information processing method according to the embodiment of the present invention is an information processing method of the information processing apparatus 100, and is an information processing method executed by the computer 80 that realizes the information processing apparatus 100.
In the information processing method according to the present embodiment, the information processing apparatus 100 acquires the measured ambient temperature for at least one of the first sensor S1 and the second sensor S2 (step S501), and acquires the acquired ambient temperature. The correction coefficient corresponding to the ambient temperature of each sensor is acquired from the first temperature-dependent correction coefficient table 154 (YES in step S505, step S507), and the measured value of each sensor is obtained using the acquired correction coefficient for each sensor. When the correction coefficient is corrected (step S<b>509 ), and the correction coefficient of each sensor corresponding to the temperature is not stored in the first temperature-dependent correction coefficient table 154, or when the correction coefficient is updated and a predetermined time has elapsed, the correction coefficient shifts. If it is considered (NO in step S505), the correction coefficient is calculated (step S511), and the calculated correction coefficient B1 for the first sensor S1 or the correction coefficient B2 for the second sensor S2 is calculated for each temperature. Each is stored in the correction coefficient table 154 for each temperature (step S513).

The details will be described below.
First, the temperature acquisition unit 152 acquires the measured ambient temperature for at least one of the first sensor S1 and the second sensor S2 (step S501).
The measurement value acquisition unit 102 refers to the first temperature-based correction coefficient table 154 (step S503), and the correction coefficient corresponding to the temperature around each sensor acquired by the temperature acquisition unit 152 is the first temperature-based correction coefficient table. It is determined whether it is in 154 (step S505).

If there is a correction coefficient corresponding to the temperature, or if it is considered that a predetermined time has elapsed since the correction coefficient was updated and the correction coefficient has shifted (YES in step S505), the measurement value acquisition unit 102 The correction coefficient B1 for the first sensor S1 and the correction coefficient B2 for the second sensor S2 corresponding to the temperature are acquired from the 1-temperature-based correction coefficient table 154 (step S507), and the acquired correction coefficient B1 for the first sensor S1 and the second correction coefficient B2 are acquired. The measurement values of the first sensor S1 and the second sensor S2 are respectively corrected using the correction coefficient B2 for the sensor S2 (step S509).

On the other hand, when there is no correction coefficient corresponding to the temperature (NO in step S505), the calculation unit 106 executes the correction coefficient calculation process (step S511). Here, the correction coefficient calculation process can be the process of the above-described embodiment described using FIG. 16 or FIG. 18 (step S331 to step S337 in FIG. 16, step S401 to step S407 in FIG. 18). ..

Then, the calculation unit 106 stores the calculated correction coefficient B1 for the first sensor S1 or the correction coefficient B2 for the second sensor S2 for each temperature in the correction coefficient table 154 for each temperature (step S513). Then, the process proceeds to step S509, and the measurement value acquisition unit 102 uses the calculated correction coefficient B1 for the first sensor S1 or the correction coefficient B2 for the second sensor S2 to calculate the measurement values of the first sensor S1 and the second sensor S2, respectively. to correct.

As described above, the information processing apparatus 100 according to the present embodiment uses the first temperature-based correction coefficient table 154 to calculate the first sensor S1 correction coefficient B1 or the second sensor S2 correction coefficient B2. It is not necessary to frequently perform every short predetermined period.

Further, during the calculation process of the correction coefficient, a period for stopping the input/output to/from the power line 20 is required in steps S331 to S335 of FIG. 16 or steps S401 to S405 of FIG. However, according to the present embodiment, when the correction coefficient of the first correction coefficient table for each temperature 154 is used, the period for stopping the input/output to/from the power line 20 is unnecessary, so that the supply/demand adjustment by the calibration process is performed. Can reduce the effect of.

Further, when the correction coefficient B1 for the first sensor S1 or the correction coefficient B2 for the second sensor S2 is calculated and stored in the first temperature-based correction coefficient table 154 in association with the temperature, the temperature-based correction coefficient database 52 is stored. Can be built.

Further, in the information processing apparatus 100 of the present embodiment, in addition to the correction coefficient B1 for the first sensor S1 or the correction coefficient B2 for the second sensor S2, the correction coefficient A for the second temperature is corrected by the same processing procedure for the correction coefficient A. By using, it becomes unnecessary to frequently perform the calculation processing of the correction coefficient A at each predetermined short period. Further, when the correction coefficient A is calculated and stored in the second temperature-specific correction coefficient table 156 in association with the temperature, the temperature-specific correction coefficient database 52 can be constructed.

In the case of the second temperature-dependent correction coefficient table 156, in step S501, the temperature acquisition unit 152 acquires the temperature around the internal sensor S0.
Further, the correction coefficient calculation process of step S511 is the process of steps S101 to S113 of FIG. 4, steps S201 to S217 of FIG. 8, steps S301 to S317 of FIG. 12, or steps S411 to S427 of FIG. Can be a procedure. That is, when the correction coefficient A corresponding to the temperature is present in the second temperature-dependent correction coefficient table 156, these processing procedures can be bypassed, which is efficient.

As described above, in the information processing apparatus 100 according to the present embodiment, the temperature of the sensor is measured by the temperature acquisition unit 152, and the correction coefficient calculated by the calculation unit 106 is the first correction coefficient table 154 for each temperature or the correction coefficient table for each temperature. 2 The correction coefficient table for each temperature 156 is stored in the database.

Then, when the internal sensor S0 is calibrated, if a correction coefficient corresponding to the current temperature already exists in the temperature-dependent correction coefficient database 52, that value can be used. It can be omitted.

As described above, according to the information processing apparatus 100 of the present embodiment, it is possible to achieve the same effect as that of the above-described embodiment, and further, it is possible to efficiently realize highly accurate power control in the consumer.

(Sixth Embodiment)
Next, a sixth embodiment of the present invention will be described below.
FIG. 24 is a diagram conceptually showing the system configuration of the power adjustment system 1 according to the embodiment of the present invention.
The power adjustment system 1 of the present embodiment is different from the above-described embodiment in that the correction coefficient is stored for each electric power indicated by the instruction value and is stored in a database.
In the present embodiment, the power adjustment system 1 of the embodiment of FIG. 1 is provided with a correction coefficient database for each power (indicated as “DB” in the figure) 54, but in the power adjustment system 1 of another embodiment. May be combined as long as there is no contradiction. Especially, it is effective to combine with the fifth embodiment.

Further, for example, it may be combined with the power adjustment system 1 of FIG. 11 or FIG. In this configuration, the input and output electric powers are set to different values by setting the instruction values to different constant values, and the correction coefficients B1 and B2 for calibration of the first sensor S1 and the second sensor S2 are calculated for each different electric power, Each correction coefficient for each power may be further stored in the power-specific correction coefficient table 164 of the power-specific correction coefficient database 54.

FIG. 25 is a functional block diagram logically showing the configuration of the information processing device 100 according to the embodiment of the present invention.
The information processing apparatus 100 according to the present embodiment has the same configuration as the information processing apparatus 100 in FIG.
Further, the information processing apparatus 100 is connected to the power-based correction coefficient database 54 so as to be accessible. The power-based correction coefficient database 54 may be included inside the information processing apparatus 100 or may be included in an external apparatus.

The database construction unit 162 associates the correction coefficient for each power and stores it in the power-specific correction coefficient table 164. The database construction unit 162 sets the instruction value to a plurality of different predetermined constant values for each predetermined setting period. The set instruction value is transmitted to the PCS 42 when the information processing device 100 is the control device 50.
In the PCS 42, the electric power input/output to/from the power line 20 is controlled according to the instruction value received from the control device 50, and the electric power input/output to/from the electric power line 20 has a plurality of different predetermined constant values for each predetermined set period. Become.
Then, the database construction unit 162 stores the plurality of correction coefficients calculated by the calculation unit 106 in the power-based correction coefficient table 164 in association with the value of the power when the power reaches a constant value.

Here, the measurement value acquisition unit 102 of the present embodiment acquires a 30-minute value (integrated electric energy accumulated at 30-minute intervals) from the second smart meter M2. The start time and the end time of the integrated time (30 minutes) in which the second smart meter M2 integrates the electric energy may be acquired from, for example, 30-minute time information. However, the time information may not be used, and for example, the predetermined setting period for continuously setting the indicated value to a constant value is set to 60 minutes, which is twice the integration time (30 minutes) of the second smart meter M2. , 60 minutes always includes the integrated time of the 30-minute value of the second smart meter M2. Therefore, in the present embodiment, the predetermined set period is set to 60 minutes, which is twice the integration time (30 minutes) of the second smart meter M2.

Further, in the above embodiment, the measurement value acquisition unit 102 acquires the cumulative integrated electric energy for each predetermined period (for example, 30 minutes). This measured value may be used, and in that case, the measured value may be acquired at each of the start time and the end time of the predetermined set period. With this method, the predetermined period can be shorter than 30 minutes (for example, 5 minutes), and the correction coefficient can be calculated at shorter time intervals.

FIG. 26 is a diagram showing an example of the data structure of the power-specific correction coefficient table 164 of the power-specific correction coefficient database 54 of the present embodiment.
The database construction unit 162 stores the correction coefficient A calculated by the calculation unit 106 for each temperature.
In the power-based correction coefficient table 164 of FIG. 26, the power (W) is in 100 W units, but the power is not limited to this, and the power may be a unit larger than 100 W or a unit smaller than 100 W. It may be. Further, the correction coefficient may be held for each power range in which the difference between the correction coefficients for each power is within a predetermined value, and the width of the range may differ depending on the power value. If there is no correction coefficient corresponding to the required power in the correction coefficient table for each power 164, the correction coefficient is calculated from the correction coefficients of the power above and below the power by proportional division.

Also in the present embodiment, the correction coefficient of the power-specific correction coefficient table 164 can be used as in the above embodiment.
That is, when the correction coefficient A corresponding to the power indicated by the instruction value is stored in the power-specific correction coefficient table 164, the control unit 108 uses the correction coefficient A acquired from the power-specific correction coefficient table 164 to indicate the instruction value. x is corrected and transmitted to the PCS 42 (step S115 in FIG. 4). At this time, step S113 of FIG. 4 (hereinafter referred to as correction coefficient calculation processing) described in the above embodiment is not executed. If the PCS 42 has the power-specific correction coefficient table 164, the PCS 42 corrects the instruction value x.

The calculation unit 106 does not store the correction coefficient A corresponding to the power indicated by the instruction value in the power-based correction coefficient table 164, or if the correction coefficient has been displaced for a predetermined time after the correction coefficient is updated. When it is considered that the correction coefficient A is present (for example, the predetermined time is one month), the correction coefficient calculation process (step S113 in FIG. 4) is executed to calculate the correction coefficient A. Then, the control unit 108 corrects the instruction value x using the calculated correction coefficient A and transmits it to the PCS 42 (step S115 in FIG. 4).

Hereinafter, the computer program according to the embodiment of the present invention will be described.
In the information processing apparatus 100 according to the present embodiment, the CPU 82 of the computer 80 executes various processing operations corresponding to computer programs, so that the various units described above are realized as various functions.

The computer program of the present embodiment causes the computer for realizing the information processing apparatus 100 to input and output electric power to and from the electric power line 20 in accordance with an instruction value set to a plurality of different predetermined constant values for each predetermined set period. Is set to a plurality of different predetermined constant values for each predetermined setting period, and the integrated electric energy for each predetermined setting period in which the input/output power becomes a plurality of different predetermined constant values is calculated from the second smart meter M2. Obtaining procedure, procedure for calculating the correction coefficient so that the integrated electric energy is the integrated instruction value obtained by accumulating the instruction value corresponding to the integrated electric energy for each predetermined setting period for each predetermined setting period, and the plurality of calculated corrections It is described that the coefficient is stored in the power-specific correction coefficient table 164 in association with a plurality of electric powers indicated by a plurality of different predetermined fixed values.

FIG. 28 is a flowchart showing an example of the procedure of a correction process using the power-specific correction coefficient table 164.

The information processing method according to the embodiment of the present invention is an information processing method of the information processing apparatus 100, and is an information processing method executed by the computer 80 that realizes the information processing apparatus 100.
As shown in FIG. 27, in the information processing method according to the present embodiment, the information processing apparatus 100 inputs/outputs to/from the power line 20 according to an instruction value set to a plurality of different predetermined constant values for each predetermined setting period. Power is set to a plurality of different predetermined constant values for each predetermined setting period (step S601), and the integrated electric energy for each predetermined setting period when the input/output power becomes a plurality of different predetermined constant values is set to the second smart value. Each is acquired from the meter M2 (step S603), and the correction coefficient is calculated so that the integrated electric energy becomes the integrated instruction value obtained by accumulating the instruction value corresponding to the integrated electric energy for each predetermined setting period for each predetermined setting period ( Step S605), storing the calculated plurality of correction coefficients in the power-specific correction coefficient table 164 in association with the plurality of powers indicated by the respective instruction values set to different predetermined constant values (step S607). including.

The database construction unit 162 of the information processing apparatus 100 according to the present embodiment performs the above-described processing repeatedly with a plurality of different powers by changing the instruction value, calculates the correction coefficient for each power, and saves the correction coefficient for each power. The coefficient database 54 is constructed.

Further, as shown in FIG. 28, in the information processing method according to the present embodiment, the information processing apparatus 100 acquires an instruction value (step S611), refers to the power-based correction coefficient table 164 (step S613), and acquires the instruction value. When the correction coefficient corresponding to the power indicated by the instruction value is in the power-specific correction coefficient table 164 (YES in step S613), the correction coefficient is acquired (step S617), and the acquired correction coefficient for each sensor is used for each sensor. The measured value is corrected (step S619), and when the correction coefficient corresponding to the power indicated by the instruction value is not stored in the power-specific correction coefficient table 164, or when the correction coefficient is updated and a predetermined time has elapsed, the correction coefficient shifts. When it is considered that the error has occurred (NO in step S615), the correction coefficient is calculated (step S621), and the calculated correction coefficient A is stored in the power-specific correction coefficient table 164 for each power (step S623). ), Including.

Further, if the correction coefficients for all the powers are stored in association with the power-specific correction coefficient table 164 by the processing procedure of FIG. 27, steps S615, S621, and S623 of FIG. 28 are unnecessary.

As described above, in the information processing apparatus 100 according to the present embodiment, the correction coefficient calculated by the calculation unit 106 is stored in the power-specific correction coefficient table 164 for each different power, and is stored in the database.

Note that the configuration of this embodiment can be combined with at least one configuration of other embodiments of the present invention in a range that does not contradict.

In addition, in the fifth and sixth embodiments described above, each database stores not only the correction coefficient according to temperature or electric power, but also the accumulated charge/discharge amount of the storage battery 40 or the correction coefficient A for each usage period. It may be held as each table and stored in the database. That is, since the sensor error increases due to the usage load of the sensor and deterioration over time, the correction coefficient according to the characteristic may be stored in a database in advance and used.

Here, it is conceivable that the sensor may deteriorate as the accumulated charge/discharge amount increases or the usage period increases. That is, the error increases as the integrated charge/discharge amount increases or the usage period increases. The correction coefficient when the sensor has no error is 1, and the larger the error, the larger the absolute value of the difference between the correction coefficient and 1. That is, the correction coefficient is determined based on the integrated charge/discharge amount and the usage period. More specifically, the larger the integrated charge/discharge amount or the longer the usage period, the larger the absolute value of the difference between the correction coefficient and 1. (For example, 0.99→0.97→0.95, or 1.01→1.02→1.04, which changes according to an increase in error.)

The correction coefficient based on the deterioration characteristics over time can also be used in combination with the correction coefficient for each temperature or each electric power, or in combination with the correction coefficient calculated from the current measurement value. There are various ways of combining a plurality of correction coefficients, and there is no limitation. For example, each correction coefficient may be multiplied by a weighting coefficient (total weighting coefficient is 1) and added.
